New study shows red blood cell distribution width predicts prognoses in elderly, hospitalized patients

A new study published in the Journal of the American Geriatrics Society found that higher red blood cell distribution width is associated with increased rates of in-hospital mortality and hospital re-admission among older patients. The study included 94,617 patients aged over 60 who were hospitalized between 2013 and 2017.
