This study, "Linking Infectious and Narcology Care - Part II (LINC-II)," will implement and
evaluate a multi-faceted intervention (LINC-II), via a two-armed randomized controlled trial
among 240 HIV-infected PWID in St. Petersburg. LINC-II, comprised of pharmacological therapy
(i.e., rapid access to ART and receipt of naltrexone for opioid use disorder) and 12 months
of strengths-based case management, will assess HIV outcomes (e.g., HIV viral load
suppression), impact on care systems and cost-effectiveness of the intervention.
