Linking Infectious and Narcology Care-Part II

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
Russia and Eastern Europe continue to have one of the fastest growing HIV epidemics in the world, with highest transmission risks among people who inject drugs (PWID) and their sexual partners. While routine HIV testing within addiction treatment systems in Russia (i.e., narcology hospitals) is the norm, links between the narcology and HIV care systems are limited and ineffective. In St. Petersburg 50-60% of PWID are HIV-infected, yet among this population less than 10% are on antiretroviral therapy (ART). For Russia to make progress toward the UNAIDS 90-90-90 targets (i.e., 90% aware of HIV diagnosis, 90% of those diagnosed on ART and 90% of those on ART with suppressed HIV viral load [HVL]), a bold new strategy is required. The objective of this study, Linking Infectious and Narcology Care - Part II (LINC-II), is to implement and evaluate, via a two-armed randomized controlled trial among 240 HIV-infected PWID, a multi-faceted intervention combining pharmacological therapy (i.e., rapid access to ART and receipt of naltrexone for opioid use disorder) and 12 months of strengths-based case management. The central hypothesis is that LINC-II will lead to marked progress toward the achievement of the 90-90-90 HIV cascade of care targets among HIV-infected PWID, relative to current standard of care, and that LINC-II will facilitate health system coordination of narcology and HIV care. LINC-II aims to: 1) evaluate the effectiveness of LINC-II on undetectable HVL at 12 months (primary outcome), initiation of ART within 28 days of randomization, change in CD4 count from baseline to 12 months, retention in HIV care (i.e., ≥ 1 visit to medical care in 2 consecutive 6 month periods), and undetectable HVL at 6 months; 2) evaluate the impact of LINC-II on coordinated care across the narcology and HIV health care systems, using mixed methods data from health care providers, administrators, and patients; and 3) evaluate the cost-effectiveness of the intervention to inform policy makers on scaling up the LINC-II approach both within Russia and other countries with HIV epidemics driven by injection drug use.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: LINC-II<br>LINC-II is a multi-faceted intervention combining pharmacological therapy (i.e., ART and naltrexone for opioid use disorder) and 12 months of strengths-based case management delivered to coordinate care across the narcology and HIV health care systems. | Other: Rapid ART initiation<br>* The infectionist will streamline the approval with the ultimate goal of starting participants on ART while they are still hospitalized at the City Addiction Hospital.<br>Drug: Pharmacotherapy for opioid use disorder<br>* Thirteen months of naltrexone treatment for opioid use disorder (injection at baseline, followed by 4 implants).<br>* Other names: Naltrexone;Behavioral: Strengths-based HIV case management<br>* Strengths-based case management: 10 sessions over 12 months in which a trained case manager (CM) meets individually with patients to motivate them to engage in HIV medical care by supporting the recognition of their own strengths to make positive changes in their lives and ultimately improve their HIV outcomes.<br>|
| No Intervention: Standard of Care<br>Participants randomized to the control group will receive the narcology hospital's standard of care, which is detoxification with or without stabilization. Prior to discharge, those identified as HIV-infected are given contact details for an HIV clinic, not an appointment. Upon discharge, patients are encouraged to receive outpatient narcology treatment, monthly, for 1 year. For this study, with regard to linkage to HIV medical care, patients will be given printed information about where to obtain HIV medical care and a resource card containing harm reduction information. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Undetectable HIV Viral Load at 12 Months | Number of participants with undetectable HIV viral load at 12 months, assessed by HIV viral load lab test (<40 copies per milliliter) | 12 months post randomization | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Initiation of Antiretroviral Therapy (ART) | Number of participants who initiated ART within 28 days of randomization. Data will be extracted from medical record. | Within 28 days of randomization | 
| Change in Mean CD4 Count From Baseline to 12 Months | The change in the mean CD4 count (CD4 cells per cubic millimeter) will be calculated from the baseline and 12 months lab results | Change from baseline to 12 months | 
| Retention in HIV Care | Number of participants who had at least 1 visit to HIV medical care in 2 consecutive 6 month periods. Data will be extracted from medical record. | 12 months | 
| Undetectable HIV Viral Load at 6 Months | Number of participants with undetectable HIV viral load at 6 months, assessed by HIV viral load lab test (<40 copies per milliliter). | 6 months |
