What this trial studies

This study aims to collect data on pain levels, psychosocial outcomes, and opioid usage in patients undergoing elective orthopedic surgery at Duke Health. Participants will report their pain and functionality through their smartphones, allowing researchers to analyze patterns and predict which patients may be at risk for chronic opioid use. The study focuses on understanding the relationship between surgical outcomes and opioid consumption to improve post-operative care.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-90 who are scheduled for elective orthopedic surgery and have access to a smartphone.

Not a fit: Patients who cannot provide consent, do not read English, or fall outside the age range of 18-90 will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at risk for chronic opioid use, leading to better pain management strategies and reduced reliance on opioids.

How similar studies have performed: Other studies have shown success in using patient-reported outcomes to manage pain and opioid use, indicating that this approach is promising.
