Definition of abbreviations: CI = confidence interval; IQR = interquartile range; LOS = length of stay.
Risk-adjusted hospital mortality is based on chi-square test of trend, and hospital LOS is based on the nonparametric equality-of-medians test.
The quartiles of probability of bundle compliance are based on two individual unadjusted random-effects logistic regression models where hospital is the random term. Only patients with a sepsis protocol initiated were included in the model (n = 72,293).
