Dysphagia and associated factors among patients with acute ischemic stroke in Vietnam.

Abstract

Dysphagia is considered an important issue in managing and treating acute stroke, but there are currently no studies investigating this issue, especially for patients with acute ischemic stroke in Vietnam. Thus, we conducted this study to determine the prevalence of dysphagia and associated factors of dysphagia in patients with acute ischemic stroke in Vietnam. From June 2020 to January 2022, a cross-sectional study of patients with acute ischemic stroke was conducted in a tertiary hospital in Vietnam. The dysphagia was evaluated through a bedside screening test using the Gugging Swallowing Screen (GUSS). Factors associated with dysphagia were analysed using univariate and multivariate logistic regression. The prevalence of dysphagia in patients with acute ischemic stroke was 71.6%, in which the mild, moderate and severe dysphagia accounted for 37.5%, 12.4% and 21.7%, respectively. Dysphagia significantly associated with age group 50-59 (OR=2.2, 95% CI: 1.2-4.2), age group 60-69 (OR=1.9, 95% CI: 1.04-3.4), age group >70 (OR=2.2, 95% CI: 1.2-4.2), brainstem (OR=4.0, 95% CI: 2.1-7.4), having communication disorder (OR=1.5, 95% CI: 1.1-7.4) and having facial paralysis (OR=17.9, 95% CI: 12.0-26.8). Our study showed that the prevalence of dysphagia is high among patients with acute ischemic stroke in Vietnam. Intervention solutions should focus more on patient groups of higher age group, brainstem stroke, communication disorder and facial paralysis.
