Brief summary
Although poor antiretroviral (ART) adherence in HIV does not mean a complete lack of therapeutic results, the benefit of ART increases as adherence improves. Consequences of suboptimal ART adherence are viral rebound, development of drug-resistant HIV strains, and more rapid progression to AIDS. Moreover, HIV-infected persons tend to have numerous co-occurring conditions and therefore take many medications making adherence to multiple drug regimens more difficult. A mobile application capable of improving medication adherence among HIV-infected persons would be highly useful. The investigators propose an intervention study designed to address these potential mechanisms of nonadherence by utilizing the Care4Today v2.0 smartphone application (app). The current study is a small pilot Randomized Controlled Trial (RCT) comparing the smart phone application titled Care4Today v2.0 versus standard of care to improve medication adherence to ART over a 4-week period with 60 HIV-infected participants. The pilot RCT consists of 60 HIV-infected persons who are at risk for ART medication nonadherence. Using random assignment, 30 HIV-infected participants will be assigned to medication adherence improvement via Care4Today app as compared to 30 HIV-infected participants assigned standard of care. The investigators will assess the effectiveness and acceptability of the app in improving objectively measured ART adherence (i.e., via medication event monitoring system caps) over a 4-week period via a pilot RCT with 30 HIV-infected persons assigned to the Care4Today intervention and 30 HIV-infected persons assigned to standard of care.
Interventions
Care4Today mobile application will send automated medication alert messages to HIV-infected persons. The alert messages are customizable and automated, and real-time results are viewable within the application. The Care4Today intervention is designed to improve adherence to ART medications among HIV-infected persons who experience adherence difficulties over standard of care.

Pre-assignment details
We enrolled 60 participants for the study cohort. 58 participants completed the initial assessment, 2 decided to discontinue after randomization (both did not wish to use the mobile application and phone for the duration of the study). Additionally, 1 participant decided to no longer participate in research studies between visits one and two.
