ePrescriptions

Electronic prescriptions, or e-prescriptions, are digitally generated prescriptions transmitted from a prescriber to a pharmacy through a secure network. They typically occur within an electronic health record system, a stand-alone e-prescribing program, or a pharmacy’s software. The content mirrors a traditional prescription, including patient details, medication name, dosage, route, directions, quantity, refills, and prescriber identification.

Workflow and benefits: The prescriber creates the Rx, and the system performs checks against the patient’s formulary, allergies, and potential drug interactions. The prescription is sent electronically to the patient’s chosen pharmacy, where staff can verify and dispense it. Benefits include improved legibility, fewer transcription errors, faster dispensing, integrated clinical decision support, easier refill management, and streamlined administrative tasks.

Standards and security: In the United States, the NCPDP SCRIPT standard governs e-prescriptions, with transmissions routed through e-prescribing networks or health information exchanges. For controlled substances, electronic prescribing requires electronic prescribing for controlled substances (EPCS), which uses two-factor authentication and digital certificates. Data privacy and integrity are supported by encryption, authentication, and access controls.

Regulation and adoption: Many countries promote e-prescribing through national or regional health IT initiatives. In the US, e-prescribing expanded with electronic health records and incentives under meaningful use programs, and there are ongoing efforts to improve interoperability and coverage across payers and providers. Adoption levels vary by country, system, and regulatory environment.

Limitations and challenges: Not all prescriptions are suitable for electronic transmission, and some patients lack access to compatible systems. Interoperability between vendors can be uneven, with occasional downtime, usability issues, and ongoing concerns about privacy and data security.
