This study aims to explore the effects of ED stay duration on inpatient medical utilization and mortality risk. Methods This study analyzed data from 42,139 patients at a central Taiwan medical center, using generalized estimating equations (GEE) to evaluate hospital stay duration and costs. Logistic regression assessed mortality risks after hospitalization. Results GEE analysis showed longer ED stays led to increased hospital stays: patients with 24–48 h in the ED had an additional 2.27 days (P
