Dr. Knudsen’s research focuses on the addiction treatment system, both as organizational contexts for health care and as the workplaces of addiction counselors. Drawing on perspectives within implementation science, her recent work has focused on the organizational adoption of treatment innovations with an emphasis on the availability of pharmacotherapies within the American treatment system, particularly medications for opioid use disorder (MOUD). She is currently a Co-Investigator for the University of Kentucky’s $87 million grant within the HEALing Communities Study (HCS), which is a translational research effort to expand the adoption and implementation of evidence-based practices to prevent opioid overdose fatalities in 16 Kentucky communities (and a total of 67 communities in four states). For HCS, she is leading the national Implementation Science Work Group which has been tasked with developing measures to identify barriers and facilitators to community-level responses to address the opioid epidemic. For the Kentucky HCS site, she leads a team of 7 implementation facilitators, who are using implementation strategies to increase uptake of overdose education and naloxone distribution in a range of settings (e.g., primary care clinics, treatment programs, syringe service programs) and the implementation of care navigation and peer recovery support in programs that deliver MOUD. She recently led a project, funded by the National Institute on Drug Abuse (NIDA), on the impact of the Affordable Care Act on the availability and quality of buprenorphine treatment for patients with opioid use disorders.
