Imaging Object Change Management

Imaging Object Change Management (IOCM) specifies how one actor communicates local changes applied on existing imaging objects to other actors that manage copies of the modified imaging objects in their own local systems. The supported changes include (1) object rejection due to quality or patient safety reasons, (2) correction of incorrect modality worklist entry selection, and (3) expiration of objects due to data retention requirements. It defines how changes are captured and how to communicate these changes.

The following diagram shows the high level data flow when the immediate recipients (the yellow boxes) of the Rejection Notes also support IOCM.

The following diagram shows the high level data flow when the immediate recipients (the yellow boxes) of the Rejection Notes do not support IOCM but the subsequent consumers do.

Benefits

Provides a simple consistent synchronization mechanism of the following use cases

Data Retention Expiration
Correction or Rejection of imaging instances for Quality Reasons
Correction or Rejection of imaging instances for Patient Safety Reasons
Correction of Modality Worklist Selection

Support progressive enhancement to workflow

The minimal requirement is the introduction of the Change Requester capability into existing Modality, Evidence Creator or Image Manager
Subsequent actors (e.g. Image Display, XDS-I Imaging Document Consumer, etc.) can be upgraded progressively to provide better synchronization

Support intra-enterprise and inter-enterprise workflow

The synchronization mechanism is supported within an enterprise using SWF
The synchronization mechanism is also supported across enterprises using XDS-I or IRWF

The Imaging Object Change Management (IOCM) Integration Profile:

Systems Affected

Systems involved in this profile are:

Enterprise-wide information systems that manage patient registration and services ordering (i.e., admit-discharge-transfer (ADT)/registration system and hospital information system (HIS ))
Radiology departmental information systems that manage department scheduling (i.e., radiology information system (RIS))
Radiology image management/archiving (i.e., picture archiving and communication system (PACS))
Acquisition modalities
