Prehabilitation for the Frailty Syndrome: Improving Outcomes for Our Most Vulnerable Patients.

Anesthetists are increasingly faced with the challenge of delivering perioperative care to frail older people. Patients with frailty undergoing surgical intervention are at a significantly increased risk of perioperative complications, mortality, and longer length of stay. Moreover, frailty is often associated with multimorbidity and a range of geriatric syndromes including functional dependency, cognitive impairment, and malnutrition which further increases risk and complexity of care. There is a growing body of evidence that prehabilitation-intervention delivered during the preoperative period to improve overall health and function-can improve postoperative outcomes for patients undergoing surgery. However, whether this vulnerable population stand to benefit from prehabilitation is less clear. We review the evidence for prehabilitation for patients with frailty including whether the risks associated with and outcomes from surgery can be modified through comprehensive geriatric assessment.
