Predictors of emergency department visits for suicidal ideation and suicide attempt.

OBJECTIVES

This study investigated predictors of emergency department (ED) visits for suicidal ideation and suicide attempt in 2014-15 among patients at six Quebec emergency departments (ED), using administrative data.

METHODS

Participants (n = 11,778) used ED for suicidal ideation (30.4%); suicide attempt (7.0%); or other reasons (61.7%). A multinomial logistic regression was performed using variables described by the Andersen Behavioral Model.

RESULTS

The odds of ED visits for suicidal ideation or suicide attempt was high for adjustment disorders, personality disorders, and prior ED consultations for mental health (MH) reasons, but lower for schizophrenia spectrum and other psychotic disorders, illness acuity levels 3-5 (low severity), and 3+ consultations with outpatient psychiatrists. The odds of visiting ED for suicidal ideation increased in depressive disorders, and in the 12-17 year age range, but decreased in association with 1-2 outpatient psychiatrist consultations. The odds of suicide attempt also increased with alcohol use disorders and drug-induced disorders, but decreased with specific MH interventions at local community health services centers.

CONCLUSION

increasing access to ambulatory care, and care continuity in outreach programs for acute MH disorders, including substance-related disorders, may reduce ED visits for suicidal ideation and suicide attempt, while improving overall service delivery.
