*APACHE II, Acute Physiology and Chronic Health Evaluation II, is an ICU severity of illness scoring system ranging from 0 to 71, with higher scores corresponding to more severe disease; ^†Charlson Comorbidity Index is a prognostic tool that has been validated in critically ill patients, with higher scores indicating worse prognosis [37]. IQR, interquartile range; ICU, intensive care unit; SICU, surgical/trauma ICU; TICU, thoracic ICU; CCU, cardiac care unit; MICU, medical ICU.
