ACC – aggregate condition codes; Sepsis – community or healthcare-associated sepsis, excluding CLABSI; Pneumonia – community or healthcare-associated pneumonia, excluding VAP; CLABSI – central-line associated blood stream infection; VAP – ventilator associated pneumonia; Comparison between the control group and an infection group: * p < 0.05; **p < 0.01; Overall test between all groups: †p < 0.05; ††p < 0.01.
