Facility- and community-based delivery of micronutrient powders in Uganda: Opening the black box of implementation...

Micronutrient powders (MNP) have the potential to increase micronutrient intake, yet documentation of implementation lessons remains a gap. This paper presents results of a pilot in Uganda comparing community- and facility-based delivery of MNP and documenting experiences of caregivers and distributors. The pilot's mixed method evaluation included a cross-sectional endline survey, monthly household visits, and midline and endline interviews. Primary outcomes were ever-covered (received ≥1 MNP packet), repeat-coverage (received ≥2 MNP packets), and adherence (consumed no more than 1 MNP sachet per day, consumed MNP with food, and consumed MNP 3+ days in past week). An adjusted Wald chi-square test compared differences in programme outcomes between arms, and logit regression identified predictors to adherence. Key informant interviews were coded thematically. Most programme outcomes in the endline survey were statistically significantly higher in the community arm, although in both arms, adherence was lower than other outcomes (adherence 31.4% in facility vs. 58.3% in community arm). Counselling, receipt of communication materials, perceived positive effects, MNP knowledge, and child liking MNP were consistent predictors of adherence in both arms. Qualitative findings corroborated survey results, revealing that social encouragement and advocacy facilitated use and that forgetting to give MNP was a barrier. Facility arm caregivers also cited distance, time, and transportation cost as barriers. Distributors had positive experiences with training and supervision but experienced increased workloads in both arms. MNP programme design is context-specific but could benefit from strengthened community sensitization, continued and more effective counselling for caregivers, and increased support for distributors.
