Summary

This study tests a special pain management program called a Transitional Pain Service for adults having planned surgery who are at higher risk for long-lasting pain. About 126 participants will either get usual care or extra support before and after surgery to improve pain control and reduce opioid use. Researchers will also see if a computer tool can better identify which patients need this extra help.
