Factors influencing drop-out of households from community based health insurance membership in rural districts of Gurage Zone, Southern Ethiopia: Community based case-control study.

Background: Financial risk-sharing through community-based health insurance is a critical component of universal health coverage. However, its development is a great challenge, not only due to low enrollment but also due to the high dropout rate of members from the program, which threatens its sustainability. So far, the few existing studies in this area have focused on household enrollment into community-based health insurance, rather than on the number of members dropping out. This study aims to identify factors influencing households to drop out of community-based health insurance membership in rural districts of the Gurage Zone, Southern Ethiopia. Methods: A community-based case-control study was carried out from May to July 2021. Supplemented by qualitative focus group discussions. Multi-stage sampling was employed. An interviewer-administered prearranged tool was used for collecting data. Epi-data version 3.1 and SPSS version 21 were used for data entry and analysis. The association between factor and outcome variable was determined using binary logistic regression analysis at Results: From 525 (175 cases and 350 controls) rural household heads 171 cases and 342 controls responded, yielding a response rate of 97.7%. Of those, 73.1 and 69.0% were males in cases and controls, respectively. The statistically significant influencing factors associated with dropout from community-based health insurance were: highest wealth status (adjusted odds ratio [AOR] = 2.36, 95% confidence interval [CI]:1.14-4.87), unfavorable attitude toward CBHI (AOR: 1.81, 95% CI: 1.87-3.37), no illness experienced in the last 3 months (AOR: 5.21, 95% CI: 2.90-9.33). no frequent health facility visits (AOR:5.03, 95% CI:1.17-23.43), no exposure to indigenous community insurance (AOR:0.10, 95% CI: 0.03-0.37), not graduated in the model household (AOR: 3.20, 95% CI:1.75-5.83), being a member in the program for more than 3 years (AOR:0.55, 95% CI: 0.29-0.94), not trusting governing bodies (AOR:10.52, 95% CI:4.70-23.53), the ordered drug was not available in the contractual facility (AOR:14.62, 95% CI:5.37-39.83), waiting time was >3 h (AOR:4.26, 95% CI:1.70-10.66), and poor perception of service quality (AOR:12.38, 95%CI:2.46-62.24). Conclusion: The findings of this study illustrated various factors which positively and negatively influenced households to drop out from CBHI: wealth status, attitude toward CBHI, perceived poor provider attitude toward CBHI members, illness experience in the household, the experience of frequent health facility visits, model household graduation status, trust on CBHI committee (governing bodies), availability of a prescribed drug in the contractual health facility, waiting time and perceived quality of health service from the contractual facility, exposure to any of the indigenous insurance (IDIR and/or IQUB) and length of membership in program. We strongly recommend all responsible stakeholders give strong attention to promoting the community, and for providers to project a favorable attitude toward community-based health insurance, to achieve model household graduation, and improve quality of service by addressing the basic quality-related areas like waiting time, and drug availability).
