Wrong-site surgery, retained surgical items, and surgical fires: a systematic review of surgical never events.
Approach to Improving Safety
Setting of Care
This systematic review examined surgical never events following the implementation of the Universal Protocol in 2004. Incidence estimates for retained surgical items and wrong-site surgery varied across studies, with median event rates approximately 1 per 10,000 and 1 per 100,000 procedures, respectively. There were many causes and contributing factors to these errors, but root cause analyses commonly called for better communication.
