I would be interested in people's thoughts on the IACFS/ME Primer http://iacfsme.org/Home/Primer/tabid/509/Default.aspx vs International Consensus Primer http://www.hetalternatief.org/ICC primer 2012.pdf . I'm particularly interested in terms of using them on a large scale e.g. for sending to all the GPs in a country* - which would you think is better and why? I think both have a lot going for them. The IACFS/ME website says: So it could be improved in a future edition. I'm just about to try to write some comments to send in now but might send in more also depending on points made** (and others could also). There are individual threads on the two already: International Consensus Primer: http://forums.phoenixrising.me/index.php?posts/303639/ IACFS/ME Primer http://forums.phoenixrising.me/index.php?threads/me-cfs-primer-for-clinical-practitioners.17476/ so what I'm particularly interested in are differences between the two. * I find it more interesting to discuss countries outside the UK (the UK which already has the NICE guidelines). But people can discuss what they like. ** I'm not taking on any responsibility to collate the feedback from this thread and pass it on as I doubt I'll personally agree with every single point raised so it's best for people themselves to submit their own points to do them justice.
