First seen Jan 12, 2026 · Last updated Jun 20, 2026 · Updated 20 times
Summary
This study looks at whether a blood marker called phosphatidylethanol (PEth), which reflects alcohol use over the past few weeks, can predict complications after surgery. Researchers will test PEth levels in 170 adults having elective surgery at University Hospitals Cleveland Medical Center who are expected to stay in the hospital for at least three days. The goal is to see if higher PEth levels are linked to problems like confusion, lung or heart issues, infections, or longer hospital stays.

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 patients at higher risk for post-surgery problems based on their alcohol use, leading to better care.
What could go wrong
This is an observational study, not a treatment trial. It may find no clear link between PEth levels and outcomes, or the results may not apply to all surgery patients.
