Active as of 2026-06-05 | Computable Name: USQualityCoreDeviceUseStatement

Profile of DeviceUseStatement for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

### USCDI+ Quality Element Support Expectations

This profile does not include USCDI+ Quality flagged elements and is not in scope for USCDI+ Quality V1 conformance requirements in this guide. See the USCDI+ Quality page for the list of profiles and elements that are in scope for USCDI+ Quality V1.

This profile is inherited from QI-Core v6.0.0 and is included to ease adoption for systems that currently support QI-Core. Refer to the Formal Views section for the formal summary, definitions, terminology requirements, and mandatory element requirements.

Usages:

- Examples for this Profile: DeviceUseStatement/example
