Core Tip
Core Tip: Aging is associated with frailty, increased comorbidities, and worse postoperative outcomes. Some studies on prehabilitation showed its potential in improving postoperative outcomes for elective colorectal surgery, but selection criteria and prehabilitation protocols are heterogeneous. Through propensity score matching, this study showed that prehabilitation in non-frail older patients (≥ 65 years) did not improve short-term outcomes and 1-year mortality. Open surgery was an independent predictor of 1-year mortality. Consideration should be made to modify and stratify the selection criteria for prehabilitation based on frailty scores and comorbidity burden to identify the group of patients who will best benefit given finite resources.
