Red Cell Distribution Width (RDW) as a Prognostic Marker in ICU

The aim of this study is to verify if high values of RDW are useful prognostic marker for ICU mortality and 90-days mortality. Moreover, we will investigate the prognostic value of RDW in specific subgroup population with some clinical characteristic wich may modify RDW baseline values, i.e. transfused patients or patients with high markers of hemolysis
