Reduction of clinical alarms is a priority due to alarm fatigue and the high incidence of nonactionable alarms, especially those generated from physiological monitors. However, research on infusion pump alarm types and frequencies is limited. The purpose of this study was to establish a baseline for infusion pump alarm frequencies and duration in the hospital setting. Frequency and duration of alarms across 29 hospitals using 11,410 infusion pumps revealed 987,240 alarms associated with 568,164 infusions during a consecutive 60-day period. Pump alarms accounted for only 0.8% of infusion time, with an average of 1.74 alarms per delivery and 0.18 alarms per hour. Average alarm duration was 0:02:38 (h:min:s), with 60% of alarms being addressed within 0:01:08. The most frequent alarms were keep vein open (33.77%), hold expired (27.18%), and downstream occlusion (22.94%). The medical/surgical and intensive care unit (ICU) care areas had the highest number of alarms (41.66% and 39.70% of total alarms, respectively), but pediatrics/neonatal ICU had the highest frequency of alarms per delivery (4.91). Intravenous fluids accounted for 47.16% of total alarms, with an average of 3.03 alarms per delivery, whereas parenteral nutrition and propofol had 6.77 and 6.74 average alarms per delivery, respectively. A higher average number of alarms per delivery occurred on Saturdays (1.74) and Sundays (1.73) compared with weekdays. Infusion pump alarm data collected and analyzed were sufficient to establish a reasonable baseline of infusion pump alarm types and relative frequencies for the device.
由于警报疲劳以及不可操作警报的高发生率,尤其是生理监测仪产生的警报,减少临床警报成为当务之急。然而,关于输液泵警报类型和频率的研究有限。本研究的目的是为医院环境中输液泵的警报频率和持续时间建立一个基线。在连续60天的时间里,对29家医院使用的11410台输液泵的警报频率和持续时间进行了调查,结果显示,与568164次输液相关的警报有987240次。泵警报仅占输液时间的0.8%,每次输液平均有1.74次警报,每小时有0.18次警报。平均警报持续时间为0:02:38(小时:分钟:秒),60%的警报在0:01:08内得到处理。最常见的警报是保持静脉通畅(33.77%)、暂停过期(27.18%)和下游阻塞(22.94%)。内科/外科和重症监护病房(ICU)的警报数量最多(分别占总警报数的41.66%和39.70%),但儿科/新生儿ICU每次输液的警报频率最高(4.91)。静脉输液占总警报数的47.16%,每次输液平均有3.03次警报,而肠外营养和丙泊酚每次输液的平均警报数分别为6.77和6.74。与工作日相比,周六(1.74)和周日(1.73)每次输液的平均警报数更高。收集和分析的输液泵警报数据足以建立该设备合理的输液泵警报类型和相对频率基线。
