Blood marker may reveal which over-80s can survive ICU without losing independence
NCT ID NCT05233267
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study investigates whether a blood marker called neopterin can predict which patients aged 80 and older will survive an intensive care unit (ICU) stay without losing their ability to perform daily activities. Researchers will measure neopterin levels in blood samples taken within 24 hours of ICU admission and then check patients' independence three months later. The goal is to find a reliable tool to help doctors make difficult decisions about ICU admission for very elderly 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 neopterin proves reliable, it could help doctors decide which elderly patients are most likely to benefit from intensive care, avoiding unnecessary suffering and saving resources.
- What could go wrong
- This is an observational study, not a treatment trial. Neopterin may not be accurate enough to guide real-world decisions, and results may not apply to all elderly ICU patients.
