Infectious Disease (ID) Testing OUtreach in Carceral Hubs

This pilot feasibility study represents part 3 of a larger R61 study, where the investigators will follow a cohort about their experiences with human immunodeficiency virus (HIV) testing. This project aims to assess the effectiveness of an intervention at two jail sites in the Boston area: South Bay House of Corrections and Nashua Street Jail implemented in January of 2025 that is aimed at improving HIV testing practices and HIV treatment in those carceral facilities. This implementation was developed independently of the investigators' study activities. The jails worked to develop changes in their electronic health record to offer HIV testing at various points in their intake and physical exam process. HIV care was not well-integrated with the jails' existing intake and healthcare administration systems and medications for opioid use disorder (MOUD) program. The investigators will evaluate the intervention the jails developed to address these issues. The outcomes of interest are more implementation than effectiveness outcomes. The primary goal of this study is to identify existing barriers in the carceral healthcare setting that prevent the improvement of HIV testing and treatment.
