Opioid Use Disorder Among Clients of Community Mental Health Clinics: Prevalence, Characteristics, and Treatment Willingness

OBJECTIVE

The authors examined the prevalence of co-occurring opioid use disorder and willingness to engage in treatment among clients of eight Los Angeles County Department of Mental Health outpatient clinics.

METHODS

Adults presenting for an appointment over a 2-week period were invited to complete a voluntary, anonymous health survey. Clients who indicated opioid use in the past year were offered a longer survey assessing probable opioid use disorder. Willingness to take medication and receive treatment also was assessed.

RESULTS

In total, 3,090 clients completed screening. Among these, 8% had a probable prescription (Rx) opioid use disorder and 2% a probable heroin use disorder. Of the clients with probable Rx opioid use or heroin use disorder, 49% and 25% were female, respectively. Among those with probable Rx opioid use disorder, 43% were Black, 33% were Hispanic, and 12% were White, and among those with probable heroin use disorder, 24% were Black, 22% were Hispanic, and 39% were White. Seventy-eight percent of those with Rx opioid use disorder had never received any treatment, and 82% had never taken a medication for this disorder; 39% of those with heroin use disorder had never received any treatment, and 39% had never received a medication. The strongest predictor of willingness to take a medication was believing that it would help stop opioid use (buprenorphine, β=13.54, p=0.003, and naltrexone long-acting injection, β=15.83, p<0.001).

CONCLUSIONS

These findings highlight the need to identify people with opioid use disorder and to educate clients in mental health settings about medications for these disorders.

Dual diagnosis: management within a psychosocial context

Recent developments in UK government policy have highlighted the unmet needs of people with dual diagnosis (comorbidity of substance misuse and psychiatric disorder, particularly severe mental illness). Advances in assessment techniques and diagnostic practice have informed the treatment of comorbidity and improved its outcome. There is growing evidence for the effectiveness of psychosocial interventions such as motivational interviewing and cognitive–behavioural therapy, mostly from US studies. However, within the secondary care provided by addiction and general psychiatric services there are serious implementation barriers related to service organisation, staffing levels, training and – most importantly – the difficulties of engaging people with severe mental illness and comorbid substance misuse in treatment. The evidence for the effectiveness of psychosocial treatments and models of service is reviewed and challenges for optimal practice in the UK are highlighted.

Management of alcohol use disorders

Welcome to the third module in our Continuing Professional Development Section (CPD). CPD is now a key element in the clinical activity of all health professionals and a cornerstone of good clinical governance throughout mental health services. This section of the Irish Journal of Psychological Medicine will provide CPD modules dedicated to key topics in mental health care. In order to assist learning and self-assessment, multiple choice questions will be provided at the end of each module.

This module and its multiple choice questions are available online on the website of the Irish Journal of Psychological Medicine (www.ijpm.org). The CPD policy of the College of Psychiatry of Ireland indicates that psychiatrists who participate in suitable online learning which fits the criteria for CPD may claim CPD points under the Personal CPD category (up to a maximum of 5 points per year).

We are confident that this CPD Section of the Irish Journal of Psychological Medicine will prove to be a valuable resource for consultant psychiatrists, psychiatric trainees and all journal readers. We welcome feedback from readers and, especially, any suggestions for topics to be covered in future CPD modules. Suggestions should be emailed to: psychological@medmedia.ie
