基于关联规则的重症监护室患者气管插管非计划拔管事件特征性因素分析

Characteristic factors of unplanned endotracheal extubation events in intensive care unit:an analysis based on association rules

目的:挖掘重症患者气管插管非计划拔管事件发生的关联因素,为重症监护室气管插管患者非计划拔管的预防与管理提供科学依据。方法:基于关联规则,对温州医科大学附属第一医院2018年1月1日至2021年8月31日上报的109例气管插管非计划拔管事件资料进行数据分析,探讨重症监护室患者气管插管非计划拔管的关联因素。结果:通过条件设定及χ2检验筛选出309条规则,结合护理专业知识,最终得到16条强关联规则。重症监护室患者气管插管非计划拔管事件中的风险因素包括拔管前约束不到位、气管插管持续留置1~2 d、未镇静、夜班、病区护患比<1/3、男性、年龄≥60岁、吸烟史、谵妄筛查低风险、神志清醒、躁动、文化程度小学、手术史、心动过速、体温高、神经系统疾病。结论:通过数据挖掘,获取了重症患者气管插管非计划拔管事件发生的各因素之间的关联规律,为重症监护室气管插管非计划拔管预防和管理体系的构建提供指导,确保气管插管患者的安全。

Objective:To explore the related factors for unplanned endotracheal extubation events in intensive care unit(ICU),so as to provide scientific basis for the prevention and management of unplanned endotracheal extubations in ICU patients.Methods:Based on the association rules,data of 109 cases of unplanned endotracheal extubations reported from the First Affiliated Hospital of Wenzhou Medical University between January 1st 2018 to August 31st 2021 were analyzed.Results:Through condition setting and Chi-square test,309rules were selected.With nursing professional knowledge taken into account,16 strong association rules were finally obtained.Conclusion:Through data mining,we can see clearly the association rules among factors of unplanned endotracheal extubation events,which provides guidance for the prevention and management system of unplanned endotrachea extubations in ICU,thus ensuring the safety of patients with endotracheal intubation.
