Background To prevent child deaths from severe malaria, early parenteral treatment is essential. Yet, in remote rural areas, accessing facilities offering parenteral antimalarials may be difficult. A randomised controlled trial found pre-referral treatment with rectal artesunate (RAS) to reduce deaths and disability in children who arrived at a referral facility with delay. This study examined the effectiveness of pre-referral RAS treatment implemented through routine procedures of established community-based health care systems. Methods An observational study accompanied the roll-out of RAS in the Democratic Republic of the Congo (DRC), Nigeria and Uganda. Children <5 years of age presenting to a community-based health provider with a positive malaria test and signs of severe malaria were enrolled and followed up during admission and after 28 days to assess their health status and treatment history. The primary outcome was death; covariates of interest included RAS use, referral completion, and post-referral treatment. Results Post-roll-out, RAS was administered to 88% of patients in DRC, 52% in Nigeria, and 70% in Uganda. The overall case fatality rate (CFR) was 6.7% (135/2011) in DRC, 11.7% (69/589) in Nigeria, and 0.5% (19/3686) in Uganda; 13.8% (865/6286) of patients were sick on day 28. The CFR was higher after RAS roll-out in Nigeria (16.1 vs. 4.2%) and stable in DRC (6.7 vs. 6.6%) and Uganda (0.7 vs. 0.3%). In DRC and Nigeria, children receiving RAS were more likely to die than those not receiving RAS (aOR=3.06, 95% CI 1.35–6.92 and aOR=2.16, 95% CI 1.11–4.21, respectively). Only in Uganda, RAS users were less likely to be dead or sick at follow-up (aOR=0.60, 95% CI 0.45–0.79). Post-referral parenteral antimalarials plus oral artemisinin-based combination therapy (ACT), a proxy for appropriate post-referral treatment, was protective. However, in referral health facilities, ACT was not consistently administered after parenteral treatment (DRC 68.4%, Nigeria 0%, Uganda 70.9%). Conclusions Implemented at scale to the recommended target group, pre-referral RAS had no beneficial effect on child survival in three highly malaria-endemic settings. RAS is unlikely to reduce malaria deaths unless health system issues such as referral and quality of care at all levels are addressed. Trial registration The study is registered on ClinicalTrials.gov: NCT03568344.

IntroductionChildren who receive prereferral rectal artesunate (RAS) require urgent referral to a health facility where appropriate treatment for severe malaria can be provided. However, the rapid improvement of a child’s condition after RAS administration may influence a caregiver’s decision to follow this recommendation. Currently, the evidence on the effect of RAS on referral completion is limited.MethodsAn observational study accompanied the roll-out of RAS in three malaria endemic settings in the Democratic Republic of the Congo (DRC), Nigeria and Uganda. Community health workers and primary health centres enrolled children under 5 years with suspected severe malaria before and after the roll-out of RAS. All children were followed up 28 days after enrolment to assess their treatment-seeking pathways.ResultsReferral completion was 67% (1408/2104) in DRC, 48% (287/600) in Nigeria and 58% (2170/3745) in Uganda. In DRC and Uganda, RAS users were less likely to complete referral than RAS non-users in the pre-roll-out phase (adjusted OR (aOR)=0.48, 95% CI 0.30 to 0.77 and aOR=0.72, 95% CI 0.58 to 0.88, respectively). Among children seeking care from a primary health centre in Nigeria, RAS users were less likely to complete referral compared with RAS non-users in the post-roll-out phase (aOR=0.18, 95% CI 0.05 to 0.71). In Uganda, among children who completed referral, RAS users were significantly more likely to complete referral on time than RAS non-users enrolled in the pre-roll-out phase (aOR=1.81, 95% CI 1.17 to 2.79).ConclusionsThe findings of this study raise legitimate concerns that the roll-out of RAS may lead to lower referral completion in children who were administered prereferral RAS. To ensure that community-based programmes are effectively implemented, barriers to referral completion need to be addressed at all levels. Alternative effective treatment options should be provided to children unable to complete referral.Trial registrstion numberNCT03568344; ClinicalTrials.gov.

Background To prevent child deaths from severe malaria, early parenteral treatment is essential. Yet, in remote rural areas, higher-level facilities offering parenteral antimalarials are often difficult to access. A randomised controlled trial found pre-referral rectal artesunate (RAS) to reduce death and disability in children who delay arriving at a referral facility. This study examined the effectiveness of pre-referral RAS treatment in established community-based health care systems. Methods An observational study accompanied the roll-out of RAS in the Democratic Republic of the Congo, Nigeria and Uganda. Children < 5 years presenting to a community-based health provider with a positive malaria test and signs of severe malaria were followed-up during admission and after 28 days to assess their health status and treatment history. The primary outcome was death; covariates of interest included RAS use, referral completion, and post-referral treatment. Findings Post-roll-out, RAS was administered to 88% of patients in DRC, 52% in Nigeria, and 70% in Uganda. The overall case fatality rate (CFR) was 6.7% (135/2011) in DRC, 11.7% (69/589) in Nigeria, and 0.5% (19/3686) in Uganda; 865/6286 patients were sick at follow-up. In all countries, the CFR was higher after RAS-roll-out (6.7 vs. 6.6% in DRC, 16.1 vs. 4.2% in Nigeria, 0.7 vs. 0.3% in Uganda). In DRC and Nigeria, children receiving RAS were more likely to die than those not receiving RAS (aOR = 3.31, 95% CI 1.43-7.65 and aOR = 2.42, 95% CI 1.25-4.70, respectively). In Uganda, RAS users were less likely to be dead or sick at follow-up (aOR = 0.61, 95% CI 0.46-0.80). Post-referral parenteral antimalarials were protective in all countries; however, the effect of ACT administration was inconsistent. Interpretation RAS pre-referral treatment had no beneficial effect on child survival in three highly malaria endemic settings. RAS is unlikely to reduce malaria deaths unless health system shortfalls such as referral and post-referral treatment are addressed.

The key to reducing malaria deaths in highly endemic areas is prompt access to quality case management. Given that many severe cases occur at peripheral level, rectal artesunate (RAS) in the form of suppositories was developed in the 1990s, allowing for rapid initiation of life-saving antimalarial treatment before referral to a health facility with full case management capabilities. One randomized controlled trial published in 2009 showed a protective effect of RAS pre-referral treatment against overall mortality of 26%, but with significant differences according to study sites and length of referral. Two important issues remained unaddressed: (1) whether the mortality impact of RAS observed under controlled trial conditions could be replicated under real-world circumstances; and (2) clear operational guidance for the wide-scale implementation of RAS, including essential health system determinants for optimal impact. From 2018 to 2020, the Community Access to Rectal Artesunate for Malaria (CARAMAL) project was conducted as a large-scale observational implementation study in the Democratic Republic of the Congo (DRC), Nigeria, and Uganda (registered on ClinicalTrials.gov as NCT03568344). CARAMAL aimed to provide high-quality field evidence on the two issues above, in three remote settings with high malaria endemicity. A number of complementary study components were implemented. The core of the CARAMAL study was the Patient Surveillance System (PSS), which allowed tracking of cases of severe febrile illness from first contact at the periphery to a referral health facility, and then on to a Day 28 visit at the home of the patient. Community and provider cross-sectional surveys complemented the PSS. Here we describe in some detail RAS implementation, as well as the key CARAMAL study components and basic implementation experience. This manuscript does not intend to present key study results, but provides an extensive reference document for the companion papers describing the impact, referral process, post-referral treatment and costing of the RAS intervention.

ObjectivesThe subcutaneous depot medroxyprogesterone acetate (DMPA-SC) injectable contraceptive was introduced in South West Nigeria in 2015 through private sector channels. The introduction included community-based distribution and was supported by a social marketing approach. From program monitoring and evaluation, aimed at understanding performance, market reach and other process measures, we identify lessons learned to inform future scale-up efforts.MethodsWe synthesized the findings from a core set of key performance indicators collected through different methods: (1) implementer performance indicators, (2) phone survey of DMPA-SC users (n=541) with a follow-up after 3 months (n=342) and (3) in-depth interviews with 57 providers and 42 users of DMPA-SC.ResultsDistribution of DMPA-SC to private providers was concentrated in states with large urban populations. A shift toward focusing on high-volume family planning facilities coincided with a rapid increase in distribution in late 2016. Users reached in the phone survey were generally older and married with children; few were under age 25. Users and providers reported favorable opinions of DMPA-SC. Many users reported choosing DMPA-SC due to recommendations from providers and friends, and the hope of experiencing reduced side effects compared to other methods. While users reported positive experiences interacting with community-based distributors, the delivery model encountered a number of challenges — high turnover, low motivation, lack of an appropriate compensation package and logistical costs — and was ultimately disbanded.ConclusionsIn the DMPA-SC introductory program in Nigeria, distribution was amplified when focused on high-volume contraceptive providers. Although community-based distribution can be one effective service delivery model for reaching underserved populations, more consideration for balancing cost recovery and public health goals through private sector approaches are needed in the context of South West Nigeria. Additional communications and outreach efforts are needed to reach younger, unmarried users with contraceptive services.
