Preoperative frailty is a risk factor for non-home discharge in patients undergoing surgery for endometrial cancer

Our objective was to examine the association of the modified frailty index (mFI) and non-home discharge in patients undergoing surgery for endometrial cancer (EMCA).

Patients who underwent surgery for EMCA from 2011 to 2012 were identified from the American College of Surgeons - Nastional Surigical Quality Improvement Project (ACS-NSQIP) database. Current Procedural Terminology (CPT) codes were used to identify surgical characteristics. We excluded patients who were already living in a non-home facility. To determine frailty, we used the NSQIP frailty index. For analysis purposes, patients with an mFI score ≥0.18 were defined as frail. Patients were divided into groups based on discharge destination. Logistic regression were used to identify predictors of post-operative non-home discharge.

1216 patients were identified. 26 (2.1%) were discharged to a non-home facility. On multivariate analysis, patients who were discharged to a non-home facility were older (OR 1.09, 95% CI 1.04-1.14, p < 0.001), had a higher Body Mass Index (BMI) (OR 1.08, 95% CI 1.04-1.12, p < 0.001), were more likely to have disseminated cancer (OR 10.02, 95% CI 2.28-44.1, p = 0.002), and were frail (OR 1.95, 95% CI 1.91-5.01, p = 0.008). Undergoing minimally-invasive surgery was independently associated with discharge to home (OR 0.165, 95% CI 0.059-0.458, p = 0.001).

Frailty is associated with increased risk of non-home discharge in patients undergoing surgery for EMCA. The mFI can be easily calculated using patient characteristics that are readily available pre-operatively. This information can be used for pre-op counseling and to facilitate appropriate and timely discharge planning.
