Patient-reported outcomes in HIV clinical trials evaluating antiretroviral treatment: a systematic review

Abstract

ABSTRACT We aimed to assess patterns of patient-reported outcomes (PRO) instruments’ utilization in HIV clinical trials in relation to antiretroviral therapy (ART). PubMed/MEDLINE, Scopus, and EMBASE were searched using the terms “Patient-Reported Outcomes” and “HIV/AIDS” or “Antiretroviral Treatment” or “ART” or “Antiretroviral Therapy” from 1 January 1990 until 1 December 2019. In total, 173 studies were identified and 26 were directly related to ART. Study population included treatment-naïve patients (n = 4), treatment-experienced (n = 20), or both (n = 2). Instruments were implemented to assess general experience with ART (n = 3), single-tablet regimens (STR) (n = 2), monotherapy (n = 4), regimen switch (n = 9), or regimen comparison (n = 8). The most commonly used instruments were Medical Outcomes Study-HIV Health Survey (MOS–HIV, n = 8), HIV Symptom Index (HIV-SI, n = 7) and unstructured self-reports (n = 5) followed by others. MOS–HIV was used mainly in comparative (n = 4) and monotherapy (n = 3) trials, HIV-SI in switch (n = 4) and STR (n = 2) trials, and self-reports in comparative trials (n = 3). Even though, the implementation of PRO tools is increasing with time, reporting of PRO in HIV clinical trials remains limited.
