Influence of Community Health Insurance Enrollment on Primary Healthcare Utilization among Rural Households in Nigeria

Abstract

Access to affordable and quality healthcare remains an important public health concern in rural communities in Nigeria, where households may experience financial, geographical, and other barriers to healthcare utilization. Community health insurance provides a potential mechanism for reducing direct financial barriers by pooling healthcare risks and providing enrolled households with access to covered health services. Community health insurance enrollment refers to the registration and continued participation of eligible individuals or households in a community-based health insurance arrangement that provides financial coverage for specified healthcare services. Primary healthcare utilization refers to the extent to which individuals and households use primary healthcare facilities and services for preventive, promotive, curative, and basic rehabilitative care. In rural Nigeria, low income, out-of-pocket healthcare payments, distance to healthcare facilities, limited availability of health services, and inadequate awareness of health insurance may discourage households from seeking appropriate primary healthcare. Enrollment in community health insurance may improve financial access to healthcare and encourage households to use primary healthcare services when needed. However, the extent to which insurance enrollment influences actual utilization remains an important empirical question. Against this background, this study investigates the influence of community health insurance enrollment on primary healthcare utilization among rural households in Nigeria. The study is anchored on Andersen's Behavioral Model of Health Services Use, the Theory of Health Insurance Demand, and the Health Belief Model. Andersen's Behavioral Model explains healthcare utilization through predisposing characteristics, enabling resources, and healthcare needs, with health insurance representing an important enabling resource. The Theory of Health Insurance Demand provides a framework for understanding households' decisions to obtain health insurance based on perceived healthcare risks, expected financial protection, and anticipated benefits of insurance coverage. The Health Belief Model explains healthcare utilization through perceptions of disease susceptibility, disease severity, perceived benefits of healthcare use, perceived barriers, and cues to action. Collectively, these theoretical perspectives provide a suitable framework for explaining how community health insurance enrollment may influence primary healthcare utilization among rural households in Nigeria. The study will adopt a quantitative cross-sectional research design. Primary data will be collected from rural households in selected Nigerian communities using a structured interviewer-administered questionnaire and a primary 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. Community health insurance enrollment will be assessed using indicators such as household enrollment status, duration of enrollment, membership status, coverage of household members, frequency of premium payment where applicable, and awareness of covered healthcare services. Primary healthcare utilization will be assessed using indicators such as frequency of visits to primary healthcare centres, use of primary healthcare facilities during illness, preventive healthcare visits, immunization-related services where applicable, antenatal and postnatal services where relevant, treatment of common illnesses, health consultations, and healthcare-seeking from primary healthcare facilities. Additional information will be collected on household income, household size, education, occupation, distance to healthcare facilities, health needs, previous healthcare expenditure, and availability of primary healthcare services. Descriptive statistics will be used to summarize household characteristics, insurance enrollment patterns, healthcare expenditure, and primary healthcare utilization. Inferential statistical techniques, including chi-square tests, correlation analysis, and logistic or multiple regression analysis, will be used to determine the influence of community health insurance enrollment on primary 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 health insurance enrollment has a significant positive influence on primary healthcare utilization among rural households in Nigeria. Enrolled households are expected to demonstrate greater use of primary healthcare facilities and services compared with households without community health insurance coverage. By reducing the immediate financial burden associated with healthcare services, insurance enrollment is expected to encourage households to seek care earlier when illness occurs and increase their use of preventive and routine primary healthcare services. Insurance coverage is also expected to reduce reliance on self-medication and delayed healthcare-seeking caused by concerns about healthcare costs. However, insurance enrollment alone may not guarantee increased utilization where primary healthcare facilities are distant, poorly equipped, inadequately staffed, or unable to provide essential medicines and quality services. Consequently, the benefits of community health insurance may depend partly on the availability, accessibility, and quality of covered primary healthcare services. The study is expected to contribute to the literature on community health insurance, health insurance enrollment, primary healthcare utilization, health financing, financial protection, rural healthcare, healthcare access, and public health in Nigeria by providing empirical evidence on the relationship between insurance coverage and healthcare utilization among rural households. The findings will provide useful information to the National Health Insurance Authority, state health insurance agencies, Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, state ministries of health, local government health authorities, community health insurance organizations, primary healthcare providers, development partners, and policymakers regarding strategies for expanding health insurance coverage and improving healthcare utilization. The study will also provide evidence-based recommendations for increasing community health insurance enrollment, improving awareness of insurance benefits, strengthening premium affordability, expanding coverage among rural households, improving the quality of participating primary healthcare facilities, and strengthening coordination between insurance schemes and primary healthcare providers in Nigeria.
