Summary

This large study tested whether a conversation guide and decision support tools, used by healthcare providers, could help patients choose non-drug pain relief methods after surgery. Over 81,000 adults participated. The goal was to see if this approach improves pain, physical function, and anxiety while reducing opioid use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Conversation Guide + Clinical Support (behavioral intervention)
What this could lead to
If successful, this approach could help hospitals reduce reliance on opioids for post-surgical pain and improve patient recovery through personalized, non-drug pain management strategies.
What could go wrong
This is a completed trial, but the intervention is behavioral and its effectiveness may vary across different hospitals and patient populations. It does not test a new drug or cure.
