BackgroundCommunity-based Health Insurance (CBHI) schemes have been implemented world over as initial steps for national health insurance schemes. The CBHI concept developed out of a need for financial protection against catastrophic health expenditures to the poor after failure of other health financing mechanisms. CBHI schemes reduce out-of-pocket payments, and improve access to healthcare services in addition to raising additional revenue for the health sector. Kisiizi Hospital CBHI scheme which was incepted in 1996, has 41,500 registered members, organised in 210 community associations known as ‘Bataka’ or ‘Engozi’ societies. Members pay annual premiums and a co-payment fee before service utilisation. This study aimed at exploring the feasibility and desirability of scaling up CBHI in Rubabo County, with specific objectives of: exploring community perceptions and determining acceptability of CBHI, identifying barriers, enablers to scaling up CBHI and documenting lessons regarding CBHI expansion in a rural community.MethodsExplorative study using qualitative methods of Key informant interviews and Focus Group Discussions (FGDs). Seventeen key informant interviews, three focus group discussions for scheme members and three for non-scheme members were conducted using a topic guide. Data was analysed using thematic approach.ResultsScaling up Kisiizi Hospital CBHI is desirable because: it conforms to the government social protection agenda, society values, offers a comprehensive benefits package, and is a better healthcare financing alternative for many households. Scaling up Kisiizi Hospital CBHI is largely feasible because of a strong network of community associations, trusted quality healthcare services at Kisiizi Hospital, affordable insurance fees, trusted leadership and management systems. Scheme expansion faces some obstacles that include: long distances and high transport costs to Kisiizi Hospital, low levels of knowledge about health insurance, overlapping financial priorities at household level and inability of some households to pay premiums.ConclusionsCBHI implementation requires the following considerations: conformity with society values and government priorities, a comprehensive benefits package, trusted quality of healthcare services, affordable fees, trusted leadership and management systems.
