Linkage and Retention: A Randomized Trial to Optimize HIV/TB Care in South Africa

The purpose of this study is to test the effects of a health system navigator intervention on rates of linkage to human immunodeficiency virus (HIV) and tuberculosis (TB) care among newly diagnosed HIV-infected outpatients in Durban, South Africa. Subjects will be approached in the outpatient department and enrolled prior to an HIV test. Subjects will then be randomized to the navigator arm or the standard of care arm. Subjects in the navigator arm will receive scheduled phone and short message service (SMS) contacts throughout the follow-up period to help guide them through the HIV and TB care pathways. The navigator will provide personalized support to help subjects overcome barriers they may face along the way.

About this study

This project is a randomized controlled trial of an intervention to improve linkage to HIV and TB care for South Africans undergoing HIV testing. Subjects undergoing HIV testing will be enrolled at three sites in the greater Durban area. These sites comprise two hospital-affiliated outpatient departments and primary health clinics served by a mobile health van. Routine TB screening, regardless of signs or symptoms, will be offered to all HIV-infected participants. HIV-infected participants will be randomized to determine whether they will be assigned to a health system navigator or will receive the current standard of care in Durban. Block randomization will be stratified by site and gender, with blocks of varying length.

The health system navigator will help patients identify barriers to entering care and devise solutions, optimize use of available resources, and serve as a trusted social supporter who is knowledgeable about the health care system but remains outside of it. The health system navigator will help subjects engage the HIV and TB care system through face-to-face contact, telephone conversations, and short messaging service SMS text reminders which are free for patients to receive. These phone contacts and SMS will follow a standardized protocol. We will evaluate the efficacy of the intervention, as measured by increased rates of antiretroviral therapy (ART) initiation and, for those with TB co-infection, TB treatment completion. We will also evaluate the cost and cost-effectiveness of this intervention.

Treatment and study plan

Health System Navigator

Behavioral

Subjects will be enrolled prior to an HIV test. Following TB screening, HIV infected subjects will meet with the health systems navigator who will administer a brief strengths-based interview. During this interview the participant and navigator will identify barriers to HIV and/or TB care and the resources and strengths that will be most helpful in overcoming these barriers. The health system navigator will stay in contact with participants for the next 4 months using phone calls and SMS on a standardized schedule. During the phone contacts the health system navigator will assess where the participant is on the care pathway. If the participant has not completed a step in his/her HIV or TB care, the health system navigator will help the participant draw on strengths identified in the initial interview and overcome any obstacles hindering him/her from accessing care.

Primary outcomes

  1. Linkage and Retention in Care: ART-eligible Patients

    Time frame: 9 Months after Enrollment

    For ART-eligible HIV-infected patients, 3 months on ART as documented by ART initiation date in the electronic medical record.

  2. Linkage and Retention in Care: TB Patients

    Time frame: 9 Months after Enrollment

    For patients co-infected with TB, 6 months of TB treatment as documented by a written discharge of treatment outcome from a TB clinic.

  3. Linkage and Retention in Care: ART-eligible HIV/TB Co-infected Patients

    Time frame: 9 Months after Enrollment

    For HIV and TB co-infected patients who are ART-eligible, completion of either the ART or TB treatment outcome will be considered successful completion of the Primary Outcome Measure.
