Red blood cell distribution width to platelet count ratio (RPR) was known as an inflammatory biomarker and was related to poor outcomes of various diseases.Aim: This study was intended to explore the association between RPR and mortality of sepsis patients.Methods: A retrospective cohort study was undertaken in patients with sepsis, and the data were collected from a public database called Medical Information Mart for Intensive Care III (MIMIC-III). The primary outcome was 28-day mortality while the secondary outcomes were 90-day mortality and ICU mortality. Multivariable regression analyses, as well as interaction and stratified analyses, were conducted to investigate the relation between RPR and sepsis mortality.Results: In total, we enrolled 7531 patients with 1316 deaths. RPR was independently correlated with 28-day mortality (per 0.1 increase: HR=1.04; 95% CI 1.02– 1.06), 90-day mortality (per 0.1 increase: HR=1.04; 95% CI 1.03– 1.06) and ICU mortality (per 0.1 increase: OR=1.06; 95% CI 1.02– 1.10). Twenty-eight-day survival was worse in the high RPR (≥ 0.134) group according to the Kaplan–Meier curve analyses (Log rank test, p< 0.001). In stratified analyses, Sequential Organ Failure Assessment (SOFA) score and length of ICU stay had interactive effects with the high RPR (≥ 0.134) group on 28-day mortality.Conclusion: RPR is a novel biomarker that indicates poor prognosis of sepsis patients. Clinicians are required to pay more attention to those patients with high RPR.Keywords: ICU, sepsis, prognosis, inflammatory marker, MIMIC-III |
