Relationship between Driving Pressure and Mortality in Ventilated Patients with Heart Failure: A Cohort Study

Table 2

Multivariable logistic regression analyses of driving pressure and in-hospital mortality.

Variable	Crude model, n = 632	P value	Minimally adjusted model, n = 632	P value	Fully adjusted model, n = 603	P value
Driving pressure (cmH2O)	1.07 (1.02, 1.11)	0.0022	1.09 (1.04, 1.14)	0.0002	1.12 (1.06, 1.18)	<0.001
Driving pressure tertials
Low	Reference		Reference		Reference
Mid	0.72 (0.46, 1.12)	0.1430	0.71 (0.45, 1.12)	0.1376	0.74 (0.44, 1.23)	0.242
High	1.65 (1.09, 2.49)	0.0174	1.89 (1.23, 2.90)	0.0039	2.26 (1.36, 3.77)	0.002
P for trend	0.009	0.0019	0.002

Crude model: no other covariates were adjusted. Minimally adjusted model: we adjusted age and sex. Fully adjusted model: we adjusted age, sex, BMI, heart rate, MAP, WBC, hemoglobin, creatinine, CVP, NT-proBNP, PEEP, PH, PaO₂, PaCO₂, PF ratio, ventilation mode (CMV), VT/PBW, Elixhauser score, SOFA score, and SAPS score.
