When hospital length of stay begins to rise, attention often turns immediately to the emergency department. The ED is the front door, the pressure is visible, and its leaders are often the first to raise concerns about boarding, admission delays, and patients leaving without being seen.

Yet length-of-stay unplanned increases frequently begin farther downstream. Patients may have completed the clinical portion of their stay but remain in beds while teams coordinate post-acute placement, transportation, prior authorization, durable medical equipment, medication needs, or family arrangements. Across a hospital, those delays accumulate into blocked med-surg beds, delayed ICU step-downs, longer ED waits, and avoidable inpatient days.

Hospitals’ capacity margin is already narrowing. For example, a 2025 JAMA Network Open study found that average U.S. hospital occupancy reached 75.3% in 2024, compared with 63.9% before the pandemic. If staffed-bed supply and hospitalization rates remain unchanged, adult hospital occupancy could reach 85% as early as 2032.

Three signals can help leaders determine whether a throughput problem is rooted in discharge: a persistent gap between actual and geometric length of stay, a pattern of discharges drifting later into the day, and declining responsiveness across the post-acute network. Together, these signals show where time is being lost after treatment is complete.

Start with the gap that earns executive attention The most useful place to begin is the difference between actual length of stay and geometric length of stay , or GLOS. Geometric length of stay reflects the expected stay associated with a patient’s diagnosis-related group and provides an evidence-based reference point for how long similar patients typically require inpatient care.
