## Resource Profile: QICore Encounter

Official URL: http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-encounter | Version: 7.0.2
Standards status: Trial-use | Maturity Level: 4 | Computable Name: QICoreEncounter

Profile of Encounter 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.
Must Have:

- status: (QI) planned | arrived | triaged | in-progress | onleave | finished | cancelled +
- subject: (QI) The patient or group present at the encounter
- class: (QI) Classification of patient encounter
- type: (QI) Specific type of encounter

QI Elements:

- serviceProvider: (QI) The organization (facility) responsible for this encounter
- participant: (QI) List of participants involved in the encounter
- hospitalization: (QI) Details about the admission to a healthcare service
- reasonCode: (QI) Coded reason the encounter takes place
- period: (QI) The start and end time of the encounter
- reasonReference: (QI) Reason the encounter takes place (reference)
- location: (QI) List of locations where the patient has been

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

The following example illustrates accessing an inpatient encounter:

    define "Ophthalmology Encounter Codes":
      [Encounter: class in "Inpatient Encounter Classes"] InpatientEncounter
        where InpatientEncounter.type in "Ophthalmology Encounter Codes"

See the patterns page for implementation and usage patterns.
