This study examines the patient- and hospital-level variation in time to initiation of inpatient management among patients admitted to general medical services.
Abstract Inpatient boarding (holding patients in the emergency department [ED] while awaiting an inpatient bed) is associated with increased risk of delirium, medication safety events, and hospital mortality in older adults. We investigated boarding trends across age strata to determine if older patients had elevated rates compared to younger patients. Administrative data for ED encounters resulting in admission from 3 healthcare systems (2 Midwest, 1 Northeast) from 1/1/19 to 12/31/24 were reviewed. Age was categorized by strata: < 21, 21-64, 65-74, 75-84, and ≥ 85. Based on the CMS Age Friendly Hospital Measures, the proportion of patients boarding for 3+ hours was calculated within each year and age strata. Boarding rates varied substantially by system and age group. At Systems 1 (S1) and 3 (S3), ≥ 85 patients had the highest rates (S1: 54.9%, S3: 70.9% in 2024) and, at System 2 (S2), all adult patients (21+) had similar rates (20.5-22.4% in 2024). Boarding rates increased in all systems over the study period. At S1 and S3, < 21 patients had the highest average yearly increase in boarding (S1: 7.4%, S3: 3.9%). At S2, boarding increased most in ≥ 85 (23.9%). In this multisystem evaluation, approximately one in two older adults experience ED boarding, with the oldest patients (≥ 85) facing the greatest exposure to boarding in recent years. These findings taken alongside known delays and safety risks associated with boarding and patient care complexity amongst the oldest adults may result in disproportionate harm to some of the most vulnerable patients.
Stranded in the emergency department: an analysis of boarding trends in older adults in the United States
Abstract Introduction The rapidly ageing population and multimorbidity are associated with increased emergency department (ED) visits by older adults. In the ED, older adults have higher risk of hospitalization, functional and cognitive decline, and mortality. Boarding, holding admitted patients in the ED awaiting a hospital bed, exacerbates these negative outcomes, which disproportionately affect older adults. Methods We conducted a cross-sectional analysis to investigate US boarding trends by age using clinical administrative data from 5 health systems and publicly available NHAMCS data from 2018 to 2024. Results Boarding ≥3 h in the ED has increased across diverse hospital types, with oldest adults (85+) facing the greatest risk (System 4: IRR [95% CI] = 1.18 [1.15-1.20], System 5: IRR [95% CI] = 1.20 [1.17-1.23], System 3 [Community Hospital]: IRR [95% CI] = 1.25 [1.19-1.33]). These results were recapitulated at the national level in NHAMCS (IRR [95% CI] = 1.30 [1.05-1.61]). Discussion The trend of increased boarding has serious implications for patients, caregivers, and health systems. The 2025 CMS Age-Friendly Hospital Measure offers opportunities to improve processes and procedures to mitigate the negative effects of hospital boarding on older patients. We highlight opportunities to address this challenge, including ongoing quality improvement initiatives, bed prioritization algorithms, and alternate admission pathways.
