A mean Acute Physiology, Age, and Chronic Health Evaluation (APACHE III) score of >50 is associated with increased intensive care unit mortality rate in nonpregnant cardiac and trauma patients.
As noted previously, postoperative delirium is associated with increased intensive care and hospital stay, with persistent cognitive decline and with increased mortality.
It has known risk factors and is associated with increased intensive care and hospital lengths of stay, increased mortality, and long-term cognitive impairment [ 2, 3].
In non-pneumococcal severe community-acquired pneumonia, early antibiotic administration and use of combined antibiotic therapy were both associated with increased intensive care unit survival during the study period.
See related research by Lee et al., Extubation failure (the need for re-intubation) is associated with increased intensive care unit and hospital mortality, increased length of stay in the intensive care unit and hospital, greater need for tracheostomy and for long-term acute care, and increased costs.
Unfortunately, NIV did not improve outcome for established postextubation respiratory failure [ 6] and was actually associated with increased intensive care unit (ICU) mortality when used in a large cohort with early signs of extubation failure (only 10% of whom had chronic obstructive pulmonary disease) [ 7].
Among the respiratory variables considered only the PaCO2 was associated with an increased intensive care mortality (OR 1.08, 95% confidence interval 1.021 1.152).
Mechanically ventilated patients are at risk for ventilator-associated pneumonia (VAP) [ 1], which is associated with an increased intensive care unit (ICU) length of stay (LOS), morbidity and mortality [ 2– 5].
Elevated preoperative NLR is also associated with increased morbidity postoperatively, with prolonged hospitalization and increased intensive care admission.
Although resuscitation strategies for severely injured patients who present with shock have improved greatly, these transfusions are associated with development of MOF, and increased intensive care unit (ICU) admissions, ICU and hospital length of stay, and mortality [ 18- 21].
