The clinical significance of changes in red blood cell distribution width in patients with community-acquired pneumonia.

ABSTRACT:

Objective

Red cell distribution width (RDW) is associated with mortality in patients with community-acquired pneumonia (CAP). However, little is known about the effect of changes in RDW during treatment on mortality. Thus, the objective of this study was to evaluate the association between RDW changes and mortality in hospitalized patients with CAP.

Methods

Retrospective analyses were performed using medical records of patients hospitalized for CAP from April 2008 to February 2014. The abstracted laboratory values included RDW (from days one to four), clinical variables, and pneumonia severity index (PSI) scores. The ΔRDW_n-1 was defined as the change in RDW calculated as: (RDW_day1-RDW_day-n)/RDW_day1×100 (%), where 'day n' refers to
