AbstractFrailty is increasingly prevalent in the aging neurosurgical population and is an important component of perioperative risk stratification and optimization to reduce complications. Frailty is measured using the phenotypic or deficit accumulation models, with simplified tools most commonly used in studies of neurosurgical patients. There are a limited number of frailty measurement tools that have been validated for individuals with neurological disease, and those that exist are mainly focused on spine pathology. Increasing frailty consistently predicts worse outcomes for patients across a range of neurosurgical procedures, including early complications, disability, non-home discharge, and mortality. Evidence for interventions to improve outcomes for frail neurosurgical patients is limited, and the role of bundled care pathways, prehabilitation, and multidisciplinary involvement requires further investigation. Surgery itself may be an intervention to improve frailty in selected patients, and future research should focus on identifying effective interventions to improve both short-term complications and long-term outcomes.Copyright © 2024 Wolters Kluwer Health, Inc.
