aHospital size categorizes are based on hospital beds and are specific to the hospital’s location and teaching status. Bed size assesses the number of short-term acute beds in a hospital.10

bComorbidities for risk adjustment were derived from Agency for Healthcare Research and Quality (AHRQ) comorbidity measures based on the methods by Elixhauser.13 Diabetes was excluded to avoid multicollinearity.

TPN, total parenteral nutrition; PEG, percutaneous endoscopic gastrostomy; PEJ, percutaneous endoscopic jejunostomy.
