摘　　要：近年来,统计过程控制(SPC)己被广泛用于监测临床从业人员的表现.本文建立了两个阶段II的风险调整的几何控制图,即累积和(CUSUM)和加权似然比检验(WLRT)控制图,用来监控手术的表现.通过模拟实验,以平均运行长度(ARL)为标准,对所提出的控制图的性能进行了评估和比较.结果表明,所提出的控制图可以有效地检测到过程参数的变化.In recent years, statistical process control （SPC） has been widely used to monitor the performance of clinical practitioners, such as surgeons and general practitioners. In this paper, two risk-adjusted geometric control charts namely cumulative sum （CUSUM） and weighted likelihood ratio test （WLRT） are proposed to monitor surgery performance in phase Ⅱ. The performance of the proposed control charts is evaluated and compared by simulation experiments for different shift values in the parameters of a risk-adjusted logistic regression model in terms of the average run length （ARL） criterion. The results show that all methods work well in the sense that they can effectively detect shifts in the process parameters.
