汉化RAC风险评估模型在CABG患者中的应用价值

Application value of RAC model in predicting readmission after coronary artery bypass graft

目的:引进并汉化RAC风险评估模型,检验其区分度和校准度,探索其在中国人群中的适用度,以提供中国冠状动脉旁路移植术(CABG)患者术后再入院风险有效评价的工具。方法:对源模型进行翻译汉化,收集2017年在武汉市亚洲心脏病医院接受CABG手术的患者825例,获取病历,根据汉化模型对患者进行评分,根据评分结果用ROC曲线检验其区分度,用H-L检验其校准度。结果:汉化RAC风险预测模型在中国CABG患者中应用价值较高(ROC曲线下面积0.714[95%CI(0.640,0.788)],H-L检验:P=0.823)。结论:汉化RAC风险预测模型可用于临床工作中CABG患者再入院风险的预测。

Objective:We introduce the Sinicized RAC risk prediction model to test its discrimination and calibration,and explore its applicability in Chinese population,then provide an effective tool for evaluating the risk of readmission in Chinese patients with CABG.Method:The source model was translated into Chinese.The 825patients undergoing CABG operation in Wuhan Asian Heart Hospital in 2017were selected to obtain medical records.According to the Sinicized model,the patients were scored.Their discrimination was tested by ROC curve,and their calibration was tested by H-L.Result:The value of Chinese RAC risk prediction model was high in Chinese CABG patients.(The area under ROC curve was 0.714[95%CI(0.640,0.788)],H-L test:P=0.823).Conclusion:The Chinese RAC risk prediction model can be used to predict the risk of readmission of CABG patients.
