Association of Stroke Impairment Assessment Set and Dysphagia in the 1st Week after Acute Ischemic Stroke with Early Discharge to Home Following Endovascular Therapy: A Retrospective Observational Study.

Abstract

Objective: In this study, we aimed to identify factors associated with the likelihood of early discharge to home by the 7th-day assessment in patients with ischemic stroke who underwent endovascular therapy (EVT).

Methods: Among the 128 patients with ischemic stroke who underwent EVT, 2 groups were identified: an early discharge to the home group and the transfer group, with patients included in the latter group needing to be transferred to rehabilitation hospitals. Variables from the 7th day were used as explanatory variables to determine the outcome. Multiple logistic regression analysis was conducted using these variables. Receiver operating characteristic (ROC) curves for the significant factors were obtained, and cutoff values were calculated.

Results: There were 19 patients (14.8%) in the early discharge to the home group and 109 patients (85.2%) in the transfer group. The Stroke Impairment Assessment Set (SIAS) (odds ratio [OR]: 1.16, 95% confidence interval [CI]: 1.02-1.32, p = 0.03) and the presence of dysphagia (OR: 8.75, 95% CI: 1.55-49.45, p = 0.01) were significant factors associated with early discharge home. The area under the ROC curve of the SIAS was 0.90, with a cutoff value of 63.5 points.

Conclusion: Our results suggest that SIAS scores and the presence of dysphagia within the 1st week post-onset are significant predictors of whether patients with ischemic stroke who undergo EVT can be early discharged home.
