Clinical Trial Summary

Seasonal malaria chemoprevention (SMC) is a new strategy recommended by World Health Organization in 2012 for areas of highly seasonal transmission such as the Sahel. Although randomized controlled trials have shown SMC to be highly effective, evidence and experience from routine implementation of SMC has been lacking. For these reasons, we conducted a comprehensive evaluation of the coverage, adherence, and impact of SMC on malaria infection and disease and anemia when delivered through routine programs using existing community health workers in the Kayes region in Mali. Our evaluation used a pre-post design with cross-sectional surveys and abstraction of routine health information system data in an intervention district (Kita) where SMC was implemented through the health system, and a comparison district (Bafoulabe) where SMC was not implemented.


Clinical Trial Description

Seasonal malaria chemoprevention (SMC) is a new strategy recommended by World Health Organization in 2012 for areas of highly seasonal transmission such as the Sahel. Although randomized controlled trials (RCTs) have shown SMC to be highly effective, evidence and experience from routine implementation of SMC has been lacking. For these reasons, we conducted a comprehensive evaluation of the coverage, adherence, and impact of SMC on malaria infection and disease, and anemia when delivered through routine programs using existing community health workers in the Kayes region in Mali. A pre-post design was used, with one intervention district, Kita where four rounds of SMC with Sulfadoxine-Pyrimethamine plus Amodiaquine (SP+AQ) took place in August-November 2014, and one comparison district, Bafoulabe. Cross-sectional surveys were carried out in children aged 3-59 months from 30 randomly selected localities (15/district) at baseline and in follow-up to assess the impact of SMC on malaria parasitemia, fever, malaria illness, and anemia. The baseline survey was performed in July 2014 prior to the start of SMC implementation and the post-intervention (follow-up) surveys took place in December 2014. Blood samples were collected for thick/thin smears for malaria and hemoglobin measurement in two cross-sectional surveys, one prior to SMC in July 2014 and one after SMC in December 2014. The impact on malaria morbidity was assessed using routine data on confirmed malaria cases extracted from the registers by the research team in nine of the 47 community health centers in Kita and seven of the 24 health centers in Bafoulabe. Cross-sectional surveys were also carried out about 7 days after each of the four rounds of SMC to assess caregivers' adherence to the administration of SMC drugs and determine the frequency of adverse events in the intervention district of Kita. Coverage was assessed by cross-sectional in children 3-59 months in 30 randomly selected clusters in the district of Kita using interview of the caregivers and information on the SMC card in December 2014. ;
