成人术中低体温风险评估量表的研制及检验

Development and validation of an adult intraoperative hypothermia risk assessment scale

目的 研制成人术中低体温风险评估量表并进行信效度检验,为手术室护理人员提供科学、有效的评估工具。方法 通过文献回顾建立指标条目池,根据2轮专家函询结果形成量表初稿,采用便利抽样法抽取150例择期手术患者进行术中低体温风险评估,采用ROC曲线确定量表危险阈值,四分位法进行量表风险等级划分,采用Cronbach′sα系数进行信度检验。结果 成人术中低体温风险评估量表包含2个维度、10个风险因素;量表危险阈值为15分,ROC曲线下面积为0.820,灵敏度为100%,特异度为47.52%;15~16分为低风险,17~20分为中风险,>20分为高风险;量表Cronbach′sα系数为0.780。结论 成人术中低体温风险评估量表具有良好的预测效能,可用于成人术中低体温风险评估。

Objective To develop an adult intraoperative hypothermia risk assessment scale,and to test its reliability and validity,so as to provide a scientific and effective assessment tool for nurses in operating room.Methods An item pool was constructed through literature review,which was used to form a draft scale after a two-rounds expert consultation,then the draft scale was used to investigate 150 elective surgery patients using convenient sampling to assess the risk of intraoperative hypothermia.The ROC curve was used to finally determine the risk threshold of the scale,the quartile method was used to classify its risk levels,and Cronbach′s alpha coefficient was used to test its reliability.Results The adult intraoperative hypothermia risk assessment scale included 2 dimensions and 10 risk factors.Its risk threshold was 15 points,ROC curve was 0.820,and its sensitivity was 100%,specificity was 47.52%.The risk assessment 15-16 points was defined low risk,17-20 points was medium risk,>20 points was high risk.The Cronbach′s alpha coefficient of the scale was 0.780.Conclusion The adult intraoperative hypothermia risk assessment scale displays good predictive performance,so it can be utilized for assessing adult intraoperative hypothermia risk.
