On the Application of Multi-Class Classification in Physical Therapy Recommendation

  • Selecting appropriate rehabilitation treatments for injured workers has been a challenging task for clinicians and health care funders. Currently, clinicians are unable to identify the optimal treatment for a patient with absolute confidence and are looking for assistance from other research fields, such as Machine Learning. This thesis aims at building a knowledge-based clinical decision support system using machine learning algorithms. We have found that with proper data preprocessing, the RIPPER algorithm can extract meaningful, editable and interpretable decision rules from a severely imbalanced multi-class clinical dataset. Moreover, the extracted rule set is integrated into our prototype Work Assessment Triage Tool (WATT), a web-based online decision support system. It has an easy-to-use interface and provides useful recommendations to help clinicians make better decisions.
