Embedding addiction treatment within an internal medicine resident primary care clinic was associated with increased resident confidence in diagnosing and managing substance use disorders (SUDs), according to an early evaluation from the University of Cincinnati published in Academic Medicine.¹
“In traditional training, addiction care is often taught in theory rather than practice,” lead author Michael Binder, MD, adjunct associate professor of medicine, said in a press release. “We wanted to create a model where treating substance use disorders is integrated into everyday primary care, because that’s where many patients already are.”2
- Model: integrated addiction clinic
- Setting: IM resident primary care
- Study: 15-week early evaluation
- Visits: 73 patient encounters
- Diagnoses: OUD and AUD common
- Training: confidence improved
- Medication focus: buprenorphine
- Safety outcomes: not reported
- Status: single-center US model
The report describes development of a structured addiction medicine clinic integrated into a resident ambulatory practice beginning in 2023. The clinical team included attending physicians, clinical pharmacists, addiction fellows, medical assistants, and internal medicine residents. Investigators evaluated the clinic’s first 15 weeks using patient care metrics and resident education outcomes.¹
During that initial period, the clinic recorded 73 patient visits. Opioid use disorder (OUD) and alcohol use disorder (AUD) were among the most common diagnoses. Resident physicians were surveyed before and after participation in the rotation; 11 of 18 residents completed both assessments. According to the investigators, residents reported increased confidence in diagnosing SUDs, interpreting urine drug tests, initiating and adjusting medications for OUD such as buprenorphine, and providing harm-reduction counseling.¹
The findings address a persistent mismatch between disease prevalence and treatment access. Based on the 2024 National Survey on Drug Use and Health, approximately 48.4 million Americans aged 12 years or older had an SUD, representing about 16.8% of that population, while fewer than 1 in 4 received addiction treatment.3 Primary care practices are often where patients with SUDs already receive care for other chronic conditions, but many clinicians report limited supervised outpatient experience with medications and counseling approaches used in addiction treatment.
The integrated model is notable because it places addiction care within routine internal medicine training rather than in a separate specialty setting. That structure may help normalize SUD treatment alongside diabetes, hypertension, and other chronic disease management. It may also reduce logistical and stigma-related barriers for patients who might not seek care at a specialty addiction center.
The medication focus is clinically relevant. Buprenorphine, a partial μ-opioid receptor agonist, is an evidence-based medication for OUD and can reduce illicit opioid use and overdose risk when incorporated into longitudinal care.4 Other medications used in addiction treatment include methadone and extended-release naltrexone for OUD, as well as naltrexone, acamprosate, and disulfiram for AUD. Broader recommendations also support identifying unhealthy drug use in adults when diagnosis, treatment, or referral services are available.5
For residency programs, the Cincinnati experience suggests that hands-on exposure may be more effective than didactic teaching alone for building clinical readiness. The outcome measured, however, was confidence rather than independent competency or patient-centered outcomes. The evaluation was also small, single center, and short term, with paired survey data from 11 residents. The summary did not report quantitative changes in medication initiation rates, treatment retention, substance use outcomes, overdose events, or longer-term practice patterns after graduation.
Ellen Jochum, chief physician resident who practiced in the clinic, said the experience helped translate classroom learning into outpatient primary care. “I feel much more prepared because of my experiences and now feel comfortable starting treatment for patients with a substance use disorder, knowing resources available to them,” she said in the press release.2
Next steps identified by the research team include assessing whether this type of rotation affects patient outcomes over time and whether residents continue providing addiction treatment after training. For other academic medical centers, the study offers an implementation example, but replication will require attention to faculty expertise, pharmacy support, workflow design, and sustained access to community recovery resources.
