Objective: People with severe mental illness (SMI) have often comorbid alcohol and other substance disorders but substantial barriers to addiction care remain. The study is aimed at describing correlates associated with dependence and with treatment for substance use among people with SMI and comorbid substance disorders cared in community mental health teams (CMHTs).
Methods: This study capitalized on data from a national survey on comorbid severe mental and substance use disorders, among 2235 subjects in 42 CMHTs nationwide.
Results: 26% of people with SMI and comorbid misuse suffered from dependence on alcohol and 21% on any other substance. Use of opioids, liver diseases, involvement with criminal justice system, but also area of residence, all were associated with dependence in people with SMI. As regards treatment for substance use, only 50% of comorbid people with SMI were treated by specialist services in the past 12 months. This was associated with opioids and cocaine use, as well as with liver diseases, and involvement with criminal justice. People with schizophrenia and those living in Central and Southern Italy, had the lowest chances to be treated for their comorbid substance use disorder.
Conclusions: There are extensive unmet treatment needs among comorbid individuals with SMI. Better integration of substance abuse and mental health care systems, and more effective reciprocal referral procedures, are needed.
