Update Hierarchy 363680008|Radiographic imaging Procedure (procedure)|and Descendants

A Briefing Note documenting the proposed changes for the hierarchy 363680008|Radiographic imaging procedure (procedure)| and descendants was shared with the Editorial Advisory Group, Clinical Leads Group, Member Forum, Content Managers Advisory Group, and other key stakeholders in July 2023.

Feedback was received from a wide range of stakeholders. In response to this feedback, the proposed changes to the hierarchy have been modified. These modifications will address issues raised in the feedback.

This Informational Briefing Note summarizes the changes that will be implemented.

Implementation of the content changes will commence in Q4 2023. The updates will be implemented in sub-hierarchies and promoted over a number of international monthly releases until complete.

Inactivation of Complication Disorder Concepts (371 concepts)

The inactivation of concepts that reference “complication” without specifying the nature of the complication is planned. 

The primitive “Complication (disorder)” grouper was inactivated in 2022 due to a lack of consistency or definition of what would properly be assigned as a subtype.

The concepts will be inactivated with inactivation reason “Classification derived concept” and replacement by the parent concept. 

For further information please see this briefing note. 

Angioplasty procedures

In response to several enquiries from members about the apparent duplication of concepts and descriptions for procedures representing 'Percutaneous transluminal angioplasty' an analysis of the content in this area is underway. It is expected to result in inactivation of duplicates, updates to the descriptions of published concepts and remodeling to represent the imaging guidance aspect where appropriate.

After the analysis of the impact has been completed, a Briefing Note will be dispatched to provide details of the changes. Examples of potential duplication:

• 3261007| Angioplasty of subclavian artery (procedure)
• 418738003 | Fluoroscopic angioplasty of subclavian artery (procedure)
• 175454003| Percutaneous angioplasty of subclavian artery (procedure)
• 431485005 Percutaneous transluminal angioplasty of subclavian artery using fluoroscopic guidance (procedure) - correct term.
  

Review 1263452006 |Anesthesia and/or sedation procedure (procedure)|

A review of the 1263452006 |Anesthesia and/or sedation procedure (procedure)| hierarchy is in progress, the focus is on:

• Inactivation of Classification derived components.
• Review of the current model and possible addition of 363703001 |Has intent (attribute)| to the model.
• Review of current classification of groupers.

Review 48537004 |Bypass graft (procedure)| 

A review of the 48537004 |Bypass graft (procedure)| hierarchy is in progress, the focus is on:

• Improving consistency of descriptions.
• Improving definitions for different types of concepts in the hierarchy (bypass vs shunt)
• Correct use of the term “graft” within the descriptions.
• Correct modeling of 260686004 |Method (attribute)| in the hierarchy.
• Review of the need for 360021005 |Bypass - action (qualifier value)| and 424208002 |Shunt - action (qualifier value)|in the model and testing of 245854003 |Proximal anastomosis (qualifier value)| and 245855002 |Distal anastomosis (qualifier value)| as new 260686004 |Method (attribute)| values in the hierarchy.
• Review for a consistent and appropriate usage of 425362007 |Surgical insertion - action (qualifier value)|and 129407005 |Grafting - action (qualifier value) in the model.
• Review for re-classification of 129376004 |Construction - action (qualifier value)| as a direct subtype of 129284003 |Surgical action (qualifier value)|.
• Given the complexity of some concepts in the hierarchy, potential duplicate, erroneous, or outdated concepts will be identified.

Review Use of 424876005 |Surgical approach (attribute)| 

A review to generalize 424876005 |Surgical approach (attribute)| to allow non-surgical procedures to be modeled with a subtype of <<103379005 |Procedural approach (qualifier value)| is in progress. 

• This issue is under review by the Editorial Advisory Group.
• Currently, 424876005 |Surgical approach (attribute)| is restricted to subtypes of 387713003 |Surgical procedure (procedure)|.  However, the values represented by the 103379005 |Procedural approach (qualifier value)| subhierarchy are applicable to concepts that are not subtypes of Surgical procedure and could potentially be used to define "non-surgical" procedure concepts.
• The impact of MRCM rule for using 116688005 |Procedure approach (attribute)| with domain constraint:  << 71388002 |Procedure (procedure)| and range constraint:  << 103379005 |Procedural approach (qualifier value) is under review. This change would allow Non-surgical procedures to be modeled with a generic Procedure approach attribute.

Review 1287742003 |Radiotherapy (procedure)| 

A review of 1287742003 |Radiotherapy (procedure)| hierarchy is in progress, the focus is on:

• Review of the devices and systems used in the hierarchy for update and to correct subsumption.
• Radiotherapy procedures will be modeled with 260686004 |Method (attribute)| = 129445006 |Administration - action (qualifier value)| and 424244007 |Using energy (attribute)| =  125576007 |Ionizing radiation (physical force)|.
• Changes in the model for the associated subhierarchies: 152198000 |Brachytherapy (procedure)|, 33195004 |External beam radiation therapy procedure (procedure)|, 169331000 |Combined radiotherapy (procedure)| and 399315003 |Radionuclide therapy (procedure)| for correct subsumption.
• Inactivation of 257863009 |Radioactive destruction (qualifier value)| and Brachytherapy - action (qualifier value).

Review 424226004 |Using device (attribute)| vs. 363699004 |Direct device (attribute)| for Modeling of Repair Procedures

424226004 |Using device (attribute)| and 363699004 |Direct device (attribute)| are used interchangeably for modeling of repair procedures within the Repair group of relationships.

• 363699004 |Direct device (attribute)| should be used when grouped with 260686004 |Method (attribute)| = << 257903006 |Repair - action (qualifier value)|.
• Exceptions were found where the device is used to perform the procedures but are not involved directly in the Repair action itself. e.g. 82830000 |Robotic arm, device (physical object)|
• New model is being tested.
