Learning from patient safety incidents: The Green Cross method.

A diverse array of methods exists to report and learn from patient safety incidents. This study describes post-anesthesia care unit (PACU) nurses' experience with the Green Cross method, a proactive method to report and learn from patient safety incidents occurring in the prior 24 hours. Nurses reported more openness and transparency after implementation of the Green Cross method; however, they also reported that subsequent improvements were insufficient.
