  1. The table shows ICU and hospital stay information, admission information including type of surgery and outcomes for each unit separately. Data are presented as: for binary variables—count (percentage of admissions) and for continuous variables—mean (standard deviation). p values compare control cohort to intervention cohort for each unit. p value calculation is described in ‘Methods’ section. See ‘Results’ section for details
