Have you ever wondered whether doctors who practice homeopathy are different from those who don’t.
Silly question, of course they are! But how do they differ?
Having practised homeopathy myself during my very early days as a physician, I have often thought about this issue. My personal (and not very flattering) impressions were noted in my memoir where I describe my experience working in a German homeopathic hospital:
… some of my colleagues used homeopathy and other alternative approaches because they could not quite cope with the often exceedingly high demands of conventional medicine. It is almost understandable that, if a physician was having trouble comprehending the multifactorial causes and mechanisms of disease and illness, or for one reason or another could not master the equally complex process of reaching a diagnosis or finding an effective therapy, it might be tempting instead to employ notions such as dowsing, homeopathy or acupuncture, whose theoretical basis, unsullied by the inconvenient absolutes of science, was immeasurably more easy to grasp.
Some of my colleagues in the homeopathic hospital were clearly not cut out to be “real” doctors. Even a very junior doctor like me could not help noticing this somewhat embarrassing fact…
But this is anecdote and not evidence!
So, where is the evidence?
It was published last week and made headlines in many UK daily papers.
Our study was aimed at finding out whether English GP practices that prescribe any homeopathic preparations might differ in their prescribing of other drugs. We identified practices that made any homeopathy prescriptions over six months of data. We measured associations with four prescribing and two practice quality indicators using multivariable logistic regression.
Only 8.5% of practices (644) prescribed homeopathy between December 2016 and May 2017. Practices in the worst-scoring quartile for a composite measure of prescribing quality were 2.1 times more likely to prescribe homeopathy than those in the best category. Aggregate savings from the subset of these measures where a cost saving could be calculated were also strongly associated. Of practices spending the most on medicines identified as ‘low value’ by NHS England, 12.8% prescribed homeopathy, compared to 3.9% for lowest spenders. Of practices in the worst category for aggregated price-per-unit cost savings, 12.7% prescribed homeopathy, compared to 3.5% in the best category. Practice quality outcomes framework scores and patient recommendation rates were not associated with prescribing homeopathy.
We concluded that even infrequent homeopathy prescribing is strongly associated with poor performance on a range of prescribing quality measures, but not with overall patient recommendation or quality outcomes framework score. The association is unlikely to be a direct causal relationship, but may reflect underlying practice features, such as the extent of respect for evidence-based practice, or poorer stewardship of the prescribing budget.
Since our study was reported in almost all of the UK newspapers, it comes as no surprise that, in the interest of ‘journalistic balance’, homeopaths were invited to give their ‘expert’ opinions on our work.
Margaret Wyllie, head of the British Homeopathic Association, was quoted commenting: “This is another example of how real patient experience and health outcomes are so often discounted, when in actuality they should be the primary driver for research to improve our NHS services. This study provides no useful evidence about homeopathy, or about prescribing, and gives absolutely no data that can improve the health of people in the UK.”
The Faculty of Homeopathy was equally unhappy about our study and stated: “The study did not include any measures of patient outcomes, so it doesn’t tell us how the use of homeopathy in English general practice correlates with patients doing well or badly, nor with how many drugs they use.”
Cristal Summer from the Society of Homeopathy said that our research was just a rubbish bit of a study.
Peter Fisher, the Queen’s homeopath and the president of the Faculty of Homeopathy, stated: “We don’t know if these measures correlate with what matters to patients – whether they get better and have side-effects.”
A study aimed at determining whether GP practices that prescribe homeopathic preparations differ in their prescribing habits from those that do not prescribe homeopathics can hardly address these questions, Peter. A test of washing machines can hardly tell us much about the punctuality of trains. And an investigation into the risks of bungee jumping will not inform us about the benefits of regular exercise. Call me biased, but to me these comments indicate mainly one thing: HOMEOPATHS SEEM TO HAVE GREAT DIFFICULTIES UNDERSTANDING SCIENTIFIC PAPERS.
I much prefer the witty remarks of Catherine Bennett in yesterday’s Observer: Homeopath-GPs, naturally, have mustered in response and challenge Goldacre’s findings, with a concern for methodology that could easily give the impression that there is some evidential basis for their parallel system, beyond the fact that the Prince of Wales likes it. In fairness to Charles, his upbringing is to blame. But what is the doctors’ excuse?
Osteopathy is an odd alternative therapy. In many parts of the world it is popular; the profession differs dramatically from country to country; and there is not a single condition for which we could say that osteopathy out-performs other options. No wonder then that osteopaths would be more than happy to find a new area where they could practice their skills.
Perhaps surgical care is such an area?
The aim of this systematic review was to present an overview of published research articles within the subject field of osteopathic manipulative treatment (OMT) in surgical care. The authors evaluated peer-reviewed research articles published in osteopathic journals during the period 1990 to 2017. In total, 10 articles were identified.
Previous research has been conducted within the areas of abdominal, thoracic, gynecological, and/or orthopedic surgery. The studies included outcomes such as pain, analgesia consumption, length of hospital stay, and range of motion. Heterogeneity was identified in usage of osteopathic techniques, treatment duration, and occurrence, as well as in the osteopath’s experience.
The authors concluded that despite the small number of research articles within this field, both positive effects as well as the absence of such effects were identified. Overall, there was a heterogeneity concerning surgical contexts, diagnoses, signs and symptoms, as well as surgical phases in current interprofessional osteopathic publications. In this era of multimodal surgical care, the authors concluded, there is an urgent need to evaluate OMT in this context of care and with a proper research approach.
This is an odd conclusion, if there ever was one!
The facts are fairly straight forward:
- Osteopaths would like to expand into the area of surgical care [mainly, I suspect, because it would be good for business]
- There is no plausible reason why OMT should be beneficial in this setting.
- Osteopaths are not well-trained for looking after surgical patients.
- Physiotherapists, however, are and therefore there is no need for osteopaths on surgical wards.
- The evidence is extremely scarce.
- The available trials are of poor quality.
- Their results are contradictory.
- Therefore there is no reliable evidence to show that OMT is effective.
The correct conclusion of this review should thus be as follows:
THE AVAILABLE EVIDENCE FAILS TO SHOW EFFECTIVENESS OF OMT. THEREFORE THIS APPROACH CANNOT BE RECOMMENDED.
End of story.
I have often criticised papers published by chiropractors.
This article is excellent and I therefore quote extensively from it.
The objective of this systematic review was to investigate, if there is any evidence that spinal manipulations/chiropractic care can be used in primary prevention (PP) and/or early secondary prevention in diseases other than musculoskeletal conditions. The authors conducted extensive literature searches to locate all studies in this area. Of the 13.099 titles scrutinized, 13 articles were included (8 clinical studies and 5 population studies). They dealt with various disorders of public health importance such as diastolic blood pressure, blood test immunological markers, and mortality. Only two clinical studies could be used for data synthesis. None showed any effect of spinal manipulation/chiropractic treatment.
The authors concluded that they found no evidence in the literature of an effect of chiropractic treatment in the scope of PP or early secondary prevention for disease in general. Chiropractors have to assume their role as evidence-based clinicians and the leaders of the profession must accept that it is harmful to the profession to imply a public health importance in relation to the prevention of such diseases through manipulative therapy/chiropractic treatment.
In addition to this courageous conclusion (the paper is authored by a chiropractor and published in a chiro journal), the authors make the following comments:
Beliefs that a spinal subluxation can cause a multitude of diseases and that its removal can prevent them is clearly at odds with present-day concepts, as the aetiology of most diseases today is considered to be multi-causal, rarely mono-causal. It therefore seems naïve when chiropractors attempt to control the combined effects of environmental, social, biological including genetic as well as noxious lifestyle factors through the simple treatment of the spine. In addition, there is presently no obvious emphasis on the spine and the peripheral nervous system as the governing organ in relation to most pathologies of the human body.
The ‘subluxation model’ can be summarized through several concepts, each with its obvious weakness. According to the first three, (i) disturbances in the spine (frequently called ‘subluxations’) exist and (ii) these can cause a multitude of diseases. (iii) These subluxations can be detected in a chiropractic examination, even before symptoms arise. However, to date, the subluxation has been elusive, as there is no proof for its existence. Statements that there is a causal link between subluxations and various diseases should therefore not be made. The fourth and fifth concepts deal with the treatment, namely (iv) that chiropractic adjustments can remove subluxations, (v) resulting in improved health status. However, even if there were an improvement of a condition following treatment, this does not mean that the underlying theory is correct. In other words, any improvement may or may not be caused by the treatment, and even if so, it does not automatically validate the underlying theory that subluxations cause disease…
Although at first look there appears to be a literature on this subject, it is apparent that most authors lack knowledge in research methodology. The two methodologically acceptable studies in our review were found in PubMed, whereas most of the others were identified in the non-indexed literature. We therefore conclude that it may not be worthwhile in the future to search extensively the non-indexed chiropractic literature for high quality research articles.
One misunderstanding requires some explanations; case reports are usually not considered suitable evidence for effect of treatment, even if the cases relate to patients who ‘recovered’ with treatment. The reasons for this are multiple, such as:
- Individual cases, usually picked out on the basis of their uniqueness, do not reflect general patterns.
- Individual successful cases, even if correctly interpreted must be validated in a ‘proper’ research design, which usually means that presumed effect must be tested in a properly powered and designed randomized controlled trial.
- One or two successful cases may reflect a true but very unusual recovery, and such cases are more likely to be written up and published as clinicians do not take the time to marvel over and spend time on writing and publishing all the other unsuccessful treatment attempts.
- Recovery may be co-incidental, caused by some other aspect in the patient’s life or it may simply reflect the natural course of the disease, such as natural remission or the regression towards the mean, which in human physiology means that low values tend to increase and high values decrease over time.
- Cases are usually captured at the end because the results indicate success, meaning that the clinical file has to be reconstructed, because tests were used for clinical reasons and not for research reasons (i.e. recorded by the treating clinician during an ordinary clinical session) and therefore usually not objective and reproducible.
- The presumed results of the treatment of the disease is communicated from the patient to the treating clinician and not to a third, neutral person and obviously this link is not blinded, so the clinician is both biased in favour of his own treatment and aware of which treatment was given, and so is the patient, which may result in overly positive reporting. The patient wants to please the sympathetic clinician and the clinician is proud of his own work and overestimates the results.
- The long-term effects are usually not known.
- Further, and most importantly, there is no control group, so it is impossible to compare the results to an untreated or otherwise treated person or group of persons.
Nevertheless, it is common to see case reports in some research journals and in communities with readers/practitioners without a firmly established research culture it is often considered a good thing to ‘start’ by publishing case reports.
Case reports are useful for other reasons, such as indicating the need for further clinical studies in a specific patient population, describing a clinical presentation or treatment approach, explaining particular procedures, discussing cases, and referring to the evidence behind a clinical process, but they should not be used to make people believe that there is an effect of treatment…
For groups of chiropractors, prevention of disease through chiropractic treatment makes perfect sense, yet the credible literature is void of evidence thereof. Still, the majority of chiropractors practising this way probably believe that there is plenty of evidence in the literature. Clearly, if the chiropractic profession wishes to maintain credibility, it is time seriously to face this issue. Presently, there seems to be no reason why political associations and educational institutions should recommend spinal care to prevent disease in general, unless relevant and acceptable research evidence can be produced to support such activities. In order to be allowed to continue this practice, proper and relevant research is therefore needed…
All chiropractors who want to update their knowledge or to have an evidence-based practice will search new information on the internet. If they are not trained to read the scientific literature, they might trust any article. In this situation, it is logical that the ‘believers’ will choose ‘attractive’ articles and trust the results, without checking the quality of the studies. It is therefore important to educate chiropractors to become relatively competent consumers of research, so they will not assume that every published article is a verity in itself…
END OF QUOTES
YES, YES YES!!!
I am so glad that some experts within the chiropractic community are now publishing statements like these.
This was long overdue.
How was it possible that so many chiropractors so far failed to become competent consumers of research?
Do they and their professional organisations not know that this is deeply unethical?
Actually, I fear they do and did so for a long time.
Why then did they not do anything about it ages ago?
I fear, the answer is as easy as it is disappointing:
If chiropractors systematically trained to become research-competent, the chiropractic profession would cease to exist; they would become a limited version of physiotherapists. There is simply not enough positive evidence to justify chiropractic. In other words, as chiropractic wants to survive, it has little choice other than remaining ignorant of the current best evidence.
I hear this argument so regularly that it might be worth analysing it (yet again) a bit closer.
It is used with the deepest of convictions by proponents of all sorts of quackery who point out that science does not know or explain everything – and certainly not their (very special) therapy. Science is just not sophisticated enough, they say; in fact, a few years ago, it could not even explain how Aspirin works. And just like Aspirin, their very special therapy – let’s call it energy healing (EH) for the sake of this post – does definitely and evidently work. There even is ample proof:
- Patients get better after using EH, and surely patients don’t lie.
- Patients pay for EH, and who would pay for something that does not work?
- EH has survived hundreds of years, and ineffective therapies don’t.
- EH practitioners have tons of experience and therefore know best.
- They are respected by very important people and organisations.
- EH is even reimbursed by some insurance companies.
You have all heard the argument, I’m sure.
How to respond?
The ‘proofs’ listed above are simply fallacies; as such they do not need more detailed discussions, I hope.
But how can we refute the notion that science is not yet sufficiently advanced to explain EH?
The simplest approach might be to explain that science has already tested EH and found it to be ineffective. There really is nothing more to say. And the often-quoted example of Aspirin does clearly not wash. True, a few decades ago, we did not know how it worked. But we always knew that it worked because we conducted clinical trials, and they generated positive results. These findings we the main reasons why scientists wanted to find out how it works, and eventually they did (and even got a Nobel Prize for it). Had the clinical trials not shown effectiveness, nobody would have been interested in alleged mechanisms of action.
With EH, things are different. Rigorous clinical trials of EH have been conducted, and the totality of this evidence fails to show that EH works. Therefore, chasing after a mechanism of action would be silly and wasteful. It’s true, science cannot explain EH, but this is not because it is not yet sophisticated enough; it is because there is nothing to explain. EH has been disproven, and waffling about ‘science is not yet able to explain it’ is either a deliberate lie or a serious delusion.
So far so good. But what if EH had not been submitted to clinical trials?
In such cases, the above line of argument would not work very well.
For instance, as far as I know, there is not a single rigorous clinical trial of crystal healing (CH). Does that mean that perhaps CH-proponents are correct when claiming that it does evidently work and science simply cannot yet understand how?
No, I don’t think so.
Like most of the untested alternative therapies, CH is not based on plausible assumptions. In fact, the implausibility of the underlying assumptions is the reason why such treatments have not and probably never will be submitted to rigorous clinical trials. Why should anyone waste his time and our money running expensive tests on something that is so extremely unlikely? Arguably doing so would even be unethical.
With highly implausible therapies we need no trials, and we do not need to fear that science is not yet sufficiently advance to explain them. In fact, science is sufficiently advanced to be certain that there can be no explanation that is in line with the known laws of nature.
Sadly, some truly deluded fans of CH might still not be satisfied and respond to our reasoning that we need a ‘paradigm shift’. They might say that science cannot explain CH because it is stuck in the straightjacket of an obsolete paradigm which does not cater for phenomena like CH.
Yet this last and desperate attempt of the fanatics is not a logical refuge. Paradigm shifts are not required because some quack thinks so, they are needed only if data have been emerging that cannot possibly be explained within the current paradigm. But this is never the case in alternative medicine. We can explain all the experience of advocates, positive results of researchers and ‘miracle’ cures of patients that are being reported. We know that the experiences are real, but are sure that their explanations of the experience are false. They are not due to the treatment per se but to other phenomena such as placebo effects, natural history, regression towards the mean, spontaneous recovery, etc.
So, whichever way we turn things, and whichever way enthusiasts of alternative therapies twist them, their argument that ‘SCIENCE IS NOT YET ABLE TO EXPLAIN’ is simply wrong.
Samuel Hahnemann published a lot, but his main ideas about homeopathy are summarised in his ‘Organon‘ which has thus become ‘the bible’ for all homeopaths. They regularly refer to this book, yet I sometimes get the impression that many of them have even read it.
I did! Most recently, I re-studied it when writing my own book ‘HOMEOPATHY, THE UNDILUTED FACTS‘. And I have to say, it is rather boring, full of contradictions and obsolete nonsense.
To mark Samuel’s birthday – he was born on 10 April 1755 in Meissen – I take the liberty of quoting directly from Dudgeon’s translation of the 1st edition of the Organon:
- In no way whatever can [a] disease itself be recognized.
- This eternal, universal law of nature [the like cures like assumption]…
- …only one disease can exist in the body at any one time…
- …if an acute infection attacks an organism already suffering from a similar acute disease, then the stronger infection uproots the weaker entirely and removes it homoeopathically.
- …diseases are only destroyed by similar diseases.
- …it is certain that a suitably selected homoeopathic remedy gently destroys and removes disease…
- …aggravation during the first hours… is, in fact, a very good prognostic sign…
- …even the smallest dose of a homoeopathic remedy always causes a small homoeopathic aggravation…
- …we should always choose the very smallest doses…
- …hardly any dose of the homoeopathically selected remedy can be so small as not to be stronger than the natural disease…
- If dilution is also employed… an excessive effect is easily produced.
- …a single drop of a tincture to a pound of water and shaking vigorously… will produce more effect than a single dose of eight drops of the tincture.
- …this action must be called spirit-like.
For homeopaths, these quotes (should) depict some of the central assumptions of homeopathy. For non-homeopaths, they are just gibberish that makes no sense whatsoever. Time has moved on, and most of us have moved with it. Yet homeopaths still live by (and from) the errors of 200 years ago.
Hahnemann died on 2 July 1843 in Paris. I don’t want to be disrespectful, but perhaps we should, in future, rather celebrate this date? It could be a celebration of the progress we made since (and because) we have recognised Hahnemann’s errors.
In the current issue of the Faculty of Homeopathy‘s Simile publication, Dr Peter Fisher, the Queen’s homeopath, re-visits the old story of the ‘Smallwood Report’. To my big surprise, I found the following two paragraphs in his editorial:
A prepublication draft [of the Smallwood report] was circulated for comment with prominent warnings that it was confidential and not to be shared more widely (I can personally vouch for this, since I was one of those asked to comment). Regrettably, Prof Ernst did precisely this, leaking it to The Times who used it as the basis of their lead story. The editor of The Lancet, Richard Horton, certainly no friend of homeopathy, promptly denounced Ernst for having “broken every professional code of scientific behaviour”.
Sir Michael Peat, the Prince of Wales’ Principal Private Secretary, wrote to the vice chancellor of Exeter University protesting at the leak, and the university conducted an investigation. Ernst’s position became untenable, funding for his department dried up and he took early retirement. Thirteen years later he remains sore; in his latest book More Harm than Good? he attacks the Prince of Wales as “foolish and immoral”.
END OF QUOTE
Sadly it is true that Horton wrote these defaming words. Subsequently, I asked him to justify them explaining that they were being used by my university against me. He ignored several of my emails, but eventually he sent a reply. In it, he said that, since the university was investigating the issue, the truth would doubtlessly be disclosed. I remember that I was livid at the arrogance and ignorance of this reply. However, being in the middle of my university’s investigation against me, never did anything about it. Looking back at this part of the episode, I feel that Horton behaved abominably.
But back to Dr Fisher.
Why did his defamatory and false accusation in his new editorial come as a ‘big surprise’ to me?
Should I not have gotten used to the often odd way in which some homeopaths handle the truth?
Yes, I did get used to this phenomenon; but I am nevertheless surprised because I have tried to correct Fisher’s ‘error’ before.
This is from a post about Fisher which I published in 2015:
In this article [available here in archive,org – Admin] which he published as Dr. Peter Fisher, Homeopath to Her Majesty, the Queen, he wrote: There is a serious threat to the future of the Royal London Homoeopathic Hospital (RLHH), and we need your help…Lurking behind all this is an orchestrated campaign, including the ’13 doctors letter’, the front page lead in The Times of 23 May 2006, Ernst’s leak of the Smallwood report (also front page lead in The Times, August 2005), and the deeply flawed, but much publicised Lancet meta-analysis of Shang et al…
If you have read my memoir, you will know that even the hostile 13-months investigation my own university did not find me guilty of the ‘leak’. The Times journalist who interviewed me about the Smallwood report already had the document on his desk when we spoke, and I did not disclose any contents of the report to him…
END OF QUOTE
So, assuming that Dr Peter Fisher has seen my 2015 post, he is knowingly perpetuating a slanderous untruth. However, giving him the benefit of the doubt, he might not have read the post nor my memoir and could be unaware of the truth. Error or lie? I am determined to find out and will send him today’s post with an offer to clarify the situation.
I will keep you posted.
In recent days, journalists across the world had a field day (mis)reporting that doctors practising integrative medicine were doing something positive after all. I think that the paper shows nothing of the kind – but please judge for yourself.
The authors of this article wanted to determine differences in antibiotic prescription rates between conventional General Practice (GP) surgeries and GP surgeries employing general practitioners (GPs) additionally trained in integrative medicine (IM) or complementary and alternative medicine (CAM) (referred to as IM GPs) working within National Health Service (NHS) England.
They conducted a retrospective study on antibiotic prescription rates per STAR-PU (Specific Therapeutic group Age–sex weighting Related Prescribing Unit) using NHS Digital data over 2016. Publicly available data were used on prevalence of relevant comorbidities, demographics of patient populations and deprivation scores. setting Primary Care. Participants were 7283 NHS GP surgeries in England. The association between IM GPs and antibiotic prescribing rates per STAR-PU with the number of antibiotic prescriptions (total, and for respiratory tract infection (RTI) and urinary tract infection (UTI) separately) as outcome. results IM GP surgeries (n=9) were comparable to conventional GP surgeries in terms of list sizes, demographics, deprivation scores and comorbidity prevalence.
Statistically significant fewer total antibiotics were prescribed at NHS IM GP surgeries compared with conventional NHS GP surgeries. In contrast, the number of antibiotics prescribed for UTI were similar between both practices.
The authors concluded that NHS England GP surgeries employing GPs additionally trained in IM/CAM have lower antibiotic prescribing rates. Accessibility of IM/CAM within NHS England primary care is limited. Main study limitation is the lack of consultation data. Future research should include the differences in consultation behaviour of patients self-selecting to consult an IM GP or conventional surgery, and its effect on antibiotic prescription. Additional treatment strategies for common primary care infections used by IM GPs should be explored to see if they could be used to assist in the fight against antimicrobial resistance.
The study was flimsy to say the least:
- It was retrospective and is therefore open to no end of confounders.
- There were only 9 surgeries in the IM group.
Moreover, the results were far from impressive. The differences in antibiotic prescribing between the two groups of GP surgeries were minimal or non-existent. Finally, the study was financed via an unrestricted grant of WALA Heilmittel GmbH, Germany (“approx. 900 different remedies conforming to the anthroposophic understanding of man and nature”) and its senior author has a long track record of publishing papers promotional for anthroposophic medicine.
Such pseudo-research seems to be popular in the realm of CAM, and I have commented before on similarly futile projects. The comparison, I sometimes use is that of a Hamburger restaurant:
Employees by a large Hamburger chain set out to study the association between utilization of Hamburger restaurant services and vegetarianism. The authors used a retrospective cohort design. The study population comprised New Hampshire residents aged 18-99 years, who had entered the premises of a Hamburger restaurant within 90 days for a primary purpose of eating. The authors excluded subjects with a diagnosis of cancer. They measured the likelihood of vegetarianism among recipients of services delivered by Hamburger restaurants compared with a control group of individuals not using meat-dispensing facilities. They also compared the cohorts with regard to the money spent in Hamburger restaurants. The adjusted likelihood of being a vegetarian was 55% lower among the experimental group compared to controls. The average money spent per person in Hamburger restaurants were also significantly lower among the Hamburger group.
To me, it is obvious that such analyses must produce a seemingly favourable result for CAM. In the present case, there are several reasons for this:
- GPs who volunteer to be trained in CAM tend to be in favour of ‘natural’ treatments and oppose synthetic drugs such as antibiotics.
- Education in CAM would only re-inforce this notion.
- Similarly, patients electing to consult IM GPs tend to be in favour of ‘natural’ treatments and oppose synthetic drugs such as antibiotics.
- Such patients might be less severely ill that the rest of the patient population (the data from the present study do in fact imply this to be true).
- These phenomena work in concert to generate less antibiotic prescribing in the IM group.
In the final analysis, all this finding amounts to is a self-fulfilling prophecy: grocery shops sell less meat than butchers! You don’t believe me? Perhaps you need to read a previous post then; it concluded that physicians practicing integrative medicine (the 80% who did not respond to the survey were most likely even worse) not only use and promote much quackery, they also tend to endanger public health by their bizarre, irrational and irresponsible attitudes towards vaccination.
What is upsetting with the present paper, in my view, are the facts that:
- a reputable journal published this junk,
- the international press has a field-day reporting this study implying that CAM is a good thing.
The fact is that it shows nothing of the kind. Imagine we send GPs on a course where they are taught to treat all their patients with blood-letting. This too would result in less prescription of antibiotics, wouldn’t it? But would it be a good thing? Of course not!
True, we prescribe too much antibiotics. Nobody doubts that. And nobody doubts that it is a big problem. The solution to this problem is not more CAM, but less antibiotics. To realise the solution we do not need to teach GPs CAM but we need to remind them of the principles of evidence-based practice. And the two are clearly not the same; in fact, they are opposites.
Did you know that chiropractic is a religion?
Well, not quite but almost.
DD Palmer seriously toyed with the idea of turning chiropractic into a religion.
And rightly so!
In the absence of evidence, belief is everything.
And this is why, to this day, so many chiropractors bank (a most appropriate term in this context!) on belief rather than evidence.
Look, for instance at this lovely advertisement I found on Twitter (there are many more, but this one has to stand for the many).
Seven common benefits of chiropractic care!?!
Beneath the picture of a pathologically straight spine – if that is what chiro does to you, avoid it at all cost! – we see the name of the ‘doctor’ who seems to have designed this impressive picture. ‘Dr’ Schluter is even more versatile than his pretty advertisement implies; he also seems to treat newborn babies! And on his website he also tells us that he is able to treat allergies:
You may be surprised to find that chiropractic can do a great deal to alleviate some allergies. Allergies are very common and we become so used to their effect on us that we tend to ignore their symptoms. And many people are unaware of the gradual decline in health that results. Chiropractic treatment didn’t necessarily set out specifically to provide care for allergies, but due to the nature of the chiropractic care and its effect on the nervous system, it has been shown to help.
If we look at some of the common signs of allergies we find that they include some unexpected examples. Not only do we find the usual ones – asthma, sinus congestion, sneezing, itchy eyes, skin rashes and running nose – but also weight gain, Acne and even fluid retention and heartburn.
Many people approach the problem of allergies as though all allergens affect everyone in the same way; this is not the case. Because we are individuals, different allergens affect each of us in differing ways. Some allergens affect some and not others. Consequently treating the condition must be approached on this basis of individuality.
It may not be the pet fur or dried saliva that is kicked up as your pooch washes and scratches; it may also not be the pollen, grass dust or other one of the many irritants in the air at any one time. It could be that due to a misalignment of the spine (or subluxation), mild though it may be, the nervous system is finding it difficult to help the body adapt to its surroundings and is therefore unable to deal with the necessary adjustments.
As an individual you need to treat your body’s physical and nervous system as such. You could be, without even being aware of it, in a generally stressed condition – this may be through lack of sleep, poor nutrition or any one of a combination of the many other stressors affecting us daily. Suddenly you find that with the first spring pollen dust that comes along you begin to wheeze and sneeze!
You may not have previously connected chiropractors and allergies but, for you or someone you know, the connection could help.
Schluter Chiropractic works on the principle of reducing interference so the nervous system and body can work better. Providing that any symptom or condition (including pain) is occurring as a result of nerve interference from vertebral subluxation, there is a very good chance that it will improve with chiropractic care.

Wise words indeed.
Like most chiros, ‘Dr’ Schulter seems to be a true miracle-worker; and because he can do miracles, he does not need to be rational or concerned about evidence or worried about telling the truth.
For Christ sake, it’s Easter!
We ought to show a bit of belief!!!
Because without it, the benefits of chiropractic would be just an illusion.
Chiropractors are fast giving up the vitalistic and obsolete concepts of their founding fathers, we are told over and over again. But are these affirmations true? There are good reasons to be sceptical. Take this recent paper, for instance.
The objective of this survey was to investigate the proportion of Australian chiropractic students who hold non-evidence-based beliefs in the first year of study and to determine the extent to which they may be involved in non-musculoskeletal health conditions.
Students from two Australian chiropractic programs were invited to answer a questionnaire on how often they would give advice on 5 common health conditions in their future practices, as well as to provide their opinion on whether chiropractic spinal adjustments could prevent or help seven health-related conditions.
The response rate of this survey was 53%. Students were highly likely to offer advice on a range of non-musculoskeletal conditions. The proportions were lowest in first year and highest the final year. For instance, 64% of students in year 4/5 believed that spinal adjustments improve the health of infants. Also, high numbers of students held non-evidence-based beliefs about ‘chiropractic spinal adjustments’ which tended to occur in gradually decreasing in numbers in sequential years, except for 5th and final year, when a reversal of the pattern occurred.
The authors concluded that new strategies are required for chiropractic educators if they are to produce graduates who understand and deliver evidence-based health care and able to be part of the mainstream health care system.
This is an interesting survey, but I think its conclusion is wrong!
- Educators do not require ‘new strategies’, I would argue; they simply need to take their duty of educating students seriously – educating in this context does not mean brain-washing, it means teaching facts and evidence-based practice. And this is were any concept of true education would run into problems: it would teach students that chiropractic is built on sand.
- Conclusions need to be based on the data presented. Therefore, the most fitting conclusion, in my view, is that chiropractic students are currently being educated such that, once let loose on the unsuspecting and often all too gullible public, they will be a menace and a serious danger to public health.
You might say that this survey is from Australia and that the findings therefore do not necessarily apply to other countries. Correct! However, I very much fear that elsewhere the situation is similar or perhaps even worse. And my fear does not come out of thin air, it is based on things we have discussed before; see for instance these three posts:
But I would be more than willing to change my mind – provided someone can show me good evidence to the contrary.
The media have (rightly) paid much attention to the three Lancet-articles on low back pain (LBP) which were published this week. LBP is such a common condition that its prevalence alone renders it an important subject for us all. One of the three papers covers the treatment and prevention of LBP. Specifically, it lists various therapies according to their effectiveness for both acute and persistent LBP. The authors of the article base their judgements mainly on published guidelines from Denmark, UK and the US; as these guidelines differ, they attempt a synthesis of the three.
Several alternative therapist organisations and individuals have consequently jumped on the LBP bandwagon and seem to feel encouraged by the attention given to the Lancet-papers to promote their treatments. Others have claimed that my often critical verdicts of alternative therapies for LBP are out of line with this evidence and asked ‘who should we believe the international team of experts writing in one of the best medical journals, or Edzard Ernst writing on his blog?’ They are trying to create a division where none exists,
The thing is that I am broadly in agreement with the evidence presented in Lancet-paper! But I also know that things are a bit more complex.
Below, I have copied the non-pharmacological, non-operative treatments listed in the Lancet-paper together with the authors’ verdicts regarding their effectiveness for both acute and persistent LBP. I find no glaring contradictions with what I regard as the best current evidence and with my posts on the subject. But I feel compelled to point out that the Lancet-paper merely lists the effectiveness of several therapeutic options, and that the value of a treatment is not only determined by its effectiveness. Crucial further elements are a therapy’s cost and its risks, the latter of which also determines the most important criterion: the risk/benefit balance. In my version of the Lancet table, I have therefore added these three variables for non-pharmacological and non-surgical options:
|EFFECTIVENESS ACUTE LBP||EFFECTIVENESS PERSISTENT LBP||RISKS||COSTS||RISK/BENEFIT BALANCE|
|Advice to stay active||+, routine||+, routine||None||Low||Positive|
|Education||+, routine||+, routine||None||Low||Positive|
|Superficial heat||+/-||Ie||Very minor||Low to medium||Positive (aLBP)|
|Exercise||Limited||+/-, routine||Very minor||Low||Positive (pLBP)|
|CBT||Limited||+/-, routine||None||Low to medium||Positive (pLBP)|
|Rehab||Ie||+/-||Minor||Medium to high||Questionable|
Routine = consider for routine use
+/- = second line or adjunctive treatment
Ie = insufficient evidence
Limited = limited use in selected patients
vfbmae = very frequent, minor adverse effects
sae = serious adverse effects, including deaths, are on record
aLBP = acute low back pain
The reason why my stance, as expressed on this blog and elsewhere, is often critical about certain alternative therapies is thus obvious and transparent. For none of them (except for massage) is the risk/benefit balance positive. And for spinal manipulation, it even turns out to be negative. It goes almost without saying that responsible advice must be to avoid treatments for which the benefits do not demonstrably outweigh the risks.
I imagine that chiropractors, osteopaths and acupuncturists will strongly disagree with my interpretation of the evidence (they might even feel that their cash-flow is endangered) – and I am looking forward to the discussions around their objections.
