Abstract:
Objective To investigate the correlation between 28-day prognosis and red cell distribution width (RDW) in sepsis patients.Methods This was a prospective observational study.Two hundred and thirteen sepsis patients were consecutively selected,and the patients were divided into 2 groups according to RDW:normal RDW group (RDW ＜ 0.15,160 cases) and high RDW group (RDW≥0.15,53 cases).The general conditions,acute physiology and chronic health evaluation (APACHE) 1Ⅱ score,sequential organ failure assessment (SOFA),hypersensitive C reactive protein (hs-CRP),procalcitonin (PCT),arterial blood lactic acid,liver function injury,renal function injury and 28-day mortality were compared between 2 groups.The independent risk factors of 28-day prognosis were analyzed by multifactor Logistic regression analysis.Kaplan-Meier survival analysis was used to draw the 28-day survival curve,and the survival rate was compared between 2 groups by log-rank test.Results The 28-day mortality in high RDW group (35.8％,19/53) was significantly higher than that in normal RDW group (17.5％,28/160),and there was statistical difference (P =0.007).RDW ≥0.15 was the independent risk factor of 28-day death in sepsis patients (OR =2.634,95％ CI 1.316-5.273,P =0.006).After adjusted by gender,age and other relative factors,RDW≥0.15 was the independent risk factor of 28-day death in sepsis patients (OR =2.895,95％ CI 1.155-7.252,P =0.023).The 28-day accumulative survival rate in high RDW group was significantly lower than that in normal RDW group (50.5％ vs.63.0％),and there was statistical difference (P =0.014).Conclusion The high RDW in sepsis patients is the independent risk factor of 28-day death,and RDW ≥0.15 shows an important predictive value in the prognosis of sepsis patients.
