Evaluating Methods to Increase HIV Testing, Access to HIV Care, and HIV Prevention Strategies

March 28, 2025 updated by: HIV Prevention Trials Network

TLC-Plus: A Study to Evaluate the Feasibility of an Enhanced Test, Link to Care, Plus Treat Approach for HIV Prevention in the United States

This is a five-part study that will take place in the Bronx, New York (NY), and Washington, District of Columbia (DC). The different components of the study will focus on increasing the number of people being tested for HIV, evaluating ways to link HIV-infected people to HIV care sites, evaluating methods to reinforce antiretroviral therapy (ART) adherence, and evaluating a counseling program that focuses on HIV prevention. (Details for only three components of this study are included in ClinicalTrials.gov (Linkage-to-Care, Viral Suppression and Prevention for Positives) because they are the only ones that were randomized and had prescriptive interventions.)

Study Overview

Detailed Description

The five components of the study include the following:

Expanded HIV Testing: The purpose of this part of the study is to increase the number of people being tested for HIV. In select study sites in the Bronx, NY, and Washington, D.C., HIV testing will be expanded in emergency departments (EDs) and upon hospital admission. The study will provide additional resources to expand outreach and marketing efforts in these communities. This part of the study will take place over 36 months.

Linkage-to-Care: This part of the study will take place over a 24-month period. The purpose is to compare the effectiveness of a financial incentive (FI) program to link HIV-infected people from HIV test sites to HIV care sites versus standard of care (SOC). Each HIV test site will be randomly assigned to either the FI program or SOC. At the FI sites, people who receive an HIV positive test result will receive a coupon that can be redeemed for gift cards at participating HIV care sites.

Viral Suppression: This part of the study will assess the effectiveness of an FI program at helping HIV-infected people achieve and maintain a viral load of less than 400 copies/mL compared to SOC. Each HIV care site will be randomly assigned to either the FI program or SOC. At the FI sites, HIV-infected people will receive gift cards if their viral load remains below 400 copies/mL. People are eligible to receive FIs once every 3 months throughout the 24-month study period.

Prevention for Positives: The purpose of this component of the study is to evaluate the effectiveness of a computer-delivered counseling program that focuses on HIV risk reduction behaviors for HIV-infected people. Participants will be randomly assigned to the counseling program and SOC or SOC alone. All participants will answer questions on the computer about HIV testing and care at baseline and Months 3, 6, 9, 12, and 18. Study researchers will review participants' medical records at study entry and every 3 months up to Month 18.

Survey of Patients and Providers: Participants in the Prevention for Positives component of the study will complete a computerized survey at the baseline and Month 12 visit, which will assess knowledge and attitudes about ART. Health care providers at the HIV care sites will complete Web-based surveys before and after the Viral Suppression component of the study.

Description

Inclusion/Exclusion Criteria for Linkage-to-Care Component:

The Linkage-to-Care component of the study will include all individuals ages 12 and older who are permitted to consent, or can be consented for HIV care by a parent/legal guardian according to New York State or Washington, D.C. law, and who are newly found to be HIV-positive at HIV test sites participating in the study. This study component will also include individuals who have been previously diagnosed with HIV but have been out of care for at least a year and are reconfirmed for HIV infection by standard laboratory tests

Inclusion/Exclusion Criteria for Viral Suppression Component:

The study population for the viral suppression component of the study will include all individuals ages 12 and older who are permitted to consent, or can be consented for HIV care by a parent/legal guardian according to New York State or Washington, D.C. law, who have initiated care at participating HIV care sites.

Inclusion Criteria for Prevention for Positives Component:

  • All people who are permitted to consent for HIV care according to New York State or Washington, D.C. law
  • Receiving care at the selected HIV care sites in the Bronx or Washington, D.C.
  • Have attended the clinic one or more times in the 7 months before study entry
  • Able to understand either spoken English or Spanish
  • Able and willing to provide informed consent
  • Participants enrolled into the Prevention for Positives component of the study will participate in the Patient Survey Component

Exclusion Criteria for Prevention for Positives Component:

  • Not seen in the clinic in the 7 months before study entry
  • History or evidence of altered mentation, inebriation, or substance use that would interfere with participation in the study
  • Unable or unwilling to provide informed consent
  • Participation in another study focusing on HIV prevention for positives

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Linkage-to-Care Component: Financial Incentive (FI)
Provide financial incentives for linkage to HIV care.
Test sites assigned to this arm will provide coupons to all people who are found to be HIV-infected after testing and who are not already linked to HIV care. The coupons can be redeemed at a participating HIV care site for gift cards.
Active Comparator: Linkage-to-Care Component: Standard of Care (SOC)
Provide the SoC to patients for linkage to HIV care
Each person who receives an HIV positive test result, and is not currently in care, will be directed to HIV care sites using the site's SOC procedures.
Experimental: Viral Suppression Component: FI
Provide financial incentives for viral load suppression
HIV-infected participants who are receiving ART will be offered FIs upon the confirmation of each suppressed viral load measurement (less than 400 copies/mL).
Active Comparator: Viral Suppression Component: SOC
Provide the SoC to patients for viral load suppression
HIV-infected participants who are receiving ART will be offered support via the site's SOC procedures to attend HIV care site visits and remain adherent to their ART regimen in order to achieve and maintain viral load suppression.
Experimental: Prevention for Positives Component: Intervention
Computerized HIV risk reduction counseling program
Participants will complete a computer-delivered counseling program that emphasizes HIV prevention strategies for HIV-infected people.
Active Comparator: Prevention for Positives Component: SOC
Receive SOC for HIV infection
Participants will receive SOC from their HIV care site.
