Rawlins delivered several eponymous lectures at the RCP, including the
Bradshaw Lecture in 1986. In 1994 he gave the RCP's
William Withering lecture. In it, contrary to the widely held belief that
digitalis would unlikely pass modern day licensing regulations, he said of Withering's 1785
An account of the foxglove and some of its medical uses ... "Its contents would do justice to an expert report accompanying a Product Licence application to the drug regulatory authority of any state in the European Union". The lecture called for abandoning
hierarchy of evidence at a time when Rawlins headed NICE, the UK's main independent agency whose purpose was to assess scientific evidence of medical treatments. The problem with RCTs, he stated, is that they are too generalised. He pointed out that science includes the not so exact but important "
judgement". Rawlins quoted
William Blake's observation .. "God forbid that truth should be confined to mathematical demonstration", and said in his lecture: The notion that evidence can be reliably placed in hierarchies is illusory. Decision makers need to assess and appraise all the available evidence irrespective of whether it has been derived from randomized controlled trials or observational studies; and the strengths and weaknesses of each need to be understood if reasonable and reliable conclusions are to be drawn. According to philosopher
John Worrall, if other physicians in the field of
evidence based medicine held similar views to Rawlins, his [Worrall's] own philosophical work on evidence based medicine might not be required. == Honours and awards ==
