  • To accumulate data with a commitment to improve the range of surgical information available, which in turn helps surgeons to continually assess and raise the standard of patient care.
  • Promote research projects using the registry data through an impartial requisition queue system where all contributing members get an opportunity to publish their original research.
  • Help facilitate the entire patient care pathway process to improve outcome and practice from own data.
