Effect of Community-Based Health Insurance on Healthcare Utilization among Rural Households in Nigeria

Abstract

Community-based health insurance (CBHI) is an important health-financing mechanism designed to improve access to healthcare and provide financial protection, particularly for populations that may have limited access to formal health insurance arrangements. Rural households in Nigeria often experience barriers to healthcare utilization, including low and irregular household income, transportation costs, geographical distance from healthcare facilities, healthcare charges, limited awareness of available services, and inadequate availability of health facilities and essential medicines. Community-based health insurance provides an opportunity for households to pool financial resources and access specified healthcare services through prepayment and risk-sharing arrangements. Healthcare utilization refers to the actual use of healthcare services by household members, including preventive, promotive, curative, maternal and child health, diagnostic, and referral services. Participation in CBHI may reduce financial barriers to healthcare and encourage households to seek care when needed rather than delaying treatment or relying on self-medication. Against this background, this study investigates the effect of community-based health insurance on healthcare utilization among rural households in Nigeria. The study is anchored on the Health Belief Model, Andersen's Behavioral Model of Health Services Use, and the Theory of Planned Behavior. The Health Belief Model provides a framework for understanding households' decisions to seek and utilize healthcare based on perceived susceptibility to illness, perceived severity of health conditions, perceived benefits of healthcare utilization, perceived barriers, and cues to action. Andersen's Behavioral Model explains healthcare utilization in relation to predisposing characteristics, enabling resources, and healthcare needs, with health insurance serving as an important enabling resource that may facilitate access to healthcare services. The Theory of Planned Behavior provides additional insight into how attitudes, social influences, and perceived behavioural control may affect households' decisions to utilize healthcare services. Collectively, these theoretical perspectives provide a suitable framework for explaining the relationship between community-based health insurance and healthcare utilization among rural households in Nigeria. The study will adopt a quantitative comparative cross-sectional research design. Primary data will be collected from rural households in selected Nigerian communities using a structured interviewer-administered questionnaire and healthcare utilization assessment tool. A multistage sampling technique will be employed to select states, local government areas, rural communities, households, and eligible adult household representatives. Households will be categorized according to their participation in community-based health insurance schemes. Community-based health insurance participation will be assessed using indicators such as enrollment status, duration of enrollment, active membership, contribution status, and access to covered healthcare services. Healthcare utilization will be assessed using indicators such as use of primary healthcare facilities, outpatient visits, preventive healthcare services, maternal and child healthcare, immunization, diagnostic services, treatment of common illnesses, hospitalization, and referral services. Additional indicators may include frequency of healthcare utilization, timeliness of healthcare-seeking, usual source of care, and the extent to which healthcare costs influence healthcare-seeking decisions. Where feasible, self-reported utilization will be complemented by appropriate healthcare facility records or insurance documentation, subject to ethical and confidentiality requirements. Descriptive statistics will be used to summarize household sociodemographic and economic characteristics, CBHI enrollment patterns, healthcare access, and utilization patterns. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis, will be used to determine the effect of community-based health insurance on healthcare utilization. Where appropriate, multivariable analysis will be used to account for relevant household characteristics that may influence healthcare utilization. Diagnostic tests will also be conducted to assess the reliability of the research instruments, model assumptions, goodness of fit, multicollinearity, and robustness of the findings. The study is expected to find that community-based health insurance has a significant positive effect on healthcare utilization among rural households in Nigeria. Households enrolled in CBHI schemes are expected to demonstrate greater utilization of primary healthcare, preventive services, maternal and child healthcare, diagnostic services, and treatment services compared with households without community-based health insurance coverage. Insurance participation is expected to reduce the immediate financial burden associated with healthcare and encourage households to seek professional care earlier when illness occurs. CBHI may also improve the use of preventive services by reducing concerns about direct healthcare payments and increasing households' familiarity with participating healthcare facilities. However, insurance coverage alone may not guarantee increased or sustained healthcare utilization because rural households may continue to face barriers such as long distances to facilities, transportation difficulties, shortages of medicines, inadequate health personnel, poor infrastructure, limited service availability, and concerns about the quality of care. Consequently, the effectiveness of community-based health insurance may depend substantially on the availability, accessibility, affordability, and quality of participating healthcare services. The study is expected to contribute to the literature on community-based health insurance, healthcare utilization, rural healthcare, health financing, financial protection, health insurance, primary healthcare, and public health in Nigeria by providing empirical evidence on the effect of CBHI participation on healthcare utilization among rural households. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Health Insurance Authority, state health insurance agencies, National Primary Health Care Development Agency, state primary healthcare development agencies, local government health authorities, community-based health insurance organizations, healthcare providers, development partners, public health practitioners, and policymakers regarding strategies for expanding health insurance coverage and improving rural healthcare access. The study will also provide evidence-based recommendations for strengthening community-based health insurance schemes, improving enrollment and retention, ensuring timely access to covered services, strengthening provider networks, improving the availability of essential medicines and health personnel, enhancing public awareness of CBHI benefits, and promoting equitable healthcare utilization among rural households in Nigeria.
