Introduction: Red Blood Cell Distribution (RDW) consists in an index used to determine heterogeneity for red blood cells, which measures anemia or malnutrition disorders. However, its statistical elevation was associated with other inflammation biomarkers. Values above 15% are associated with increased mortality rate in critically ill patients. 

Objective: To determine the RDW increase and mortality ratio, in this environment, for patients in the Intensive Therapy Unit. 

Methodology: Control group consisted of hospitalized patients between March 2018 and August 2018, and the following data was included in the statistical analysis: SOFA, SAPS 3, hemoglobin, hematocrit, leucocytes, platelets, RDW, creatinine, albumin, as well as demographic data. The values assessed by the laboratory team in this unit were considered to be within normal levels. 

Results: Regarding the Chi-squared distribution statistical test, a p value of 0.048 was obtained when linking the number of deaths in the ITU to the RDW values, which proves the relationship between these variables. 

Conclusion: The RDW increase is highly associated with a higher mortality rate and is useful for risk stratification in critically ill patients.
