Study on user interface of pathology picture archiving and communication system

Area of Science:

• Medical Informatics
• Digital Pathology
• Human-Computer Interaction

Background:

• Pathology workflow efficiency is crucial for accurate diagnostics.
• Existing pathology Picture Archiving and Communication Systems (PACS) may lack optimal user experience.
• Improving user interface design can streamline pathology workflows.

Purpose of the Study:

• To conduct a task analysis of the pathology workflow within a pathology PACS.
• To propose a user interface for the pathology PACS that prioritizes user experience.
• To enhance the overall efficiency and usability of digital pathology systems.

Main Methods:

• Performed an interface analysis of the pathology PACS at Seoul National University Hospital.
• Conducted a task analysis of the pathology workflow by observing recorded video data.
• Schematized frequently used menu items based on task analysis findings.

Main Results:

• A hierarchical task analysis of the pathology PACS identified 17 distinct tasks.
• Key tasks included pre-operation, image and text management, and data retrieval.
• Frequently used menu items were identified and visually represented.

Conclusions:

• A user interface for pathology PACS, considering user experience, has been proposed.
• This study serves as a preliminary step towards developing user-centered medical information systems.
• Findings contribute to improving usability and user experience in digital pathology systems.
