Trajectories and populationsMedium- to long-term vision

From individual memory to collective knowledge.

Cohorts, trajectory comparison and population analysis from an enriched clinical memory.

Observe

Individual stories. Populations to explore.

Build cohorts from clinical and temporal criteria and, where available and authorized, social criteria.

Compare

Similar patients. Sometimes different pathways.

Compare trajectories by events, treatments and conditions, to spot similar pathways and understand what sets them apart.

Measure

From individual pathways to collective indicators.

Analyze volumes, events, time intervals, trends and other indicators defined by the organization.

Primary use, secondary use: boundaries to respect

A memory built for care does not automatically become a freely usable secondary data warehouse. Research and operational management uses require defined purposes, appropriate data, governance rules and, in some cases, separate authorizations.

The EHDS phases in new obligations and opportunities for primary and secondary use from 2029, and from 2031 for further data categories.

Key takeaways

From individual stories to collective insight.

  1. Build cohorts

    From clinical and time-based criteria and, where authorized, social ones.

  2. Compare trajectories

    Spot similar pathways and understand what sets them apart.

  3. Measure and steer

    Volumes, delays, trends: indicators defined by your organization.

A step-by-step approach

Start with a clinical question. Broaden the perspective step by step.

Comparison and management capabilities are rolled out as they are validated and productized.
