We aimed to examine the effects of information access cost and accountability on medical residents' information retrieval strategy and performance during prehandover preparation.
Prior studies observing doctors' prehandover practices witnessed the use of memory-intensive strategies when retrieving patient information. These strategies impose potential threats to patient safety as human memory is prone to errors. Of interest in this work are the underlying determinants of information retrieval strategy and the potential impacts on medical residents' information preparation performance.
A two-step research approach was adopted, consisting of semistructured interviews with 21 medical residents and a simulation-based experiment with 32 medical residents.
The semistructured interviews revealed that a substantial portion of medical residents (38%) relied largely on memory for preparing handover information. The simulation-based experiment showed that higher information access cost reduced information access attempts and access duration on patient documents and harmed information preparation performance. Higher accountability led to marginally longer access to patient documents.
It is important to understand the underlying determinants of medical residents' information retrieval strategy and performance during prehandover preparation. We noted the criticality of easy access to patient documents in prehandover preparation. In addition, accountability marginally influenced medical residents' information retrieval strategy.
Findings from this research suggested that the cost of accessing information sources should be minimized in developing handover preparation tools.
我们旨在研究信息获取成本和问责制对住院医师在交接班前准备期间信息检索策略和表现的影响。
先前观察医生交接班前做法的研究发现,在检索患者信息时会使用依赖记忆的策略。由于人类记忆容易出错,这些策略对患者安全构成潜在威胁。本研究关注的是信息检索策略的潜在决定因素以及对住院医师信息准备表现的潜在影响。
采用了两步研究方法,包括对21名住院医师进行半结构化访谈以及对32名住院医师进行基于模拟的实验。
半结构化访谈显示,相当一部分住院医师(38%)在准备交接班信息时很大程度上依赖记忆。基于模拟的实验表明,较高的信息获取成本减少了对患者文件的信息获取尝试和获取时长,并损害了信息准备表现。较高的问责制导致对患者文件的获取时间略长。
了解住院医师在交接班前准备期间信息检索策略和表现的潜在决定因素很重要。我们注意到在交接班前准备中方便获取患者文件的关键性。此外,问责制对住院医师的信息检索策略有轻微影响。
本研究结果表明,在开发交接班准备工具时,应尽量降低获取信息源的成本。
