Our Reviewing Policy
All of our procedures are reviewed by their authors or editors at regular intervals. We send out the procedures to authors and editors at least once a year and we are in touch with our authors in between times to check whether any updating is required. As soon as we are aware of a change in policy or guidance that will affect a procedure, we initiate a review of that procedure by the author or editor; some procedures have been updated twice a year to incorporate such changes. All new procedures are subjected to double-blind peer review; existing procedures that undergo major changes also undergo further double-blind peer review.
