ABSTRACT
Measurement of adherence to oral pre-exposure prophylaxis (PrEP) in real-time has been challenging. We developed DOT Diary, a smartphone application that combines automated directly observed therapy with a PrEP adherence visualization toolkit, and tested its ability to measure PrEP adherence and to increase adherence among a diverse cohort of young men who have sex with men (MSM). We enrolled 100 MSM in San Francisco and Atlanta and randomly assigned them 21 to DOT Diary versus standard of care. Concordance between DOT Diary measurement and drug levels in dried blood spots was substantial, with 91.0% and 85.3% concordance between DOT Diary and emtricitabine-triphosphate and tenofovir-diphosphate, respectively. There was no significant difference in the proportion of participants with detectable PrEP drug levels at 24 weeks between study arms. These results suggest DOT Diary is substantially better than self-reported measures of adherence, but additional interventions are needed to improve PrEP adherence over time.
RESUMEN
RESUMEN La medición de la adherencia a la profilaxis oral previa a la exposición (PrEP) en tiempo real ha constituido un desafío. Hemos desarrollado DOT Diary, una aplicación para teléfonos inteligentes que combina la terapia automatizada observada de forma directa con un kit de herramientas para visualizar la adherencia a la PrEP, y testeamos su capacidad para medir la adherencia a la PrEP, así como para aumentar la adherencia entre una cohorte variada de hombres jóvenes que tienen sexo con hombres (HSH). Reclutamos a 100 HSH en San Francisco y Atlanta y los asignamos aleatoriamente 21 a DOT Diary con respecto a la asistencia estándar. La concordancia entre la medición del DOT Diary y los niveles de fármacos en gotas de sangre seca fue sustancial, con un 91,0% y un 85,3% de concordancia entre el uso del DOT Diary y el de emtricitabina-trifosfato y tenofovir-difosfato, respectivamente. No hubo diferencias significativas en la proporción de participantes con niveles detectables del fármaco de la PrEP a las 24 semanas entre los brazos del estudio. Estos resultados sugieren que DOT Diary es sustancialmente superior a las medidas de adherencia que se notifican de forma personal, aunque hacen falta intervenciones adicionales para mejorar la adherencia a la PrEP a largo plazo.
