The aim of this study was to describe computational ethnography as a contemporary and supplemental methodology in EHR workflow analysis and the relevance of this method to nursing research.
We explore the use of audit logs as a computational ethnographic data source and the utility of data mining techniques, including sequential pattern mining (SPM) and Markov chain analysis (MCA), to analyze nurses' workflow within the EHRs. SPM extracts frequent patterns in a given transactional database (e.g., audit logs from the record). MCA is a stochastic process that models a sequence of states and allows for calculating the probability of moving from one state to the next. These methods can help uncover nurses' global navigational patterns (i.e., how nurses navigate within the record) and enable robust workflow analyses.
We demonstrate hypothetical examples from SPM and MCA, such as (a) the most frequent sequential pattern of nurses' workflow when navigating the EHR using SPM and (b) transition probability from one record screen to the next using MCA. These examples demonstrate new methods to address the inflexibility of current approaches used to examine nursing EHR workflow.
Within a clinical context, the use of computational ethnographic data and data mining techniques can inform the optimization of the EHR. Results from these analyses can be used to supplement the data needed in redesigning the EHR, such as organizing and combining features within a screen or predicting future navigation to improve the record that nurses use.
本研究旨在描述计算民族志作为电子病历工作流程分析的一种当代和补充方法,以及该方法与护理研究的相关性。
我们探索了使用审计日志作为计算民族志数据源,以及数据挖掘技术(包括序列模式挖掘(SPM)和马尔可夫链分析(MCA))在电子病历中分析护士工作流程的效用。SPM 从给定的事务性数据库(例如,来自记录的审计日志)中提取频繁模式。MCA 是一种随机过程,用于对状态序列建模,并允许计算从一个状态转移到下一个状态的概率。这些方法可以帮助揭示护士的全局导航模式(即护士在记录中导航的方式),并实现强大的工作流程分析。
我们展示了 SPM 和 MCA 的假设示例,例如(a)使用 SPM 导航电子病历时护士工作流程的最常见顺序模式,以及(b)使用 MCA 从一个记录屏幕到下一个记录屏幕的转移概率。这些示例展示了新的方法来解决当前用于检查护理电子病历工作流程的方法的灵活性问题。
在临床环境中,使用计算民族志数据和数据挖掘技术可以为优化电子病历提供信息。这些分析的结果可用于补充重新设计电子病历所需的数据,例如在屏幕内组织和组合功能,或预测未来导航以改进护士使用的记录。
