目的:探讨全面触发工具（GTT）用于检测ICU患者不良事件的应用效果。方法:根据GTT白皮书中触发器的内容，结合国内不良事件上报范畴及部分ICU专科指标，建立16项触发器，采用便利抽样法，选取山东省聊城市第二人民医院病案室2018年7月—2019年6月入住ICU的1 683例患者的病历，根据纳入/排除标准，按照抽样间隔数随机抽取421份出院患者病历，剔除重复病历得到审查病历420份，采用GTT法进行回顾性分析。结果:实际用于审查的病历420份，16项触发器中，14项显示阳性，触发器阳性频次为128例次，涉及患者62例；确定不良事件51例次，涉及患者43例，检出率为10.24%（43/420）；51例次不良事件中，E级37例次（72.55%），F级13例次（25.49%），H级1例次（1.96%），未发现G级和I级。同年度ICU自愿上报不良事件18例，上报率为1.07%（18/1 683）。结论:GTT可有效应用于ICU患者不良事件的检出，设计合理的触发器能提高检出率。“,”Objective:To explore the application effect of global trigger tool (GTT) in detecting adverse events in ICU patients.Methods:According to contents of triggers in the GTT white paper, combined with the scope of domestic adverse event reporting and some ICU indexes, 16 triggers were established. A total of 1 683 medical records were collected from ICU of the Second People's Hospital of Liaocheng in Shandong Province from July 2018 to June 2019. According to the inclusion/exclusion criteria, 421 medical records of discharged patients were randomly selected according to the number of sampling intervals and 420 medical records were reviewed after eliminating repeated medical records. GTT method was used for retrospective analysis.Results:Of the 420 medical records actually used for review, 14 of the 16 triggers were positive, and the positive frequency of triggers was 128 cases, involving 62 patients. Adverse events were identified 51 times, involving 43 patients, with a detection rate of 10.24% (43/420) . Among the 51 cases of adverse events, 37 cases (72.55%) were Grade E, 13 cases (25.49%) were Grade F, and 1 case (1.96%) was Grade H. No Grade G or I was found. In the same year, 18 cases of adverse events were reported voluntarily in ICU, the reporting rate was 1.07% (18/1 683) .Conclusions:GTT can be effectively applied to the detection of adverse events in ICU patients, and a properly designed trigger can improve the detection rate.
