Nurse delivered endoscopy

The multicentre randomised controlled trial by Williams and colleagues (doi:10.1136/bmj.b231) compares the clinical effectiveness of doctors and nurses undertaking upper and lower gastrointestinal endoscopy.

The studies found no significant difference in clinical outcomes, although doctors seemed to be more cost effective.1 2
