Electronic Prescribing and Medicines Administration API standards
Use these API standards to share medication requests between ePMA systems and hospital pharmacy or stock control systems.
Overview
Use these API standards to share medication requests between electronic hospital patient medicines administration (ePMA) systems and hospital pharmacy or stock control systems.
In particular, they define the structure of the FHIR MedicationRequest which acts as a medication order request to the pharmacy for a given patient under care on the ward.
Use the Implementation guide for digital medicines for use cases related to the sharing of medicines data within a trust to support the prescribing, dispensing, and administration of medicines. The guide also covers processes related to medications on admission and discharge. It is based on the FHIR UK Core (R4) standard but can also be applied to FHIR STU3 implementations where key differences between these versions of the FHIR standard are highlighted.
