New study aims to forecast chronic pain after surgery using patient data
NCT ID NCT04864275
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study followed 2500 adults having major surgery to see if we can predict who will develop persistent pain 3 to 6 months later. Researchers collected information on patients' history, physical and mental health, and daily experiences using smartphone surveys. The goal is to find patterns that could help identify high-risk patients before surgery.
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 lead to a tool that helps doctors predict which patients are at risk for long-term pain after surgery.
- What could go wrong
- This is an observational study, not a treatment trial. It may not produce a usable prediction tool, and results may not apply to all patients.
