Background and Goal of Study: The systematic collection and analysis of incidents is highly recommended. The purpose of this study is to assess continuously collected events and to compare their associated factors.

Materials and Methods: From 01/2000 to 04/2004, every anesthesia is described with the patient features, the anesthetic technique and the occurrence of events (out of a list of 58), using a preformatted sheet then scanned and recorded in a data base. The herein analyzed events are bradycardia (brad), hypotension (hTA), hypoxemia SpO2 < 90% (hO2), bronchospasm (bronsp), unexpected difficult intubation (UDI), esophageal intubation (esint), regional anesthesia failure (RAf). A multivariate analysis was performed to assess the associations between these factors and age in quartile (Q), Post Anesthesia Care Unit length of stay (Q), surgery duration (Q), ASA physical status, emergency (versus elective surgery), number of spots on the responsibility of 1 anesthesiologist.

Results and Discussions: All the anesthesia procedures have been analyzed (n = 19118). The odds ratio (OR) are:

Reference group (OR = 1) is not displayed. Age is strongly associated with hTA. OR are very dissimilar, some differences (hTA, brad vs the others) can be explained by the event collection method. May be organizational events could be better quality indicators in anesthesia practice.

Conclusion: Events should be studied separately (to adjust the size of the population exposed to the risk) and more clearly defined to become really relevant indicators.
