Risk factors for postoperative delirium in patients undergoing lower extremity joint arthroplasty

This large national cohort “identified various modifiable risk factors (including anesthesia type and pharmaceutical agents) for postoperative delirium, demonstrating possible prevention pathways.”

Benzodiazepines and gabapentinoids were associated with higher odds of delirium, whereas lower risk of delirium was associated with neuraxial vs. general anesthesia, use of NSAIDs and COX2 Inhibitors, and high vs low opioid use specifically in the over 65 year olds.
