Resource Profile: Observation Base

Defining URL:http://hl7.org/fhir/uv/eyecare/StructureDefinition/observation-base
Version:0.1.0
Name:ObservationBase
Title:Base Observation for Ophthalmology
Status:Draft as of 2021-08-12T15:09:12+00:00
Definition:

A profile describing an Observation for ophthalmology

Publisher:HL7 International - Patient Care WG
Source Resource:XML / JSON / Turtle

The official URL for this profile is: 

http://hl7.org/fhir/uv/eyecare/StructureDefinition/observation-base

The observation base profile supports the common requirements for all ophthalomology observations.

  • Observations.status - restricted valueset to only final result states.
  • Observation.category - all observations are in the ‘exam’ category
  • Observation.subject - only for individual patients, use local profiles for patient such as US Core Patient, AU Base Patient or other relevant profile.
  • Laterality extension - ophthalmic laterality to support laterality independently of body site.
