RESUMEN
The challenging circumstances of the COVID-19 pandemic caused a regression in baseline health of disadvantaged populations, including individuals with frail syndrome, older age, disability, and racial-ethnic minority status. These patients often have more comorbidities and are associated with increased risk of poor postoperative complications, hospital readmissions, longer length of stay, nonhome discharges, poor patient satisfaction, and mortality. There is critical need to advance frailty assessments to improve preoperative health in older populations. Establishing a gold standard for measuring frailty will improve identification of vulnerable, older patients, and subsequently direct designs for population-specific, multimodal prehabilitation to reduce postoperative morbidity and mortality.
