a
Multivariable logistic regression controlling for clustering at the hospital level.
b
Non–geriatric-specific factors used in regression analysis but without statistically significant findings included age; sex; American Society of Anesthesiologists Physical Status Classification; body mass index; smoking history; corticosteroid use; presence of diabetes, chronic obstructive pulmonary disease, congestive heart failure, ascites, dyspnea, or kidney failure; need for dialysis; and ventilatory dependence.
c
Statistically significant.
