Retrieve ECG for Display

This integration profile provides access throughout the enterprise to electrocardiogram (ECG) documents for review purposes

Summary

Clinicians need a simple means to access and view electrocardiograms (ECGs) from anywhere within and beyond the hospital enterprise. The ECGs should consist of “diagnostic quality” waveforms, measurements, and interpretations. The primary goal is to retrieve resting 12- lead ECGs, but retrieving ECG waveforms gathered during stress, Holter, and other diagnostic tests is also desirable. Typically, these ECGs are already stored in an ECG management system. The focus of this Profile is on retrieval and display, not the process of ordering, acquiring, storing, interpreting, or analyzing the ECGs.

Benefits

IHE provides benefits to clinicians and administrative staff focusing on patient care and reducing inefficiencies, specifically:

• Make ECG viewing available in many locations, increasing the access to the ECG information
• Simplify and standardize the ECG access and viewing process
• Remove the need to “find the printed ECG” (lost on a piece of paper or moving to a special ECG-only workstation)
• Allow multiple clinicians to view the ECG simultaneously for real-time conferencing
• Provide diagnostic display resolution
• Allow clinicians to view ECGs from outside of the physical hospital walls (in coordination with hospital security policies)
• Reduce the need for duplicate procedures
• Ensure that a multi-vendor environment will function correctly
• Manage and simplify the purchasing process
• Reduce “switching costs” when a new system is purchased
• Select the “best solutions” from multiple vendors and reduce vendor integration issues rather than restriction to a single vendor allencompassing solution

Details

<A few paragraphs, if appropriate, providing more details (mostly in user-speak, not tech-speak) on what the profile does and how it works.>

<If the user might be familiar with the mechanisms used by the profile, you can mention them here. E.g. Evidence Documents is based on DICOM Structured Report (SR) Templates.>

<If the user might have an appreciation for the problems addressed in the profile, you can mention them here, but keep it short. E.g. Mapping HL7 Order fields to DICOM Modality Worklist attributes can be inconsistent in the marketplace, so Scheduled Workflow provides vendors with more detailed instructions.>

Systems Affected

The key Actors in ECG Display and examples of real-world products which might implement these roles are:

• Display – Electronic Healthcare Record, Echo or Cath Imaging Viewing workstation, Cardiology Information System, any simple web application which understands how query the Information Source
• Information Source – ECG Management and Archiving System
