Rising ED boarding for older adults

Emergency Department Boarding for Older Adults: The Impact of Geography, Temporal Trends, and Dementia Status
Annals of Emergency Medicine · Added 19 September 2026

US national survey analysis of 4.45 million admissions of adults aged ≥65 (2015–2022) — 85% boarded ≥2 hours in the ED, mean boarding time rose from 138 minutes in 2018 to 343 minutes in 2022 and roughly 501 minutes for patients with Alzheimer's-related dementia, with the worst growth in metropolitan areas and among those ≥75.

Study type
Cross-sectional
Design
Cross-sectional analysis of national survey data (NHAMCS 2015–2022)
Participants
4.45 million weighted hospital admissions of adults aged ≥65 with complete data
Main finding
85.2% boarded ≥2 hours; mean boarding time rose from 138 minutes in 2018 to 343 minutes in 2022, reaching 501 minutes (95% CI -20 to 1,022) with Alzheimer's disease-related dementia; each calendar year associated with 3.2% increase in 4-hour boarding and 15.3 extra minutes.
Caveat
US survey data with wide confidence intervals, especially the dementia subgroup estimate; in-hospital system issue.
Bottom line
Context only

Why it matters in Australia (Medium relevance). US access-block data we can't act on directly, but the off-stretcher delays it describes are familiar at Canberra Hospital

Learning goal

Understand how prolonged emergency department boarding affects older adults, especially those with dementia, in Australian hospitals.
