Brief summary
Resuscitation patients are monitored for various physiological parameters. When these parameters exceed abnormal thresholds, an audible alarm is triggered. Given the complexity of physiological situations and the number of monitored parameters, the number of alarms within an intensive care unit is significant. In the literature, the number ranges from 100 to 350 alarms per patient per day. Among these alarms, 74 to 99% are deemed irrelevant as they provide false or insignificant information. This study will enable to assess the efficacy of a restrictive protocol for managing alarms as a means of rationalizing their use.
Detailed description
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.

| Evaluation of patient perception using the Discomforts of intensive care patients questionnaire | 1 month | Evaluation of patient perception using the Discomforts of intensive care patients questionnaire. The Discomforts of intensive care patients questionnaire validated in intensive care and in French, assesses 16 sources of discomfort, including noise. The questionnaire is given to patients before they are discharged from intensive care. The questionnaire scores range from 0 to 100, with the highest score indicating maximum discomfort. |
| Sound level measurement using a sound level meter | 7 days | Sound level measurement using a sound level meter. A measuring instrument will be placed in the rooms of the patients included during the day for 4 consecutive hours on day 1, 3 and 7. This part of the study will be carried out in conjunction with occupational medicine and the Quality, Risk Management and Patient Experience Department, which already carry out this type of measurement as part of their assessment of working conditions. |
