Trends and correlates of patient satisfaction with services under the National Health Insurance Scheme of Nigeria: A review

Background: In spite of over a decade of operations, the National Health Insurance Scheme (NHIS) of Nigeria has continuously been criticized for its quality of services. Healthcare consumer satisfaction surveys (an important measure of service quality worldwide) in this domain have presented differing accounts of satisfaction with the services of the NHIS from their vantage perspectives. This narrative review aimed at studying the preliminary trends in the utilization of and patient satisfaction with the NHIS services. The correlates of patient satisfaction were also studied. Materials and Methods: We searched local literature whose full texts were accessible using predominantly Google Scholar. Results: We found progressive improvement in scheme enrolment, service utilization, and above-average overall satisfaction scores (i.e., >50% of respondents were satisfied) from most studies. Overall satisfaction scores/ratings were associated patients’ level of education, knowledge of the scheme, years of enrolment, facility cleanliness, consultation time, pharmaceutical services, ease in accessing medical records and laboratory results, health worker availability, health worker friendliness, and responsiveness to patients’ requests. Conclusion: The observed trajectory in service utilization, satisfaction scores, and their correlates may be useful for strategic planning to improve NHIS services in the country toward universal health coverage.
