Evaluating trends in pharmacist e-prescribing: 2019-2022

Background: Pharmacists have some prescriptive authority in all fifty states through dependent and independent prescribing. Data describing the volume and characteristics of pharmacist prescribing are not widely available, and these insights are critical to gauge the impact of regulations supporting pharmacist prescriptive authority. Objective: To identify trends in pharmacist prescribing and compare them to primary care provider (PCP) prescribing trends by analyzing e-prescriptions initiated from electronic health records systems from 2019 through 2022. Methods: This cross-sectional study used e-prescriptions from a national health information network to identify e-prescriptions ordered by pharmacists and PCPs from January 7, 2019, to January 1, 2023. E-prescriptions ordered by pharmacists and PCPs were analyzed to identify annual volume by prescriber type and most prescribed therapeutic classes. States with the highest volume of e-prescriptions ordered by pharmacists were identified. Results: The number of e-prescriptions prescribed by a pharmacist increased 47% from 2019 (n = 814,726) to 2022 (n = 1,199,601). The number of pharmacists prescribing in 2019 was 1650, and this increased by 122% to 3664 in 2022. The number of e-prescriptions prescribed by PCPs increased by 4% from 2019 (n = 927,890,123) to 2022 (n = 965,803,376) while the number of PCPs prescribing increased by 8% from 2019 (n = 364,995) to 2022 (n = 394,753). Conclusion: Pharmacist e-prescribing increased across the 4 years studied while PCP e-prescribing modestly increased. Factors like access to technology, such as electronic health records, state regulations, and reimbursement impact a pharmacist's ability to prescribe. (c) 2024 American Pharmacists Association (R).
