  1. Team arrival time was defined as the first documented arrival time of a designated resuscitation team member at each hospital. First-responder CPR was defined as immediate commencement of CPR within 1 min of documented cardiac arrest. Immediate resuscitation team arrival was defined as arrival of the resuscitation team within 1 min of documented cardiac arrest. Median time to commencement of CPR was not calculated because > 50% of the documented times to CPR was less than 1 min. aMissing data: 8 for arrival time of resuscitation team, 1 for witnessed arrest, 15 for shockable rhythm, 3 for ROSC.
