Frailty: How to assess, prognostic role.

Area of Science:

• Geriatric Medicine
• Surgical Outcomes Research
• Clinical Epidemiology

Background:

• Frailty is clinically significant in surgical patients but lacks a standardized definition or measurement tool.
• Existing validated frailty measures are often too resource-intensive for routine preoperative screening.

Purpose of the Study:

• To review definitions and assessment methods for frailty, including the phenotypic and cumulative deficits models.
• To examine the association between preoperative frailty and adverse postoperative outcomes in surgical populations, particularly after cancer surgery.
• To emphasize the need for improved preoperative care and interventions to mitigate surgical risks.

Main Methods:

• Narrative review of literature on frailty definitions and assessment.
• Analysis of studies investigating frailty as a predictor of surgical outcomes (mortality, morbidity, length of stay, complications).

Main Results:

• No consensus exists on frailty definition or measurement in surgical contexts.
• Frailty is an independent risk factor for increased mortality, morbidity, and length of stay post-surgery.
• Research-focused tools exist but are not practical for widespread preoperative screening.

Conclusions:

• Standardized, resource-efficient frailty assessment is crucial for surgical patients.
• Preoperative care must prioritize patient-centered goals and explore interventions to improve postoperative outcomes.
• Further research is needed on patient-oriented functional and cognitive outcomes and frailty interventions.
