Patient physiological status during emergency care and rapid response team or cardiac arrest team activation during early hospital admission

Objectives: The objective of this study was to examine the relationship between rapid response team (RRT) or cardiac arrest team (CAT) activation within 72 h of emergency admission and (i) physiological status in the emergency department (ED) and (ii) risk for ICU admission and in-hospital mortality. Methods: A retrospective matched cohort study was conducted in three hospitals in Melbourne, Australia. The exposed cohort (n=660) included randomly selected adults admitted to the medical or surgical ward through the ED who had RRT or CAT activation within 72 h of admission. Unexposed matched controls (n=1320) did not have RRT or CAT activation. Results: The exposed cohort was more likely to have physiological abnormalities fulfilling hospital RRT activation criteria during ED care (36.7 vs. 23.8%, P
