Eosinophil count at intensive care unit admission was not predictor of hospital mortality: results of a case control study.

Background: Predicting mortality in the intensive care unit (ICU) is one of the biggest challenges in critical care medicine. Several studies have linked the presence of eosinopenia with adverse outcomes in different populations.

Methods: We performed a case control study to determine whether the eosinophil count at ICU admission was a predictor of hospital mortality.
