Resource Profile: Study Variable Summary

Official URL: https://nih-ncpi.github.io/ncpi-fhir-ig/StructureDefinition/study-variable-summary Version: 0.2.0
Draft as of 2022-11-28 Computable Name: StudyVariableSummary

An observation containing summary data associated with research data from FHIR.

Key Guidelines

The Study Variable Summary profile is based on the standard FHIR Observation and is intended to provide summary information for a single variable for either the entire research study, or one of its subgroups. The resource’s code must be set to an appropriate code describing that it’s a summary. The value[x] is set to an appropriate code either from the one of the Study’s data-dictionary tables or a public ontology associated with an appropriate entity to be summarized such as a code from HPO or Mondo. The summary details themselves will be captured in the Observation’s component property.

Added Profile Restrictions

  • In order to clarify the contents of the summary observation, the code MUST include the UMLs code, C0242482, for Summary Report.
  • To ensure uniform usability, the subject MUST only reference NCPI Study Group.
  • Again to enforce uniform behavior, there MUST be at least one focus and that MUST be one of the NCPI Research Study resources.
  • Because the entire purpose of the summary are the contents of the components, there MUST be at least one component.
