Introducing
The HL7® Interface Engine Built for Today’s Healthcare Cloud
We connect you to the networks and platforms that unlock your healthcare data
“
Our customers rely on us for current and accurate patient information at the point of care and we rely on QIE to provide the interoperability and communication between numerous data sources and systems. Easy to use, QIE requires just a single full-time employee to manage more than 300 interfaces.”
Merin Joseph
EVP & CIO – WESTMED Practice Partners
“
One of the best things about Qvera's HL7 interface engine is that we’re able to take data out of our Epic EHR and do what we need to with it. That really makes all the difference ensuring our providers have the data they need in order to provide the highest quality care to our patients.”

Build Interfaces in Minutes, not Hours
Node Path Lookup Dialog – Easily populate node path values using sample messages and a point-and-click user interface
Powerful Node-Path Syntax for Querying Message Data
Instead of writing for-loops and if-statements, get right to the data you need with QIE’s simple, yet powerful, node path syntax for identifying, navigating, and modifying message nodes and sections. Node path syntaxes are available for all data formats, including the following:
HL7 - HPath Examples
message.getNode('PID-5.2')
Returns component 2 of field 5 of the PID segment (Patient First Name)
message.getNode('OBR[@4.1=XR003]-2')
Returns field OBR-2 where the value in OBR-4.1 is equal to ‘XR003’
message.getNode('ORC[group=!ORC]')
Returns the ORC group of segments – adds all segments found to the group until another ORC segment is encountered
XML - XPath Examples
message.getNode('/List/Patient[3]')
Returns the 3rd patient object from a list of patients
message.getNode('/List/Patient[@id=123]')
Returns the patient with the id attribute is equal to ‘123’
message.getNode('/List/Patient[@id=123]/name')
Returns the patient name object where the patient id attribute is equal to ‘123’
JSON - JPath Examples
message.getNode('/Patient/FirstName')
Returns the FirstName field in the Patient object
message.getNode('/Results/[Identifier=’LOI-1968-7′]')
Returns the Result object where the identifier field is equal to ‘LOI-1968-7’
message.getNode('/Results/[Identifier=’LOI-1968-7′]/ObservationValue')
Returns the ObservationValue of the Result object where the identifier field is equal to ‘LOI-1968-7’
DICOM - DPath Examples
message.getNode('/0002,0002')
Returns the Media Storage SOP Class UID from the DICOM message
message.getNode('/0008,0008/[2]')
Returns the 2nd value instance of the Image Type field from the DICOM message
message.getNode('/18,6011/[18,601c=1024]/18,6026')
Returns the Physical Units X Direction (0018,6026) sub-field of the Sequence Of Ultrasound Regions field (0018,6011) where the Region Location Max X 1 (0018,601c) sub-field is equals to ‘1024’
Visual Channel Editor for Rapid Interface Development
Source Nodes: Each channel is created with a single source node which can be configured for receiving data from virtually any source: File, FTP, HTTP, Network Share, Socket, Custom Script, etc.
Mapping Nodes: Mapping nodes are used to perform data manipulations. QIE includes a mapping function wizard for common manipulations to be configured without the need for custom scripts.
Condition Nodes: Condition nodes control how messages are routed through the channel. If the condition is met, the message follows the ‘success’ path. Otherwise, it follows the ‘fail’ path.
Destination Nodes: Destination nodes are used to send messages to downstream systems. QIE supports virtually any connection type: File, FTP, HTTP, Network Share, Socket, etc.
QIE Visual Channel Editor – Quickly map data flow through the interface using QIE’s wire-frame, drag-and-drop visual editor
Step-by-Step Testing with an Integrated Test Environment
QIE’s fully integrated testing framework, simplifies the process of testing proposed configurations and changes, making it easy to see exactly how the changes will effect the interface.
- Step messages through proposed changes, one function at a time, before committing them to production
- Easily view the message state before and after each executed step
- The active channel node is highlighted as the test message is stepped through the interface, showing exactly where it is during each step of the testing process
- Configure multiple sample messages to represent all expected message variations
- Easily create sample messages from actual messages processed by the channel
