Abstract TP157: Functional Oral Intake Scale is Associated With Poorer Outcomes Following Stroke
Background: Stroke is the leading cause of disability in adult life. Oropharyngeal dysphagia occurs in 65-90% of patients, and its identification in the acute phase of stroke can prevent complications. Objective: Verify whether Functional Oral Intake Scale (FOIS) score during stroke hospitalization is associated with functional capacity, as assessed by the modified Rankin Scale (mRs), and mortality 90 days after stroke. Methods: A prospective cohort study evaluating 201 patients hospitalized in the Stroke Unit was carried out. Dysphagia was evaluated during hospitalization using both a specific protocol to evaluate swallowing biomechanics and FOIS, in which FOIS 1-3 - tube feeding, 4-5 - oral feeding requiring food consistency changes, and 6-7 - oral feeding with no changes in food consistency. mRs≥3 90 days after discharge was considered disability. The data were adjusted for the NIHSS score, sex, age, type of stroke, and presence of thrombolysis. Significance level of 5%. Results: Of the 201 patients evaluated, 42.8% (86) who had dysphagia were older, had a higher severity of stroke, and pneumonia rate . A FOIS score of 6-7 may be a protective factor against disability (mRs≥3) (OR:0.17; CI:0.005-0.56; p=0.004), and FOIS 1-3 at hospital discharge increased the risk of mRs≥3 (OR:14.97; CI: 2.68-83.65; p=0.002) and mortality (OR:9.79; CI:2.21-43.4; p=0.003) within 90 days after stroke. Pneumonia was the leading cause of death, however dysphagia and FOIS 1-3 at discharge were associated with death from any cause. Important to highlight that the interaction of FOIS 1-3 at discharge and pneumonia further enhanced mortality chance (OR:113; CI:1.40-9.097; p=0.035). Conclusion: Dysphagia or FOIS 1-3 at discharge are markers of poor prognosis after stroke. Our data suggest the importance of early evaluation of dysphagia and closely monitoring the tube fed patients following stroke.
