目的 应用CART决策树和logistic回归构建住院肝硬化患者发生衰弱风险预测模型,比较2种模型预测效果.方法 采用便利抽样法,选取2023年3-10月某三级甲等医院确诊并收治的317例肝硬化患者,运用CART决策树和logistic回归构建住院肝硬化患者发生衰弱风险预测模型,内部验证采用Bootstrap重采样1 000次的方法,采用准确度、灵敏度、特异度、阳性预测值、阴性预测值和受试者工作特征(ROC)曲线下面积(AUC)对2种模型的性能进行比较.结果 CART决策树与logistic回归准确度为86.3%和89.1%、灵敏度为76.5%和92.5%、特异度为91.8%和82.8%、阳性预测值为84.8%和91.6%、阴性预测值为86.8%和83.8%、AUC为0.876和0.965.结论 logistic模型对住院肝硬化患者发生衰弱风险的预测性能优于CART决策树模型,可为衰弱的早期筛查和预防提供参考.
Objective To construct fateful risk prediction models for inpatients with cirrhosis by CART decision tree and logistic regression respectively,and compare the prediction effects of 2 models.Methods A total of 317 pa-tients with cirrhosis who met the admission criteria in a tertiary A hospital from March to October 2023 were select-ed by convenience sampling method,and CART decision tree and logistic regression were used to construct a frailty risk prediction model for inpatients with cirrhosis.In internal verification,the method of Bootstrap resampling 1 000 times was used to compare the performance of 2 models by using accuracy,sensitivity,specificity,positive predic-tive value,negative predictive value,and area under the curve(AUC)of receiver operating characteristic(ROC).Result The accuracy of CART decision tree and logistic regression were 86.3%and 89.1%,the sensitivity was 76.5%and 92.5%,the specificity was 91.8%and 82.8%,the positive predictive value was 84.8%and 91.6%,the negative predictive value was 86.8%and 83.8%,and the AUC was 0.876 and 0.965.Conclusion logistic model is better than CART decision tree model in predicting frailty risk in inpatients with cirrhosis,which can provide ref-erence for early screening and prevention of frailty.
