Impact of an Alarm Management Protocol on Noise Pollution and Patient Safety in Intensive Care Units

The large volume of unnecessary alarms has multiple negative repercussions. Firstly, the excessively loud sound environment present in most resuscitation services causes stress and discomfort for both patients and caregivers. Additionally, nurses become desensitised and less responsive when the number of alarms is high, particularly if many of them are ultimately pointless. Finally, multiple interruptions of tasks associated with alarms that require responses are sources of errors in the execution of care and medication preparation.

These interruptions contribute to a phenomenon known as "alarm fatigue", which many authorsand health authorities consider a threat to patient safety.The intensive care unit of the Saint-Etienne University Hospital has had a long-standing interest in this topic, and has a computerized data collection tool that permits exhaustive analysis of all alarm signals originating from each resuscitation bed.

This study will enable to assess the efficacy of a restrictive protocol for managing alarms as a means of rationalizing their use.
