Frailty is the New Age: A Retrospective Study of Modified Frailty Index for Preoperative Risk Assessment in Autologous Breast Reconstruction.

 Compared with age, mFI-5 scores were better predictors of 30-day postoperative complications following autologous breast reconstruction regardless of flap type. Additionally, higher mFI-5 scores were associated with increased odds of minor and major complications. Our findings indicate that reconstructive breast surgeons should consider using the mFI-5 in lieu of age to risk-stratify patients prior to autologous breast reconstruction surgery.
