How EPM Works: A Step-by-Step Overview

The process of electronic prescribing is designed to be seamless and secure:

1. Prescription Creation: The healthcare provider accesses the EPM module within their EHR or standalone e-prescribing software. They select the patient, search for the desired medication from a comprehensive drug database, specify the dosage, frequency, route, and duration, and add any specific instructions.
2. Clinical Decision Support: As the prescription is being created, the EPM system automatically performs real-time checks for drug-drug interactions, drug-allergy interactions, duplicate therapy, and appropriate dosing based on patient demographics (age, weight, kidney function, etc.). If a potential issue is detected, an alert is displayed, prompting the prescriber to review or modify the order.
3. Patient and Pharmacy Selection: The provider confirms the patient's identity and selects their preferred pharmacy from a directory. The system may also allow the patient to choose their pharmacy during a virtual visit.
4. Secure Transmission: Once the prescription is finalized and approved by the prescriber, it is digitally signed and securely transmitted over an encrypted network to the chosen pharmacy.
5. Pharmacy Processing: The pharmacy receives the electronic prescription directly into its dispensing system. Pharmacists review the order for accuracy, perform their own checks, and prepare the medication for dispensing.
6. Patient Notification: Many EPM systems can send automated notifications to patients (via text or email) when their prescription has been sent and when it is ready for pickup, enhancing patient convenience.
