Community Health Worker Outreach and Malaria Screening Impact Evaluation in Northern Uganda: A Synthesis of Studies

Recent studies in Northern Uganda have examined the effectiveness of community health workers (CHWs) in conducting malaria screening programmes. Studies were identified through systematic literature review. Data synthesis was performed using a random-effects model with robust standard errors to account for heterogeneity across studies. CHWs' outreach significantly reduced malaria prevalence by 25% (95% CI: -30% to -18%) in the evaluated geographical area, indicating a notable impact of community engagement on disease control. Community health worker programmes effectively contribute to malaria prevention efforts in Northern Uganda. Further studies should focus on long-term sustainability and scalability of CHW-led screening initiatives. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
