Extension

Short Prevention Instructions Extension
Definition The instructions given to the patient in connection with this prevention: what to do, watch for, or come back for after it was administered or performed. This is what the patient was told, not how the product was given. The administration itself is described by Immunization.route, Immunization.site and Immunization.doseQuantity, all coded. This element carries the aftercare sentence -- "observe 15 minutes", "return if swelling persists past 48 hours" -- which is written for a person and is not drawn from any value set. It is not a clinical comment. The resource's note is where a person's remarks about the record live, and a consumer is entitled to render every note repeat verbatim as a comment. This is a distinct field with its own editing lifecycle, which is why it has its own address. At most one per resource. A reader meeting more than one should take the first. MIGRATION. Write this extension. A reader of records written before this extension existed may find the same information carried as free text inside the resource's note; that carriage is not part of this specification, is not produced going forward, and a consumer that wants it from older records has to read it from where it was written. Moving the existing data is outstanding work and is not described here.

Extension.extension

Short Additional content defined by implementations
Definition May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
