Background: In Tanzania, Community Health Fund (CHF) was initiated in 1996 with the aim of implementing a community Based Health Financing Scheme through volunteer membership contribution as additional income to improve access to quality health care service for marginalized rural community. The evaluation was conducted to assess factors that influencing Community Health Fund member‟s satisfaction with treatment services offered through Community Health Fund membership. Methods: A cross sectional study design was employed that involved 153 respondents for which allowed collection of data that provided a descriptive estimates of the population parameters. The study was guided by Donabedian conceptual framework where by questionnaires were designed to assess structures, process of service delivery and treatment outcome as attributes of satisfaction. A sample size of 153 respondents was calculated by statalcl 13 (64-bit) within the effect size of 0.7– 0.8 one sample (Alpha = CI=95%, α=0.05, two-sided). Two health facilities were involved in the exit interview where by respondents were selected and interviewed based on their inclusion criteria. Results: A bigger proportional of female 55(60%) and 40(60%) in Likombe and Mikindani compared to male 37(40%) and 21(34%). A big proportional of respondents revealed that structures of health facility include availability of adequate Health Care Providers (HCPs) and medicines influence their satisfaction (p=0.05). Most of respondents were happy with the quality of available medical supplies and it was statistically significant at satisfaction level (p=0.02). The process of service delivery indicate that CHF members spend more than one hour to receive treatment service in health facility from their first contact and there was significant association between time spent and satisfaction(p=0.02). However, significance association was found between happiness with treatment and overall satisfaction level with services (p=0.03) though members do not feel much difference from being a CHF member and other patients.
