*LOINC codes are the recommended coding system for the FHIR observation.code element but the observation.code being a CodableConcept, one may choose also to use SNOMED CT concepts to represent the value in this field.

A review of systems fails to reveal any other causes and the physician believes that the patient may be having an urticarial reaction to penicillin. He has lingering uncertainty about this and tells the patient to stop the penicillin and employ diphenhydramine for relief. He schedules him back in a week for follow-up and when recording his note for the visit, he adds to his assessment in the problem list: “Moderate urticarial reaction, possible penicillin allergy”.

Scenario: Several years later, the same patient from scenario 4.1 who has since received an aortic valve replacement is seeing another physician within the organization for consultation on antibiotic prophylaxis for an upcoming dental procedure. The second physician decides that a penicillin class antibiotic is appropriate for the patient.

Scenario: The patient from the initial scenario 4.1 is planning a vacation with his family consisting of a cross-country camping trip.  In preparation for travels, he speaks to his physician in hospital A and obtains an electronic summary of his healthcare record on a flash drive for himself, his wife and children. His physician informs him that the summary software includes an electronic ‘reader’ as well as a standard format that can be imported into another EHR for patient care.  Their vacation unfolds happily until, many miles from home the patient experiences an episode of right ear pain and is taken to a local emergency room in hospital B.  He provides the flash drive with his electronic record summary to the emergency room physician whose hospital employs an EHR which can accept FHIR extracted electronic record summaries for integration into the on-site health record system.  The emergency room nurse loads the flash drive and accepts the electronic copy of the problem list, allergies and medication list into the on-site record.  The software extract manages the differences in information model design between EHR vendors by crosschecking the allergy list with information in the problem list and encounter diagnoses.
