【 摘 要 】

Objective: This study aimed to evaluate the cost-effectiveness of a group diabetes education program delivered by health promoters in community health centers in the Western Cape, South Africa. Methods: The effectiveness of the education program was derived from the outcomes of a pragmatic cluster randomized controlled trial (RCT). Incremental operational costs of the intervention, as implemented in the trial, were calculated. All these data were entered into a Markov micro-simulation model to simulate clinical outcomes and health costs that were expressed as an Incremental Cost Effectiveness Ratio (ICER). Results: The only significant effect from the RCT at one year was a reduction in blood pressure (systolic blood pressure -4.65 mmHg (95%CI: -9.18 to -0.12) and diastolic blood pressure -3.30 mmHg (95%CI: -5.35 to -1.26)). The ICER for the intervention, based on the assumption that the costs would recur every year and the effect could be maintained, was 1862 $/QALY gained. Conclusion: A structured group education program performed by mid-level trained healthcare workers at community health centers, for the management of Type II diabetes in the Western Cape, South Africa is therefore cost-effective. Practice implications: This cost-effectiveness analysis supports the more widespread implementation of this intervention in primary care within South Africa. (C) 2015 The Authors.
