medical ethics

Adults using unproven treatments is one thing; if kids do it because they are told to, that is quite another thing. Children are in many ways more vulnerable than grown-ups and they usually cannot give fully informed consent. It follows that the use of such treatments for kids can be a delicate and complex matter.

A recent systematic review was aimed at summarizes the international findings for prevalence and predictors of complementary and alternative medicine (CAM) use among children/adolescents. The authors systematically searched 4 electronic databases (PubMed, Embase, PsycINFO, AMED; last update in 07/2013) and reference lists of existing reviews and all included studies. Publications without language restriction reporting patterns of CAM utilization among children/adolescents without chronic conditions were selected for inclusion. The prevalence rates for overall CAM use, homeopathy, and herbal drug use were extracted with a focus on country and recall period (lifetime, 1 year, current use). As predictors, the authors extracted socioeconomic factors, child‘s age, and gender.

Fifty-eight studies from 19 countries could be included in the review. There were strong variations regarding study quality. Prevalence rates for overall CAM use ranged from 10.9 – 87.6 % for lifetime use, and from 8 – 48.5 % for current use. The respective percentages for homeopathy (highest in Germany, United Kingdom, and Canada) ranged from 0.8 – 39 % (lifetime) and from 1 – 14.3 % (current). Herbal drug use (highest in Germany, Turkey, and Brazil) was reported for 0.8 – 85.5 % (lifetime) and 2.2 – 8.9 % (current) of the children/adolescents. Studies provided a relatively uniform picture of the predictors of overall CAM use: higher parental income and education, older children. But only a few studies analyzed predictors for single CAM modalities.

The authors drew the following conclusion: CAM use is widespread among children/adolescents. Prevalence rates vary widely regarding CAM modality, country, and reported recall period.

In 1999, I published a very similar review; at the time, I found just 10 studies. Their results suggested that the prevalence of CAM use by kids was variable but generally high. CAM was often perceived as helpful. Insufficient data existed about safety and cost. Today, the body of surveys monitoring CAM use by children seems to have grown almost six-fold, and the conclusions are still more or less the same – but have we made progress in answering the most pressing questions? Do we know whether all these CAM treatments generate more good than harm for children?

Swiss authors recently published a review of Cochrane reviews which might help answering these important questions. They performed a synthesis of all Cochrane reviews published between 1995 and 2012 in paediatrics that assessed the efficacy, and clinical implications and limitations of CAM use in children. Main outcome variables were: percentage of reviews that concluded that a certain intervention provides a benefit, percentage of reviews that concluded that a certain intervention should not be performed, and percentage of studies that concluded that the current level of evidence is inconclusive.

A total of 135 reviews were included – most from the United Kingdom (29/135), Australia (24/135) and China (24/135). Only 5/135 (3.7%) reviews gave a recommendation in favour of a certain intervention; 26/135 (19.4%) issued a conditional positive recommendation, and 9/135 (6.6%) reviews concluded that certain interventions should not be performed. Ninety-five reviews (70.3%) were inconclusive. The proportion of inconclusive reviews increased during three, a priori-defined, time intervals (1995-2000: 15/27 [55.6%]; 2001-2006: 33/44 [75%]; and 2007-2012: 47/64 [73.4%]). The three most common criticisms of the quality of the studies included were: more research needed (82/135), low methodological quality (57/135) and small number of study participants (48/135).

The Swiss authors concluded that given the disproportionate number of inconclusive reviews, there is an ongoing need for high quality research to assess the potential role of CAM in children. Unless the study of CAM is performed to the same science-based standards as conventional therapies, CAM therapies risk being perpetually marginalised by mainstream medicine.

And what about the risks?

To determine the types of adverse events associated with the use of CAM that come to the attention of Australian paediatricians. Australian researchers conducted a monthly active surveillance study of CAM-associated adverse events as reported to the Australian Paediatric Surveillance Unit between January 2001 and December 2003. They found 39 reports of adverse events associated with CAM use, including four reported deaths. Reports highlighted several areas of concern, including the risks associated with failure to use conventional medicine, the risks related to medication changes made by CAM practitioners and the significant dangers of dietary restriction. The reported deaths were associated with a failure to use conventional medicine in favour of a CAM therapy.

These authors concluded that CAM use has the potential to cause significant morbidity and fatal adverse outcomes. The diversity of CAM therapies and their associated adverse events demonstrate the difficulty addressing this area and the importance of establishing mechanisms by which adverse effects may be reported or monitored.

So, we know that lots of children are using CAMs because their parents want them to. We also know that most of the CAMs used for childhood conditions are not based on sound evidence. The crucial question is: can we be sure that CAM for kids generates more good than harm? I fear the answer is a clear and worrying NO.

Getting good and experienced lecturers for courses is not easy. Having someone who has done more research than most working in the field and who is internationally known, might therefore be a thrill for students and an image-boosting experience of colleges. In the true Christmas spirit, I am today making the offer of being of assistance to the many struggling educational institutions of alternative medicine .

A few days ago, I tweeted about my willingness to give free lectures to homeopathic colleges (so far without response). Having thought about it a bit, I would now like to extend this offer. I would be happy to give a free lecture to the students of any educational institution of alternative medicine. I suggest to

  • do a general lecture on the clinical evidence of the 4 major types of alternative medicine (acupuncture, chiropractic, herbal medicine, homeopathy) or
  • give a more specific lecture with in-depth analyses of any given alternative therapy.

I imagine that most of the institutions in question might be a bit anxious about such an idea, but there is no need to worry: I guarantee that everything I say will be strictly and transparently evidence-based. I will disclose my sources and am willing to make my presentation available to students so that they can read up the finer details about the evidence later at home. In other words, I will do my very best to only transmit the truth about the subject at hand.

Nobody wants to hire a lecturer without having at least a rough outline of what he will be talking about – fair enough! Here I present a short summary of the lecture as I envisage it:

  • I will start by providing a background about myself, my qualifications and my experience in researching and lecturing on the matter at hand.
  • This will be followed by a background on the therapies in question, their history, current use etc.
  • Next I would elaborate on the main assumptions of the therapies in question and on their biological plausibility.
  • This will be followed by a review of the claims made for the therapies in question.
  • The main section of my lecture would be to review the clinical evidence regarding the efficacy of therapies in question. In doing this, I will not cherry-pick my evidence but rely, whenever possible, on authoritative systematic reviews, preferably those from the Cochrane Collaboration.
  • This, of course, needs to be supplemented by a review of safety issues.
  • If wanted, I could also say a few words about the importance of the placebo effect.
  • I also suggest to discuss some of the most pertinent ethical issues.
  • Finally, I would hope to arrive at a few clear conclusions.

You see, all is entirely up to scratch!

Perhaps you have some doubts about my abilities to lecture? I can assure you, I have done this sort of thing all my life, I have been a professor at three different universities, and I will probably manage a lecture to your students.

A final issue might be the costs involved. As I said, I would charge neither for the preparation (this can take several days depending on the exact topic), nor for the lecture itself. All I would hope for is that you refund my travel (and, if necessary over-night) expenses. And please note: this is  time-limited: approaches will be accepted until 1 January 2015 for lectures any time during 2015.

I can assure you, this is a generous offer  that you ought to consider seriously – unless, of course, you do not want your students to learn the truth!

(In which case, one would need to wonder why not)

A German homeopathic journal, Zeitschrift Homoeopathie, has just published the following interesting article entitled HOMEOPATHIC DOCTORS HELP IN LIBERIA. It provides details about the international team of homeopaths that travelled to Liberia to cure Ebola. Here I take the liberty of translating it from German into English. As most of it is fairly self-explanatory, I abstain from any comments of my own – however, I am sure that my readers will want to add their views.

In mid-October, an international team of 4 doctors travelled to the West African country for three weeks. The mission in a hospital in Ganta, a town with about 40 000 inhabitants on the border to Guinea, ended as planned on 7 November. The exercise was organised by the World Association of Homeopathic Doctors, the Liga Medicorum Homoeopathica Internationalis (LMHI), with support of by the German Central Association of Homeopathic Doctors. The aim was to support the local doctors in the care of the population and, if possible, also to help in the fight against the Ebola epidemic. The costs for the three weeks’ stay were financed mostly through donations from homeopathic doctors.

“We know that we were invited mainly as well-trained doctors to Liberia, and that or experience in homeopathy was asked for only as a secondary issue”, stresses Cornelia Bajic, first chairperson of the DZVhA (German Central Association of Homeopathic Doctors). The doctors from India, USA, Switzerland and Germany were able to employ their expertise in several wards of the hospital, to help patients, and to support their Liberian colleagues. It was planned to use and document the homeopathic treatment of Ebola-patients as an adjunct to the WHO prescribed standard treatment. “Our experience from the treatment of other epidemics in the history of medicine allows the conclusion that a homeopathic treatment might significantly reduce the mortality of Ebola patients”, judges Bajic. The successful use of homeopathic remedies has been documented for example in Cholera, Diphtheria or Yellow Fever.

Overview of the studies related to the homeopathic treatment of epidemics

In Ganta, the doctors of the LMHI team treated patients with “at times most serious diseases, particularly inflammatory conditions, children with Typhus, meningitis, pneumonias, and unclear fevers – each time only under the supervision of the local doctor in charge”, reports Dr Ortrud Lindemann, who also worked obstetrically in Ganta. The medical specialist reports after her return: “When we had been 10 days in the hospital, the successes had become known, and the patients stood in queues to get treated by us.” The homeopathic doctors received thanks from the Ganta hospital for their work, it was said that it had been helpful for the patients and a blessing for the employees of the hospital.


This first LMHI team of doctors was forbidden to care for patients from the “Ebola Treatment Unit”. The decision was based on an order of the WHO. A team of Cuban doctors was also waiting in vain for being allowed to work. “We are dealing here with a dangerous epidemic and a large number of seriously ill patients. And despite a striking lack of doctors in West Africa political considerations are more important than the treatment of these patients”, criticises the DZVhA chairperson Bajic. Now a second team is to travel to Ganta to support the local doctors.

I recently tweeted the following short text: “THIS IS HOW HOMEOPATHY CAN KILL MILLIONS” and provided a link to a website where a homeopaths advocated using homeopathy to control blood sugar levels in diabetic patients. The exact text I objected to is reproduced below:

“Management of Blood sugar

The commonly used remedies are Uranium Nitricum, Phosphoric Acid, Syzygium Jambolanum, Cephalandra Indica etc. These are classical Homeopathic remedies. These are used in physiologically active doses such as Mother tincture, 3x etc. depending up on the level of the blood sugar and the requirement of the patient. Several pharmaceutical companies have also brought in propriety medicines with a combination of the few Homeopathic medicines. Biochemic remedies which is a part of Homeopathy advocates Biocombination No 7 as a specific for Diabetes. Another Biochemic medicine Natrum Phos 3x is widely used with a reasonable success in controlling the blood sugar. Scientific studies on the impact of homeopathic medicines in bringing down blood sugar are limited, but many of the above remedies have some positive effects either as a stand-alone remedy or as an adjunct along with other medications.”

A clearly annoyed homeopath responded by tweeting: “homeopathy has been a favorite complement to diabetes treatment for over 200 yrs. Your evidence of the contrary is?”

So I better explain to her what I mean, and as this cannot be done in 140 characters, I do it with this post instead.

The claim expressed on the website is not that homeopathy can complement diabetes treatment; the claim is clearly that it can be a sole treatment and a replacement of conventional anti-diabetic treatment. There is, of course, no evidence at all for that. If patients put this claim to the test, many will die. Because there are many millions of diabetics worldwide, this claim has the potential to kill millions. In other words, my initial tweet was perhaps blunt but certainly correct.

Now to the notion of homeopathy as a ‘complement to diabetes treatment': do I have evidence to the contrary? I think that is entirely the wrong question. The true question here is whether homeopaths who claim that homeopathic remedies can be an effective adjunct to conventional anti-diabetic treatments have any evidence for their claim (after all, in health care, as in most other walks of life, it is the one who makes a claim who has to prove it, not the one who doubts it!). So, is there good evidence?

To the best of my knowledge, the answer is NO!

If you disagree, please show me the evidence.

If you have diabetes, chances are that you need life-long treatment. Before effective anti-diabetic medications became available, diabetes amounted to a death sentence. Fortunately, these times are long gone.

…unless, of course, you decide to listen to the promises of alternative practitioners many of whom offer a cure for diabetes. Here is just one website of hundreds that does just that. The following is an abbreviated quote where I have changed nothing, not even the numerous spelling mistakes:

Modern medicine has no  permanent cure for diabetes but alternative medicines like yoga ,mudra,ayurveda is very useful to control and even cure diabetes.Ayurveda is an alternative medicine to cure diabetes.

Alternative medicine like ayurveda is a best to cure diabetes naturally.
A serious disorder of the glands,of pancreas to be exact,is diabetes,or madhumeha as described in ayurveda.It is one of the most insidious disorders of the metabolism and,if left undiagnosed or untreated,it may lead to rapid emaciation and ultimately death…
Ayurveda medicines to cure diabetes
In ayurveda the following medicines have been recommended for this disease
Shiljita ————————–240 mg
Nyagrodadhi churna ———3 gm
These should be given twice after meals with decoction of arni.
Vasantakusumakara rasa —120 mg
Shudha Shilajit ————–240 mg
Nag Bhasma —————–120 mg
Haldi ————————–500 mg
Amlaki Churna ————-500 mg
Twice daily with powder of rose-apple stones.Twice daily with honey.
Chadraprabha  Vati ——– 500 mg
Mudra the alternative treatment to cure diabetes naturally
Mudra is a non medical and no cost treatment to cure diabetes.You can perform mudras at any time or any position.It is an effective way of treatment you can get better result if you practice it regularly .

It goes without saying that none of these treatments would cure diabetes. A Cochrane review concluded that there is insufficient evidence at present to recommend the use of these interventions in routine clinical practice. It also goes without saying that not many patients would fall for the nonsense proclaimed on this or so many other websites. But even just one single patient dying because of some charlatan promising a cure for life-threatening diseases is one patient too many.

Rigorous research into the effectiveness of a therapy should tell us the truth about the ability of this therapy to treat patients suffering from a given condition — perhaps not one single study, but the totality of the evidence (as evaluated in systematic reviews) should achieve this aim. Yet, in the realm of alternative medicine (and probably not just in this field), such reviews are often highly contradictory.

A concrete example might explain what I mean.

There are numerous systematic reviews assessing the effectiveness of acupuncture for fibromyalgia syndrome (FMS). It is safe to assume that the authors of these reviews have all conducted comprehensive searches of the literature in order to locate all the published studies on this subject. Subsequently, they have evaluated the scientific rigor of these trials and summarised their findings. Finally they have condensed all of this into an article which arrives at a certain conclusion about the value of the therapy in question. Understanding this process (outlined here only very briefly), one would expect that all the numerous reviews draw conclusions which are, if not identical, at least very similar.

However, the disturbing fact is that they are not remotely similar. Here are two which, in fact, are so different that one could assume they have evaluated a set of totally different primary studies (which, of course, they have not).

One recent (2014) review concluded that acupuncture for FMS has a positive effect, and acupuncture combined with western medicine can strengthen the curative effect.

Another recent review concluded that a small analgesic effect of acupuncture was present, which, however, was not clearly distinguishable from bias. Thus, acupuncture cannot be recommended for the management of FMS.

How can this be?

By contrast to most systematic reviews of conventional medicine, systematic reviews of alternative therapies are almost invariably based on a small number of primary studies (in the above case, the total number was only 7 !). The quality of these trials is often low (all reviews therefore end with the somewhat meaningless conclusion that more and better studies are needed).

So, the situation with primary studies of alternative therapies for inclusion into systematic reviews usually is as follows:

  • the number of trials is low
  • the quality of trials is even lower
  • the results are not uniform
  • the majority of the poor quality trials show a positive result (bias tends to generate false positive findings)
  • the few rigorous trials yield a negative result

Unfortunately this means that the authors of systematic reviews summarising such confusing evidence often seem to feel at liberty to project their own pre-conceived ideas into their overall conclusion about the effectiveness of the treatment. Often the researchers are in favour of the therapy in question – in fact, this usually is precisely the attitude that motivated them to conduct a review in the first place. In other words, the frequently murky state of the evidence (as outlined above) can serve as a welcome invitation for personal bias to do its effect in skewing the overall conclusion. The final result is that the readers of such systematic reviews are being misled.

Authors who are biased in favour of the treatment will tend to stress that the majority of the trials are positive. Therefore the overall verdict has to be positive as well, in their view. The fact that most trials are flawed does not usually bother them all that much (I suspect that many fail to comprehend the effects of bias on the study results); they merely add to their conclusions that “more and better trials are needed” and believe that this meek little remark is sufficient evidence for their ability to critically analyse the data.

Authors who are not biased and have the necessary skills for critical assessment, on the other hand, will insist that most trials are flawed and therefore their results must be categorised as unreliable. They will also emphasise the fact that there are a few reliable studies and clearly point out that these are negative. Thus their overall conclusion must be negative as well.

In the end, enthusiasts will conclude that the treatment in question is at least promising, if not recommendable, while real scientists will rightly state that the available data are too flimsy to demonstrate the effectiveness of the therapy; as it is wrong to recommend unproven treatments, they will not recommend the treatment for routine use.


Influenza kills thousands of people every year. Immunisation could prevent many of these deaths. Those at particularly high risk, e.g. young children, individuals aged 65 and older and people with severe diseases in their medical history, are therefore encouraged to get immunised. Nova Scotia health officials have just started their annual flu shot campaign. Now they are warning about some anti-flu vaccine literature being distributed by a chiropractor.

The leaflets from local chiropractic clinics suggest that flu shots increase the risk of a child ending up in hospital and link Alzheimer’s disease to flu shots. When questioned about this, the chair of the Nova Scotia College of Chiropractors defended this misinformation and claimed the author of the pamphlet did his homework. “Chiropractic is really pro information. Look at the positive, look at the negative, look at both sides, get your information and make the appropriate decision that’s right for you,” he said.

However, Dr. Robert Strang, Nova Scotia’s chief public health officer, said the message is wrong and added that the pamphlet is not based on medicine and is confusing to the public. “It’s discouraging, but unfortunately there are a range of what I call alternative-medicine practitioners who espouse a whole bunch of views which aren’t evidence based,” he said.

The stance of many chiropractors against immunisations is well known and has long historical roots. Campbell and colleagues expressed this clearly: Although there is overwhelming evidence to show that vaccination is a highly effective method of controlling infectious diseases, a vocal element of the chiropractic profession maintains a strongly antivaccination bias… The basis seems to lie in early chiropractic philosophy, which, eschewing both the germ theory of infectious disease and vaccination, considered disease the result of spinal nerve dysfunction caused by misplaced (subluxated) vertebrae. Although rejected by medical science, this concept is still accepted by a minority of chiropractors. Although more progressive, evidence-based chiropractors have embraced the concept of vaccination, the rejection of it by conservative chiropractors continues to have a negative influence on both public acceptance of vaccination and acceptance of the chiropractic profession by orthodox medicine.

No doubt, there will be comments following this post claiming that many chiropractors have now learnt their lesson and have considerably revised their stance on vaccination. This may well be true. But far too many chiropractors still post hair-raising nonsense about vaccination. Take this guy, for instance, who concludes his article (just one example of many) on the subject with this revealing paragraph: Our original blood was good enough. What a thing to say about one of the most sublime substances in the universe. Our original professional philosophy was also good enough. What a thing to say about the most evolved healing concept since we crawled out of the ocean. Perhaps we can arrive at a position of profound gratitude if we could finally appreciate the identity, the oneness, the nobility of an uncontaminated unrestricted nervous system and an inviolate bloodstream. In such a place, is not the chiropractic position on vaccines self-evident, crystal clear, and as plain as the sun in the sky? 

As long as dangerous cranks are tolerated by the vast majority of chiropractors and their professional organisations to mislead the public, I have to agree with Dr Strang: “It’s discouraging, but unfortunately there are a range of what I call alternative-medicine practitioners who espouse a whole bunch of views which aren’t evidence based.”

Many experts have warned us that, when we opt for dietary supplements, we might get more than we bargained for. A recent article reminded us that the increased availability and use of botanical dietary supplements and herbal remedies among consumers has been accompanied by an increased frequency of adulteration of these products with synthetic pharmaceuticals. Unscrupulous producers may add drugs and analogues of various classes, such as phosphodiesterase type 5 (PDE-5) inhibitors, weight loss, hypoglycemic, antihypertensive and anti-inflammatory agents, or anabolic steroids, to develop or intensify biological effects of dietary supplements or herbal remedies. The presence of such adulterated products in the marketplace is a worldwide problem and their consumption poses health risks to consumers.

Other authors recently warned that these products are often ineffective, adulterated, mislabeled, or have unclear dosing recommendations, and consumers have suffered injury and death as a consequence. When Congress passed the Dietary Supplement Health and Education Act, it stripped the Food and Drug Administration of its premarket authority, rendering regulatory controls too weak to adequately protect consumers. State government intervention is thus warranted. This article reviews studies reporting on Americans’ use of dietary supplements marketed for weight loss or muscle building, notes the particular dangers these products pose to the youth, and suggests that states can build on their historical enactment of regulatory controls for products with potential health consequences to protect the public and especially young people from unsafe and mislabeled dietary supplements.

A new study has shown that these problems are not just theoretical but are real and common.

Twenty-four products suspected of containing anabolic steroids and sold in fitness equipment shops in the UK were analyzed for their qualitative and semi-quantitative content using full scan gas chromatography-mass spectrometry (GC-MS), accurate mass liquid chromatography-mass spectrometry (LC-MS), high pressure liquid chromatography with diode array detection (HPLC-DAD), UV-Vis, and nuclear magnetic resonance (NMR) spectroscopy. In addition, X-ray crystallography enabled the identification of one of the compounds, where reference standard was not available.

Of the 24 products tested, 23 contained steroids including known anabolic agents; 16 of these contained steroids that were different to those indicated on the packaging and one product contained no steroid at all. Overall, 13 different steroids were identified; 12 of these are controlled in the UK under the Misuse of Drugs Act 1971. Several of the products contained steroids that may be considered to have considerable pharmacological activity, based on their chemical structures and the amounts present.

The authors concluded that such adulteration could unwittingly expose users to a significant risk to their health, which is of particular concern for naïve users.

The Internet offers thousands of supplements for sale; specifically for bodybuilders there are hundreds of supplements all claiming things that are untrue or untested. The lax regulations that exist in this area seem to be often ignored completely. I think it is important to inform customers that most supplements are a waste of money and some even a waste of health.

As a pharmacy professional, you must:

1. Make patients your first concern
2. Use your professional judgement in the interests of patients and the public
3. Show respect for others
4. Encourage patients and the public to participate in decisions about their care
5. Develop your professional knowledge and competence
6. Be honest and trustworthy
7. Take responsibility for your working practices.

Even though these 7 main principles were laid down by the UK General Pharmaceutical Council, they are pretty much universal and apply to pharmacists the world over.

On this blog, I have repeatedly criticised community pharmacists (here I am only discussing this branch of pharmacists) for selling remedies which are not just of debatable efficacy but which fly in the face of science and have been all but disproven. Recently, I came across this website of a working group of the Austrian Society of Pharmacists. It is in German, so I will translate a few sections for you.

They say that it is their aim to find “explanatory models for the mechanisms of action of homeopathy”. This is a strange aim, in my view, not least because there is no proven efficacy; why then search for a mechanism?

Things go from bad to worse when we consider the ‘Notfallapotheke’, the emergency kit which they recommend to consumers who might find themselves in desperate need for emergency care. It includes the following remedies, doses and indications:

Aconitum C 30 2 x 5 Glob, first remedy in cases of fever
Allium cepa C 12 3 x 5 Glob, hayfever or cold
Anamirta cocculusLM 12 : 2 x 5, travel sickness
Apis mellifica C 200 2 x 5 Glob, insect bites
Arnica C 200 1 x 5 Glob, injuries
Acidum arsenicosum C 12 3 – 5 x 5, food poisoning
Atropa belladonna C 30 2 x 5 Glob, high fever
Cephaelis ipecacuahna C 12 2 x 5 Glob, nausea and vomiting
Coffea arabica C 12 2 x 5 Glob, insomnia and restlessness
Euphrasia officinalis C 12 3 x 5 Glob, eye problems
Ferrum phosphoricum C 12 2 x 5 Glob, nose bleed
Lachesis muta C 30 1 x 5 Glob, infected wounds
Lytta vesicatoria C 200 1 – 2 x 5, burns,
Matricaria chamomilla C 30 1 x 3 Glob, toothache
Mercurius LM 12 2 x 5 Glob ear ache, weakness
Pulsatilla LM 12 2 x 5 Glob, ear ache, indigestion
Solanum dulcamara C12 3 x 5 Glob, cystitis
Strychnos nux vomica LM 12 2 x 5 Glob, hangover
Rhus toxicodendron C 200 2 x 5 Glob, rheumatic pain
Veratrum album C12, 3-5 x 3, watery diarrhoea, nausea, vomiting, circulatory problems, collapse.

I can well imagine that, after reading this, some of my readers are in need of some Veratrum album because of near collapse with laughter (or fury?).

We all know that most pharmacists sell such useless remedies; and we might pity them for such behaviour, as they claim they have no choice. But if pharmacists’ professional organisations put themselves so very clearly behind quackery thereby violating all ethical rules in the book, one is truly speechless.

Do I hear someone mutter “what has Austria to do with us?”?

Not a lot, perhaps – but have a look at the range of similar ‘homeopathic emergency kits’ sold outside Austria. Or be stunned by the plethora of homeopathic pharmacies across the globe here and UK-wide here. Or consider the fact that most non-homeopathic pharmacies in the world sell homeopathic remedies. Or let me remind you that a snapshot investigation into UK pharmacies revealed that 13 out of 20 pharmacisits failed to explain that there’s no clinical evidence that homeopathy works. Or be once again reminded that it is “the ethical role of the pharmacist is to give accurate, impartial information regarding the homeopathic therapy, the current scientific proof on their therapeutic effects, including the placebo effect.”

And what is the current scientific proof?

The most reliable verdict that I am aware of comes from the Australian ‘NATIONAL HEALTH AND MEDICAL RESEARCH COUNCIL’ (NHMRC) who have assessed the effectiveness of homeopathy. The evaluation concluded that “the evidence from research in humans does not show that homeopathy is effective for treating the range of health conditions considered.”

I rest my case.

Many proponents of alternative medicine seem somewhat suspicious of research; they have obviously understood that it might not produce the positive result they had hoped for; after all, good research tests hypotheses and does not necessarily confirm beliefs. At the same time, they are often tempted to conduct research: this is perceived as being good for the image and, provided the findings are positive, also good for business.

Therefore they seem to be tirelessly looking for a study design that cannot ‘fail’, i.e. one that avoids the risk of negative results but looks respectable enough to be accepted by ‘the establishment’. For these enthusiasts, I have good news: here is the study design that cannot fail.

It is perhaps best outlined as a concrete example; for reasons that will become clear very shortly, I have chosen reflexology as a treatment of diabetic neuropathy, but you can, of course, replace both the treatment and the condition as it suits your needs. Here is the outline:

  • recruit a group of patients suffering from diabetic neuropathy – say 58, that will do nicely,
  • randomly allocate them to two groups,
  • the experimental group receives regular treatments by a motivated reflexologist,
  • the controls get no such therapy,
  • both groups also receive conventional treatments for their neuropathy,
  • the follow-up is 6 months,
  • the following outcome measures are used: pain reduction, glycemic control, nerve conductivity, and thermal and vibration sensitivities,
  • the results show that the reflexology group experience more improvements in all outcome measures than those of control subjects,
  • your conclusion: This study exhibited the efficient utility of reflexology therapy integrated with conventional medicines in managing diabetic neuropathy.

Mission accomplished!

This method is fool-proof, trust me, I have seen it often enough being tested, and never has it generated disappointment. It cannot fail because it follows the notorious A+B versus B design (I know, I have mentioned this several times before on this blog, but it is really important, I think): both patient groups receive the essential mainstream treatment, and the experimental group receives a useless but pleasant alternative treatment in addition. The alternative treatment involves touch, time, compassion, empathy, expectations, etc. All of these elements will inevitably have positive effects, and they can even be used to increase the patients’ compliance with the conventional treatments that is being applied in parallel. Thus all outcome measures will be better in the experimental compared to the control group.

The overall effect is pure magic: even an utterly ineffective treatment will appear as being effective – the perfect method for producing false-positive results.

And now we hopefully all understand why this study design is so very popular in alternative medicine. It looks solid – after all, it’s an RCT!!! – and it thus convinces even mildly critical experts of the notion that the useless treatment is something worth while. Consequently the useless treatment will become accepted as ‘evidence-based’, will be used more widely and perhaps even reimbursed from the public purse. Business will be thriving!

And why did I employ reflexology for diabetic neuropathy? Is that example not a far-fetched? Not a bit! I used it because it describes precisely a study that has just been published. Of course, I could also have taken the chiropractic trial from my last post, or dozens of other studies following the A+B versus B design – it is so brilliantly suited for misleading us all.
