Specialty pharmacy integration and the role of an advanced certified pharmacy technician in prescription cannabidiol access

Abstract

Background: Insurance requirements that limit access to prescription cannabidiol (CBD), an adjunct therapy for uncontrolled seizure disorders, may lead to treatment initiation delays. Integrated health-system specialty pharmacies (IHSSPs) use pharmacists and advance certified pharmacy technicians (CPhTs) to help navigate prescription CBD access requirements.

Objective(s): Evaluate time from initial specialty pharmacy referral to prescription CBD shipment.

Methods: This was a single-center, retrospective analysis of patients prescribed CBD from January 2019 to April 2020 by the outpatient neurology clinic and dispensed by the center's IHSSP. The primary outcome was the time to prescription CBD access, defined as days between the specialty pharmacy completing an initial patient assessment and first medication shipment. Secondary outcomes were percentage of patients requiring financial assistance and days between key steps in the access pathway. Data were collected from electronic health records and the specialty pharmacy patient management database. The CPhT was responsible for completing most portions of the access pathway under supervision of the clinical pharmacist.

Results: After screening, 136 patients were included: 50% male, 85% white, 60% insured by Medicaid, and median age 14 years (interquartile range [IQR] 9-21). The most common indication was Lennox-Gastaut syndrome (n = 117, 86%). Of the 129 patients (95%) who required a prior authorization (PA), 92% were approved (n = 119). Median time from initial assessment to first shipment was 7 days (IQR 4-13). Of patients for whom the CPhT helped obtain financial assistance (n = 14, 10%), all had $0 costs after assistance. Median times for secondary outcomes led by the CPhT in days were as follows: initial assessment completion to benefits investigation (BI) = 0 (IQR 0-0), BI to PA submission = 0 (IQR 0-0), and PA denial to appeal submission = 4 (IQR 1-7).

Conclusion: IHSSP teams, particularly advanced CPhT roles, helped patients afford and initiate prescription CBD quickly.
