Cerebral perfusion pressure and delirium duration

Predictor	Parametric Estimate (95% Confidence Interval)	P Value
Native disease
CF vs. IPF	−0.98 (−2.6 to 0.64)	0.235
COPD vs. IPF	0.32 (−0.79 to 1.44)	0.570
Other vs. IPF	−0.03 (−1.11 to 1.05)	0.950
Postoperative Morbidity Score	−0.72 (−1.48 to 0.04)	0.064
Primary graft dysfunction grade 0/1, 2, or 3 at 72 h	0.65 (0.02–1.28)	0.043
Time in ICU, log transformed, d	0.51 (0.06–0.95)	0.026
Cerebral perfusion pressure, per 10 mm Hg	−0.54 (−1.00 to −0.08)	0.022

Definition of abbreviations: CF = cystic fibrosis; COPD = chronic obstructive pulmonary disease; ICU = intensive care unit; IPF = idiopathic pulmonary fibrosis.

Lower cerebral perfusion pressure was associated with longer duration of delirium after accounting for native disease, postoperative morbidity, primary graft dysfunction grade, and time in the intensive care unit. Parametric estimates were derived from the adjusted model.
