Attributes

Own

  • id 1..1
    • Description: The 'logical' identifier of the entity within the system of record. The simple value of this attribute stands for an identifier of this data object within the system, it can be used as a reference from other objects within the same system (i.e. primary and foreign keys), and it should be unique per type of object. The same data object copied to a different system will likely have a different "id" in the new system since "id" values are system specific and do not represent persistent business identifiers. Business identifiers are assigned outside the information system and are captured in the "identifier" field. The "id" field is more likely to be a serially or randomly generated value that is assigned to the data object as it is created in a system.
    • Range: CrdchString
  • category 1..1
    • Description: The general category of observation set described
    • Range: CodeableConcept
    • Examples: DimensionalMeasureSet, TissueCompositionMeasureSet, CellularCompositionMeasureSet
  • focus 0..*
    • Description: The entity or entities directly observed/measured in generating an observation result.
    • Range: Entity
  • subject 0..1
    • Description: The patient that the observation is about (if not the direct focus). e.g. observations are often made on specimens derived from a patient, or other entities related to a patient, that ultimately tell us something about the patient of interest.
    • Range: Subject
  • method_type 0..*
    • Description: A type of method used in generating each of the Observations bundled in the set.
    • Range: CodeableConcept
  • performed_by 0..1
    • Description: The organization or group that performed the observation activity.
    • Range: Organization
  • observations 0..*
    • Description: A set of one or more more atomic observations that are conceptually or logically related - e.g. two components of some compound measurement (e.g. the systolic and diastolic components of a blood pressure measurement), or a panel of related measurements run and interpreted together on the same subject/specimen (e.g. a blood panel, or separate dimensional measurements of a specimen).
    • Range: Observation

Other properties
Comments: An Observation Set is comprised of one or more logically related Observations made about the same entity. The Observations in a set may be grouped because they were generated on a single occasion using a common methodology (e.g. a blood panel), and/or or because describe aspects of the same underlying feature of an entity and as such are considered together as a logical unit of information (e.g. diastolic and systolic measures that comprise a blood pressure observation, or T, N, and M components of a Cancer Staging observation).
