Risk-adjusted monitoring of time to event
事件发生时间的风险调整监测
Recently there has been interest in risk-adjusted cumulative sum charts, CUSUMs, to monitor the performance of e.g. hospitals, taking into account the heterogeneity of patients. Even though many outcomes involve time, only conventional regression models are commonly used. In this article we investigate how time to event models may be used for monitoring purposes. We consider monitoring using CUSUMs based on the partial likelihood ratio between an out-of-control state and an…
