Factors and Outcomes Associated With Dysphagia in Hospitalized Persons With Dementia.

Dysphagia is prevalent in older adults with dementia, particularly in the acute care setting. The objective of this study was to use an innovative approach to extract a more representative sample of patients with dysphagia from the electronic health record (EHR) to determine patient characteristics, hospital practices, and outcomes associated with dysphagia in hospitalized persons with dementia. A retrospective study of hospitalized adults (aged ≥65 years) with dementia was conducted in 7 hospitals across the greater New York metropolitan area. Data were obtained from the inpatient EHR with the following inclusion criteria: age ≥65 years; admitted to one of 7 health system hospitals between January 1, 2019, and December 31, 2019; and documented past medical diagnosis of dementia (based on International Classification of Diseases, Ninth Revision). A diagnosis of dysphagia was defined as nurse documentation of a positive bedside swallow screening, nurse documentation of "difficulty swallowing" as reason for not performing bedside swallow screening, and physician documentation of a dysphagia diagnosis. Of adults with dementia (N = 8637), the average age was 84.5 years, 61.6% were female, and 18.1% were Black and 9.3% Hispanic. Dysphagia was identified in 41.8% (n = 3610). In multivariable models, dysphagia was associated with invasive mechanical ventilation [odds ratio (OR) 4.53, 95% CI 3.55-5.78], delirium (OR 1.53, 95% CI 1.40-1.68), increased length of stay (B = 3.29, 95% CI 2.98-3.60), and mortality (OR 4.44, 95% CI 3.54-5.55). Given its high prevalence, underrecognition, and associated poor outcomes, improving large-scale dysphagia identification can impact clinical care and advance research in hospitalized persons with dementia.
