Classifying frailty in the ventral hernia population

Frailty is increasingly recognized as a preoperative predictor of adverse outcomes following various surgical procedures. Our study aims to compare validated frailty measures in the ventral hernia population, as this is a common elective procedure with a paucity of data regarding frailty prevalence.

Patients aged 18 years or older with planned ventral hernia repairs were prospectively enrolled in our single-institution study from January 2023 through June 2023. After obtaining informed consent, patients completed the Fried Frailty Index (FFI), the FRAIL Scale, and the Strength, Assistance walking, Rising from a chair, Climbing stairs, and Falls (SARC-F) questionnaires, as well as the standard completion of the Patient-Reported Outcomes Measurement Information System (PROMIS) measures at their preoperative clinic appointment. Chart review was performed for baseline demographics and comorbidities. The Modified Frailty Index (mFI-11) and the Charleston Comorbidity Index (CCI) were calculated.

A total of 63 patients were enrolled in our study. On average, the population was 60 years old, with a BMI of 32.4 kg/m², a CCI of 3, and on 10.5 medications preoperatively. Overall, 12 patients (19%) screened positive for frailty by the mFI-11, 17 patients (27%) by the FFI, 15 patients (23.8%) by the FRAIL Scale, and 15 patients (23.8%) screened positive for sarcopenia by SARC-F. The FFI and the FRAIL Scale were strongly correlated with the other measures by Spearman's rank-order correlation (p < 0.05). On multivariate regression analysis, a longer Timed Up and Go test was associated with screening positive for frailty or sarcopenia (OR 1.896, p = 0.016).

In this study, we find that frailty is more prevalent than previously reported in the literature by any measure used. Both the FRAIL Scale and FFI strongly correlate with the other tools investigated. Surgeons should consider using these assessments preoperatively to estimate frailty and guide operative planning as well as shared decision-making.
