Objectives: This study aimed to examine the association between the Controlling Nutritional Status (CONUT) score at admission and in-hospital mortality among patients admitted to a specialized ward for individuals with severe disabilities. Methods: This retrospective cohort study included 118 hospitalized patients with severe disabilities. The participants were classified into survival and mortality groups. Logistic regression analysis was performed to identify the factors associated with mortality. The optimal cut-off value was determined using receiver operating characteristic (ROC) curve analysis. Survival was evaluated using the Kaplan–Meier method and compared using the log-rank test. Cox proportional hazards regression analysis was conducted to assess the mortality risk. Results: The mortality group had significantly higher CONUT scores than the survival group (p <0.01). Multivariable logistic regression analysis showed that the CONUT score was associated with mortality (odds ratio 1.32, 95% confidence interval [CI] 1.11–1.57, p <0.01). The ROC analysis identified an optimal cutoff value of 4 (≤4 vs. >4). Multivariable Cox proportional hazards analysis also demonstrated that the CONUT score was associated with mortality (hazard ratio 1.20, 95% CI 1.08–1.32, p <0.01). Conclusions: The CONUT score at admission was associated with in-hospital mortality in a population of patients with severe disabilities. Higher scores were associated with increased mortality risk.
