I have said it often, and I say it again: I do like well-conducted systematic reviews; and Cochrane reviews are usually the best, i. e. most transparent, most thorough and least biased. Thus, I was pleased to see a new Cochrane review of acupuncture aimed at assessing the benefits and harms of acupuncture in patients with hip OA.

The authors included randomized controlled trials (RCTs) that compared acupuncture with sham acupuncture, another active treatment, or no specific treatment; and RCTs that evaluated acupuncture as an addition to another treatment. Major outcomes were pain and function at the short term (i.e. < 3 months after randomization) and adverse events.

Six RCTs with 413 participants were included. Four RCTs included only people with OA of the hip, and two included a mix of people with OA of the hip and knee. All RCTs included primarily older participants, with a mean age range from 61 to 67 years, and a mean duration of hip OA pain from two to eight years. Approximately two-thirds of participants were women. Two RCTs compared acupuncture versus sham acupuncture; the other four RCTs were not blinded. All results were evaluated at short-term (i.e. four to nine weeks after randomization).In the two RCTs that compared acupuncture to sham acupuncture, the sham acupuncture control interventions were judged believable, but each sham acupuncture intervention was also judged to have a risk of weak acupuncture-specific effects, due to placement of non-penetrating needles at the correct acupuncture points in one RCT, and the use of penetrating needles not inserted at the correct points in the other RCT. For these two sham-controlled RCTs, the risk of bias was low for all outcomes.

The combined analysis of two sham-controlled RCTs gave moderate quality evidence of little or no effect in reduction in pain for acupuncture relative to sham acupuncture. Due to the small sample sizes in the studies, the confidence interval includes both the possibility of moderate benefit and the possibility of no effect of acupuncture (120 participants; Standardized Mean Difference (SMD) -0.13, (95% Confidence Interval (CI) -0.49 to 0.22); 2.1 points greater improvement with acupuncture compared to sham acupuncture on 100 point scale (i.e., absolute percent change -2.1% (95% CI -7.9% to 3.6%)); relative percent change -4.1% (95% CI -15.6% to 7.0%)). Estimates of effect were similar for function (120 participants; SMD -0.15, (95% CI -0.51 to 0.21)). No pooled estimate, representative of the two sham-controlled RCTs, could be calculated or reported for the quality of life outcome.

The four other RCTs were unblinded comparative effectiveness RCTs, which compared (additional) acupuncture to four different active control treatments. There was low quality evidence that addition of acupuncture to the routine primary care that RCT participants were receiving from their physicians was associated with statistically significant and clinically relevant benefits, compared to the routine primary physician care alone, in pain (1 RCT; 137 participants; mean percent difference -22.9% (95% CI -29.2% to -16.6%); relative percent difference -46.5% (95% CI -59.3% to -33.7%)) and function (mean percent difference -19.0% (95% CI -24.41 to -13.59); relative percent difference -38.6% (95% CI -49.6% to -27.6%)). There was no statistically significant difference for mental quality of life and acupuncture showed a small, significant benefit for physical quality of life.

The effects of acupuncture compared with either advice plus exercise or NSAIDs are uncertain. The authors are also uncertain whether acupuncture plus patient education improves pain, function, and quality of life, when compared to patient education alone.

In general, the overall quality of the evidence for the four comparative effectiveness RCTs was low to very low, mainly due to the potential for biased reporting of patient-assessed outcomes due to lack of blinding and sparse data.

Information on safety was reported in 4 RCTs. Two RCTs reported minor side effects of acupuncture, which were primarily minor bruising, bleeding, or pain at needle insertion sites.

The authors concluded that acupuncture probably has little or no effect in reducing pain or improving function relative to sham acupuncture in people with hip osteoarthritis. Due to the small sample size in the studies, the confidence intervals include both the possibility of moderate benefits and the possibility of no effect of acupuncture. One unblinded trial found that acupuncture as an addition to routine primary physician care was associated with benefits on pain and function. However, these reported benefits are likely due at least partially to RCT participants’ greater expectations of benefit from acupuncture. Possible side effects associated with acupuncture treatment were minor.

This is an excellent review of data that (because of contradictions, methodological limitations, heterogeneity etc.) are not easy to evaluate fairly. The review shows that previous verdicts about acupuncture for osteoarthritis might have been too optimistic. Acupuncture has no or only very small specific therapeutic effects. As we have much better therapeutic options for this condition, it means that acupuncture can no longer be recommended as an effective therapy.

That surely must be big news in the little world of acupuncture!

I have been personally involved in several similar reviews:

In 1997, I concluded that the most rigorous studies suggest that acupuncture is not superior to sham-needling in reducing pain of osteoarthritis: both alleviate symptoms to roughly the same degree.

In 2006, the balance of evidence seemed to have shifted and more positive data had emerged; consequently our review concluded that sham-controlled RCTs suggest specific effects of acupuncture for pain control in patients with peripheral joint OA. Considering its favourable safety profile acupuncture seems an option worthy of consideration particularly for knee OA. Further studies are required particularly for manual or electro-acupuncture in hip OA.

Now, it seems that my initial conclusion of 1996 was more realistic. To me this is a fascinating highlight on the fact that in EBM, we change our minds based on the current best evidence. By contrast, in alternative medicine, as we have often lamented on this blog, minds do not easily change and all too often dogma seems to reign.

The new Cochrane review is important in several ways. Firstly, it affirms an appropriately high standard for such reviews. Secondly, it originates from a research team that has, in the past, been outspokenly pro-acupuncture; it is therefore unlikely that the largely negative findings were due to an anti-acupuncture bias. Thirdly – and most importantly – osteoarthritis has been THE condition for which even critical reviewers had to admit that there was at least some good, positive evidence.

It seems therefore, that yet again a beautiful theory has been slain by an ugly fact.

Switzerland seems to be something like the ‘promised land’ for homeopaths – at least this is what many homeopaths seem think. However, homeopaths’ thinking is rarely correct, and the situation of homeopathy in Switzerland is not quite what they believe it to be.

This article explains (my English explanations are below for all those you cannot do German):

________________________________________________________________________________

Die Schweiz bekommt die steigenden Gesundheitskosten einfach nicht in den Griff. In den 20 Jahren zwischen 1996 und 2016 haben sie sich um rund 255,2 Prozent erhöht…
Einer der Gründe für den Anstieg: Seit 2017 sind Komplementärmedizinische Methoden wie beispielsweise Homöopathie auch in der Grundversorgung inbegriffen. Das Volk hatte im Jahr 2009 einen entsprechenden Verfassungsartikel angenommen. Damals hoffte man noch, dass mit dem erleichterten Zugang zur Komplementärmedizin die Gesundheitskosten sinken würden.
Doch es kam anders. Die Komplementärmedizin verursachte letztes Jahr zusätzliche Kosten von 30 Millionen Franken, wie Sandra Kobelt, Sprecherin Krankenkassenverbandes Santésuisse, gegenüber BLICK bestätigt.

Die Komplementärmedizin sorgt entsprechend weiter für Diskussionen. Auch, weil zum Beispiel die Wirkung der beliebten Globuli-Kügeli bis heute höchst umstritten bleibt. Doch auch sie werden laut neuem Gesetz in jedem Fall von der Krankenkasse bezahlt, sofern sie von einem Homöopathen mit medizinischem Fachausweis verschrieben wurden…

Aus wissenschaftlicher Sicht macht diese Bevorzugung der Homöopathie wenig Sinn. Denn: In einem Statement aus dem Jahr 2017 bestritten insgesamt 25 europäische Wissenschaftsvereinigungen die Wirksamkeit von Globuli. Darunter auch die Akademien der Wissenschaft Schweiz, die mit den Schweizer Hochschulen zusammenarbeiten. Sie halten fest, dass Homöopathie sogar gefährlich sein kann, da zu ihren Gunsten eine schulmedizinische Therapie aufgeschoben oder gar abgelehnt wird.

Dieser Meinung ist auch Beda Stadler, der ehemalige Leiter des Instituts für Immunologie an der Uni Bern. «Globuli verursachen nur unnötige Gesundheitskosten», sagt er. Man habe das Volk 2009 getäuscht, indem man ihm erzählte, Globuli wären ja günstig. «Doch viele Allergiker setzen die Globuli nicht ab, nachdem sie keine Wirkung festgestellt haben. Stattdessen schlucken sie noch zusätzlich medizinische Tabletten – das verursacht doppelte Kosten», so Stadler.

Homöopathin und Ärztin Doktor Gisela Etter hält dagegen. «Ich erlebe jeden Tag, wie Homöopathie bei Allergikern wirkt. Bei vielen treten die Symptome nach einiger Zeit überhaupt nicht mehr auf», sagt sie. Das Problem: Den Wirkungsmechanismus der Globuli kann die Medizinerin nicht erklären. «Das ist mit den herkömmlichen Naturwissenschaften gar nicht möglich», so Etter…

_________________________________________________________________________

Let me try to translate the key points of this article:

  • The costs for healthcare have exploded in Switzerland; an increase of > 255% during the last 10 years.
  • One reason for this development is that, since 2017, the Swiss get various alternative therapies reimbursed, including homeopathy.
  • That move has cost 30 000 000 Francs last year.
  • The efficacy of homeopathic remedies is controversial.
  • Yet they are being paid for by Swiss health insurances, provided they are prescribed by a qualified doctor.
  • This does not make sense from a scientific perspective.
  • In 2017, 25 European scientific societies, including the Swiss academies, stated that homeopathy does not work and can even be dangerous, if it replaces effective treatments.
  • Beda Stadler, former director of the Institute of Immunology, Uni Bern said “Globuli only cause unnecessary healthcare costs”
  • Homoeopath Gisela Etter said “I see every day how homeopathy works for allergies… to explain the mechanism of action is not possible with conventional science.”

__________________________________________________________________________________

I suppose, we will have to wait for some unconventional science then!

Many charities in the UK (and most other countries) openly promote bogus treatments. After having been reminded of this fact regularly, the UK Charity Commission have decided to look into this issue. Arguably, such charities – I have previously discussed ‘YES TO LIFE’  as an example (in total there are several hundred ‘SCAM charities’ operating in the UK today)-  do not provide a valuable public service and should therefore not benefit from such status and tax privileges. While the commission is contemplating, an article in the NEW SCIENTIST provided more information on this important issue. Here are a few excerpts:

A commission briefing document says the most important issue is the level of evidence it will require to judge whether a provider of complementary therapy dispenses services of benefit to public health, thereby qualifying legally for charitable status. The document says that at present, suitable evidence includes peer-reviewed research in recognised medical journals such as The Lancet or the BMJ, or recognition by the Department of Health or other government regulatory bodies. Personal testimonies and anecdotal evidence are not sufficient to demonstrate efficacy, says the commission, and nor are non-scientific articles and features promoting methods, treatments or therapies.

However, organisations such as the Good Thinking Society have presented evidence that these standards are not being applied rigorously, meaning some organisations may have been granted charitable status without the necessary evidence that their therapies are of benefit to public health. The commission is reassessing how its existing guidelines are enforced. It is also seeking guidance on how to deal with conflicting or inconsistent evidence, or evidence that certain therapies might cause harm – by displacing conventional therapies, for example.

Complementary providers argue that it’s unfair to be judged purely on evidence in mainstream medical journals, as demanded by the Good Thinking Society. “We know there’s a well-being factor with some complementary medicines which could be palliative, or a placebo effect,” says Jayney Goddard, director of The Complementary Medical Association. “These include massage or meditation, for example, which have tremendously supportive effects, but if the evidence isn’t forthcoming, it means those charities currently offering them might not be able to in future.” If the consultation does ultimately result in revocation of charitable status for some providers, Goddard argues that this would make it harder for them to raise donations and benefit from tax breaks that make their services more affordable.

END OF QUOTE

The argument of Jayney Goddard borders on the ridiculous, of course. If treatment X improves well-being beyond placebo and generates more good than harm, it is clearly effective and the above debate does not even apply. But it obviously does not suffice to claim that treatment X improves well-being, it is mandatory to demonstrate it with sound evidence. If, on the other hand, treatment X has not been shown to be effective beyond placebo, it must be categorised as unproven or bogus. And promoting bogus treatments/ideas/concepts (including diverting patients from evidence-based treatments and undermining rational thought in our society at large) is unquestionably harmful both to individual patients and to society as a whole.

SCAM charities are thus dangerous, unethical and an obstacle to progress. They not only should lose their charitable privileges as a matter of urgency, but they should also be fined for endangering public health.

 

 

You may remember my post entitled “How turn a negative trial into a positive one? Simple, just cheat!

No?

Let me remind you by copying the relevant parts of my original post of 20/2/2018:

…The purpose of their study was to examine the feasibility of Sipjeondaebo-tang (Juzen-taiho-to, Shi-Quan-Da-Bu-Tang) for cancer-related anorexia. A total of 32 participants with cancer anorexia were randomized to either Sipjeondaebo-tang group or placebo group. Participants were given 3 g of Sipjeondaebo-tang or placebo 3 times a day for 4 weeks. The primary outcome was a change in the Anorexia/Cachexia Subscale of Functional Assessment of Anorexia/Cachexia Therapy (FAACT). The secondary outcomes included Visual Analogue Scale (VAS) of anorexia, FAACT scale, and laboratory tests.

The results showed that anorexia and quality of life measured by FAACT and VAS were improved after 4 weeks of Sipjeondaebo-tang treatment. However, there was no significant difference between changes of Sipjeondaebo-tang group and placebo group.

From this, the authors of the study concluded that sipjeondaebo-tang appears to have potential benefit for anorexia management in patients with cancer. Further large-scale studies are needed to ensure the efficacy.

Well, isn’t this just great? Faced with a squarely negative result, one simply ignores it and draws a positive conclusion!

As we all know – and as trialists certainly must know – controlled trials are designed to compare the outcomes of two groups. Changes within one of the groups can be caused by several factors unrelated to the therapy and are therefore largely irrelevant. This means that “no significant difference between changes of Sipjeondaebo-tang group and placebo group” indicates that the herbal mixture had no effect. In turn this means that a conclusion stating that “sipjeondaebo-tang appears to have potential benefit for anorexia” is just fraudulent.

This level of scientific misconduct is remarkable, even for the notoriously poor ..

This article prompted me to do something I have only done once before: I filed an official complaint with the journal. I received a reply that they would look into it. Then there was silence; then came 2 or 3 emails that they are still considering my complaint. Yesterday, I finally received the following response:

Dear Dr. Ernst,

With reference to our correspondence below, thank you again for raising this matter, we appreciate your careful attention to the reporting of this article.  The authors have apologized for the error and said they did not check the abstract carefully enough when revising the article. The board decided that this may be addressed by publishing a corrigendum; please find the notice attached to this email.  Please let us know if you would like to be acknowledged in the notice for raising this issue, e.g. as follows: “This error in the reporting was brought to the attention of the journal by Prof. Edzard Ernst, Emeritus Professor of Complementary Medicine, University of Exeter.”

I look forward to hearing from you.

Kind regards…

And the attachment reads as follows:

In the article titled “Efficacy and Safety of Sipjeondaebo-Tang for Anorexia in Patients with Cancer: A Pilot, Randomized, Double-Blind, Placebo-Controlled Trial” [1], there was an error in the conclusion of the Abstract where the text reading “Sipjeondaebo-tang appears to have potential benefit for anorexia management in patients with cancer. Further large-scale studies are needed to ensure the efficacy” should be corrected to “In the present study, Sipjeondaebo-tang did not show a significant effect on anorexia in patients with cancer. Further large-scale studies which compensate for the limitations of this study are needed to assess the efficacy”.

So, what should we make of all this?

On the one hand, it is laudable that the Journal does correct the mistake. Bravo!!!

On the other hand, I find it odd that only the authors seem to be found guilty of an ‘error’. Even if it was just a error – and I am happy to give them the benefit of the doubt – there are other parties involved. The reviewers have a responsibility and so does the editor! Should they not own up to it?

In the end, this sorry tale does not restore my confidence in this Journal, quite the opposite. In view of all this, I have to repeat what I stated in my previous post:

I strongly suggest that:

  1. The journal is de-listed from Medline because similarly misleading nonsense has been coming out of this rag for some time.
  2. The paper is withdrawn because it can only mislead vulnerable patients.

PS

Needless to say that my reply to the above-cited email was to uphold my complaint and urge the Journal to publish an adequate response that includes and explains the failures of the reviewers and the editor. So: watch this space!

The RCC is a relatively new organisation. It is a registered charity claiming to promote “professional excellence, quality and safety in chiropractic… The organisation promotes and supports high standards of education, practice and research, enabling chiropractors to provide, and to be recognised for providing, high quality care for patients.”

I have to admit that I was not impressed by the creation of the RCC and lately have not followed what they are up to – not a lot, I assumed. But now they seem to plan a flurry of most laudable activities:

The Royal College of Chiropractors is developing a range of initiatives designed to help chiropractors actively engage with health promotion, with a particular focus on key areas of public health including physical activity, obesity and mental wellbeing.

Dr Mark Gurden, Chair of the RCC Health Policy Unit, commented:

“Chiropractors are well placed to participate in public health initiatives. Collectively, they have several million opportunities every year in the UK to support people in making positive changes to their general health and wellbeing, as well as helping them manage their musculoskeletal health of course.

Our recent AGM & Winter Conference highlighted the RCC’s intentions to encourage chiropractors to engage with a public health agenda and we are now embarking on a programme to:

  • Help chiropractors recognise the importance of their public health role;
  • Help chiropractors enhance their knowledge and skills in providing advice and support to patients in key areas of public health through provision of information, guidance and training;
  • Help chiropractors measure and recognise the impact they can have in key areas of public health.

To take this work forward, we will be exploring the possibility of launching an RCC Public Health Promotion & Wellbeing Society with a view to establishing a new Specialist Faculty in due course.”

END OF QUOTE

A ‘Public Health Promotion & Wellbeing Society’. Great!

As this must be new ground for the RCC, let me list a few suggestions as to how they could make more meaningful contributions to public health:

  • They could tell their members that immunisations are interventions that save millions of lives and are therefore in the interest of public health. Many chiropractors still have a very disturbed attitude towards immunisation: anti-vaccination attitudes still abound within the chiropractic profession. Despite a growing body of evidence about the safety and efficacy of vaccination, many chiropractors do not believe in vaccination, will not recommend it to their patients, and place emphasis on risk rather than benefit. In case you wonder where this odd behaviour comes from, you best look into the history of chiropractic. D. D. Palmer, the magnetic healer who ‘invented’ chiropractic about 120 years ago, left no doubt about his profound disgust for immunisation: “It is the very height of absurdity to strive to ‘protect’ any person from smallpox and other malady by inoculating them with a filthy animal poison… No one will ever pollute the blood of any member of my family unless he cares to walk over my dead body… ” (D. D. Palmer, 1910)
  • They could tell their members that chiropractic for children is little else than a dangerous nonsense for the sake of making money. Not only is there ‘not a jot of evidence‘ that it is effective for paediatric conditions, it can also cause serious harm. I fear that this suggestion is unlikely to be well-received by the RCC; they even have something called a ‘Paediatrics Faculty’!
  • They could tell their members that making bogus claims is not just naughty but hinders public health. Whenever I look on the Internet, I find more false than true claims made by chiropractors, RCC members or not.
  • They could tell their members that informed consent is not an option but an ethical imperative. Actually, the RCC do say something about the issue: The BMJ has highlighted a recent UK Supreme Court ruling that effectively means a doctor can no longer decide what a patient needs to know about the risks of treatment when seeking consent. Doctors will now have to take reasonable care to ensure the patient is aware of any material risks involved in any recommended treatment, and of any reasonable alternative or variant treatments. Furthermore, what counts as material risk can no longer be based on a responsible body of medical opinion, but rather on the view of ‘a reasonable person in the patient’s position’. The BMJ article is available here. The RCC feels it is important for chiropractors to be aware of this development which is relevant to all healthcare professionals. That’s splendid! So, chiropractors are finally being instructed to obtain informed consent from all their patients before starting treatment. This means that patients must be told that spinal manipulation is associated with very serious risks, AND that, in addition, ~ 50% of all patients will suffer from mild to moderate side effects, AND that there are always less risky and more effective treatments available for any condition from other healthcare providers.
  • The RCC could, for the benefit of public health, establish a compulsory register of adverse effects after spinal manipulations and make the data from it available to the public. At present such a register does not exist, and therefore its introduction would be a significant step in the right direction.
  • The RCC could make it mandatory for all members to adhere to the above points and establish a mechanism of monitoring their behaviour to make sure that, for the sake of public health, they all do take these issues seriously.

I do realise that the RCC may not currently have the expertise and know-how to adopt my suggestions, as these issues are rather new to them. To support the RCC in their praiseworthy endeavours, I herewith offer to give one or more evidence-based lectures on these subjects (at a date and place of their choice) in an attempt to familiarise the RCC and its members with these important aspects of public health. I also realise that the RCC may not have the funds to pay professorial lecture fees. Therefore, in the interest of both progress and public health, I offer to give these lectures for free.

I can be contacted via this blog.

I have often criticised papers published by chiropractors.

Not today!

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.

I have written about the use of homeopathy in France before (as I now live half of my time in France, this is a subject of considerable interest to me). After decades of deafening silence and uncritical acceptance by the French public, it seems that finally some change to the better might be on its way. Recently, a sizable number of prominent doctors protested publicly against the fact that, despite its implausibility and the lack of proof of efficacy, homeopathy continues to be reimbursed in France and scarce funds are being wasted on it. This action seems to have put pressure on officials to respond.

Yesterday (just in time for the ‘HOMEOPATHIC AWARENESS WEEK’) the French minister of health was quoted making a statement on homeopathy. Here is my translation of what Agnès Buzyn was quoted saying:

“There is a continuous evaluation of the medicines we call complementary. A working group* at the head office of my department checks that all these practices are not dangerous. If a therapy continues to be beneficial without being harmful, it continues to be reimbursed… The French are very attached [to homeopathy]; it’s probably a placebo effect. If it can prevent the use of toxic medicine, I think that we all win. I does not hurt.”

Agnès Buzyn

  • I would like to know who they are, how they can be contacted, and whether they would consider recruiting my assistance in evaluating alternative therapies.

So, if I understand her correctly, Agnès Buzyn believes that:

  1. the French people are fond of homeopathy;
  2. homeopathy is a placebo-therapy;
  3. homeopathy does no harm;
  4. homeopathy can even prevent harm from conventional medicine;
  5. on balance, therefore, homeopathy should continue to be reimbursed in France.

My views of this type of reasoning have been expressed repeatedly. Nevertheless, I will briefly state them again:

  1. true but not relevant; healthcare is not a popularity contest; and the current popularity is essentially the result of decades of systematic misinformation of consumers;
  2. correct;
  3. wrong: we have, on this blog, discussed ad nauseam how homeopathy can cause serious harm; for instance, whenever it replaces effective treatments, it can cause serious harm and might even kill patients;
  4. if doctors harm patients by needlessly prescribing harmful treatments, we need to re-train them and stop this abuse; using homeopathy is not the solution to bad medicine;
  5. wrong: the reimbursement of homeopathy is a waste of money and undermines evidence-based medicine.

So, what’s the conclusion?

Politicians are usually not good at understanding science or scientific evidence. They (have to?) think in time spans from one election to the next. And they are, of course, keenly aware that, in order to stay in power, they rely on the vote of the people. Therefore, the popularity of homeopathy (even though it is scientifically irrelevant) is a very real factor for them. This means that, on a political level, homeopathy is sadly much more secure than it should be. In turn, this means we need to:

  • use different arguments when arguing with politicians (for instance, the economic impact of wasting money on placebo-therapies, or the fact that systematically misinforming the public is highly unethical and counter-productive),
  • and make politicians understand science better than they do at present, perhaps even insist that ministers are experts in their respective areas (i. e. a minister of health fully understands the fundamental issues of healthcare).

Does that mean the new developments in the realm of French homeopathy are all doomed to failure?

No, I don’t think so – at least (and at last) we have a vocal group of doctors protesting against wasteful nonsense, and a fairly sound and accurate statement from a French minister of health:

HOMEOPATHY, IT’S PROBABLY A PLACEBO EFFECT!

 

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.

 

 

Chiropractic for kids? Yes, many chiropractors advocate (and earn good money with) it, yet it has been pointed out ad nauseam that the claim of being able of treating paediatric conditions is bogus (in fact, the BCA even lost a famous court case over this issue). But evidence does rarely seem to stop a chiro on a mission!

This website shows us how UK chiropractors plan to educate colleagues in ‘paediatric chiropractic’.

END OF QUOTE

The event is hosted and organised by the ‘United Chiropractic Association UK’ (UCA), an organisation with a mission to ensure the public has access to vitalistic chiropractic care, which claims that chiropractors provide care that is safe. Because the techniques used by chiropractors are acquired over years of study and experience, chiropractors have an enviable safety record. In fact, in the words of a classic New Zealand study, chiropractic care is “remarkably safe.” Chiropractors use the latest methods. After years of study, licensing examinations and continuing education seminars, chiropractors in the United Kingdom are at the top of their game, using proven techniques and natural methods to help you get well and stay well.

The UCA is firmly rooted in the gospel of the founding fathers (D D Palmer, B J Palmer etc.): Chiropractic is concerned with the preservation and restoration of health, and focuses particular attention on the subluxation. A subluxation is a complex of functional and/or structural and/or pathological articular changes that compromise neural integrity and may influence organ system function and general health. A subluxation is evaluated, diagnosed, and managed through the use of chiropractic procedures based on the best available rational and empirical evidence. Subluxation is a fundamental axiom of the Chiropractic profession. The World Federation of Chiropractors (WFC) policy statement reaffirms the use of the term vertebral subluxation and it is defined succinctly and accepted by the World Health Organisation (WHO).

Thus, the UCA seems to subscribe to both principles of the Palmers. The first is subluxation and the second is profit.

Now, now, now – I must not be so sarcastic.

Try something constructive, Edzard!

You are absolutely correct, Edzard.

Here it is, my constructive contribution to this event:

I herewith offer the UCA to give two lectures during their course; one about the importance of critical thinking in healthcare, and one reviewing the evidence for and against chiropractic for paediatric conditions.
