We argue that the optimal use of communication channels in clinical event monitors is an important design consideration for these systems. We review the state-of-the-art in selection of communication channels, including our current approach--allowing users to choose the communication channel by which the event monitor sends each notification. We describe a new approach that we are in the process of developing. In this new approach, we view event monitoring as the decision of whether and how to send new patient data to a clinician and apply the principle of maximum expected utility to this decision problem. Our initial experience with this approach suggests that notifying clinicians of normal patient data may be of high utility. We also found that methods for explanation in uncertain reasoning may be necessary in this approach.
我们认为，临床事件监测器中通信渠道的优化使用是这些系统的一项重要设计考量因素。我们回顾了通信渠道选择方面的最新技术水平，包括我们目前的方法——允许用户选择事件监测器发送每条通知所使用的通信渠道。我们描述了一种正在开发的新方法。在这种新方法中，我们将事件监测视为关于是否以及如何向临床医生发送新患者数据的决策，并将最大期望效用原则应用于这个决策问题。我们对这种方法的初步经验表明，向临床医生通报正常患者数据可能具有很高的效用。我们还发现，这种方法可能需要不确定推理中的解释方法。
