title: Comorbid substance use reduces the health care contacts of suicide attempters with schizophrenia spectrum or mood disorders.
abstract: Utilization of health care services has been found to differ between psychiatric disorders. However, the pattern of health care contacts among suicide attempters with mental disorders is not known. This study systematically investigated the pattern of health care contacts among suicide attempters with schizophrenia spectrum versus mood disorders with or without comorbid substance use disorders both before and after attempted suicide. All consecutive medically treated suicide attempters in Helsinki from January 15, 1997, to January 14, 1998, were identified (n = 1,198). Data were gathered on all their health care contacts within the 12 months before and after the index attempt. Whereas the clear majority of all suicide attempters with schizophrenia spectrum or mood disorders had a treatment contact during the 30 days following the attempt, half of those with pure substance use disorders were without any contact with health care. Comorbid substance use made treatment less likely after attempted suicide among both psychiatric disorder groups; those with schizophrenia spectrum and comorbid substance use disorders were seven times more often left without aftercare recommendation than those without substance use comorbidity. Comorbid substance use disorders among suicide attempters with schizophrenia spectrum disorders decrease the likelihood of active aftercare, despite high suicide risk.
