FRI is pleased to announce that Drs. Michael S. Gordon (MPI) and Thomas R. Blue (Co-I), along with Dr. Lauren Brinkley-Rubinstein (MPI, Contact) Associate Professor in the Department of Population Health Sciences at Duke University and Dr. Curt Beckwith (MPI) from The Miriam Hospital/Rhode Island Hospital and Alpert Medical School at Brown University have received a supplement award entitled, “Evaluating the use of long-acting antiretroviral treatment for HIV during community re-entry: Addressing community and structural barriers.” The objective of this study is to use implementation science and partnership with the community to optimize future intervention efforts. Aim 1: To identify how to optimize future long-acting injectable antiretroviral therapy (LAI ART) interventions: Using individual interviews, we will engage a broad range of community stakeholders and service providers from three Ending the HIV Epidemic in the U.S (EHE) geographic areas to investigate the optimal use of LAI ART with incarcerated populations and, importantly, how best to integrate other needed services during community re-entry, including mental health, substance use, and other support services. We will conduct 15 individual interviews with stakeholders (Montgomery County, Maryland Department of Correction and Rehabilitation, Prince George’s County Maryland Department of Corrections, Washington D.C. Department of Corrections) at each site. Aim 2: To co-produce best practice guidelines for future LAI ART interventions: Building on Aim 1, we will convene a series of three focus groups with persons (N = 10) with lived experiences including HIV treatment and incarceration to a) engage in co-analysis of interview data from Aim 1; and b) develop best practice guidelines for future LAI use in carceral and formerly incarcerated populations which will inform a future R01 clinical trial application to be deployed in the identified EHE geographic areas.
