Willingness to pay for community-based health insurance and associated factors in Ethiopia: A systematic review and meta-analysis

Abstract

In Ethiopia, there is low enrollment and a wide discrepancy in willingness to pay for community-based health insurance schemes, and there is a lack of nationally representative data on willingness to pay for community-based health insurance. Thus, this systematic review and meta-analysis aimed to estimate the pooled prevalence of willingness to pay for community-based health insurance and associated factors in Ethiopia. This was developed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Databases such as PubMed/Medline, CINAHL, African Journals Online, and Google Scholar searches were performed to retrieve available published and unpublished studies from December 15 to May 17, 2022. Two independent reviewers screened the retrieved articles. Critical quality appraisal was performed using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. To investigate the sources of heterogeneity, subgroup analysis and meta-regression were performed based on region, study setting (rural/urban), and sample size. RevMan software and STATA 14 software were used for the statistical analysis. A random-effect model was used to estimate the effect size at a 95% confidence interval. A total of 190 studies were retrieved, and six studies were included in the final meta-analysis. The pooled prevalence of willingness to pay for community-based health insurance was 78 (95% confidence interval: 74, 81). A subgroup analysis by region indicated the lowest proportion of willingness to pay community-based health insurance in the Oromia region, 76% (95% confidence interval: 68, 84), and the highest in the Amhara region, 79% (95% confidence interval: 77, 81). Nearly three in four households were willing to pay for community-based health insurance in Ethiopia. Thus, awareness of willingness to pay community-based health insurance is mandatory to improve the implementation of community-based health insurance.
