摘要
目的:检验围生期静脉血栓栓塞症风险评估表在产妇中的信效度。方法:采用方便抽样法选取2021年3月1日—2021年8月31日在上海交通大学医学院附属国际和平妇幼保健院产科病房住院的230例产妇为研究对象,采用围生期静脉血栓栓塞症风险评估表对产妇进行调查,检验评估表的信效度,并确定诊断阈值和风险分层。结果:围生期静脉血栓栓塞症风险评估表的Cronbach’s α系数为0.732,评定者间的组内相关系数为0.986,条目水平的内容效度指数为0.824,量表水平的内容效度指数为0.930,受试者工作特征曲线下面积为0.809[95%置信区间(0.752,0.858)],分值为6分时约登指数最大。风险分层结果显示,总分6~7分时产妇发生静脉血栓栓塞症的风险为低危,总分8~11分时产妇发生静脉血栓栓塞症的风险为中危,总分≥12分时产妇发生静脉血栓栓塞症的风险为高危。结论:围生期静脉血栓栓塞症风险评估表具有良好信效度,其诊断阈值及风险分层合理,在产后病人静脉血栓栓塞症评估应用中表现出了较高的预测效能。
Objective:To test reliability and validity of Risk Assessment Scale for Perinatal Venous Thromboembolism in parturients.Methods:230 parturients who were hospitalized in obstetric ward of the International Peace Maternity and Child Health Hospital,School of Medicine,Shanghai Jiao Tong University were selected by convenient sampling as subjects from March 1,2021 to August 31,2021.The Risk Assessment Scale for Perinatal Venous Thromboembolism was used to investigate parturients for test reliability and validity of the assessment scale,and determining diagnostic threshold and risk stratification.Results:Cronbach’s α coefficient of the Risk Assessment Scale for Perinatal Venous Thromboembolism was 0.732,the intraclass correlation coefficient among assessors was 0.986,item-level content validity index was 0.824,scale-level content validity index was 0.930,area under receiver operator characteristic curve was0.809[95%CI(0.752,0.858)],and Youden index was the largest when the score was 6.The results of risk stratification showed that risk of venous thromboembolism in parturients was low when total score were 6 or 7,risk of venous thromboembolism in parturients was medium when total score were from 8 to 11,and risk of venous thromboembolism in parturients was high when total score were≥12.Conclusions:The Risk Assessment Scale for Perinatal Venous Thromboembolism has good reliability and validity,and its diagnostic threshold and risk stratification are reasonable,which shows high predictive efficiency in evaluation of venous thromboembolism in parturients.
