Formative qualitative research to guide implementation of the Collaborative Care Model in a low-barrier HIV clinic.

Integrated behavioral healthcare interventions have increased access to care for people with behavioral health conditions in primary care settings. However, they have not been widely implemented in low-barrier HIV care settings where undertreated behavioral health needs remain high. We conducted a formative qualitative evaluation, using in-depth interviews with purposively selected stakeholders ( n  = 13) and patients ( n  = 16), to identify anticipated barriers and facilitators to integrating care for depression and opioid use disorder for people with HIV via the Collaborative Care Model at a low-barrier HIV clinic. Patients and stakeholders expressed their enthusiasm for the Collaborative Care Model based on its perceived relative advantage over the standard of care referral system. Availability of resources, practical concerns about perceived fit with low-barrier HIV care, and anticipated suitability given other behavioral health comorbidities and patients' complex socioeconomic needs partially tempered stakeholder perceptions of appropriateness for the Collaborative Care Model. Patients and service delivery stakeholders were receptive to the Collaborative Care Model, but felt it was moderately appropriate in the context of low-barrier HIV care, which necessitated key adaptations to core model components to improve its contextual fit.
