Collaboration between geriatricians and surgeons in the perioperative treatment of older patients has been associated with improved outcomes in several nononcologic specialties. Similar associations may be possible among older patients with cancer.

We investigated the associations of geriatric comanagement of care for older patients undergoing cancer-related surgical treatment with 90-day postoperative mortality, rate of adverse surgical events, and postoperative use of inpatient supportive care services.

This retrospective cohort study assessed outcomes of

patients who received geriatric comanaged care vs those who did not using multivariable logisticregression analysis, with 90-day mortality as the outcome and geriatric comanagement of care as the main variable, with adjustment for age, sex, American Society of Anesthesiology score, Memorial Sloan ettering Frailty Index score, preoperative albumin level, operative time, and estimated blood loss.

A similar model was used to assess the association of geriatric omanagement with adverse surgical events, defined as any major complication, readmission, or emergency department visit within 30 days.

Patients aged 75 years and older who underwent an elective surgical procedure with a hospital stay of at least 1 day at a single tertiary-care cancer center between February 2015 and February 2018 were included. Data were analyzed from January to July 2019.
