Official title
DOT Diary Longitudinal Pilot: A Mobile App for Pre-Exposure Prophylaxis Adherence in Young Men
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The researchers are working with a technology company, AiCure, to develop a smartphone app, DOT Diary, which combines two drug adherence strategies. DOT Diary reminds people when it is time to take their medication, and uses motion-sensing technology to visually and automatically confirm the pill was swallowed. The goal of this study is to assess the impact of the app on adherence to HIV pre-exposure prophylaxis (PrEP) for the prevention of HIV.
