Evaluating the clinical impacts of healthcare alarm management systems plays a critical role in assessing newly implemented monitoring technology, exposing latent threats to patient safety, and identifying opportunities for system improvement. We describe a novel, accurate, rapidly implementable, and readily reproducible in situ simulation approach to measure alarm response times and rates without the challenges and expense of video analysis. An interprofessional team consisting of biomedical engineers, human factors engineers, information technology specialists, nurses, physicians, facilitators from the hospital's simulation center, clinical informaticians, and hospital administrative leadership worked with three units at a pediatric hospital to design and conduct the simulations. Existing hospital technology was used to transmit a simulated, unambiguously critical alarm that appeared to originate from an actual patient to the nurse's mobile device, and discreet observers measured responses. Simulation observational data can be used to design and evaluate quality improvement efforts to address alarm responsiveness and to benchmark performance of different alarm communication systems.
评估医疗保健报警管理系统的临床影响对于评估新实施的监测技术、揭示患者安全的潜在威胁以及确定系统改进机会至关重要。我们描述了一种新颖、准确、快速实施且易于重现的现场模拟方法，可在不涉及视频分析的挑战和费用的情况下测量报警响应时间和速率。一个由生物医学工程师、人为因素工程师、信息技术专家、护士、医生、医院模拟中心的协调员、临床信息专家和医院行政领导组成的跨专业团队与一家儿童医院的三个病房合作，设计并进行了模拟。使用现有的医院技术将模拟的、明确的关键警报传输到护士的移动设备，警报似乎源自实际患者，而隐蔽的观察员则测量响应。模拟观察数据可用于设计和评估质量改进工作，以解决报警响应能力，并为不同的报警通信系统的性能提供基准。
