This study shows that both novice and expert clinicians prefer rule-tracing explanations from a Wound Clinical Decision Support System (CDSS) app. Novices prefer detailed explanations, while experts prefer concise summaries for wound management.
Area of Science:
- * Digital Health and Clinical Decision Support Systems (CDSS)
- * Medical Informatics and Artificial Intelligence in Healthcare
- * Wound Management and Clinical Practice
Background:
- * Clinical Decision Support Systems (CDSS) require reliable explanations for user adoption, particularly in complex areas like wound management.
- * Novice clinicians often experience decision uncertainties in wound care despite available guidelines.
- * Existing literature suggests rule-tracing explanations are primarily beneficial for novices.
Purpose of the Study:
- * To evaluate a Wound CDSS smartphone application providing rule-tracing explanations for its recommendations.
- * To investigate the preference for different forms of rule-tracing explanations (verbose-based vs. gist-based) among clinicians with varying expertise levels.
- * To test the hypothesis that both novice and expert clinicians prefer rule-tracing explanations, but in different formats.
Main Methods:
- * Development and utilization of a Wound CDSS smartphone app that analyzes wound images captured by clinicians.
- * Experimentation with two types of rule-tracing explanations: verbose-based (detailed) and gist-based (concise).
- * Comparative evaluation of clinician preferences for these explanation types based on decision-making theories.
Main Results:
- * The study hypothesizes that both novice and expert clinicians will prefer rule-tracing explanations.
- * Novice clinicians are expected to prefer verbose-based explanations for greater detail.
- * Expert clinicians are expected to prefer gist-based explanations for efficiency and conciseness.
Conclusions:
- * Rule-tracing explanations are valuable for wound management CDSS adoption across different expertise levels.
- * Tailoring explanation formats (verbose for novices, gist for experts) can enhance CDSS usability and effectiveness.
- * This approach addresses decision uncertainties faced by clinicians in wound care settings.
