Summary

This standard will include support for Prescribing, Dispensing and Administration messages, as well as Rx status management, active medications and patient Rx queries. This domain is used to derive message patterns to describe and communicate processes related to medication. The primary real life processes being represented are the making of a prescription or medication order, the organizing of a supply of a medication and the administration of the medication to a patient. It differs from the Medication domain (POME) which defines the overall description of a medicine.

Description

The Medication Order topic deals with all content related to the ordering of medications, both for dispensing (supply) and for administration. It is intended to cover community prescribing, discharge prescriptions and institutional medication orders. The models are intended to support the requirements of all jurisdictions.

The Medication Dispense and Supply Event topic covers the issuing of medication to a patient or representative, as well as bulk supplies of medication.

The Medication Statement topic deals with the recording of statements about which medications the patient has received or is recveiving through mechanisms other than a prescription, dispense or administration. Examples include over the counter medications and patient statements (e.g. patient informs physician of a medication received while on vacation).

The Drug Knowledge-Base Query topic covers the issuing of queries to drug knowledge base applications for such information as drug monographs, regimens and therapies.

As a high level model, it may not appear to mimic exactly real life objects or classes. Analysis of the way this real life process works in systems terms requires some of the real life objects to be represented as more than one class: for example a prescription can be viewed as a "header" with a medication administration and supply order. We also have to recognize that each class will progress through a number of distinct moods before the business process is complete eg. substance administration in the mood of order (as on a prescription) and also substance administration in the mood of event (as in a notification of administration). Overall the DMIM is a tool to assist the process of generating specific pharmacy message models and is not intended to be used by those unfamiliar with HL7 Version 3 modeling.

Business Case (Intended Use, Customers)

  • Vendors: Healthcare IT
  • Vendors: Pharmaceutical
  • Providers: Pharmacy
  • Providers: Healthcare Institutions

Benefits

This standard allows for consistent communication of a Medication Process. It can communicate using a role as the "header" (something that can be used to "hold together" the other acts of substance administration and supply) that are intimately related and in some senses equally important in the clinical process for a Pharmacy communication. Its messages also function as a holder for information related to the whole process of adminstration and supply. It can be used as a representation of a "prescription" or of a "line item" and indeed when necessary may be cloned and unrolled to represent both a prescription and a line item within the prescription.
