Patient-Centered Models of HCV Care for People who Inject Drugs

Role: Co-investigator
This study aims to explore the best model of care for treating hepatitis C (HCV) in people who inject drugs. This research will compare methods of HCV treatment (directly-observed therapy to patient navigator). Outcomes to be evaluated will include treatment effectiveness (cure) and reinfection rates. This is a national study involving eight US cities (New York, Baltimore, Providence, Boston, Cincinnati, Seattle, San Francisco, and Albuquerque) and up to 1,000 subjects recruited from methadone clinics and community health centers.

Role: Co-investigator

Mentoring the next generation of addiction clinician scientists while responding to the opioid epidemic

Role: Mentor

University of Washington Provider’s Clinical Support System – Universities

Role: Principal Investigator
The UW-PCSS-U project will provide DATA waiver training to medical students and residents with the goal of encouraging fledgling physicians to utilize buprenorphine in the treatment of opioid use disorder (OUD). To accomplish this goal, the project builds on the institution’s existing curriculum that addresses pain and addiction, including pre-clinical and clinical experiences. The program will include an evaluation of provider outcomes (achieving waivers and prescribing).

Previous Funding

SAMHSA Medication-Assisted Treatment (MAT)

The MAT Prescription Drug and Opioid Addiction project provides clinical services centered around buprenorphine treatment through the Adult Medicine Clinic at Harborview Medical Center for patients suffering from opioid use disorders. The program is based on a collaborative care model driven by a nurse care manager that optimizes physician effort.

Advancing Clinical Research Training within Addiction Residency Programs
