## Logical Model: CRD Metric Data

Official URL: http://hl7.org/fhir/us/davinci-crd/StructureDefinition/CRDMetricData | Version: 2.2.1 | Highlight text changes?
Standards status: Informative Active as of 2026-03-26 | Maturity Level: 1 | Computable Name: CRDMetricData
Other Identifiers: OID:2.16.840.1.113883.4.642.40.18.42.1

A logical model describing the information that should be captured by CRD implementers about every CRD invocation to support measures evaluating CRD implementation

This model is NOT a FHIR data structure for information exchange. Instead, it is a logical model of the information that ought to be collected and maintained for each CRD transaction. While implementers may choose any internal storage format that is appropriate for their system, the information collected should ultimately be mapped to the information model below.

Mapping implementation data to these elements will allow metrics (see the table on the metrics page) to be represented in a way that provides consistent responses to requirements from various interested parties (providers, payers, regulators, quality organizations, certification agencies, states, etc.) by each of the participants in the CRD exchanges.

Usages:

- This Logical Model is not used by any profiles in this Implementation Guide
