Q: Question: Does opioid use after fracture surgery correlate with pain intensity and satisfaction with pain relief?
Answer: After operative fracture treatment, patients who take more opioids report greater pain intensity and less satisfaction with pain relief. Greater self-efficacy was the best determinant of satisfaction with pain relief. Evidence-based interventions to increase self-efficacy merit additional study for the management of postoperative pain during recovery from a fracture.
A:
yes
