Abstract
Purpose: Poststroke dysphagia and poststroke depression (PSD) can have devastating effects on stroke survivors, including increased burden of care, higher health care costs, poor quality of life, and greater mortality; however, there is a dearth of research examining depression in patients diagnosed with dysphagia after stroke. Thus, we aimed to study the incidence of PSD in patients with poststroke dysphagia to provide foundational knowledge about this patient population. Method: We conducted a retrospective, cross-sectional study of individuals with a primary diagnosis of acute ischemic stroke (AIS) and secondary diagnoses of dysphagia and/or depression using administrative claims data from the 2017 Medicare 5% Limited Data Set. Results: The proportion of depression diagnosis in patients with poststroke dysphagia was significantly higher than the proportion of depression diagnosis in those without poststroke dysphagia during acute hospitalization: 12.01% versus 9.52%, respectively ( p = .003). Conclusions: Our results demonstrated that persons with poststroke dysphagia were as, or slightly more, likely to have PSD compared to the general stroke population, and to our knowledge, they establish the first reported incidence of PSD in Medicare patients with dysphagia after AIS. Future research is warranted to further explore the effects of PSD on poststroke dysphagia.
