A quick ultrasound of the thigh may reveal frailty in older ICU patients
NCT ID NCT06523348
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
Researchers in Toulouse are testing whether a bedside ultrasound of the quadriceps muscle can diagnose frailty in adults aged 65 and older admitted to intensive care. They will compare the ultrasound measurements with the standard Clinical Frailty Scale, which relies on a clinician's judgment. The study involves 70 participants and follows them for three months to see if the ultrasound predicts outcomes. If the method works, it could offer a more objective, quick way to assess frailty in critically ill older adults.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ultrasound measurement of the quadriceps muscle thickness
- What this could lead to
- If it works, a simple bedside ultrasound could help doctors identify frail older patients in intensive care more objectively, potentially guiding better care decisions.
- What could go wrong
- This is a small, single-center diagnostic study, so results may not apply broadly. Ultrasound measurements can vary between operators, and the test may not match the clinical scale in all patients.
