Clinical variation is evident throughout healthcare systems and services internationally. Although statistical and framework approaches are well established for determining variation, there is less clarity on how to define variation which warrants action. This review seeks to identify methods and frameworks used to determine when variation is considered unwarranted and when change is justified. It then explores the models of facilitated feedback that have been used to respond to variation and their effectiveness. Based on their findings the researchers provide a number of points for consideration when developing a framework for the NSW context.
