Urban slums in Accra, Ghana, are at increased risk of tuberculosis (TB) due to overcrowding and poor living conditions. Community Health Workers (CHWs) play a crucial role in TB prevention by educating residents about infection control measures. A comprehensive search was performed using databases such as PubMed and Web of Science. Studies were included if they reported the efficacy of training programmes delivered to CHWs between and, focusing on changes in knowledge, attitudes, and practices related to TB prevention. Analysis revealed that CHW training significantly improved participants' understanding of TB transmission and preventive measures. Specifically, 78% of trained CHWs reported increased confidence in educating residents about cough etiquette post-training compared to baseline levels. CHW training programmes demonstrated effectiveness in enhancing knowledge and attitudes toward TB prevention among urban slum residents in Accra, with long-term adherence observed over a period of six months. Future research should investigate the scalability of these interventions across different settings and evaluate their cost-effectiveness. Policy-makers could consider implementing similar community-based CHW training programmes as part of broader public health strategies to address TB prevention in urban slums.
