SteadyRx: Smartphone ART Adherence Intervention for Drug Users
In Brief
A clinical study evaluating SteadyRx for HIV and Medication Adherence. Completed, enrolled 51 participants across 1 site.
Detailed Summary
Antiretroviral therapy (ART) increases life expectancy and quality of life for individuals infected with HIV, and can reduce the chance of HIV transmission, but a high degree of adherence to ART is required to achieve these benefits. Unfortunately, only 59% of patients in North America report ART adherence \>90%. Thus, ART adherence interventions are a critical part of the fight against HIV/AIDS. Injection drug use and crack cocaine use are major factors in the transmission of HIV, and are associated with non-adherence to ART. Several types of interventions, most notably directly administered antiretroviral therapy (direct observation of antiretroviral administration and patient supports) and contingency management (the provision of incentives contingent upon objective evidence of adherence) have been effective in promoting ART adherence in drug users. However, a core problem with all ART adherence interventions is that their effects do not last after the interventions are discontinued. The common finding of post-intervention dissipation of effects suggests that ART adherence interventions may need to be long-term or even permanent adjuncts to ART for drug users. The investigators intend to develop an intensive intervention that incorporates the most effective techniques for promoting ART adherence in drug users, and delivers them in a manner that allows for their large-scale implementation as long-term or even permanent adjuncts to ART. Thus, we will bundle a targeted group of effective component interventions into a smartphone application that is easy for patients to use, simple to manage, and maximally convenient for all stakeholders. Our ultimate goal is to produce an intervention that is highly effective and scalable. Toward that end, the SteadyRX intervention to be developed under this project will be largely automated and will (1) facilitate consultation with care providers (2) provide reminders when a dose is overdue, (3) provide electronic remote observation of medication-taking, and (4) reward ART adherence. In addition to developing this smartphone-based intervention, a pilot study will be conducted in 50 HIV+ adults with a history of problem drug use. In this study, participants will be randomly assigned to receive usual care, or usual care plus the SteadyRX intervention.

Timeline
Interventions
The proposed intervention consists of four core elements. The intervention will include a Smartphone application that allows direct interaction with the SteadyRx system, as well as automatic events controlled via a central server. The CONSULT element will facilitate patient-provider communication with links to care providers and other care resources. The REMIND element will provide telephonic reminders for late doses. The OBSERVE element will feature electronically observed dosing through time-stamped video recordings made on the Smartphone and sent securely to a central server. The REWARD element will feature monetary incentives designed to reinforce short- and long-term medication adherence and promote reductions in viral load.
