Abstract 【Objective】To investigate the correlation between the distribution of red cell distribution width and the prognosis of the severe pneumonia of the elderly patients.【Methods】We performed a retrospective analysis of 74 elderly patients with severe pneumonia in our hospital from June 2013 to December 2015. According to the survival of discharge, the patients were divided into the survival group and death group. The records included gender, age, acute physiology and chronic heath evaluationⅡ (APACHE Ⅱ) score, WBC, HCT, MCV, Hb, PLT and PDW. RDW on day 1, 3, and 7 were collected as well. Multivariate regression analysis of clinical prognostic factors was conducted.【Results】The mean RDW of d₁, d₃and d₇in the death group increased gradually, however, the mean value of RDW of d₁, d₃and d₇did not show a linear trend in the survival group. Multivariate regression analysis showed that age, APACHE II score, RDW and progressive elevation of RDW were the independent risk factors of severe pneumonia in the elderly patients (P＜0.05).【Conclusion】RDW was the independent risk factors for the mortality of severe pneumonia in the elderly patients, and the progressive increase of RDW suggests a poor prognosis.
