Primary outcomes across groups were inpatient mortality and VTE events. VTE events were defined as either PE (415.1x, I26x, I26.90, I26.92, and I26.99) or DVT (453.4x, 453.8, I82.4x, and I82.5x) diagnosed during hospital admission and not part of the patient's past medical history. Secondary outcomes included complication rates (pneumonia, urinary tract infection [UTI], arrhythmias, sepsis, reintubation, wound infection, cardiac arrest, coagulopathy, acute respiratory distress syndrome, hospital length of stay [hLOS], intensive care unit [ICU], length of stay [LOS], and ventilator days).
