BackgroundOropharyngeal dysphagia (OD) is a prevalent poststroke condition with severe complications and increased mortality. Poststroke OD prevalence varies among studies and there is little evidence of its related risk factors and associated complications. Objective: to evaluate the prevalence of OD after stroke and the risk factors and associated complications. MethodsWe performed a prospective longitudinal study of stroke patients consecutively admitted to a general hospital. OD was diagnosed with the volume-viscosity swallow test (V-VST). Demographic, functional status and topographical and clinical variables of stroke were collected to assess risk factors for OD. We evaluated functional status, mortality, respiratory infections, and readmissions 3 and 12months after stroke. A multivariate regression analysis determined associated risk factors for OD and for each outcome variable. Key ResultsWe included 395 stroke patients with a 45.06% prevalence of OD on admission. OD was independently associated with age (OR=1.05; CI=1.02-1.08), previous stroke (OR=2.40; CI=1.00-5.79), severity using the National Institute of Health Stroke Scale (OR=3.52; CI=1.57-7.87) and volume of the lesion (OR=1.02; CI=1.01-1.03). OD after stroke was an independent risk factor for prolonged hospital stay (P=.049; =0.938) and institutionalization after discharge (OR=0.47; CI=0.24-0.92); OD was an independent risk factor for poorer functional capacity (OR=3.00; CI=1.58-5.68) and increased mortality (HR=6.90; CI=1.57-30.34) 3months after stroke. Conclusions & InferencesPoststroke OD is prevalent and associated with poor short and long term prognosis. Stroke severity and patient status before stroke were more relevant to OD than lesion location. Systematic screening programs and early OD management could significantly improve poststroke patient outcome.
