Summary

What do they do? Malaria Consortium (malariaconsortium.org) works to save lives and improve health in Africa and Asia through evidence-based programs that combat targeted diseases and promote universal health coverage.1 This review focuses on its seasonal malaria chemoprevention (SMC) program, which distributes antimalarial drugs to children 3 to 59 months old in order to prevent illness and death from malaria, typically in four or five monthly cycles during the high transmission season; our recommendation is just for this part of Malaria Consortium's work. (More)

Does it work? There is strong evidence that SMC substantially reduces cases of malaria. Malaria Consortium has conducted studies in the countries where it has worked to determine whether its programs have reached a large proportion of children targeted. Surveys conducted in 2017-21 found that on average, for children targeted to receive four cycles of SMC, 95% were covered by SMC for at least one monthly cycle, 88% for at least two cycles, 77% for at least three cycles, and 65% for all four cycles. (More)

What do you get for your dollar? We estimate that the total cost to achieve the equivalent of one person-month of SMC coverage is about $1.50. The numbers of deaths averted and other benefits of SMC are a function of a number of difficult-to-estimate factors, which we discuss below. (More)

Is there room for more funding? We conduct "room for more funding" analysis to understand what portion of Malaria Consortium's ideal future budget it will be unable to support with the funding it has or should expect to have available. We may then choose to either make or recommend grants to support those unfunded activities. Our recent analyses of Malaria Consortium's room for more funding can typically be found by visiting the "Sources" sections of our published grant pages (see a list of grant pages here). (More)

Malaria Consortium's seasonal malaria chemoprevention program is recommended because:

  • SMC is a program with a strong evidence base and strong cost-effectiveness. (More)
  • Track record – Malaria Consortium has experience with supporting large-scale SMC programs in seven countries and has demonstrated success at reaching a large portion of targeted children. (More)
  • Room for more funding – we believe that Malaria Consortium could productively use more funding than it expects to receive to scale up its SMC activities. (More)

Our review process

We began speaking to Malaria Consortium about the possibility of reviewing one of its programs in January 2016.

Over the next several months we tried to determine which of Malaria Consortium's programs we should prioritize evaluating for a possible recommendation, and we ultimately settled on seasonal malaria chemoprevention (SMC). The other programs that we investigated included: bed nets, dengue control, injectable artesunate for severe malaria, integrated community case management (ICCM), micronutrient powders, malnutrition management, neglected tropical diseases morbidity management, integration of nutrition with SMC, prevention of malaria in pregnancy, point of care diagnosis of malaria, and diagnosis of pneumonia.

Our review process has consisted of:

  • Extensive conversations with Malaria Consortium staff since 2016.2
  • A conversation with a researcher at the London School of Hygiene and Tropical Medicine who has led the work on evaluating the ACCESS-SMC project, a large-scale SMC project led by Malaria Consortium.3
  • Reviewing documents that Malaria Consortium shared with us.

What do they do?

Malaria Consortium works on preventing, controlling, treating, and eliminating malaria and other communicable diseases.4 It was established in 2003 and currently works in thirteen countries across Africa and Southeast Asia.5 Malaria Consortium's total spending from April 2020 to March 2021 was about $92 million, with about 94% of its spending coming from restricted funds.6

This page focuses exclusively on its seasonal malaria chemoprevention (SMC) programs, which aim to distribute antimalarial drugs to children 3 months to 59 months old in order to prevent illness and death from malaria.7

The remainder of this section provides more detail on:

Implementation of SMC programs

What are SMC programs?

As we write in our intervention report on SMC, seasonal malaria chemoprevention is the intermittent (typically monthly) administration of full courses of antimalarial drugs to children during the malaria season in areas of highly seasonal malaria transmission.8 The original WHO policy recommendation for SMC, which was released in 2012, described SMC as the administration of "a maximum of four treatment courses of SP [sulfadoxine–pyrimethamine] + AQ [amodiaquine] at monthly intervals to children aged 3–59 months in areas of highly seasonal malaria transmission"9 and where resistance to SMC drugs was low.10 In 2022, the WHO updated its policy recommendation for SMC. The key changes included dropping the requirement that SMC be delivered only in places where drug resistance is low and allowing for variability in the number of cycles delivered. As a result, SMC—which has historically only been delivered at large scale in countries in the Sahel subregion of Africa, where drug resistance is low—can now be recommended in other areas with highly seasonal malaria transmission. Countries can also decide to deliver greater or fewer cycles of SMC, in line with the length of their peak malaria transmission seasons.11

According to Malaria Consortium, "SMC is primarily delivered door-to-door by trained community distributors. A full course of SP plus AQ (SPAQ) is given over three consecutive days. On the day of the community distributor’s visit to a household, one tablet of SP and one tablet of AQ are dispersed in water and administered under the supervision of a community distributor…The remaining two doses of AQ are given to the caregiver to disperse and administer once daily over the next two days...Each full course of SPAQ confers a high degree of protection from malaria infection for approximately 28 days."12

Malaria Consortium SMC implementation methods

Malaria Consortium supports training of health facility workers and community distributors (CDs) to deliver SMC primarily by going door-to-door.13 Some CDs are community health workers (CHWs), who are people in the community who support basic delivery of health interventions. The majority of CDs are recruited and trained to only deliver SMC and do not provide any other community health services.14 Malaria Consortium told us that CDs are typically paid about $5 to $7 per day for programs such as SMC, though this amount varies by country.15 Malaria Consortium also supports training for supervisors for the program.16

In the past, Malaria Consortium has typically supported four SMC cycles. Beginning in 2021, Malaria Consortium supported the governments of Burkina Faso and Nigeria in adding a fifth cycle of SMC (in addition to the usual four) in locations that are eligible for an additional cycle because their peak malaria transmission season is longer than in other SMC-eligible locations. It also supported an implementation research study in Uganda delivering five cycles.17 Each cycle includes a four- or five-day distribution period and lasts 28 days, at which point a new cycle starts.18 For each cycle, Malaria Consortium instructs CDs to:19

  1. determine whether the child is eligible for SMC and give the age appropriate dose.20
  2. refer all acutely sick children and children with fever to the health facility or a qualified community health worker for evaluation and testing for malaria.21
  3. directly observe the child swallowing the first dose of dispersible SP+AQ, and then re-dose if the child vomits or spits out all of the medicine within 30 minutes of taking the first dose of the medication.22
  4. give the child's caregiver 2 tablets of AQ and explain how to give the doses over the following two days.23
  5. record all doses provided on a tally sheet and mark the wall of the household or compound as visited.24
  6. advise the child's caregivers to mark a card to record that they've given the other two doses,25 to give the medication again if the child vomits (and to visit the health facility to request replacement doses if this happens), and to take the child to the health facility if they get a fever or are very sick.26
  7. provide health promotion and malaria prevention messages, including explaining the purpose and benefit of SMC and the importance of children and pregnant women sleeping inside a bed net each night.27

This is a diagram of the delivery schedule (for a four-cycle distribution):

Other relevant aspects of the program are:

  • Planning and enumeration. About five months before the SMC round, Malaria Consortium begins planning for the round and budgeting based on enumeration of the target population, personnel, and commodities costs.28
  • Procurement and supply management. Malaria Consortium procures SMC drugs and other commodities needed for SMC delivery. Malaria Consortium typically places orders for SMC drugs about a year before the start of the SMC round.29
  • ​​Training and supervision. Malaria Consortium trains CDs to identify eligible children, refer sick children to care, and record SPAQ administration.30 We do not know how often CDs follow all of the suggested instructions in practice. Program supervisors oversee CDs to provide mentoring and constructive feedback on implementation.31
  • Community engagement. Malaria Consortium supports activities to promote community engagement and social and behavior change before and during SMC campaigns.32
  • SMC research. Malaria Consortium also conducts operational research to assess the feasibility and impact of modifying the procedures described above, as well as implementation research and impact analyses. See this spreadsheet for a list of Malaria Consortium's SMC operational research projects in 2019 through 2021.

More details on how Malaria Consortium assesses the coverage achieved by the SMC programs it supports are below.

Malaria Consortium-supported SMC programs

We have seen information from three major SMC projects that Malaria Consortium has supported:

  • Pilot and scale-up of SMC in northern Nigeria: The Bill & Melinda Gates Foundation (BMGF) provided about $1.7 million to Malaria Consortium to do operational research on the best way to deliver SMC at scale in Katsina state in northern Nigeria, and then to implement its chosen delivery system and assess its efficiency and impact.33 Malaria Consortium told us that it trained over 3,600 CDs and nearly 200 health workers to provide about 1.6 million courses of SMC to roughly 350,000 children who lived in 4 "local government areas" (LGAs) in northern Nigeria in 2012-2014.34 A major goal of the project was to share what it learned; we have seen a published paper that describes the use of research to inform the design of an SMC intervention in northern Nigeria but have not yet reviewed it in detail.35
  • ACCESS-SMC:36 Unitaid awarded up to $67 million to Malaria Consortium to lead a project called ACCESS-SMC to reach up to 7 million children per year in seven countries in the Sahel region of Africa in 2015-2017.37 The project, which Malaria Consortium described in 2014 as being the "largest-yet global programme" for SMC, concluded in February 2018.38 ACCESS-SMC was led by Malaria Consortium, with Catholic Relief Services as the "primary sub-grantee" and support from many other organizations, including impact evaluation from the London School of Hygiene & Tropical Medicine (LSHTM).39 Malaria Consortium told us that its role in ACCESS-SMC included leading implementation of SMC in three of the seven ACCESS-SMC countries (Burkina Faso, Chad, and Nigeria), overseeing budgets and planning for all ACCESS-SMC activities, and overseeing research (including methodology and presentation).40 Our impression is that ACCESS-SMC paid for almost all aspects of program implementation and monitoring, including medicines and supplies, per diems for CDs, training for CDs, trainers, supervisors, and health facility workers, and research.41 ACCESS-SMC generated evidence for the subsequent scaleup of SMC by providing evidence of impact at scale under programmatic conditions.42
  • General SMC program funded primarily by GiveWell-directed funds: Since 2017, Malaria Consortium has been using funding received as a result of GiveWell's recommendation (which we refer to as "GiveWell-directed funds") to support SMC programs in several countries. Over time, the total number of children targeted by these programs has increased from about 660,000 in 2017 to about 12.2 million in 2021. In 2021, Malaria Consortium used GiveWell-directed funds to target approximately 2 million children in 29 districts in Burkina Faso, approximately 1.1 million children in 26 districts in Chad, approximately 8.4 million children in 129 LGAs in Nigeria, and approximately 490,000 children in 19 districts in Togo.43 In 2020-2021, it also conducted implementation research studies delivering SMC in Nampula, Mozambique, where it targeted approximately 70,000 children in two districts,44 and Karamoja, Uganda, where it targeted approximately 90,000 children in two districts.45

    In 2021, Malaria Consortium also received funding from the Korea International Cooperation Agency (KOICA) to cover some of the costs of SMC in one state in Nigeria46 and from The Bill and Melinda Gates Foundation to cover some of the costs of the research in Mozambique.47 Malaria Consortium co-funded SMC in some health districts in Burkina Faso with UNICEF and in some health districts in Togo with the Global Fund and with UNICEF.48 For this review, we focus on the portion of Malaria Consortium's SMC portfolio that is funded entirely or in part by philanthropic funding, including GiveWell-directed funding. We exclude the portion of Malaria Consortium's SMC portfolio that is funded exclusively by the Global Fund.49

Malaria Consortium's spending on SMC programs

Between January and December 2021, Malaria Consortium spent $50.5 million in GiveWell-directed funds:50

  • $17.8 million (35%) on SMC drugs, along with freight and procurement costs
  • $19.6 million (39%) on SMC implementation (including planning for SMC campaigns, training of supervisors and CDs, administration of SMC drugs, community engagement, and monitoring and evaluation, including coverage surveys)
  • $5.1 million (10%) on staff and travel costs51
  • $0.2 million (less than 1%) on equipment
  • $1.3 million (2%) on research, communications, and advocacy52
  • $6.5 million (13%) on overhead costs

Of this $50.5 million, Malaria Consortium spent $30.7 million (61%) in Nigeria, $9.9 million (20%) in Burkina Faso, $5.4 million (11%) in Chad, 1.7 million (3%) in Uganda, $1.4 million (3%) in Mozambique, and $1.4 million (3%) in Togo, with above-country spending allocated proportionally across countries.53

For prior work, we have also seen spending data from the pilot and scale-up of SMC in northern Nigeria,54 from 2016 for the ACCESS-SMC program,55 and from 2017-20 for programs supported by GiveWell-directed funds.56

We also provide some information on the estimated cost per SMC cycle of Malaria Consortium-supported SMC programs below.

Malaria Consortium's role in SMC programs

Malaria Consortium's SMC work varies by country, but in general aims to support countries' national malaria programs in implementing high-quality SMC campaigns, including the following activities:57

  • Determining the quantity of drugs needed, procurement of drugs, and international shipping.58
  • Procurement and distribution of other SMC commodities.59
  • Funding distributions, including in-country storage and transportation of drugs and payments to front-line distributors to compensate them for the time they spend on the program.
  • Technical assistance and logistical support for training SMC implementers, targeted supervision, community engagement and social and behavior change, drug safety, and review of prior implementation and revisions to procedures.
  • Financial management and oversight, including disbursing funds to local organizations, Ministries of Health, and/or CDs, collecting and validating receipts, and preparing financial reports.
  • Developing training and supervision materials and training staff at various levels.60
  • Monitoring and evaluation, including direct observation of program activities by Malaria Consortium staff, funding and coordinating with research firms and academic institutions to conduct coverage surveys and to track changes in malaria incidence and death, and monitoring of drug resistance.
  • Advocacy and fundraising with governments, international, multinational, and bilateral organizations, donors, SMC working groups, researchers, and civil society.
  • Conducting research that addresses knowledge gaps relating to SMC delivery, quality, and impact, writing and disseminating lessons learned and publications in peer-reviewed journals, and presenting at international global health conferences. See this spreadsheet for a list of Malaria Consortium's SMC research projects in 2019-2021.
  • In 2020, in order to continue implementing SMC during the COVID-19 pandemic, Malaria Consortium established enhanced safety and infection prevention guidance for program delivery, which included providing guidance for SMC delivery by community distributors, procuring items such as face masks and hand sanitizer, and revising training and supervision documents and job aids. In 2021, Malaria Consortium revised its infection prevention guidance for use during 2021 SMC rounds.61

Does it work?

We base our expectation of the impact of Malaria Consortium's SMC programs on:

  1. The evidence of effectiveness of SMC at reducing malaria incidence.
  2. Characteristics of the areas targeted by Malaria Consortium's SMC programs (including malaria incidence and seasonality).
  3. Evidence that a high proportion of targeted children have received SMC in past rounds.

We believe that the above provides strong indirect evidence that Malaria Consortium's SMC programs reduce malaria incidence in the populations they target. We also consider whether there is direct evidence of such reductions in these populations.

Finally, we consider whether there are factors that are not accounted for in the above evidence that would offset the impact of Malaria Consortium's SMC programs, either through reducing their effectiveness or contributing to negative outcomes.

Is SMC an effective intervention?

Seven randomized controlled trials (RCTs) provide strong evidence that SMC substantially reduces cases of malaria. We discuss this evidence in our intervention report on SMC. We incorporate SMC's impact on malaria incidence, as measured by these RCTs, into our cost-effectiveness model.62

Are Malaria Consortium's SMC programs targeted at areas where they are likely to be effective?

Malaria Consortium told us that before starting work in countries under the ACCESS-SMC program, it conducted an assessment of the overall burden of malaria, transmission and rainfall patterns, regional malaria incidence over time, and seasonal variations in malaria.63 We have not reviewed this evidence in detail, but it seems highly likely to us that Malaria Consortium is working in areas that are suitable for SMC because it is working in countries with high malaria burdens and where it seems that malaria is seasonal.64 More information on our estimates of malaria burden in the countries where Malaria Consortium is working is available in our cost-effectiveness model.65

Are targeted children reached with SMC?

Malaria Consortium conducts coverage surveys to determine what proportion of the target population (children aged 3-59 months) was reached with SMC in the previous round or cycle. We use results from past SMC rounds to understand the impact we should expect future rounds to have. Specifically, we use coverage survey results about the proportion of targeted children reached, along with data on program spending, to estimate the cost of delivering SMC to a child. Our interpretation of these coverage survey results is informed by their comprehensiveness and the methodology used to collect them.

Comprehensiveness

See this spreadsheet for all coverage survey results we have seen from Malaria Consortium's SMC programs. In short, we have seen results from all large-scale SMC programs66 that Malaria Consortium supported with GiveWell-directed funds through 2021. This includes results from 2017-2021 in Burkina Faso, Chad, and Nigeria, from 2020-2021 in Togo, and from 2021 in Uganda and Mozambique.67

We have also seen results from 2015-2016 in the seven countries that Malaria Consortium supported through the ACCESS-SMC project. We thus believe that we have seen a thorough picture of the impact of Malaria Consortium's SMC program; we incorporate this assessment into our cost-effectiveness model.68

We focus our review on results from 2017 onward in Burkina Faso, Chad, and Nigeria and from 2020 onward in Togo, as we believe they are more likely to be indicative of what we can expect from future SMC rounds in those countries. We do not focus on results from Mozambique and Uganda because Malaria Consortium was operating at a small scale and doing implementation research in these countries in 2021, so we don't expect results to provide a good indication of the coverage that it might achieve in future program years.69

Methodology

Since 2017, Malaria Consortium has conducted two types of coverage surveys. After all but the final cycle in the SMC round, it conducts a post-cycle coverage survey to measure coverage in the previous cycle only.70 After the final cycle in the SMC round, it conducts a post-round coverage survey to measure coverage across the full round.71 Both post-cycle and post-round surveys involve household interviews with caregivers of SMC-eligible children. Full details of the methodology used in the surveys we have reviewed are in the "Methods" sheets of this spreadsheet.

Below, we summarize Malaria Consortium's general post-cycle and post-round coverage survey methodology and discuss methodological strengths and weaknesses. Overall, we believe that both types of surveys are designed to measure key indicators of the success of SMC campaigns and to achieve samples that are generally representative of target populations. However, we are concerned that the self-reported nature of responses and data collectors' involvement in the later stages of respondent selection may produce bias in results. In general, we have also been uncertain about the quality of survey implementation due to the lack of a procedure to audit data collectors' work; in 2021, auditing measures were introduced into post-round and post-cycle surveys in Nigeria (and post-round surveys in Mozambique and Uganda).72 We see this as a methodological strength, both because such a procedure may encourage accurate data collection and because it provides a check on the accuracy of results. Results from the auditing of post-round surveys in Nigeria suggest that in the vast majority of cases, data collection procedures were followed correctly, though some instances of interviews being done incorrectly or results being fabricated were found.73 We incorporate our assessment of the quality of Malaria Consortium's coverage survey methodology into our cost-effectiveness model74 and into our qualitative assessment of Malaria Consortium's organizational strength.

  • Respondent selection: Post-cycle surveys employ lot quality assurance sampling75 in which the program area is subdivided into smaller units, generally of approximately equal population size, and a small number of households is randomly selected from each unit.76 While this approach is primarily designed to assess whether each unit met a target coverage level, data from all units can be aggregated to calculate coverage across the program area. Because all units are sampled and are of approximately equal population size, we expect this selection protocol to result in a sample that is generally representative of the target population.77 Post-round surveys employ multi-stage cluster sampling of households in the program area, with sampling units above the household level generally selected randomly with probability proportional to size.78 We expect this selection protocol to result in a sample that is generally representative of the target population.

    For both types of surveys, data collectors are instructed to randomly select households to survey. In some surveys we have reviewed, data collectors were instructed to use numbered household lists from which they selected households using randomly generated numbers. In other surveys, data collectors were instructed to spin a bottle at a central point in the community to choose a direction along which they then selected a predetermined number of households at a predetermined interval.79 This latter method may lead households closer to the center of a community to be overrepresented in the sample. We are unsure of how this might bias results, though it seems plausible that households on the outskirts of a community may have been less likely to be reached by SMC, and thus that results would be biased upward.

    Next, data collectors enter all children aged 3-59 months (the eligible age range for SMC) in the selected household into survey software. The survey software then randomly selects a child, and data collectors ask caregivers questions about that child.80

    We see it as a methodological strength that child selection is randomized by survey software. However, we see data collectors’ involvement in the later stages of respondent selection as a potential concern. Data collectors may apply selection procedures incorrectly, either unintentionally or intentionally. If, for example, they purposefully select households that are easier to reach, this would be a potential source of upward bias, as households that are easier to reach may also have been more likely to be reached by SMC. We note that we have seen no evidence that data collectors intentionally applied selection procedures incorrectly and note it only as a possibility.

    If a selected household is unavailable or refuses to participate in the survey, data collectors are instructed to move to the next household according to the sampling procedure. In the 2019-21 post-round surveys, 98% or higher of the targeted number of households were interviewed.81 This could mean that non-response rates (i.e., households randomly selected to be interviewed not being interviewed) were low. However, because we do not know how often replacement households were used, it is also possible that a high proportion of interviewed households were replacement households, so these survey completion rates only slightly increase our confidence in the accuracy of results from these surveys. The post-cycle survey completion rates for 2020-2021 from Burkina Faso, Chad, Nigeria, and Togo were 90% or higher, with the exception of Plateau state in Nigeria in 2021.82

  • Survey design: Malaria Consortium has developed post-cycle and post-round questionnaires,83 which are adapted for use in each country. Questionnaires are translated from English into French in Burkina Faso, Chad, and Togo, and into Portuguese in Mozambique.84 These questionnaires instruct data collectors to ask caregivers questions about whether their child received SPAQ during the previous cycle (in the case of post-cycle surveys) or during all cycles of the round (in the case of post-round surveys). Both questionnaires ask about SPAQ provided by a CD on the first day of each cycle and about AQ provided by the caregiver on the second and third days of each cycle. They also ask questions about the quality of program delivery. Data collectors translate questions from English, French, or Portuguese into local languages during household interviews,85 which may lead to inconsistencies in translation and reduce the accuracy of results.

    A potential source of bias in Malaria Consortium's coverage surveys is their heavy reliance on self-reported responses. Post-round responses are at high risk of recall bias, as they report on up to 12 or 15 doses,86 the first of which would have occurred at least three or four months prior.87 Post-cycle responses are at lower risk of recall bias, as they ask only about three doses and are conducted within two weeks to a month of those doses.88 Self-reported responses are also at risk of social desirability bias that could lead caregivers to overreport SMC administration, if they believe that this is the preferred response of data collectors. We expect responses about caregivers' own administration on the second and third days of each cycle to be at greater risk of this type of bias, as they may feel pressure to overreport their own adherence to program guidance. Because the coverage estimates we use are based on responses about CDs' administration on the first day of each cycle,89 about which we believe caregivers may feel less pressure to report positively, this is a smaller concern.

    We would have more confidence in a survey that tested the reliability of self-reported responses against some objective measure. In order to verify caregiver responses, data collectors are instructed to review children's SMC record cards and drug blister packs, if available.90 However, retention of these items has generally been low, leading Malaria Consortium to place low weight on them as indicators of coverage.91

  • Survey implementation: In general, Malaria Consortium contracts with local research organizations that recruit data collectors and oversee survey implementation.92 Individuals involved in the surveys generally were not involved in SMC delivery, which suggests that they are unlikely to have a personal interest in survey outcomes.93 Malaria Consortium has reported a few cases in which surveys conducted by local research organizations were of low quality;94 this may have impacted the accuracy of results, but we are uncertain about the magnitude or direction of this impact.

    Malaria Consortium's coverage surveys have not systematically incorporated an auditing procedure to assess the accuracy of data collectors' work. In 2021, auditing measures were introduced into post-round and post-cycle surveys in Nigeria (and post-round surveys in Mozambique and Uganda).95 We see this as a methodological strength, both because such a procedure may encourage accurate data collection and because it provides a check on the accuracy of results. We have not seen results from the audits of Nigeria post-cycle and Mozambique and Uganda post-round surveys. We have seen results from the audits of post-round surveys in Nigeria in 2021, for which several methods were in place to check enumerators' entries: supervisors tracked enumerators' GPS locations to ensure that they visited the correct communities, listened to a portion of audio recordings taken of interviews, and re-surveyed a portion of households to check that interviews had been conducted according to survey protocol. The vast majority of supervisor re-surveys uncovered no issues, which increases our confidence that data collection procedures were usually followed correctly. However, decreasing our confidence in results is the fact that 3% of the interviews that were subject to GPS auditing and 4% of the interviews that were subject to audio auditing were done incorrectly or fabricated. While these results were then removed from the data set, their random selection suggests that a similar proportion of the unaudited results could have issues. (We aren't sure how to reconcile the different rates of issues found by supervisor re-surveys and GPS and audio auditing.)96 In addition, we have seen data from repeat interviews conducted in Nigeria in 2017.97

  • Data capture: Data is collected electronically in both post-cycle and post-round coverage surveys and uploaded to a remote server at the end of each day of data collection.98 One concern we have about coverage surveys in general is that data may be lost after being collected. As mentioned above, from 2019-2021, data was collected and uploaded from 98% or higher of the number of households that were targeted to be interviewed in post-round surveys and from 90% or higher of households targeted in post-cycle surveys in 2020-2021. This leads us to believe that it is unlikely that substantial data loss occurred after collection.

Results

We believe that results from Malaria Consortium's coverage surveys provide strong evidence that a high proportion of the target population was reached with SMC in past rounds. We use these coverage estimates, along with data on program spending, to estimate the cost of delivering SMC to a child.

See this spreadsheet for all results we have seen from Malaria Consortium's SMC programs. Results weighted by target population from post-round surveys in 2017-2021 show that across those years, for children targeted to receive four cycles of SMC, 95% were covered by SMC for at least one monthly cycle, 88% for at least two cycles, 77% for at least three cycles, and 65% for all four cycles.99 In the most recent program years, post-round surveys measured average coverage across cycles at 92% in Burkina Faso (2018-2020), 85% in Chad (2018-2021), 78% in Nigeria (2018-2021), and 87% in Togo (2020-2021).100

For coverage surveys in 2017-2021, we have compared results from post-cycle and post-round surveys. After converting the two sets of coverage estimates into a measure of total person-months of coverage for comparison, we find a difference of 2% between them for 2017, 13% for 2018, 24% for 2019, 9% for 2020, and 6% for 2021.101 We find it concerning that this difference is high in some years. We don't know why, overall, it increased from 2017-2019 and then decreased in 2020 and 2021, but we have attempted to understand the main drivers of this difference for each year. In general, the difference has been driven by results from Nigeria, with results from Chad also contributing to the difference in 2019.102 From 2018 to 2021, post-cycle results found higher person-months of coverage than post-round results.103 Differences in sampling protocol and questionnaire design between the two types of surveys may inevitably lead to some difference in results. However, the fact that post-cycle and post-round results were similar in Burkina Faso in 2017-2020, in Chad in 2017-2018 and 2020-2021, and in Nigeria in 2017 leads us to believe that larger discrepancies cannot be explained merely by methodological differences and likely result from biases present in the surveys in Chad in 2019 and in Nigeria in 2018-2021. In cases where the discrepancy is large, we believe that the post-round results are a better indication of actual coverage104 and have chosen to use these results to estimate the cost of delivering SMC to a child.

Have malaria rates decreased in targeted populations?

The evidence we have discussed to this point forms the basis of our expectation of the impact of Malaria Consortium's SMC programs. In this section, we consider whether there is additional evidence on the impact or efficacy of SMC that either corroborates this expectation or raises concerns that Malaria Consortium's programs are not achieving the impact we expect.

Sentinel surveillance site data (2013-2016)

We have seen sentinel surveillance site data from Chad, Mali, and Niger for 2013 to 2016 and from Burkina Faso and Nigeria for 2015 to 2016.105 We have received only headline figures for the reduction in malaria cases in children under 5 years old; we have not seen additional information on the sources for or analysis of this data.106 We have therefore not vetted the results (described in the footnote).107 Malaria Consortium told us that the data collected in other ACCESS-SMC countries was of a low quality.

Health Management Information System (HMIS) data

In 2019, Malaria Consortium conducted an assessment of the impact of SMC on malaria rates in Burkina Faso and Chad from 2013 to 2018 and Nigeria from 2017 to 2018, using national HMIS data.108 This assessment found no evidence of impact.109 Malaria Consortium attributes this result to several factors, in particular the variable and generally low quality and completeness of HMIS data used in the analysis.110

Malaria Consortium notes that it chose to analyze HMIS data, despite the fact that it is typically of low quality, because it is an inexpensive and commonly used source of impact data and therefore a relatively sustainable method for assessing impact over the long term.111 Given our understanding that collecting high-quality health facility data is difficult, we find Malaria Consortium's explanation plausible.

Our overall assessment of the expected impact of SMC places little weight on the lack of impact found in HMIS-based impact assessments because:

  • Non-randomized comparisons between areas in which SMC is implemented and not implemented may over or understate the impact of SMC due to differences in the two groups other than presence of SMC.
  • We believe that there is a risk that data quality limitations will be emphasized more where non-positive trends are found than where positive trends are found. Independently assessing the quality of HMIS data would be a large project for us and we have not prioritized that work.

As noted above, we base our expectation of the impact of Malaria Consortium's SMC programs on malaria rates on the evidence of effectiveness of SMC at reducing malaria incidence, as measured by RCTs, and evidence from Malaria Consortium's coverage surveys that a high proportion of targeted children have received SMC.

Case-control studies

Malaria Consortium also shared case-control studies designed to measure the efficacy of SMC from five ACCESS-SMC countries: Burkina Faso, Chad, The Gambia, Mali, and Nigeria. We have not yet vetted the methodology (some details in the footnote), and the dataset from Nigeria did not pass quality control.112 Malaria Consortium's conclusion from these studies is, "These results confirm that SMC treatments are providing a very high degree of personal protection from malaria for a period of 28 days after each treatment. Protection then declines rapidly emphasizing the importance of repeating treatments at monthly intervals."113 More details on those results in this footnote.114

Northern Nigeria (2012-2014)

We have seen three types of analyses of the impact of Malaria Consortium's northern Nigeria program on malaria indicators. These results seem to be consistent with the impacts of SMC found in randomized controlled trials of the program, but due to our remaining questions about the studies we do not yet see them as strong additional evidence for the impact of SMC programs. See our previous review of Malaria Consortium for more details on this study.

Are there any negative or offsetting impacts?

In this section, we consider factors that are not accounted for in the above evidence that could offset the impact of Malaria Consortium's SMC programs, either through reducing their effectiveness or contributing to negative outcomes.

  • Drug resistance: Mass delivery of SMC medicines could contribute to increased drug resistance of SP and/or AQ.115 In 2015, ACCESS-SMC funded a baseline study of the prevalence of gene mutations in malaria parasites that are markers of drug resistance for the drugs used in SMC.116 A follow-up survey was conducted in 2017, following two rounds of SMC.117 We have lightly reviewed a preliminary report from this survey, which reported that between baseline and follow-up, the prevalence of mutations associated with AQ resistance did not increase and that the prevalence of mutations associated with SP resistance did increase.118 It also reported that no samples were collected that contained both mutations associated with AQ resistance and mutations associated with SP resistance.119 We have received the final report from this survey but have not yet reviewed it in depth. In our cost-effectiveness model, we make a small downward adjustment in our estimate of SMC's impact to account for the possibility of development of drug resistance.120
  • Possible "rebound" effects: There is a potential concern that SMC could reduce the natural development of immunity to malaria. After children turn five years old and are no longer eligible to receive SMC or if SMC programs are interrupted by lack of funding or other problems, children could lack immunity and be more susceptible to malaria, especially if other prevention methods, such as long-lasting insecticide-treated nets (LLINs), are not used. We have not yet investigated this concern in-depth. In our cost-effectiveness model, we make a small downward adjustment in our estimate of SMC's impact to account for the possibility of rebound effects.121
  • Side effects of SMC drugs: Our impression is that the most common reaction seen with SMC drugs in earlier programs was vomiting (AQ is bitter and had to be crushed into a powder and mixed with water); for a number of years, AQ has been available as an orange-flavored dispersible, which improves the taste and makes the drug more easily ingestible.122 Malaria Consortium told us that the incidence of vomiting has decreased with the dispersible formulation.123 If the child expels the drugs within 30 minutes, they are supposed to be re-dosed once; we are unsure whether caregivers typically request extra tablets of AQ from CDs when this happens at home to ensure their child gets a full course of SPAQ.124 Our impression is that other side effects from these drugs are rare and include diarrhea, itching, headache, mild abdominal pain, and rash.125 Severe adverse effects associated with SPAQ are rare. A study in Nigeria that followed up with 10,000 SMC recipients one week after receiving SMC resulted in only five reports of severe adverse events, though Malaria Consortium believes there may have been reluctance to report issues.126 Malaria Consortium shared three resources that report very low severe adverse event rates from SMC drugs (available in the following footnote).127 We have lightly reviewed resources on severe adverse event rates from SMC drugs here. In our cost-effectiveness model, we make a small downward adjustment in our estimate of SMC's impact to account for the possibility of severe adverse effects.128
  • Drug quality and dosage: Malaria Consortium told us that its policy is to only procure products from suppliers that meet WHO guidelines for pre-qualification quality assurance standards,129 and that these products are approved and quality-assured by the governments of countries where Malaria Consortium works.130 We have not yet asked Malaria Consortium for the details of these processes. If there were issues with drug quality or dosage, it could reduce the effectiveness of the intervention and lead to more rapid development of drug resistance.

What do you get for your dollar?

Cost per SMC cycle administered

In order to make program costs comparable across all of our top charities, we aim to estimate the total cost to all actors of supporting a given program. Our estimate of the cost per SMC cycle administered includes research costs and costs incurred by actors such as governments. Our estimates rely on coverage survey estimates to approximate the number of children reached.

With these assumptions, using information from Malaria Consortium's programs between 2018 and 2021, we estimate that the total cost to achieve the equivalent of one person-month of SMC coverage is about $1.50. We have access to cost and coverage data starting in 2015 for Burkina Faso, Chad, and Nigeria;131 however, we have chosen to include data only from more recent years because we believe it provides a better indication of the cost per SMC cycle administered that Malaria Consortium will achieve in future years. (The downside of this approach is that our estimates of cost per SMC cycle administered exclude start-up costs, though these costs are a sufficiently small proportion of total costs over time that their exclusion does not substantially impact our estimates.) Full details and country-specific estimates are available in this spreadsheet.132

We start with this total cost figure and apply adjustments in our cost-effectiveness analysis to account for cases where we believe the charity's funds have caused other actors to shift funds from a less cost-effective use to a more cost-effective use ("leverage") or from a more cost-effective use to a less cost-effective use ("funging").

Cost-effectiveness

See our page on impact estimates for estimates of the cost per life saved through Malaria Consortium-supported SMC programs and how our model compares this outcome with outcomes of other programs.

Note that our cost-effectiveness analyses are simplified models that do not take into account a number of factors. For example, our model does not include the short-term impact of non-fatal cases of malaria prevented. It also does not include possible offsetting impacts or other harms.133

There are limitations to this kind of cost-effectiveness analysis, and we believe that cost-effectiveness estimates such as these should not be taken literally, due to the significant uncertainty around them. We provide these estimates (a) for comparative purposes and (b) because working on them helps us ensure that we are thinking through as many of the relevant issues as possible.

Is there room for more funding?

We conduct "room for more funding" analysis to understand what portion of Malaria Consortium's ideal future budget it will be unable to support with the funding it has or should expect to have available. We may then choose to either make or recommend grants to support those unfunded activities. Our recent analyses of Malaria Consortium's room for more funding can typically be found by visiting the "Sources" sections of our published grant pages (see a list of grant pages here).

Room for more funding analysis

In general, we assess top charities' funding needs over a three-year period.134 We ask top charities to report their ideal budgets over the next three years, along with information about their current available funding and funding pipeline. The difference between a charity's three-year budget and the funding we project that it will have available to support that budget is the charity's "room for more funding."

For this analysis, we focus on the portion of Malaria Consortium's SMC portfolio that is funded entirely or in part by philanthropic funding, including GiveWell-directed funding. We exclude the portion of Malaria Consortium's SMC portfolio that is funded exclusively by institutional funding.135

The main components of our room for more funding analyses are:

  • Available funding. We ask top charities to report how much funding they currently hold in the bank, including in reserves, and how much of this funding is committed or expected to be spent on specific future activities. The difference between these figures is the amount available to allocate to the charity's unfunded spending opportunities.
  • Expected funding. We project the amount of additional funding that top charities will receive to support their work over the next three years. These projections represent our best guesses based on top charities' past revenue and our understanding of their funding pipelines. They typically include funding currently held by GiveWell to be granted to the top charity, projected funding due to being a GiveWell top charity,136 and, if the top charity is part of a larger organization, projected unrestricted funding from that parent organization. They exclude any funding we may specifically recommend to the top charity subsequent to the analysis. We add this projected funding to the amount available to allocate to the charity's unfunded spending opportunities.
  • Spending opportunities. We ask top charities to report their ideal budgets in each of the next three years and to provide details on the specific spending opportunities included in these budgets. These opportunities are typically presented as one program year in a specific implementation geography (for example, SMC in Nigeria in 2023), and they can represent either an extension of the top charity's previous support to a geography or an expansion of support to a new geography. We ask top charities to report the order in which they would prioritize funding these opportunities, which helps us to understand how available and expected funding will be allocated and what the marginal impact of additional funding beyond that amount would be.

A charity's room for more funding represents the total budget for the charity's spending opportunities, less its available and expected funding. For example, if a charity proposes spending $50 million over the next three years and holds $10 million in uncommitted funding, and we project that it will receive an additional $15 million in revenue over the next three years, that charity's room for more funding is $25 million. (Note that a charity's total room for more funding figure includes funding gaps at all levels of cost-effectiveness—see below.) Our recent analyses of Malaria Consortium's room for more funding can typically be found by visiting the "Sources" sections of our published grant pages (see a list of grant pages here).

Grant investigation process

Room for more funding analysis is a key part of our grant investigation process. We periodically request the information described above from top charities and update our room for more funding analyses. Our default is to update each top charity's room for more funding analysis annually, though we may choose to do so more or less frequently. The cadence on which we conduct updates depends largely on how often we grant funding to a top charity137 and how much we expect that charity's funding and budgets to have changed since our most recent funding decision.138 We have typically updated our analysis of Malaria Consortium's room for more funding on an annual basis, and have completed additional ad hoc updates prior to large grant decisions. Our recent analyses of Malaria Consortium's room for more funding can typically be found by visiting the "Sources" sections of our published grant pages (see a list of grant pages here).

After completing such an update, we may then choose to investigate potential grants to support the spending opportunities that we do not expect to be funded with the charity's available and expected funding, which we refer to as "funding gaps." The principles we follow in deciding whether or not to fill a funding gap are described on this page.

The first of those principles is to put significant weight on our cost-effectiveness estimates. We use GiveDirectly's unconditional cash transfers as a benchmark for comparing the cost-effectiveness of different funding gaps, which we describe in multiples of "cash." Thus, if we estimate that a funding gap is "10x cash," this means we estimate it to be ten times as cost-effective as unconditional cash transfers. As of this writing in January 2023, we are focused on funding opportunities that meet or exceed a relatively high bar: 10x cash, or ten (or more) times as cost-effective as GiveDirectly's unconditional cash transfers. (Note that a charity's total room for more funding figure includes funding gaps at all levels of cost-effectiveness.)

If we decide to fill a funding gap, we either make a grant from our Top Charities Fund139 or recommend that another funder—typically Open Philanthropy140 —makes a grant. This page lists all grants made or recommended by GiveWell. Typically, when GiveWell donors make a donation to a top charity,141 we don't expect that donation to be directed to a specific funding gap, but rather to contribute to supporting the overall portfolio of opportunities included within a charity's room for more funding.

Availability of unrestricted funding

Since Malaria Consortium works on a variety of programs, it is possible that receiving additional funds for its SMC work could lead it to reallocate unrestricted funds or other organizational resources (such as time spent fundraising) toward other programs, so that additional dollars donated to Malaria Consortium would not fully support additional SMC work. However, we do not see this as a major concern because we do not believe that Malaria Consortium has substantial unrestricted funding available, and it seems that Malaria Consortium has not allocated substantial unrestricted funding to SMC work in the past (see footnote for details).142

Malaria Consortium as an organization

We use qualitative assessments of our top charities to inform our funding recommendations. See this page for more information about this process and for our qualitative assessment of Malaria Consortium as an organization.

    "In March 2012, the World Health Organisation (WHO) issued a policy recommendation for a new intervention against Plasmodium falciparum malaria - seasonal malaria chemoprevention (SMC), previously referred to as intermittent preventive treatment in children (IPTc), in children under five years old. SMC is defined as the intermittent administration of full treatment courses of an anti-malarial treatment combination during the malaria season to prevent illness and death from the disease.

    The objective is to maintain therapeutic anti-malarial drug concentrations in the blood throughout the period of greatest risk. This will reduce the incidence of both simple and severe malaria disease and the associated anaemia and result in healthier, stronger children able to develop and grow without the interruption of disease episodes. SMC has been shown to be effective, cost effective and feasible for the prevention of malaria among children in areas where the malaria transmission season is no longer than four months."

    "Across the Sahel sub-region, most childhood malarial disease and deaths occur during the rainy season, which is generally short (3-4 months).

The updated recommendation recognizes that countries in other parts of Africa with highly seasonal variation in malaria burden could also benefit from SMC, and that the availability of new medicines could make it a viable intervention in these areas.

    The original recommendation stated that a maximum of 4 monthly doses of SMC should be given during the malaria transmission season. The updated guidance states that SMC should be given during peak malaria transmission season, without defining the specific number of monthly cycles. … While the original recommendation restricted SMC use to children less than 6 years of age, the new recommendation recommends this intervention for children at high risk of severe malaria, which may extend to older children in some locations."

    • "How is SMC delivered?
      Local announcements each month will inform the community about the date of SMC, which will be delivered by community health workers at pre-arranged locations in the community, or by visiting each household. Health workers will receive appropriate training before the intervention begins and will be supervised by nurses and the district health team."ACCESS-SMC project brochure, Pg 3. Malaria Consortium noted that health workers are also sometimes trained for SMC programs (comment provided in response to a draft of this page in October 2017).
    • For Malaria Consortium's SMC program in Nigeria: "House to house delivery method was the most used approach, as reported by 88.2 percent of the respondents. This was similar across the LGAs [local government areas] though Maiadua had slightly higher numbers receiving through the fixed point delivery approach. The duration spent in receipt of drugs in the home was 20 minutes, half the time spent in receipt of drugs from a fixed point which was 47 minutes. Knowledge of the different types of SMC drugs and dose duration was high at over 80 percent. This highlights house to house delivery of SMC as a quicker and most preferred delivery mechanism by the caregivers. There is need for costing the two delivery mechanisms to assess if home based delivery still remains a cost effective delivery channel." Malaria Consortium, Nigeria SMC evaluation report, 2014, Pg 38.
    • For ACCESS-SMC delivery methods, see the annexes on Pgs 31-70 of ACCESS-SMC multi-country cost analysis, January 2017. Sample quote: "A combination of 6,500 trained community distributors and 355 health facility staff (e.g. nurses and midwives) administered SMC by way of two distribution methods: door-to-door (two-person teams) and at fixed points located at health centers (one-person teams) which were in place to serve primarily as referral centers for sick children and provide SMC to children who were came to the facility. It was estimated that 90% of SMC was distributed by door-to-door teams and 10% was distributed at fixed points. To ensure the acceptability of SMC and high rates of coverage within communities, 3,483 trained community mobilizers sensitized communities on the benefits of SMC prior to and during each distribution cycle."

    "Some community distributors are community health workers — a recognized cadre of community-based primary healthcare workers who receive a small stipend from the government and who provide basic health services in their communities. In most countries, the majority of community distributors are volunteers recruited and trained specifically for the SMC campaign. Community distributors typically work in pairs."

    "During SMC distribution, community distributors are assisted by field supervisors who receive more in-depth training on supervision and mentoring skills. Each team of community distributors should be observed by, and receive constructive feedback from, a supervisor at least once every cycle. Supervision is coordinated by health workers at the health facilities that serve as functional units for SMC distribution, sometimes with support from community health workers. Malaria Consortium staff and local, regional, and central health authorities also support the supervision of SMC implementers."

    Malaria Consortium, comments on drafts of this page, October 2019 and October 2020.

  • 28"An SMC campaign typically begins around five months before the start of the annual SMC round. This involves agreeing campaign dates and modalities at the national and state levels, as well as reflecting on lessons learned in previous years to inform adaptations to the SMC intervention tools and protocols. Micro-planning at the subnational level is conducted about four months before the start of the SMC round, including budgeting based on detailed enumeration of the target population at the subnational level, required personnel, and commodities." Malaria Consortium’s seasonal malaria chemoprevention program: Philanthropy report 2021, p. 11
  • 29“The manufacturing lead time can be up to 10 months and, consequently, orders need to be placed around one year before the start of the annual SMC round. The medicines need to be transported from the manufacturers’ production plants in China and India to ports in Africa, preferably by sea owing to the lower freight cost, or by air at a higher cost if the consignment is more urgent. Once the medicines have passed country-level customs and quality assurance procedures, they are distributed further using country-level supply chain mechanisms, typically to the state or health district level, the lowest administrative level where suitable storage facilities exist. In addition to SPAQ, SMC commodities include, for example, branded T-shirts, hijabs, bags, and pens, as well as items required to minimize the risk of COVID-19 infection among SMC implementers and communities, such as face masks and hand sanitizer. Last-mile distribution—the transport of commodities to the health facilities that serve as functional units for the SMC campaign —happens just before the start of SMC distribution. This can be challenging due to poor infrastructure and limited storage facilities. Supply management also involves reverse logistics, which is the process of transporting SMC commodities back to a central warehouse at the end of the cycle or annual round.” Malaria Consortium’s seasonal malaria chemoprevention program: Philanthropy report 2021, p. 12.
  • 30"SMC implementers are trained through a cascade model beginning at the national level about two months before the start of the annual SMC round, with each cadre of trainers subsequently training the next lower level of trainers and learners. Community distributors are typically trained at the health facility level. SMC training includes modules on identifying eligible children, referring sick children to a health facility, administering SPAQ safely, recording SPAQ administration, interpersonal communication, and safeguarding. In some countries, separate trainings are conducted on supply chain management and health education." Malaria Consortium’s seasonal malaria chemoprevention program: Philanthropy report 2021, p. 12.

        Led by Malaria Consortium, SuNMaP was jointly managed by a consortium, including lead partners Health Partners International and GRID Consulting, with nine other implementing partners. SuNMaP was implemented in 10 states across Nigeria, including Anambra, Kano, Niger, Katsina, Ogun, Lagos, Jigawa, Enugu, Kaduna and Yobe.

        SuNMaP worked with the Nigerian government's National Malaria Elimination Programme (NMEP) to harmonise donor efforts and funding agencies around national policies and plans for malaria control. Project targets were aligned with the National Malaria Strategic Plan and Global Malaria Action Plan. The project aimed to improve national, state and local government level capacity for the prevention and treatment of malaria." Malaria Consortium, SuNMaP Final Report, Pg 38.

    • Strachan et al. 2016 Abstract:
      • "Background: Experience of seasonal malaria chemoprevention (SMC) is growing in the Sahel sub-region of Africa, though there remains insufficient evidence to recommend a standard deployment strategy. In 2012, a project was initiated in Katsina state, northern Nigeria, to design an appropriate and effective community-based delivery approach for SMC, in consultation with local stakeholders. Formative research (FR) was conducted locally to explore the potential feasibility and acceptability of SMC and to highlight information gaps and practical considerations to inform the intervention design.
      • Methods: The FR adopted qualitative methods; 36 in-depth interviews and 18 focus group discussions were conducted across 13 target groups active across the health system and within the community. Analysis followed the ‘framework’ approach. The process for incorporating the FR results into the project design was iterative which was initiated by a week-long ‘intervention design’ workshop with relevant stakeholders.
      • Results: The FR highlighted both supportive and hindering factors to be considered in the intervention design. Malaria control was identified as a community priority, the community health workers were a trusted resource and the local leadership exerted strong influence over household decisions. However, there were perceived challenges with quality of care at both community and health facility levels, referral linkage and supportive supervision were weak, literacy levels lower than anticipated and there was the potential for suspicion of ‘outside’ interventions. There was broad consensus across target groups that community-based SMC drug delivery would better enable a high coverage of beneficiaries and potentially garner wider community support. A mixed approach was recommended, including both community fixed-point and household-to-household SMC delivery. The FR findings were used to inform the overall distribution strategy, mechanisms for integration into the health system, capacity building and training approaches, supportive interventions to strengthen the health system, and the social mobilization strategy.
      • Conclusions: Formative research played a valuable role in exploring local socio-cultural contexts and health system realities. Both opportunities and challenges for the introduction of SMC delivery were highlighted, which were appropriately considered in the design of the project."

We require countries to carry out a revised quantification every year based on consumptions and stocks from previous years, consolidate orders, recruit procurement agent, negotiate pricing points with Guilin (and in the future, more pharma companies we hope), we monitor production and shipment schedules and make sure country teams are aware of when drugs come / delays, etc. Countries are responsible for providing us with all the relevant import requirements to make sure that all documentation is ready when drugs arrive. They then work out with local clearing agents the custom procedures, tax waivers, etc, and proceed with whatever logistics options / approaches are relevant in their countries (from direct delivery to peripheral health units as in Nigeria, to mixed approaches involving MoH storage and MC / CRS transport, to full contracting with MoH-mandated central pharmacy – depends on context)."

    In 2017, Malaria Consortium supported one region in Guinea Bissau with SMC but did not conduct a coverage survey. "Due to the size of the country, and the expected transient nature of Malaria Consortium support there, it was decided not to include any coverage surveys in Guinea Bissau." Malaria Consortium, Summary Update, May 2018, Pg. 6.

    We do not view this as a major limitation, as a relatively small portion of Malaria Consortium's spending in 2017 went to this program. See this spreadsheet, Sheet "Past spending by category, May 2017-Feb 2018," row "Guinea Bissau 'GiveWell Districts'."

    Malaria Consortium conducts two types of coverage surveys: post-cycle and post-round surveys. It has conducted a post-round survey after each SMC round supported with GiveWell-directed funds, though the 2021 post-round survey in Burkina Faso was not nationally representative (see cell note in cell A43 here). Malaria Consortium also did not conduct a post-cycle survey for each of the cycles in those rounds. See here for details on which post-cycle surveys were conducted in 2021, the most recent year of surveys.

    Large-scale programs Malaria Consortium has supported with GiveWell-directed funds include:

    • Burkina Faso, Chad, and Nigeria, since 2017. See Malaria Consortium, Financial summary, September 2017 for 2017, and see here for 2018-2021.
    • Mozambique and Togo since 2020. See here. The Mozambique SMC season spans calendar years, so though spending was incurred in 2020, we did not see coverage results until 2021. "The SMC pilot in Mozambique applies the standard SMC implementation model that has been tried and tested in the Sahel. Four monthly SMC cycles consisting of three-day courses of SPAQ were delivered door-to-door to children 3–59 months by community distributors during the peak malaria season, which in northern Mozambique lasts from November to February. Unlike in west and central Africa, SMC implementation activities in Mozambique, therefore, do not align with the calendar year.” Malaria Consortium’s seasonal malaria chemoprevention program: Philanthropy report 2020, p. 27.

    Malaria Consortium started conducting post-cycle surveys in 2017 in order to determine whether surveys conducted closer to the time of SMC delivery would yield different coverage rates than surveys conducted at the end of the round (four or more months after the first SMC cycle of the season) and to identify and respond to program delivery issues during SMC campaigns.

    • "In 2017, due to concern about methodology and especially linked to potential recall bias, we reorganized the framework as a series of 4 surveys post each cycle." Diego Moroso, Regional Project Director for ACCESS-SMC at Malaria Consortium, email to GiveWell, May 8, 2018.
    • "In previous years, only one coverage survey was conducted at the end of the annual SMC round to measure coverage achieved by Malaria Consortium’s SMC program. This meant that administrative data had to be relied on to gauge coverage while the campaign was ongoing. As gathering and compiling administrative data is a time-consuming process, this limited the program’s capacity to take evidence-based corrective action and make adaptations to the intervention during the campaign. For this reason, Malaria Consortium decided to implement coverage surveys following each of the four SMC cycles in each of the three implementation countries." Malaria Consortium, 2018 SMC Coverage Report, Pg. 12.
    • "End-of-cycle (EoC) surveys employing the lot quality assurance sampling methodology following cycles 1 to 3 to enable implementing teams to identify areas of low coverage and rapidly take corrective actions to improve SMC delivery in subsequent cycles."

    • "End-of-cycle (EoC) surveys employing the lot quality assurance sampling methodology following cycles 1, 2, and 3 (where possible) to enable implementing teams to identify areas of low coverage and other issues in SMC delivery, and to rapidly take corrective actions to improve SMC delivery in subsequent cycles." Malaria Consortium, 2021 coverage report, p. 6.
    • "LQAS surveys are a comparatively simple and operationally feasible way of collecting data from randomly selected supervision areas and are designed to assess whether or not the minimum expected coverage of 80% was achieved. Aggregating data at the national or state level results in a reasonably precise measure of coverage." Malaria Consortium, Summary Narrative Report 2018, Pg. 8.
    • This approach is intended to be quicker and cheaper than typical coverage surveys, as data collectors receive less training and ask fewer questions at each household. Malaria Consortium told us that it expected to use the post-cycle results to identify and respond to implementation issues. "An LQAS framework can be done quickly by personnel with basic training, using low inputs. Results from such enquiries can be generated in real­ time through less complex analysis. In other words, LQAS is a valid sampling approach for rapid surveys, which offers managers action ­oriented information on the spot...The proposed monitoring framework combines the advantages of both approaches. The plan would be to carry out a LQAS survey at the end of Cycles 1, 2 and 3...and then to deploy a full coverage survey at the end of Cycle 4. This methodology offers the advantage of 1) quick classification of defined supervision areas in real time, to address implementation issues as they arise and improve performance, and 2) the opportunity for independent surveyors to assess coverage with an acceptable margin of error." Diego Moroso, Regional Project Director for ACCESS-SMC at Malaria Consortium, email to GiveWell, May 8, 2018.

    “In the context of public health programs such as SMC, LQAS subdivides program implementation areas into smaller functional areas (e.g. wards or health facility catchment areas) referred to as ‘supervision areas’ (SAs). The LQAS method requires a relatively small sample per SA to allow for a hypothesis test of whether a predetermined standard for a particular indicator (e.g. percentage coverage) has been met in a given SA. Although this limits interpretation of findings at the SA level, the smaller sample size allows for surveys to be rapidly completed to inform actions for program improvements (i.e. between monthly SMC cycles.” Malaria Consortium, 2021 coverage report, p. 15.

    For example: “In each compound, after obtaining consent from residents for participation in the survey, a roster of all children 3–119 months was made in SurveyCTO, and their first name, age, and sex recorded. One child 3–59 months was automatically selected at random from the roster by SurveyCTO. All questions relating to coverage related to that child, and all other questions to that child’s primary caregiver. An additional child 60–119 months was also randomly selected, if present, to allow for estimation of summary statistics for the proportion of overage ineligible children who received day 1 SPAQ in each country and Nigerian state.” Malaria Consortium, 2020 SMC coverage report, Burkina Faso, Chad, Nigeria, Togo, Pg. 18.

    • For example: "Generic questionnaires for both types of survey were initially developed in English for Nigeria and translated into French for use in Burkina Faso, Chad, and Togo. Malaria Consortium staff in each country then made minor adaptations to the questionnaires according to the specific context, for example by changing terminology used to reflect differences in local administrative units, local usage of French, or program terminology."

    Caregivers report on four or five cycles of SMC, with three days of administration in each cycle.

    In some cases, post-round surveys have been delayed, lengthening the recall period for responses. This was the case for the 2018 and 2019 post-round surveys in Chad and the 2021 post-round survey in Burkina Faso, all of which were conducted three months after the end of the relevant SMC rounds.

    • "For example, in Chad...finding an external firm to coordinate the EoR survey took much longer than expected, resulting in the survey only being conducted in January 2019, several months after the end of the 2018 SMC round. This is much later than recommended for coverage surveys and increases the risk of recall bias." Malaria Consortium, 2018 SMC Coverage Report, Pg. 20.
    • "It was also problematic in Chad, where the EoR survey was only conducted in January due to challenges in engaging a suitable supplier." Pg. 41, Malaria Consortium, 2019 coverage report.
    • “Recall bias is likely to increase along with time between the completion of cycle four SMC distribution and the beginning of EoR surveys. It should be noted, however, that time between the end of cycle four and the EoR surveys was shorter in 2020 than in previous years. For example, in 2020, EoR surveys took place in Chad during November in 2020, while the 2019 EoR survey took place in January 2020.” Malaria Consortium, 2020 SMC coverage report, Burkina Faso, Chad, Nigeria, Togo, Pg. 47.

    • Our understanding is that CDs are expected to record the first dose of each cycle and the date they gave the dose on a family's record card and that the family is expected to record all other doses. We have seen a few versions of templates for SMC record cards. One version that we have seen (from 2016) is here: SMC Record Card Template 2016.
    • For example: "Does the child have an SMC card? (Yes or No)...Ask to see blister: present? (Y or N)...Are there tablets remaining in the blister?" Malaria Consortium, 2018 end-of-round survey report, Nigeria, Pgs. 54-57.

    Card retention in Burkina Faso was 88% in 2017, 81% in 2018, 68% in 2019, and 60% in 2020; in Chad, it was 44% in 2017, 70% in 2018, 62% in 2019, and 70% in 2020; in Nigeria, it was 30% in 2017, 37% in 2018, 68-90% in 2019, and 71% in 2020; in Togo, it was 41% in 2020. (We chose not to review these rates for 2021 because Malaria Consortium reported that retention was consistently low across most areas where SMC was delivered.) We don't know why retention rates vary so widely between years and countries.

    • For card retention in 2017 and 2018, see this spreadsheet, sheet "Results: Analysis (2015-2021)," rows 73 and 127.
    • Card retention in 2019: "According to data obtained by EoR data collectors from SMC Child Record Cards, in Burkina Faso 3,251 of 4,896 children sampled, or 67.9% (95% CI: 61.2–74.0; weighted data from 23 health districts) had record cards…In Chad, SMC Child Record Cards were found for 1,634 of 2,620 children, or 62.4% (95% CI: 60.5–64.2) of the sample with available data…In Nigeria, the weighted proportions of children with SMC Child Record Cards ranged from 67.8% (95% CI: 64.7–70.8) in Sokoto to 90.0% (95% CI: 82.4–96.7) in Yobe." Malaria Consortium, 2019 coverage report, Pg. 30.
    • Card retention in 2020: “Finally, we did not consider use of SMC child record cards for estimation of coverage due to the high proportion of eligible children for whom cards were missing; it was found that 59.8 percent of eligible children in Burkina Faso, 69.3 percent in Chad, 71.2 percent in Nigeria, and 40.7 percent in Togo had SMC child record cards, based on EoR survey data. SMC child record cards may not represent a reliable source of coverage data where retention and completion are poor due to potential for bias in estimates of SMC coverage.” Malaria Consortium, 2020 SMC coverage report, Burkina Faso, Chad, Nigeria, Togo Pg. 47-48.
    • Card retention in 2021: "Although coverage can also be calculated on the basis of SMC child record cards, which are given to caregivers by community distributors the first time they administer SPAQ to a child each season, their retention by caregivers has been consistently low across most areas where SMC is delivered. Moreover, information recorded by caregivers on day 2 and day 3 AQ doses administered to children at home after distributor visits may be inconsistent. As in 2020, SMC child record cards were not employed to measure coverage for the purposes of this report." Malaria Consortium, 2021 coverage report p. 14.

    With no SMC card present, it is more difficult to check caregivers' responses. We note, however, that in the 2017 coverage surveys, which reported on the percentage of children for whom caregiver responses agreed with SMC cards, coverage rates measured from these sources were generally similar, with agreement ranging from 86% to 99%. See this spreadsheet, sheet "Methods (2015-2018)," column "Percentage of children for whom caregiver report agrees with SMC card."

    In past surveys, the greater of the number of doses noted on the SMC card or reported by the caregiver was recorded as the number of doses the child received; since 2018, Malaria Consortium has primarily used caregiver responses to measure coverage, due to low retention of SMC cards.

    • "SMC record cards greatly improve accuracy. However, caregivers do not always retain the cards; in these cases caregiver recall is the only source of information. In addition, SMC record cards are not always fully completed by health workers, meaning that the cards are not necessarily reliable. To mitigate the problem of unreliability, ACCESS-SMC researchers ask the caregiver to remember the number of treatments their child had without looking at the record card, then check the caregiver's answers against the card. Agreement has been generally good but where there is a discrepancy the interviewer tries to resolve this; if this cannot be done, the number of treatments indicated on the card is used unless the caregiver states a larger number, in which case the caregiver’s report is used, as it is known that cards can be under-completed." GiveWell's non-verbatim summary of a conversation with Paul Milligan and Diego Moroso, August 2, 2017, Pg. 5.
    • "In 2018, we only reported self-reported coverage. No adjustments/reconciliations were made. Data on SMC card retention and coverage according to SMC cards is available...but we believe that due to low retention rates, self-reported coverage is the most meaningful indicator." Malaria Consortium, comments on a draft of this page, October 2019.
    • "Coverage can also be calculated on the basis of SMC Child Record Cards, which are given to caregivers by community distributors the first time they administer SPAQ to a child each season. Caregivers are then asked to record administration of AQ doses 2 and 3 and to retain the card. Caregivers should produce the card during subsequent cycle visits and information on the card is updated. In previous years, it has been observed that SMC Child Record Cards have represented an unreliable data source, as their retention by caregivers can be low in some areas, and information recorded by caregivers on doses administered to children at home after distributor visits may be inconsistent…While this report gives consideration to data from SMC Child Record Cards as a method for estimating coverage, this will be presented as a secondary coverage indicator." Malaria Consortium, 2019 coverage report, Pg. 13.

    In 2017, some coverage surveys also gathered data on the proportion of caregivers who had retained the blister pack that contained the SMC drugs, another possible check on caregivers' responses. However, in most of the examples we've seen, a substantial number of caregivers did not retain the blister packs:

    Our understanding is that the coverage surveys from 2018 on measured but did not report on the proportion of caregivers who had retained blister packs; we have not requested this information.

    We are aware of two cases in which individuals or organizations involved in the surveys were also involved in SMC delivery. In Nigeria in 2018, post-cycle surveys were conducted by data collectors recruited by state-level health authorities, who also implemented SMC, and these data collectors may have non-randomly selected villages to survey. This may have biased data collection in two ways: (1) data collectors may have been influenced to report more positive results, and (2) because data collectors were knowledgeable about how SMC was delivered, they may have chosen to survey villages that were more likely to have received SMC. This may have biased the coverage estimates produced by these post-cycle surveys upward.

    In 2021, the post-round survey in Uganda was conducted by Malaria Consortium due to cost and capacity constraints with local consultants. Because the survey was implemented by the same organization that implemented the program, we believe that this could create an incentive for the survey to report positively on program outcomes. We note that we have seen no evidence of bias in survey results, and—as noted above—we do not focus on these results in this review or in our estimate of the cost of delivering SMC to a child due to our assumption that these results are not generalizable to future years.

    • "In 2018, post-cycle coverage was found to be consistently above 90%, often hovering very close to 100% in all states. However, post-cycle survey results should be interpreted with caution, as several methodological issues were documented and there were concerns over researchers being recruited from among state-level health authority staff. The post-round coverage survey found generally lower coverage figures, ranging from 92% in Katsina to 95% in Jigawa, which is likely a better reflection of actual coverage." Malaria Consortium, Summary Narrative Report 2018, Pgs. 7-8.
    • "The main challenge related to researchers being selected by political LGA authorities. This increases safeguarding risk and may introduce bias because state authorities have a vested interest in reporting positive implementation results. Another limitation arises from researchers’ familiarity with implementation plans. If frontline implementers focus on “easy-to-reach” areas within a supervision area (the unit of randomization) and researchers, aware of implementers’ activities, simply follow in their footsteps, this may lead to an overestimation of coverage." Malaria Consortium, Summary Narrative Report 2018, Pg. 9.
    • "In Nigeria, EoC surveys were carried out by data collectors recruited through state- or LGA-level health authorities, which raises concerns about the impartiality of data collectors, as their employers would have a stake in implementing a successful SMC campaign. There were also concerns that the data collectors, being familiar with the SMC campaign, may have selected villages they knew had been covered by drug distributors." Malaria Consortium, 2018 SMC Coverage Report, Pg. 20.

    Malaria Consortium reports that in Chad, the 2018 post-cycle surveys and the first 2019 post-cycle survey were of low quality; issues were not mentioned in 2020 or 2021.

    • "Chad: The quality of outputs from some of the selected research firms was unsatisfactory and required Malaria Consortium to carry out additional, time-consuming analyses. Despite outsourcing post-cycle surveys to different firms each cycle, deliverables did not meet our expectations, leading us to conclude that local research firms do not have the required capacity and expertise to conduct complex evaluations of coverage and quality." Malaria Consortium, Summary Narrative Report 2018, Pg. 9.
    • "We therefore decided to rely on independent surveys conducted by third parties. However, it should be noted that this may pose different challenges. This was particularly the case in Chad, where capacity of local research firms to execute large-scale surveys is relatively low. Due to inability to engage a suitable contractor no cycle 2 EoC survey was carried out. The EoR survey was also delayed as it was necessary to contract the same research firm from Burkina Faso which also conducted that country’s EoR survey." Malaria Consortium, 2019 coverage report, Pg. 41.
    • "What caused you to determine that the quality of coverage data from the first post-cycle survey in Chad was poor?...Data collection for the first end-of-cycle survey was slow and a succession of draft reports were incomplete with essential information missing. When reviewing the raw dataset, it was noted that it did not correspond exactly to the survey codebook, which may have been a result of mislabelling of variables. In addition, some variables were missing altogether. The local company that conducted the survey following cycle 3 provided better quality work and the regional firm that was commissioned for the end-of-round survey was very good."

    • For Nigeria in 2018, Malaria Consortium proposes three possible explanations for the inconsistent results: "Again, the EoR survey found slightly lower coverage in Nigeria...This difference could be a result of recall bias, data collectors’ bias or it could be due to questionnaire design." Malaria Consortium, 2018 SMC Coverage Report, Pgs. 22-23. Of these, it appears that bias during data collection may have contributed most to skewing post-cycle results upward:
      • "In 2018, post-cycle coverage was found to be consistently above 90%, often hovering very close to 100% in all states. However, post-cycle survey results should be interpreted with caution, as several methodological issues were documented and there were concerns over researchers being recruited from among state-level health authority staff. The post-round coverage survey found generally lower coverage figures, ranging from 92% in Katsina to 95% in Jigawa, which is likely a better reflection of actual coverage." Malaria Consortium, Summary Narrative Report 2018, Pgs. 7-8.
      • "The main challenge related to researchers being selected by political LGA authorities. This increases safeguarding risk and may introduce bias because state authorities have a vested interest in reporting positive implementation results. Another limitation arises from researchers’ familiarity with implementation plans. If frontline implementers focus on “easy-to-reach” areas within a supervision area (the unit of randomization) and researchers, aware of implementers’ activities, simply follow in their footsteps, this may lead to an overestimation of coverage." Malaria Consortium, Summary Narrative Report 2018, Pg. 9.
    • For Nigeria in 2019-2021, our best guess is that post-round results are again a better indication of actual coverage. In 2019, post-cycle results were 34% higher than post-round results and were surprisingly high (around 95% or higher coverage, see here), which makes us concerned that there may have been issues in post-cycle survey implementation in Nigeria that Malaria Consortium has not identified and that biased results upward. This difference has decreased in subsequent years (14% in 2020; 5% in four-cycle states and 8% in five-cycle states in 2021) but has remained higher than the difference in other countries. See here, rows 195, 249, and 305.
    • According to Malaria Consortium, these discrepancies often result from large discrepancies in specific states. In 2020, Malaria Consortium noted: “Fourth, while results of EoC and EoR surveys were relatively consistent in Burkina Faso and Chad, this was not the case for some Nigerian states (particularly in the states of Kano, Sokoto, and Yobe), where there were significant differences in estimates for some indicators (e.g. day 1 SPAQ coverage among eligible children) in 2020 and in 2019. Efforts will be made to determine whether these differences represent a trend in coverage during the SMC round, or instead are a result of differences in quality or representativeness of EoC surveys compared with EoR surveys; if the latter, appropriate actions will be taken to ensure the representativeness of EoC surveys in 2021 and beyond.” Malaria Consortium, 2020 SMC coverage report, Burkina Faso, Chad, Nigeria, Togo Pg. 48. In 2021, Malaria Consortium noted that Bauchi and Sokoto states in Nigeria had the widest discrepancies in post-cycle and post-round results: "... data have recently been obtained on populations by village for Kebbi, Bauchi, and Sokoto (the latter two having the widest discrepancies between EoC and EoR results)..." Malaria Consortium, 2021 coverage report, p. 57.
    • For Chad in 2019, our best guess is that post-round results are a better indication of actual coverage. Post-cycle surveys were conducted after the first and third SMC cycles in Chad in 2019. Malaria Consortium reports that the first post-cycle survey in Chad was of poor quality, so we have limited confidence in the reliability of those results. The third post-cycle survey found coverage of around 98%, which we find implausibly high.

    An additional consideration is that Malaria Consortium told us that it places more weight on post-round results, as post-round surveys are explicitly designed to achieve representative samples, whereas post-cycle surveys are designed to assess whether each program area unit met a target coverage level (see discussion above). This understanding is from Malaria Consortium, conversation with GiveWell, August 20, 2020 (unpublished).

    More detail on the methods is given as follows: "The relative reduction in the number of malaria cases and malaria deaths under five years of age, compared to older age groups, observed when SMC was introduced, was estimated from the number of confirmed cases of deaths in-hospital that were reported in the national Health Management Information Systems, supplemented by data on malaria cases collected from clinic registers in selected health facilities in each country."

    • "As part of the Unitaid funded 2015-17 Achieving Catalytic Expansion of Seasonal Malaria Chemoprevention in the Sahel (ACCESS-SMC) program, which was led by Malaria Consortium, Milligan et altera from the London School of Hygiene and Tropical Medicine conducted an impact assessment, which explored malaria cases and deaths using reported data from national Health Management Information Systems (HMIS) and sentinel sites (Milligan, 2018). Data abstracted from sentinel sites showed that the estimated average reduction of malaria cases in 2015 and 2016 were 41% and 49% in Burkina Faso; 37% and 25% in Chad; 25% and 25% in Nigeria, respectively."

    • "Data for impact indicators outlined in Table 1 were abstracted from the national HMIS over the years of 2013 to 2018 for Burkina Faso and Chad, and 2017 to 2018 for Nigeria and were retrospectively analysed." Malaria Consortium, 2019 impact report, Pg. 4.
    • "To generate estimates of the level of impact of SMC, a Poisson regression model was fitted to the number of cases confirmed by RDT or microscopy reported to health facilities during the SMC distribution months (August, September, October, November) between 2013 and 2018 (or 2017-2018 for Nigeria)."

    "Analysis of HMIS data at the national level for each country overall showed no evidence of impact." Malaria Consortium, 2019 impact report, Pg. 9.

  • 110
    • "A review of the quality of HMIS data for each country was conducted, which showed varied results between and within countries...Checks for data completeness were conducted for each country, as defined by the proportion of all monthly reports for each indicator available. Briefly, Burkina Faso showed high completeness of data with less than 1% of missing data points for the relevant indicators. Data coming from Chad and Nigeria showed low completeness ranging from 36- 42%. To mitigate potential bias from low completeness, any health facility or district with more than 1 month missing data during the SMC distribution period was excluded...Further checks for data accuracy revealed data entry errors as well as major health data reporting issues. First, common in all countries were obvious data entry errors most likely due to typing errors, entering data into the incorrect field, recording data in the wrong month, etc. The level of data accuracy varied across and within countries. Additionally, the analysis also revealed major data reporting issues that bring into question the overall accuracy of data that is captured in the national HMIS. For example, in Burkina Faso, approximately 30% of the data points reported more malaria cases in children under 5 than there were children seen that month." Malaria Consortium, 2019 impact report, Pg. 7.
    • "However, as previously discussed, the quality of data, the limitations of HMIS data reporting, and the inability to adjust for major factors affecting malaria transmission contribute to noise in the analysis and result in inaccurate estimates of effect...With regards to quality of impact data, in this analysis, we sought to analyse impact indicators available through the national HMIS from Burkina Faso, Chad, and Nigeria. Overall, the analysis indicated that accurate health data reporting is still a point of improvement for health systems and limitations to the data must be considered when interpreting results from national HMIS. Inaccurate data with no means of verification contribute to noise in the analysis and result in either dampening or amplification of estimated effects." Malaria Consortium, 2019 impact report, Pg. 9.

  • 111
    • "While we are aware of the limitations of HMIS data and we have started using other sources of data to determine impact, we will continue to analyse HMIS data for 2 reasons: 1) It is commonly used by governments and bilateral/multilateral organisations to track progress/impact of health programmes; 2) in the long-term, it is the most sustainable/affordable source of impact data and we aim to contribute to strengthening HMIS in the long run." Malaria Consortium, comments on a draft of this page, October 2019.
    • "It’s really about sustainability. We aim to avoid creating new or parallel systems wherever possible. In the longer-term, HMIS should serve as the main source for impact data for health programmes. Surveys, cohort studies etc. are expensive and not sustainable as a routine source of impact data. We see it as part of our remit to contribute to the strengthening of existing health system structures and we will continue to use HMIS data for our analyses." Malaria Consortium, comments on a draft of this page, October 2020.

    • "Efficacy of SMC treatments will be measured using the case control approach. Malaria cases, and controls who do not have malaria, will be recruited concurrently, and the dates of the doses of SMC they received noted. The efficacy of SMC can then be calculated as a function of the time since treatment using case-control analysis. It is essential that dates of SMC doses are accurately documented, and that malaria cases are parasitologically confirmed. Controls will be selected from the community, in the neighbourhood where the case lived at the time they had malaria. Trained fieldworkers will collect information about cases and controls, and make home visits to record bednet use and other household factors that may act as confounders. Microscopy will be used to confirm cases and to measure parasite density. Controls will be confirmed to be negative for P.falciparum, by RDT."

    • "Resistance to sulfadoxine-pyrimethamine (SP) and amodiaquine (AQ) is associated with specific gene mutations in the malaria parasite. Monitoring the prevalence of these markers, in malaria cases health facilities and in P. falciparum carriers in the general population, permits early warning of emerging problems with drug resistance. This progress update is on monitoring P. falciparum resistance markers. The objective of the molecular monitoring through the ACCESS-SMC project was to establish a baseline for monitoring the prevalence of the markers across the subregion using standardised methods, and to determine if there have been any important changes in the prevalence of these markers after two years of SMC at scale. [...] The baseline surveys were done at the end of the 2015 transmission season in all seven countries. (In 6 countries, sampling was done in areas which had not started SMC but would implement the following year. In The Gambia, sampling was in an area where SMC had been implemented for two years). In each country, one locality was chosen, blood samples were collected from approximately 2000 children under 5 years of age and 2000 individuals 10-30 years of age per country, taken onto filter paper and shipped to London to the LSHTM laboratories for analysis. The older age group was included because they would not be treated with SMC drugs, assessment of trends in the prevalence of markers of resistance in this group therefore allows us to determine whether SMC is leading to changes in the circulating parasite population."

    • "Thus overall, mutations associated with amodiaquine resistance have not increased in prevalence and the prevalence of the combination pfmdr1-86Y with pfmdr1-184Y occurred with a prevalence of 1.6% and the combination of pfmdr1-86Y and pfmdr1-184Y with pfcrt-CVIET occurred with a prevalence of 0.89% in the 10-30 year age group. The mutations associated with resistance to SP, increased in prevalence between 2016 and 2018. In the 10-30 year age group the prevalence of the dhfr triple mutation increased from 81% to 90%, and the overall prevalence of the dhps 540E mutation increased almost 5-fold."

    "The most common reaction seen with SMC drugs during the pilot studies and during the first year of ACCESS-SMC was regurgitating the drug after ingestion. This was due to the unpleasant and lasting bitter taste of amodiaquine and because the hard tablets were not always crushed into a fine powder before mixing with water, which often caused children to gag and expel the medicine. Since the introduction of the orange flavored dispersible amodiaquine and SP tablets, this is no longer a common problem." Malaria Consortium, comments on a draft of this page, October 2017

    • In this spreadsheet, we calculate cost per SMC cycle administered for Burkina Faso, Chad, and Nigeria.
    • We do not calculate this figure for Togo (from which we have expenditure and coverage data from 2020-2021) because we do not have information about the costs contributed by the Global Fund and UNICEF to this program, which co-fund SMC delivery in the districts in Togo that Malaria Consortium also supports. See Table 11: SMC target population by funding source, Togo 2020-2021, Malaria Consortium’s seasonal malaria chemoprevention program: Philanthropy report 2021, Pg. 36.
    • In our SMC cost-effectiveness analysis, we use the weighted average cost per SMC cycle administered for Burkina Faso, Chad, and Nigeria as our estimate for the cost per SMC cycle administered in Togo.
    • We do not calculate this figure for Mozambique and Uganda (from which we have expenditure and coverage data from 2021). Malaria Consortium was operating at a small scale and doing implementation research in these countries in 2021, so we don't expect this data to provide a good indication of the cost per SMC cycle administered that Malaria Consortium might achieve in future program years.

    • In April 2014-March 2015, it appears that about 11% of Malaria Consortium's total expenditure was unrestricted. See "Resources expended" from 2015 and compare "Restricted funds" and "Total funds" columns on Malaria Consortium, Trustees' report and financial statements 2015, Pg 17. Percentage of spending coming from restricted funds calculation: 50,626,000 British pounds / 56,809,000 British pounds = 0.89.
    • In April 2015-March 2016, it appears that about 14% of Malaria Consortium's total expenditure was unrestricted. See Malaria Consortium, Trustees' report and financial statements 2016, Pg 16. (Math: On the line "Total Expenditure", 5886/41189 = 0.143.)
    • In April 2016-March 2017, it appears that 12% of Malaria Consortium's total expenditure was unrestricted. See Malaria Consortium, Trustees' report and financial statements 2017. (Math: On the line "Total Expenditure", 5,900/50,840 = 0.116.)
    • Malaria Consortium told us that it often uses unrestricted funding to support overhead that is needed for some of the restricted grants it receives (sometimes funders' requirements do not allow it to spend on overhead), so these unrestricted funds are not available to support new programs and activities. GiveWell's non-verbatim summary of conversations with Malaria Consortium staff, November 7 and November 9, 2016.
    • For a more detailed breakdown of how Malaria Consortium has spent unrestricted funds in the past, see Malaria Consortium, restricted and unrestricted expenditure analysis 2016. It seems possible that some of the funds spent on "Monitoring & surveillance of malaria" and "Malaria strategy support" supported aspects of SMC programs, but we are uncertain.
    • Malaria Consortium told us that it agrees with the U.K. Department for International Development about how it will use Programme Partnership Agreement (PPA) funds. It told us that it decides which programs to apply for PPA funds with depending on what it believes will be most impactful, and then if it receives PPA funds it is committed to spending the funds on those programs. GiveWell's non-verbatim summary of conversations with Malaria Consortium staff, November 7 and November 9, 2016.
    • Malaria Consortium told us that it does not expect to receive PPA funds beyond 2018 due to the discontinuation of this funding stream for all recipients by the UK government. GiveWell's non-verbatim summary of conversations with Malaria Consortium staff, November 7 and November 9, 2016.
    • In 2018, Malaria Consortium told us that it has not allocated significant amount of unrestricted funding to either SMC programs or other program activities in the last year. Diego Moroso, Malaria Consortium Global Programme Director - SMC, email to GiveWell, July 31, 2018.
    • Malaria Consortium told us in July 2019 that it did not have sufficient unrestricted funding from the prior year to allocate unrestricted funding to SMC (Christian Rassi, Malaria Consortium SMC Programme Director, email to GiveWell, July 31, 2019). It did allocate at least $100,000 of unrestricted funding to projects other than SMC (Madeleine Marasciulo, Malaria Consortium US Development Lead, conversation with GiveWell, March 4, 2019). This funding was from Malaria Consortium's US entity. Our guess is that a large portion of this funding was from donors who read our recommendation of Malaria Consortium's SMC program and gave to Malaria Consortium unrestricted, either intentionally or unintentionally. This is our guess based on Malaria Consortium noting (Madeleine Marasciulo, Malaria Consortium US Development Lead, email to GiveWell, February 22, 2019) that it has seen its unrestricted donations to its US entity increase from a very low level since GiveWell began recommending Malaria Consortium's SMC program as a top charity.
