Background. The number of Vermonters seeking treatment for opioid abuse is increasing. The Hub and Spoke model seeks to address the opioid crisis by connecting specialty treatment centers with outpatient office-based opioid treatment (OBOT) providers. The goal of this project was to identify physician barriers to providing OBOT in Chittenden County, Vermont. Methods. We performed structured interviews with 25 primary care providers (PCPs) in Chittenden County, Vermont. Eleven were waivered OBOT providers; 14 were not. We emphasized questions assessing barriers to expanding OBOT capacity. The results were analyzed using the Grounded Theory approach. Results. Of the 25 PCPs interviewed, 7 (28%) were in private practice and 11 (44%) provided OBOT. The mean number of years in practice was 16.5 (range: 1-38), and the average OBOT patient panel size was 30 (range 1-112). The five most frequently reported barriers were: insufficient state logistical support, challenging patient population, practice infrastructure/capacity, time, and provider fears/concerns. Seventy-nine percent of non-prescriber PCPs said that they would provide OBOT if the identified barriers were removed. Discussion/Recommendations. Non-OBOT providers more frequently reported that OBOT patients were challenging. OBOT providers more frequently acknowledged the stigma associated with OBOT. Both groups desired increased state support for OBOT. We therefore recommend the following: 1) Increased state support/resources for OBOT; 2) Mentorship of new OBOT providers by experienced OBOT providers; 3) Generation of OBOT best practice guidelines for PCPs. These strategies have potential to increase capacity for office-based opioid treatment in Vermont.
