description: An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research subject. The unintended effects may require additional monitoring, treatment or hospitalization or may result in death. The AdverseEvent resource also extends to potential or avoided events that could have had such effects. package_name: hl7.fhir.r5.core derivation: specialization name: AdverseEvent type: AdverseEvent
