Introduction: This brief report describes how a family medicine residency practice (FMRP) leveraged a resident-led quality improvement project and a grant-funded Addiction Integrated Care Team (AICT) to initiate an office-based opioid treatment (OBOT) program to provide medications for opioid use disorder during the COVID-19 pandemic. Method: In 2020, the practice experienced four disruptors that shifted motivation for practice development: (a) The COVID-19 pandemic demanded rapid change in primary care processes/staffing, including pivoting to telehealth/remote practice. (b) The practice’s transition to a federally qualified community health center model meant a shift in organizational priorities that required offering OBOT services. (c) External grant resources became available through the AICT program to support practice core for OBOT, and 10 implementation strategies were utilized. (d) A resident champion implemented an OBOT quality improvement project. Results: These efforts resulted in the practice offering the OBOT program and 18 patients receiving OBOT from January 2020 to February 2021, with 10 of 18 patients engaged for 12 months or longer. Further, the cumulative adoption and reach from January 2020 through September 2022 was 15 faculty and 14 residents becoming prescribers and 101 patients served within the OBOT program, respectively. Discussion: FMRPs striving for significant practice transformation, such as implementing an OBOT program during a pandemic, may benefit from synergistic guidance and resources including established theory, strategies from the implementation science literature, and resident-led quality improvement efforts.
