  1. APHA acute posthemorrhagic anemia, LOS length of stay
  2. aRecycled prediction method; The following outcome models had questionable fit due to estimated G matrix not positive definite: discharge to non-home; all-cause readmission at 30, 60, and 90 days; transfusion; air leak complications; pneumonia; infection
  3. bDischarge to a non-home setting (e.g., skilled nursing facility, intermediate care facility) vs. discharge to home with or without home healthcare
  4. cIn minutes; n with operating room time data = 156 PVS; 2190 Medtronic manual; operating room time values trimmed to fall between 30 min and 24 h
