Positive Health Check (PHC) is a tailored video counseling intervention developed by RTI International and the Centers for Disease Control and Prevention (CDC). This video aims to address the urgent challenge in the United States of decreasing HIV transmission risk by increasing antiretroviral therapy (ART) adherence and retention in HIV primary care for people living with HIV (PLWH). PHC uses best practices in tailored communication, social, and behavioral science theory for motivating HIV-related behavior change and digital communication strategies to deliver highly relevant and engaging messages to PLWH. Users of all genders select tips and questions for their provider, and PHC automatically generates printed handouts that users can bring to their appointment. The Extra Info section provides additional information on a range of HIV prevention topics, wellness, and healthy lifestyles. The project aims to: 1) test the impact of PHC on achieving better clinical outcomes (i.e., viral load suppression, ART prescription refills, clinic appointment attendance) and reducing HIV risk, 2) examine PHC implementation longitudinally to assess change over time in the perceived “fit” of PHC, the context for PHC implementation, the feasibility of PHC implementation, and patient-provider communication, 3) document costs associated with PHC implementation, and (4) describe the standards of care used in each clinic that are related to risk reduction, adherence, and retention in care.
