About this study
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Health System NavigatorBehavioural
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Linkage and Retention in Care: ART-eligible Patients
For ART-eligible HIV-infected patients, 3 months on ART as documented by ART initiation date in the electronic medical record.
Measured: 9 Months after Enrollment
Linkage and Retention in Care: TB Patients
For patients co-infected with TB, 6 months of TB treatment as documented by a written discharge of treatment outcome from a TB clinic.
Measured: 9 Months after Enrollment
Linkage and Retention in Care: ART-eligible HIV/TB Co-infected Patients
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.
Measured: 9 Months after Enrollment

Questions about this trial
What is this clinical trial studying?
A study testing Health System Navigator in people with HIV, run by Massachusetts General Hospital at 4 sites in South Africa.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in South Africa. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Linkage and Retention in Care: ART-eligible Patients (time frame: 9 Months after Enrollment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01188941, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2017.
