The problem as I see it is that it is right and proper that there should be some rules about who is eligible based on a common sense approach to expertise and yet this seems not to have worked in this context. Since there was a recognised problem with involving psychiatrists it looks as if psychiatrists were not invited. So there had to be invitations to physicians dealing with ME, since they at least would have first hand experience. And political correctness requires that other health care professions were represented. This of course may not be strictly rational, but inclusivity is the flavour of the era. It would have seemed logical to me to include some physicians from other specialities, as more disinterested, but goodness knows who would have volunteered.
With that remit I suspect they had hardly any applicants that fitted the requirements apart from lay members and maybe a few therapists. Clearly they had to re-advertise. I can imagine that hardly any physicians initially applied. In that context if a PACE author applies, on what grounds do you make them ineligible? Doing research in an area is not evidence of a biased view. And the quality of PACE is something that this committee has to decide, not something that is established fact a priori.
Charles and myself and probably the others are not NHS ME physicians. I am not even a registered medical practitioner now. We were ineligible, at least according to the rules as they stood.
