SummaryRed cell distribution width (RDW) has been shown to be an independent predictor of mortality in patients with coronary artery disease and in patients with heart failure. The current study evaluated the prognostic utility of RDW in patients undergoing percutaneous coronary intervention (PCI). We evaluated 859 patients who underwent PCI during January 2003 to August 2005. After a median follow up of four (interquartile range 3.1 to 4.4) years, there were a total of 95 (11%) deaths. RDW was analysed as a categorical variable with empirically determined cut points of 13.3 and 15.7 (low RDW <13.3, medium RDW ≥13.3 to <15.7, high RDW ≥15.7) based on differences in hazard ratio (HR) for death among RDW deciles.In univariate analysis, higher RDW was a significant predictor of mortality (p<0.001). In multivariate analysis there was a significant two-way interaction between RDW and haemoglobin (Hgb). RDW was not an independent predictor of mortality in patients with Hgb <10.4. However, among patients with Hgb >10.4, high RDW was a strong and independent predictor of mortality. For patients with Hgb ≥10.4 to <12.7, HR for death in patients with high RDW relative to low RDW was 5.2 (95% confidence intervals [CI]: 2.0–13.3). For patients with Hgb ≥12.7, HR for death in patients with high RDW relative to low RDW was 8.6 (CI:2.8–28.6). Higher RDW was a strong and independent predictor of long-term mortality in patients undergoing PCI who were not anaemic at baseline.

Background. Elevated red cell distribution width (RDW) has been reported to be associated with mortality in some critically ill patient populations. The aim of this article is to investigate the relationship between RDW and in-hospital mortality and short- and long-term mortality of patients with cholecystitis. Method. We conducted a retrospective cohort study in which data from all 702 patients extracted from the Medical Information Mart for Intensive Care III (MIMIC-III) database were used. Receiver operating characteristic (ROC) curves were constructed to evaluate the prognostic predictive value of RDW for in-hospital mortality and short- (i.e., 30-day and 90-day) and long-term (i.e., 180-day, 1-year, 3-year, and 5-year) mortality. We converted RDW into a categorical variable according to quintiles as less than or equal to 13.9%, 14.0-14.8%, 14.9-15.8%, and 15.9-17.2% and more than 17.2%. The Kaplan-Meier (K-M) methods and log-rank tests were used to compare survival differences among different groups. The relationships between RDW levels and in-hospital mortality were evaluated by univariate and multivariate binary logistic regression models. Multivariable Cox regression models were built to investigate the association of RDW on the short-term and long-term mortality. Result. After adjusting for potential confounders, RDW was positively associated with in-hospital mortality (OR: 1.187, 95% CI [1.049, 1.343]) and short- (i.e., 30-day: HR: 1.183, 95% CI [1.080, 1.295], 90-day: HR: 1.175, 95% CI [1.089, 1.268]) and long-term (i.e., 1-year: HR:1.162, 95% CI [1.089, 1.240]) mortality in critically ill patients with cholecystitis. Similar results were also shown in the secondary outcomes of 180-day, 3-year, and 5-year mortality. RDW had a significant accurate prognostic effect on different endpoints and could improve the prognostic effect of scoring systems. Conclusion. High level of RDW is associated with an increased risk of in-hospital mortality and short- and long-term mortality in critically ill patients with cholecystitis. RDW can independently predict the prognosis of patients with cholecystitis.
