It almost goes without saying that alternative practitioners contribute importantly to the ‘sea of misinformation’ about alternative medicine. Again, I could write books about this subject but have to refrain myself and therefore will merely put quick spotlights on several types of practitioners, mostly drawing from my own research on these subjects.
A survey of more than 9000 patients of U.K. non-medically trained acupuncturists showed that a considerable number had received advice from their therapists about prescribed medicines. Since these acupuncturists hold no medical qualifications, they are not qualified to issue such advice. It is therefore clear to me that the advice given is likely to be misleading. In 2000, we directly asked the U.K. acupuncturists’ advice about electro-acupuncture treatment for smoking cessation, a treatment which we previously had identified to be ineffective. The advice we received was frequently not based on current best evidence and some of it also raised serious safety concerns (Schmidt, K., & Ernst, E. Internet advice by acupuncturists—a risk factor for cardiovascular patients? Perfusion,2002, 15: 44-50. Article not Medline-listed).
Many chiropractors from the UK and other countries make unsustainable therapeutic claims on their websites. In 2002, at the height of the ‘‘MMR scare’’ in Britain, we conducted a study revealing that a sizable proportion of U.K. chiropractors advised mothers against having the measles-mumps-rubella (MMR) jab for their children. A survey of the U.K. chiropractors demonstrated that an alarming percentage of the U.K. chiropractors fail to provide advice about the risks of spinal manipulation before commencing treatment. As these risks are, in fact, considerable, this behaviour amounts to misinformation and is an obvious violation of medical ethics.
With osteopaths, it is a very similar story; the main difference is that there are far less investigations than for chiropractors. This may be due to the fact that, in the US, osteopaths are not alternative but conventional clinicians with much the same training and skills as proper doctors. But in Europe, they are strictly alternative and make as many bogus claims as chiropractors. Systematic investigations are rare, but I only need to remind us of my recent blog-post where I pointed out that:
Most osteopaths treat children for a wide range of conditions and claim that their interventions are helpful. They believe that children are prone to structural problems which can be corrected by their interventions. Here is an example from just one of the numerous promotional websites on this topic:
STRUCTURAL PROBLEMS, such as those affecting the proper mobility and function of the body’s framework, can lead to a range of problems. These may include:
- Postural – such as scoliosis
- Respiratory – such as asthma
- Manifestations of brain injury – such as cerebral palsy and spasticity
- Developmental – with delayed physical or intellectual progress, perhaps triggering learning behaviour difficulties
- Infections – such as ear and throat infections or urinary disturbances, which may be recurrent.
OSTEOPATHY can assist in the prevention of health problems, helping children to make a smooth transition into normal, healthy adult life.
Encouraging evidence exists for some specific herbs in the treatment of some specific conditions. Yet, virtually no good evidence exists to suggest that the prescriptions of individualized herbal mixtures by traditional herbalists across the globe generate more good than harm. Despite this lack of evidence, herbalists do not seem to offer this information voluntarily to his or her patients. When we directly asked the UK herbalists for advice on a clinical case, we found that it was ‘‘misleading at best and dangerous at worst’’ . In other words, herbalists misinform their patients and the public about the value of their treatments.
Many non-medically trained homeopaths advise their clients against the immunization of children. Instead, these practitioners often recommend using ‘‘homeopathic vaccinations’’ for which no good evidence exists. For instance, the vice-chair of the board of directors of ‘‘The Society of Homeopaths’’ had a site with the following statements: ‘‘Homeopathic alternatives to children’s immunisation are now available.’’ ‘‘Our clinic offers alternative immunisation programmes for the whole family.’’ Such statements amounts to misinformation which puts children’s health at risk.
Other alternative practitioners
I have chosen the above-listed professions almost at random and could have selected any other type as well. Arguably, all alternative practitioners who employ unproven treatments – and that must be the vast majority – misinform their patients to some extend. The only way to avoid this is to say: ‘look, I am going to give you a therapy for which there is no good evidence – I hope you don’t mind’. If they did that, they would be out of business in a flash. It follows, I think, that being in business is tantamount to misleading patients.
And there is, of course, another way of misinforming patients which is often forgotten yet very important: withholding essential information. In all of health care, informed consent is a ‘sine qua non’. Alternative practitioners very rarely obtain informed consent from their patients. The reason seems obvious (see above). I would argue that not informing people when they should be informed is a form of misinformation.
In this context, it is worth mentioning an investigation we did in 2009: We obtained the ethical codes of the following bodies: Association of Naturopathic Practitioners, Association of Traditional Chinese Medicine (UK), Ayurvedic Practitioners Association, British Acupuncture Council, Complementary and Natural Healthcare Council, European Herbal Practitioners Association, General Chiropractic Council, General Osteopathic Council, General Regulatory Council for Complementary Therapies, National Institute of Medical Herbalists, Register of Chinese Herbal Medicine, Society of Homeopaths, UK Healers, Unified Register of Herbal Practitioners. We then extracted the statements from these codes referring to evidence-based practice (EBP). The results showed that only the General Chiropractic Council, the General Osteopathic Council and the General Regulatory Council for Complementary Therapies oblige their members to adopt EBP.
It seems that misinformation is an alternative practitioner’s daily bread. Without it, alternative therapists would need to confine their practice to the few treatments/conditions for which the evidence is positive. If they ever followed this strategy, they would hardly be able to earn a living.
Where can someone turn to who wants reliable information on alternative medicine? Many consumers and patients who ask themselves this question might already be somewhat weary of the Internet; everybody should by now know that websites can be dangerously misleading and usually commercially driven. What about books then? People still tend to trust books; they are written by experts, published by responsible enterprises, and sold through respectable outlets. Surely we can trust books, or can’t we?
The first thing that strikes you when you look into the subject is the fact that there are thousands of books on alternative medicine. You only need to visit a major book shop in your high street and admire the rows and rows of these volumes. Since many years, I have been evaluating such volumes, for instance, for our journal FACT where we regularly publish reviews of new material. Through this and other work, I have gained the impression, that most of these books are not worth the paper they are printed on and constitute a major contributor to the misinformation bombarding the consumer in this area. But that was just an impression, hard data would be better.
In 1998, we assessed for the first time the quality of books on alternative medicine ( Int J Risk Safety Med 1998, 11: 209-215. [For some reason, this article is not Medline-listed]). We chose a random sample of 6 such books all published in 1997, and we assessed their contents according to pre-defined criteria. The findings were sobering: the advice given in these volumes was frequently misleading, not based on good evidence and often inaccurate. If followed, it would have caused significant harm to patients.
In 2006, we conducted a similar investigation which we then reported in the first and second editions of our book THE DESKTOP GUIDE TO COMPLEMENTARY AND ALTERNATIVE MEDICINE. This time, we selected 7 best-sellers in alternative medicine and scrutinised them in much the same way. What we found was revealing. Almost every treatment seemed to be recommended for almost every condition. There was no agreement between the different books which therapy might be effective for which condition. Some treatments were even named as indications for a certain condition, while, in other books, they were listed as contra-indications for the same problem. A bewildering plethora of treatments was recommended for most conditions, for instance:
- addictions: 120 different treatments
- arthritis: 131 different treatments
- asthma: 119 different treatments
- cancer: 133 different treatments
- etc. etc.
This experience, which we published as a chapter in our book entitled AN EPITAPH TO OPINION-BASED MEDICINE, confirmed our suspicion that books on alternative medicine are a major contributor to the ‘sea of misinformation’ in this area – and, as they are read by many people, a significant risk factor to public health.
Why do publishers allow such rubbish to be printed? Why do so many authors spend their time misleading the public with their dangerous half-knowledge? Why do consumers buy such overtly uncritical nonsense? I do not know the answers, I must admit. But I know that books of this nature do a disservice to everyone involved, including the few respectable aspect of alternative medicine which might actually exist.
Has the situation changed since 2006? We cannot be sure; there is, to the best of my knowledge, no hard data; and nobody has repeated our investigations. But my impression from regularly reviewing new books for FACT and other journals is far from encouraging. I fear that our ‘epitaph to opinion-based medicine’ might have been a little premature.
Imagine: you consult your doctor and he says: “I am so sorry, but I have bad news: the tests have shown that you have cancer”. You go home and feel as though someone has hit you with a sledge hammer. You cry a lot and your thoughts go round in circles. A complete nightmare unfolds; you sometimes think you are dreaming but reality soon catches up with you.
A few days later, you have an appointment with the oncologist who explains the treatment plan. You feel there is no choice and you agree to it. After the first chemotherapy, you lose your hair, your well-being, your dignity, your control and your patience – time to investigate what else there is on offer. There must be an alternative!
By then lots of well-wishers will have mentioned to you that the conventional route is but one of many: there are, in fact, alternatives!!! You go on the internet and find not just a few, you find millions of website promoting hundreds of solutions – anything from diets to herbal remedies, from homeopathy to faith-healing. All are being promoted as cures for your cancer, and all are free of those nasty side-effects which make your life hell at the moment. You think “there is a choice after all”.
Who would not be tempted by these options advertised in the most glorious terms? Who would not begin to distrust the oncologists who kindly but firmly insist that ‘alternative cancer cures’ are bogus? Who would not want to get rid of the cancer and the side-effects in one genial master-stroke?
Cancer patients yearn for hope and are extremely vulnerable to such influences. I do not know a single one who, faced with the diagnosis and all it entails, has not looked at the ‘alternatives’. This is why it would be so very important that the websites informing patients and their carers convey accurate and responsible information. But do they?
One of our research projects at Exeter had been aimed at assessing the quality of the websites advising patients on alternative treatments for cancer. For this purpose, we evaluated a total of 32 sites which cancer patients were most likely to consult according to pre-defined criteria – in other words, we assessed the most frequented websites for cancer.
Our results were shocking: many of these sites were of poor quality and most of them recommended a plethora of unproven treatments for cancer, most frequently herbal remedies, diets and mind-body therapies. In our estimation, at least three of them were outright dangerous and had the potential to harm patients.
The level of misinformation in this area is sickening. Patients are being sold false hope by the truck-load. Yet they deserve better; they deserve impartial information on their illness and the best treatment for it – cancer patients especially so. What they get instead is a total disgrace: commercially driven lies about ‘treatments’ which are not just unproven but which would, if used as instructed, hasten their death. Some alternative therapies have potential for palliative and supporting care, BUT NONE OFFER A CURE OR A REDUCTION OF THE TUMOR BURDEN OR A CHANGE IN THE NATURAL HISTORY OF THE DISEASE.
Colonic irrigation is the alternative therapy of celebrities (and those who like to imitate them): they tend to use it for all sorts of ailments, predominantly for loosing weight. And it works! When they have paid for the session, they are relieved of some cash as well as of about half a kilo of body weight. By the time they wake up the next morning, the money is still gone, but the weight is back. This is a most effective method for getting rid of some £s, but NOT an effective way for shedding a few pounds.
Numerous synonyms for colonic irrigation exist, e.g. colonic treatment, colon cleansing, rectal irrigation, colon therapy, colon hydrotherapy, colonic. The treatment is based on the ancient but obsolete theory of ‘autointoxication’, i.e. the body is assumed to poison itself with, ‘autotoxins’ which, in turn, cause various illnesses. So, it is implausible and there is also no evidence to suggest it is effective. But this does not stop professional organisations to make claims which are good for business.
My analysis of the claims made by professional organisations of practitioners of colonic irrigation across the globe aimed at assessing the therapeutic claims made by these institutions. Six such organisations were identified, and the contents of their websites were studied. The results showed that all of the six organisations make therapeutic claims on their websites. Frequently mentioned themes are ‘detoxification’, normalisation of intestinal functions, treatment of inflammatory bowel diseases and body weight reduction. The claims are mostly confined to symptomatic improvements – but there are exceptions, e.g. prevention of bowel cancer or sorting out Irritable Bowel Syndrome ‘once and for all’ . Other therapeutic claims pertain to asthma, menstrual irregularities, circulatory disorders, skin problems, improvement in energy levels and no longer requiring pharmacotherapy. All these claims represent testable hypotheses.
The question therefore arises whether these hypotheses have been tested and, if so, what the results of such investigations suggest? The use of colonic irrigation by alternative practitioners for any indications is not supported by any sound evidence at all. There are simply no trials to show effectiveness. Even worse is the fact that, although touted as safe, colonic irrigation can lead to serious complications.
The conclusion is therefore simple: colonic irrigation is neither demonstrably effective nor safe, and the information supplied by its professional organisations is therefore a significant contributor to the sea of misinformation in the realm of alternative medicine.
The UK ‘Society of Homeopaths’ (SoH) is the largest professional organisation of UK non-doctor, so-called lay- homeopaths. On their website, the SoH made very specific claims about homeopathy; in particular, they listed conditions for which homeopathy had allegedly been proven to be effective. These claims have now thoroughly been debunked, and the evidence the SoH produced in support of their claims has been shown to be misleading, cherry-picked or misinterpreted.
I have no idea who conducted the above-named investigation and made a youtube video of it, but I think it is essentially correct and well worth watching. My own experiences with the SoH relate mainly to two encounters.
The first was a complaint I made about one of their high-ranking officers, Ralf Jeutter. He had been promotiong homeopathic vaccinations on his website (needless to stress, I think, that there is no evidence to support the notion that homeopathic vaccinations are effective). As I felt that the SoH dragged their feet pursuing my complaint, I had to send several reminders. Eventually, they considered it and concluded that Reuter had done nothing wrong. This, presumably, is the reason why, even today, he can state on his website that Homeopathy is used to help individuals in dealing better with kinds of infections such as leptospirosis, meningitis and cholera. All is fine, it seems as long as a disclaimer is added: Any information obtained here is not to be construed as medical OR legal advice. The decision to vaccinate and how you implement that decision is yours and yours alone. The evidence for the efficacy of homeopathic immunisation is ‘anecdotal’. That means it is based on individuals’ reports past and present.
My second encounter with the SoH relates to my 2010 analysis of the SoH code of ethics and their adherence to it. The code demanded that:
- ‘all speculative theories will be stated as such and clearly distinguished’
- ‘no advertising may be used which expressly or implicitly claims to cure named diseases’
- ‘Advertising shall not be false, fraudulent, misleading, deceptive, extravagant or sensational.’
Encouraged by these assurances, I decided to study the websites of some members of the SoH, and soon discovered numerous and very obvious violations of the above-mentioned imperatives. In an attempt to find the root of these transgressions, I scrutinised the SoH’s own website where I found a multitude violations on all levels of the SoH’s own code of ethics. Many of the violations related to claims which were not supported by evidence. In other words, the largest professional UK organisation of lay- homeopaths misled the public in several rather devious ways:
they pretended to adhere to a code of ethics which forbids members to mislead the public
SoH -members nevertheless did mislead the public in ways that public health at risk
and they did so not least because the SoH followed exactly the same strategy
thus the SoH violated its own code of ethics to the detriment of public health.
My analysis was conducted a while ago, and some might hope that the SoH has stopped systematically misleading the public. This hope, however, is harshly disappointed when you watch the brand-new video entitled TESTING HOMEOPATHY mentioned above. As the SoH is about to celebrate 35 years of wisdom, courage, knowledge and prosperity, I do wonder whether this should not be 35 years of dangerously misleading the public.
What do you think?
In my last post and several others before, I have stated that consumers are incessantly being mislead about the value of alternative medicine. This statement requires evidence, and I intend to provide it – not just in one post but in a series of posts following in fast succession.
I start with an investigation we did over a decade ago. Its primary aim was to determine which complementary therapies are believed by their respective representing UK professional organizations to be suited for which medical conditions.
For this purpose, we sent out 223 questionnaires to CAM organizations representing a single CAM therapy (yes, amazingly that many such institutions exist just in the UK!). They were asked to list the 15 conditions which they felt benefited most from their specific CAM therapy, as well as the 15 most important contra-indications, the typical costs of initial and any subsequent treatments and the average length of training required to become a fully qualified practitioner. The conditions and contra-indications quoted by responding CAM organizations were recorded and the top five of each were determined. Treatment costs and hours of training were expressed as ranges.
Only 66 questionnaires were returned. Taking undelivered questionnaires into account, the response rate was 34%. Two or more responses were received from CAM organizations representing twelve therapies: aromatherapy, Bach flower remedies, Bowen technique, chiropractic, homoeopathy, hypnotherapy, magnet therapy, massage, nutrition, reflexology, Reiki and yoga.
The top seven common conditions deemed to benefit from all twelve therapies, in order of frequency, were: stress/anxiety, headaches/migraine, back pain, respiratory problems (including asthma), insomnia, cardiovascular problems and musculoskeletal problems. It is perhaps important at this stage to point out that some of these conditions are serious, even life-threatening. Aromatherapy, Bach flower remedies, hypnotherapy, massage, nutrition, reflexology, Reiki and yoga were all recommended as suitable treatments for stress/anxiety. Aromatherapy, Bowen technique, chiropractic, hypnotherapy, massage, nutrition, reflexology, Reiki and yoga were all recommended for headache/migraine. Bowen technique, chiropractic, magnet therapy, massage, reflexology and yoga were recommended for back pain. None of the therapies cost more than £60 for an initial consultation and treatment. No correlation between length of training and treatment cost was noted.
I think, this article provides ample evidence to show that, at least in the UK, professional organisations of alternative medicine readily issue statements about the effectiveness of specific alternative therapies which are not supported by evidence. Several years later, Simon Singh noted that phenomenon in a Guardian-comment and wrote about the British Chiropractic Association “they happily promote bogus claims”. He was famously sued for libel but won the case. Simon had picked the BCA merely by chance. The frightening thought is that he could have targeted any other of the 66 organisations from our investigation: they all seem to promote bogus claims quite happily.
Several findings from our study stood out for being particularly worrying: according to the respective professional organisation, Bach Flower Remedies were deemed to be effective for cancer and AIDS, for instance. If their peers put out such irresponsible nonsense, we should not be amazed at the claims made by the practitioners. And if the practitioners tell such ‘tall tales’ to their clients, to journalists and to everyone else, how can we be amazed that we seem to be drowning in a sea of misinformation?
A single, tiny mosquito can make my life a misery. It can rob me of a night’s sleep and turn me into a frantic lunatic. But now there is a remedy that, according to its manufacturer, makes my mosquito-phobia a distant memory. Mosquito-maniacs like myself can finally breathe a sigh of relief!
According to the manufacturer’s web-site, Mozi-Q is formula to reduce the frequency of bites as well as the reactions that people have to bites. No more itching and big red bumps! No more smelly sprays or stinky coils…what a great ally for camping, golfing, hiking, biking. This could revolutionize the whole outdoor experience! Some of the product’s features include:
- It works within 30 minutes of taking it.
- There are no side effects.
- It works on other bugs aside from mosquitoes like ticks and head lice.
- Product can be taken every 3-5 hours starting right before you go outside.
- There are no contraindications.
- Homeopathic medicine is by definition non-toxic…
Mozi-Q is a formula containing five homeopathic remedies:
- Ledum palustre
- Urtica urens
They are in low C and D potencies, thereby acting at the physical level for their common indication, to reduce the frequency and severity of insect bites….
I am sure that most readers will, by now, ask themselves: is there any good evidence for these claims? The manufacturer’s site is pretty affirmative:
In the ’60s a homeopath by the name of HR. Trexler studied Staphysagria for its effectiveness at preventing mosquito bites. In a study of 421 subjects over a 4 year period, he found this remedy to be 90% effective…We have tested this remedy in our clinic over four mosquito seasons and found the response from the public confirmatory of Trexler’s findings.
Sounds great? Yes, but it turns out that the Trexler trial did not test the mixture contained in Mozi-Q at all; it used just one of its ingredients. Moreover, it seemed to have lacked a control group and therefore constitutes no reliable evidence. And the manufacturer’s own tests? I don’t know, they tell us nothing about them.
At this stage, the mosquito-phobe is disappointed. It seems to me that this product is not supported by sound evidence – more trick than treatment.
And why would this important? Because some people like me might lose a bit of sleep? No! It is important because mosquitos, ticks and other insects transmit diseases, some of which can be deadly. If someone claims that there is a preparation which protects us from insect-bites, some consumers will inevitably trust this claim. And this would not just be unfortunate; it could be life-threatening.
One thing that unites all (well, almost all, in my experience) proponents of alternative medicine is their intense dislike for BIG PHARMA. Essentially, they see this sector as:
- Driven by profit
- Employing unethical means to maximise profit
- Not caring for the needs of patients
- Attacking alternative medicine for fear of losing profit
And, of course, they claim that alternative medicine, LITTLE ALT MED, is fundamentally different from the cynically capitalist, malign BIG PHARMA.
I have no intention to defend the ways of the pharmaceutical industry – neither on this blog nor anywhere else. This industry is usually responsible to their share-holders and that constellation can lead to excesses which are counter-productive to our needs, to put it mildly. However, what I will question is the notion that LITTLE ALT MED is fundamentally different from BIG PHARMA.
We all have to make a living; to some extend at least we are therefore all driven by our desire to earn money. In alternative medicine, there are certainly not as many mega-enterprises as in the pharmaceutical industry but nobody can deny that many sizable firms exist which make a profit selling alternative remedies of one type or another.
And those parts of alternative medicine which are not into the sale of remedies, you may well ask – think of acupuncture, for instance. Well, those therapists are not exempt either from the need to make a living. Sure, this is on a different scale from BIG PHARMA, but it constitutes still a need for profit. If we multiply the relatively small sums involved by the vast number of therapists, the grand total of LITTLE ALT MED might approach similar orders of magnitude as that of BIG PHARMA.
Ok, but the alternative sector would not employ unethical means for securing or maximising profits! Wrong again, I am afraid.
My 20 years of experience of LITTLE ALT MED have let me witness several incidents which I would not hesitate to call unethical. One of the most recent and least pleasant, from my point of view, was the discovery that several German homeopathic manufacturers had given money to a ‘journalist’ who used these funds to systematically defame me.
What about the charge that BIG PHARMA does not care for the suffering patient? LITTLE ALT MED would never do that!!! Sadly this is a myth too.
Alternative practitioners and their organisations make a plethora of therapeutic claims which are not substantiated. Who would deny that misleading patients into making wrong health care decisions is not the opposite from ‘caring’? What seems even worse, in my view, is the behaviour that might follow the exposure of such behaviour. If someone is courageous enough to disclose the irresponsibility of bogus claims, he might be attacked or even taken to court by those who, in reality should be in the dock or, at least, do their utmost to get their house in order.
Finally, we have the notion of BIG PHARMA trying to suppress LITTLE ALT MED. I call this a myth too because I see absolutely no evidence for this rumour. Even those who circulate it can, when challenged, not produce any.
And, anyway, we all know how many of the big pharmaceutical firms buy into the alternative medicine market as soon as they see a commercially viable opportunity. Does that look like suppression?
So, what is the conclusion? BIG PHARMA can behave badly, no doubt, and when they do, I am as disgusted as the next man. However, LITTLE ALT MED also can behave badly – in fact, wherever there is money to be made, some people will behave badly some of the time.
Perhaps we should not judge an entire sector just by the bad actions of some of its members, but perhaps we should also consider whether or not it has done any good. Who would doubt that BIG PHARMA has helped to save lives – millions of lives?!
And now ask yourself: can we honestly say the same about LITTLE ALT MED?
Hot flushes are a big problem; they are not life-threatening, of course, but they do make life a misery for countless menopausal women. Hormone therapy is effective, but many women have gone off the idea since we know that hormone therapy might increase their risk of getting cancer and cardiovascular disease. So, what does work and is also risk-free? Acupuncture?
Together with researchers from Quebec, we wanted to determine whether acupuncture is effective for reducing hot flushes and for improving the quality of life of menopausal women. We decided to do this in form of a Cochrane review which was just published.
We searched 16 electronic databases in order to identify all relevant studies and included all RCTs comparing any type of acupuncture to no treatment/control or other treatments. Sixteen studies, with a total of 1155 women, were eligible for inclusion. Three review authors independently assessed trial eligibility and quality, and extracted data. We pooled data where appropriate.
Eight studies compared acupuncture versus sham acupuncture. No significant difference was found between the groups for hot flush frequency, but flushes were significantly less severe in the acupuncture group, with a small effect size. There was substantial heterogeneity for both these outcomes. In a post hoc sensitivity analysis excluding studies of women with breast cancer, heterogeneity was reduced to 0% for hot flush frequency and 34% for hot flush severity and there was no significant difference between the groups for either outcome. Three studies compared acupuncture with hormone therapy, and acupuncture turned out to be associated with significantly more frequent hot flushes. There was no significant difference between the groups for hot flush severity. One study compared electro-acupuncture with relaxation, and there was no significant difference between the groups for either hot flush frequency or hot flush severity. Four studies compared acupuncture with waiting list or no intervention. Traditional acupuncture was significantly more effective in reducing hot flush frequency, and was also significantly more effective in reducing hot flush severity. The effect size was moderate in both cases.
For quality of life measures, acupuncture was significantly less effective than HT, but traditional acupuncture was significantly more effective than no intervention. There was no significant difference between acupuncture and other comparators for quality of life. Data on adverse effects were lacking.
Our conclusion: We found insufficient evidence to determine whether acupuncture is effective for controlling menopausal vasomotor symptoms. When we compared acupuncture with sham acupuncture, there was no evidence of a significant difference in their effect on menopausal vasomotor symptoms. When we compared acupuncture with no treatment there appeared to be a benefit from acupuncture, but acupuncture appeared to be less effective than HT. These findings should be treated with great caution as the evidence was low or very low quality and the studies comparing acupuncture versus no treatment or HT were not controlled with sham acupuncture or placebo HT. Data on adverse effects were lacking.
I still have to meet an acupuncturist who is not convinced that acupuncture is not an effective treatment for hot flushes. You only need to go on the Internet to see the claims that are being made along those lines. Yet this review shows quite clearly that it is not better than placebo. It also demonstrates that studies which do suggest an effect do so because they fail to adequately control for a placebo response. This means that the benefit patients and therapists observe in routine clinical practice is not due to the acupuncture per se, but to the placebo-effect.
And what could be wrong with that? Quite a bit, is my answer; here are just 4 things that immediately spring into my mind:
1) Arguably, it is dishonest and unethical to use a placebo on ill patients in routine clinical practice and charge for it pretending it is a specific and effective treatment.
2) Placebo-effects are unreliable, small and usually of short duration.
3) In order to generate a placebo-effect, I don’t need a placebo-therapy; an effective one administered with compassion does that too (and generates specific effects on top of that).
4) Not all placebos are risk-free. Acupuncture, for instance, has been associated with serious complications.
The last point is interesting also in the context of our finding that the RCTs analysed failed to mention adverse-effects. This is a phenomenon we observe regularly in studies of alternative medicine: trialists tend to violate the most fundamental rules of research ethics by simply ignoring the need to report adverse-effects. In plain English, this is called ‘scientific misconduct’. Consequently, we find very little published evidence on this issue, and enthusiasts claim their treatment is risk-free, simply because no risks are being reported. Yet one wonders to what extend systematic under-reporting is the cause of that impression!
So, what about the legion of acupuncturists who earn a good part of their living by recommending to their patients acupuncture for hot flushes?
They may, of course, not know about the evidence which shows that it is not more than a placebo. Would this be ok then? No, emphatically no! All clinicians have a duty to be up to date regarding the scientific evidence in relation to the treatments they use. A therapist who does not abide by this fundamental rule of medical ethics is, in my view, a fraud. On the other hand, some acupuncturists might be well aware of the evidence and employ acupuncture nevertheless; after all, it brings good money! Well, I would say that such a therapist is a fraud too.
The NHS tells us that our “choices include more than just which GP or hospital to use. You also have choices about your treatment decisions…” In most other countries, similarly confusing statements about PATIENT CHOICE are being made almost on a daily basis, often by politicians who have more ambition to win votes than to understand the complex issues at hand. Consequently, patients and consumers might be forgiven to assume that PATIENT CHOICE means we are all invited to indulge in the therapy we happen to fancy, while society foots the bill. Certainly, proponents of alternative medicine are fond of the notion that the principle of PATIENT CHOICE provides a ‘carte blanche’ for everyone who wants it to have homeopathy, Reiki, Bach Flower Remedies, crystal healing, or other bogus treatments – paid for, of course, by the taxpayer.
Reality is, however, very different. Anyone who has actually tried to choose his/her hospital will know that this is far from easy. And deciding what treatment one might employ for this or that condition is even less straight forward. Choice, it turns out, is a big word, but often it is just that: a word.
Yet politicians love their new mantra of PATIENT CHOICE; it is politically correct as it might give the taxpayer the impression that he/she is firmly installed in the driving seat. Consequently PATIENT CHOICE has become a slogan that is used to score points in public debates but that, in fact, is frequently next to meaningless. More often than not, the illusion of being in control has to serve as a poor substitute for actually being in control.
To imply that patients should be able to choose their treatment has always struck me as a little naïve, particularly in the way this is often understood in the realm of alternative medicine. Imagine you have a serious condition, say cancer: after you have come over the shock of this diagnosis, you begin to read on the Internet and consider your options. Should you have surgery or faith healing, chemotherapy or homeopathy, radiotherapy or a little detox?
Clearly PATIENT CHOICE, as paid for by society, cannot be about choosing between a realistic option and an unrealistic one. It must be confined to treatments which have all been shown to be effective. Using scarce public funds for ineffective treatments is nothing short of unethical. If, for a certain condition, there happen to be 10 different, equally effective and safe options, we may indeed have a choice. Alas, this is not often the case. Often, there is just one effective treatment, and in such instances the only realistic choice is between accepting or rejecting it.
And, anyway, how would we know that 10 different treatments are equally effective and safe? After going on the Internet and reading a bit about them, we might convince ourselves that we know but, in fact, very few patients have sufficient knowledge for making complex decisions of this nature. We usually need an expert to help us. In other words, we require our doctor to guide us through this jungle of proven benefits and potential risks.
Once we accept this to be true, we have arrived at a reasonable concept of what PATIENT CHOICE really means in relation to deciding between two or more treatments: the principle of shared decision making. And this is a fundamentally different concept from the naïve view of those alternative medicine enthusiasts who promote the idea that PATIENT CHOICE opens the door to opting for any unproven or disproven pseudo-therapy.
To be meaningful, ethical and responsible, choice needs to be guided by sound evidence – if not, it degenerates into irresponsible arbitrariness, and health care deteriorates into some kind of Russian roulette. To claim, as some fans of alternative medicine do, that the principle of PATIENT CHOICE gives everyone the right to use unproven treatments at the expense of the taxpayer is pure nonsense. But some extreme proponents of quackery go even further; they claim that the discontinuation of payment for treatments that have been identified as ineffective amounts to a dangerous curtailment of patients’ rights. This, I think, is simply a cynical attempt to mislead the public for the selfish purpose of profit.
