Researchers examined patients undergoing surgery at a tertiary care academic medical center. They collected data as a part of large prospective institutional research registries from March 1, 2010, through April 30, 2016.
The study shows the most commonly used opioids were:

• Illicit drug use
• Higher pain severity
• Depression
• Higher Fibromyalgia Survey scores
• Lower life satisfaction
• More medical comorbidities
