Description:
Falls are the leading cause of injuries among older adults, particularly in the more vulnerable home health care (HHC) population. Existing standardized fall risk assessments often require supplemental data collection and tend to have low specificity. We curated a home health care assessment dataset with over 100 clinical, behavioral, and cognitive features and applied a random forest algorithm to identify factors that predict and quantify fall risks. We will extend the analysis to incorporate longitudinal assessments and apply natural language processing techniques on visit notes to identify fall cases unreported in structured data. Our model achieves higher precision and balanced accuracy than the commonly used multifactorial Missouri Alliance for Home Care fall risk assessment. This could lead to a reduction of paperwork for nursing staff and better targeting of high fall risk patients.
