About

This randomized controlled trial evaluates whether a standardized preoperative pain education session delivered by a nurse reduces postoperative pain intensity and surgical anxiety among adult elective orthopedic surgery patients compared with usual care.

Primary outcome is postoperative pain at 24 hours. Secondary outcomes include anxiety, analgesic consumption, patient satisfaction, and length of stay

Full description

Adult patients scheduled for elective orthopedic surgery will be randomized (1:1) to receive either (a) a structured 20-30-minute preoperative pain education session plus booklet and video, or (b) usual care alone. Pain intensity measured with NRS at 1, 6,12, 24, 48h postop; analgesics recorded Day 0, 1, 2; preop anxiety measured with Surgical Anxiety Scale in both groups. Intention-to-treat analysis.
