Multi-modal pediatric critical care datamart for extracorporeal support prediction and decision support

To develop a multimodal pediatric critical care datamart supporting predictive modeling and decision support tool development, integrating high-resolution physiologic and clinical data and future clinical deployment.

We developed a continuously expanding datamart integrating electronic health record data, high-resolution telemetry, and extracorporeal membrane oxygenation (ECMO)-domain datasets. The platform links static and longitudinal time-series variables with expert-curated neurologic outcomes for both ECMO and non-ECMO patients, enabling trajectory-based analyses.

The datamart currently includes 25 762 pediatric patients, of whom 395 received ECMO support. The datamart captures granular longitudinal physiologic, laboratory, medication, and telemetry data suitable for dynamic predictive modeling.

Existing ECMO prognostication tools rely on static variables and lack appropriate control cohorts. This datamart enables trajectory-based multimodal modeling, that reflects evolving physiology and neurologic outcomes.

This platform provides a scalable foundation for predictive modeling across pediatric critical care, beyond ECMO, to support precision decision-making and outcomes research.
