Research by a group of Boston-area doctors suggests older adults are spending more time than they should in hospital emergency departments, substantially increasing their risk of immobility and delirium.
The study, which examined trends in older adults’ ED stays, was published in June in JAMA Internal Medicine, a publication of the Journal of the American Medical Association.
What the researchers found was a substantial increase in the proportion of adults with prolonged length of stay and boarding times over the past eight years.
Based on health records from more than 1,600 hospitals and 295 million adults aged 65 years or older, 20% of emergency department patient encounters had a length of stay of more than eight hours at the end of 2024, an 8-percentage-point increase from the start of 2017.
This is particularly noteworthy in light of past studies that have suggested that every hour spent amongst the beeping monitors and bright lights of the typical emergency department can increase an older adult’s risk of further problems, including delirium.
In fact, such is the level of concern over this that the Centers for Medicare & Medicaid Services now requires hospitals to attest they have procedures for containing emergency department length of stays to eight hours and boarding times to three hours for a percentage of older adults.
Despite the release of its “Age-Friendly Hospital Measure,” CMS recognizes that some emergency department stays may be prolonged as a result of the need for thorough medical evaluations.
However, boarding times, defined as the wait between the decision to admit and the actual admission to an inpatient bed, are determined by a number of hospital-level factors, including bed capacity.
Here, the researchers detected a 14-percentage-point increase in older adults’ boarding times exceeding three hours, rising to more than one in three visits, over the same study period.
And they said the trend toward longer stays appears to be coinciding with more emergency department visits for older adults.
In 2022, the number of visits for the top 10 diagnoses was about 33 million for people aged 65 years or older, compared with about 23 million in 2016, according to the U.S. Centers for Disease Control and Prevention.
Meanwhile, a recent study predicted the U.S. may reach the threshold for a full-blown hospital bed shortage by 2032, which would likely further lengthen emergency department boarding times.
The new study found a small decline in the rates of prolonged emergency department stays and boarding after the COVID-19 pandemic.
But the larger patterns, coupled with the aging U.S. population and workforce shortages, lead experts to believe that conditions will only get worse, the researchers said.
Emergency departments at academic hospitals had even greater increases in both length of stay and boarding times in the new study.
In these settings, the proportion of prolonged stays increased from 19% to 30%, while the share of prolonged boarding times rose from 31% to 45%.
One reason for this may be that academic hospitals often also have cancer centers or specialty surgical centers whose planned inpatient admissions reduce the number of available beds. In addition, these hospitals often provide more complex care than other health systems.
JAMA asked Dr. Maura Kennedy, MPH, division chief of geriatric emergency medicine at Massachusetts General Hospital, to comment on the study.
Among other things, she noted the cyclical nature of prolonged emergency department stays.
When hospital beds are occupied, patient boarding times are longer, which in turn increases the likelihood of delirium or mobility issues for older patients.
This ups the chances of prolonged inpatient stays, which then leads to more occupied beds, and so on, Kennedy said.
To break the cycle, she suggested emergency departments consider a number of options.
One was a hospital-at-home program model, through which clinicians could provide hospital-level care at a patient’s residence.
Another would be to leverage the CMS Program of All-Inclusive Care for the Elderly, also known as PACE, which has been associated with lower rates of hospitalizations and ED visits.
The initiative provides all-encompassing care for older adults, especially those struggling with frailty who would otherwise need to be in a long-term care facility or nursing home.
Although it’s typically only available to patients who are dual-eligible for Medicare and Medicaid, and most states have income and asset caps for the program, Kennedy suggested it could be expanded to enable more older adults to continue to live within their community and reduce their need for emergency care.
