Quantity Measurement Observation

[Observation: templateId 2.16.840.1.113883.10.20.6.2.14]

A Quantity Measurement Observation records quantity measurements based on image data such as linear, area, volume, and numeric measurements. The codes in DIRQuantityMeasurementTypeCodes (ValueSet: 2.16.840.1.113883.11.20.9.29) are from the qualifier hierarchy of SNOMED CT and are not valid for observation/code according to the Term Info guidelines. These codes can be used for backwards compatibility, but going forward, codes from the observable entity hierarchy will be requested and used.

  1. SHALL contain exactly one [1..1] templateId ( CONF:9319, CONF:10532 ) such that it
    1. SHALL contain exactly one [1..1] @root="2.16.840.1.113883.10.20.6.2.14"
  2. SHALL contain exactly one [1..1] @classCode="OBS" Observation (CodeSystem: 2.16.840.1.113883.5.6 HL7ActClass) (CONF:9317)
  3. SHALL contain exactly one [1..1] @moodCode="EVN" Event (CodeSystem: 2.16.840.1.113883.5.1001 HL7ActMood) (CONF:9318)
  4. SHALL contain exactly one [1..1] code (CONF:9320)
    1. code SHOULD contain zero or one [0..1] code, which SHALL be selected from ValueSet DIRQuantityMeasurementTypeCodes 2.16.840.1.113883.11.20.9.29 DYNAMIC (CONF:9322)
      1. code SHOULD contain zero or one [0..1] code, which SHALL be selected from ValueSet DICOMQuantityMeasurementTypeCodes 2.16.840.1.113883.11.20.9.30 DYNAMIC (CONF:9323)
        1. SHOULD satisfy: value set of the observation/code includes numeric measurement types for linear dimensions, areas, volumes, and other numeric measurements. This value set is extensible and comprises the union of SNOMED codes for observable entities as reproduced in DIRQuantityMeasurementTypeCodes (ValueSet: 2.16.840.1.113883.11.20.9.29) and DICOM Codes in DICOMQuantityMeasurementTypeCodes (ValueSet: 2.16.840.1.113883.11.20.9.30) (CONF:9330).
  5. SHOULD contain zero or one [0..1] effectiveTime (CONF:9326)
  6. SHALL contain exactly one [1..1] value with data type PQ (CONF:9324, CONF:932)
  7. MAY contain zero or more [0..*] entryRelationship (CONF:9327, CONF:9328, CONF:9329)
    1. Contains @typeCode="SPRT" SPRT
    2. Contains exactly one [1..1] SOP Instance Observation (templateId: 2.16.840.1.113883.10.20.6.2.8)
