Dose syntax implementation guidance for FHIR STU3

This guidance is under active development by NHS Digital and content may be added or updated on a regular basis.

Free-text instruction examples

These medicationRequest examples require use of free-text intructions that cannot be represented using the coded elements of the Dosage structure. Therefore these examples cannot be fully machine readable and would require human interpretation to ensure the free-text instructions are adhered to, and they do not contradict the coded instructions.

Important: Examples are not complete with respect to all required data for a CareConnect implementation but instead highlight the variety of use of the FHIR Dosage structure

Microgynon 30 tablets (Bayer Plc), 1 tablet, ONCE a DAY, oral, for 21 days, subsequent courses repeated after 7-day tablet-free interval

Product-based AMP prescription using additional instructions to convery pill free interval.

STU3 Dosage current limiation - Specific instructions related to combination products

Phenoxymethylpenicillin 250mg tablets, 2 tablets every 6 hours an hour before food or on an empty stomach, oral

Product -based prescription (VMP) using free text additional instruction.

Complex because “on an empty stomach” is not a coded SNOMED-CT code nor in a FHIR value-set.

To avoid confusion with a coded “before food”, the complete instruction “an hour before food or on an empty stomach” is conveyed as free-text within additionalInstruction.
