Abstract:
Objective:To identify factors associated with swallowing recovery in patients with dysphagia after ischemic stroke.
Methods:Patients admitted to Kangbuk Samsung Hospital from 2011 to 2019 for first acute ischemic stroke and dysphagia, as confirmed by a videofluoroscopic swallowing study (VFSS), were enrolled in this retrospective study. Patients whose Dysphagia Outcome and Severity Scale (DOSS) level was ＜6 as determined by VFSS were monitored in a dysphagia clinic and additional VFSS was performed periodically until one year after stroke. Follow-up was discontinued when the DOSS level reached 6 or 7. The main study outcomes were full recovery and tube removal rate. Cox regression analysis was used to identify prognostic factors of dysphagia. The Kaplan-Meier method was used to generate curves of the proportions of patients that achieved full recovery.
Results:One hundred and thirteen patients were enrolled. Multivariate analysis showed that only initial DOSS was significantly associated with swallowing recovery (13.0% for non-oral feeding vs. 35.6 % for a modified diet).
Conclusion:Initial swallowing status (as determined by VFSS findings) is strongly associated with swallowing recovery in post-ischemic stroke patients. Assessments of dysphagia are important for predicting dysphagia recovery and planning management strategies.
