Abstract

Objectives: To study the applicability of National Institutes of Health Stroke Scale (NIHSS) in early predicting the prognosis of poststroke dysphagia in an acute ward.

Methods: This is an observational retrospective cohort study including adult patients with ischemic stroke. Patients with various factors affecting swallowing were excluded to obtain a representative sample of 165 patients. The main outcome measure was the improvements of oral intake function.

Results: The scores of facial palsy (NIHSS item 4) (odds ratio [OR]: 0.484, 95% confidence interval [CI]: 0.279-0.838, P = .0096] and language/aphasia (NIHSS item 9) (OR: 0.562, 95% CI: 0.321-0.982, P = .0430) demonstrated significantly negative effects on the early improvement of dysphagia. Moreover, the improved patients had a 4.14-fold (95% CI: 2.53-11.23, P = .005) increased odds of returning home compared with nonimproved patients.

Conclusions: Our findings provide evidence that early improvement of poststroke dysphagia was significantly associated with a favorable discharge destination and NIHSS items of facial palsy and language/aphasia can be used at the onset of stroke to identify dysphagic patients at risk of achieving limited improvement. These findings provide valuable prognostic indicators for clinicians to make a precise outcome prediction at very early stage.
