Despite advances in perioperative care, short-term and long-term postoperative complications are still experienced by many patients, which is of special relevance to the older adult population, considered to be high-risk surgical candidates because of less functional reserve and comorbidity burden. Through the implementation of prehabilitation programs, patients can be optimized to handle the physical and mental stress of surgery. Benefits have been described in a variety of surgical populations, but more studies targeting older surgical patients are needed. These studies should include standardized prehabilitation protocols and large sample sizes to avoid the limitations of the existing prehabilitation literature.
