BACKGROUND: Substance use is prevalent in Canada, yet treatment is inaccessible. The Rapid Access to Addiction Medicine (RAAM) clinic opened at the University Health Network (UHN) in January 2018 as part of a larger network of addictions clinics in Toronto, Ontario, to enable timely, low barrier access to medical treatment for substance use disorder (SUD). Patients attend on a walk-in basis without requiring an appointment or referral. We describe the RAAM clinic model, including referral patterns, patient demographics and substance use patterns. Secondary outcomes include retention in treatment and changes in both self-reported and objective substance use. METHODS: The Electronic Medical Record at the clinic was reviewed for the first 26 weeks of the clinic's operation. We identified SUD diagnoses, referral source, medications prescribed, retention in care and self-reported substance use. RESULTS: The clinic saw 64 unique patients: 66% had alcohol use disorder (AUD), 39% had opiate use disorder (OUD) and 20% had stimulant use disorder. Fifty-five percent of patients were referred from primary care providers, 30% from the emergency department and 11% from withdrawal management services. Forty-two percent remained on-going patients, 23% were discharged to other care and 34% were lost to follow-up. Gabapentin (39%), naltrexone (39%), and acamprosate (15%) were most frequently prescribed for AUD. Patients with AUD reported a significant decrease in alcohol consumption at their most recent visit. Most patients (65%) with OUD were prescribed buprenorphine, and most patients with OUD (65%) had a negative urine screen at their most recent visit. CONCLUSION: The RAAM model provides low-barrier, accessible outpatient care for patients with substance use disorder and facilitates the prescription of evidence-based pharmacotherapy for AUD and OUD. Patients referred by their primary care physician and the emergency department demonstrated a reduction in median alcohol consumption and high rates of opioid abstinence.

A significant percentage of patients with psychiatric disorders are exclusively seen for health-care services by primary care physicians. To address the mental health needs of such patients, collaborative models of care were developed including the embedded psychiatry consult model which places a consultant psychiatrist on-site to assist the primary care physician to recognize psychiatric disorders, prescribe psychiatric medication, and develop management strategies. Outcome studies have produced ambiguous and inconsistent findings regarding the impact of this model. This review examines a primary care-embedded psychiatric consultation service in place for nine years in a family medicine residency program. Psychiatric consultants, family physicians, and residents actively involved in the service participated in structured interviews designed to identify the clinical and educational value of the service. The benefits and limitations identified were then categorized into physician, consultant, patient, and systems factors. Among the challenges identified were inconsistent patient appointment-keeping, ambiguity about appropriate referrals, consultant scope-of-practice parameters, and delayed follow-up with consultation recommendations. Improved psychiatric education for primary care physicians also appeared to shift referrals toward more complex patients. The benefits identified included the availability of psychiatric services to underserved and disenfranchised patients, increased primary care physician comfort with medication management, and improved interprofessional communication and education. The integration of the service into the clinic fostered the development of a more psychologically minded practice. While highly valued by respondents, potential benefits of the service were limited by residency-specific factors including consultant availability and the high ratio of primary care physicians to consultants.
