ABSTRACT

Objective: To characterize the erythrocyte distribution width and platelet count in a group of patients admitted to an intensive care unit.
Materials and Methods: Retrospective descriptive observational study. A nonprobabilistic sampling of consecutive cases was performed. Data were analyzed in the Jamovi program using univariate analysis; quantitative variables were analyzed using mean and standard deviation, median and interquartile range, and qualitative variables using absolute and relative frequencies.
Results: Forty-six patients with a median age of 66 years were included, with a male predominance (27 out of 46). The reason for ICU admission was documented in 21 of 46 patients with septic shock. The mean distribution width of erythrocytes was 14.4% before admission to the ICU and 15.4% before death. The median platelet count was 219,000 cells/mm3 before ICU admission and 160,000 cells/mm3 before death. The most common cause of death was cardiorespiratory arrest in 28 of 46 patients.
Conclusions: Biomarkers may be useful as predictors of mortality, according to the results of this study and the literature.
