FHIR Blood Pressure Profile

This profile was published on Sat, Aug 11, 2018 00:00+1000 as a draft by Health Level Seven International (Orders and Observations Workgroup).

Description of Profiles, Differentials, Snapshots, and how the XML and JSON presentations work.

This structure is derived from Observationvitalsigns.

Summary

  1. One code in Observation.code which must have
    • a fixed Observation.code.coding.system='http ://loinc.org'
    • a fixed Observation.code.coding.code= 85354-9'
    • Other additional Codings are allowed in Observation.code- e.g. more specific LOINC Codes, SNOMED CT concepts, system specific codes. All codes SHALL have a system value
  2. One Observation.component.code which must have
    • a fixed Observation.component.code.coding.system='http://loinc.org'
    • fixed Observation.component.code.coding.code= '8480-6'
    • Other additional Codings are allowed in Observation.code- e.g. more specific LOINC Codes, SNOMED CT concepts, system specific codes. All codes SHALL have a system value
  3. One Observation.component.code which must have
    • a fixed Observation.component.code.coding.system='http://loinc.org'
    • fixed Observation.component.code.coding.code= '8462-4'
    • Other additional Codings are allowed in Observation.code- e.g. more specific LOINC Codes, SNOMED CT concepts, system specific codes. All codes SHALL have a system value
  4. Either one Observation.valueQuantity or, if there is no value, one code in Observation.DataAbsentReason
    • Each Observation.valueQuantity must have:
      • One numeric value in Observation.valueQuantity.value
      • a fixed Observation.valueQuantity.system="http://unitsofmeasure.org"
      • a UCUM unit code in Observation.valueQuantity.code = 'mm[Hg]'

Mandatory: 11 elements (+8 nested mandatory elements)
Must-Support: 8 elements
Fixed Value: 10 elements
Prohibited: 1 element

Slices

This structure defines the following Slices:

  • The element Observation.code.coding is sliced based on the values of value:code, value:system
  • The element Observation.component is sliced based on the values of value:code.coding.code, value:code.coding.system
  • The element Observation.component.code.coding is sliced based on the values of value:code, value:system

This indicates the differences between this profile and the base Observationvitalsigns structure.

Summary

  1. One code in Observation.code which must have
    • a fixed Observation.code.coding.system='http ://loinc.org'
    • a fixed Observation.code.coding.code= 85354-9'
    • Other additional Codings are allowed in Observation.code- e.g. more specific LOINC Codes, SNOMED CT concepts, system specific codes. All codes SHALL have a system value
  2. One Observation.component.code which must have
    • a fixed Observation.component.code.coding.system='http://loinc.org'
    • fixed Observation.component.code.coding.code= '8480-6'

    • fixed Observation.component.code.coding.code= '8462-4'
    • Other additional Codings are allowed in Observation.code- e.g. more specific LOINC Codes, SNOMED CT concepts, system specific codes. All codes SHALL have a system value
  4. Either one Observation.valueQuantity or, if there is no value, one code in Observation.DataAbsentReason
    • Each Observation.valueQuantity must have:
      • One numeric value in Observation.valueQuantity.value
      • a fixed Observation.valueQuantity.system="http://unitsofmeasure.org"
      • a UCUM unit code in Observation.valueQuantity.code = 'mm[Hg]'

Slices

This structure defines the following Slices:

  • The element Observation.code.coding is sliced based on the values of value:code, value:system
  • The element Observation.component is sliced based on the values of value:code.coding.code, value:code.coding.system
  • The element Observation.component.code.coding is sliced based on the values of value:code, value:system
