If you ever receive an email from ‘email@example.com’, please be aware that it is not from me. It comes from some clown who seems to want to pretend to be me.
How do I know? I received a short email from that very person. Here is its full text in all its beauty:
“You are the most bullshit person i know who claim to be a good doctor by putting other professions down. you are a killer because of your false information.”
What does that tell us about the identity of the author?
- He does not seem to be an admirer of my work.
- He feels strongly about something.
- He does not mince his words.
- He does not write very good English.
- He is not very well-informed [I do not think that I ever claimed to be a ‘good doctor’].
- He is factually wrong [I have not ever killed anyone for any reason].
What he presumably wants to express is that, in his view, the information I publish on this blog and perhaps elsewhere has the potential to kill patients. This is a somewhat disturbing assumption because the opposite is truly my intention.
It is a great pity that the author of these lines did not manage to be a little more specific.
- Does he [somehow, I presume the author is male] think that, by warning readers of all sorts of quackery and outright health fraud, I might kill someone?
- Does he believe that my repeated warnings about the lack of good evidence for alternative medicine drive patients into the arms of even more dangerous clinicians?
- Or is he just an unfortunate sufferer of a serious mental condition such as paranoia?
As I am totally in the dark here and cannot even begin to answer these questions, I will leave it to you, the readers of this post, to decide.
Or perhaps the author of this charming email wants to enlighten us?
The ‘INTERNATIONAL CHIROPRACTIC PEDIATRIC ASSOCIATION’ (ICPA) is, according to their website, ‘a nonprofit organization whose mission is to advance chiropractic by establishing evidence informed practice, supporting excellence in professional skills and delivering educational resources to the public. It fulfills this mission by engaging and serving family chiropractors worldwide through research, training and public education.’
It fulfils its mission by, amongst other things, tweeting links to other pro-chiropractic activities. It is via such a tweet that I recently found the Pathways to Family Wellness (PFW). This is a quarterly print and digital magazine whose mission is to support you and your family’s quest for wellness.
This sounds exciting, I thought, and decided to have a closer look. I found that, according to its website, the magazine ‘collaborates with consciousness leaders, cutting-edge scientists and researchers, families on their conscious path, holistic practitioners and dynamic non-profit organizations to bring the most current insights into wellness to our readers.’
The Executive Editor and Publisher of PFW is Dr. Jeanne Ohm. She has ‘practiced family wellness care since 1981 with her husband, Dr. Tom. They have six children who were all born at home and are living the chiropractic family wellness lifestyle. Ohm is an instructor, author, and innovator. Her passion is: training DC’s with specific techniques for care in pregnancy, birth & infancy, forming national alliances for chiropractors with like-minded perinatal practitioners, empowering mothers to make informed choices, and offering pertinent patient educational materials.’
My suspicion that this is an outlet of chiropractic nonsense is confirmed as I read an article by Bobby Doscher, D.C., N.D. on the subject of chiropractic treatment for children with neurological problems. The article itself is merely promotional and therefore largely irrelevant. But one short passage is interesting nevertheless, I thought:
Chiropractic Based on Scientific Fact
Since its beginning, chiropractic has been based on the scientific fact that the nervous system controls the function of every cell, tissue, organ and system of your body. While the brain is protected by the skull, the spinal cord is more vulnerable, covered by 24 moving vertebrae. When these bones lose their normal motion or position, they can irritate the nervous system. This disrupts the function of the tissues or organs these nerves control; this is called vertebral subluxation complex.
I thought this was as revealing as it was hilarious. Since such nonsensical notions are ubiquitous in the chiropractic literature, I am tempted to conclude that most chiropractors believe this sort of thing themselves. This makes them perhaps more honest but also more of a threat: sincere conviction renders a quack not less but more dangerous.
On the website of the Bristol University Hospital, it was just revealed that UK homeopathy seems to have suffered another blow:
“Homeopathic medicine has been available in Bristol since 1852, when Dr Black first started dispensing from premises in the Triangle. During the next 69 years the service developed and expanded culminating in the commissioning in 1921 of a new hospital in the grounds of Cotham House. The Bristol Homeopathic Hospital continued to provide a full range of services until 1986 when the in-patient facilities were transferred to the Bristol Eye Hospital, where they continue to be provided, and outpatient services were moved to the ground floor of the Cotham Hill site. In 1994, following the sale of the main building to the University by the Bristol and District Health Authority, a new purpose built Department was provided in the Annexe buildings of the main building, adjoining the original Cotham House. The NHS Homeopathic Service is now being delivered on behalf of University Hospital Bristol by the Portland Centre for Integrative Medicine (PCIM), a Community Interest Company.”
The Portland Centre for Integrative Medicine has joined Litfield House offering medical homeopathy with Dr Elizabeth Thompson. And this is how the new service is described [I have added references in the following unabridged quote in bold which refer to my comments below]:
Medical Homeopathy is a holistic  approach delivered by registered health care professionals that uses a low dose of an activated  natural  substance  to stimulate a self-healing response in the body . At the first appointment the doctor will take time to understand problem symptoms that might be physical, emotional or psychological and then a treatment plan will be discussed between the patient and the doctor , with homeopathic medicines chosen for you or your child on an individual basis.
WHAT CONDITIONS ARE SUITABLE FOR MEDICAL HOMEOPATHY?
Homeopathy can be safely  used to improve symptoms and well-being across a wide range of long term conditions: from childhood eczema  and ADHD ; to adults with medically unexplained conditions ; inflammatory bowel disease , cancer  or chronic fatigue syndrome ; and other medical conditions, including obesity  and depression . Some people use homeopathy to stay well  and others use it to help difficult symptoms and/ or the side effects of conventional treatments .
This looks like a fairly bland and innocent little advertisement at first glance. If we analyse it closer, however, we find plenty of misleading claims. Here are the ones that caught my eye:
- Homeopaths claim that their approach is holistic and thus aim at differentiating it from conventional health care. This is misleading because ALL good medicine is by definition holistic.
- Nothing is ‘activated’; homeopaths believe that succession releases the ‘vital force’ in a remedy – but this is little more than hocus-pocus from the dark ages of medicine.
- Nothing is natural about endlessly diluting and shaking a medicine, while pretending that this ritual renders it more active and effective. And nothing is natural about remedies such as ‘Berlin Wall’.
- It is misleading to speak about ‘substance’ in relation to homeopathic remedies, because they can be manufactured also from non-material stuff too; examples are remedies such as X-ray, sol [sun light] or lunar [moonlight].
- The claim that homeopathic remedies stimulate the self-healing properties of the body is pure phantasy.
- “The doctor will take time to understand problem symptoms that might be physical, emotional or psychological and then a treatment plan will be discussed between the patient and the doctor” – this also applies to any consultation with any health care practitioner.
- Homeopathy is not as safe as homeopaths try to make us believe; several posts on this blog have dealt with this issue.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- There is no good evidence to support this claim.
- True, some people use anything for anything; but there is no sound evidence to show that homeopathy is an effective prophylactic intervention for any disease.
- Nor is there good evidence that it is effective to “help difficult symptoms and/ or the side effects of conventional treatments”.
So, what we have here is a short paragraph which, on closer inspection, turns out to be full of misleading statements, bogus claims and dangerous lies. Not a good start for a new episode in the life of the now dramatically down-sized homeopathic clinic in Bristol, I’d say. And neither is it a publication of which the Bristol University Hospital can be proud. I suggest they correct it as a matter of urgency; otherwise they risk a barrage of complaints to the appropriate regulators by people who treasure the truth a little more than they seem to do themselves.
Recently an interesting article caught my eye. It was published in the official journal of the ‘Deutscher Zentralverein Homoeopathischer Aerzte’ (the professional body of German doctor homeopath which mostly acts as a lobby group). Unfortunately it is in German – but I will try to take you through what I believe to be the most important issue.
The article seems to have the aim to defame Natalie Grams, the homeopath who had the courage to change her mind about homeopathy and to even write a book about her transformation. This book impressed me so much that I wrote a post about it when it was first published. The book did, however, not impress her ex-colleagues. Consequently the book review by the German lobbyists is full of personal attacks and almost devoid of credible facts.
A central claim of the defamatory piece is that, contrary to what she claims in her book, homeopathy is supported by sound evidence. Here is the crucial quote: Meta-Analysen von Kleijnen (1991), Linde (1997), Cucherat (2000) und Mathie (2014) [liefern] allesamt positive Ergebnisse zur Wirksamkeit der Homöopathie… This translates as follows: meta-analyses of Kleijnen, Linde, Cucherat and Matie all provide positive results regarding the effectiveness of homeopathy. As this is a claim, we hear ad nauseam whenever we discuss the issue with homeopathy (in the UK, most homeopathic bodies and even the Queen’s homeopath, P Fisher, have issued very similar statements), it may be worth addressing it once and for all.
This paper was the result of an EU-funded project in which I was involved as well; I therefore know about it first hand. The meta-analysis itself is quite odd in that it simply averages the p-values of all the included studies and thus provides a new overall p-value across all trials. As far as I know, this is not an accepted meta-analytic method and seems rather a lazy way of doing the job. The man on our EU committee was its senior author, professor Boissel, who did certainly not present it to us as a positive result for homeopathy (even Peter Fisher who also was a panel member should be able to confirm this). What is more, the published conclusions are not nearly as positive as out lobbyists seem to think: ‘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.’
The meta-analysis by Linde et al seems to be the flag-ship in the homeopathic fleet. For those who don’t know it, here is its abstract in full:
BACKGROUND: Homeopathy seems scientifically implausible, but has widespread use. We aimed to assess whether the clinical effect reported in randomised controlled trials of homeopathic remedies is equivalent to that reported for placebo.
METHODS: We sought studies from computerised bibliographies and contracts with researchers, institutions, manufacturers, individual collectors, homeopathic conference proceedings, and books. We included all languages. Double-blind and/or randomised placebo-controlled trials of clinical conditions were considered. Our review of 185 trials identified 119 that met the inclusion criteria. 89 had adequate data for meta-analysis, and two sets of trial were used to assess reproducibility. Two reviewers assessed study quality with two scales and extracted data for information on clinical condition, homeopathy type, dilution, “remedy”, population, and outcomes.
FINDINGS: The combined odds ratio for the 89 studies entered into the main meta-analysis was 2.45 (95% CI 2.05, 2.93) in favour of homeopathy. The odds ratio for the 26 good-quality studies was 1.66 (1.33, 2.08), and that corrected for publication bias was 1.78 (1.03, 3.10). Four studies on the effects of a single remedy on seasonal allergies had a pooled odds ratio for ocular symptoms at 4 weeks of 2.03 (1.51, 2.74). Five studies on postoperative ileus had a pooled mean effect-size-difference of -0.22 standard deviations (95% CI -0.36, -0.09) for flatus, and -0.18 SDs (-0.33, -0.03) for stool (both p < 0.05).
INTERPRETATION: The results of our meta-analysis are not compatible with the hypothesis that the clinical effects of homeopathy are completely due to placebo. However, we found insufficient evidence from these studies that homeopathy is clearly efficacious for any single clinical condition. Further research on homeopathy is warranted provided it is rigorous and systematic.
Again, the conclusions are not nearly as strongly in favour of homeopaths as the German lobby group assumes. Moreover, this paper has been extensively criticised for a wide range of reasons which I shall not have to repeat here. However, one point is often over-looked: this is not an assessment of RCTs, it is an analysis of studies which were double-blind and/or randomised and placebo-controlled. This means that it includes trials that were not randomised and studies that were not double-blind.
But this is just by the way. What seems much more important is the fact that, in response to the plethora of criticism to their article, the same authors published a re-analysis of exactly the same data-set two years later. Having considered the caveats and limitations more carefully, they now concluded that ‘in the study set investigated, there was clear evidence that studies with better methodological quality tended to yield less positive results.’
It is most intriguing to see how homeopaths cite their ‘flagship’ on virtually every possible occasion, while forgetting that a quasi correction has been published which puts the prior conclusions in a very different light !
The much-cited article by Kleijnen is now far too old to be truly relevant. It includes not even half of the trials available today. But, for what it’s worth, here are Kleijnen’s conclusions: At the moment the evidence of clinical trials is positive but not sufficient to draw definitive conclusions because most trials are of low methodological quality and because of the unknown role of publication bias. This indicates that there is a legitimate case for further evaluation of homoeopathy, but only by means of well performed trials.
If the homeopathy lobby today proclaims that this paper constitutes proof of efficacy, they are in my view deliberately misleading the public.
The Mathie meta-analysis has been extensively discussed on this blog (see here and here). It is not an overall meta-analysis but merely evaluates the subset of those trials that employed individualised homeopathy. Crucially, it omits the two most rigorous studies which happen to be negative. Its conclusions are as follows: ‘Medicines prescribed in individualised homeopathy may have small, specific treatment effects. Findings are consistent with sub-group data available in a previous ‘global’ systematic review. The low or unclear overall quality of the evidence prompts caution in interpreting the findings. New high-quality RCT research is necessary to enable more decisive interpretation.’
Again, I would suggest that anyone who interprets this as stating that this provides ‘positive results regarding the effectiveness of homeopathy’ is not telling the truth.
MY CONCLUSIONS FROM ALL THIS:
- Some systematic reviews and meta-analyses do indeed suggest that the trial data are positive. However, they all caution that such a result might be false-positive.
- None of these papers provide anything near a proof for the effectiveness of homeopathy.
- Homeopathy has not been shown to be more than a placebo therapy.
- To issue statements to the contrary is dishonest.
Therapeutic touch (TT) is a popular ‘energy therapy’ which is based on the use of hand movements and detection of ‘energy field congestion’ to correct alleged imbalances that, in turn, are postulated to stimulate self-healing. The effectiveness of TT during radiotherapy for breast cancer is unknown, and this study was aimed at shedding some light on it.
Women undergoing adjuvant radiation for stage I/II breast cancer post surgery were recruited for this study. TT treatments were administered to patients in the experimental group three times per week following radiation therapy. The control group did not receive any TT. Both groups had conventional care in addition.
The effectiveness of TT was evaluated by documenting the ‘time to develop’ and the ‘worst grade of radiation’ dermatitis. Toxicity was assessed using NCIC CTC V3 dermatitis scale. Cosmetic rating was performed using the EORTC Breast Cosmetic Rating. The quality of life, mood and energy, and fatigue were assessed by EORTC QLQ C30, POMS, and BFI, respectively. The parameters were assessed at baseline, and serially during treatment.
A total of 49 patients entered the study (17 in the TT group and 32 in the control group). Median age in TT arm was 63 years and in control arm was 59 years. TT was considered feasible as all 17 patients screened completed TT treatment. There were no side effects observed with the TT treatments. In the TT group, the worst grade of radiation dermatitis was grade II in nine patients (53%). Median time to develop the worst grade was 22 days. In the control group, the worst grade of radiation dermatitis was grade III in 1 patient. However, the most common toxicity grade was II in 15 patients (47%). Three patients did not develop any dermatitis. Median time to develop the worst grade in the control group was 31 days. There was no difference between cohorts for the overall EORTC cosmetic score and there was no significant difference in before and after study levels in quality of life, mood and fatigue.
Based on these findings, the authors drew the following conclusions: This study is the first evaluation of TT in patients with breast cancer using objective measures. Although TT is feasible for the management of radiation induced dermatitis, we were not able to detect a significant benefit of TT on NCIC toxicity grade or time to develop the worst grade for radiation dermatitis. In addition, TT did not improve quality of life, mood, fatigue and overall cosmetic outcome.
Like all forms of ‘energy healing’, TT lacks any biological plausibility and is not clinically effective. At best, it can generate a placebo-response; but in this particular study it did not even manage that.
Is it not time to stop fooling patients with outright quackery?
Is it not time to stop spending scarce research resources on such nonsense?
Is it not time that editors stop considering such rubbish for publication?
Is it not time to stop allowing TT-proponents to undermine rationality?
Is it not time to make progress and move on?
An Indian chain of homeopathic clinics, Dr Batra’s, has just opened its first branch in London. The new website is impressive. It claims homeopathy is effective for the following conditions:
Hair loss? Are they serious? Have they not seen pictures of Samuel Hahnemann?
I decided to look into the psoriasis claim a little closer. This is what they state regarding the homeopathic treatment of psoriasis:
Research-based evidences speak clear and loud of the success of homeopathy in treating psoriasis.
A study published in the Journal of the European Academy of Dermatology and Venereology, a conventional medical Journal, showed that psoriasis patients experienced significant improvement in their quality of life and reduction in their psoriasis symptoms with homeopathy. And this was without any kind of side-effects whatsoever. Of the 82 patients involved in the study that went on for 2 years, many had suffered psoriasis for as long as 15 years and had previously unsuccessfully tried conventional treatments.
At Dr. Batra’s we have successfully treated more than 25,000 cases of psoriasis with homeopathy over the last 35 years. Our safe and scientific solutions have brought smiles to many suffering patients of psoriasis. In fact, a study conducted by A.C. Nielson showed that as compared to general practitioners, specialists and local homeopaths, a higher than average improvement is seen at Dr. Batra’s in treatment of skin ailments.
To the reader who does not look deeper, this may sound fairly convincing. Sadly, it is not. The first study cited above was an uncontrolled trial. Here is its abstract:
Design Prospective multicentre observational study. Objective To evaluate details and effects of homeopathic treatment in patients with psoriasis in usual medical care. Methods Primary care patients were evaluated over 2 years using standardized questionnaires, recording diagnoses and complaints severity, health-related quality of life (QoL), medical history, consultations, all treatments, and use of other health services. Results Forty-five physicians treated 82 adults, 51.2% women, aged 41.6 +/- 12.2 (mean +/- SD) years. Patients had psoriasis for 14.7 +/- 11.9 years; 96.3% had been treated before. Initial case taking took 127 +/- 47 min. The 7.4 +/- 7.4 subsequent consultations (duration: 19.4 +/- 10.5 min) cumulated to 169.0 +/- 138.8 min. Patients received 6.0 +/- 4.9 homeopathic prescriptions. Diagnoses and complaints severity improved markedly with large effect sizes (Cohen’s d= 1.02-2.09). In addition, QoL improved (SF-36 physical component score d = 0.26, mental component score d = 0.49), while conventional treatment and health service use were considerably reduced. Conclusions Under classical homeopathic treatment, patients with psoriasis improved in symptoms and QoL.
It is clear that, due to the lack of a control group, no causal inference can be made between the treatment and the outcome. To claim that otherwise is in my view bogus.
I should mention that there is not a single controlled clinical trial of homeopathy for psoriasis that would support the claim that it is effective.
The second study is not listed in Medline. In fact, the only publication of an author by the name of ‘A C Nielson’ is entitled ‘Are men more intuitive when it comes to eating and physical activity?’. Until I see the evidence, I very much doubt that the study cited above produced strong evidence that homeopathy is an effective cure for psoriasis.
Dr Batra’s chain of clinics boasts to provide the best quality and the highest standards of services that percolate down to all levels in an organisation. Everyone in the institute and those associated with it strive for excellence in whatever they do. Measuring the degree of customer satisfaction was the fundamental concept on which this homeopathic institute’s commitment to become a patient-driven institution was built.
Nice words! SHAME THAT THEY HAVE DECIDED TO DILUTE THEIR TRUTH HOMEOPATHICALLY!
The question why patients turn to homeopathy – or indeed any other disproven treatment – has puzzled many people. There has been a flurry of research into these issues. Here is the abstract of a paper that I find very remarkable and truly fascinating:
Interviews with 100 homeopathic patients in the San Francisco Bay Area show that for the most part the patients are young, white and well-educated, and have white-collar jobs; most had previously tried mainstream medical care and found it unsatisfactory. Among the reasons for their dissatisfaction were instances of negative side effects from medication, lack of nutritional or preventive medical counseling, and lack of health education. Experiences with conventional physicians were almost evenly divided: nearly half of the subjects reported poor experiences, slightly fewer reported good experiences. Three quarters of the patients suffered from chronic illness and about half considered their progress to be good under homeopathic care. The majority were simultaneously involved in other nontraditional health care activities.
If you read the full article, you will see that the authors make further important points:
- Patients who use alternative treatments are by no means ignorant or unsophisticated.
- Most of these patients use other treatments in parallel – but they seem to attribute any improvements in their condition to homeopathy.
- Dissatisfaction with conventional medicine seems the prime motivation to turn to homeopathy. In particular, patients need more time with their clinician and want to share the responsibility for their own health – and these needs are met by homeopaths better than by conventional doctors.
- Most homeopaths (63%) adhere to Hahnemann’s dictum that homeopathic remedies must never be combined with other treatments. This renders then potentially dangerous in many situations.
At this point you might say BUT WE KNEW ALL THIS BEFORE! True! Why then do I find this paper so remarkable?
It is remarkable mostly because of its publication date: 1978! In fact, it may well be the very first of hundreds of similar surveys that followed in the years since.
The questions I ask myself are these:
- IF WE KNEW ALL THIS SINCE ALMOST 40 YEARS, WHY HAVE WE NOT DONE MORE ABOUT IT?
- WHY ARE WE SO UNSUCCESSFUL IN GETTING THE FACTS THROUGH TO OUR PATIENTS?
- WHY HAVE WE NOT MANAGED TO IMPROVE CONVENTIONAL MEDICINE SUCH THAT PATIENTS STOP CONSULTING QUACKS?
- WHY ARE WE STILL CONDUCTING SURVEY AFTER SURVEY WHEN THE EMBARRASSING FACTS ARE PLAIN TO SEE?
Wet cupping is a therapy traditionally used in several cultures. It involves superficial injuries to the skin and subsequently the application of a vacuum cup over the injured site. This procedure would draw a small amount of blood into the cup, and this visible effect was taken as a sign that the humors or life forces or whatever are being restored.
The treatment is obviously painful and carries the risk of infection. But does it work? There are not many clinical trials of this form of alternative medicine, and I was therefore thrilled to find a new paper with a randomised clinical trial.
The aim of this clinical trial was to evaluate the effectiveness and safety of wet cupping therapy as the sole treatment for persistent nonspecific low back pain (PNSLBP). The investigators recruited 80 with PNSLBP lasting at least 3 months and randomly allocated them to an intervention group (n=40) or to a control group (n=40). The experimental group had 6 wet cupping sessions within 2 weeks, each of which were done at two bladder meridian (BL) acupuncture points. The control group had no such treatments. Acetaminophen was allowed as a rescue treatment in both groups. The Numeric Rating Scale (NRS), McGill Present Pain Intensity (PPI), and Oswestry Disability Questionnaire (ODQ) were used as outcome measures. Numbers of acetaminophen tablets taken were compared at 4 weeks from baseline. Adverse events were recorded.
At the end of the intervention, statistically significant differences in all three outcome measures favouring the wet cupping group compared with the control group were seen. These improvements continued for another two weeks after the end of the intervention. Acetaminophen was used less in the wet cupping group, but this difference was not statistically significant. No adverse events were reported.
The authors concluded that wet cupping is potentially effective in reducing pain and improving disability associated with PNSLBP at least for 2 weeks after the end of the wet cupping period. Placebo-controlled trials are needed.
Every now and then – well, actually in alternative medicine this is not so rare an event – I come across a study that ‘smells to high heaven’. This one certainly does; to be precise, it has the stench of TOO GOOD TO BE TRUE.
Apart from the numerous weaknesses of the study design, there is the fact that the results are do simply not seem plausible. Low back pain has a natural history that is well-studied. We therefore know that the majority of cases do get better fairly quickly regardless of whether we treat them or not. In this study, the control group did not improve at all, as shown on the impressive graph below (the grey line depicts the symptoms in the control group and the black one those of the cupping group).
To me, the improvement of the experimental group looks much like one might expect from the natural history of back pain. If this were true, the effect of wet cupping would by close to zero and the conclusion drawn by the authors of this trial would be false-positive.
But why was there no improvement in the control group?
I do not know the answer to this question. All I know is that it is this unexplained phenomenon which has created the impression of effectiveness of wet cupping.
This seems to be the question that occupies the minds of several homeopaths.
So was I!
Let me explain.
In 1997, Linde et al published their now famous meta-analysis of clinical trials of homeopathy which concluded that “The results of our meta-analysis are not compatible with the hypothesis that the clinical effects of homeopathy are completely due to placebo. However, we found insufficient evidence from these studies that homeopathy is clearly efficacious for any single clinical condition. Further research on homeopathy is warranted provided it is rigorous and systematic.”
This paper had several limitations which Linde was only too happy to admit. The authors therefore conducted a re-analysis which, even though published in an excellent journal, is rarely cited by homeopaths. Linde et al stated in their re-analysis of 2000: “there was clear evidence that studies with better methodological quality tended to yield less positive results.” It was this phenomenon that prompted me and my colleague Max Pittler to publish a ‘letter to the editor’ which now – 15 years later – seems the stone of homeopathic contention.
A blog-post by a believer in homeopathy even asks the interesting question: Did Professor Ernst Sell His Soul to Big Pharma? It continues as follows:
Edzard Ernst is an anti-homeopath who spent his career attacking traditional medicine. In 1993 he became Professor of Complementary Medicine at the University of Exeter. He is often described as the first professor of complementary medicine, but the title he assumed should have fooled no-one. His aim was to discredit medical therapies, notably homeopathy, and he then published some 700 papers in ‘scientific’ journals to do so.
Now, Professor Robert Hahn, in his blog, has made an assessment of the quality of his work… In the interests of the honesty and integrity in science, it is an important assessment. It shows, in his view, how science has been taken over by ideology (or as I would suggest, more accurately, the financial interests of Big Corporations, in this case, Big Pharma). The blog indicates that in order to demonstrate that homeopathy is ineffective, over 95% of scientific research into homeopathy has to be discarded or removed!
So for those people who, like myself, cannot read the original German, here is an English translation of the blog…
“I have never seen a science writer so blatantly biased as Edzard Ernst: his work should not be considered of any worth at all, and discarded” finds Sweden’s Professor Robert Hahn, a leading medical scientist, physician, and Professor of Anaesthesia and Intensive Care at the University of Linköping, Sweden.
Hahn determined therefore to analyze for himself the ‘research’ which supposedly demonstrated homeopathy to be ineffective, and reached the shocking conclusion that:
“only by discarding 98% of homeopathy trials and carrying out a statistical meta-analysis on the remaining 2% negative studies, can one ‘prove’ that homeopathy is ineffective”.
In other words, all supposedly negative homeopathic meta-analyses which opponents of homeopathy have relied on, are scientifically bogus…
Who can you trust? We can begin by disregarding Edzard Ernst. I have read several other studies that he has published, and they are all untrustworthy. His work should be discarded…
In the case of homeopathy, one should stick with what the evidence reveals. And the evidence is that only by removing 95-98% of all studies is the effectiveness of homeopathy not demonstrable…
So, now you are wondering, I am sure: HOW MUCH DID HE GET FOR SELLING HIS SOUL TO BIG PHARMA?
No? You are wondering 1) who this brilliant Swedish scientist, Prof Hahn, is and 2) what article of mine he is criticising? Alright, I will try to enlighten you.
Here I can rely on a comment posted on my blog some time ago by someone who can read Swedish (thank you Bjorn). He commented about Hahn as follows:
A renowned director of medical research with well over 300 publications on anesthesia and intensive care and 16 graduated PhD students under his mentorship, who has been leading a life on the side, blogging and writing about spiritualism, and alternative medicine and now ventures on a public crusade for resurrecting the failing realm of homeopathy!?! Unbelievable!
I was unaware of this person before, even if I have lived and worked in Sweden for decades.
I have spent the evening looking up his net-track and at his blog at roberthahn.nu (in Swedish).
I will try to summarise some first impressions:
Hahn is evidently deeply religious and there is the usual, unmistakably narcissistic aura over his writings and sayings. He is religiously confident that there is more to this world than what can be measured and sensed. In effect, he seems to believe that homeopathy (as well as alternative medical methods in general) must work because there are people who say they have experienced it and denying the possibility is akin to heresy (not his wording but the essence of his writing).
He has, along with his wife, authored at least three books on spiritual matters with titles such as (my translations) “Clear replies from the spiritual world” and “Connections of souls”.
He has a serious issue with skeptics and goes on at length about how they are dishonest bluffers[sic] who willfully cherry-pick and misinterpret evidence to fit their preconceived beliefs.
He feels that desperate patients should generally be allowed the chance that alternative methods may offer.
He believes firmly in former-life memories, including his own, which he claims he has found verification for in an ancient Italian parchment.
His main arguments for homeopathy are Claus Linde’s meta analyses and the sheer number of homeopathic research that he firmly believes shows it being superior to placebo, a fact that (in his opinion) shows it has a biological effect. Shang’s work from 2005 he dismisses as seriously flawed.
He also points to individual research like this as credible proof of the biologic effect of remedies.
He somewhat surprisingly denies recommending homeopathy despite being convinced of its effect and maintains that he wants better, more problem oriented and disease specific studies to clarify its applicability. (my interpretation)
If it weren’t for his track record of genuine, acknowledged medical research and him being a renowned authority in a genuine, scientific medical field, this man would be an ordinary, religiously devout quack.
What strikes me as perhaps telling of a consequence of his “exoscientific” activity, is that Hahn, who holds the position of research director at a large city trauma and emergency hospital is an “adjungerad professor”, which is (usually) a part time, time limited, externally financed professorial position, while any Swedish medical doctor with his very extensive formal merits would very likely hold a full professorship at an academic institution.

MY 2000 PAPER THAT SEEMS TO IRRITATE HAHN
This was a short ‘letter to the editor’ by Ernst and Pittler published in the J Clin Epidemiol commenting on the above-mentioned re-analysis by Linde et al which was published in the same journal. As its text is not available on-line, I re-type parts of it here:
In an interesting re-analysis of their meta-analysis of clinical trials of homeopathy, Linde et al conclude that there is no linear relationship between quality scores and study outcome. We have simply re-plotted their data and arrive at a different conclusion. There is an almost perfect correlation between the odds ratio and the Jadad score between the range of 1-4… [some technical explanations follow which I omit]…Linde et al can be seen as the ultimate epidemiological proof that homeopathy is, in fact, a placebo.
And that is, as far as I can see, the whole mysterious story. I cannot even draw a conclusion – all I can do is to ask a question:
DOES ANYONE UNDERSTAND WHAT THEY ARE GOING ON ABOUT?
We used to call it ‘alternative medicine’ (on this blog, I still do so, because I believe it is a term as good or bad as any other and it is the one that is easily recognised); later some opted for ‘complementary medicine’; since about 15 years a new term is en vogue: INTEGRATED MEDICINE (IM).
Supporters of IM are adamant that IM is not synonymous with the other terms. But how is IM actually defined?
One of IM’s most prominent defenders is, of course Prince Charles. In his 2006 address to the WHO, he explained: “We need to harness the best of modern science and technology, but not at the expense of losing the best of what complementary approaches have to offer. That is integrated health – it really is that simple.”
Perhaps a bit too simple?
There are several more academic definitions, and it seems that, over the years, IM-fans have been busy moving the goal post quite a bit. The original principle of ‘THE BEST OF BOTH WORLDS’ has been modified considerably.
- IM is a “comprehensive, primary care system that emphasizes wellness and healing of the whole person…” [Arch Intern Med. 2002;162:133-140]
- IM “views patients as whole people with minds and spirits as well as bodies and includes these dimensions into diagnosis and treatment.” [BMJ. 2001; 322:119-120]
During my preparations for my lecture at the 16th European Sceptics Congress in London last week (which was on the subject of IM), I came across a brand-new (September 2015) definition. It can be found on the website of the COLLEGE OF MEDICINE This Michael Dixon-led organisation can be seen as the successor of Charles’ ill-fated FOUNDATION FOR INTEGRATED HEALTH; it was originally to be called COLLEGE FOR INTEGRATED MEDICINE. We can therefore assume that they know best what IM truly is or aspires to be. The definition goes as follows:
IM is a holistic, evidence-based approach which makes intelligent use of all available therapeutic choices to achieve optimal health and resilience for our patients.
This may sound good to many who are not bothered or unable to think critically. It oozes political correctness and might therefore even impress some politicians. But, on closer scrutiny, it turns out to be little more than offensive nonsense. I feel compelled to publish a short analysis of it. I will do this by highlighting and criticising the important implications of this definition one by one.
1) IM is holistic
Holism has always been at the core of any type of good health care. To state that IM is holistic misleads people into believing that conventional medicine is not holistic. It also pretends that medicine might become more holistic through the addition of some alternative modalities. Yet I cannot imagine anything less holistic than diagnosing patients by merely looking at their iris (iridology) or assuming all disease stems from subluxations of the spine (chiropractic), for example. This argument is a straw-man, if there ever was one.
2) IM is evidence-based
This assumption is simply not true. If we look what is being used under the banner of IM, we find no end of treatments that are not supported by good evidence, as well as several for which the evidence is squarely negative.
3) IM is intelligent
If it were not such a serious matter, one could laugh out loud about this claim. Is the implication here that conventional medicine is not intelligent?
4) IM uses all available therapeutic choices
This is the crucial element of this definition which allows IM-proponents to employ anything they like. Do they seriously believe that patients should have ALL AVAILABLE treatments? I had thought that responsible health care is about applying the most effective therapies for the condition at hand.
5) IM aims at achieving optimal health
Another straw-man; it implies that conventional health care professionals do not want to restore their patients to optimal health.
In my lecture, which was not about this definition but about IM in general, I drew the following six conclusions:
- Proponents of IM mislead us with their very own, nonsensical terminology and definitions.
- They promote two main principles: use of quackery + holism.
- Holism is at the heart of all good medicine; IM is at best an unnecessary distraction.
- Using holism to promote quackery is dishonest and counter-productive.
- The integration of quackery will render healthcare not better but worse.
- IM flies in the face of common sense and medical ethics; it is a disservice to patients.
