摘要
目的构建食管癌术后患者误吸危险因素评估量表,并确立各级指标权重系数。方法对17位专家采用德尔菲法进行2轮咨询,并应用层次分析法建立层次结构模型,构造判断矩阵,计算各指标权重并检验其逻辑一致性。结果2轮函询专家的权威系数分别为0.875、0.867,一级指标协调系数分别为0.497、0.318(均P<0.01)。确立的评价体系包括5个一级指标、30个二级指标,一级指标的权重系数分别为0.1761、0.1212、0.3807、0.2417、0.0803;各级指标层次单排序及总排序一致性比率均<0.1,具有满意的一致性。结论构建的评价指标体系科学可行,各指标权重合理,能为食管癌误吸危险因素评估提供客观、可量化的依据。
Objective To develop an aspiration risk assessment scale for patients following esophagectomy.Methods Seventeen experts were consulted for 2 rounds by Delphi method,then the analytic hierarchy process was employed to establish the hierarchical structure model,the judgement matrix was constructed,the weight of each indicator were calculated,and the logical consistency was tested.Results The authority coefficient of experts in the 2 rounds was 0.875 and 0.867 respectively,the coordination coefficient for the first-level indicators was 0.32 and 0.37(P<0.01).The established evaluation index system included 5 first-level indicators,30 second-level indicators.The weight coefficient of structure quality,process quality and result quality for the first-level indicators was 0.1761,0.1212,0.3807,0.2417 and 0.0803.The consistency ratio of single ordering weight value and total sequencing weight value at different levels were less than 0.10,which indicated satisfactory consistency.Conclusion The evaluation index systemis rational and feasible,and the weight of each indicator is reasonable,and it may provide objective and quantitative evidence for aspiration risk assessment scale for patients following esophagectomy.
