Computerized physician order entry (CPOE) has had demonstrated benefits in error reduction and guideline adherence, but its implementation has often been complicated by disruptions in established workflow processes. We conducted an observational study of the healthcare team in an intensive care unit after the implementation of mandatory CPOE. We found that policies designed to increase flexibility and safety led to an increased coordination load on the healthcare team, and created opportunities for new sources of error. We attribute this in part to implicit assumptions in the CPOE system design that execution of physician orders is a linear work process. Observational workflow studies are an important tool to understand how to redesign CPOE systems so as to avoid harm and achieve the full potential of benefit for improved patient safety.
计算机化医师医嘱录入（CPOE）已被证明在减少错误和遵循指南方面具有益处，但其实施往往因既定工作流程的中断而变得复杂。在实施强制性CPOE后，我们对一家重症监护病房的医疗团队进行了一项观察性研究。我们发现，旨在提高灵活性和安全性的政策导致医疗团队的协调负担增加，并为新的错误来源创造了机会。我们将此部分归因于CPOE系统设计中的隐含假设，即医师医嘱的执行是一个线性工作流程。观察性工作流程研究是了解如何重新设计CPOE系统以避免伤害并充分发挥其对改善患者安全的潜在益处的重要工具。
