To determine the impact of frailty on postoperative readmission, morbidity, and mortality among patients undergoing surgery for endometrial cancer.
Patients with endometrial cancer undergoing hysterectomy between 2010 and 2014 were identified using the Nationwide Readmissions Database. Frailty was classified using criteria outlined by the Johns Hopkins Adjusted Clinical Groups Frailty Diagnoses Indicators. Primary outcomes were divided by index surgical admission (intensive level of care, mortality, non-routine discharge), 30-days (readmission and mortality), and 90-days (readmission and mortality) after discharge. Multivariable log linear regression models were fit to analyze the effect of frailty on these outcomes, adjusting for patient, hospital, and clinical factors.
From 2010 to 2014, there were 144,809 surgical endometrial cancer cases with a 1.8% frailty rate. Frailty was associated with an increased risk of intensive level of care (aRR = 3.61, 95% CI: 2.95, 4.42), non-routine discharge (aRR = 1.59, 95% CI: 1.51, 1.68), and inpatient mortality (aRR = 2.05, 95% CI: 1.68, 2.51) during index admission. Frail patients were more likely to be readmitted within 30 days (RR 1.33, 95% CI 1.22–1.47) and 90-days (RR 1.21, 95% CI 1.12, 1.32), and were at increased risk of mortality during their 30-day readmission (aRR = 1.75, 95% CI: 1.28–2.39). Frailty was not associated with 90-day mortality. Hospitalization costs for frail patients were significantly higher than for non-frail patients during index admission and readmissions within 30 and 90 days (p < 0.05 for all).
Frailty affects postoperative outcomes in endometrial cancer patients and is associated with an increased rate of readmission and 30-day mortality among those who are readmitted. Gynecologic cancer providers should screen for frailty and consider outcomes in frail patients when counseling them for surgery.
