Allergies

This implementaion guide include the following resources for allergies.

Clinical scenario: producing an Allergy List

In this scenario, a patient is admitted as an inpatient; allergies are made available from several sources in varing quality. The end user will need to refine this prior to precribing. The allergies are presented,checked and the current allergies list is created.

The purpose of these examples is to illustrate FHIR usage based on a simple clinical scenario.

1) Prior to admission

If degraded allergies are recorded then steps will need to be taken during admission to make the record safe prior to treatment or prescription. The degraded allergies will need to be coded correctly and updated. No list exists at this stage and the query specified it should be returned if present.

All Allergy information available- no current list exists
  • Potato
  • Asprin, Ibuprofen (transfer degraded)
  • Aspirin
  • Wasps (transfer degraded)
  • Morphine/oramorph (transfer degraded)

2) After admission

The allergy information has been refined by the user by consulting with the patient and finding equivalent coded substances and finding or disorders. Each allergy resource is updated as these changes occur. No current list need exist at this stage.

All Allergy information refined- items corrected
  • Potato
  • Ibuprofen
  • Aspirin
  • Wasp
  • Morphine

3) On discharge or transfer

After the visit the patient's medications and allergies form a part of the discharge or transfer message. To encapsulate the current view at the point of dischange a current allergy list is generated and added to, or referenced by, outbound messaging.

Current Allergy list generated
  • Potato
  • Ibuprofen
  • Aspirin
  • Wasp
  • Morphine

Clinical scenario: updating an Allergy List

In this scenario, a patient is admitted as an inpatient; allergies are made available from an existing allergy list. The end user needs to update the list to add a newly discovered allergy and to update any existing items to make the list conformal.

1) On admission

The user has been presented with a list of no known allergies, meaning it's understood the user has no allergies.

2) During admission

The patient informs the user that they recently had a reaction to strawberries. The user must soft delete the no known allergies entry, add the strawberry allergy and update the current list.

3) On discharge or transfer

After the visit the patient's medications and allergies form a part of the discharge or transfer message. To encapsulate the current view at the point of dischange the current allergy list is added to, or referenced by, outbound messaging.
