10.1.17.28.1 Formal Views of Profile Content

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

This structure is derived from Vital Signs Profile.

Summary

10.1.17.28.2 Complete Summary of the Mandatory Requirements

  1. One code in Observation.code which must have
    • a fixed Observation.code.coding.system='http ://loinc.org'
    • a fixed Observation.code.coding.code= '8306-3'
    • Other additional codes are allowed - e.g. more specific LOINC Codes, SNOMED CT concepts, system specific codes. All codes SHALL have an system value
  2. a fixedObservation.valueQuantity.code = 'cm', or '[in_i]'

Fixed Value: 2 elements

Slices

This structure defines the following Slices:

  • The element Observation.code.coding is sliced based on the value of code
