Study Purpose

The purpose of this study was to evaluate the efficacy of an integrated "Retention Clinic" in achieving virologic suppression among HIV-infected cocaine users.

Study Design

This study was a two-group randomized, prospective trial. HIV-infected individuals who report having used cocaine in the 3 months prior to enrollment were eligible. Consented participants were randomized to one of the following two groups: 1) "Retention Clinic" or 2) Treatment as Usual. All participants were provided informed consent and completed a baseline audio computer-assisted self-interview or ACASI focusing on drug use, mental health, demographics and socio-economic factors, HIV care, and drug treatment history as well as blood draws for viral load and CD4 count, and urine collection for toxicology screening. The "Retention Clinic" group received up to 11 Patient Navigator sessions over a 6-month period and 9 sessions of substance abuse treatment over a 3-month period. Follow-up assessments consisted of both ACASI and specimen collection (blood and urine) in all groups were conducted at 6 and 12 months post-randomization. Medical records were reviewed to document use of HIV care, drug treatment, and mental health services during the study period.

Sample

Study participants were recruited from neighborhoods with high rates of HIV and substance abuse, referred to the study teams from community agencies, clinics/medical facilities and treatment programs/centers, and recruited from local hospitals/clinics.

Randomization was stratified at each site by gender equally between intervention and TAU conditions. To obtain the randomization assignment, a member of the site staff called the central Data Manager or Project Manager/Coordinator at their respective sites.

Response Rates

A total of 360 HIV-infected individuals who report cocaine use were randomized, with approximately 180 from each site (Miami, FL and Atlanta, GA), into either the intervention ("Retention Clinic") or Treatment As Usual group, and followed-up at 6 and 12 months post randomization to measure CD4 and viral load counts and other data.
