Ultrasound-Guided Regional Anesthesia by Emergency Physicians for Hip Fractures and Delirium

Can a simple knowledge-to-practice intervention increase use of point-of-care ultrasound-guided regional anesthesia (POCUS-GRA) in the emergency department for older people with hip fractures, and does this reduce delirium?In this randomized clinical trial, a knowledge-to-practice intervention improved POCUS-GRA use, and nerve blocks were safe and quick. Despite suboptimal uptake and block effectiveness, odds of delirium were reduced in the intervention group.In this study, nerve blocks provided by emergency department physicians after a feasible training program reduced delirium.
