This retrospective study reveals the correlation between RDW changes and mortality in ICU patients, suggesting its potential as a monitoring marker.

The research aimed to analyze the relationship between RDW levels and mortality in ICU patients.
Retrospective analysis of 776 ICU patients admitted from January to December 2013.
Evaluated RDW levels at ICU admission and discharge along with mortality rates.
Utilized statistical tests like Kolmogorov Smirnov, t-test, Mann Whitney U test, and Chi-square for data analysis.
The study reported a mortality rate of 38.2% among the 776 patients.
Deceased patients had increasing RDW levels, while survivors showed decreasing levels (p < 0.05).
Significant correlation was found between RDW increments and length of hospital stay in those who died (p < 0.05).

Turan et al. (2016) studied this question.
