988. Overcoming Prescriber Concerns through Successful Access and Affordability of PrEP

BACKGROUND: Increasing the number of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) providers expands PrEP access to more eligible patients and aids in ending the HIV epidemic. Non-prescribers of PrEP have noted perceived financial barriers as a limitation to prescribing. The purpose of this study is to describe the PrEP medication access process and outcomes in patients seen at a multidisciplinary PrEP clinic. METHODS: We conducted a single-center, retrospective, cohort study of patients prescribed PrEP with emtricitabine-tenofovir disoproxil fumarate from a multidisciplinary clinic with prescriptions filled by Vanderbilt Specialty Pharmacy between 9/1/2016 and 3/31/2019. Patient data were gathered from the electronic health records and pharmacy claims data. We evaluated three different time periods: patient initial evaluation to PrEP initiation, prescription of PrEP to insurance approval, and PrEP insurance approval to initiation. Treatment initiation was considered a delay of > 7 days from initial evaluation, and reasons for delay were recorded. Continuous variables are presented as median (interquartile range, IQR) and categorical variables are presented as percentages. RESULTS: Characteristics of the 63 included patients are in Table 1; most were male (97%), white (84.%), commercially insured (94%) with a median age of 38 years (IQR 29—47). The primary indication for PrEP was men who have sex with men at high risk for acquiring HIV (97%). The median time from initial appointment to treatment initiation was 7 days (IQR 4—8); Figure 1. Treatment delays were observed in 25% of patients and were mostly driven by patient preference (50% of delays). Insurance prior authorization was required in 27% of patients, all of which were approved. Median total out of pocket medication costs for the entire study period were $0 (IQR $0 – $0); Figure 2. Most patients (86%) used a manufacturer copay card.

Though generalizability beyond this population is limited, these results contradict perceived financial barriers to PrEP access. DISCLOSURES: All Authors: No reported disclosures
