Documentation

Description:

NHS Digital Application Programming Interfaces (APIs) and specifications provide the definitions, including:

  • how the send and receive messages are constructed
  • how the data within is structured so that it is machinereadable.

The purpose is to ensure that medication and allergy and/or intolerance data is transferred between systems and locations in a machine-readable format. This will be achieved by:

  • transferring medication information using the newest UK version of FHIR (Fast Healthcare Interoperability Resources)
  • the usage of dose syntax to transfer the amount of medication per dose as a simple coded quantity
  • transferring allergy/intolerance information using SNOMED CT and dm+d codes.

Note that it is not assumed that all in-scope locations will implement the standard by 31 March 2023; there will be leeway for those organisations which need to procure and install a suitable IT system.
