Not Applicable

Completed

Conditions: HIV

Interventions: Behavioral: SMS text message
Behavioral: SMS text message + Peer Navigation

Registration Number: NCT02417233

Lead Sponsor: University of California, San Francisco

Brief Summary: This study will evaluate the efficacy of two strategies for enhancing overall preventive behaviors, retention in HIV care, and adherence to medication for HIV positive individuals in South Africa: short message service (SMS) text messaging and peer navigation services.

Detailed Description: Treatment-as-prevention represents a game changing potential to stem further HIV transmission by ensuring that infected individuals are tested, linked to care, retained in care, and adherent to their regimens. Little is known, however, about the most feasible and cost-effective means to promote overall engagement in care coupled with behavioral risk reduction for HIV positive individuals in South Africa. For this reason, the study proposes to first assess what engagement in care activities are underway in select clinics in the Bojanala Platinum District, North West Province, South Africa, and will then implement and evaluate the feasibility, acceptability, and potential efficacy of two strategies for enhancing overall preventive behaviors, retention in HIV care and adherence to medication. The first strategy will employ automated text message reminders to encourage patients to return for needed care, adhere to their antiretroviral therapy (ART) regimens, and practice safer sex and other risk reduction behaviors. This approach also includes designation of a retention, adherence, and prevention monitor to supervise the system. A second strategy builds on the first model, including the automated text message system, but also utilizes peer navigator-provider teams to serve as point people for care engagement. Peer navigators will work with providers to introduce patients to care and help them establish a care and prevention plan. They will also check in with patients to discuss and support resolution of challenges to engaging in care, adhering to drug regimens, and reducing transmission risk behavior.

Arm && Interventions

Group	Intervention	Description
SMS text message	SMS text message	Participants are administered baseline, 6 month, and 12 month questionnaires and provided with the study incentive (mobile phone airtime). In addition, they receive automated bi-weekly behavioral text messages aimed at improving health and reducing transmission risk and also automated bi-weekly "check-in" text messages that will trigger a phone call from clinic staff if the participant reports not being well.
SMS text message + Peer Navigation	SMS text message + Peer Navigation	Participants are administered baseline, 6 month, and 12 month questionnaires and provided with the study incentive (mobile phone airtime). In addition, they receive automated bi-weekly behavioral text messages aimed at improving health and reducing transmission risk and also bi-weekly contact from an HIV-positive peer who provides personalized support and with health or other service systems navigation assistance.

Primary Outcome Measures

Name	Time	Method
Retention in Care - ART Eligible (Participants Eligible for ART Who Initiated ART and Who Remain on Treatment)	12 months	Participants eligible for ART who initiated ART and who remain on treatment 12 months from enrollment. Retention in care at 12 months is defined as at least 4 clinical care visits with less than 4 months between each visit.
Adherence to ART - Objective (Viral Load Test Results <400 Copies/mL)	12 months	Viral load test results \<400 copies/mL (consistent with current and correct adherence to ART)
Adherence to ART - Subjective (Self-reported Ability to Take ART as Prescribed in Last Month)	12 months	Self-reported ability to take ART as prescribed in last month, assessed at 12 months from enrollment. Considered compliant if reported "very good" or "excellent" adherence.
Timely Antiretroviral Therapy (ART) Initiation (Participants Eligible for ART Who Initiate Treatment Within 3 Months of Diagnosis)	3 months	Participants eligible for ART who initiate treatment within 3 months of diagnosis
Retention in Care - Non-ART (Participants Who Return for Repeat CD4 Testing Within 12 Months of Diagnosis)	12 months	Participants who return for repeat CD4 testing within 12 months of diagnosis
Linkage to Care - Participants Who Received Cluster of Differentiation 4 (CD4) T-cell Count Test Result Within 3 Months of Testing HIV-positive (Binary)	3 months	Participants who received CD4 count test result within 3 months of testing HIV-positive (binary)
