Select Committee on Science and Technology Minutes of Evidence


Examination of Witnesses (Questions 40-56)

PROFESSOR MARTIN MARSHALL, PROFESSOR SALLY DAVIES, DR KEITH RIDGE AND MR ALAN BELL

22 NOVEMBER 2006

  Q40  Lord Colwyn: We hear, that levels of allergy have soared in recent years and that GPs, perhaps, do not have an ideal training and cannot always cope with it and specialists are few and far between. Having said that, I do want to put a word in for my own profession, that of dentists, because in fact I recall having a fairly comprehensive training on allergy and certainly continuing professional education. It is something that we have to be very careful with; dentists are providing more invasive treatments, and it is a problem that we have to be aware of. So patients tend to go to high street counters for their treatments. Is there any evidence that treatments of no particular value are being offered over the counter in high street shops?

  Dr Ridge: In terms of the tests that are available over the counter, the regulation of that, as you will see from the memorandum, is largely based on whether the product is a medicine or whether it is a medical device. For actual medicines, those that are classed as medicines—creams, and those types of things that are classed as medicines—those are regulated in the normal way. For pharmacy itself there are professional standards in place which are currently being revised as pharmacy undergoes, if you like, a revolution in terms of how care is provided on the high street, and a new regulatory framework for pharmacists should be with us next year in terms of professional regulation. For other professionals we are likely to bring forward regulation of acupuncturists and herbal medicine as soon as possible. We have also asked the Prince of Wales' Foundation for Integrated Health to develop voluntary self-regulation amongst a range of other currently unregulated professions. As far as pharmacy is concerned, can I say a word around pharmacists in terms of their training? The pharmacy undergraduate course contains elements on allergy and conditions associated with allergy. Allergy is also in postgraduate training which is well taken up. Therefore, I would expect a pharmacist, from a professional point of view, to be recommending medicines or medical devices which have a proven use.

  Q41  Lord Colwyn: I may be wrong but I recall that the prescribing of antihistamine had to be done on the script and now you can get it over the counter. Has that changed? That must make a lot of difference to the products that are available.

  Dr Ridge: Absolutely. There are a range of products, licensed medicines, which are available over the counter. I think in the memorandum there is a figure which states that about £60 million a year is spent on over-the-counter therapies associated with allergy.

  Q42  Lord Colwyn: Can I come back to the problem of the complementary therapies, because this is something of great interest to me. Of course, many of the complementary therapists are, actually, regulated (you mentioned the ones who are looking for regulation). Is there any evidence that treatment in a complementary way is harmful in any way?

  Dr Ridge: I am not aware of any evidence that it is harmful. I guess we could look further at that. However, homeopathy, for example, as I guess you will be aware, is a recognised system of medicine and regulation, and in fact we have just brought forward new regulations around homeopathy in terms of the requirement for products to satisfy a safety and quality test, and those regulations came in on 1 September this year.

  Q43  Lord Colwyn: The treatment of allergy is all about arming one's immune system. That is the aim of complementary therapies. I do not know if you would comment on that.

  Dr Ridge: In terms of whether complementary therapies cause any harm? Is that the question?

  Q44  Lord Colwyn: Yes.

  Dr Ridge: I am not aware that they cause any harm.

  Professor Marshall: May I just add to that? In terms of direct harm from complementary therapies, there is not a lot of evidence, but Professor Edzard Ernst's team in Exeter has done some interesting work looking at indirect consequences of using complementary therapies, particularly in terms of delayed diagnosis and delay in receiving evidence-based therapies. So there is some interesting evidence here but it is contested, I think it is fair to say.

  Lord Colwyn: I think it is very minor evidence on that.

  Q45  Lord May of Oxford: You must be aware that recently in the House of Lords, in the debate in fact sponsored by Lord Taverne on the regulations on the labelling of homeopathic medicines, a variety of people of expertise in various relevant walks of life—the kind of expertise you find in the House of Lords—voiced very strongly the belief that the regulations had confused anecdote with established canons of controlled scientific evidence in what was allowed on labelling. In the light of that, can we have confidence that if you are going to move to produce regulations for these alternative things they will be done with a bit more thought and rigour?

  Dr Ridge: As you may be aware, there are two existing reviews of healthcare professional regulation, at the moment. One is associated with the medical profession and one with non-medical professionals. Consultation on that has just finished and the principles associated with both of those reports, I would imagine, would apply to certainly the herbalists and the acupuncturists in terms of their statutory regulation forthcoming. As for the others, if it is a self-regulatory system then I would hope to see similar principles apply, but it is still a self-regulatory system.

  Q46  Lord Taverne: You will be aware that when it came to the homeopathic regulations introduced on 1 September concern was expressed by nearly all the professional societies—including the Royal Society, the Academy of Medical Sciences and the Pharmacological Society—that for the first time regulations were being introduced which allowed claims of efficacy to be made which were not scientifically tested. Is that something which is going to be part of future regulation or not? Some concern was expressed to us at the seminar which was held before we started hearing witnesses that there was some misdiagnosis or delayed diagnosis, and the Royal College of Pathologists seems to have expressed concern that the regulation of non-NHS clinics is not adequate and that misleading advice can be harmful and costly for patients. I hope these representations are being taken seriously, and that we are not going to resort to non-scientific approaches to medicine on something as important as allergies.

  Dr Ridge: You are right in terms of how the regulations are set up and in terms of their requirement or not to demonstrate efficacy. I think that you are right to be concerned. However, there is clearly a need for complementary therapies, and the regulation of the professionals associated with those, I think, is in the process of being enhanced.

  Q47  Lord Taverne: Enhanced but not in the way in which it was enhanced to promote the homeopathic industry in the recent regulations. I hope that the regulation will be based on scientific tests. Can we have an assurance on that one?

  Dr Ridge: I would need to go back and talk to people about that assurance. I am sure we will provide you with a note.

  Q48  Lord Broers: May I ask whether there have been studies of the effects of prolonged allergic disease and the consequences of that? It would seem to me that severe asthma puts great strains on one's heart. I am not an expert on this, I am an engineer, but it would seem rather obvious; I have watched people with sustained asthma and it seems to put great strain on their system, so anything that delays treatment would seem to be harmful.

  Professor Marshall: There is evidence that untreated asthma can lead to long-term lung disease. So there is certainly evidence about that. Whether there is evidence in other areas of allergy, I am not sure.

  Professor Davies: No, I am not sure. Of course, long-term bad lung disease can have an impact on the heart, but you go through the lung disease before you impact on the heart long term. There is evidence that we all recognise as clinicians, of the allergic skin conditions it can lead to, lichenification, thickening, and itching and unpleasantness. So we are all aware of long-term consequences. Have I seen a study that tells you the magnitude of that problem? No, but this is not my speciality area; I am a haematologist.

  Q49  Chairman: Dr Ridge, could I follow up on the line of questioning that was directed at you previously? If we look at the patients who go into their local chemist shop and ask to see the pharmacist because they have symptoms that they believe to be allergic in nature, what training does that pharmacist have to give the advice and recommendations that are given?

  Dr Ridge: Pharmacists now undergo a four-year training programme at undergraduate level. I have confirmed with the Royal Pharmaceutical Society of Great Britain, who are the regulators of the pharmacy profession, that the components of allergy and treatment are within the indicative curriculum at the undergraduate level. It is also within the pre-registration year. At postgraduate level, the Department of Health funds the Centre for Pharmacy Postgraduate Education based at the University of Manchester, and they provide a series of learning materials associated with allergy, and looking at the figures in terms of uptake it seems reasonable.

  Q50  Chairman: Do they have any input from the clinical experts in allergy?

  Dr Ridge: In terms of the Centre for Postgraduate Pharmacy Education and how those packs are constructed, yes, is the answer to your question. I think it is also worth mentioning that as roles change within pharmacy (and, for example, pharmacists with a special interest will be with us quite soon, clinical specialists associated with a particular speciality working alongside and within a network associated with specialists in a hospital environment), then I expect to see that those people will be accredited in terms of how their training will take place. That is a requirement.

  Q51  Chairman: It seems to me there is an enormous training load that is emerging in this session: training of the GPs, training of nurses and training of pharmacists. Yet that requires a body of specialist knowledge to be informing that training process otherwise you will have constant repetition of what was the level of knowledge at one time but without integrating all of the research and, indeed, being involved in modern clinical practice, that will eventually become increasingly out of date. So there is a concern, I think, about the number of specialist services and specialists that will be brought forward if they are going to undertake the amount of training that is going to be demanded of them with these changes you propose.

  Professor Davies: Perhaps I could give you some good news. As you will know through the UK Clinical Research Collaboration, we went through a process which acquired the name of Walport, from Mark Walport, of looking at the training of clinical academics and agreed with Modernising Medical Careers a schema for training clinical academics which would be clinical fellowships and clinical lectureships. We are, at the moment, looking at the bids from university/NHS partnerships for training these people and accrediting those training programmes. We have agreed 11 programmes in allergy, which is not insignificant.

  Q52  Chairman: That is not insignificant, and thank you for bringing some good news to the table, Professor Davies. Could I move back to government policy and just ask you how the policy is formed in terms of giving advice to patients? For example, if we take the report from the Committee on the Medical Effects of Air Pollutants, does the Department now advise the public that air pollution is an important factor in allergic disease?

  Mr Bell: If I may answer this one, obviously in any area of government policy we would want to be informed by the available evidence. We believe that having done the review of allergy services we have done a lot to provide evidence for further development of policy on allergy. Referring to the particular report from COMEAP, my understanding of it is that that report showed that exposure to air pollutants does not in itself cause asthma but it may produce a worsening of the symptoms. Our colleagues at Defra provide an air pollution service on behalf of the UK Government and the devolved administrations. That air pollution service for the public involves making hourly updates available to the public through the Internet, a freephone helpline and TV teletext, and those updates show the current levels of air pollution and air quality forecasts. Defra also issues hourly updates to the media and other subscribers. So there is that information which we make available to the public about the levels of air pollutants. There is also a free booklet which you can get through the Defra website, which was produced by Defra in collaboration with us and some other government departments, which will give you advice as a member of the public on what particular levels of air pollutants may mean for you and your health.

  Q53  Chairman: What about advice to pregnant and lactating mothers over diet?

  Mr Bell: I am not an expert on that area. I know the Department of Health has issued advice on that area. I think that may be something we would need to follow up in writing to you.

  Chairman: It would be helpful because there are questions over the evidence base for it and indeed, if it is no longer underpinned by the evidence base, whether it has been made quite clear that that advice should no longer be given to women who are pregnant or lactating.

  Q54  Viscount Simon: You talk about air pollution, which is a very, very wide term. By what is air being polluted?

  Mr Bell: I would have to look at the COMEAP report to narrow down which pollutants are being talked about. There are all sorts of different things in the air, and I would need to check what the details are and what the Government's air pollution service therefore gives you information on. I am sorry I cannot answer that.

  Q55  Chairman: Thank you. We are just about at the end of our questioning. I have one thing, but you may want to supply this as a supplementary later, and that is who is actually responsible for determining the coding with the disease codes? The coding issue emerged early in our questioning.

  Professor Marshall: A combination of Connecting for Health, and that is directly through the clinical lead for Connecting for Health, a gentleman called Michael Thick, and the Chief Medical Officer's team, and I would take direct responsibility for that. So it is a combination of the two of us.

  Q56  Chairman: Perhaps you might like to take away our concern about the current coding system. Is there anything else you would like to tell us about that you feel that, perhaps, you have not had a chance to explain adequately in the questions we have put to you?

  Professor Marshall: No, we are happy, thank you.

  Chairman: Can I thank you for coming. If there is anything else that comes to mind, please feel free to send it in and it will be published with your evidence. Thank you all for coming and giving evidence today.
