Resource Profile: VA PGHD Observation Profile for Mobile App Data in Anthropometric Category

Official URL: https://veteran.apps.va.gov/smart-pgd-fhir/v2/StructureDefinition/va-pghd-observation-category-anthropometric Version: 2.1.27
Active as of 2023-03-01 Computable Name: VAPghdObservationProfileCategoryAnthropometric

VA PGHD Observation profile for mobile app data in anthropometric category of the mobile-observation-category valueset. Codes can be from the standard code systems.

This profile is required by SMHD app to validate the use of the recommended valuesets in creating anthropometric measurement observation resource.

Usages:

  • This Profile is not used by any profiles in this Implementation Guide

You can also check for usages in the FHIR IG Statistics
