A Cluster Randomized Trial of Delivery of Intermittent Preventive Treatment of Malaria in Pregnancy at the Community Level in Malawi

Abstract

Background Malaria in pregnancy doubles the risk of low birthweight and causes 11% of all neonatal deaths in sub-Saharan Africa. To prevent these and other adverse health consequences, the World Health Organization recommends administering intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine–pyrimethamine for all pregnant women at each antenatal care (ANC) visit, starting as early as possible in the second trimester. The target is for countries to administer a minimum of three doses (IPTp3+) to at least 85% of pregnant women. Methods A cluster randomized, controlled trial was conducted to assess the effect of delivery of IPTp by community health workers on the coverage of IPTp3+ and ANC visits in Malawi. Community delivery of IPTp was implemented within two districts in Malawi over a 21-month period, from November 2018 to July 2020. In control sites, IPTp was delivered at health facilities. Representative samples of women who delivered in the prior 12 months were surveyed at baseline (n=370, December 2017) and endline (n=687, August 2020). A difference in differences analysis was conducted to assess the change in coverage of IPTp and ANC over time, accounting for clustering at the health facility level. Results Overall IPTp coverage increased over the study period. At baseline, women received a mean of 2.3 IPTp doses (range 0–5 doses) across both arms, and at endline, women received a mean of 2.8 doses (range 0–9 doses). Despite overall increases, the change in IPTp3+ coverage was not significantly different between intervention and control groups (6.9%, 95% CI: -5.9%, 19.6%). ANC4+ coverage increased significantly in the intervention group compared with the control group, with a difference-in-differences of 25.3 percentage points (95% CI: 1.3%, 49.3%). Conclusions In order to reduce the burden of malaria in pregnancy, new strategies are needed to improve uptake of effective interventions such as IPTp. While community health workers’ delivery of IPTp did not increase uptake in this study, they may be effective in other settings or circumstances. Further research can help identify the health systems characteristics that are conducive to community delivery of IPTp and the operational requirements for effective implementation.

Systematic Review: Prevalensi dan Dampak Infeksi Malaria pada Wanita Hamil dan Neonatal

“…24 Manajemen malaria pada wanita hamil signifikan dapat mengurangi risiko maternal anemia diantaranya dengan melakukan pemeriksaan ANC secara rutin untuk memantau kondisi ibu dan janin, penggunaan kelambu berinsektisida untuk mencegah gigitan nyamuk, 27 pemeriksaan Hb secara rutin sebulan sekali dan pemberian tablet zat besi selama kehamilan, 28 asam folat, pemberian chloroquine pada kunjungan pertama ANC sampai dengan masa nifas, efektivitas pemberian tiga dosis sulfadoxine pyrimethamine yang direkomendasikan WHO terbukti efektif untuk mencegah malaria selama kehamilan. 29,30,31…”
