Prediction of Oral Intake at Discharge with Early Assessment of Swallowing Function within 24 h after Admission: A Retrospective Cohort Study.

Dysphagia is one of the most common symptoms of stroke and can lead to other complications such as pneumonia, dehydration, and malnutrition. This retrospective cohort study evaluated the predictive value of a comprehensive swallowing assessment tool, the Mann Assessment of Swallowing Ability (MASA), in the acute phase of stroke for oral intake status at discharge. Among 1,133 consecutive patients with acute stroke, 512 patients whose swallowing function was assessed using the MASA within 24 h of admission were included. Data including demographic information, stroke severity, MASA, Oral Health Assessment Tool, body mass index, and serum albumin level were collected. Predictive factors for oral intake were analyzed using a multiple logistic regression model, and the receiver operating characteristic (ROC) curve analysis was used to determine the cutoff values of the MASA score for determining oral intake at discharge. Oral intake at discharge was established in 69.1% of the cohort (354/512). The multiple logistic regression analysis identified a higher MASA score, younger age, and higher serum albumin level as significant predictors of oral intake at discharge. The cutoff value of the MASA score for oral intake was 136.5 points, with an area under the ROC curve of 0.87. These findings suggest that the MASA is a valid tool for predicting oral intake in patients with dysphagia during the acute phase of stroke.
