Assessing the Effectiveness of Community Health Worker Programs on Healthcare Accessibility and Utilization in Luapula Province, Zambia

Abstract

Community Health Workers (CHWs) play a critical role in strengthening primary health care systems and improving healthcare access in underserved communities. However, evidence on the operational effectiveness of CHW programs at sub-national level remains limited. This study assessed the effectiveness of Community Health Worker programs on healthcare accessibility and utilization in Luapula Province, Zambia. A mixed methods research design was used, combining quantitative and qualitative approaches. Primary data were collected from 95 CHWs, 190 community members, and 15 facility-based health workers using structured questionnaires, interviews, and focus group discussions. Quantitative data were analyzed using descriptive statistics and exploratory factor analysis in SPSS to validate constructs related to training, motivation, logistics, and resource mobilization, while qualitative data were analyzed thematically. Findings show that CHW programs significantly contribute to community health project implementation through training exposure, worker motivation, and community-level engagement. Most CHWs reported receiving periodic training and demonstrated professional service delivery practices. However, major gaps were identified in availability of medicines, transport, diagnostic tools, communication equipment, and referral systems. Motivation mechanisms existed but were inconsistent across programs. Resource mobilization systems were present but weakly funded and lacked transparent community participation. The study concludes that while CHW programs positively influence healthcare accessibility and utilization, their effectiveness is constrained by systemic resource and support limitations. Strengthening phased training models, harmonizing incentives, improving logistics support, and enhancing community resource mobilization structures are essential to improve program performance and sustainability.
