摘要:

目的 构建先天性心脏病术后患儿中心静脉导管相关深静脉血栓(central venous catheter-associated deep venous thromboses,CADVT)风险预测模型,并验证该模型的预测效果。 方法 便利选取2021年1月—11月在浙江省某三级甲等儿童专科医院心脏外科监护室住院的234例患儿作为建模组,根据是否发生CADVT,将其分为CADVT组(53例)和非CADVT组(181例)。采用Logistic回归分析建立风险预测模型,采用Hosmer-Lemeshow检验判断模型的拟合优度,采用受试者操作特征曲线(receiver operator characteristic curve,ROC)检测模型的预测效果,并绘制列线图。选取2021年12月—2022年2月同一所医院收治的60例先天性心脏病术后患儿作为验证组,采用Hosmer-Lemeshow检验和ROC曲线对模型进行外部验证。 结果 先天性心脏病术后患儿CADVT发生率为22.65%。CVC留置时长(OR=1.172)、D-二聚体浓度(OR=1.169)、纤维蛋白原浓度(OR=3.888)、镇静天数(OR=1.538)、使用血管收缩药(OR=3.554)和儿科危重病例评分(OR=3.308)是其风险因素(P<0.05)。Hosmer-Lemeshow检验结果显示, χ2=4.456,P=0.814,ROC曲线下面积为0.957(95%CI:0.930~0.984),最佳临界值为0.813,灵敏度为0.962,特异度为0.851。外部验证结果显示,该模型的灵敏度为0.857,特异度为0.870,正确率为86.67%。 结论 该风险预测模型的预测效果良好,可为临床评估先天性心脏病术后患儿CADVT发生风险提供参考。

Abstract:

Objective To construct a risk prediction model for central venous catheter-associated deep venous thrombosis(CADVT) in children with congenital heart disease after surgery,and to verify the prediction effect of the model. Methods A total of 234 children hospitalized in the cardiac care unit of a tertiary first-class pediatric hospital in Zhejiang Province from January to November 2021 were conveniently selected as the model building subjects. According to whether CADVT occurred,they were divided into a CADVT group(53 cases) and a non-CADVT group(181 cases). Logistic regression analysis was used to establish the risk prediction model. Hosmer-Lemeshow test was used to determine the goodness of fit of the model. The receiver operator characteristic curve (ROC) was used to test the prediction effect of the model,and a nomogram model was drawn. 60 children with congenital heart disease after surgery in the same hospital from December 2021 to February 2022 were selected as the validation group,and Hosmer-Lemeshow test and ROC curve were used for external verification of the model. Results The incidence of CADVT in children with congenital heart disease after surgery was 22.65%. Intubation duration(OR=1.172),D-dimer concentration(OR=1.169),fibrinogen concentration(OR=3.888),days of sedation(OR=1.538),using of vasoconstrictor(OR=3.554) and pediatric critical illness score(OR=3.308) were its risk factors(P<0.05). The Hosmer-Lemeshow test showed that χ2=4.456,P=0.814,the area under the ROC curve was 0.957(95%CI:0.930~0.984),the optimal critical value was 0.813,the sensitivity was 0.962,and the specificity was 0.851. In the external validation,the sensitivity,specificity and accuracy of the model were 0.857,0.870,86.67%,respectively. Conclusion The risk prediction model constructed in this study has good effects,which can provide a reference for clinical evaluation of the risk of CADVT in children with congenital heart disease after surgery.
