A quality assessment index framework for public health services: a Delphi study.

OBJECTIVES: This study sought consensus-based indices for quality assessment of the public health service (QAPHS) to evaluate the service quality of public health in Shenzhen and other cities in China. STUDY DESIGN: A qualitative study. METHODS: A list of quality assessment indices was formed based on Donabedian theory. These indices were presented to an expert panel in a two-round Delphi study to establish a consensus view. A weight of indices was established to validate the applicability and practicability of the framework. The specialist authority coefficient and Kendall's W were also calculated based on statistical analysis. RESULTS: A total of 30 experts participated in the Delphi study. Consensus was reached on four first-grade indices, nine second-grade indices and 28 third-grade indices. The specialist authority coefficient (Cr) was high (between 0.88 and 0.92), while Kendall's coefficient (W) of all the indices was ＞0.5 with statistical significant differences (P ＜ 0.05). This indicated correlation among panelists and had high reliability. CONCLUSIONS: A unified and hierarchical quality assessment index framework for public health services was established. The framework should be further tested and improved in practice.
