临时透析导管失效模式与效应分析风险评估量表的编制及信效度检验

Development and testing of validity and reliabilityof a risk assessment scale for failure mode and effects analysis of temporary dialysis catheters

目的:编制一种科学、有效的临时透析导管失效模式与效应分析风险评估量表。方法:以失效模式与效应分析为理论框架,在文献回顾、小组讨论、德尔菲法的基础上研制量表初稿,再选取201名肾病科或血液净化中心医护人员进行问卷调查,测量量表的信效度,形成最终量表。结果:量表包括5个流程步骤(一级条目),24个潜在失效模式(二级条目),26个失效后果(三级条目)。探索性因子分析共提取5个公因子,累计方差贡献率86.282%。总量表的Cronbach′s α系数为0.983,折半信度为0.929,重测信度为0.803。总量表的内容效度指数(S-CVI)为0.925,条目水平的内容效度指数(I-CVI)为0.832~1.000。结论:该量表的编制过程科学严谨、信效度良好,能有效评估血液透析病人临时透析导管的高风险流程,为制定风险干预措施提供依据。

Objective:To develop a scientific and effective risk assessment scale for failure modes and effects analysis of temporary dialysis catheters.Methods:Taking failure mode and effect analysis as the theoretical framework,the first draft of the scale was developed based ona literature review,group discussion,and the Delphi method.A total of 201 medical staff from the nephrology department or blood purification center were selected to conduct a questionnaire survey to measure the reliability and validity of the scale,then form the final scale.Results:The scale included 5 process steps(first-level items),24 potential failure modes(second-level items),and 26 failure consequences(third-level items).A total of 5 common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 86.282%.The Cronbach′sαcoefficient of the total scale was 0.983,the half-way reliability was 0.929,and the test-retest reliability was 0.803.The total scale′scontent validity index(S-CVI)was 0.925,and the item level′scontent validity index(I-CVI)was 0.832-1.000.Conclusions:The scale is scientifically rigorous and has good reliability and validity.It may effectively evaluate the high-risk process of temporary dialysis catheters in hemodialysis patients and provide a basis for formulating risk intervention measures.
