UrduWhile the research was not able to determine the exact reasons for this shift, the results indicate that improvements in medical treatments and cancer screening for older adults may be reducing the need for invasive surgeries, which can have negative impacts on patient’s long-term quality of life.
“There was a really stark decrease in the number of surgeries among older adults over the age of 65 throughout the study period,” said first author Daniel Rubin, MD, Associate Professor of Anesthesia and Critical Care at UChicago Medicine. “This suggests we’re getting better at determining who would benefit most from a surgery, and also possibly that we’ve developed better and less invasive alternative treatments.”
Rubin was inspired to investigate this question after reading a 2019 New York Times article discussing “routine” surgeries in adults over 85.
“This is a very personal topic for me because I was very close to my grandparents, and I saw their experiences with geriatric surgeries,” said Rubin. “My grandmother had an emergency hysterectomy at 92. Despite a stay in the intensive care unit and delirium she was able to go home and live independently afterward. My 89-year-old grandfather, on the other hand, declined a Whipple procedure for treating pancreatic cancer. So I could see early on how these big surgical interventions can really affect older adults.”
While the researchers found the overall frequency of surgery in older adults is decreasing, they did note some exceptions.
“The biggest surprise was that we saw a redistribution of surgical procedures to certain types of hospitals,” Rubin said. “There was a large shift away from rural and non-teaching urban hospitals to major academic medical centers; these were the only hospitals that saw an increase in the frequency of procedures performed on older adults. We think this may be due to increased specialization and that some procedures that may not be available at a smaller or rural institution are more likely to be offered at a larger, academic hospital.”
Another trend that was less surprising was the increase in certain procedures, such as the Whipple procedure for treating pancreatic cancer. “With pancreatic cancer, there aren’t really many less-invasive options available, and outcomes are generally good even for older adults,” Rubin said. “We perform Whipple procedures on 85- or 90-year-old adults here at UChicago Medicine simply because it is usually the most effective option.”
The researchers say these results are important because older adults often struggle to recover after major surgeries. The study found that over half of adults over 85 will require at least some transitional, post-acute medical care after a surgical procedure.
“Older adults really want to get back to their normal life after an operation,” said Rubin. “But recovery can be difficult, and the rates at which older adults require post-acute care — such as time in a rehabilitation facility or long-term care — is high. These results can help inform the decisions made by patients and providers on whether or not a surgery is the right choice for them.”
Understanding how trends in surgical procedures change over time can help illuminate which options are the most likely to lead to optimal outcomes — and determine which patients will most benefit from specific interventions.
“We’re very good at understanding overall mortality for certain procedures, but not as good at identifying which individual patients will have poor outcomes,” said Rubin. “It’s important for patients and their families to understand that these surgeries can lead to a challenging recovery trajectory for older adults, even if the surgery goes well. My hope is that this research, and other studies like it, will help us better understand how to help older adults prepare for major surgeries, and help us identify which individual patients will benefit the most from surgical intervention.”
The study, “U.S. Trends in elective and emergent major abdominal surgical procedures from 2002-2014 in older adults,” was supported by the National Institute on Aging (K23AG049106) and the National Heart, Blood and Lung Institute (R01HL126892).

Peden of the University of Southern California and the University of Pennsylvania.

About the University of Chicago Medicine & Biological Sciences
The University of Chicago Medicine, with a history dating back to 1927, is one of the nation’s leading academic health systems. It unites the missions of the University of Chicago Medical Center, Pritzker School of Medicine and the Biological Sciences Division. Twelve Nobel Prize winners in physiology or medicine have been affiliated with the University of Chicago Medicine. Its main Hyde Park campus is home to the Center for Care and Discovery, Bernard Mitchell Hospital, Comer Children’s Hospital and the Duchossois Center for Advanced Medicine. It also has ambulatory facilities in Orland Park, South Loop and River East as well as affiliations and partnerships that create a regional network of care. UChicago Medicine offers a full range of specialty-care services for adults and children through more than 40 institutes and centers including an NCI-designated Comprehensive Cancer Center. Together with Harvey-based Ingalls Memorial, UChicago Medicine has 1,296 licensed beds, nearly 1,300 attending physicians, over 2,800 nurses and about 970 residents and fellows.
