Simplified Adult Echocardiography Templates 

The templates that comprise the Simplified Adult Echocardiography Report are interconnected as in Figure A-10b.

TID 5300 Simplified Echo Procedure Report

This template forms the top of a content tree that allows an ultrasound device to describe the results of an adult echocardiography imaging procedure.

The template is instantiated at the root node. It can also be included in other templates that need to incorporate echocardiography findings into another report as quoted evidence.

This template does not include an Image Library. Image Content Items in the Echo Measurement templates (for example to indicate Source of Measurement) shall be included with by-value relationships, not with by-reference relationships.

Measurements in this template (except for the Wall Motion Analysis) are collected into one of three containers, each with a specific sub-template and constraints appropriate to the purpose of the container.

  • Pre-coordinated Measurements

    • Are fully standardized measurements (many taken from the ASE practice guidelines).

    • Each has a single pre-coordinated standard code that fully captures the semantics of the measurement.

    • The only modifiers permitted are to indicate coordinates where the measurement was taken, provide a brief display label, and indicate which of a set of repeated measurements is the preferred value. Other modifiers are not permitted.

  • Post-coordinated Measurements

    • Are non-standardized measurements that are performed with enough regularity to merit the control and configuration to capture the full semantics of the measurement. For example these measurements may include those configured on the cart by the vendor or user site. Some of these may be variants of the Pre-coordinated Measurements.

    • A set of mandatory and conditional modifiers with controlled vocabularies capture the essential semantics in a uniform way.

    • A single pre-coordinated code is also provided so that when the same type of measurement is encountered in the future, it is not necessary to parse and evaluate the full constellation of modifer values. Since this measurement has not been fully standardized, the pre-coordinated code may use a private coding scheme (e.g., from the vendor or user site).

  • Adhoc Measurements

    • Are non-standardized measurements that do not merit the effort to track or configure all the details necessary to populate the set of modifiers required for a post-coordinated measurement.

    • The measurement code describes the elementary property measured.

    • Modifiers provide a brief display label and indicate coordinates where the measurement was taken. Other modifiers are not permitted.

For an example of this encoding and a discussion of the benefits and use cases, see Annex CCCC Populating The Simplified Echo Procedure Report Template (Informative) in PS3.17.

Content Item Descriptions

Row 8

A text string containing one or more sentences describing one or more indications, possibly with additional comments from the physician or tech.

Row 11

These are measurements from a standardized list of pre-coordinated codes. See CID 12300 “Core Echo Measurements”. Measurements which do not correspond to the full semantics of one of the pre-coordinated codes in CID 12300 can likely be encoded in Row 13 instead.

Multiple instances of the same measurement code may be present in the container. Each instance represents a different sample or derivation.

This template makes no requirement that any or all samples be sent. For example, a mean value of all the samples of a given measurement could be sent without sending all or any of the samples from which the mean was calculated. Device configuration and/or operator interactions determine what measurements are sent.

Row 13

These are measurements that can be encoded using a standardized structure of post-coordinated codes. Measurements which correspond to the full semantics of one of the pre-coordinated codes in CID 12300 “Core Echo Measurements” should be encoded in Row 11 instead.

$Measurement shall be provided, but is not constrained to a CID.

Multiple instances of the same measurement code may be present in the container. Each instance represents a different sample or derivation.

This template makes no requirement that any or all samples be sent. For example, a mean value of all the samples of a given measurement could be sent without sending all or any of the samples from which the mean was calculated. Device configuration and/or operator interactions determine what measurements are sent.

Row 15

These are adhoc measurements encoded with minimal semantics.

Row 13 can be used to encode measurements with more complete semantics.

$Units shall be provided, but is not constrained to a CID.

Device configuration and/or operator interactions determine what measurements are sent.

Rows 17-24

When present, these rows contain measurements and associate them with a specific stage of a staged procedure.
