When inpatients live in the ED for hours or days, ED nurses end up running a unit inside a unit.

Boarding happens after the decision to admit has been made but there's no inpatient bed. The patient stays in the emergency department, sometimes for hours, sometimes for days. Meanwhile ED nurses are caring for new arrivals and admitted patients who need inpatient-level care, often in hallway beds.

This isn't an ED problem the ED can solve alone. A federal report from the Agency for Healthcare Research and Quality found that boarding's causes originate at the hospital or health-system level and need solutions beyond the walls of the ED. It linked boarding to excess in-hospital mortality, more medical errors and costly delays, and said it negatively affects staff (AHRQ, AHRQ Report Identifies Strategies To Reduce Emergency Department Boarding, March 2025, ahrq.gov/news/newsletters/e-newsletter/951.html). Accreditors are paying attention too. The Joint Commission's 2026 hospital National Performance Goals require hospitals to measure and set goals for mitigating and managing boarding of patients who come through the ED (Joint Commission, National Performance Goals Effective January 2026, NPG.01.03.01 EP 2, digitalassets.jointcommission.org/api/public/content/9ca8005).
