The intensive care unit patient is susceptible to a number of common healthcare-acquired infections, including ventilator-associated pneumonia (VAP), catheter-related bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), and Clostridium difficile infections (CDIs), among others. There are numerous predisposing factors to take into consideration, say Dhillon, et al., who add, "Critically ill patients in the ICU are more likely to have invasive catheters, devices, or undergo surgical treatments that disrupt the skin barrier. Burn victims also develop HAIs as a result of the physical barrier disruption. The ability to clear infections may further be reduced by an underlying chronic diseases, thus increasing the risk of HAI. Other significant risk factors include urinary catheter >10 days, ICU confinement >3 days, presence of intracranial pressure monitor/arterial line/central venous catheter, and shock."
