The guideline aims to give directions towards an evidence based use of clinical history and laboratory assessment to determine the bleeding risk associated with planned surgical or other procedures. This was published in 2008 which antedates much of the work on bleeding assessment tools now used for von Willebrand disease but in any event the two problems may not be entirely the same. As a result the major part of the guideline considers the available tests for assessment of haemostatic function, their principles, sensitivity and specificity. Overall the guidelines argue against indiscriminate coagulation testing prior to surgery. Note that there are also NICE guidelines on this topic.
