产科静脉血栓风险评估表的信效度研究

目的针对产科特殊性风险,对现临床广泛使用的Autar血栓风险评估表进行修订,形成更适用于产科静脉血栓风险评估的量表,为孕产妇静脉血栓栓塞的预防及治疗提供更科学的依据。方法咨询专家,查阅文献,分析产科住院患者静脉血栓风险的相关危险因素,修订量表,删除Autar血栓风险评估表中不适用于产科的条目,增加产科相关并发症等条目,并进行预试验,结合预试验结果和专家意见反复修订量表,形成产科静脉血栓风险评估量表。对255例住院孕产妇(排除部分特殊情况)进行测评,分析其信效度及临床诊断评价。结果总量表Cronbach’sα系数为0.712,各维度Cronbach’sα系数为0.651~0.724;各模块相关系数介于0.472~0.884,差异具有统计学意义;灵敏度为66.667%,特异度为100%。结论修订后的产科静脉血栓风险评估表各模块均具有一定的鉴别度,并且与静脉血栓风险有一定的相关性,评价效果较Autar血栓风险评估表好。可用于所有孕产妇的静脉血栓风险评估,为孕产妇静脉血栓的预防、监控提供了有力的依据。

Study for the reliability and validity of obstetric vein thrombosis risk assessment table

Objective To address the risk of obstetric specificity,a revised version of the current Autar risk assessment sheet,widely used,is revised,and to develop a more suitable scale for assessing obstetric vein thrombosis risk and provide more scientific basis for the prevention and treatment of maternal venous thrombosis.Methods Obstetric risk assessment scale for venous thromboembolism risk assessment table was revised and formulated by ecpert cunsultation,literature review,related risk factors of hospitalized patients with venous thrombosis analysis,remove the Autar thrombosis risk assessment results and items not suitable for obstetric.Pretesting,increase obstetric complications items and combined with the results of preliminary tests and expert opinion was repeatedly applied to revised scale.255 hospitalized pregnant women(exchuding some special cases)was surveyed to evaluate the reliability,validity and value for chinical diagnosis.Results Total Cronbach was 0.712,the coefficient of each dimension Cronbach's was 0.651~0.724,and the correlation coefficient between each module was 0.884~0.472.There was significant difference.The sensitivity was 66.667%,specificity was 100%.Conclusion Each module of the revised obstetric venous thrombosis risk assessment has a certain degree of differentiation,and has a certain correlation with the risk of venous thrombosis.Its evaluated effect is better than that of Autar's.It can be used in all pregnant women to assess the risk of venous thrombosis,which provides a stong basis for the prevention and control of venous thrombosis in pregnant women.
