Oropharyngeal Dysphagia (OD) increases the risk of hospitalization and the use of health services; however, it is often detected and studied in institutionalized patients with limited attention given to the community. The aim of this study was to determine the prevalence of OD and its associated factors after conducting a program consisting of a systematic assessment of OD for in patients living independently in their dwellings and requiring home-based care. We conducted a cross-sectional study involving a systematic assessment of disabled and elderly patients enrolled in a home-based primary care program at three urban centers (Barcelona, Spain). OD was assessed using the Volume-Viscosity Swallow Test. Data on morbidity, incontinence, functional independence, pressure sore risk, brain deficit, social risk, nutritional status, and healthcare utilization were collected. Prevalence was determined, and differences between OD and non-OD patients were analysed using independent tests. Associations between OD and hospital admissions, emergency department visits, emergency home ambulance use, and consultations with family physicians or primary care nurses were examined using logistic regression models adjusted for covariates. We included 1,002 patients with a mean age of 88.75 years old (SD = 8.19), 73.05% of whom were female. The prevalence of OD was 25.95% (95% CI 23.26%-28.78%). OD was associated with past pneumonia episodes (adjusted OR: 5.09, 95% CI: 2.2-11.79), increased frequency of cough and common cold (adjusted OR: 1.11, 95% CI: 1.05-1.18), and more family physician consultations (adjusted OR: 1.07, 95% CI: 1.03-1.10). These findings highlight that OD remains an underdiagnosed geriatric syndrome in the community setting. Implementing systematic OD diagnoses assessments, especially among home care-based patients could reduce the incidence of secondary pneumonia, decrease cough episodes, and lower the frequency of clinician consultations.
