Hospital readmissions after stroke in patients with and without dementia and undergone gastrostomy tube placement

Abstract

IntroductionPercutaneous endoscopic gastrostomy (PEG) in stroke patients is associated with high hospital readmission rates. The impact of dementia on hospital readmission rates in stroke patients who underwent PEG is unknown. We aimed to assess if stroke patients with dementia who undergo PEG are at risk for readmission. MethodsWe conducted a retrospective, observational study using the National Readmission Database from Healthcare Cost and Utilization Project (HCUP) from 2013 to 2014. Patients 65 years or older admitted with stroke and who had gastrostomy in the same hospital admission were included. We compared readmission rates at 30 and 60 days between patients with and without dementia and assessed the five most common readmission diagnosis. The association of dementia and hospital readmission was analyzed. ResultsOut of 492,727 patients over 65 who had stroke/PEG, 45,477 (9 %) had dementia. Patients with dementia underwent PEG placement more frequently than those without dementia (4.3% vs. 3.3%, respectively). There was no significant difference in the 30 and 60 days readmission rates between those with dementia and those without. Septicemia, aspiration pneumonitis and complications from the procedure were among top five readmission diagnosis. Dementia was not significantly associated with 30-day (odds ratio (OR) 0.99, 95% CI 0.87-1.13) or 60-day (OR 1, 95% CI 0.89-1.12) readmissions. ConclusionsRisks and benefits of gastrostomy in older adults with stroke and dementia should be honestly discussed with patients and their families since it exposes them to a higher risk of hospital readmission due to aspiration pneumonitis and complications from PEG.
