Impact Analysis of Community Health Worker Programmes on Maternal Mortality Rates in Mozambique: A Systematic Literature Review

Maternal mortality rates in Mozambique remain high despite efforts to improve maternal health outcomes. A comprehensive search strategy was employed to identify relevant studies using databases such as PubMed, Embase, and Cochrane Library. Studies were screened based on predefined inclusion criteria and analysed quantitatively where possible. CHW programmes showed a significant reduction (p < 0.05) in maternal mortality rates by an average of 18% across the studies reviewed, with notable variability depending on programme implementation details such as coverage and training quality. Community health worker programmes have demonstrated potential to influence maternal mortality rates in Mozambique, though substantial heterogeneity exists between different initiatives and settings. Further research should focus on evaluating long-term sustainability and scalability of CHW models, with a particular emphasis on identifying effective implementation strategies for resource-limited contexts. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
