The patient monitors were used to explore the alarm fatigue in a cardiac care unit and to investigate the awareness and reaction of nurse to alarms.
A semi-structured survey was taken to acquire nurses' feeling and knowledge about monitoring alarm. Three full-time researchers were scheduled to track the alarms with annotations, and analyze the alarm data of 12 patient monitors using central monitoring system.
A total of 72 310 unique alarms occurred in the 67-day study period. About 75.7% of them were physiological alarms and less than 10% of medium-low alarms were false positives. The average alarm rate was 128 alarms/patient-day.
There remains alarm fatigue in CCU, the alarm accuracy has improved than the past by applying new technologies. In some cases, clinicians will pay more attention to trend alarm and combination alarm.
使用患者监测设备探究心脏监护病房中的警报疲劳情况，并调查护士对警报的认知和反应。
采用半结构化调查以获取护士对监测警报的感受和知识。安排三名全职研究人员对警报进行标注跟踪，并使用中央监测系统分析12台患者监测设备的警报数据。
在为期67天的研究期间共发生了72310次独特警报。其中约75.7%为生理警报，中低级别警报的误报率不到10%。平均警报率为128次/患者日。
心脏监护病房中仍然存在警报疲劳，通过应用新技术，警报准确性较过去有所提高。在某些情况下，临床医生会更加关注趋势警报和组合警报。
