The Geriatric Patient: Frailty, Prehabilitation, and Postoperative Delirium

Area of Science:

• Geriatric Medicine
• Surgical Outcomes Research
• Perioperative Care

Background:

• Chronologic age (≥65 years) is a traditional but limited definition for geriatric patients.
• Chronologic age is an independent risk factor for postoperative complications and adverse surgical outcomes.
• Frailty, reflecting biological age, is a more accurate measure of patient vulnerability to surgical stress.

Purpose of the Study:

• To highlight the limitations of chronologic age in assessing surgical risk in the elderly.
• To introduce frailty as a superior biomarker for surgical vulnerability.
• To emphasize the role of prehabilitation in optimizing patients for surgery.

Main Methods:

• Review of existing literature on geriatric definitions, surgical risk, frailty, and prehabilitation.
• Analysis of the relationship between chronologic age, frailty, and surgical outcomes.
• Exploration of prehabilitation's impact on functional, cognitive, nutritional, and emotional status.

Main Results:

• Chronologic age alone is insufficient for predicting surgical outcomes.
• Frailty is a more reliable indicator of patient resilience or vulnerability to surgical stress.
• Prehabilitation demonstrates potential in enhancing patient preparedness for surgery.

Conclusions:

• Frailty assessment should be prioritized over chronologic age in geriatric surgical patients.
• Prehabilitation is a promising strategy to mitigate surgical risks and improve outcomes.
• Addressing frailty and implementing prehabilitation can reduce postoperative complications, including delirium.
