High Provider Trust Associates with High HIV Antiretroviral Adherence among Women Living with HIV in a Metropolitan Washington, DC Cohort

Trust in providers and health care systems (HCSs) has been associated with higher HIV antiretroviral (ART) adherence; however, most previous studies enrolled primarily men and did not concurrently assess provider trust, HCS distrust, and clinical/biological outcomes. We enrolled 239 Washington, DC Women's Interagency HIV Study (WIHS) women: 167 with HIV (WWH) and 72 without HIV. In 2006 and 2017-2018, women completed surveys on provider trust and HCS distrust. Clinical, social, and demographic covariates were obtained during the 2017-2018 WIHS study visit. Descriptive analyses included chi-squared and Mann-Whitney tests. Wilcoxon signed-rank tests assessed trust measure change over time. Logistic (provider trust) and linear (HCS distrust) models were constructed in R. The majority of women were African American/black (76.9%) with a median age of 52 (interquartile range 48, 58) and currently insured (99.6%). In multi-variable analyses, women with HIV (WWH) had higher odds of high provider trust (adjusted odds ratio [aOR] 2.90, 95% confidence interval [CI] 1.34, 6.45), with >= 95% ART adherence associated with high provider trust among only WWH (aOR 4.13, 95% CI 1.14, 15.92). Multi-variable models also showed 3.40-point higher HCS distrust scores among WWH who reported >= 95% ART adherence (p = 0.03). CD4 count and HIV viral load were not associated with provider trust or HCS distrust. Provider (p = 0.67) and HCS (p = 0.65) trust did not significantly change in this population at two time points for 10 years. Self-reported antiretroviral therapy adherence significantly associated with high provider trust, yet also with high HCS distrust, revealing a nuanced relationship to providers and the HCS among WWH.
