Researchers position patient frailty as a ‘surgical vital sign’

A narrative review article published this week in ACOS General Surgery zeroes in on frailty as a surgical vital sign, with discussion of risk stratification and outcomes for these patients in general surgery.

The authors, largely from the Kansas City University of Medicine and Biosciences, note that although frailty has “emerged as a critical determinant of perioperative risk … it remains underutilized in routine surgical assessment.” They write that a growing proportion of patients undergoing general surgery present with “diminished physiologic reserve that is not adequately captured by traditional risk stratification tools.”

The researchers proceed to examine frailty “as a multidimensional construct and its role as a prognostic marker in general surgery, with the aim of synthesizing current evidence on its biological basis, evaluating commonly used frailty assessment tools, and examining its impact on postoperative outcomes, including morbidity, mortality, length of stay, and discharge disposition.”

Among their findings:

• Frailty is a “strong and independent predictor of adverse outcomes across a broad range of general surgical populations.”
• “Frail patients consistently experience longer hospital lengths of stay, increased rates of intensive care unit utilization, and a greater likelihood of discharge to skilled nursing or rehabilitation facilities rather than home.”
• “These associations persist even after adjustment for age and comorbidities, underscoring frailty as a distinct and clinically meaningful construct rather than a surrogate for existing risk factors.
• “Overall, this evidence supports the conceptualization of frailty as a ‘surgical vital sign.’”

The researchers conclude that frailty is a “clinically meaningful predictor of surgical outcomes and has been shown to provide prognostic insight beyond chronological age and traditional risk stratification tools.” They state that “routine assessment of frailty has the potential to transform perioperative care by improving risk prediction, guiding clinical decision-making, and enabling targeted patient optimization.” They add that incorporating frailty into standard pre-op evaluation frameworks “may enhance patient selection, facilitate shared decision-making, and ultimately improve postoperative outcomes. Continued efforts toward standardization, integration, and prospective validation are necessary to establish frailty as a fundamental component of modern surgical practice.”
