Brief Summary
This is a prospective, pilot study of HIV-positive individuals who have been on tenofovir-containing antiretroviral therapy for at least 4 months. The overall goal of this research is to determine the feasibility of giving patients and their providers monthly feedback about Tenofovir-Diphosphate (TFV-DP) drug levels and to examine patient and provider behaviors in response to receiving this information. This study will build upon the Aim 1 observational study and the subsequent patient and providerFeedback Development Workgroups (FDWs).

Outcome Measures
Primary Outcomes (3)
TFV-diphosphate (TFV-DP) Drug Level
Tenofovir diphosphate (TFV-DP) in dried blood spots (DBS) is used as a biomarker of antiretroviral therapy (ART) adherence. Recent treatment studies have shown that TFV-DP predicts future viremia in persons with HIV (PWH). Whole blood for DBS was collected at each study visit by venipuncture. To prepare the DBS, 25 mcl of whole blood were spotted five times onto a Whatman 903 ProteinSaver card and dried for a minimum of 3hrs and up to overnight before being individually packaged in a plastic bag with dessicant and a humidity indicator.

Study Arms (1)
Receiving Feedback From DBS
EXPERIMENTALThis arm of participants will receive monthly feedback from medical providers on their adherence measured through DBS.
Interventions
The study team will examine the feasibility and acceptability of a feedback system based on DBS concentration amounts.
