基于Delphi-AHP法构建腹腔镜左肝外叶切除术技能评价工具

Construction of an assessment tool for laparoscopic left lateral sectionectomy skills based on the Delphi-AHP method

目的构建腹腔镜左肝外叶切除手术技能评价工具。方法于2023年11月至2024年1月邀请来自全国不同地区的22位肝胆胰外科临床专家为函询对象,通过文献回顾确定初步指标体系,通过德尔菲法和层次分析法确定各级指标以及权重。结果两轮咨询专家积极系数分别为100.00%、90.91%,权威系数分别为0.984、0.985,肯德尔协调系数分别为0.231、0.193(P<0.001),两轮专家咨询问卷的Cronbach’s α系数分别为0.905和0.865。最终形成包括5个一级指标和23个二级指标的腹腔镜左肝外叶切除手术技能评价工具。层次分析结果显示,二级指标各矩阵的一致性比例(CR)<0.1,符合一致性检验要求。结论本研究构建的腹腔镜左肝外叶切除手术技能评价工具客观可信,可为客观评价新手术者的手术能力提供参考依据。

Objective To construct an assessment tool for laparoscopic left lateral sectionectomy skills.Methods From November 2023 to January 2024,22 clinical experts in hepatopancreatobiliary surgery from different regions of China were selected for this study.A preliminary indicator system was established through literature review,and the indicators and their weights at each level were determined using the Delphi method and analytic hierarchy process(AHP).Results In the two rounds of consultation,the expert positive coefficients were 100.00%and 90.91%,authority coefficients were 0.984 and 0.985,Kendall coefficients were 0.231 and 0.193(P<0.001),and Cronbach's α coefficients were 0.905 and 0.865,respectively.A skill assessment tool for laparoscopic left lateral sectionectomy skills was constructed consisting of 5 primary indicators and 23 secondary indicators.AHP analysis showed that the concordance rate of each matrix of the secondary indicators was<0.1,meeting the consistency test requirements.Conclusions The assessment tool for laparoscopic left lateral sectionectomy skills developed in this study is objective and reliable for evaluating the surgical skills of novice surgeons.
