Alarm fatigue is sensory overload nurses experience when exposed to the nonstop beeping of monitors, pumps and other machines in hospital rooms. The result is not only a desensitization to alarms, but also missed alerts.
Why are alarms missed? Because 72-99% of them are false, leading to delayed reactions or ignoring them completely.
Alarm fatigue isn’t a new condition. According to Nurse.org, the Joint Commission began looking at it in 2013. In 2014, alarm management became a National Patient Safety Goal. Each year since, it has continued to be a National Patient Safety Goal because there continues to be sentinel events related to alarm management and fatigue.
During the past decade, research found:
- The Food and Drug Administration reported more than 560 alarm-related deaths in the United States between 2005 and 2008.
- One study showed more than 85% of all alarms in a particular unit were false.
- One hospital reported about 1 million alarms going off in just one week.
- A children’s hospital reported 5,300 alarms in a day — 95% of which were false.
- A hospital reported at least 350 alarms per patient per day in the intensive care unit.
Why were the numbers so large? According to the Joint Commission’s 2013 research, factors that contributed to alarm fatigue in the hospital included:
- Alarm parameter thresholds set too tight
- Alarm settings not adjusted to each patient’s needs
- Poor electrode practices resulting in frequent false alarms
- Inability of staff to hear alarms or detect where an alarm is coming from
- Inadequate staff training
- Inadequate staff response
- Alarm malfunction
In its 2019 National Patient Safety Goals, the Joint Commission recommended standardization, but with the ability to customize approaches for individual patients, groups or units.
The Association for the Advancement of Medical Instrumentation’s recommendations, Nurse.org reported, included:
- Have an alarm-management process in place
- Review and adjust default parameter settings and ensure appropriate settings
- Determine where and when alarms might not be needed
- Create procedures that allow staff to customize alarms
- Make sure all equipment is maintained properly
Hospitals nationwide have been implementing changes to reduce the number of false alarms at their facilities. Boston Medical Center, for example, adjusted the default heart rate settings to align with each patient’s condition, reducing the number of alarms by 60%.
Cincinnati Children’s Hospital Medical Center’s changes reduced daily per patient alarms from 180 to 40, with false alarms falling from 95% to 50%.
