0. EHDSAlertFlag
Definition | C.22 - EHDS refined base model for Alert flag Base definition for all types defined in FHIR type system.
Short | Alert flag modelBase for all types and resources
Control | 0..*
Is Modifier | false
Logical Model | Instances of this logical model are not marked to be the target of a Reference
2. EHDSAlertFlag.identifier
Definition | Flag identifier (Business identifiers assigned to this flag).
Short | C.22.1 - Identifier
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
4. EHDSAlertFlag.text
Definition | A human-readable narrative that contains a summary of the flag and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Example 1: intolerance to aspirin due to gastrointestinal bleeding. Example 2: intolerance to captopril because of cough (the patient is not allergic but can't tolerate it because of persistent cough) Example 3: the patient has a rare disease that requires special treatment Example 4: Airway Alert / Difficult Intubation Example 5: Diagnoses such as malignant hyperthermia, porphyria, and bleeding disorders; special treatments like anticoagulants or immunosuppressants; implanted devices. Example 6: transplanted organs illustrate other information that has to be taken into account in a healthcare contact. Example 7: participation in a clinical trial that has to be taken into account in a healthcare contact.
