Critical emergency medicine is the medical field concerned with management of critically illpatients in the emergency department (ED). Increased ED stay due to intensive care unit (ICU)overcrowding has a negative impact on patient care and outcome. It has been proposed thatimplementation of critical care services in the ED can negate this effect. Two main CriticalEmergency Medicine models have been proposed, the “resource intensivist” and “ED-ICU”models. The resource intensivist model is based on constant presence of an intensivist in thetraditional ED setting, while the ED-ICU model encompasses the notion of a separate EDbasedunit, with monitoring and therapeutic capabilities similar to those of an ICU. Criticalemergency medicine has the potential to improve patient care and outcome; however, establishmentof evidence-based protocols and a multidisciplinary approach in patient managementare of major importance.
