Abstract

Background: Dysphagia after acute ischemic stroke is frequent and increases the risk of pneumonia, insertion of feeding tube, hospital length-of-stay and rates of discharge to institutional care. However, the financial impact of dysphagia after acute ischemic stroke is not well understood.

Methods: Estimates were derived from published medical and economic literature to provide a range of estimates for the annual direct hospital cost of dysphagia associated with acute ischemic stroke in the United States. We also estimated the cost savings associated with a hypothetical new therapeutic intervention under a variety of assumptions.

Results: The 1-year costs per patient of acute hospital and post hospitalization care were $67,100 to $112,400 in acute ischemic stroke patient with dysphagia and $54,0310 to $51,979.8 in acute ischemic stroke patient without dysphagia in the two models. The estimated incremental cost in United States for ischemic stroke patients with dysphagia was $ 4,610,038,961.13 (95% confidence interval [CI] $3,796,502,674-$5,423,575,248) according to assumptions of Model 1. The estimated incremental cost in United States for ischemic stroke patients with dysphagia was $ 20,114,218,586.23 (95% CI $16564650600.42-$23663786572.04) according to assumptions of Model 2. The cost savings per year with a new therapeutic intervention ranged from $509,444,886.6 to $3,601,651,036 depending upon the magnitude of benefit.

Conclusion: Our analysis provides additional justification using financial basis for a much larger investment in research and development for treatment of dysphagia associated with ischemic stroke.
