Abbreviations: CI, confidence interval; DVT/PE, deep vein thrombosis/pulmonary embolism; MI, myocardial infarction; ICU, intensive care unit; SDU, step-down unit.
a P values represent those associated with the χ2 analyses and Fisher exact tests comparing the nonanticoagulated and anticoagulated cohorts.
b P values represent those associated with the logistic regression model comparing the nonanticoagulated and anticoagulated cohorts (controlled for age, CCI, and anesthesia type).
cTwo patients required evacuation of hematoma.
dZero patients required evacuation of hematoma.
