Refining DICOM for pathology--progress from the IHE and DICOM pathology working groups

Area of Science:

• Medical Informatics
• Health Information Systems
• Anatomical Pathology

Background:

• Accurate and accessible medical information is vital for healthcare professionals' decision-making.
• Integrating anatomical pathology data into existing electronic healthcare enterprises presents significant challenges.
• Current systems often lack seamless data flow from pathology departments.

Purpose of the Study:

• To model and standardize the anatomical pathology workflow for better electronic health record integration.
• To develop an integration profile for pathology general workflow within the Integrating the Healthcare Enterprise (IHE) framework.
• To define key information entities and real-world objects within the anatomical pathology domain.

Main Methods:

• Modeling the complete pathology workflow, from order placement to final report generation, including specimen processing and image acquisition.
• Developing an IHE Integration Profile named 'pathology general workflow'.
• Utilizing HL7 and DICOM standards for 8 defined transactions and defining information entities and real-world objects.

Main Results:

• The creation of the 'pathology general workflow' IHE Integration Profile.
• The profile is based on 8 transactions leveraging HL7 and DICOM standards.
• A proposed common model for 'specimen' has been developed through joint efforts with DICOM WG26, supporting both HL7 and DICOM transactions.

Conclusions:

• The developed integration profile and common specimen model facilitate the seamless integration of anatomical pathology information into the electronic healthcare enterprise.
• Standardized workflows and data models improve the availability and correctness of pathology information for medical decision-making.
• Collaboration between IHE and DICOM WG26 has led to a significant advancement in anatomic pathology data interoperability.
