Scope of coverage

DEFINITION (OBSERVATION):

The observation resource covers simple as well as complex assertions and measurements made about a patient, specimen, device or other subject.

Fundamentally, observations can be as simple as name/value pair assertions with little structure, as well as observations nested within other observations to represent a rich and complex observation, although there are several resources such as DiagnosticReport to manage and represent aggregation patterns for observations. Expected uses for this resource include:

  • Vital signs: temperature, blood pressure, respiration rate
  • Laboratory Data and other Diagnostic Measures
  • Measurements emitted by Devices
  • Clinical assessments such as APGAR
  • Personal characteristics: height, weight, eye-color
  • Diagnoses (Note: track-able conditions, allergies, adverse reactions and more complex structures are handled elsewhere)
  • Social history: tobacco use, family supports, cognitive status
  • Core characteristics: pregnancy status, death assertion

RIM scope

  • ACT: Observation (ClassCode=OBS and descendants)
  • ACT: Observation (Code=ObservationType)

Resource appropriateness

Observations are a central element in healthcare, used to support diagnosis, monitor progress, determine baselines and patterns and even capture demographic characteristics.
