Can a simple frailty test predict who will have complications after surgery?
NCT ID NCT06889545
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
This study compares five different frailty assessment tools to see which one best predicts complications after surgery in people aged 70 and older. Researchers will evaluate each tool's ability to identify those at higher risk for problems like infections or longer hospital stays. The goal is to find a practical test that can be used during routine pre-surgery visits to improve care for older patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could identify a simple, reliable way to spot older patients at higher risk before surgery, helping doctors plan safer care.
- What could go wrong
- This is an observational study, not a treatment trial. It compares existing tools but does not test a new intervention, so it may not change practice directly.
