| Active as of 2023-08-17 | Computable Name: USPublicHealthExposureContactInformation | |||
This Observation profile represents potential patient exposure and contact information.
The type of exposure/contact is contained in Observation.code (environmental, activity, event, location, person, animal, etc.). If the exposure/contact is an entity (person, animal, location) then it is represented in Observation.focus which is a reference to a Patient, RelatedPerson, Location, Group, etc.. (An animal would be represented by a RelatedPerson that contains the Extension Practitioner Animal Species. Free text information about the exposure/contact can be recorded in Observation.valueString and the date or period of exposure is held in Observation.effective[x]. If an address where the exposure/contact took place is known then it can be contained in the address-extension.
The following are some exposures that might be captured in this profile:
