Table 5. Univariate analysis of outcomes among young vs. old adults with AIS hospitalizations.
Percentage in brackets are column % indicates the direct comparison between YA vs. old patients among patients with AIS.
*Morbidity = length of stay >10 days (>90th percentile of AIS hospitalization) and discharge to non-home (transfer to short-term hospital, skilled nursing facility, intermediate care facility, or home health care).
APR-DRG: All Patients Refined Diagnosis Related Groups; SNF: skilled nursing facility; ICF: intermediate care facility; SE: standard error; AIS: acute ischemic stroke
