Community-Based Health Insurance (CBHI) in Rwanda was promulgated as the best alternative to address the financial barriers for accessibility to health care services for the poor population and the informal sector. The purpose of this study was to investigate whether CBHI reduce Out-of-pocket health expenses for their members as compared to non-members and to what extent CBHI provide financial protection for the poorest population. This research based itself on secondary source of data primarily collected for a prospective quasi-experimental design which evaluated the impact of Performance-Based Financing. The primary study had reported on the Out-Of-Pocket expenses for health by members and non-members of CBHI; residing in a sample of 1961 households; in addition to their demographics and socio-economic characteristics. The findings indicate that insured individuals were about 2.6 times more likely to utilize health care services than respondents without health insurance. It is also worth noting that households with health insurance coverage were less likely to experience a catastrophic health expenditure than households without health insurance (aOR: 0.744; 95% CI:[0.586 - 0.945]), and that the effect of health insurance coverage was higher in people living in poor households than in people living in middle or richer households.
