Community health worker (CHW) programmes are crucial in tuberculosis (TB) control efforts, especially in resource-limited settings such as Kibera Refugee Camps in Kenya. A mixed-method approach was employed, including quantitative data analysis and qualitative interviews with CHWs and camp residents. Contact tracing efficiency varied widely among CHWs (mean = 75%, SD = 15%), with dropout rates ranging from 20% to 40%. CHW programmes showed mixed effectiveness in contact tracing, necessitating targeted interventions to improve performance. Enhanced training and support for CHWs are recommended to increase efficiency and reduce dropout rates.
