BackgroundPeople with human immunodeficiency virus (PWH) on antiretroviral therapy (ART) with viral load (VL) suppression eliminate the risk of sexual transmission. Many factors including decreased ART adherence and/or medication access barriers decrease the success of treatment as an HIV prevention strategy. ART access may be enhanced with specialty pharmacy services, but the impact compared to community-based practices is variably reported. ObjectivesCompare the impact of specialty vs community pharmacies on medication adherence via VL assessment. MethodsThis retrospective cohort medical record study investigated whether the use of specialty pharmacies compared to community-based practices significantly improves VL suppression. Patients included were enrolled in the Ryan White HIV/AIDS Program (May 31, 2022-May 30, 2023) at an HIV/Infectious Diseases academic medical center clinic. An undetectable VL was defined as the most recent HIV VL being <50 copies/mL or suppressed as <200 copies/mL. Demographic data collected included age range, race, ethnicity and patient reported gender identity. Pharmacy type was determined via review of prescription refill history linked to the medical record. Results1631 PWH were eligible,179 were excluded and 1452 were included in the analysis. 91.3% were virologically suppressed (N=1326) with an undetectable VL in 83.3% (N=1210). When adjusting for age, self-reported gender identity, race, and ethnicity, PWH using specialty pharmacy services were more likely to have a suppressed (AOR 1.469 95% CI 1.007-2.142) and undetectable VL (AOR 1.396, 95% CI 1.051-1.854), respectively, compared to the use of community-based practices. ConclusionsThe use of specialty compared to community-based pharmacies had a significant, yet modest association with VL suppression in PWH enrolled in Ryan White HIV/AIDS services in this single-academic medical center retrospective analysis. Further studies are needed to determine if mail order services, specifically, without specialty service support, are sufficient for high rates of virologic control.
