摘　　要：目的探索移动百分位数控制图法在重症监护病房器械相关感染监测预警中应用的可行性,为医院感染监测预警工作提供参考。方法收集20172022年苏南地区某三级甲等医院重症监护病房器械相关感染月发病率数据,建立基于不同界值的控制图模型,选出最佳预警界值。结果综合比较灵敏度、特异度、阳性预测值、约登指数和受试者工作曲线的计算结果,中央导管相关血流感染、呼吸机相关肺炎和导尿管相关尿路感染的最优预警界值分别为P_(85)、P_(90)和P_(75),对应的约登指数分别为0.91、1.00和0.80。结论控制图法在器械相关感染监测预警中,具有简单实用和预警功效高的特点。Objective To explore the feasibility of the application of mobile percentile control chart method in the monitoring and early warning of device-associated infection in the intensive care unit,so as to provide guidance for the monitoring and early warning for healthcare-as sociated infection.Methods Monthly incidence data of device-associated infection in the intensive care unit of a tertiary hospital in southern Jiangsu Province were collected from 2017 to 2022,and the early warning models were established by using control chart method.The optimal thresholds were selected through establishing a control chart model based on different boundary values.Results By comparing the results of sensitivity,specificity,positive predictive value,Yorden index and the figure of receiver operating characteristic curve,the optimal warning thresholds of central line associated-bloodstream infection,ventilator-associated pneumonia and catheter-associated urinary tract infection were P_(85),P_(90)and P_(75),respectively,and the corresp onding Yordon indices were 0.91,1.00 and 0.80,respectively.Conclusion Control chart method could be app lied in the monitoring and early warning of device-associated infections,conveniently,practically and efficiently.
