Abstract
Background
Previous studies have identified factors associated with admission to hospital after suicide spectrum behaviors. In this study, we aim to identify specific factors associated with psychiatric hospitalization after self-poisoning. Given earlier findings suggesting that alcohol use disorder is not associated with hospital admission, we also aim to consider its impact, as well as blood alcohol concentrations, on hospitalization decisions after a suicide attempt.
Methods
We studied the association between demographic features, suicide intent, psychiatric characteristics and admission to hospital in self-poisoning patients in an emergency department in France.
Results
Suicide intent, a past history of suicide attempts, bipolar disorder and depression were associated with psychiatric hospital admissions. Despite alcohol use disorder being known to be associated with a suicide risk, it was not linked with psychiatric hospitalization. A positive blood alcohol concentration in the emergency department likewise had no association with admission to a psychiatric ward for inpatient care.
Conclusions
Our findings were similar to those reported for other suicide spectrum behaviors. Alcohol use disorder was not associated with admission for inpatient psychiatric care, whereas depression clearly was. The cause of this discrepancy must be determined in future research.
