Atrial fibrillation (OR 1.34), heart failure (OR 1.59), diabetes (OR 1.29), and prior stroke (OR 1.50) were associated with increased likelihood of 30-day readmission. Longer hospital stay (OR 1.03 per unit increase) and greater stroke severity (NIHSS OR 1.13) were also associated with higher readmission risk.
