@Tim‘s correct, but our SIGN guidelines are just guidelines and not mandatory like NICE Technology Appraisals are in England. They are much harder to meet, and although they were updated last year they are more along the lines of NICE pump guidelines of 2003! You have to be blue lighted to the hospital to meet them.
These are the (evidence based) guidelines that our Health Board are now saying they are not convinced by the evidence for adults!!! Even though several doctors in our area were involved, and no doubt paid very well, to compile and write! I can feel an FOI coming on!
