Implementation of a web-based, interactive polytrauma tutorial in computed tomography for radiology residents: how we...

Area of Science:

• Radiology
• Medical Education
• Health Informatics

Background:

• Polytraumatized patients require rapid diagnosis of CT scans.
• Effective reading schemes are crucial for radiology residents.
• Current training methods may not fully address the speed needed for polytrauma assessment.

Purpose of the Study:

• To develop an online tutorial for structured diagnosis of polytrauma computed tomography (CT).
• To improve the efficiency and accuracy of polytrauma CT interpretation for residents.

Main Methods:

• A didactic concept based on cognitive load theory was employed.
• The ILIAS learning management system was used as the web environment.
• CT datasets were converted into interactive, scrollable movies with guided analyses.

Main Results:

• The tutorial features chapterized content with embedded interactive CT datasets.
• Audiovisual movies demonstrate trauma pathologies and normal scan reading schemes.
• Users can explore common and important pathologies in a self-directed manner.

Conclusions:

• Web-based applications can support ambitious didactic concepts in medical education.
• Cognitive load theory and available software tools facilitate effective online learning for radiology.
