2514. Real-time Antiretroviral Electronic Adherence Monitoring In Young African American Men Who Have Sex With Men

BACKGROUND: Antiretroviral therapy adherence remains a challenge, particularly for young African American men who have sex with men (YAAMSM). We enrolled 40 YAAMSM for 3 months of electronic adherence monitoring (EAM). These data may be useful in developing an antiretroviral EAM intervention that responds to missed doses with real-time text messages. METHODS: YAAMSM (age 18–34 years) living with HIV and taking ART participated in a quantitative and qualitative study that included ART adherence monitoring with a Wisepill electronic monitoring device for up to 3 months. Interviews were performed during April 2017–April 2019 at baseline and follow-up. Monitoring data were reviewed to determine timing and patterns of missing their first true adjudicated miss for durations of 1 dose, 3 consecutive days, and 7 consecutive days. Follow-up qualitative interviews included exploring acceptability of monitoring. RESULTS: The median age was 28 years and median participant observation time was 90 days (interquartile range 88–90 days) (n = 40 participants). Among those with at least 2 weeks follow-up and adjudication (n = 32), 100% missed at least 1 day. Most (82%) of these participants were <80% adherent in at least one of their monitored months. One dose and 3-day misses did not cluster (e.g., no disproportion on weekends). Most (88%) first missed doses occurred during the first 9 days monitored and most (69%) of the 13 who missed 3 consecutive days missed within the first monitored month. Four participants missed 7 consecutive days. Among 31 with a follow-up interview, 28 (90%) felt receiving a text because of device monitoring would affect their medication taking in the future. Illustrative quotes included, “It made me more responsible” and “…it makes you want to do it right.” CONCLUSION: Most YAAMSM living with HIV in this study had adherence below the target threshold of >80%. These data support development of a text message responsive real-time electronic adherence monitoring intervention approach. DISCLOSURES: All authors: No reported disclosures.
