Chiropractors are notorious for their overuse and misuse of x-rays for non-specific back and neck pain as well as other conditions. A recent study from the US has shown that the rate of spine radiographs within 5 days of an initial patient visit to a chiropractor is 204 per 1000 new patient examinations. Considering that X-rays are not usually necessary for patients with non-specific back pain, such rates are far too high. Therefore, a team of US/Canadian researchers conducted a study to evaluate the impact of web-based dissemination of a diagnostic imaging guideline discouraging the use of spine x-rays among chiropractors.
They disseminated an imaging guideline online in April 2008. Administrative claims data were extracted between January 2006 and December 2010. Segmented regression analysis with autoregressive error was used to estimate the impact of guideline recommendations on the rate of spine x-rays. Sensitivity analysis considered the effect of two additional quality improvement strategies, a policy change and an education intervention.
The results show a significant change in the level of spine x-ray ordering weeks after introduction of the guidelines (-0.01; 95% confidence interval=-0.01, -0.002; p=.01), but no change in trend of the regression lines. The monthly mean rate of spine x-rays within 5 days of initial visit per new patient exams decreased by 10 per 1000, a 5.26% relative decrease after guideline dissemination.
The authors concluded that Web-based guideline dissemination was associated with an immediate reduction in spine x-ray claims. Sensitivity analysis suggests our results are robust. This passive strategy is likely cost-effective in a chiropractic network setting.
These findings are encouraging because they suggest that at least some chiropractors are capable of learning, even if this means altering their practice against their financial interests – after all, there is money to be earned with x-ray investigations! At the same time, the results indicate that, despite sound evidence, chiropractors still order far too many x-rays for non-specific back pain. I am not aware of any recent UK data on chiropractic x-ray usage, but judging from old evidence, it might be very high.
It would be interesting to know why chiropractors order spinal x-rays for patients with non-specific back pain or other conditions. A likely answer is that they need them for the diagnosis of spinal ‘subluxations’. To cite just one of thousands of chiropractors with the same opinion: spinography is a necessary part of the chiropractic examination. Detailed analysis of spinographic film and motion x-ray studies helps facilitate a specific and timely correction of vertebral subluxation by the Doctor of Chiropractic. The correction of a vertebral subluxation is called: Adjustment.
This, of course, merely highlights the futility of this practice: despite the fact that the concept is still deeply engrained in the teaching of chiropractic, ‘subluxation’ is a mystical entity or dogma which “is similar to the Santa Claus construct”, characterised by a “significant lack of evidence to fulfil the basic criteria of causation”. But even if chiropractic ‘subluxation’ were real, it would not be diagnosable with spinal x-ray investigations.
The inescapable conclusion from all this, I believe, is that the sooner chiropractors abandon their over-use of x-ray studies, the better for us all.
I have written about this subject before, and I probably will do so again. The reason for my insistence is simple: some homeopathy-fans’ attitude towards and advice about immunizations is, in my view, nothing short of a scandal. Here are excerpts from two articles published in the current issue of ‘HOMEOPATHY 4 EVERYONE’ which amply explain what I mean.
The first paper is by Alan Phillips, a leading U.S. vaccine rights attorney and self-declared fan of homeopathy. It goes through the usual arguments suggesting that immunizations are not effective, outright harmful and a vicious ploy to enrich the pharmaceutical industry at the cost of public health. Subsequently, the author gives advice as to how US citizens can avoid mandatory immunizations:
God bless homeopathy! A particularly wonderful example was in Cuba in the fall of 2008, when homeoprophylaxis was used in place of allopathic immunizations to respond to a leptospirosis outbreak. Two and a half million people were each given 2 doses of a remedy, and the results not only substantially exceeded prior experience with vaccines, it was about 1/15 the cost! And to the best of my knowledge, there are no serious adverse events with homeopathy as there are with virtually any widespread use of vaccines. The failure of our government health agencies to seize upon the Cuban and other homeoprophylaxis successes by aggressively pursuing further research in this area, and the incorporation of homeoprophylaxis into standard infectious disease control strategies, reveals a public health policy driven by something other than the best health interests of the members of our society.
With all of the problems in the allopathic world, and obvious safe and effective alternatives to immunizations that are being systematically ignored, it’s no wonder that a growing number of people are looking for ways to legally avoid immunization mandates. Ironically, vaccines are being required in greater and greater numbers for more and more people. The reason is simple: The federal government subsidizes vaccine research and development; state and federal governments mandate vaccines; state and federal governments purchase vaccines; and state and federal governments compensate those injured or killed by vaccines. So, for those who are able to throw ethics and morality out the window without a second thought, there’s a racket here offering profound profits, and a convenient vehicle for injecting who knows what into literally billions of people worldwide. The multi-billion dollar international vaccine industry is projected to grow at some 10-12% annually for the next several years…
So you’ve done your research, and you’ve decided that you’d like to postpone, or even forego some or all vaccines altogether. Can you do that? How do you do that? Well, it depends on your specific situation…
Fortunately, everywhere vaccines are mandated in the U.S., one or more exemptions are available…
Medical exemptions can be hard to get. They usually require the support of a medical doctor, and there are usually specific, narrow criteria that must be met to qualify… So, if you’re considering a medical exemption, make sure you find out first what qualifies for the exemption in your specific situation; and if you can get a doctor to support you for a qualifying reason, then pursuing a medical exemption may be an appropriate route to take.
Religious exemptions are probably the most commonly used exemption. What qualifies is a topic too lengthy for an article, but in brief, it doesn’t require membership in an organized religion, and it doesn’t matter what religion you belong to, if you do belong to one…
Philosophical exemptions, when available, are great in that they don’t require you to justify your beliefs or to state reasons. But states have been changing laws to make them harder to get… The long-held notion of a presumed net benefit from vaccines has been slowly undermined by medical science, though the medical authorities, increasingly controlled by the pharmaceutical industry, continue to actively suppress this reality to the best of their ability… However, in those religious exemption situations where you are required to state your beliefs, and where the authorities involved have authority to scrutinize your beliefs, it is highly advisable to seek out professional help from an experienced attorney…
The second article is by Fran Sheffield, a homeopath from NSW, who began her homeopathic studies after “seeing the benefits homeopathy brought to her vaccine-injured child”, and a founding member of ‘The Do No Harm Initiative Inc.’, a lobby group misinforming communities and governments about ‘homeopathic immunisation’:
Homeoprophylaxis has a remarkable record of safety – vaccines less so. From the homeopath’s point of view they are still associated with risks: the dose is too strong, they have toxic additives, and they’re given by inappropriate pathways.
Homeoprophylaxis has avoided these problems. It’s also versatile, inexpensive, quick to produce and easy to distribute.
Keeping these points in mind, I’ll return to Von Behring who went on to say:
“I am touching here upon a subject anathematized till very recently by medical penalty: but if I am to present these problems in historical illumination, dogmatic imprecations must not deter me”…
The same sentiments are true today – dogma and penalty must not be allowed to restrict information on homeoprophylaxis or deprive others of this safe, simple option. The time has come for all of us – governments and individuals – to take a closer look at homeoprophylaxis and how it relieves the burden of disease…
Future posts show what I did with the prophylactic information, why some were offended or upset, the inevitable backlash that followed, attempts at intimidation and suppression, what happens when a matter like this goes to court, what is lost when we don’t speak out about the truth, and what we should do for the future.
I think I will abstain from any comment; if I did, I would be in danger of being libellous. However, I do hope that my readers will post their opinions freely.
Continuing on the theme from my previous post, a website of a homeopath (and member of the UK ‘Society of Homeopaths’) caught my attention. In in it, Neil Spence makes a wide range of far-reaching statements. Because they seem rather typical of the claims made by homeopaths, I intent to scrutinize them in this post. For clarity, I put the (unaltered and unabbreviated) text from Neil Spence’s site in italics, while my own comments are in Roman print.
The holistic model of health says all disease comes from a disturbance in the vitality (life force) of the body. The energetic disturbance creates symptoms in the mind, the emotions and the physical body. Each patient has their own store of how this disturbance in vitality came about and each person has individual symptoms.
What is a ‘holistic model of health’, I wonder? Holism in health care means to treat patients as whole individuals which is a hallmark of any good health care; this means that all good medicine is holistic.
Holism and vitalism are two separate things entirely. Vitalism is the obsolete notion of a vital force or energy that determines our health. ‘Disturbances in vitality’ are not the cause of illness.
We will attempt, as far as possible, to treat the whole person and to change the conditions that created your susceptibility to cancer.
Much of the susceptibility to cancer is genetically determined and cannot be altered homeopathically.
Using Homeopathy to treat people with cancer
Homeopathic treatment can help someone with cancer. It can also be helpful for people who have a history of cancer in their family or have cared for a relative or friend with cancer. There are a number of methods of using homeopathic remedies to help people with cancer.
There is no good evidence that homeopathic remedies are effective for cancer patients or their carers.
Constitutional treatment: Treat the person who suffers the illness. A constitutional homeopathic remedy suits your nature as a person and its symptom picture reflects the unique expression of your symptoms. It can arouse the bodyʼs natural ability to heal itself and this can have profound benefits. It is appropriate if your vitality is strong.
There is no evidence that constitutional homeopathic treatments increase the body’s self-healing ability.
Stimulate the immune system to fight cancer: Remedies can be used to help the body fight the cancer, using specific homeopathic remedies called nosodes. A second treatment may be used to support the weakened organ. This method is most useful for people who are not using chemotherapy or radiotherapy.
There is no evidence that nosodes or other homeopathic remedies have any effect on the immune system ( – if they did, they would be contra-indicated for people suffering from auto-immune diseases).
Support the failing organs and the functions of the body that are not working: Remedies can be used to support weakened organs; to help with appetite; to help sleep and to treat sleep disturbances; to reduce the toxic symptoms; to help the body eliminate toxins. These treatments are helpful to people undergoing chemotherapy or radiotherapy.
For none of these claims is there good evidence; they are pure fantasy. The notion that homeopathy can help eliminate toxins is so wide-spread that it merits a further comment. It would be easy to measure such a detoxifying effect, but there is no evidence that it exists. Moreover, I would question whether, in the particular situation of a cancer patient on chemotherapy, a hastened elimination of the toxin (= chemotherapeutic agent) would be desirable; it would merely diminish the efficacy of the chemotherapy and reduce the chances of a cure.
Treat the pain: Homeopathic remedies can be very effective in aiding pain control. Remedies such as calendula can be effective in situations of intractable pain. If the cancer is at the terminal stage, remedies can be used to increase the quality of life. These remedies are palliative and can assist the patient keep mentally and emotionally alert so they can have quality time with loved ones.
Where is the evidence? Pain can obviously be a serious problem for cancer patients, and the notion that calendula in homeopathic dilutions reduces pain such that it significantly improves quality of life is laughable. Conventional medicine has powerful drugs to alleviate cancer pain but even they sometimes do not suffice to make patients pain-free.
Homeopathy in conjunction with other therapies
When a patient chooses to use chemotherapy or radiotherapy to treat their cancer the homeopath will prescribe remedies to support the body and ease the side-effects. Remedies can also be very useful after surgery to encourage the body to heal and allow greater mobility at an early stage.
Again no good evidence exists to support these claims – pure fantasy.
Other therapies can complement homeopathy but the homeopath will advise that you do not use every therapy just because they are available. It may be better to choose two or perhaps three main approaches to improving your health and ensure each one has positive effects that suit you very well.
Is he saying that cancer patients are best advised to listen to a homeopath rather than to their oncology-team? Is he encouraging them to not use all possible mainstream options available? If so, he is most irresponsible.
Each person will have different needs. It is always appropriate to change your diet. Nutritional and dietary advice is of the utmost importance to support the bodyʼs healing process. Cancer has many symptoms of disturbed metabolism and a poor diet has often contributed to the disturbance in the body that allowed the cancer to flourish. It is essential to remedy this situation. Nutritional advice puts you back in charge of your body; with good homeopathic treatments this provides the basis for improving your health.
Dietary advice can be useful and is therefore routinely provided by professionals who understand this subject much better than the average homeopath.
The thought that some cancer patients might be following such recommendations is most disturbing. Advice of this nature has doubtlessly the potential to significantly shorten the life and decrease the well-being of cancer patients. People who recommend treatments that clearly harm vulnerable patients are charlatans who should not be allowed to treat patients.
2013 has been an extremely busy year on this blog. We have had so many posts and comments that it is hard to decide which were the best, most important or most thought-provoking. The following selection is an entirely subjective and personal choice. I have copied the titles of the chosen posts and linked them to the original; in addition, I have selected a short conclusion from each post to provide an impression of its content so that, if interested, you can easily read the whole thing.
I don’t think anyone doubts that medicine needs improving. However, I do doubt that Charles’ vision of a “post-modern medicine” is the way to achieve improvement – in fact, I fear that it would lead us straight back to the dark ages.
So, what does this tiny investigation suggest? … I think it supports the hypothesis that research into chiropractic is not very active, nor high quality, nor does it address the most urgent questions.
The often-used and seemingly reasonable sentence “I don’t care how it works, as long as it is helpful” turns out to be a package of fallacies used to support the use of unproven treatments.
I think it is regrettable that the journal ‘Homeopathy’ has now lost the only editorial board member who had the ability to openly and repeatedly display a critical attitude about homeopathy – remember: without a critical attitude progress is unlikely!
For 20 years, I have tried my best to dispel these dangerous myths and fallacies. In doing so, I had to fight many tough battles (sometimes even with the people who should have protected me, e.g. my peers at Exeter university), and I have the scars to prove it. If, however, I did save just one life by conducting my research into the risks of alternative medicine and by writing about it, the effort was well worth it.
The most remarkable aspect is that the BCA seems to attempt to silence its own members regarding the controversy about the value of their treatments. Instead they proscribe answers (should I say doctrines?) of highly debatable accuracy for them, almost as though chiropractors were unable to speak for themselves. To me, this smells of cult-like behaviour, and is by no means indicative of a mature profession – despite their affirmations to the contrary.
To pretend that external evidence can be substituted by something else is erroneous and introduces double standards which are not acceptable – not because this would be against some bloodless principles of nit-picking academics, but because it would not be in the best interest of the patient. And, after all, the primary concern of EBM has to be the patient.
The conclusion of such considerations is, I fear, obvious: the value of and need for these two professions [chiropractors and osteopaths] should be re-assessed.
Unethical research of this nature should be prevented, and the existing mechanisms to achieve this aim must be strengthened.
It is time that AM investigators focus on real research answering important questions which advance our knowledge, that AM-journal editors stop publishing meaningless nonsense, and that decision-makers understand the difference between promotion dressed up as science and real research.
There are many other parallels between a cult and alternative medicine, I am sure. In my view, the most striking one must be the fact that any spark of cognitive dissonance in the cult-victim is being extinguished by highly effective and incessant flow of misinformation which often amounts to a form of brain-washing.
If a clinician practices evidence-based medicine, he/she cannot possibly practice homeopathy – the evidence shows that homeopathy is a placebo-therapy. So, here we have it: a competent homeopath has to be a contradiction in terms because either someone practices homeopathy or he/she practices evidence-based medicine. Doing both at the same time is simply not possible.
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.
I challenge my critics to answer this simple question: For how many alternative therapies is there a well-documented positive risk/benefit balance?
Some homeopaths, rather than admitting they are in the wrong, are prepared to dilute the truth until it might be hard for third parties to tell who is right and who is wrong. But however they may deny it, the truth is still the truth: I have been trained as a homeopath.
This is how pseudo-scientists make sure that the body of pseudo-evidence for their pseudo-treatments is growing at a steady pace.
Not only has the truth about the libel case been turned upside down, but also the evidence on chiropractic as a treatment for infant colic seems mysteriously improved.
I am sure that, in the future, we will hear much more about Charles’ indulgence in quackery; and, of course, we will hear more criticism of it.
This is the bizarre phenomenon that ‘Ernst’s law’ seems to capture quite well – and this is why I believe the ‘law’ is worth more than a laugh and a chuckle. In fact, ‘Ernst’s law’ might even describe the depressing reality of retrograde thinking in alternative medicine more accurately than most of us care to admit.
In my experience, true believers will not change their mind; I have never seen this happening. However, progress might nevertheless be made, if we managed to instil a more (self-) questioning rationality and scientific attitudes into the minds of the next generations. In other words, we need better education in science and more training of critical thinking during their formative years.
Yes, I am afraid the fight of many homeopaths against public health is active, incessant and often criminal. Of course, they do not for one second believe that they are doing anything wrong; on the contrary, they are convinced of their good intentions. As Bert Brecht once wrote, THE OPPOSITE OF GOOD IS NOT EVIL, BUT GOOD INTENTIONS
I am sure that many of my readers have sleepless night because they cannot think of a fitting Christmas present for their alternative therapist. I have given this increasingly acute problem some thought and come up with a few handy suggestions.
FOR THE REFLEXOLOGIST
Reflexologists believe that our organs are represented on the sole of our feet. By exerting pressure on locations which correspond to specific organs, they seek to influence the function of these organs. What the reflexologist therefore needs is an insole for her shoes that is deeply cushioned so that these sensitive points are well protected from unwanted exposure to strain. Without this protection, the reflexologist’s health might be in danger; imagine her crossing the street and inadvertently putting pressure on the liver or heart area. This would stimulate these organs and the unsuspecting therapist might suffer tachycardia or her liver might go into over-drive and metabolize drugs like warfarin way too fast, thus leaving her prone to suffer a blood clot.
FOR THE CHIROPRACTOR
Chiropractic was invented about 120 years ago when D.D. Palmer adjusted a subluxation in the neck of a deaf janitor who could then hear again. Chiropractors have ever since claimed that their adjustments free vital nerves that have been blocked by spinal subluxations. I suggest to give them a textbook of anatomy; there they can read up how the inner ear is connected to the brain via nerves which do not even pass via the spine but remain safely in the skull. I am sure the chiropractor will appreciate this news; it will make her think and she might even start doubting whether the rest of the gospel of Mr Palmer is correct.
FOR THE CRANIO-SACRAL THERAPIST
I suggest to give this practitioner an integral helmet for Christmas. Cranio-sacral therapy is based on the idea that the bones of the skull move ever so slightly and that these movements have a profound influence on our health. If that is true, the head of the therapist is in urgent need of complete protection from outside interference of any kind. Even a slight touch from a friend or spouse could have unforeseeable consequences. If she does not already have one, she needs a motorcycle-helmet and must wear it at all times.
FOR THE HOMEOPATH
Homeopaths dilute their remedies endlessly and are convinced that this process which they call ‘potentiation’ renders their remedies not weaker but stronger. The most treasured remedies contain nothing at all. To make a homeopath truly happy, one therefore should give her a nicely wrapped box that contains nothing. Make sure that the box once contained something really nice; like this it will have a powerful memory of its past content which is what homeopaths are after. I am sure she will be overwhelmed by this generosity and enjoy the present for years to come.
FOR THE REIKI MASTER
Reiki is the art of channelling healing energy via the hands of the therapist into a patient’s body. Reiki masters are unusually skilled and have energy-filled hands. When they are not in action, their energy would leak uselessly from their hand; and when they need it for their good work, they may have run empty. This disastrous situation would lead to the ineffectiveness of the otherwise useful intervention. I think that a fully insulated pair of gloves could prevent this situation. My suggestion therefore is to give the Reiki master a pair of solid skiing gloves which have been fitted with insulating material and to advise the master to wear them when not doing her healing.
FOR THE TRADITIONAL CHINESE ACUPUNCTURIST
By far the most common serious complication of acupuncture is a pneumothorax; it happens when an acupuncture needle punctures a lung and means that the patient is in a spot of trouble. If the acupuncturist happens to insert needles on both sides of the thorax, both lungs can be punctured, and then the patient is in a lot of trouble. As anyone can call herself an acupuncturist, some seem to have no idea where the lungs are and are blissfully unaware that their needles can penetrate into vital organs. I think the ideal gift for such acupuncturists might be an atlas of anatomy where they can see with their own eyes what damage a little misplaced needle can cause.
FOR THE HERBALIST
Herbalists tend to promote the idea that, because herbal extracts are natural, they are necessarily safe. The most fitting present for such a therapist might be a textbook of toxicology. There she will find that some of the most powerful poisons come from the plant kingdom. It might not be an insight that she likes, but it just could save some patients from getting hurt.
FOR THE COLONIC IRRIGATIONIST
Colonic irrigation involves pouring lots of water into the part of the body where the sun doesn’t shine in order to detoxify the patient. As the notion of such ‘detox’ is entirely bonkers, I suggest that these therapists could diversify into more serious areas of medicine. Give them a tin of instant coffee for Christmas, and they will be able to claim to treat cancer. Coffee-enemas are a popular alternative treatment for cancer, and I am sure the therapist will be thankful for this opportunity to enlarge her business.
This list could be extended, of course, but I think I will stop here and give my readers the occasion to contribute their own suggestions; surely your ideas are better than mine. So, please put them into your short comments below.
Even relatively well-informed people tend to think that homeopathy might be quirky and useless but, so what, it cannot do any harm. This is perhaps true for the homeopathic remedies but it does certainly not apply to the homeopaths. As soon as there is a public health problem, homeopaths claim that their approach offers a solution – never mind the evidence to the contrary. Just look at what they presently try to sell us in terms of cold and flu treatments!
The often criminal fight of homeopaths against public health is nowhere clearer than with their never-ending propaganda against the most successful public health measure in the history of medicine, immunisation. Some professional organisations of homeopathy have issued politically correct statements about this and thus feel they are out of the firing line. But, as far as I can see, most homeopaths are against vaccinations. Their arguments are wilfully misguided; here are just a few examples:
- It is well known that measles is an important development milestone in the life and maturing processes in children. Why would anybody want to stop or delay the maturation processes of children and of their immune systems?
- Homoeopathy offers an option for disease prevention and cure. There is scientific evidence in favour of homoeopathy for prevention of diseases.
- Seek out homeopathic, osteopathic, naturopathic, or Chinese medical constitutional treatment to boost your child’s immune system and help them be as healthy as they can be.
- If your children do get sick, use homeopathy to help their immune system get over it. Homeopathy is very effective in epidemics of acute illness. Either see a homeopath, buy a book on homeopathic acute care, or take a class on acute homeopathic prescribing.
- It is possible to prevent post-vaccination damage by giving the homeopathic dilution of the vaccine shortly before and after the vaccination in the C200 dilution.
- there are many recorded cases of people making dramatic recoveries with homeopathic medicines following a bad reaction to a vaccination. Expert advice from a registered homeopath is usually required.
- As you would keep your children away from toxic chemicals in the environment as much as possible, inform yourself about the toxicity of the solutions that are being injected into their bloodstream. It’s up to you to find the information: no one loves your children the way you do.
If you think I cherry-picked these quotes, you are mistaken. I simply used the citations as they appeared on my computer screen after a simple Google search. You might try this yourself because there are hundreds, if not thousands more to be discovered.
A typical and interesting example of a homeopathic anti-vaccinationist is Oksana Frolov, D.Hom. graduate of Saint Petersburg, Russia, I.P.Pavlov State Medical University, General Medicine, and graduate of Los Angeles School of Homeopathy. She states that, although I do hold a medical degree, I am not a licensed medical health provider in the United States. As a homeopathic practitioner, I will provide you with the treatment which is alternative or complementary to healing arts that are licensed by the State of California. On her blog, she provides detailed advice for people who might be uncertain whether to vaccinate their children: immunisation… can cause some very serious side effects including permanent brain damage, epilepsy, autism, and mental retardation. With so many vaccinations being required, doctors often have to administer several shots at a time, which can often result in a disaster. Vaccines, along with the elements that are supposed to create the antibodies, also contain mercury, aluminum, formaldehyde, animal tissue, animal blood, human cell from aborted babies, potatoes, yeast, lactose, phenol, antibiotics and unrelated species of germs that inadvertently get into the vaccines. Do you really want all this to be injected into your child just to prevent him or her from having a chicken pox? Vaccines are said to work by stimulating the body to produce antibodies, which are supposed to protect us from an invasion of harmful germs. Childhood diseases, such as measles, mumps, rubella and chicken pox, affect the immune system in a way that makes most people immune to them for the rest of their lives. Vaccinations, on the other hand, create an artificial immunity that wears off and allows the person to catch the disease later in life….
Homeopathy has proved to be very effective in treatment of childhood diseases, as well as other infections. From its earliest days, homeopathy has been able to treat epidemic disease, such as cholera, typhus, yellow fever, and diphtheria, with a substantial rate of success, when compared to conventional treatments.
Doctors who practice homeopathy usually claim that only non-medically qualified homeopaths hold such deranged views. Dr Frolov shows us that this assumption is clearly not true. In my experience, most homeopaths, medical or not, advise their patients against immunizations or are at least very cagey about this subject in order to raise doubts in concerned parents. Professional organisations of homeopaths usually hide behind some powerless statement in favour of informed choice; yet they must be well-aware that many of their members fail to abide by it. And what do they do about it? Nothing!
Yes, I am afraid the fight of many homeopaths against public health is active, incessant and often criminal. Of course, they do not for one second believe that they are doing anything wrong; on the contrary, they are convinced of their good intentions. As Bert Brecht once wrote, THE OPPOSITE OF GOOD IS NOT EVIL, BUT GOOD INTENTIONS.
Yes, it is unlikely but true! I once was the hero of the world of energy healing, albeit for a short period only. An amusing story, I hope you agree.
Back in the late 1990s, we had decided to run two trials in this area. One of them was to test the efficacy of distant healing for the removal of ordinary warts, common viral infections of the skin which are quite harmless and usually disappear spontaneously. We had designed a rigorous study, obtained ethics approval and were in the midst of recruiting patients, when I suggested I could be the trial’s first participant, as I had noticed a tiny wart on my left foot. As patient-recruitment was sluggish at that stage, my co-workers consulted the protocol to check whether it might prevent me from taking part in my own trial. They came back with the good news that, as I was not involved in the running of the study, there was no reason for me to be excluded.
The next day, they ‘processed’ me like all the other wart sufferers of our investigation. My wart was measured, photographed and documented. A sealed envelope with my trial number was opened (in my absence, of course) by one of the trialists to see whether I would be in the experimental or the placebo group. The former patients were to receive ‘distant healing’ from a group of 10 experienced healers who had volunteered and felt confident to be able to cure warts. All they needed was a few details about each patients, they had confirmed. The placebo group received no such intervention. ‘Blinding’ the patient was easy in this trial; since they were not themselves involved in any healing-action, they could not know whether they were in the placebo or the verum group.
The treatment period lasted for several weeks during which time my wart was re-evaluated in regular intervals. When I had completed the study, final measurements were done, and I was told that I had been the recipient of ‘healing energy’ from the 10 healers during the past weeks. Not that I had felt any of it, and not that my wart had noticed it either: it was still there, completely unchanged.
I remember not being all that surprised…until, the next morning, when I noticed that my wart had disappeared! Gone without a trace!
Of course, I told my co-workers who were quite excited, re-photographed the spot where the wart had been and consulted the study protocol to determine what had to be done next. It turned out that we had made no provisions for events that might occur after the treatment period.
But somehow, this did not feel right, we all thought. So we decided to make a post-hoc addendum to our protocol which stipulated that all participants of our trial would be asked a few days after the end of the treatment whether any changes to their warts had been noted.
Meanwhile the healers had got wind of the professorial wart’s disappearance. They were delighted and quickly told other colleagues. In no time at all, the world of ‘distant healing’ had agreed that warts often reacted to their intervention with a slight delay – and they were pleased to hear that we had duly amended our protocol to adequately capture this important phenomenon. My ‘honest’ and ‘courageous’ action of acknowledging and documenting the disappearance of my wart was praised, and it was assumed that I was about to prove the efficacy of distant healing.
And that’s how I became their ‘hero’ – the sceptical professor who had now seen the light with his own eyes and experienced on his own body the incredible power of their ‘healing energy’.
Incredible it remained though: I was the only trial participant who lost his wart in this way. When we published this study, we concluded: Distant healing from experienced healers had no effect on the number or size of patients’ warts.
AND THAT’S WHEN I STOPPED BEING THEIR ‘HERO’.
There are numerous types and styles of acupuncture, and the discussion whether one is better than the other has been long, tedious and frustrating. Traditional acupuncturists, for instance, individualise their approach according to their findings of pulse and tongue diagnoses as well as other non-validated diagnostic criteria. Western acupuncturists, by contrast, tend to use formula or standardised treatments according to conventional diagnoses.
This study aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice of a Chinese-born medical doctor trained in both western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups who received either standardized acupuncture or individualized acupuncture. 10 to 15 treatments based on individual symptoms were given with two treatments per week.
The main outcome measure was the area under the curve (AUC) summarizing eight weeks of daily rated pain severity measured with a visual analogue scale. No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7; standardized acupuncture 1482.9; group difference, 285.8).
The authors concluded that individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain.
But perhaps it matters whether the acupuncturist is thoroughly trained or has just picked up his/her skills during a weekend course? I am afraid not: this analysis of a total of 4,084 patients with chronic headache, lower back pain or arthritic pain treated by 1,838 acupuncturists suggested otherwise. There were no differences in success for patients treated by physicians passing through shorter (A diploma) or longer (B diploma) training courses in acupuncture.
But these are just one single trial and one post-hoc analysis of another study which, by definition, cannot be fully definitive. Fortunately, we have more evidence based on much larger numbers. This brand-new meta-analysis aimed to evaluate whether there are characteristics of acupuncture or acupuncturists that are associated with better or worse outcomes.
An existing dataset, developed by the Acupuncture Trialists’ Collaboration, included 29 trials of acupuncture for chronic pain with individual data involving 17,922 patients. The available data on characteristics of acupuncture included style of acupuncture, point prescription, location of needles, use of electrical stimulation and moxibustion, number, frequency and duration of sessions, number of needles used and acupuncturist experience. Random-effects meta-regression was used to test the effect of each characteristic on the main effect estimate of pain. Where sufficient patient-level data were available, patient-level analyses were conducted.
When comparing acupuncture to sham controls, there was little evidence that the effects of acupuncture on pain were modified by any of the acupuncture characteristics evaluated, including style of acupuncture, the number or placement of needles, the number, frequency or duration of sessions, patient-practitioner interactions and the experience of the acupuncturist. When comparing acupuncture to non-acupuncture controls, there was little evidence that these characteristics modified the effect of acupuncture, except better pain outcomes were observed when more needles were used and, from patient level analysis involving a sub-set of 5 trials, when a higher number of acupuncture treatment sessions were provided.
The authors of this meta-analysis concluded that there was little evidence that different characteristics of acupuncture or acupuncturists modified the effect of treatment on pain outcomes. Increased number of needles and more sessions appear to be associated with better outcomes when comparing acupuncture to non-acupuncture controls, suggesting that dose is important. Potential confounders include differences in control group and sample size between trials. Trials to evaluate potentially small differences in outcome associated with different acupuncture characteristics are likely to require large sample sizes.
My reading of these collective findings is that it does not matter which type of acupuncture you use nor who uses it; the clinical effects are similar regardless of the most obvious potential determinants. Hardly surprising! In fact, one would expect such results, if one considered that acupuncture is a placebo-treatment.
A recent interview on alternative medicine for the German magazine DER SPIEGEL prompted well over 500 comments; even though, in the interview, I covered numerous alternative therapies, the discussion that followed focussed almost entirely on homeopathy. Yet again, many of the comments provided a reminder of the quasi-religious faith many people have in homeopathy.
There can, of course, be dozens of reasons for such strong convictions. Yet, in my experience, some seem to be more prevalent and important than others. During my last two decades in researching homeopathy, I think, I have identified several of the most important ones. In this post, I try to outline a typical sequence of events that eventually leads to a faith in homeopathy which is utterly immune to fact and reason.
The starting point of this journey towards homeopathy-worship is usually an impressive personal experience which is often akin to an epiphany (defined as a moment of sudden and great revelation or realization). I have met hundreds of advocates of homeopathy, and those who talk about this sort of thing invariably offer impressive stories about how they metamorphosed from being a ‘sceptic’ (yes, it is truly phenomenal how many believers insist that they started out as sceptics) into someone who was completely bowled over by homeopathy, and how that ‘moment of great revelation’ changed the rest of their lives. Very often, this ‘Saulus-Paulus conversion’ relates to that person’s own (or a close friend’s) illness which allegedly was cured by homeopathy.
Rachel Roberts, chief executive of the Homeopathy Research Institute, provides as good an example of this sort of epiphany as anyone; in an article in THE GUARDIAN, she described her conversion to homeopathy with the following words:
I was a dedicated scientist about to begin a PhD in neuroscience when, out of the blue, homeopathy bit me on the proverbial bottom.
Science had been my passion since I began studying biology with Mr Hopkinson at the age of 11, and by the age of 21, when I attended the dinner party that altered the course of my life, I had still barely heard of it. The idea that I would one day become a homeopath would have seemed ludicrous.
That turning point is etched in my mind. A woman I’d known my entire life told me that a homeopath had successfully treated her when many months of conventional treatment had failed. As a sceptic, I scoffed, but was nonetheless a little intrigued.
She confessed that despite thinking homeopathy was a load of rubbish, she’d finally agreed to an appointment, to stop her daughter nagging. But she was genuinely shocked to find that, after one little pill, within days she felt significantly better. A second tablet, she said, “saw it off completely”.
I admit I ruined that dinner party. I interrogated her about every detail of her diagnosis, previous treatment, time scales, the lot. I thought it through logically – she was intelligent, she wasn’t lying, she had no previous inclination towards alternative medicine, and her reluctance would have diminished any placebo effect.
Scientists are supposed to make unprejudiced observations, then draw conclusions. As I thought about this, I was left with the highly uncomfortable conclusion that homeopathy appeared to have worked. I had to find out more.
So, I started reading about homeopathy, and what I discovered shifted my world for ever. I became convinced enough to hand my coveted PhD studentship over to my best friend and sign on for a three-year, full-time homeopathy training course.
Now, as an experienced homeopath, it is “science” that is biting me on the bottom. I know homeopathy works…
As I said, I have heard many strikingly similar accounts. Some of these tales seem a little too tall to be true and might be a trifle exaggerated, but the consistency of the picture that emerges from all of these stories is nevertheless extraordinary: people get started on a single anecdote which they are prepared to experience as an epiphanic turn-around. Subsequently, they are on a mission of confirming their new-found belief over and over again, until they become undoubting disciples for life.
So what? you might ask. But I do think this epiphany-like event at the outset of a homeopathic career is significant. In no other area of health care does the initial anecdote regularly play such a prominent role. People do not become believers in aspirin, for instance, on the basis of a ‘moment of great revelation’, they may take it because of the evidence. And, if there is a discrepancy between the external evidence and their own experience, as with homeopathy, most people would start to reflect: What other explanations exist to rationalise the anecdote? Invariably, there are many (placebo, natural history of the condition, concomitant events etc.).
Epiphany-stuck believers spends much time and effort to actively look for similar stories that seem to confirm the initial anecdote. They might, for instance, recommend or administer or prescribe homeopathy to others, many of whom would report positive outcomes. At the same time, all anecdotes that do not happen to fit the belief are brushed aside, forgotten, supressed, belittled, decried etc. This process leads to confirmation after confirmation after confirmation – and gradually builds up to what proponents of homeopathy would call ‘years of experience’. And ‘years of experience’ can, of course, not be wrong!
Again, believers neglect to question, doubt and rationalise their own perceptions. They ignore the fact that years of experience might just be little more than a suborn insistence on repeating one’s own mistakes. Even the most obvious confounders such as selective memory or alternative causes for positive clinical outcomes are quickly dismissed or not even considered at all.
Avoiding cognitive dissonance at all cost
But believers still has to somehow deal with the scientific facts about homeopathy; and these are, of course, grossly out of line with their belief. Thus the external evidence and the internal belief would inevitably clash creating a shrill cognitive dissonance. This must be avoided at all cost, as it might threaten the believer’s peace of mind. And the solution is amazingly simple: scientific evidence that does not confirm the believer’s conviction is ignored or, when this proves to be impossible, turned upside down.
Rachel Roberts’ account is most enlightening also in this repect:
And yet I keep reading reports in the media saying that homeopathy doesn’t work and that this scientific evidence doesn’t exist.
The facts, it seems, are being ignored. By the end of 2009, 142 randomised control trials (the gold standard in medical research) comparing homeopathy with placebo or conventional treatment had been published in peer-reviewed journals – 74 were able to draw firm conclusions: 63 were positive for homeopathy and 11 were negative. Five major systematic reviews have also been carried out to analyse the balance of evidence from RCTs of homeopathy – four were positive (Kleijnen, J, et al; Linde, K, et al; Linde, K, et al; Cucherat, M, et al) and one was negative (Shang, A et al). It’s usual to get mixed results when you look at a wide range of research results on one subject, and if these results were from trials measuring the efficacy of “normal” conventional drugs, ratios of 63:11 and 4:1 in favour of a treatment working would be considered pretty persuasive.
This statement is, in my view, a classic example of a desperate misinterpretation of the truth as a means of preventing the believer’s house of cards from collapsing. It even makes the hilarious claim that not the believers but the doubters “ignore” the facts.
In order to be able to adhere to her belief, Roberts needs to rely on a woefully biased white-wash from the ‘British Homeopathic Association’. And, in order to be on the safe side, she even quotes it misleadingly. The conclusion of the Cucherat review, for instance, can only be seen as positive by most blinkered of minds: There is some evidence that homeopathic treatments are more effective than placebo; however, the strength of this evidence is low because of the low methodological quality of the trials. Studies of high methodological quality were more likely to be negative than the lower quality studies. Further high quality studies are needed to confirm these results. Contrary to what Roberts states, there are at least a dozen more than 5 systematic reviews of homeopathy; my own systematic review of systematic reviews, for example, concluded that the best clinical evidence for homeopathy available to date does not warrant positive recommendations for its use in clinical practice.
It seems that, at this stage of a believer’s development, the truth gets all too happily sacrificed on the altar of faith. All these ‘ex-sceptics’ turned believers are now able to display is a rather comical parody of scepticism.
The delusional end-stage
The last stage in the career of a believer has been reached when hardly anything that he or she is convinced of resembles reality any longer. I don’t know much about Rachel Roberts, and she might not have reached this point yet; but there are many others who clearly have.
My two favourite examples of end-stage homeopathic delusionists are John Benneth and Dana Ullman. The final stage on the journey from ‘sceptic scientist’ to delusional disciple is characterised by an incessant stream of incoherent statements of vile nonsense that beggars belief. It is therefore easy to recognise and, because nobody can possibly take the delusionists seriously, they are best viewed as relatively harmless contributors to medical comedy.
Why does all of this matter?
Many homeopathy-fans are quasi-religious believers who, in my experience, have degressed way beyond reason. It is therefore a complete waste of time trying to reason with them. Initiated by a highly emotional epiphany, their faith cannot be shaken by rational arguments. Similar but usually less pronounced attitudes, I am afraid, can be observed in true believers of other alternative treatments as well (here I have chosen the example of homeopathy mainly because it is the area where things are most explicit).
True believers claim to have started out as sceptics and they often insist to be driven by a scientific mind. Yet I have never seen any evidence for these assumptions. On the contrary, for a relatively trivial episode to become a life-changing epiphany, the believer’s mind needs to be lamentably unscientific, unquestioning and simple.
In my experience, true believers will not change their mind; I have never seen this happening. However, progress might nevertheless be made, if we managed to instil a more (self-) questioning rationality and scientific attitudes into the minds of the next generations. In other words, we need better education in science and more training of critical thinking during their formative years.
What is ear acupressure?
Proponents claim that ear-acupressure is commonly used by Chinese medicine practitioners… It is like acupuncture but does not use needles. Instead, small round pellets are taped to points on one ear. Ear-acupressure is a non-invasive, painless, low cost therapy and no significant side effects have been reported.
Ok, but does it work?
There is a lot of money being made with the claim that ear acupressure (EAP) is effective, especially for smoking cessation; entrepreneurs sell gadgets for applying the pressure on the ear, and practitioners earn their living through telling their patients that this therapy is helpful. There are hundreds of websites with claims like this one: Auricular therapy (Acupressure therapy of the ear region) has been used successfully for Smoking cessation. Auriculotherapy is thought to be 7 times more powerful than other methods used for smoking cessation; a single auriculotherapy treatment has been shown to reduce smoking from 20 or more cigarettes a day down to 3 to 5 a day.
But what does the evidence show?
This new study investigated the efficacy of EAP as a stand-alone intervention for smoking cessation. Adult smokers were randomised to receive EAP specific for smoking cessation (SSEAP) or a non-specific EAP (NSEAP) intervention, EAP at points not typically used for smoking cessation. Participants received 8 weekly treatments and were requested to press the five pellets taped to one ear at least three times per day. Participants were followed up for three months. The primary outcome measures were a 7-day point-prevalence cessation rate confirmed by exhaled carbon monoxide and relief of nicotine withdrawal symptoms (NWS).
Forty-three adult smokers were randomly assigned to SSEAP (n = 20) or NSEAP (n = 23) groups. The dropout rate was high with 19 participants completing the treatments and 12 remaining at followup. One participant from the SSEAP group had confirmed cessation at week 8 and end of followup (5%), but there was no difference between groups for confirmed cessation or NWS. Adverse events were few and minor.
And is there a systematic review of the totality of the evidence?
Sure, the current Cochrane review arrives at the following conclusion: There is no consistent, bias-free evidence that acupuncture, acupressure, laser therapy or electrostimulation are effective for smoking cessation…
Yes, we may well ask! If most TCM practitioners use EAP or acupuncture for smoking cessation telling their customers that it works (and earning good money when doing so), while the evidence fails to show that this is true, what should we say about such behaviour? I don’t know about you, but I find it thoroughly dishonest.
