Electronic medical records (EMRs) facilitate abnormal test result communication through "alert" notifications. The aim was to evaluate how primary care providers (PCPs) manage alerts related to critical diagnostic test results on their EMR screens, and compare alert-management strategies of providers with high versus low rates of timely follow-up of results.
28 PCPs from a large, tertiary care Veterans Affairs Medical Center (VAMC) were purposively sampled according to their rates of timely follow-up of alerts, determined in a previous study. Using techniques from cognitive task analysis, participants were interviewed about how and when they manage alerts, focusing on four alert-management features to filter, sort and reduce unnecessary alerts on their EMR screens.
Provider knowledge of alert-management features ranged between 4% and 75%. Almost half (46%) of providers did not use any of these features, and none used more than two. Providers with higher versus lower rates of timely follow-up used the four features similarly, except one (customizing alert notifications). Providers with low rates of timely follow-up tended to manually scan the alert list and process alerts heuristically using their clinical judgment. Additionally, 46% of providers used at least one workaround strategy to manage alerts.
Considerable heterogeneity exists in provider use of alert-management strategies; specific strategies may be associated with lower rates of timely follow-up. Standardization of alert-management strategies including improving provider knowledge of appropriate tools in the EMR to manage alerts could reduce the lack of timely follow-up of abnormal diagnostic test results.
电子病历(EMR)通过“警报”通知促进异常检验结果的交流。本研究旨在评估初级保健提供者(PCP)如何在其 EMR 屏幕上管理与关键诊断性检验结果相关的警报,并比较具有高与低的及时随访结果率的提供者的警报管理策略。
根据之前研究中确定的及时随访警报的比率,按照及时随访警报的比率,从一家大型退伍军人事务医疗中心(VAMC)中选择了 28 名 PCP 进行了有针对性的抽样。采用认知任务分析技术,对参与者进行了有关如何以及何时管理警报的访谈,重点关注四个警报管理功能,以筛选、排序和减少 EMR 屏幕上不必要的警报。
提供者对警报管理功能的了解程度在 4%至 75%之间。近一半(46%)的提供者未使用这些功能中的任何一项,并且没有一个人使用超过两项。与及时随访率较高的提供者相比,及时随访率较低的提供者使用这四个功能的方式相似,但有一个功能(自定义警报通知)除外。及时随访率较低的提供者倾向于手动扫描警报列表,并使用其临床判断进行启发式处理警报。此外,46%的提供者使用了至少一种解决方法来管理警报。
提供者在使用警报管理策略方面存在很大的异质性;特定的策略可能与较低的及时随访率相关。包括提高提供者在 EMR 中管理警报的适当工具知识在内的警报管理策略的标准化,可能会减少异常诊断性检验结果的及时随访不足。
