Statistics are median and IQR (25th–75th) percentile unless stated otherwise.
Data are based on up to 30 episodes (with a non-elective procedure) randomly selected per area per month.
*Some patients had more than one admission, hence there were more episodes than number of patients.
†Captured in the 12-hour pre-procedural time frame.
