Development of a Video Coding Scheme for Understanding Human-Computer Interaction and Clinical Decision Making

Area of Science:

• Health Informatics
• Human-Computer Interaction
• Cognitive Science

Background:

• Usability of healthcare information technology (HIT) is a significant challenge in health informatics.
• Numerous studies report unusable HIT systems, impacting clinicians and patient care.
• Effective analysis of usability study data is crucial for optimizing HIT systems.

Purpose of the Study:

• To develop and organize a principled video coding scheme for analyzing HIT usability.
• To integrate human-computer interaction (HCI) categories with human cognition assessment.
• To evaluate the impact of HIT on clinical reasoning and decision-making.

Main Methods:

• Developed a video coding scheme based on prior work in HCI and cognitive science.
• Incorporated categories for analyzing human-computer interaction issues.
• Integrated categories for characterizing human cognition, including clinical reasoning.
• Applied the scheme to assess technology's effect on clinical decision-making.

Main Results:

• A novel, integrated video coding scheme was successfully developed.
• The scheme allows for simultaneous evaluation of usability and cognitive factors.
• The methodology provides a framework for understanding technology's impact on clinical workflows.

Conclusions:

• The developed coding scheme offers a comprehensive approach to analyzing HIT usability.
• This method can lead to the design of more efficient and user-centered healthcare systems.
• Further research can refine this approach for broader application in health informatics.
