Text Messaging Intervention to Improve HIV Adherence in Rural Drug Users

Completed · Not applicable

Conditions studied: HIV Infections

In brief

The investigators will develop and test the feasibility and promise of a combined HIV adherence assessment and intervention application for rural drug users using an available, familiar technology whose reach will grow exponentially: text messaging via mobile phones. By 2007, 84% of U.S. residents had mobile phones, with near 100% mobile phone penetration projected by 2013. While technology adoption is often slower in under-served communities, the trend is different with mobile phone technology. African-Americans are using more mobile phone minutes per capita and increasing their use at a higher rate compared with other ethnic groups. This technology has great potential to reduce health disparities. In this project, the investigators will develop and test the feasibility and promise of a text messaging application and system using Ecological Momentary Assessment methods to detect nonadherence and drug use and immediately intervene to improve HIV treatment adherence in drug users living with HIV/AIDS who reside outside major metropolitan areas. This R34 is a Stage 1b/2a project in the Stage Model of Behavioral Therapy Development that will develop novel interventions and methods, and generate preliminary estimates of effect sizes that will determine whether a larger clinical trial with extended follow-up and cost-effectiveness evaluation is warranted. The specific aims of this project are: 1. To identify assessment and intervention features relevant to the adherence barriers and drug use patterns of rural and non-urban HIV+ drug users using formative methods including: * structured interviews and focus groups to identify specific barriers to adherence and engagement in care and needs related to drug craving and drug use that should be addressed by the intervention * iterative usability testing of components and drafts of the intervention 2. To create a text messaging mobile phone application and system (Treatment Extension by Texting, Text) to assess and improve HIV treatment adherence and drug use in real time --Text will be built upon a piloted unidirectional personalized text phone application and system, STeM, and will include pre- and post-programming usability testing 3. To test the feasibility and promise of the assessment and intervention tool in a randomized pilot trial of rural HIV+ drug users with detectable viral load (VL) comparing Text to usual care * Feasibility: Identify recruitment rates, consent rates, participant flow, completion rates, and variance of key covariates and outcome variables * Promise: determine point estimates and the precision of effects for primary and secondary adherence outcomes including pharmacy refills and unannounced pill counts (medication adherence), missed visit percentage (treatment engagement), VL, and drug craving and drug use.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 18 or older
• has a detectable viral load
• reports use of at least one illicit drug in last 30 days
• requires ART
• able to receive mobile phone service at home address

You may not qualify if…

• lack of English proficiency
• planning to move out of area in the next six months
• inability to provide consent.
• Note regarding "inability to provide consent": Traditionally, some patients with HIV whom we evaluate for potential participation in research studies are not able to provide informed consent, either due to significant cognitive decline, or their designation of someone else as their legal proxy. When this occurs, we do not offer them study participation because legally, they are unable to consent, even if currently, their cognitive capacities seem intact. We have generally assessed this through a series of branching questions to determine their legal and cognitive capacity for consent.
