The study sought to identify collaborative electronic health record (EHR) usage patterns for pediatric trauma patients and determine how the usage patterns are related to patient outcomes.
A process mining-based network analysis was applied to EHR metadata and trauma registry data for a cohort of pediatric trauma patients with minor injuries at a Level I pediatric trauma center. The EHR metadata were processed into an event log that was segmented based on gaps in the temporal continuity of events. A usage pattern was constructed for each encounter by creating edges among functional roles that were captured within the same event log segment. These patterns were classified into groups using graph kernel and unsupervised spectral clustering methods. Demographics, clinical and network characteristics, and emergency department (ED) length of stay (LOS) of the groups were compared.
Three distinct usage patterns that differed by network density were discovered: fully connected (clique), partially connected, and disconnected (isolated). Compared with the fully connected pattern, encounters with the partially connected pattern had an adjusted median ED LOS that was significantly longer (242.6 [95% confidence interval, 236.9-246.0] minutes vs 295.2 [95% confidence, 289.2-297.8] minutes), more frequently seen among day shift and weekday arrivals, and involved otolaryngology, ophthalmology services, and child life specialists.
The clique-like usage pattern was associated with decreased ED LOS for the study cohort, suggesting greater degree of collaboration resulted in shorter stay.
Further investigation to understand and address causal factors can lead to improvement in multidisciplinary collaboration.
本研究旨在确定儿科创伤患者协作式电子健康记录(EHR)使用模式,并确定这些使用模式与患者结局的关系。
本研究将基于流程挖掘的网络分析应用于 EHR 元数据和创伤登记数据,纳入了一家一级儿科创伤中心收治的轻度创伤患儿队列。EHR 元数据被处理成一个事件日志,该日志根据事件时间连续性中的空白进行分段。通过在同一事件日志段内创建功能角色之间的边,为每次就诊构建一个使用模式。使用图核和无监督谱聚类方法对这些模式进行分类。比较了组间的人口统计学、临床和网络特征以及急诊科(ED)的住院时间(LOS)。
发现了三种使用模式,它们在网络密度上存在差异:完全连接(团)、部分连接和不连接(孤立)。与完全连接模式相比,部分连接模式的就诊具有更长的调整后 ED LOS(242.6 [95%置信区间,236.9-246.0] 分钟 vs. 295.2 [95%置信区间,289.2-297.8] 分钟),更多见于日间和工作日就诊,涉及耳鼻喉科、眼科服务和儿童生活专家。
团状样使用模式与研究队列的 ED LOS 降低相关,表明更高程度的协作可导致住院时间缩短。
进一步的研究可以深入了解并解决因果因素,从而提高多学科协作水平。
