ParcoursVis: Visualization of Patient Pathways


The French Social Security (CNAMTS) wants to analyze the patient pathways for specific treatments to understand how treatments are actually done in contrast to the recommendations. Aviz and CMAP/École Polytechnique are collaborating to design and implement a visualization system, ParcoursVis, to explore its prescription data.

ParcoursVis allow extracting a subset of the nationwide database from CNAMTS, transforming the raw data into meaningful medical events, and visualizing it interactively at scale. It is part of a larger collaboration between École Polytechnique and CNAMTS.
