Clinical Information

Sending and receiving clinical data.


HL7v3 clinical information interfaces are typically used between two clinical systems looking to exchange patient-specific information. Unlike HL7v2 interfaces, HL7v3 interfaces are XML-based and messages are exchanged via Web services.

Outgoing interfaces refer to interfaces in which the Epic system sends the message. Incoming interfaces refer to interfaces in which the Epic system receives the message.

Outgoing QRDA Documents read the specOutgoing QRDA Documents technical specification

Users can create QRDA Idocuments from data in their Epic EHR. Each QRDA I document is specific to one patient and contains data pertinent to quality measure reporting. Each QRDA III document includes aggregated quality measurement data for a provider or group of providers, including the quality measures they are reporting on and their performance rate. QRDA III documents are typically used by providers for quality measure submission. Many regulatory programs, including Meaningful Use, Core Measures, Inpatient Quality Reporting, ORYX Performance Measurement Reporting, and PQRS, accept QRDA documents to satisfy their quality reporting requirements.

Active Guidelines read the specActive Guidelines technical specification

The Active Guidelines (AGL) activity in the Epic EHR uses the HL7 InfoButton standard to allow clinicians to retrieve targeted information provided by third parties, specific to the context of the patient or clinical workflow. Rather than searching third party knowledge base, searches are performed automatically based off elements of the patient's chart like diagnoses or orders.
