Mental illness and accidental death

Abstract

BackgroundFew studies have systematically investigated the psychiatric antecedents of accidental death.AimsTo examine the patterns of psychiatric morbidities contributing to accidental death in three ethnic groups (Han, Ami and Atayal) in Taiwan.MethodA case–control psychological autopsy was conducted among 90 accidental deaths (randomly selected from a total of 413) and 180 living controls matched for age, gender, ethnicity and area of residence in Taiwan.ResultsThe risk of accidental death was significantly associated with alcohol use disorder and with other common mental disorders. When jointly considered, it was greatest when these two types of disorders co-existed, followed by common mental disorders alone. The risk of accidental death increased with the number of comorbid conditions.ConclusionsThe prevention of accidental death should be incorporated into preventive psychiatry, not just for alcohol use disorder, but also for all other common mental disorders.
