Resting ECG Workflow (REFW)

Profile Overview

REWF Profile Scope

Reporting workflow management

Clinical trial workflow

  • Patient registration

  • Ordering and scheduling

  • Acquisition

  • Data storage

  • Data retrieval for reporting

  • Report distribution

Use cases
Use Cases

  • Normal Priority, Scheduled ECGs

    • Patient is registered

    • ECG is ordered, scheduled, acquired, stored, reviewed, and reported

  • Urgent ECG, Unidentified Patient

    • Unordered ECG

    • Patient demographics reconciliation

  • Scheduled ECG While Offline

    • Order reconciliation

  • Other Cases Not Completely Covered

    • Patient Demographics for Unscheduled ECGs

      • Acquisition Modality should be grouped with PDQ Consumer

    • Clinical Trials

      • Much thought was given to clinical trial workflow, but it deserves its own profile in a future year

    • Physician Offices

      • ECGs are often (implicitly) ordered and acquired in a single step while a patient is being examined

      • The new Image Enabled Office profile covers office-based ECG workflow

Related profiles
Related Profiles

  • RAD SWF - Scheduled Workflow

    • Patient registration

    • Test ordering and scheduling

    • Acquisition and data storage

    • Data retrieval

  • RAD PIR - Patient Information Reconciliation

    • Urgent ECGs acquired on unknown patients

  • ITI CT - Consistent Time

    • Synch Acquisition Modality’s clock

  • ITI PDQ - Patient Demographics Query

    • Acquisition Modality can query for demographics

  • CARD DRPT - Displayable Reports

    • Distribute ECG reports

  • CARD IEO - Image Enabled Office

    • Workflow in an office environment


  • Allows multi-vendor interoperability between 5 major subsystems:

    • Registration and ordering (HIS, CVIS)

    • ECG archival (PACS, ECG Management)

    • Acquisition devices (Electrocardiographs)

    • ECG analysis and reporting workstations (ECG or PACS Workstations)

    • ECG report consumers (EMR)

  • Uses HL7 transactions for HIS and EMR.

  • Uses DICOM transactions for acquisition devices and workstations

  • ECG waveforms stored as DICOM General ECG Waveform objects

  • ECG measurements and interpretations stored as DICOM Structured Reports

  • An “Integrated ECG Manager” actor makes it easier for traditional ECG management products to adopt this profile.

Familiar actors and transactions
Familiar Actors and Transactions

  • Actors reused from other profiles:

    • ADT (SWF)

    • Order Placer (SWF)

    • DSS/OF (SWF)

    • Image Manager / Image Archive (SWF)

    • PPS Manager (SWF)

    • Acquisition Modality (SWF)

    • Evidence Creator (SWF)

    • Image Display (SWF)

    • Time Client (CT)

    • Report Creator (DRPT)

    • Report Manager (DRPT)

Integrated ecg manager actor
“Integrated ECG Manager” Actor

  • Integrated ECG Manager is an optional integration of the actors in the “middle”

  • Makes it easier for traditional ECG management products to adopt this profile without having to expose transactions between the integrated actors

  • Individual actors are still present so traditional departmental management and archive products can treat Resting ECG Workflow like other scheduled workflows

New and modified transactions
New and Modified Transactions

  • CARD-2 Modality Images/Evidence Stored

    • Acquisition Modality and Image Archive actors must be able to store General ECG Waveform and Enhanced SR (ECG Report template)

  • CARD-4 Retrieve Images/Evidence

    • Report Creator and Image Display actors must be able to display General ECG Waveform and Enhanced SR (ECG Report template)

  • CARD-7 Encapsulated Report Submission

    • Specifies displayable Resting ECGs (PDFs) should meet minimum display requirements

    • Basic measurements and interpretation should be included as discrete data in OBX segments

  • New: CARD-12 Query Enhanced Modality Worklist

    • Patient queries can also match on Admission ID

    • Broad queries can also match on Scheduled Procedure Step Location

  • New: CARD-13 Query Cardiology Images/Evidence

    • Query returns Performed Protocol Step Code Sequence to distinguish General ECG Waveform objects used for resting ECG from other tests and monitoring sessions
