基于校正改良早期预警评分构建术后患者院内转运分级方案的应用研究

An application study of constructing a grading scheme for postoperative in⁃hospital transport based on the calibrated Modi⁃fied Early Warning Score

目的基于校正改良早期预警评分(Modified Early Warning Score,MEWS)构建术后患者院内转运分级方案,探讨其临床应用效果。方法选取2020年10月—2020年12月山西医科大学第一医院手术室进行院内转运的患者140例,按进入手术室时间顺序分为对照组(2020年10月1日—2020年11月15日入手术室)和试验组(2020年11月16日—2020年12月31日入手术室),每组70例。对照组按照传统转运方式进行转运,试验组基于校正MEWS构建院内转运分级方案。分析比较两组患者转运时间及转运期间不良事件发生率。结果试验组转运到病房和ICU的转运时间均短于对照组(P<0.05),转运期间病情变化类不良事件发生率、技术类不良事件发生率及不良事件总发生率均低于对照组(P<0.05)。结论基于校正MEWS构建术后患者院内转运分级方案可降低转运期间不良事件发生率,缩短转运时间。

Objective To construct an in⁃hospital transport grading scheme for postoperative patients based on the calibrated Modified Early Warning Score(MEWS)system and explore its clinical application effect.Methods A total of 140 patients who un⁃derwent postoperative transport in the operating room of the First Hospital of Shanxi Medical University from October 2020 to Decem⁃ber 2020 were selected.According to the sequence of entry into the operating room,they were divided into two groups(n=70):a control group(entry into the operating room from 1 October,2020 to 15 November,2020)and an experimental group(entry into the operating room from 16 November,2020 to 31 December,2020).Patients in the control group were transported according to the traditional trans⁃port method,while those in the experimental group were subjected to in⁃hospital transport grading scheme based on the calibrated MEWS.Both groups were compared for the time and incidence of adverse events of transport.Results The time of transferring pa⁃tients to the ward and intensive care unit(ICU)was shorter in the test group than that in the control group(P<0.05).The incidence of adverse events such as changes in disease,technical adverse event and the total incidence of adverse events during the transfer were lower in the test group than those in the control group(P<0.05).Conclusions Establishment of a grading scheme for postoperative in-hospital transport based on calibrated MEWS for clinical practice can reduce the incidence of adverse transport events and reduce transport time.
