Background Femoral hernias are associated with significant morbidity and mortality due to risk of strangulation. Frailty has shown to be strongly associated with adverse outcomes. A modified five-factor frailty index (mFI-5) is a simple validated predictor of postoperative complications and mortality within the ACS-NSQIP® database. This study aims to evaluate the impact of frailty and age on 30-day outcomes after femoral hernia repair. Methods Patients who underwent femoral hernia repair were queried using the ACS-NSQIP database (2017) and divided into two groups based on frailty score (FS): Frail (FS = 1-5) and Non-frail (FS = 0). We evaluated the association between postoperative outcomes and frailty, age, sex, presentation, ASA class, timing of surgery, and surgical approaches. Univariate analysis followed by a multivariable logistic regression model was performed to evaluate postoperative morbidity. Results Of a total of 1,295 patients, 540 (42.7%) were in the Frail group. No differences in sex and race proportions were observed between groups. The Frail group had a higher rate of serious morbidity (4.4% vs 1.9%, P < .001), overall morbidity (7.8% vs 3.4%, P < .010), readmission rate (5.4% vs 2.3%, P = .003), and median (IQR) hospital length of stay (1 [0, 4] vs 0 [0, 1] days, P < .001). In multivariable analysis, male sex, presentation with complication, emergency surgery, and FS were associated with increased odds of overall morbidity. All deaths were in the Frail group. Conclusion(s) Frailty, male sex, presentation with obstruction/strangulation, and emergency surgery are independent predictors of increased 30-day morbidity. Thirty-day mortality was noted in the Frail group.
