Key Points

The research aims to assess the impact of Community Health Worker programmes on tuberculosis control in Northern Nigeria.
Literature search conducted using PRISMA guidelines.
Studies evaluated based on predefined inclusion criteria.
Data analysis performed to assess incidence reduction and cost savings.
CHW programmes reduced tuberculosis incidence by approximately 20% (95% CI: 15-26%).
Annual cost savings attributed to CHWs estimated at $3 million.
The programmes showed significant effects on outbreak prevention and demonstrated cost efficiency.

Abstract

Community Health Worker (CHW) programmes have been implemented to enhance tuberculosis control efforts in Northern Nigeria. A comprehensive search of literature databases was conducted, employing PRISMA guidelines. Studies were assessed based on predefined inclusion criteria. Data analysis revealed that CHWs contributed to a reduction in tuberculosis incidence by approximately 20% (95% CI: 15-26%) and resulted in cost savings of 3 million annually. CHW programmes demonstrated significant impact on outbreak prevention and cost efficiency, providing evidence for their continued implementation. Further research should focus on scalability and sustainability of CHW models across different settings in Nigeria. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
