Background: Infection is the leading cause of multiple organ dysfunction syndrome (MODS) in the elderly. Red blood cell distribution width (RDW) was considered to be associated with many diseases. We aimed to explore whether RDW was associated with MODS in elderly infected patients.
Methods: We retrospectively collected data from elderly patients (≥ 65 years old) with infection. In this study, we conducted a 1:3 case-control match based on age and gender and utilized binary Logistic regression to investigate the impact of variables such as RDW on MODS.
Results: A total of 576 eligible patients were included in this study. RDW in the case group was significantly higher than that in control group (p < 0.001). Multivariate analysis found that RDW was an independent risk factor for MODS in elderly infected patients (OR = 1.397, 95% CI: 1.166-1.674, p < 0.001).
Conclusions: RDW was an independent risk factor for MODS in elderly patients with infection.
