Pediatric emergency medicine (PEM) and pediatric critical care (PCC) provide care for all children in all states of distress. The primary distinction between the two is that PEM must be prepared to locate, stabilize, and transfer children in extremis to appropriate care. Therefore, PEM must extend beyond any single or group of institutions and into the regional community. Thus, PEM and PCC have similar and distinct information needs and workflows, many of which are high-risk.
