Despite its many advantages, using a computerized patient record is still considered as a time consuming activity for care providers. In numerous situations, time is wasted because of the lack of interoperability between systems. In this study, we aim to assess the time gains that nursing teams could achieve with a tightly integrated computerized order entry system. Using a time-motion method, we compared expected versus effective time spent managing laboratory orders for two different computerized systems: one integrated, the other not integrated. Our results tend to show that nurses will complete their task an average of five times faster than their expected performance (p<0.001). We also showed that a tightly integrated system provides a threefold speed gain for nurses compared to a non-integrated CPOE with the laboratory information system (p<0.001). We evaluated the economic benefit of this gain, therefore arguing for a strong interoperability of systems, in addition to patient safety benefits.
尽管计算机化患者记录有诸多优点，但对于护理人员来说，使用它仍被视为一项耗时的工作。在许多情况下，由于系统之间缺乏互操作性，时间被浪费了。在本研究中，我们旨在评估护理团队通过紧密集成的计算机化医嘱录入系统能够节省的时间。我们采用时间动作研究方法，比较了使用两种不同计算机系统管理实验室医嘱的预期时间与实际有效时间：一种是集成系统，另一种是非集成系统。我们的结果表明，护士完成任务的平均速度比预期快五倍（p<0.001）。我们还表明，与未与实验室信息系统集成的计算机化医嘱录入系统相比，紧密集成的系统能使护士的工作速度提高两倍（p<0.001）。我们评估了这一效率提升所带来的经济效益，因此除了患者安全益处外，还主张系统具备强大的互操作性。
