While improvements in HIV care have been made, some people living with HIV still struggle with their HIV treatments. Results from the Positive Perspectives study highlighted barriers to adherence, and authors noted these may be addressed through increased treatment choices, particularly options that are simplified or less conspicuous parts of the lives of people living with HIV could help improve self-reported health outcomes.1 Published data from Positive Perspectives show that some people living with HIV still struggle with their daily oral antiretroviral therapy (ART). For this group, the result of this struggle may be suboptimal adherence*, or not conforming with the healthcare provider’s (HCP) recommendations for medication dosage and frequency.1 Suboptimal adherence in HIV is known to impact disease progression, transmission and the development of treatment resistance.2,3,4

Nearly 1 in 4 (24%, n=575/2389) people living with HIV in the Positive Perspectives study reported suboptimal adherence.1

  • Those who reported emotional or psychosocial challenges with daily oral therapy, including fear of unwanted sharing of their HIV status, had higher odds of reported suboptimal adherence to daily oral ART
  • Those study participants who reported being told that Undetectable = Untransmittable (U=U) by their HCPs had lower odds of reported suboptimal adherence than those who reported not being told about U=U by their HCPs
  • Groups within the study who reported poorer adherence than other study participants included those who reported polypharmacy (defined in the study as taking five or more pills per day or medications for five or more health conditions), those reporting experiencing gastrointestinal side effects from their medicines and, those who reported not being informed about the benefits of adherence by their HCPs

Looking into the reasons for suboptimal adherence reported by people living with HIV in the Positive Perspectives study, feelings of depression/being overwhelmed (7%, n=176/2389), a desire to forget about having HIV (7%, n=168/2389), and work (6%, n=145/2389) were the top reported reasons for missing daily oral ART for ≥5 times per month. Those study participants who reported multiple reasons for missing daily oral ART had higher odds of self-reported virologic non-suppression.1

“Even those people living with HIV who have access to treatment still have challenges that need to be addressed. Open dialogue with healthcare providers about emotional and practical challenges can support quality of life and health outcomes.”

The Positive Perspectives study authors suggest that a possible strategy for reducing treatment challenges for those who are struggling with suboptimal adherence may be offering treatments that reduce the need for daily dosing: “Simplifying HIV regimens so they are a less conscious or conspicuous part of patients' lives … may improve adherence and health outcomes.” 1

The Positive Perspectives study is one of the largest, global, HIV patient-reported outcomes (PROs) studies to date, with 2,389 people living with HIV participating from 25 countries. Participants were asked to rate their own health, how living with HIV impacts their lives and affects their outlook for the future, as well as examining their interactions and relationships with HCPs and their experiences with ART. All findings are self-reported.

*In the Positive Perspectives study, suboptimal adherence was defined as a report of ≥1 reason for missing ART ≥5 times within the past month.

Global Positive Perspectives data demonstrate a strong link between high reported engagement with healthcare providers (HCPs) and positive self-reported health outcomes for people living with HIV (PLHIV), yet study results also show many do not feel comfortable raising important treatment issues.

The latest Positive Perspectives (Wave 2) is one of the largest, global, HIV patient-reported outcomes (PROs) studies to date and provides perspectives from a diverse group of people living with HIV across the world.
