Summary
A new visualization and analysis tool (VAT) improves assessment of complex diseases like scleroderma by illustrating patient trajectories and risks. This tool enhances clinical decision-making and patient understanding of their health status.
Area of Science:
- Rheumatology
- Medical Informatics
- Data Visualization
Background:
- Assessing complex disease states, patient trajectories, and risks simultaneously is challenging at the point of care.
- Scleroderma presents a complex case for integrated patient data analysis.
Purpose of the Study:
- To develop and evaluate an interactive data visualization and analysis tool (VAT) for complex diseases.
- To improve the estimation of disease state and individual risk for critical events.
Main Methods:
- Developed a web-based VAT to visualize patient trajectories across multiple organs relative to reference populations and subgroups.
- Embedded internally cross-validated Bayesian multivariate mixed models for real-time risk estimation.
- Conducted usability testing with patients and rheumatologists.
Main Results:
- The VAT aggregates longitudinal data, illustrating patient, subgroup, and population health trajectories.
- Patients reported increased disease knowledge and confidence; rheumatologists accessed more data faster with fewer clicks.
- Statistical models enabled real-time estimation of individual patient risks for multiple complications.
Conclusions:
- Systematic data analysis and visualization of individual and population data can enhance medical decision-making in complex diseases.
- Individualized risk estimation at the point of care may facilitate targeted screening and early intervention for high-risk patients.
