The National Institute on Alcohol Abuse and Alcoholism (NIAAA) awarded a $602,107 Project Grant under the Alcohol Research Programs (CFDA 93.273) to Harvard Pilgrim Health Care Inc.'s Office of Sponsored Programs Division. The grant supports a study to assess the impact of the National Health Service Corps (NHSC) expansion on disparities in alcohol use disorder (AUD) treatment and outcomes across geographic areas and population groups. The research aims to determine if the substantial growth in the NHSC mental health workforce since 2009 has reduced disparities in AUD mortality, unmet treatment needs, and utilization of alcohol-related emergency and hospital services between mental health professional shortage areas and non-shortage areas. The project will employ quasi-experimental methods using national data sources to generate evidence that can inform policy decisions related to the NHSC and strategies to further reduce AUD treatment disparities. The award period is from May 15, 2024 to April 30, 2028.
