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

### USCDI+ Quality Element Support Expectations

Systems are expected to support this profile as part of implementing USCDI+ Quality V1 in FHIR and meeting the conformance requirements of this guide.

The following elements are specifically relevant to USCDI+ Quality V1 data classes and elements. Systems are expected to support these elements as applicable to their role in US Quality Core data exchange. See the Must Support section of this guide for more information. These elements are tagged as (USCDI+ Quality) in the formal profile views.

USCDI+ Quality Elements:

- participant: (USCDI+ Quality) (USCDI) Members of the team
- participant.role: (USCDI+ Quality) (USCDI) Type of involvement
- participant.member: (USCDI+ Quality) (USCDI) Who is involved

Because this profile is derived from US Core, systems are also expected to support Must Support requirements and (USCDI) tagged elements inherited from US Core. The Formal Views section also provides the formal summary, definitions, terminology requirements, and mandatory element requirements.

Usages:

- Refer to this Profile: US Quality Core ImagingStudy, US Quality Core NonPatient Observation, US Quality Core Observation Screening Assessment and US Quality Core Simple Observation
- Examples for this Profile: CareTeam/example
- CapabilityStatements using this Profile: US Quality Core Client CapabilityStatement and US Quality Core Server CapabilityStatement

You can also check for usages in the FHIR IG Statistics
