Addiction Medicine Fellowship - The purpose of the Geisinger Addiction Medicine Fellowship grant application is to train 20 addiction medicine fellows in our ACGME accredited Addiction Medicine Fellowship program to practice as addiction medicine specialists in medically underserved, community-based settings that integrate primary care with mental health disorder and substance use disorder (SUD) prevention and treatment services. Training will include prevention and treatment in medically underserved, community-based settings, including in rural areas that have limited access to SUD treatment. The Geisinger Addiction Medicine Fellowship will 1) Increase the number of fellows by 20 trained to practice addiction medicine in rural and other medically underserved community-based settings. 2) Enhance 4 partnerships with clinical rotations sites in rural and medically underserved areas, that focus on the integration of primary care with mental health and SUD prevention and treatment services. 3) Increase fellows’ knowledge and ability to assist their patients with referrals to navigate the legal and social systems related to patients’ clinical or care needs. 4) Increase awareness of the specialty and reduce provider stigma to increase the number of physicians interested in pursuing careers in addiction medicine through the provision of clinical rotations lead by fellows teaching medical residents to practices in addiction medicine and through education and consultation. The Geisinger Addiction Medicine Fellowship will continue to train physicians in rotation sites in high poverty areas. Specifically, 64% of rotation site locations are in high poverty areas. In the Northeast training track 60% of rotation sites are in Medically Underserved Areas and 8% are in rural areas. In the Central training track 60% of rotation sites are considered rural sites while 8% are in Medically Underserved Areas. Therefore, Geisinger is requesting Priority 3: Rural, Tribal or Underserved Communities. The Geisinger Addiction Medicine Fellowship will deliver experiential clinical training that develops competencies in integrated, interprofessional team-based care, focused on at risk populations for OUD and other SUD prevention, treatment, and recovery services including medication. The experiential clinical training will be delivered pursuant to the NOFO, specifically, the Geisinger Addiction Medicine Fellowship will provide in training tracks that provide a virtual training track that includes an in-person rotation at a teaching health center or in a community-based setting followed by a virtual rotation whereby the fellow will utilize telehealth to continue to support patient care. Additionally, the Geisinger Addiction Medicine Fellowship will provide in person training tracks that include rotations for fellows in community-based settings and in community -based settings that specialize in the treatment of children, adolescents and pregnant and postpartum women. The Geisinger Addiction Medicine Fellowship total funding request for year 1 is $594,802 with a five-year total of $2,969,996.
