An international consortium/research group from Canada (Prof. Phil Woods), Denmark (drs Jesper Bak, Lene Berring and Jacob Hvidhjelm) , Norway (Dr. Roger Almvik) and UK (prof Richard Whittington) is currently working on a scoping review on the use of BVC. According to Grant and Booth (2009), Scoping reviews are "preliminary assessment of potential size and scope of available research literature. Aims to identify nature and extent of research evidence (usually including ongoing research)." Our aim is to explore the breadth or extent of the literature, map and summarize the evidence, and inform future research regarding the BVC. The litterature search is now finished and we have identified 63 publications in various settings from around the world.
