Alarm fatigue: a patient safety concern

Area of Science:

• Biomedical Engineering
• Clinical Informatics
• Patient Safety

Background:

• A significant percentage of clinical alarms (72%-99%) are false.
• This high rate of false alarms leads to alarm fatigue, a critical issue in healthcare.
• Alarm fatigue can result in desensitization and missed alarms, with potentially fatal consequences.

Purpose of the Study:

• To address the critical problem of alarm fatigue in clinical settings.
• To review strategies aimed at reducing false alarms and their impact on patient safety.
• To emphasize the need for rigorous clinical trials to validate these strategies.

Main Methods:

• Review of existing research on clinical alarm systems and false alarm rates.
• Analysis of the causes and consequences of alarm fatigue.
• Examination of quality improvement project outcomes for strategies reducing false alarms.

Main Results:

• Quality improvement initiatives show promise in reducing false alarms.
• Effective strategies include daily electrocardiogram electrode changes, proper skin preparation, education, and customized alarm parameters.
• These interventions have the potential to decrease the burden of false alarms.

Conclusions:

• Alarm fatigue poses a significant risk to patient safety and is a recognized patient safety goal.
• Current quality improvement strategies show potential for mitigating alarm fatigue.
• Further rigorous clinical trials are essential to validate the effectiveness and safety of these strategies in reducing alarm burden.
