Brief summary
The overall goal of this study is to design a user-centered design app linked to a smart pill box for people living with HIV (PLWH) and evaluate its effects in a randomized controlled trial. The proposed trial is scientifically significant in representing a principled and systematic effort to test the efficacy of a smartphone intervention linked to a smart pill box for antiretroviral (ART) adherence in PLWH in the United States (US). Guided by a strong theoretical framework building on earlier user-centered design work and integrating a real-time monitoring device, this work has the potential to improve ART adherence in PLWH and have a sustainable public health impact.
Detailed description
Human Immunodeficiency virus (HIV) continues to affect 1.2 million Americans. Achieving viral suppression through adherence to antiretroviral (ART) therapy is a critical determinant of successful transmission prevention and long-term outcomes in HIV-infected patients. However only about 25% of persons living with HIV (PLWH) in the US are virally suppressed, demonstrating the need for effective interventions that enhance ART adherence. mHealth is a tool that has proven useful in supporting behavior change, but most mHealth tools for PLWH have not been well-developed or evaluated. Given the dearth of useful and likeable apps, the need for improving medication adherence in PLWH, and the great promise of mHealth, the investigators propose to build and test a user-centered smartphone app linked to a smart pill box targeting ART adherence in PLWH. Self-report of medication adherence is often criticized since it typically overestimated adherence especially in unmasked trials. Current adherence assessments, such as patient recall, pill counts and pharmacy refill data, typically detect missed doses long after they occur. This study will use real-time, wireless monitoring strategies via the Wisepill dispenser, for measuring ART adherence.

| Change in Score on the Center for Adherence Support Evaluation (CASE) Index | Baseline, 3 month follow up, and 6 month follow up | The CASE Adherence Index is an easy to administer instrument that provides an alternative method for assessing ART adherence in clinical settings. Items are scored such that higher values indicate better adherence, minimum score is 3 and the maximum total score is 16. Scores of 11 or higher on this index indicate good adherence (Cronbach's α= 0.79). |
| Change in Score on the Engagement With Health Care Provider Scale | Baseline, 3 months, and 6 months | The Engagement with Health Care Provider 13-item Scale will be administered over the course of the trial to evaluate how participants' engagement with their health care providers changes their health care access overall.
