Factors Associated with Short Hospital Stay After Combined Middle Meningeal Artery Embolization and Surgical Evacuation for Chronic Subdural Hematoma.

Among 647 patients (mean age 72.6 years; 74.0% male), 156 (24.1%) had short-stay discharge.

Median LOS was 8 days (IQR 5-15).

The 90-day composite event rate was 17.1% in short-stay versus 23.7% in long-stay patients.

Short-stay discharge was not significantly associated with the composite outcome on adjusted analysis (aOR 0.56; 95% CI 0.30-1.07; P = 0.08), generalized estimating equations (aOR 0.61; 95% CI 0.33-1.12; P = 0.11), or MICE (aOR 0.74; 95% CI 0.44-1.25; P = 0.26).
