Factors influencing implementation of the Community Health Fund in Tanzania.

Although prepayment schemes are being hailed internationally as part of a solution to health care financing problems in low-income countries, literature has raised problems with such schemes. This paper reports the findings of a study that examined the factors influencing low enrollment in Tanzania's health prepayment schemes (Community Health Fund). The paper argues that district managers had a direct influence over the factors explaining low enrollment and identified in other studies (inability to pay membership contributions, low quality of care, lack of trust in scheme managers and failure to see the rationale to insure). District managers' actions appeared, in turn, to be at least partly a response to the manner of this policy's implementation. In order better to achieve the objectives of prepayment schemes, it is important to focus attention on policy implementers, who are capable of re-shaping policy during its implementation, with consequences for policy outcomes.
