Background Mass drug administration (MDA) is one of the key interventions recommended by WHO for prevention and control of neglected tropical diseases (NTD). In Malawi, MDA is widely carried out annually since 2009 for prevention and control of schistosomiasis and soil-transmitted helminths (STH). No study has been carried out to assess effectiveness of the MDA approach and to document perceptions of health providers and beneficiaries regarding use of MDA. This study was done to understand how well MDA is being implemented and to identify opportunities for improvement in MDA delivery in Malawi. Methods Designed as a cross-sectional and multi-methods research, the study was carried out in three southern Malawi districts of Chiradzulu, Mangochi and Zomba. In each district, four health centres and 16 villages were randomly selected to participate. A mixed-methods approach to data collection focusing on quantitative data for coverage and knowledge, attitudes and practices assessments; and qualitative data for assessing perceptions of health providers and beneficiaries regarding MDA was used. Quantitative data were processed and analyzed using IBM SPSS software version 26 while qualitative data were analysed using NVivo 12 for Windows. Results Knowledge levels about schistosomiasis and STH in the districts varied according to disease aspects asked about. Majority are more knowledgeable about what schistosomiasis is (78%) and whether STH are treatable with drugs (97%); with least knowledgeable about the organism that transmits schistosomiasis (18%), types of schistosomiasis (11%) and what causes STH (20%). In 2018 and 2019 the districts registered high coverage rates for praziquantel and albendazole using community-based MDA (73–100%) and using school-based MDA (75–91%). Both the health authorities and community members perceived the MDA approach as good because it brings treatment closer to people. Conclusion With the high MDA coverage obtained in communities and schools, the effectiveness of MDA in the target districts is satisfactory. There are, however, several challenges including disproportionate knowledge levels, which are hampering progress towards attainment of the 2030 global NTD goals. There is a need for promotion of community participation and partnerships as well as implementation of other recommended interventions for sustainable prevention and control of schistosomiasis and STH.

Background Community-Directed Interventions (CDI) is a participatory approach for delivery of essential healthcare services at community level. It is based on the values and principles of Primary Health Care (PHC). The CDI approach has been used to improve the delivery of services in areas that have previously applied Community-Directed Treatment with ivermectin (CDTi). Limited knowledge is available about its added value for strengthening PHC services in areas without experience in CDTi. This study aimed to assess how best to use the CDI approach to strengthen locally identified PHC services at district level. Methods This was a comparative intervention study carried out over a period of 12 months and involving four health centres and 16 villages assigned to 1) a conventional Essential Health Package (EHP)/PHC approach at health centre level or 2) an EHP/PHC/CDI approach at community level in addition to EHP/PHC at health centre level. Communities decided which intervention components to be included in the intervention. These were home management of malaria (HMM), long lasting insecticide treated nets (LLIN), vitamin A and treatment against schistosomiasis. The outcomes of the two strategies were compared quantitatively after the intervention was completed with regard to intervention component coverage and costs. Qualitative in-depth interviews with involved health professionals, implementers and beneficiaries were carried out to determine the benefits and challenges of applied intervention components. Results Implementation of the EHP/PHC/CDI approach at community level as an add-on to EHP/PHC services is feasible and acceptable to health professionals, implementers and beneficiaries. Statistically significant increases were observed in intervention components coverage for LLIN among children under 5 years of age and pregnant women. Increases were also observed for HMM, vitamin A among children under 5 years of age and treatment against schistosomiasis but these increases were not statistically significant. Implementation was more costly in EHP/PHC/CDI areas than in EHP/PHC areas. Highest costs were accrued at health centre level while transport was the most expensive cost driver. The study identified certain critical factors that need to be considered and adapted to local contexts for successful implementation. Conclusion The CDI approach is an effective means to increase accessibility of certain vital services at community level thereby strengthening delivery of EHP/PHC services. The approach can therefore complement regular EHP/PHC efforts. Trial registration The study was retrospectively registered with the Pan African Clinical Trial Registry TRN: PACTR201903883154921 .

Background Mass drug administration (MDA) is one of the key interventions recommended by WHO for prevention and control of neglected tropical diseases. In Malawi, MDA is widely carried out annually since 2012 for prevention and control of schistosomiasis and soil transmitted helminths (STH). No study has been carried out to assess effectiveness of the approach and to document perceptions of health providers and beneficiaries regarding use of MDA. This study aimed to examine perceived strengths and weaknesses, successes and failures, as well as health providers’ and beneficiaries’ perspectives of implementing the strategy in Malawi. Methods As a cross-sectional implementation research, the study was carried out in three southern Malawi districts of Chiradzulu, Mangochi and Zomba. In each district, four health centres and 16 villages were randomly selected to participate. A mixed-methods approach to data collection focusing on quantitative data for coverage and knowledge, attitudes and practices assessments; and qualitative data for assessing perceptions of health providers and beneficiaries regarding MDA was used. Quantitative data were processed and analyzed using IBM SPSS software version 26 while qualitative data were analysed using NVivo 12 for Windows. Results Knowledge levels about schistosomiasis and STH in the districts varied according to disease aspects asked about. Majority are more knowledgeable about what schistosomiasis is (78%) and whether STH are treatable with drugs (97%); with least knowledgeable about the organism that transmits schistosomiasis (18%), types of schistosomiasis (11%) and what causes STH (20%). In 2018 and 2019 the districts registered high coverage rates for praziquantel and albendazole using community-based MDA (73%-100%) and using school-based MDA (75%-91%). Both the health authorities and community members perceived the MDA approach as good because it brings treatment closer to people. Conclusion With the high MDA coverage obtained in schools and communities, the implementation of MDA in the target districts is satisfactory. There are, however, several challenges including disproportionate knowledge levels, which are hampering progress towards attainment of the 2030 global NTD goals. There is a need for promotion of community participation and partnerships as well as implementation of other recommended interventions for sustainable prevention and control of schistosomiasis and STH.

Preventive chemotherapy using mass drug administration (MDA) is one of the key interventions recommended by WHO, to control neglected tropical diseases. In Malawi, health workers distribute anti-helminthic drugs annually with most support from donors. The mean community coverage of MDA from 2018 to 2020 were high at 87% for praziquantel and 82% for albendazole, however posing a sustainability challenge once donor support diminishes. This study was conducted to compare use of the community-directed intervention (CDI) approach with the use of health workers in delivery of MDA. It was carried out in three districts, where cross-sectional, mixed-methods approach to data collection during baseline and follow-up assessments was used. Knowledge levels were high for what schistosomiasis is (65% - 88%) and what STH are (32% - 83%); and low for what causes schistosomiasis (32% - 58%), causes of STH (7% - 37%), intermediate organisms for schistosomiasis (13% - 33%) and types of schistosomiasis (2% - 26%). At follow-up, increases in praziquantel coverage were registered in control (86% to 89%) and intervention communities (83% to 89%); decreases were recorded for control (86% to 53%) and intervention schools (79% to 59%). Assessment of the costs for implementation of the study indicated that most resources were used at community (51%), health centre (29%) and district levels (19%). The intervention arm used more resources at health centre (27%) and community levels (44%) than the control arm at 2% and 4% respectively. Health workers and community members perceived the use of the CDI approach as a good initiative and more favorable over the standard practice of delivering MDA. The use of the CDI in delivery of MDA campaigns against schistosomiasis and STH is feasible, increases coverage and is acceptable in intervention communities. This could be a way forward addressing the sustainability concern when donor support wanes.
