Abstract
MTN-017 compared the safety and acceptability of daily oral emtricitabine/tenofovir disoproxil fumarate, daily reduced-glycerin 1% tenofovir gel applied rectally, and the same gel applied before and after receptive anal intercourse. The Data Convergence Interview (DCI) and the Pharmacokinetic Data Convergence Interview (PK-DCI) were brief, collaborative interactions conducted with participants during adherence counseling sessions to improve accurate measurement of adherence to study product use. DCIs converged data from product return counts and participants’ responses to daily text messages. PK-DCIs, conducted 4 weeks later, converged results of the DCI with PK from the corresponding period. CIs were easily incorporated into adherence counseling sessions, increased the accuracy of adherence data, and provided valuable context to data on product use. Participants were readily engaged in the interviews but, if they felt confronted, provided more guarded responses. As such, how these CIs are conducted is critical to engage participants, even those with poor adherence, to openly discuss challenges with product use.
Resumen
En el estudio MTN-017 se comparó la seguridad y la aceptabilidad entre: una dosis oral diaria de emtricitabine/tenofovir disoproxil fumarate; un gel de 1% tenofovir aplicado diariamente por vía rectal; y el mismo gel aplicado antes y después del coito anal receptivo. La Entrevista de Coincidencia de Datos (ECD) y la Entrevista de Coincidencia de Datos Farmacokineticos (ECD-FK) eran breves interacciones colaborativas con los participantes, llevadas a cabo durante las sesiones de consejería de adherencia, para mejorar la medición de adherencia en el uso del producto durante el estudio. Las ECD combinaron datos de los conteos de productos devueltos y las respuestas de los participantes a mensajes de texto diarios. Las ECD-FK, que ocurrieron cuatro semanas después, combinaron los resultados de la ECD con el FK del período correspondiente. Las dos entrevistas de coincidencia fueron incorporadas fácilmente en las sesiones de consejería de adherencia, aumentaron la precisión de los datos de adherencia y agregaron un contexto para interpretar los datos sobre el uso del producto. Fue fácil involucrar a los participantes en las entrevistas; no obstante, si se sentían confrontados, sus respuestas eran más cautelosas Por lo tanto, cómo se llevan a cabo las entrevistas de coincidencia es clave para establecer cooperación con los participantes, aun los que tienen la más baja adherencia, para que compartan abiertamente los desafíos que enfrentan al usar el producto.
