Blood cell ratio may flag delirium risk in elderly surgery patients
NCT ID NCT07322744
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at whether a simple blood test measuring the ratio of two types of white blood cells (lymphocytes to monocytes) could help predict postoperative delirium—a state of confusion after surgery—in older adults. Researchers studied over 6,400 surgical patients aged 65 and older, also considering their frailty status. The goal was to see if this blood marker could better identify those at risk, potentially leading to earlier preventive measures.
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 help doctors identify older patients at higher risk of confusion after surgery, allowing for better preventive care.
What could go wrong
This is an observational study, not a treatment trial. It cannot prove cause and effect, and results may not apply to all surgical patients.
