医疗紧急情况下的生命体征值可以帮助临床医生识别和治疗危及生命的损伤患者。然而,识别异常生命体征经常被延迟,并且可能根本没有记录值。在这项混合方法研究中,我们设计并评估了一种两阶段视觉警报方法,用于创伤复苏中的数字清单,告知用户未记录的生命体征。使用中断的时间序列分析,我们比较了在引入警报之前(两年)和之后(四个月)的文件。我们发现,引入警报导致整个干预后期间的记录增加,临床医生更早地记录生命体征。对用户的访谈和病例的视频审查表明,当临床医生较少使用检查表或将检查表放下以执行另一项活动时,警报无效。从这些发现,我们讨论的方法来设计动态团队为基础的设置警报。
Vital sign values during medical emergencies can help clinicians recognize and treat patients with life-threatening injuries. Identifying abnormal vital signs, however, is frequently delayed and the values may not be documented at all. In this mixed-methods study, we designed and evaluated a two-phased visual alert approach for a digital checklist in trauma resuscitation that informs users about undocumented vital signs. Using an interrupted time series analysis, we compared documentation in the periods before (two years) and after (four months) the introduction of the alerts. We found that introducing alerts led to an increase in documentation throughout the post-intervention period, with clinicians documenting vital signs earlier. Interviews with users and video review of cases showed that alerts were ineffective when clinicians engaged less with the checklist or set the checklist down to perform another activity. From these findings, we discuss approaches to designing alerts for dynamic team-based settings.
