6 Review of the guidance
Because of the substantial uncertainties in many of the assumptions used for this guidance, the Committee has recommended continuous review of data relevant to the model. The Institute will consider this guidance for review in November 2008 or earlier if new relevant evidence becomes available. This may include data on:
the availability of appropriately validated decontamination methods for routine use in the NHS
the epidemiology of CJD, including data on prevalence of vCJD infectivity in the UK population
cases of transmission of CJD via surgery
the availability and performance of single-use instruments for high-risk procedures.
