Monitoring and Evaluation
In critically ill medical and surgical ICU patients, what impact does elevated BMI have on mortality?
-
Conclusion
There is conflicting evidence that mortality is increased in critically ill medical and surgical ICU patients with BMI > 25.
-
Grade: II
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.
In critically ill medical and surgical ICU patients, what impact does low BMI have on mortality?-
Conclusion
A BMI < 20 is associated with mortality in critically ill medical and surgical ICU patients.

In critically ill medical and surgical ICU patients, what effect does weight have on infectious complications?-
Conclusion
There is fair evidence that weight status is not associated with increased rate of infection in critically ill medical and surgical ICU patients.

Conclusion
There is fair evidence that LOS is increased in critically ill medical and surgical ICU patients who have a BMI > 30.

In critically ill medical and surgical ICU patients, what effect does weight have on days on mechanical ventilation?-
Conclusion
Most studies suggest that BMI > 30 does not lengthen the number of days on mechanical ventilation in critically ill medical and surgical ICU patients.

In critically ill medical and surgical ICU patients, what effect does weight have on cost of medical care?-
Conclusion
To date, adequately powered studies have not been conducted to demonstrate a significant difference in cost of medical care, when comparing critically ill medical and surgical ICU patients with BMI > 30 to those with BMI < 30.
