To understand how nurses respond to alerts that detect attempts to enter into electronic health records patient weights that vary significantly from previously recorded weights.
Examination of subsequent patient weights to determine if the alerts were true positive (TP) or false positive (FP), and whether nurses overrode alerts, changed their entry or quit without storing a value.
Alerts occurred 2.74%, with 41.9% TP and 58.1% FP. Nurses overrode 30.3% of TP and 97.3% of FP alerts.
The alert has an acceptable FP rate and does not appear to cause nurses to change entries to satisfy the alert. The alert improves recording of patient weights.
了解护士如何应对检测到试图输入与先前记录体重有显著差异的患者体重的警报。
检查后续患者体重，以确定警报是真阳性（TP）还是假阳性（FP），以及护士是否忽略警报、更改输入或不存储值就退出。
警报发生率为2.74%，其中41.9%为TP，58.1%为FP。护士忽略了30.3%的TP警报和97.3%的FP警报。
该警报的FP率可接受，且似乎不会导致护士为满足警报而更改输入。该警报改善了患者体重的记录。
