Emergency High-Risk Surgery Costs Older Adults a Month of Home Time

Older adults who undergo high-risk emergency abdominal surgery may spend far less time living independently at home in the year after their operation than peers who receive lower-risk procedures, according to a new study in the Journal of the American College of Surgeons (JACS).

Rather than focusing only on survival, researchers used a patient-centered metric called “healthy days at home.” This measure estimates how many days older adults remain living independently at home after surgery, explicitly excluding time spent in hospitals, rehabilitation centers, or nursing facilities.

The analysis included nearly 30,000 Medicare beneficiaries aged 66 and older. Investigators examined seven common emergency general surgery procedures and stratified them into higher- and lower-risk categories based on operative complexity and expected impact on recovery.

High-risk operations included procedures such as laparotomy, colectomy, small bowel resection, peptic ulcer repair, and lysis of adhesions. Lower-risk procedures included appendectomy and cholecystectomy. This setup allowed the team to compare long-term functional outcomes across clinically distinct emergency surgeries.

On average, patients receiving high-risk surgery spent about one month fewer at home during the following year (308 vs. 345 days) compared with those undergoing lower-risk procedures. The difference highlights a recovery burden that traditional metrics can underestimate.

Mortality was also higher after high-risk operations (18.1% vs. 5.2%), aligning functional decline with increased risk of serious complications. However, the most striking part of the findings involves who is most vulnerable to losing independence.

After statistical adjustment, older age, Black race, dementia, multiple chronic conditions, frailty, and receiving care in the Midwest or South were each associated with fewer healthy days at home. Dementia, in particular, corresponded to roughly 50 fewer days at home, and its impact was especially pronounced for patients undergoing lower-risk operations.

Frailty was strongly linked to reduced healthy days at home as well, with effects that were especially evident following high-risk procedures. The authors argue that these signals can improve shared decision-making between surgeons, patients, and families.

They also emphasize that “healthy days at home” can complement survival-focused counseling, supporting conversations about what recovery realistically looks like—especially for older adults whose primary goal may be returning to, and staying at, home.

Finally, the work underscores a broader shift toward long-term, patient-centered outcomes in emergency and geriatric surgery—suggesting that better preoperative identification of cognitive and functional risk could help target supportive interventions after emergency operations.
