FHIR Blood Pressure Profile

This profile was published on Sat, Aug 11, 2018 00:00+1000 as a draft by Health Level Seven HL7 International (Orders / Orders and Observations Workgroup). Observations.

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 14 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.

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
