Patient selection: patient admitted to a non-ICU bed from the ED
Early rapid response team activation was defined as within 12 hours of admission.
Parameters:
(1) diagnosis
(2) first respiratory rate in ED in breaths per minute
(3) last respiratory rate in ED in breaths per minute
(4) first oxygen saturation in ED in percent
(5) last oxygen saturation in ED in percent
(6) last heart rate in ED in beats per minute
(7) last systolic blood pressure in ED in mm Hg
