FHIR Vital Signs Profile

This profile was published on Fri, Mar 25, 2016 00:00+0000 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 Observation.

Summary

"#### Complete Summary of the Mandatory Requirements

  1. One status in Observation.statuswhich has a required binding to:

  2. A category in Observation.category which must have:

    • a fixed Observation.category.coding.system="http://terminology.hl7.org/CodeSystem/observation-category"
    • a fixed Observation.category.coding.code= "vital-signs"
  3. A code in Observation.code

    • a fixed Observation.code.coding.system= "http://loinc.org""
    • a LOINC code in Observation.code.coding.code which has an extensible binding to:
  4. One patient in Observation.subject

  5. A date and time in effectiveDateTime or effectivePeriod

  6. Either one Observation.value[x] or, if there is no value, one code in Observation.DataAbsentReason

    • if a vital sign measure then:
      • One numeric value in Observation.valueQuantity.value
      • a fixed Observation.valueQuantity.system="http://unitsofmeasure.org"
      • a UCUM unit code in Observation.valueQuantity.code which has an required binding to the Vital Signs Units value set.
    • Observation.DataAbsentReason is bound to Observation Value Absent Reason value set.
  7. When using a panel code to group component observations (Note: See the comments regarding blood pressure in the table above), one or more Observation.component.code each of which must have:

    • a fixed Observation.component.code.coding.system =""http://loinc.org""
  8. Either one Observation.component.valueQuantity or, if there is no value, one code in Observation.component.DataAbsentReason

  9. When using a panel code to group observations, one or more reference to Vitals Signs Observations in Observation.related.target

    • a fixed Observation.related.type= "has-member""

Mandatory: 9 elements (+1 nested mandatory element)
Must-Support: 15 elements
Fixed Value: 2 elements

vs-2ObservationIf there is no component or hasMember element then either a value[x] or a data absent reason must be present.
Expression : (component.empty() and hasMember.empty()) implies (dataAbsentReason.exists() or value.exists())
vs-1Observation.effective[x]if Observation.effective[x] is dateTime and has a value then that value shall be precise to the day
Expression : ($this as dateTime).toString().length() >= 8
obs-3Observation.referenceRangeMust have at least a low or a high or text
Expression : low.exists() or high.exists() or text.exists()
vs-3Observation.componentIf there is no a value a data absent reason must be present
