Describing the Medicine The Importance of the correctly describing a Medicine HL7 Information Model (the RIM) for messaging Realm-specific (use case driven) Terminology Model for description The need for Harmonisation The Medication CMETs (harmony, not melody)

Material Medicinal Product - Universal The medicine entity plays the role of “ordered medicine” Equivalent concepts (e.g. brand/generic) can be represented here The medicine’s ingredients can be represented using the role of “ingredient strength” and “ingredient” entities The medicine’s manufacturer can be represented using the role of “manufactured by” and “manufacturer” entity

Material Medicinal Product - Identified Just carry the dm+d identifier for the medicine in here

Material Medicinal Product Pack - Universal The supplied medicine entity plays the role of “supplied medication” The supplied medicine entity has batch number and expiry information; it will be a dm+d AMPP code The supplied medicine entity scopes the role of “pack of”

Material Medicinal Product Pack - Identified Just carry the dm+d identifier for the AMPP in here

Route of Administration & Dosage Information Mood = Request Effective time = when to give (frequency) Route code = dm+d route of administration code Dose quantity = how much of the medicine to give [Rate quantity – for a rate, rather than a unit dose] Additional textual instructions, if required

The UKCPRS Programme The “dm+d” – the NHS Dictionary of Medicines and Devices –Modelled vocabulary of medicinal product concepts –Supporting vocabulary of ingredient, dose forms, suppliers –Supporting vocabulary of dosage syntax (separate deliverable)

dm+d – a modelled vocabulary

The “Five Core Classes” of dm+d

Using the dm+d codes for Pharmacy CMETs ProposePromiseRequestEvent Medicine Entity Code (Ordered Medicine) VTM, VMP, VMPP, AMP, AMPP AMPP Supplied Medicine Entity Code (Supplied Medication) AMPP

dm+d – Supporting Attribute Vocabulary Dose Form vocabulary Ingredient vocabulary Route of Administration vocabulary Manufacturer or supplier vocabulary

Dosage Syntax A deliverable from a separate UKCPRS/HL7 Med Info SIG workstream –A standardised, modelled structure and vocabulary to describe medication dosage for electronic systems –Will “fit” into the Substance Administration act sections to message dosage instructions
