New tools for learning and transferring information…..
What has been the clinical impact?
Estimated <0.1% in routine clinical use
Business Intelligence: Improve operational & safety-related decision support
• Monitoring of key quality & performance indicators
Precise population-based care:
• Data-driven clinical care and management throughout the patient journey
Individualized patient care:
• Diagnosis, trajectory and prognosis, & decision support

Signal processing…….
More subtle phenomena……
• “Hidden variables”- things not easily measured directly at bedside (variability measures, SVR, oxygenation parameters, autoregulation)
Hering-Traube Mayer waves
We need……• Multi-modal and multi-site Physiologic Databank
• Data management platform:
- 4R’s: relational, reliable, robust and retrievable (beyond the 4 V’s)
• Linkages established with categorical registries and other sources of data
• APIs written => Distributive computing ready
• Governance structure, shared, open source (democratized)
• Knowledge translation and implementation
Pediatric cardiac critical care well placed to realize this
