The effect of audible alarms on anaesthesiologists' response times to adverse events in a simulated anaesthesia environment: a randomised trial.

de Man FR, Erwteman M, van Groeningen D, et al. Anaesthesia. 2014;69:598-603.

Audible alarms did not augment anesthesiologists' response time to adverse events in this simulator-based study. Frequent alarms in the anesthesia environment have likely led to clinician desensitization to them, also known as alarm fatigue. Improving the safety of hospital alarm systems has been added as a National Patient Safety Goal in the 2014 update.
