Evaluation of the Implementation of an Outreach Clinic for Opioid Use Disorder: Protocol for a Participatory Cocreation and Implementation Study.

Background: The opioid overdose crisis currently affecting Canada has resulted in thousands of deaths, and the COVID-19 pandemic has exacerbated the consequences of this crisis, particularly through the instability of the unregulated drug market. The province of Quebec is observing a similar pattern: the opioids consumed are more dangerous, and the number of overdoses is rising. Opioid use disorder (OUD) therefore represents a major public health issue. Offering appropriate interventions, such as opioid agonist therapy integrated into primary care, is one strategy to reduce the risk of death from overdose.

Objective: The aim of this research is to evaluate the implementation of an outreach clinic offering a low-threshold treatment program for OUD in Quebec. The secondary objective is to identify the factors that foster the participation in primary care research of people who are socially excluded and have current or past lived experience of OUD.

Methods: This study is being conducted in the Montérégie region of Quebec and comprises 3 phases: exploratory, photovoice, and participatory evaluation. The qualitative research adopts a participatory approach by involving people who are socially excluded and targeted by the outreach clinic's services (eg, people experiencing homelessness and living with OUD). A committee of peer researchers, made up of experts with current or past lived experience of OUD, will be set up and will hold 10 meetings at various stages of the research. Two participant profiles will be involved: (1) health care professionals and community workers, who will take part in semistructured interviews; and (2) people with current or past lived experience of OUD, who will take part in the photovoice sessions or peer researcher committee meetings.

Results: The peer researcher committee was formed in winter 2024, and 10 meetings had been held as of June 2025. As of August 2025, 4 photovoice sessions had been conducted, and 14 health care professionals and community workers had participated in the semistructured interviews. This study was funded in September 2022, with funding available through March 2025. Data were collected from September 2022 through June 2025. The analysis was finished in spring 2025. Results of the study are expected to be published in winter 2026.

Conclusions: The anticipated outcome is the establishment of an outreach clinic for OUD outside a major urban center, with a range of services tailored to the needs of people who are socially excluded and living with OUD. The coconstruction of this clinic in collaboration with people with current or past lived experience of OUD will enable an adequate response to the targeted population's overall health needs and help reduce the barriers to access that they may face in conventional care structures.
