Severity-of-illness markers as predictors of nosocomial infection in adult intensive care unit patients.
Patients admitted to intensive care units (ICUs) are at high risk for acquiring nosocomial infections. We examined the association between markers of severity of illness at ICU admission and the development of ICU-attributable nosocomial infections. ⋯ The need for mechanical ventilation on ICU day 1 and transfer to the ICU from another unit are independent predictors of ICU-attributable nosocomial infections. Up to 50% of ICU patients who develop nosocomial infections could be easily identified at ICU admission, allowing for targeted use of preventive strategies to reduce the risk of nosocomial infections.
