Some doctors use homeopathy, and for proponents of homeopathy this has always been a strong argument for its effectiveness. They claim that someone who has studied medicine would not employ a therapy that does not work. I have long felt that this view is erroneous.

This article goes some way in finding out who is right. It was aimed at describing the use of homeopathy by physicians working in outpatient care, factors associated with prescribing homeopathy, and the therapeutic intentions and attitudes involved.

All physicians working in outpatient care in the Swiss Canton of Zurich in the year 2015 (n = 4072) were approached. Outcomes of the survey were:

  • association of prescribing homeopathy with medical specialties;
  • intentions behind prescriptions;
  • level of agreement with specific attitudes;
  • views towards homeopathy including explanatory models,
  • rating of homeopathy’s evidence base,
  • the endorsement of indications,
  • reimbursement of homeopathic treatment by statutory health insurance providers.

The participation rate was 38%, mean age 54 years, 61% male, and 40% specialised in general internal medicine. Homeopathy was prescribed at least once a year by 23% of the respondents. Medical specialisations associated with prescribing homeopathy were: no medical specialisation (OR 3.9; 95% CI 1.7-9.0), specialisation in paediatrics (OR 3.8 95% CI 1.8-8.0) and gynaecology/obstetrics (OR 3.1 95% CI 1.5-6.7).

Among prescribers, only 50% clearly intended to induce specific homeopathic effects, only 27% strongly adhered to homeopathic prescription doctrines, and only 23% thought there was scientific evidence to prove homeopathy’s effectiveness. Seeing homeopathy as a way to induce placebo effects had the strongest endorsement among prescribers and non-prescribers of homeopathy (63% and 74% endorsement respectively). Reimbursement of homeopathic remedies by statutory health insurance was rejected by 61% of all respondents

The authors concluded that medical specialties use homeopathy with significantly varying frequency and only half of the prescribers clearly intend to achieve specific effects. Moreover, the majority of prescribers acknowledge that effectiveness is unproven and give little importance to traditional principles behind homeopathy. Medical specialties and associated patient demands but also physicians’ openness towards placebo interventions may play a role in homeopathy prescriptions. Education should therefore address not only the evidence base of homeopathy, but also ethical dilemmas with placebo interventions.

These data suggest than many doctors use homeopathy as a placebo. And this is what I had always suspected. Certainly I did often employ it in this way when I still worked as a clinician. The logic of doing so is quite simple: there are many patients where, after running all necessary tests, you conclude that there is nothing wrong with them. You try your best to get the message across but it is not accepted by the patient who clearly wants to have a prescription for something. In the end, due to time pressure etc., you give up and prescribe a homeopathic remedy hoping that the placebo effect, regression towards the mean and the natural history of the condition will do the trick.

And often they do!

I do know that this is hardly good medicine and arguably even not entirely ethical, but it is the reality. If I found myself in the same situation again, I am not sure that I would not do something similar.

This randomized controlled trial was aimed to investigate the effect of aromatherapy massage on anxiety, depression, and physiologic parameters in older patients with acute coronary syndrome. It was conducted on 90 older women with acute coronary syndrome. The participants were randomly assigned into the intervention and control groups. The intervention group received reflexology with lavender essential oil plus routine care and the control group only received routine care. Physiologic parameters, the levels of anxiety and depression in the hospital were evaluated using a checklist and the Hospital’s Anxiety and Depression Scale, respectively, before and immediately after the intervention.

Significant differences in the levels of anxiety and depression were reported between the groups after the intervention. The analysis of physiological parameters revealed a statistically significant reduction in systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate. However, no significant difference was observed in the respiratory rate.

The authors concluded that aromatherapy massage can be considered by clinical nurses an efficient therapy for alleviating psychological and physiological responses among older women suffering from acute coronary syndrome.

WRONG!

This trial does not show remotely what the authors think. It demonstrates that A+B is always more than B. We have discussed this phenomenon so often that I hesitate to mention it again. Any study with the ‘A+B versus B’ design can only produce a positive result. The danger that this result is false-positive is so high that it is best to forget about such investigations altogether.

Ethics committees should not accept such protocols.

Researchers should stop running such studies.

Reviewers should not pass them for publication.

Editors should not publish such trials.

THEY MISLEAD ALL OF US AND GIVE CLINICAL RESEARCH A BAD NAME.

It was the very first sentence of the Boiron US website on Oscillococcinum (we have discussed this amazing product before) that caught my attention: “Homeopathy is a therapeutic method that uses diluted substances to relieve symptoms.” I think this is demonstrably wrong.

  • Homeopathy is a therapeutic method that uses mostly the complete absence of an ingredient, and not ‘diluted substances’; specifically, Oscillococcinum is a  C 200 potency ( 1: 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000) which means the likelihood of any substance being present is zero.
  • Homeopathy is, according to Hahnemann, not ‘to relieve symptoms’ but to tackle the root cause of the condition. Hahnemann meant it to be a causal and not a symptomatic treatment (the truth is that it neither relieves symptoms or the root cause of anything).

And then the website continued to puzzle me by stating this: “The active ingredients in homeopathic medicines include diluted plants, animals or minerals that relieve the same symptoms they cause at full strength (i.e., a micro dose of coffee bean helps to relieve nervousness).” This is wrong too, I think:

  • there is no active ingredient in homeopathic medicines,
  • many of the mother tinctures used in homeopathy cause no symptoms whatsoever,
  • a zero dose is not a micro dose,
  • homeopathic coffee does not relieve nervousness better than a placebo.

Now my interest was aroused and I decided to read on. This is what I found under the heading of ‘Frequently Asked Questions’:

Are there clinical studies on Oscillococcinum?

Yes. Two studies, published in peer-reviewed journals, show that Oscillococcinum helps to reduce the severity and shorten the duration of flu-like symptoms.1-2 The most recent study showed that 63 percent of the patients who took Oscillo at the onset of flu-like symptoms showed “clear improvement” or “complete resolution” of their symptoms after 48 hours, vs. 48% with a placebo.2

Now, this is strange!

Why would they cite just two studies when there are several more? Surely they don’t want to be seen to be cherry picking!?!? The current Cochrane review by Mathie RT, Frye J, Fisher P., for instance, included 6 trials!

And what did this review show?

The authors concluded that “There is insufficient good evidence to enable robust conclusions to be made about Oscillococcinum® in the prevention or treatment of influenza and influenza-like illness. Our findings do not rule out the possibility that Oscillococcinum® could have a clinically useful treatment effect but, given the low quality of the eligible studies, the evidence is not compelling. There was no evidence of clinically important harms due to Oscillococcinum®.”

Even though the authors of this Cochrane review are amongst the most ardent homeopathy-promoters on the planet (if not they would not have included this odd 2nd sentence in the above quote), this conclusion does not seem to please Boiron (Christian Boiron seems to have not much time for critical thinking; in a recent, short interview he opined that “Il y a un Ku Klux Klan contre l’homéopathie” THERE IS A KU KLUX KLAN AGAINST HOMEOPATHY).

After studying all this, I ask myself whether Boiron is telling the truth.

What do you think?

 

 

 

On their website, the ASA yesterday published a statement about chiropractic. It outlines which claims UK chiropractors are allowed to make and which are likely to get them into conflict with the ASA. Here are a few excerpts (my comments are added in bold):

Chiropractic is a healthcare profession that focuses on diagnosis, treatment and prevention of mechanical disorders of the musculoskeletal system, with special emphasis on the spine. It emphasises manual therapy including spinal manipulation and other joint and soft-tissue manipulation, and includes exercises, and health and lifestyle counselling…

Why not say as it is: more than 90% of patients consulting a chiropractor will receive spinal manipulations. Therefore the best way to define chiropractic is by its hallmark intervention. Using vague language like ‘manual therapy… exercises, and health and lifestyle counselling’ creates big problems and opens the door to all sorts of therapeutic claims (see below).

In 2017 the ASA carried out an evidence review on the use of multi-modal approaches used in Chiropractic in treating sciatica, whiplash and sports injuries as well as the treatment of babies, children and pregnant women as specific patient groups. The subsequent ASA Guidance explains in more detail the types of claims (including phraseology) that are likely to be acceptable for chiropractors to make in their advertising and those which are not.   We recommend chiropractors consider this CAP advice and the ASA Guidance together when making treatment claims in advertising.

Based on all evidence submitted and reviewed to date, the ASA and CAP accept that chiropractors may claim to treat the following conditions:

  • Ankle sprain (short term management)
  • Cramp
  • Elbow pain and tennis elbow (lateral epicondylitis) arising from associated musculoskeletal conditions of the back and neck, but not isolated occurrences
  • Headache arising from the neck (cervicogenic)
  • Inability to relax
  • Joint pains
  • Joint pains including hip and knee pain from osteoarthritis as an adjunct to core OA treatments and exercise
  • General, acute & chronic backache, back pain (not arising from injury or accident)
  • Generalised aches and pains
  • Lumbago
  • Mechanical neck pain (as opposed to neck pain following injury i.e. whiplash)
  • Migraine prevention
  • Minor sports injuries and tensions
  • Muscle spasms
  • Plantar fasciitis (short term management)
  • Rotator cuff injuries, disease or disorders
  • Sciatica
  • Shoulder complaints (dysfunction, disorders and pain)
  • Soft tissue disorders of the shoulder

I am puzzled by this list; for most indications, there is no good evidence at all – unless, of course, we consider chiropractic to consist of ‘manual therapy… exercises, and health and lifestyle counselling’ (see above). But, in this case, the list is still very odd because it would then need to include practically all conditions that can affect humans. Or does anyone know of many diseases that cannot benefit from ‘health and lifestyle counselling’?

…As regulated health professionals, chiropractors may refer to treating specific population groups such as pregnant women, children and babies. However, at present there is a limited or negative evidence base for the effectiveness of chiropractic (here the ASA use the term ‘chiropractic’ not as defined above but as a type of therapy which I think is correct but most chiros object to) in treating conditions specific to those groups, such as colic or morning sickness.

Consequently, references to treatment for symptoms and conditions that are likely to be understood to be specific to babies, children or pregnant women are unlikely to be acceptable unless the marketer holds a robust body of evidence…

And why should this be? Is ‘health and lifestyle counselling’ not effective for these conditions? Clearly it is! So this restriction is illogical.

I think, the ASA got themselves into a major muddle here. The only way to sort it out is to define chiropractic by its main therapy, spinal manipulation, and judge it by the proven risks and benefits of this intervention. (A surgeon will also often give ‘health and lifestyle counselling’, but this does not mean that surgery is indicated for migraine, common cold, asthma etc.)

And if we follow this approach, we instantly see that the ASA list of allowed claims makes no sense whatsoever!

I have this minute learnt the following from this website:

RCVS POSITION ON COMPLEMENTARY AND ALTERNATIVE MEDICINES

“We have recently been asked questions about complementary and alternative medicines and treatments in general and homeopathy in particular.

“We would like to highlight our commitment to promoting the advancement of veterinary medicine upon sound scientific principles and to re-iterate the fundamental obligation upon our members as practitioners within a science-based profession which is to make animal welfare their first consideration. “In fulfilling this obligation, we expect that treatments offered by veterinary surgeons are underpinned by a recognised evidence base or sound scientific principles. Veterinary surgeons should not make unproven claims about any treatments, including prophylactic treatments.

“Homeopathy exists without a recognised body of evidence for its use. Furthermore, it is not based on sound scientific principles. In order to protect animal welfare, we regard such treatments as being complementary rather than alternative to treatments for which there is a recognised evidence base or which are based in sound scientific principles. It is vital to protect the welfare of animals committed to the care of the veterinary profession and the public’s confidence in the profession that any treatments not underpinned by a recognised evidence base or sound scientific principles do not delay or replace those that do.”

END OF QUOTE

I think this is excellent and thank everybody who contributed to achieving this victory of reason over quackery.

During Voltaire’s time, this famous quote was largely correct. But today, things are very different, and I often think this ‘bon mot’ ought to be re-phrased into ‘The art of alternative medicine consists in amusing the patient, while medics cure the disease’.

To illustrate this point, I shall schematically outline the story of a patient seeking care from a range of clinicians. The story is invented but nevertheless based on many real experiences of a similar nature.

Tom is in his mid 50s, happily married, mildly over-weight and under plenty of stress. In addition to holding a demanding job, he has recently moved home and, as a consequence of lots of heavy lifting, his whole body aches. He had previous episodes of back trouble and re-starts the exercises a physio once taught him. A few days later, the back-pain has improved and most other pains have subsided as well. Yet a dull and nagging pain around his left shoulder and arm persists.

He is tempted to see his GP, but his wife is fiercely alternative. She was also the one who dissuaded  Tom from taking Statins for his high cholesterol and put him on Garlic pills instead. Now she gives Tom a bottle of her Rescue Remedy, but after a week of taking it Tom’s condition is unchanged. His wife therefore persuades him to consult alternative practitioners for his ‘shoulder problem’. Thus he sees a succession of her favourite clinicians.

THE CHIROPRACTOR examines Tom’s spine and diagnoses subluxations to be the root cause of his problem. Tom thus receives a series of spinal manipulations and feels a little improved each time. But he is disappointed that the pain in the left shoulder and arm returns. His wife therefore makes another appointment for him.

THE ENERGY HEALER diagnoses a problem with Tom’s vital energy as the root cause of his persistent pain. Tom thus receives a series of healing sessions and feels a little improved each time. But he is disappointed that the pain in the left shoulder and arm returns. His wife therefore makes another appointment for him.

THE REFLEXOLOGIST examines Tom’s foot and diagnoses knots on the sole of his foot to cause energy blockages which are the root cause of his problem. Tom thus receives a series of most agreeable foot massages and feels a little improved each time. But he is disappointed that the pain in the left shoulder and arm returns. His wife therefore makes another appointment for him.

THE ACUPUNCTURIST examines Tom’s pulse and tongue and diagnoses a chi deficiency to be the root cause of his problem. Tom thus receives a series of acupuncture treatments and feels a little improved each time. But he is disappointed that the pain in the left shoulder and arm returns. His wife therefore makes another appointment for him.

THE NATUROPATH examines Tom and diagnoses some form of auto-intoxication as the root cause of his problem. Tom thus receives a full program of detox and feels a little improved each time. But he is disappointed that the pain in the left shoulder and arm returns. His wife therefore makes another appointment for him.

THE HOMEOPATH takes a long and detailed history and diagnoses a problem with Tom’s vital force to be the root cause of his pain. Tom thus receives a homeopathic remedy tailor-made for his needs and feels a little improved after taking it for a few days. But he is disappointed that the pain in the left shoulder and arm returns. His wife therefore tries to make another appointment for him.

But this time, Tom had enough. His pain has not really improved and he is increasingly feeling unwell.

At the risk of a marital dispute, he consults his GP. The doctor looks up Tom’s history, asks a few questions, conducts a brief physical examination, and arranges for Tom to see a specialist. A cardiologist diagnoses Tom to suffer from coronary heart disease due to a stenosis in one of his coronary arteries. She explains that Tom’s dull pain in the left shoulder and arm is a rather typical symptom of this condition.

Tom has to have a stent put into the affected coronary artery, receives several medications to lower his cholesterol and blood pressure, and is told to take up regular exercise, lose weight and make several other changes to his stressful life-style. Tom’s wife is told in no uncertain terms to stop dissuading her husband from taking his prescribed medicines, and the couple are both sent to see a dietician who offers advice and recommends a course on healthy cooking. Nobody leaves any doubt that not following this complex (holistic!) package of treatments and advice would be a serious risk to Tom’s life.

It has taken a while, but finally Tom is pain-free. More importantly, his prognosis has dramatically improved. The team who now look after him have no doubt that a major heart attack had been imminent, and Tom could easily have died had he continued to listen to the advice of multiple non-medically trained clinicians.

The root cause of his condition was misdiagnosed by all of them. In fact, the root cause was the atherosclerotic degeneration in his arteries. This may not be fully reversible, but even if the atherosclerotic process cannot be halted completely, it can be significantly slowed down such that he can live a full life.

My advice based on this invented and many real stories of a very similar nature is this:

  • alternative practitioners are often good at pampering their patients;
  • this may contribute to some perceived clinical improvements;
  • in turn, this perceived benefit can motivate patients to continue their treatment despite residual symptoms;
  • alternative practitioner’s claims about ‘root causes’ and holistic care are usually pure nonsense;
  • their pampering may be agreeable, but it can undoubtedly cost lives.

George Vithoulkas * (GV) is one of today’s most influential lay-homeopaths, a real ‘super guru’. He has many bizarre ideas; one of the most peculiar one was recently outlined in his article entitled ‘An innovative proposal for scientific alternative medical journals’. Here are a few excerpts from it:

…the only evidence that homeopathy can present to the scientific world at this moment are these thousands of cured cases. It is a waste of time, money, and energy to attempt to demonstrate the effectiveness of homeopathy through double blind trials.

… the international “scientific” community, which has neither direct perception nor personal experience of the beneficial effects of homeopathy, is forced to repeat the same old mantra: “Where is the evidence? Show us the evidence!” … the successes of homeopathy have remained hidden in the offices of hardworking homeopaths – and thus go largely ignored by the world’s medical authorities, governments, and the whole international scientific community…

… simple questions that are usually asked by the “gnorant”, for example, “Can homeopathy cure cancer, multiple sclerosis, ulcerative colitis, etc.?” are invalid and cannot elicit a direct answer because the reality is that many such cases can be ameliorated significantly, and a number can be cured…

A journal could invite a selected number of good prescribers from all over the world as a start to this project and let them contribute to their honest experience and results, as well as their failures. The possibilities and limitations would soon be revealed…

I admit that an argument against accepting cases is that it is possible that false or unreliable information could be provided. This risk could be minimized by preselecting a well-known group of good prescribers, who could be asked to submit their cases, at least in the first phase of such a radical change in the policy of the journals…

This way, instead of rejecting important homeopathic case studies, in the name of a dry intellectualism and conservatism, homeopathy journals (including alternative and complementary journals) could become lively and interesting: initiating debates and discussions on real issues of therapeutics in medicine…

Our own “Evidence Based Medicine” lies in the multitude of chronic cases treated with homeopathy that we can present to the world and on the better quality of life that such cures offer.

END OF QUOTES

So, GV wants homeopathy to thrive by means of publishing lots of case reports of patients who benefitted from homeopathy. And he believes that this suggestion is ‘innovative’? It is not! Case reports were all the rage 150 years ago before medicine started to become a little more scientific. And today, there are several journals specialising in the publication of case-reports, hundreds of journals that like accepting them, as well as dozens of websites that do little else but publishing case reports of homeopathy.

But case reports essentially are anecdotes. Medicine finally managed to progress from its dark ages when we realised how unreliable case reports truly are. To state it yet again (especially for GV who seems to be a bit slow on the uptake): THE PLURAL OF ANECDOTE IS ANECDOTES, NOT EVIDENCE!

In the above article, GV claims that ‘it is a waste of time, money, and energy to attempt to demonstrate the effectiveness of homeopathy through double blind trials.’ That is most puzzling because, only a few years ago, he did publish this:

Alternative therapies in general, and homeopathy in particular, lack clear scientific evaluation of efficacy. Controlled clinical trials are urgently needed, especially for conditions that are not helped by conventional methods. The objective of this work was to assess the efficacy of homeopathic treatment in relieving symptoms associated with premenstrual syndrome (PMS). It was a randomised controlled double-blind clinical trial. Two months baseline assessment with post-intervention follow-up for 3 months was conducted at Hadassah Hospital outpatient gynaecology clinic in Jerusalem in Israel 1992-1994. The subjects were 20 women, aged 20-48, suffering from PMS. Homeopathic intervention was chosen individually for each patient, according to a model of symptom clusters. Recruited volunteers with PMS were treated randomly with one oral dose of a homeopathic medication or placebo. The main outcome measure was scores of a daily menstrual distress questionnaire (MDQ) before and after treatment. Psychological tests for suggestibility were used to examine the possible effects of suggestion. Mean MDQ scores fell from 0.44 to 0.13 (P<0.05) with active treatment, and from 0.38 to 0.34 with placebo (NS). (Between group P=0.057). Improvement >30% was observed in 90% of patients receiving active treatment and 37.5% receiving placebo (P=0.048). Homeopathic treatment was found to be effective in alleviating the symptoms of PMS in comparison to placebo. The use of symptom clusters in this trial may offer a novel approach that will facilitate clinical trials in homeopathy. Further research is in progress.

I find this intriguing, particularly because the ‘further research’ mentioned prominently in the conclusions never did surface! Perhaps its results turned out to be unfavourable to homeopathy? Perhaps this is why GV dislikes RCTs these days? Perhaps this is why he prefers case reports such as this one which he recently published:

START OF QUOTE

An 81-year-old female patient was admitted in July 2015 to the Cardiovascular Surgery Department of a hospital in Bucharest for an aortic valve replacement surgery.

The patient had a history of mild hypertension, insulin-dependent type 2 diabetes, coronary artery disease, congestive heart failure NYHA 2, severe aortic stenosis, moderate mitral regurgitation, mild pulmonary hypertension, bilateral carotid atheromatosis with a 50% stenosis of the left internal carotid artery, complete right mastectomy for breast cancer (at that moment in remission).

After a preoperative evaluation and preparation, the surgery was completed with the replacement of the aortic valve with a bioprosthesis (Medtronic Hancock II Ultra no. 23) and myocardial revascularization by using a double aortic-coronary bypass.

The post-operatory evolution was a good one in terms of the heart disease. However, the patient did not regain consciousness after the anaesthesia, maintaining a deep comatose state (GCS 7 points – E1V2M4).

A brain CT was performed the third day postoperatively, showing no recent ischemic or haemorrhagic cerebral lesions, moderate diffuse cerebral atrophy and carotid atheromatosis.

After the surgery, the patient was admitted to the Intensive Care Unit and was treated by using a multidisciplinary approach. The patient was treated with inotropic, antiarrhythmic, and diuretic drugs, insulin and antidiabetic drugs were used in order to keep the blood sugar levels under control. The patient was kept hydrated and the electrolytes balanced by using an i.v. line, prophylaxis for deep vein thrombosis, and pulmonary thromboembolism was performed by using low molecular weight heparin. Prophylaxis for bedsores was also performed by using a pressure relieve air mattress.

The patient went into acute respiratory distress, needing mechanical ventilation in order to maintain oxygenation.

Despite these complex and correctly performed therapeutic efforts, the patient did not regain consciousness and was still in a deep coma in the fourteenth day post-operatory (GCS 7 points – E1V2M4), without having a confirmed medical explanation.

At that point, the patient’s family requested a consult from a homeopathic specialist.

The homeopathic examination, which was performed in the fourteenth day postoperatively, revealed the following: old, comatose, tranquil patient, with pale and cold skin, with the need to uncover herself (the few movements that she made with her hands were to remove her blanket and clothes, as if she wanted more air – “thirst for air”), abdominal distension, and bloating.

The thorough evaluation of the patient and the analysis of her symptoms led us to the remedy most appropriate for this critical situation – Carbo Vegetabilis.

Homeopathic treatment was initiated the same day, by using Carbo Vegetabilis 200CH 7 granules twice a day, administered diluted in 20ml of water by using a nasogastric tube.

The patient’s evolution was spectacular. The next day after the initiation of the treatment (fifteenth day postoperatively) the patient was in a superficial coma (GCS 11 points – E2V4M5), and the following day she regained consciousness. Carbo Vegetabilis was administered in the same dose for a total of five days (including the nineteenth day postoperatively).

After these five days, the case was reassessed from a homeopathically point of view and the second evaluation revealed the following: severely dyspnoeic patient (even talking caused exhaustion) with pale skin, severe fatigue aggravated by the slightest movements, a weakness sensation located in the chest area, extreme lack of energy, the wish “to be left alone”.

Considering the state of general exhaustion the patient was in at that moment and her lack of energy, the homeopathic treatment was changed to a new remedy: Stanum metallicum 30CH 7 granules administered sublingually twice a day for a week.

After the administration of the second remedy, the patient’s general condition improved dramatically: she started eating, she was able to get up in a sitting position with only little help, her fatigue diminished significantly.

The patient was then transferred to a recovery clinic in Cluj-Napoca in order to continue the cardiovascular recovery treatment. During her three-week admission in the clinic, she followed an individualized cardiovascular recovery program, which led to her ability to walk short distances with minimal support and has was released from the hospital in September 2015.

The following weeks after release, the patient recovered almost entirely, both physically and mentally. She was able to retake her place in her family and in society in general.

END OF QUOTE

One has to be a homeopath (one who is ignorant of the ‘post hoc propter hoc fallacy’) to believe in a causal link between the intake of the homeopathic remedy and the recovery of this patient. Thankfully, comatose patients do re-gain consciousness all the time! Even without homeopathy! But GV seems to not know that. In the discussion of this paper, he even states this: “ even after a well-conducted therapy, this condition leads to the death of the patient.” Is it ethical to publish such falsehoods, I wonder?

As far as the case report goes, the homeopathic remedy might even have delayed the process – perhaps the patient would have re-gained consciousness quicker and more completely without it! My hypothesis (homeopathy cased harm) is exactly as strong and silly as the one (homeopathy cased benefit) of GV. Anecdotes will never be able to answer the question as to who is correct.

One has to be a homeopath (and a daft one at that) to believe that this sort of evidence will lead to the acceptance of homeopathy by the scientific community. No journal will take GV seriously. No editor can be that stupid!

Oooops! Hold on, I might be wrong here.

Dr Peter Fisher, editor of the journal ‘Homeopathy’ just published an editorial ( Fisher P, Homeopathy and intellectual honesty, Homeopathy (2017), see also my previous post) stating that, in future, ‘we will increase publication of well-documented case-reports’.

Did I just claim that no editor can be that stupid?

 

 

 

  • I should declare a conflict of interest: when he got his ‘Right Livelihood Award’, GV sent me (and other prominent homeopathy-researchers) some of the prize money (I think it was around £ 1000) to support my research in homeopathy. I used it for exactly that purpose.

 

Dr Peter Fisher (I have mentioned him several times before, see for instance here, here and here) claimed in his recent editorial (Fisher P, Homeopathy and intellectual honesty, Homeopathy (2017) – not yet available on Medline) that 43 systematic reviews of homeopathy have so far been published, and stated that “of these 21 were clearly or tentatively positive and 9 inconclusive”. In my book, this would mean that the majority of systematic reviews fail to be clearly positive. But Fisher seems to view this mini-statistic as a proof of homeopathy’s efficacy.

As evidence for his statement, Fisher cites this article from his own journal (‘Homeopathy’). However, the paper actually says this: “A total of 36 condition-specific systematic reviews have been identified in the peer-reviewed literature: 16 of them reported positive, or tentatively positive, conclusions about homeopathy’s clinical effectiveness; the other 20 were negative or non-conclusive.”

Odd?

Confused by this contradiction, I try to dig deeper. Medline provides currently 66 hits when searching systematic reviews of homeopathy. But this figure includes papers that are not really systematic reviews and excludes some relevant articles that are not Medline-listed.

The NHMRC report which Fisher also cites (see below) considered 57 systematic reviews of homeopathy. In his editorial, Fisher stated that the NHMRC report “seems to have missed some systematic reviews of homeopathy”. This can only mean that Fisher knows of more than 57 reviews. Why then does he claim that there are just 43?

Odd?

Yes, but Fisher’s editorial seems odd in several other ways as well.

  • He accuses the NHMRC-authors of ‘malpractice’.
  • He finds ‘shocking evidence of bias’.
  • He alleges that the EASAC-report ‘cherry-picks evidence’.
  • He accuses the EASAC-authors of ‘abuse of authority’.

Definitely odd!

Why does Dr Peter Fisher go this far, why is he so very aggressive?

I know Peter quite well. He is usually a fairly calm and collected sort of person who is not prone to irrational outbursts. This behaviour is therefore out of character.

So, why?

The only explanation that I have for his strange behaviour is that he feels cornered, has run out of rational arguments, and senses that homeopathy is now on its last leg.

What do you think?

The German Heilpraktiker (a phenomenon vaguely equivalent to the ‘naturopath’ in English speaking countries) has become a fairly regular feature on this blog – see, for instance here, here, and here. The nationally influential German Medical Journal, a weekly publication of the German Medical Association, recently published an article about the education of this profession.

In it, we are told that the German Ministry of Health has drafted a 9-page document to unify the examination of the Heilpraktiker throughout Germany. The German Medical Association, however, are critical about the planned reform. The draft document suggest that, in future, all Heilpraktiker should pass an exam consisting of 60 multiple choice questions, in addition to an oral examination in which 4 candidates are being interviewed simultaneously for one hour. The draft also stipulates that Heilpraktiker may only practice such that they present no danger for public health and only use methods they muster.

The German Medical Association feel that these reforms do not go far enough. They claim that the authors of the draft have ‘totally misunderstood the complexity of the medical context, particularly the amount of necessary knowledge necessary for risk-minimisation in clinical practice’. They furthermore feel that the document is ‘an effort that is in every respect insufficient for protecting the public or individuals from the practice of the Heilpraktiker’. They also state that it is unclear how the document might provide a means to test Heilpraktiker in respect of risk-minimisation. The Medical Association demands that ‘the practice of certain therapies by Heilpraktiker must be forbidden. Finally, they say that ‘the practice of invasive methods and the treatment of caner by Heilpraktiker must be urgently prohibited’.

The German Heilpraktiker has been a subject of much public debate recently, not least after the ‘Muenster Group’ suggested a comprehensive reform. (I reported about this at the time.)

For those who can read German, the original article from the German Medical Journal is copied below:

Das Bundesministerium für Gesundheit (BMG) will gemeinsam mit den Ländern die Heilpraktikerüberprüfung bundesweit vereinheitlichen und Patienten besser schützen. Dafür haben Bund und Länder einen neunseitigen Entwurf erarbeitet. Die Bundes­ärzte­kammer (BÄK) zeigt sich angesichts der Pläne besorgt und übt deutliche Kritik.

Der Entwurf sieht vor, dass zur Überprüfung der Kenntnisse von Heilpraktikern künftig eine Prüfung verpflichtend sein soll. Diese soll aus 60 Multiple-Choice-Fragen bestehen, von denen der Anwärter innerhalb von zwei Stunden 45 korrekt ankreuzen muss. Darüber hinaus ist ein mündlicher Prüfungsteil von einer Stunde vorgesehen – bei vier Prüflingen gleichzeitig.

Zusätzlich stellt der Entwurf klar, dass Heilpraktiker nur in dem Umfang Heilkunde ausüben dürfen, in dem von ihrer Tätigkeit keine Gefahr für die Gesundheit der Bevölkerung oder für Patientinnen und Patienten ausgeht. Sie müssten zudem „eventuelle Arztvorbehalte beachten und sich auf die Tätigkeiten beschränken, die sie sicher beherrschen“, heißt es in der Präambel des Bund-Länder-Entwurfes, der dem Deutschen Ärzteblatt vorliegt.

Der Bundes­ärzte­kammer geht der Text nicht weit genug. Die Autoren der Leitlinie für die Prüfung haben laut BÄK „die Komplexität des medizinischen Kontextes“ völlig verkannt, „insbesondere das Ausmaß des notwendigen medizinischen Wissens, das für eine gefahrenminimierte Ausübung der Heilkunde notwendig ist“, so die Kammer weiter. Die jetzt vorgelegten Leitlinien für die Überprüfung stelle „eine in jeder Hinsicht unzureichende Maßnahme zum Schutz der Bevölkerung oder gar einzelner Patienten vor möglichen Gesundheitsgefahren durch die Tätigkeit von Heilpraktikern dar.

Es sei nicht nachvollziehbar, „wie auf der Grundlage dieser Leitlinien eine Überprüfung von Heilpaktikeranwärtern unter dem Aspekt einer funktionierenden Gefahrenabwehr erfolgen soll“, so die Kammer weiter. Sie fordert, dass Heilpraktikern bestimmte Tätigkeiten verboten werden. „Konkret sieht die Bundes­ärzte­kammer insbesondere den Ausschluss aller invasiven Maßnahmen sowie der Behandlung von Krebserkrankungen als zwingend notwendig an“, heißt es in der Stellungnahme.

Der Bund-Länder-Entwurf ist Ergebnis einer Debatte darüber, was Heilpraktiker dürfen oder künftig nicht (mehr) dürfen sollten und wie die Regeln für den Gesundheitsberuf aussehen. Eine Expertengruppe, der „Münsteraner Kreis“, hatte unlängst Vorschläge für eine umfassende Reform erarbeitet. Das Thema war zuletzt in der Öffentlichkeit und auch der Ärzteschaft heftig diskutiert worden.

END OF QUOTE

So, how well should alt med practitioners be educated and trained?

The answer depends, I think, on what precisely they are allowed to do. Medical responsibility must always be matched to medical competence. If a massage therapist merely acts on the instructions of a doctor, she does not need to know the differential diagnosis of a headache, for instance.

If, however, practitioners independently diagnose diseases (and alt med practitioners often do exactly that!), they must have a knowledge-base similar to that of a GP. If they use potentially harmful treatments (and which therapy does not have the potential to do harm?), they must be aware of the evidence for or against these interventions, as well as the evidence for all other therapeutic options for the conditions in question. Again, this would mean having a knowledge close to GP-level. If there is a mismatch between responsibility and competence (as very often is the case), patients are exposed to avoidable risks.

It is clear from these considerations that an exam with 60 multiple-choice questions followed by an hour-long interview is woefully inadequate for testing whether a practitioner has sufficient medical competence to independently care for patients. It is also clear, I think, that practitioners who regularly diagnose and treat patients – usually without any supervision – ought to have an education that covers much of what doctors learn while in medical school. Finally, it is clear that even after an adequate education, practitioners need to gather experience and work under supervision for some time before they can responsibly practice independently.

In any case, uncritically teaching obsolete notions of vitalism, yin and yang, subluxation, detox, potentisation, millennia of experience etc. is certainly not good enough. Education has to be based on sound evidence; if not, it is not education but brain-washing. And the result would be that students do not become responsible healthcare professionals but irresponsible charlatans.

Of course, alt med practitioners will argue that these arguments are merely the expression of medics defending their lucrative patch. But even if this were true (which, in my view, it is not), it would not absolve them from the moral, ethical and legal duty to demonstrate that their educational standards are sufficiently rigorous to avoid harm to their patients.

In a nutshell: an education in nonsense must result in nonsense.

 

I have often cautioned about what I call the ‘survey mania’ in alternative medicine. Yet, once in a while, an informative survey gets published. Take this recent survey, for instance:

It was based on a design-based logistic regression analysis of the European Social Survey (ESS), Round 7. The researchers distinguished 4 modalities: manual therapies, alternative medicinal systems, traditional Asian medical systems and mind-body therapies.

In total, 25.9% of the general population had used at least one of these therapies during the last 12 months which was around one-third of the proportion of those who had visited a general practitioner (76.3%). Typically, only one treatment had been used, and it was used more often as complementary rather than alternative treatment. The usage varied greatly by country (see Table 1 below). Compared to those in good health, the use of CAM was two to fourfold greater among those with health problems. The health profiles of users of different CAM modalities varied. For example, back or neck pain was associated with all types of CAM, whereas depression was associated only with the use of mind-body therapies. Individuals with difficult to diagnose health conditions were more inclined to utilize CAM, and CAM use was more common among women and those with a higher education. Lower income was associated with the use of mind-body therapies, whereas the other three CAM modalities were associated with higher income.

The authors concluded that help-seeking differed according to the health problem, something that should be acknowledged by clinical professionals to ensure safe care. The findings also point towards possible socioeconomic inequalities in health service use.

As I said, this is one of the rare surveys that is worth studying in some detail. This is mainly because it is rigorous and its results are clearly presented. Much of what it reports has been known before (for instance, we showed that the use of CAM in the UK was 26% which ties in perfectly with the 21% figure considering that here only 4 CAMs were included), but it is undoubtedly valuable to see it confirmed based on sound methodology.

Apart of what the abstract tells us, there are some hidden gems from this paper:

  • 8% of CAM users had used CAM exclusively (alternative use), without any visits to biomedical professionals in the last 12 months. This may look like a low figure, but I would argue that it is worryingly high considering that alternative usage of CAM has the potential to hasten patients’ deaths.
  • The most frequently used CAM treatment was massage therapy, used by 11.9% of the population, followed by homeopathy (5.7%), osteopathy (5.2%), herbal treatments (4.6%), acupuncture (3.6%), chiropractic (2.3%), reflexology (1.7%) and spiritual healing (1.3%). Other modalities (Chinese medicine, acupressure and hypnotherapy) were used by around by 1% or less. The figure for homeopathy is MUCH smaller that the ones homeopaths want us to believe.
  • About 9% of healthy survey-participants had used at least one of the CAM modalities during the last 12 months. One can assume that this usage was mostly for disease-prevention. But there is no good evidence for CAM to be effective for this purpose.
  • The highest ORs for the use of Traditional Asian Medical Systems were found in Denmark, Switzerland and Israel, followed by Austria, Norway and Sweden. The highest OR for the use of Alternative Medical Systems was found in Lithuania, while manual therapies were most commonly used in Finland, Austria, Switzerland, Germany and Denmark. Moreover, Denmark, Ireland, Slovenia and Lithuania had the highest ORs for using mind-body therapies. France, Spain and Germany presented a common pattern, with relatively similar use of the different modalities. Poland and Hungary had low ORs for use of the different CAM modalities.

But by far the nicest gem, however, comes from my favourite source of misinformation on matters of health, WDDTY. They review the new survey and state this: The patients are turning to alternatives for a range of chronic conditions because they consider the conventional therapy to be inadequate, the researchers say. Needless to point out that this is not a theme that was addressed by the new survey, and therefore its authors also do not draw this conclusion.
