摘要:

目的 构建慢性病药物可及性评价指标体系，为相关政策决策者与研究者开展慢性病药物可及性评价提供参考。方法 采用德尔菲法对20名专家开展2轮函询，就拟定的慢性病药物可及性评价指标体系进行评分。通过统计专家积极性、专家权威程度、专家意见集中程度与协调程度判断指标体系可靠性，基于界值法筛选指标，并结合专家意见对指标进行调整后确立最终的指标体系。结果 2轮函询的专家积极系数分别为92.31%与83.33%，专家权威系数分别为0.75与0.84，指标重要性得分均值分别为3.35与3.42，协调系数分别为0.183与0.239。调整后形成由4个维度、21项指标组成的慢性病药物可及性评价指标体系。结论 本研究基于德尔菲法设计的指标体系较可靠，可用作慢性病药物可及性的调查评价。

Abstract:

OBJECTIVE To establish an index system of access to drugs for chronic diseases, so as to provide reference for relevant policy makers and researchers to evaluate accessibility of chronic disease drugs.METHODS Delphi method was used to conduct two rounds of enquiries on 20 experts to score the proposed index system. The reliability of the index system was judged by the experts’ positive coefficient, the authority coefficient, the concentration of experts’ opinions and the degree of experts’ coordination. Indicators were first selected by the cut-off method, and the final index system was established after the adjustment of indicators concerning experts’ opinions.RESULTS The positive coefficients of experts were 92.31% and 83.33%, the authority coefficients were 0.75 and 0.84, the mean importance scores of indicators were 3.35 and 3.42, and the coordination coefficients were 0.183 and 0.239, respectively. After the adjustment, an index system for the accessibility of drugs for chronic diseases was formed, consisted of 4 dimensions and 21 items.CONCLUSION The index system established in this study through Delphi method is reliable and can be applied to investigate the accessibility of drugs for chronic diseases.
