clinicalStatus
A value from a required terminology binding containing the values;
active
inactive
resolved
.The FHIR standard states this element SHALL be present if verificationStatus
is not entered-in-error
, but SHALL NOT be present if verificationStatus
is entered-in-error
.
Provider systems MUST provide this data.
Consumer systems MUST consume this data.
A recorded allergy may be subsequently proven to have a different clinical status, e.g. from active
to inactive
. In this scenario provider systems should create a new instance of this resource to reflect the change of clinical status.
This is opposed to updating the existing instance of the resource. This resource has no data element that could convey a last updated date. Also the action of updating the resource may not be picked up by consumer systems. Creating a new instance of the resource is the safer implementation approach.
