Objective The research aimed to delineate the predictive factors of post-stroke dysphagia.

Background Dysphagia has been associated with an increased risk of stroke mortality due to the associated risk of bronchoaspiration. Early detection of dysphagia in patients with acute stroke reduces length of hospital stay and overall health care costs.

Design/Methods 414 patients diagnosed with ischemic or hemorrhagic stroke, with a speech therapist evaluation, Oxfordshire Community Stroke Project (OCSP) classification, admission National Institute of Health Stroke Scale (NIHSS) score, evaluated by the "Line of stroke care” of a stroke reference center from January to December 2017 were admitted to this retrospective observational study. The OCSP classification was used to determine stroke location. The severity scale of stroke used was NIHSS. The Dysphagia Outcome and Severity Scale (DOSS) was used for dysphagia analysis. The qualitative variables studied were: gender, stroke type, presence of dysphagia, dysphagia severity, NIHSS divided by groups < 8 and ≥ 8 and stroke location. The quantitative variables analyzed were age and NIHSS scalar score at admission performed by neurologists.

Results Gender (p = 0.801), stroke type (p = 0.884), and age (p = 0.819) were not shown to be statistically significant predictors of dysphagia. An association was found between progression of the value of NIHSS and dysphagia (p < 0.001), and to improve the analysis this score was stratified in two groups with NIHSS ≥ 8 and < 8, and were compared to the presence of dysphagia (OR = 1.947; p < 0.001), presenting sensibility (66.1%) and specificity (56.6%). Anterior stroke location in ischemic stroke (OR = 1.634; p = 0.019), also presented a significant association with a sensibility (67.23%) and specificity (44.34%).

Conclusions

NIHSS ≥ 8 and anterior circulation on the OCSP scale can be used as clinical screening tests at admission to predict dysphagia in patients with acute stroke.
