BACKGROUND: Effective person-centred interventions are needed to support people living with mental-physical multimorbidity to achieve better health and wellbeing outcomes. Depression is identified as the most common mental health condition co-occurring with a physical health condition and is the focus of this intervention development study. The aim of this study is to identify the key components needed for an effective intervention based on a clear theoretical foundation, consideration of how motivational interviewing can inform the intervention, clinical guidelines to date, and the insights of primary care nurses. METHODS: A multimethod approach to intervention development involving review and integration of the theoretical principles of Theory of Planned Behavior and the patient-centred clinical skills of motivational interviewing, review of the expert consensus clinical guidelines for multimorbidity, and incorporation of a thematic analysis of group interviews with Australian nurses about their perspectives of what is needed in intervention to support people living with mental-physical multimorbidity. RESULTS: Three mechanisms emerged from the review of theory, guidelines and practitioner perspective; the intervention needs to actively 'engage' patients through the development of a collaborative and empathic relationship, 'focus' on the patient's priorities, and 'empower' people to make behaviour change. CONCLUSION: The outcome of the present study is a fully described primary care intervention for people living with mental-physical multimorbidity, with a particular focus on people living with depression and a physical health condition. It builds on theory, expert consensus guidelines and clinician perspective, and is to be tested in a clinical trial.

Background: Treatment of opioid use disorder (OUD) is highly effective, but access is limited and care is often fragmented. Treatment in primary care can improve access to treatment and address psychiatric and physical co-morbidities in a holistic, efficient, and non-stigmatizing way. The Collaborative Care Model (CCM) of behavioral health integration into primary care has been widely disseminated and shown to improve outcomes and lower costs when studied for depression, but its use in treating substance use disorders has not been well documented. Methods: We used a mixed-methods approach to examine the impact of implementing multidisciplinary treatment of OUD in our health system's five primary care clinics using the framework of the CCM, with care shared between the primary care clinician (PCP), behavioral health clinician, and medical assistant. The implementation included staff education, creation of electronic health record tools, and implementation support, and was evaluated using data from the electronic health record, the medical staff office, and a clinician survey. Results: Over the last 2 years of implementation, the number of waivered providers increased from 11 to 35, providers prescribing for 5 or more patients increased from 2 to 18, and patients initiated on buprenorphine increased from 4/month to 18/month. 180-day treatment retention was 53%, and 81% of patients had consistently negative urine drug testing. Psychiatric and medical comorbidities were common, 70 and 44%, respectively. Although PCPs who prescribed buprenorphine found working in this model enjoyable and effective, the majority of non-waivered PCPs remained reluctant to participate. Conclusions: In our experience, treatment of OUD in primary care utilizing the CCM effectively addresses OUD and commonly comorbid anxiety and depression, and leads to an expansion of treatment. Successful implementation of OUD treatment requires addressing negative attitudes and perceptions.
