Stroke is a major etiological factor in dysphagia. The purpose of this study was to investigate the factors affecting difficulty of oral intake in patients with acute cerebrovascular disorder.
Two hundred and fourteen stroke patients with stroke-related dysphagia who entered an emergency hospital between March 2009 and March 2010 were recruited. Multivariate analyses were performed to identify variables significantly associated with the possibility of oral intake.
The mean age of the patients was 76.8 (SD 12.7) years old. A total of 158 patients suffered from ischemic stroke while 56 suffered from hemorrhagic stroke. At the point of discharge from the hospital, 107 patients (50.0%) resumed a regular diet. Logistic regression analysis identified four factors that significantly predicted the resumption of oral intake: a lesion limited to the right hemisphere; a score＞0 on the Barthel Index; normal swallowing sound in cervical auscultation; a profile score of 4 or above in the food test. The sensitivity and specificity of the type for forecasting oral intake were 89.7% and 78.5%, respectively. The probability of successful oral intake was 99.7% when all five factors were excellent values, but was 9.6% when all five factors were poor values.
These findings may be used to predict which patients with stroke-related dysphagia can remove the feeding tube and achieve oral intake before being discharged from an emergency hospital.
