Visualizing and Interpreting Temporal Care Team Dynamics for Cancer Survival Risk Analysis

Read the original on arXiv Machine Learning →

The paper presents a visual analytics framework that models and interprets time‑varying care team interactions in oncology. It builds dynamic collaboration networks from electronic health record communication data and applies a temporal graph neural network to estimate patient risk over time. The system integrates risk modeling with coordinated visualizations, feature‑level explanations, and what‑if analysis to help analysts explore how changes in team composition relate to risk shifts across treatment stages.

GraphBEAT: Graph-based Bucketized Event Aggregation Over Time for Early Risk Stratification of Gastrointestinal Cancers

GraphBEAT is a temporal graph representation learning framework that bucketizes clinical events from longitudinal electronic health records into time‑ordered graphs, enabling early risk stratification for gastrointestinal cancers. It uses a time‑decay message‑passing mechanism and multi‑head attention pooling to generate patient‑level representations, and was trained on multi‑site diagnosis codes and laboratory tests to predict pancreatic, liver, and intestinal cancer at 12, 24, and 36‑month lead times. Across all experiments, GraphBEAT outperformed baseline graph neural networks and sequence models while requiring far fewer floating‑point operations and parameters.
