Association of mean <scp>RDW</scp> values and changes in <scp>RDW</scp> with in‐hospital mortality in ventilator‐associated pneumonia (<scp>VAP)</scp>: Evidence from <scp>MIMIC‐IV</scp> database

Abstract

Higher mean RDW values were significantly associated with an increased risk of in-hospital mortality in VAP. Additionally, a linear relationship was found between delta RDW values and in-hospital mortality. These findings suggest that RDW can be used to identify high-risk patients with poorer outcomes in VAP.
