Medication adherence feedback intervention predicts improved human immunodeficiency virus clinical markers

Thirty‐three participants in a human immunodeficiency virus ( HIV ) medication adherence feedback ( MAF ) intervention were compared with 58 HIV ‐positive non‐participants in laboratory‐tested CD 4 and viral load. The intervention provided adherence feedback and counselling based on a visual display from an electronic pill bottle ( MEMS TM ). Multiple regression controlling for baseline CD 4 and showed that postintervention CD 4 was higher for MAF participants than for non‐ MAF participants. Non‐ MAF participants' CD 4 significantly declined over time. MAF participants were also less likely than non‐ MAF participants to have a detectable postintervention viral load.
