Déclaration informatisée des évènements indésirables : un outil pour les comités de retour d'expérience en anesthésie

Analyzing anaesthesia adverse events reports over a 50 months period. Monocentric retrospective study. We evaluated number of reports, patients characteristics, the place and moment of the adverse event, and its consequences. Numerical data were compared with a Mann and Whitney test or a Chi2 test. A P-value < 0.05 was considered as statistically significant. Two hundred and sixty-eight adverse events were reported over the study period. It represented 1.1% of anaesthesia activity. Median patient age was 61 years old, and median ASA score was 2. Most of the statements were made by anaesthesiologists. Adverse events occurred mainly between 8 am and 2 pm, and in operating room. They were due to general dysfunctions in 29.1% of cases. They were considered severe in 7.8% of cases. Severe adverse events were associated with a higher ASA score. Adverse events occurred mainly in working hours and in operating room. They are mostly non severe. The role of the experience feedback committee is to analyze adverse effects to learn regarding the causation of the incident prevent it from recurring. As a result, an efficient reporting system is needed. An informatics based reporting system may be a useful tool because it may facilitate the reporting.
