Test to assess for frailty as a component of the preoperative assessment?

• A. Grip strength
• B. Gait speed
• C. Mini-mental status exam
• D. BMI alone

Answer: (B)

Frailty reflects diminished physiologic reserve across multiple body systems, and in the preoperative setting we want a quick, objective way to gauge it. Gait speed does exactly that: by measuring how fast a patient walks over a short distance (usually 4 meters), you get a single, integrative indicator of physical function, strength, balance, and endurance. Slower gait speed consistently predicts higher risk of postoperative complications, longer hospital stays, and greater likelihood of discharge to a facility, making it a practical and powerful preop screen for frailty. Grip strength is also related to frailty, but it requires a dynamometer and is less convenient to deploy in a busy clinic. The Mini-Mental Status Exam assesses cognitive status rather than frailty as a whole. BMI alone doesn’t capture the multidimensional nature of frailty and can be misleading about a patient’s true physiologic reserve. So using gait speed provides the most useful, efficient signal of frailty in the preoperative assessment.
