Abstract

Background: Tracheostomy procedures inhibit swallowing, although details of subsequent recovery of oral intake remain unknown. This retrospective cohort study aimed to investigate factors influencing dysphagia improvement in patients with subacute stroke after tracheostomy.

Methods and results: The study included 117 patients who underwent tracheostomy after subacute stroke, cerebral hemorrhage, or endogenous subarachnoid hemorrhage and received care at 2 convalescent rehabilitation wards in urban and suburban Japan between 2015 and 2022. The primary outcome measure was the achievement of complete oral intake. Patient demographics, Functional Independence Measure scores, body mass index, food intake level scale scores, and the presence of severe white matter hyperintensities on imaging were retrospectively collected from medical records. Statistical analysis involved univariate logistic regression to identify potential predictors and multivariate logistic regression to refine the model while accounting for multicollinearity. In total, 47% of patients achieved complete oral intake on discharge. Sex, days from onset to admission, Functional Independence Measure motor and cognitive scores, body mass index, food intake level scale scores, and severe white matter hyperintensities were identified as potential predictors in the univariate analysis. However, multivariate logistic regression identified only food intake level scale scores (odds ratio [OR], 3.687 [95% CI, 1.519-8.949]; P=0.004) and severe white matter hyperintensities (OR, 0.302 [95% CI, 0.096-0.956]; P=0.042) as significant predictors of complete oral intake.

Conclusions: In patients with subacute stroke undergoing tracheostomy, the level of oral intake on admission and severe white matter hyperintensities on imaging may be better predictors of complete oral intake. However, prospective studies with larger sample sizes and more comprehensive data are warranted to confirm these findings.
