Factors associated with hospitalization after suicide spectrum behaviors: results from a multicenter study in Spain

The objective of this study was to identify factors associated with hospital admission after suicide spectrum behaviors. Patients' characteristics, the nature of the suicidal behavior, admission rates between centers, and factors associated with admission have been examined in suicide spectrum presentations to emergency departments in 3 Spanish cities. The intent of the suicidal behavior had the greatest impact on hospitalization. Older age, living alone, self-harm method not involving drug overdose, previous history of suicide spectrum behaviors, and psychiatric diagnosis of schizophrenia, mood, or personality disorder were independently associated with being admitted. There was a 3-fold between-center difference in the rate of hospitalization. Widespread differences in the rate of hospitalization were primarily accounted for by characteristics of the individual patients and their suicidal behavior.
