Unless otherwise stated, values are expressed as n (%). aResults expressed as median (25th to 75th percentiles). bOnly 178 patients were admitted to the ICU. c SOFA (1) means SOFA score in the first 24 hours in the hospital. dOnly in 'surgical patients' (n = 93). AAT, appropriate antibiotic therapy; APACHE, Acute Physiology and Chronic Health Evaluation; CI, confidence interval; COPD, chronic obstructive pulmonary disease; ICU, intensive care unit; RR, relative risk; SOFA, Sequential Organ Failure Assessment.
