From: A systematic review of factors that shape implementation of mass drug administration for lymphatic filariasis in sub-Saharan Africa

Author/Country/MDA for LF period Study type Sample characteristics/ Context (setting and areas where MDA for LF was implemented) Study objectives Study findings Outcomes
1. Kisoka et al., 2016 [44]/Tanzania/May and August 2011 Qualitative study Interviews with 21 CDDs, 11 community leaders, 6 religious leaders and 18 FGDs with community members representing adults and adolescents.
(Urban and Rural settings)
Morogoro and Lindi regions.
To gain insight into targeted community members’ perceptions and experiences of LF, the drugs distributed and the phenomenon of MDA, so as to indicate ways of improving the intervention and the interaction between populations and the intervention for future campaigns. Investment in appropriate dissemination of accurate and timely MDA for LF information is essential for guaranteeing community support for the programme. Successful MDA for LF implementation and community participation
2. Bogus et al., 2015 [33]/Liberia/June 2013 Cross sectional study Interviewed 140 community leaders from 32 villages. (Rural setting)
Lofa County, Kolahun District.
To assess community leaders’
knowledge and attitudes regarding resumption of MDA for NTDs after the Ebola virus disease epidemic (EVD).
Shift in national health systems priorities regarding funding, research and development due to EVD.
Temporally halt to all MDA for LF activities in EVD affected areas.
Fears in the community that EVD and MDA might be linked, hence affecting compliance/coverage
Programme sustainability, community participation and coverage
3. Kisoka et al., 2014 [21]/Tanzania/May and August 2011 Cross sectional household survey Data was collected from 3279 adults above 15 years of age.
(Urban and Rural settings) Lindi and Morogoro regions.
To assess, through household questionnaires, the associations between selected predictors and individual drug uptake shortly after the implementation of MDA in two rural and two urban Districts in Tanzania Drug uptake relied more on easily modifiable provider-related factors than on individual perceptions and practices in the target population.
Motivation of drug distributors to visit all households (repeatedly when residents are absent) are likely to have considerable potential for increasing drug uptake.

Qualitative sample size not clearly stated.
(Rural setting)
Builsa, Kassena and Nankana Districts.
To Compare the effectiveness of a delivery strategy based on mass-treatment by the regular health-care system with that of a system of community directed treatment only involving the health services at the level of implementation Health staff and the target communities appreciated the community directed treatment + health services (ComDT/HS) approach more than the health services (HST) stand-alone approach, and were more willing to participate in the community-directed scheme.
Method used to distribute the drugs had a marked effect on coverage.
The treatment coverage achieved by ComDT/HS (74.5%) was much higher than that of HST (43.5%)
The ComDT/HS approach was recommended, especially for areas where access to health facilities is poor and the health workers are over-stretched
Community participation, programmes sustainability and coverage.
