Standards status: Trial-use | Maturity Level: 4 | Computable Name: QICoreImagingStudy

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

"Must Have", "QI Elements" and "primary code path" are defined in the QI-Core Must Support section.
QI Elements:

- procedureReference: (QI) The performed Procedure reference
- subject: (QI) Who or what is the subject of the study
- basedOn: (QI) Request fulfilled
- started: (QI) When the study was started
- encounter: Encounter with which this imaging study is associated

Primary code path: procedureCode
(PCPath) This element is the primary code path for this resource CQL Retrieve
Usage

See the patterns page for implementation and usage patterns.
