QI-Core Implementation Guide
7.0.2 - STU 7

QI-Core Implementation Guide, published by HL7 International / Clinical Quality Information. This guide is not an authorized publication; it is the continuous build for version 7.0.2 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-qi-core/ and changes regularly. See the Directory of published versions

## Resource Profile: QICore Communication

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

Profile of Communication 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:

- topic.extension(codeOptions): (QI) Url of a value set of candidate topics
- sender: (QI) Message sender
- sent: (QI) When sent
- topic: (QI) Description of the purpose/content
- subject: (QI) Focus of message
- received: (QI) When received
- status: (QI) preparation | in-progress | not-done | on-hold | stopped | completed | entered-in-error | unknown
- recipient: (QI) Message recipient

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

The Communication profile defines the conformance expectations for a Communication event, regardless of whether it is a positive or negative statement. To ensure instances retrieved meet positive intent, applications should check the status as illustrated in this example:

    define "Lab results communicated":
       ["Communication": "report-labs"] LabReport
           where LabReport.topic = 'report-labs'
           and LabReport.status = 'completed'
           and LabReport.reasonCode = 'Serum pregnancy test negative (finding)'

Alternatively, applications may make use of the positive and negative profiles to address status. The CommunicationDone and CommunicationNotDone profiles represent the positive and negative statements for a communication event.

To create an expression indicating existence of a communication, use the profile QICoreCommunicationDone; to specifically request information that a communication intentionally did not occur for a medical, patient or system reason, use the profile QICoreCommunicationNotDone.

See the patterns page for implementation and usage patterns.
