Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, the investigators propose to develop a real-time adherence intervention based on SMS (i.e., text messages), wireless adherence monitoring (with the Wisepill device), and engagement of social support that is tailored to rural sub-Saharan Africa. The investigators will build on research by others who have shown SMS reminders improve adherence and viral suppression in Kenya, albeit with relatively small effect sizes and suboptimal virologic failure rates even in the intervention arm. Moreover, little is known about which patients benefit from SMS, why they benefit, and what can be done to further improve adherence and treatment success rates. Understanding the mechanisms of effect will make it possible to design and test evidence-based interventions with the highest likelihood for efficacy.

In a cohort of HIV-infected individuals starting ART and being monitored with Wisepill, the investigators will test 1) daily SMS reminders, 2) weekly SMS reminders, 3) SMS reminders linked to real-time detection of missed doses, and 4) SMS reminders plus SMS notifications of 48+hour gaps in adherence to members of social support networks. The investigators will conduct qualitative interviews to learn the experiences of participants and members of their social support networks with the different types of SMS. This staged approach will allow us to fully understand and compare the additive effects and acceptability of SMS-based interventions. The investigators will also determine behavioral effect mechanisms, as well as compare the impact of each type of SMS with a control population receiving only Wisepill monitoring on adherence and HIV RNA.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Fixed SMS, real-time monitoring

SMS will be sent daily for one month, then weekly for two months. Participants will have real-time adherence monitoring and social supporters will be notified of gaps in adherence of 48+ hours in the last six months of the study.

Group Type EXPERIMENTAL

Fixed SMS, real-time monitoring

Intervention Type DEVICE

SMS reminders will be sent daily for one month, then weekly for two months, then as needed for missed doses to encourage adherence. The Wisepill system will automatically capture and report each time the device is opened as a proxy for the participant's adherence.

Triggered SMS, real-time monitoring

Participants will have real-time adherence monitoring and social supporters will be notified of gaps in adherence of 48+ hours in the last six months of the study.

Group Type EXPERIMENTAL

Triggered SMS, real-time monitoring

Intervention Type DEVICE

SMS reminders will be sent as needed for missed doses to encourage adherence. The Wisepill system will automatically capture and report each time the device is opened as a proxy for the participant's adherence.
