Use Case overview

This section presents the use cases that the IHE Medication Overview (MEOW) Profile is intended to support. Detailed, step-by-step use-case descriptions are being developed; this overview lists the scenarios that drive the scope of the profile.

Use Case Themes

The profile addresses a range of scenarios in which a patient's medication overview is created, maintained, retrieved and reconciled:

1. General practice - a GP maintains a patient's medication overview and consults it before prescribing.
2. Hospital - medication information is reconciled on admission and at discharge.
3. Patient access - a patient (or their representative) views their own medication overview.
4. Registry / national infrastructure - a regional or national service aggregates medication information from multiple sources.
5. Discharge - a discharge medication list is produced and shared with downstream providers.
6. Substance vs. product - medication is described at the level of substance or of a specific product, depending on what is known.
7. Adherence discrepancy - differences between what was prescribed/dispensed and what the patient is actually taking are recorded.

Two opposite patterns for creating a Medication Overview run through these scenarios:

• the Medication Overview is the source of truth, from which medication requests are derived; and
• the Medication Overview is an aggregation of medication information already present in the patient's records (typically prescriptions and dispenses).

A first detailed use case is presented in Use Case 1.
