Three-Year Impact Assessment of Community Health Worker Programmes on Tuberculosis Prevention and Treatment in Urban Lagos, Nigeria,

Community health worker (CHW) programmes have been implemented to enhance tuberculosis (TB) prevention and treatment in urban areas of Nigeria. A mixed-methods approach was employed, including surveys, focus group discussions, and routine health data collection from public clinics. Significant reductions in TB-related outcomes were observed with CHW interventions. For instance, there was an 18% reduction in mortality rates (95% CI: -20% to -16%). CHW programmes effectively contributed to lower TB prevalence and mortality among urban populations. Further expansion of CHW initiatives is recommended with ongoing monitoring and evaluation. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
