Modeling Postoperative Mortality in Older Patients by Boosting Discrete-Time Competing Risks Models
利用提升式离散时间竞争风险模型分析老年患者术后死亡
Elderly patients are at a high risk of suffering from postoperative death. Personalized strategies to improve their recovery after intervention are therefore urgently needed. A popular way to analyze postoperative mortality is to develop a prognostic model that incorporates risk factors measured at hospital admission, for example, comorbidities. When building such models, numerous issues must be addressed, including censoring and the presence of competing events (such as…
