Risk Factors of Nasraway et al for Mortality in a Morbidly Obese Surgical Patient in the Intensive Care Unit (ICU)

 

Patient selection: adult surgical patient with ICU admission >= 4 days

 

Risk factors for increased mortality in the multivariate model:

(1) body mass index (BMI) >= 40 kg per square meter

(2) age >= 55 years, with further increase if >= 70 years

(3) male gender

(4) MPM-24 mortality probability < 70%

 

where:

• Mortality was very high if the BMI was > 60 kg per square meter.

• The fact that mortality was greater for a patient with a lower risk on the MPM-24 may indicate that complications occurred after 24 hours.

 

Additional factors seen on univariate analysis (indicators of organ failure):

(1) renal failure

(2) mechanical ventilation

(3) need for vasopressors
