[Benefit of mortality and morbidity reviews in psychiatry].

A mortality and morbidity (M&M) review consists in analysing, collectively and retrospectively, the cases of patients whose evolution has been marked by a complication or death. This analysis must question whether such an outcome could have been avoided, making it possible to identify the causes and correct the factors having contributed to its occurrence. After a presentation of the methodological and organisational principles, as well as the M&M reviews carried out in France, attention is turned to those performed in psychiatry and identifying the main perspectives for the discipline.
