I have often remarked on the fact that, in alternative medicine, more surveys get published than in any other medical field. Typically these surveys are not just useless but overtly counter-productive:

  • they tend to be of very poor quality;
  • their results are not generalizable and thus meaningless;
  • they show that a sizable proportion of the population uses alternative therapies, pay out of their own pocket for them, and are satisfied with them;
  • the authors then state that it must be unfair that only the affluent can benefit from alternative medicine;
  • eventually, the conclusion is reached that alternative medicine should be paid for by the healthcare system and be free for all at the point of usage.

Therefore, I find that it is a waste of time to even read surveys of alternative medicine usage. But every now and then, one does come along that is worth discussing – like this one, for instance.

The survey evaluated dietary supplements (DS) usage by US adults aged ≥60 y to characterize the use of DSs, determine the motivations for use, and examine the associations between the use of DSs and selected demographic, lifestyle, and health characteristics. Data from 3469 older adults aged ≥60 y from the 2011-2014 NHANES were analyzed. DSs used in the past 30 d were ascertained via an interviewer-administered questionnaire in participants’ homes. The prevalence of overall DS use and specific types of DSs were estimated. The number of DSs reported and the frequency, duration, and motivation(s) for use were assessed. Logistic regression models were constructed to examine the association between DS use and selected characteristics.

Seventy percent of older adults reported using ≥1 DS in the past 30 d; 54% of users took 1 or 2 products, and 29% reported taking ≥4 products. The most frequently reported products were multivitamin or mineral (MVM) (39%), vitamin D only (26%), and omega-3 fatty acids (22%). Women used DSs almost twice as often as men. Those not reporting prescription medications were less likely to take a DS than those reporting ≥3 prescription medications. The most frequently reported motivation for DS use was to improve overall health (41%).

The authors concluded that the use of DSs among older adults continues to be high in the United States, with 29% of users regularly taking ≥4 DSs, and there is a high concurrent usage of them with prescription medications.

I find these data impressive – but not in a positive sense, I hasten to add.

The level of DS use in the US is staggering. Considering that 90% (my estimate) of the supplements are completely useless, the amount of money that is being wasted is huge. Even more concerning is the frequency of drug interactions that are being provoked by DS-intake.

And what’s the solution?

Obviously, it is better information for consumers (which is easier said than done – but I am trying my best!).

According to Wikipedia, “the Bundesverband der Pharmazeutischen Industrie (BPI) with headquarters in Berlin is an Eingetragener Verein and the German industry association/trade group for the pharmaceutical industry. It represents 240 German pharmaceutical and Biotech companies in with altogether approximately 70,000 employees. BPI has an office in Brussels. The focus of the BPI is on political consulting and public relations on the EU-level.” 

The BPI has recently published a remarkable press-release about homeopathy. As it is in German, I will translate it for you (and append the original text for those who can read German).


Homeopathy is a recognised and proven therapy for patients in Germany [1]. This is demonstrated by a new, BPI-sponsored survey [2]. About half of all questioned had experience with homeopathic remedies [3]. More than 70% of those people are satisfied or very satisfied with their effectiveness and safety [4].

“Homeopathic remedies are important for many patients in Germany”[3], says Dr. Norbert Gerbsch, deputy chair of the BPI. ” If therapists and patients use them correctly, they can support the therapeutic success [5]. Therefore, they should be recognised by conventional medicine as an integrative medicine [5] – that is what patients in Germany clearly want [6].”

Two thirds of the people surveyed think it is important or very important, that therapies like anthroposophical medicine and homeopathy are supported politically next to conventional medicine [7]. More than 70% find it personally important or very important that health insurances pay for selected anthroposophical and homeopathic services [8]. More than 80% said they would favour this. Thus, the majority is for keeping homeopathy amongst the services that can be chosen by the insurances for reimbursement [8].

Dr. Norbert Gerbsch: “The survey proves that very many individuals integrate, use and treasure homeopathy as an additional and usually safe therapy [3]. Those who aim at curtailing therapeutic freedom patronise numerous patients in Germany who can benefit from it [9]. There are numerous diseases for which homeopathy can be used as an integrative therapeutic option [10]. Thus, many conventional physicians employ homeopathic and anthroposophic remedies in parallel to guideline-orientated medicine [3, 11].”

(Homöopathie ist eine anerkannte und bewährte Therapieform für Patienten in Deutschland. Das belegt eine neue, vom BPI beauftragte Forsa-Umfrage. Rund die Hälfte der Befragten hat demnach bereits Erfahrung mit homöopathischen Arzneimitteln. Über 70 Prozent von ihnen sind zufrieden oder sehr zufrieden mit der Wirksamkeit und Verträglichkeit.

„Homöopathische Arzneimittel haben für viele Patienten in Deutschland einen hohen Stellenwert“, sagt Dr. Norbert Gerbsch, stellvertretender BPI-Hauptgeschäftsführer. „Wenn Behandler und Patienten sie richtig und verantwortungsvoll einsetzen, kann sie den Therapieerfolg unterstützen. Sie sollte insofern als wichtige Ergänzung der Schulmedizin im Sinne einer Integrativen Medizin anerkannt werden – das wünschen sich die Patienten in Deutschland eindeutig.“

Fast zwei Drittel der von Forsa Befragten finden es wichtig bis sehr wichtig, dass sich die Politik neben schulmedizinischen Behandlungsmethoden auch aktiv für Heilmethoden wie etwa Homöopathie oder Anthroposophische Medizin einsetzt. Über 70 Prozent finden es persönlich wichtig bis sehr wichtig, dass Krankenkassen ihren Versicherten auch die Kosten für ausgewählte Leistungen aus dem Bereich der homöopathischen Medizin erstatten. Mit über 80 Prozent überdurchschnittlich häufig plädieren Befragte mit Homöopathie-Erfahrung für die Kostenübernahme ausgewählter Leistungen durch die Krankenkassen. Damit stimmt die Mehrheit für den Erhalt der Homöopathie im Rahmen von sogenannten Satzungsleistungen, die von den Krankenkassen individuell festgelegt werden können.

Dr. Norbert Gerbsch: „Die Umfrage belegt, dass sehr viele Menschen Homöopathie als ergänzende und in der Regel nebenwirkungsarme Therapieoption in die Behandlung integrieren, sie nutzen und achten. Wer die Therapiefreiheit und -vielfalt beschneiden will, bevormundet zahlreiche Patienten in Deutschland, die davon profitieren können. Es gibt eine Vielzahl an Erkrankungen, bei denen homöopathische Arzneimittel als integraler Bestandteil von Therapien einsetzbar sind. So nutzen viele Schulmediziner neben dem gesamten Spektrum der leitlinienorientierten Medizin gleichzeitig die integrativen Angebote der Homöopathie und Anthroposophischen Medizin.“)


I have rarely seen such an unscientific, irrational, nonsensical and promotional comment from an organisation and an individual that should know better. Mr. Gerbsch studied biotechnology and graduated in 1997 in bioprocess engineering. He headed a scientific team following his promotion to director of a trans-departmental research topic with 13 professorships at the Technical University of Berlin. He later took on responsibilities as commissioner, officer and director of various companies. Since 2006, Mr. Gerbsch works as department manager of biotechnology / research & development at BPI and is responsible for the biotechnology department and innovation & research committee.

Here are just a few short points of criticism referring to the numbers I have added in my translation:

  1. Homeopathy is recognised and proven to be a pure placebo-therapy.
  2. A survey of this nature can at best gauge the current opinion.
  3. Fallacy: appeal to popularity.
  4. Perceived effectiveness/safety is not the same as true effectiveness/safety.
  5. There is no good evidence for this statement.
  6. What patients want might be interesting, but it cannot determine what they need; medicine is not a supermarket!
  7. I suspect this is the result of a leading question.
  8. This is where the BPI discloses the aim of the survey and their comment about it: they want the German health insurances to continue paying for homeopathic and anthroposophical placebos because some of their member companies earn their money selling them. In other words, the BPI actively hinder progress.
  9. No, those who advocate not paying for placebos want to encourage progress in healthcare for the benefit of patients and society.
  10. “Can be used” is an interesting phraseology! It is true, one can use homeopathy – but one cannot use it effectively because it has no effect beyond placebo.
  11. Yes, many physicians are sadly more focussed on their own cash-flow than on the best interest of their patients. Not all that different from the BPI, it seems.

It is beyond me how an organisation like the BPI can produce such shamefully misleading, dangerous and unethical drivel. Not one word about the fact that all international bodies have condemned homeopathy as being a useless and dangerous placebo-therapy! Who ever thought that the BPI was an independent organisation (homeopathy manufacturers belong to its membership) has been proven wrong by the above press-release.

The BPI clearly needs reminding of their duty to inform the public responsibly. I recommend that the leading heads of this organisation urgently attend one course on critical thinking followed by another on medical ethics.

The purpose of this study was to evaluate whether the use of CAM among newly diagnosed breast cancer patients was associated with delays in presentation, diagnosis or treatment of breast cancer. A multi-centre cross-sectional design was used and the time points of the individual breast cancer patients’ journey from first visit, resolution of diagnosis and treatments were evaluated in six public hospitals in Malaysia.

All newly diagnosed breast cancer patients from 1st January to 31st December 2012 were recruited. Data were collected through medical records review and patient interview by using a structured questionnaire. Complementary and alternative medicine (CAM) was defined as the use of any methods and products not included in conventional allopathic medicine before commencement of treatments. Presentation delay was defined as time taken from symptom discovery to first presentation of more than 3 months. The time points were categorised to diagnosis delay was defined as time taken from first presentation to diagnosis of more than 1 month and treatment delay was defined as time taken from diagnosis to initial treatment of more than 1 month. Multiple logistic regression was used for analysis.

A total number of 340 patients participated in this study. The prevalence of CAM use was 46.5% (n = 158). Malay ethnicity (OR 3.32; 95% CI: 1.85, 5.97) and not interpreting symptom as cancerous (OR 1.79; 95% CI: 1.10, 2.92) were significantly associated with CAM use. The use of CAM was associated with delays in presentation (OR 1.65; 95% CI: 1.05, 2.59), diagnosis (OR 2.42; 95% CI: 1.56, 3.77) and treatment of breast cancer (OR 1.74; 95% CI: 1.11, 2.72) on univariate analyses. However, after adjusting with other covariates, CAM use was associated with delays in presentation (OR 1.71; 95% CI: 1.05, 2.78) and diagnosis (OR 2.58; 95% CI: 1.59, 4.17) but not for treatment of breast cancer (OR 1.58; 95% CI: 0.98, 2.55).

The authors concluded that the prevalence of CAM use among the breast cancer patients is high. Women of Malay ethnicity and not interpreting symptom as cancerous were significantly associated with CAM use. The use of CAM had significantly associated with delay in presentation and resolution of diagnosis. Difficulty in obtaining all medical records may have excluded patients who experienced delays in presentation, diagnosis or treatment but every precaution and resources were utilized to obtain record. This study suggests further evaluation of access to breast cancer care is needed as poor access may promote the use of CAM. However, since public hospitals in Malaysia are heavily subsidized and readily available to the population, CAM use may impact delays in presentation and diagnosis.

We know from previous studies that

  • CAM-use is associated with poor adherence to cancer treatments,
  • using CAM as an alternative to conventional treatments results in shorter survival of cancer patients,

and now we also know that CAM-use is associated with delayed presentation and diagnosis of cancer. This latter effect can have consequences that are just as serious as the other two. The later cancer is diagnosed, the poorer the prognosis and the shorter the survival.

These findings indicate that all healthcare professionals should be vigilant and inform patients as well as the general public that CAM-users are exposed to considerable dangers.

A new survey from the Frazer Institute, an independent, non-partisan Canadian public policy think-tank, suggests that more and more Canadians are using alternative therapies. In 2016, massage was the most common type of therapy that Canadians used over their lifetime with 44 percent having tried it, followed by chiropractic care (42%), yoga (27%), relaxation techniques (25%), and acupuncture (22%). Nationally, the most rapidly expanding therapies over the past two decades or so (rate of change between 1997 and 2016) were massage, yoga, acupuncture, chiropractic care, osteopathy, and naturopathy. High dose/mega vitamins, herbal therapies, and folk remedies appear to be in declining use over that same time period.

“Alternative treatments are playing an increasingly important role in Canadians’ overall health care, and understanding how all the parts of the health-care system fit together is vital if policymakers are going to find ways to improve it,” said Nadeem Esmail, Fraser Institute senior fellow and co-author of Complementary and Alternative Medicine: Use and Public Attitudes, 1997, 2006 and 2016.

The updated survey of 2,000 Canadians finds more than three-quarters of Canadians — 79 per cent — have used at least one complementary or alternative medicine (CAM) or therapy sometime in their lives. That’s an increase from 74 per cent in 2006 and 73 per cent in 1997, when two previous similar surveys were conducted. In fact, more than one in two Canadians (56 per cent) used at least one complementary or alternative medicine or therapy in the previous 12 months, an increase from 54 per cent in 2006 and 50 per cent in 1997.

And Canadians are using those services more often, averaging 11.1 visits in 2016, compared to fewer than nine visits a year in both 2006 and 1997. In total, Canadians spent $8.8 billion on complementary and alternative medicines and therapies last year, up from $8 billion (inflation adjusted) in 2006.

The majority of respondents — 58 per cent — support paying for alternative treatments privately and don’t want them included in provincial health plans. Support for private payment is even highest (at 69 per cent) among 35- to 44-year-olds. “Complementary and alternative therapies play an increasingly important role in Canadians’ overall health care, but policy makers should not see this as an invitation to expand government coverage — the majority of Canadians believe alternative therapies should be paid for privately,” Esmail said.

This seems to be a good survey, and it offers a host of interesting information. Yet, it also leaves many pertinent questions unanswered. The most important one might be WHY?

Why are so many people trying treatments which clearly are unproven or disproven?

Enthusiasts would obviously say this is because they are useful in some way. I would, however, point out that the true reason might well be that consumers are systematically mislead about the value of alternative therapies, as I have shown on this blog so many times.

Nevertheless, this seems to be a good survey – there are hundreds, if not thousands of surveys in the realm of alternative medicine which are of such deplorable quality that they do not deserve to be published at all – but even with a relatively good survey, we need to be cautious. For instance, I have no difficulty designing a questionnaire that would guarantee a result of 100% prevalence of alternative medicine usage. All I would need to do is to include the following two questions:

  • Have you ever used plant-based products for your well-being or comfort?
  • Have you ever prayed while being ill?

Drinking a cup of tea would already have to prompt a positive reply to the 1st question. And if you answer yes to the 2nd question, it would be interpreted as using prayer as a therapy.

I think, I rest my case.

The aim of this paper was to systematically review surveys of 12-month prevalence of homeopathy use by the general population worldwide. Studies were identified via database searches to October 2015. Study quality was assessed using a six-item tool. All estimates were in the context of a survey which also reported prevalence of any complementary and alternative medicine use. A total of 36 surveys were included. Of these, 67% met four of six quality criteria.

Twelve-month prevalence of treatment by a homeopath was reported in 24 surveys of adults (median 1.5%, range 0.2–8.2%). Estimates for children were similar to those for adults. Rates in the USA, UK, Australia and Canada all ranged from 0.2% to 2.9% and remained stable over the years surveyed (1986–2012). Twelve-month prevalence of all use of homeopathy (purchase of over-the-counter homeopathic medicines and treatment by a homeopath) was reported in 10 surveys of adults (median 3.9%, range 0.7–9.8%) while a further 11 surveys which did not define the type of homeopathy use reported similar data. Rates in the USA and Australia ranged from 1.7% to 4.4% and remained stable over the years surveyed. The highest use was reported by a survey in Switzerland where homeopathy is covered by mandatory health insurance.

The authors concluded that each year a small but significant percentage of these general populations use homeopathy. This includes visits to homeopaths as well as purchase of over-the-counter homeopathic medicines.

These data thus indicate that the percentage of the adult general population using homeopathy over the previous 12 months was in the range of 0.7–9.8%, with a median estimate of 3.9%, and the percentage accessing treatment by a homeopath over the previous 12 months was in the range of 0.2–8.2%, with a median estimate of 1.5%. The data also suggest that, over the last few decades, use of homeopathy has remained fairly stable. These facts are in sharp contrast to the claims by homeopaths that:

  • Homeopathy is hugely popular.
  • Homeopathy is being used by more and more people across the globe.
  • Homeopathy is the medicine of the future.

The well-documented and undeniable unpopularity of homeopathy begs the question, I think, why so many people seem to get so excited about homeopathy. The level of usage is nothing to write home about! Therefore, why don’t we just put it down to an aberration like believing the earth is flat? Why don’t we just concede that some minor, harmless stupidity will always exist in some people’s minds?

Here are some reasons why:

  • It is not about the amount of people using homeopathy, but about the principle that any of the increasingly scarce public funds for healthcare are wasted on something as irrational and useless as homeopathy.
  • Homeopathy makes a mockery of EBM.
  • Homeopathy and homeopaths are by no means harmless.
  • Homeopaths tell too many lies to be allowed to get away with them.
  • Homeopathy and its followers systematically undermine rational thought.



The British Chiropractic Association (BCA) has lost all credibility after suing Simon Singh for drawing the public’s attention to the fact that they were ‘happily promoting bogus treatments’. Now, it seems, they are trying to re-establish themselves with regular, often bogus or dubious pronouncements about back pain. It looks as though they have learnt nothing. A recent article in THE INDEPENDENT is a good example of this ambition, I think:


Skinny jeans and coats with big fluffy hoods can contribute to painful back problems, chiropractors have warned.

Nearly three-quarters of women have experienced back pain, according to a survey by the British Chiropractic Association (BCA), who said fashionable clothing including backless shoes, oversized bags and heavy statement jewellery were partly to blame.

Wearing very tight jeans can restrict mobility and force other muscles to strain as they try to compensate for the resulting change in posture, chiropractor Rishi Loatey told The Independent.

“If they’re incredibly tight, you won’t be able to walk as you normally would,” he said.

“You’ve got a natural gait, or stride, that you would take, and the knee, hip and lower back all move to minimise the pressure coming up through the joints.

“However, if one of those areas isn’t moving as it should be, it’s going to cause more pressure elsewhere.”

While 73 per cent of women from a sample of more than 2,000 said they have had back pain, more than a quarter – 28 per cent – said they were aware their clothing affects their posture and back and neck pain, but did not take this into account when choosing what to wear.

Lower back pain is the most common cause of disability worldwide, with 9.4 per cent of people suffering from it, according to a previous study.

High heels, which cause muscles in the back of the leg and the calf to tighten and pull on the pelvis differently, have long been culprits of back pain.

A number of high-profile campaigns against “sexist” dress codes requiring women to wear high heels at work have made reference to this fact.

But backless shoes, flimsy ballet pumps and some soft boots can also damage your back if they are worn too often, said Mr Loatey.

“If you imagine the back of a shoe, the bit that goes round the back is supposed to be quite firm, so it grips the rear foot,” he said. “If you don’t have that, then your foot is more mobile in the shoe.”

“If they’re not the right size, they’re a bit loose or they don’t have the bit at the back, you’re almost gripping the shoe as you walk, which again changes the way you walk,” said Mr Loatey, adding that ideally shoes should be laced up at the front to make sure the foot is held firmly.

A third of women surveyed by the BCA were unaware that their clothing choices could harm their backs and necks.

Mr Loatey said people should try and wear clothes that allow them to move more freely. Heavy hoods and over-shoulder bags can both restrict movement.

They should also consider limiting the amount of time they spent wearing high heels or backless shoes and consider travelling to work or social events in trainers or other well-supported shoes instead, he said.


This piece strikes me as pure promotion of chiropractic – health journalism at its worse, I’d say. What is more objectionable than the promotion, it is full of half truths, ‘alternative facts’ and pure invention. Let me list a few statements that I find particularly doggy:

  1. “Skinny jeans and coats with big fluffy hoods can contribute to painful back problems.” Do they have any evidence for this? I don’t know of any!
  2. “…fashionable clothing including backless shoes, oversized bags and heavy statement jewellery were partly to blame [for back problems].” Idem!
  3. “Wearing very tight jeans can restrict mobility and force other muscles to strain…” Idem!
  4. “…it’s going to cause more pressure elsewhere.” Idem!
  5. 28% of women said “they were aware their clothing affects their posture and back and neck pain, but did not take this into account when choosing what to wear.” To make the findings from a survey look like scientific evidence for cause and effect is at best misleading, at worst dishonest.
  6. “…according to a previous study“. It turns out that this previous study was of occupational back pain which has nothing to do with tight jeans etc.
  7. “High heels, which cause muscles in the back of the leg and the calf to tighten and pull on the pelvis differently, have long been culprits of back pain.” A link to the evidence would be nice – if there is any.
  8. “But backless shoes, flimsy ballet pumps and some soft boots can also damage your back – if they are worn too often…” Evidence needed – if there is any.
  9. “Mr Loatey said people should try and wear clothes that allow them to move more freely. Heavy hoods and over-shoulder bags can both restrict movement.” Concrete recommendations require concrete evidence or a link to it.
  10. Women “should also consider limiting the amount of time they spent wearing high heels or backless shoes and consider travelling to work or social events in trainers or other well-supported shoes instead.” Idem.

At this point congratulations are in order, I feel.

Firstly to THE INDEPENDENT for publishing one of the most inadequate health-related article which I have seen in recent months.

Secondly to the BCA for their stubborn determination to ‘happily promoting bogus’ notions. Instead of getting their act together when found out to advertise quackery in 2008, they sued Simon Singh (unsuccessfully, I hasten to add). Instead of cutting out the nonsense once and for all, they now promote populist ‘alternative facts’ about the causes of back pain. Instead of behaving like a professional organisation that promotes high standards and solid evidence, they continue to do the opposite.

One cannot but be impressed with so much intransigence.

The notorious tendency of pharmacist to behave like shop-keepers when it comes to the sale of bogus remedies has been the subject of this blog many times before. In my view, this is an important subject, and I will therefore continue to report about it.

On the website of the AUSTRALIAN JOURNAL OF PHARMACY (AJP), we find interesting new data on Australian pharmacists’ love affair with bogus alternative medicine. The AJP recently ran a poll asking readers: “Do you stock Complementary Medicines (CMs) in your pharmacy?” The results of this little survey so far show that 54% of all participating pharmacists say they stock CMs, including homeopathic products. About a quarter (28%) of respondents stock CMs but not homeopathic products. And 9% said they “only stock evidence-based CMs”. Three percent completely refuse to stock CMs, while 2% stock them but with clear in-store labels saying that they may not work. One person stated they stock CMs but have recently decided to no longer do so.

The President of the Pharmaceutical Society of Australia (PSA) Joe Demarte commented on these findings: “The latest survey results, showing over 40% of pharmacists are adhering to PSA’s Code of Ethics on complementary medicines, are very encouraging… However it’s disappointing that some pharmacists are still stocking homeopathy products, which are not supported by PSA’s Code of Ethics or our Position Statement on Complementary Medicines… Irrespective of the products stocked in a pharmacy, the important thing is when discussing the use of complementary medicines with consumers, pharmacists must ensure that consumers are provided with the best available information about the current evidence for efficacy, as well as information on any potential side effects, drug interactions and risks of harm… It’s important for pharmacists to provide a fair, honest and balanced view of the current evidence available on all complementary medicines,” Demarte added.

NSW pharmacist Ian Carr, who is a member of the Friends of Science in Medicine group, commented that many pharmacists may not have much choice when it comes to stocking complementary and alternative medicines. “CMs policy is not being filtered through the professional assessment of the pharmacist… It’s basically a business deal with the franchise, and as a pharmacist taking on a franchise you’ve basically got to sign those rights away about what you get to sell. Some of the chains offer basically everything that is available, no questions asked. As an independent pharmacist I am able to make my own decisions about what to stock… We’ve got a ‘de-facto’ corporatisation happening with marketing groups and franchises, and I’m concerned the government will look at this trend and ask, why are we not deregulating the industry to reflect the apparent reality of pharmacy today? We’re only playing into the hands of people who want deregulation… We should be telling people in no uncertain terms that if something is on the shelf it doesn’t mean it’s been assessed or approved by the TGA… There is no doubt that there has been a long-term relationship between the supplement industry and pharmacy. But it was also a few decades ago that researchers started applying the concept of evidence-based medicine to healthcare generally. That should have been the point where we said, ‘we’re not just going to be a conduit for your products without questioning their basis in evidence’. That’s where we lost the plot. The question now is: where do we draw that line? I’m really trying to say to my fellow pharmacists: Please let us reassess the unquestioning support of the CM industry, or we’ll all be tarred with the same brush. I and many others are concerned about – and fighting for – the reputation of the pharmacy profession.”

A BMC Complementary and Alternative Medicine survey by researchers from Alfred Hospital in Melbourne found that 92% thought pharmacists should provide safety information about CMs, while 93% thought it important for pharmacists to be knowledgeable about CMs. This shows a huge divide between what is happening in Australian pharmacy on the one side and ethical demands or public opinion on the other side. What is more, there is little reason to believe that the situation in other countries is fundamentally different.

And did you notice this little gem in the comments above?  “…over 40% of pharmacists are adhering to PSA’s Code of Ethics…” – the PSA president finds this ‘VERY ENCOURAGING’.

When I saw this, I almost fell off my chair!

Does the president know that this means that 60% of his members are violating their own code of ethics?

Is that truly VERY ENCOURAGING, I ask myself.

My answer is no, this is VERY WORRYING.


Yes, to a large extend, quacks make a living by advertising lies. A paper just published confirms our worst fears.

This survey was aimed at identifying the frequency and qualitative characteristics of marketing claims made by Canadian chiropractors, naturopaths, homeopaths and acupuncturists relating to the diagnosis and treatment of allergy and asthma.

A total of 392 chiropractic, naturopathic, homeopathic and acupuncture clinic websites were located in 10 of the largest metropolitan areas in Canada. The main outcome measures were: mention of allergy, sensitivity or asthma, claim of ability to diagnose allergy, sensitivity or asthma, claim of ability to treat allergy, sensitivity or asthma, and claim of allergy, sensitivity or asthma treatment efficacy. Tests and treatments promoted were noted as qualitative examples.

The results show that naturopath clinic websites had the highest rates of advertising at least one of diagnosis, treatment or efficacy for allergy or sensitivity (85%) and asthma (64%), followed by acupuncturists (68% and 53%, respectively), homeopaths (60% and 54%) and chiropractors (33% and 38%). Search results from Vancouver were most likely to advertise at least one of diagnosis, treatment or efficacy for allergy or sensitivity (72.5%) and asthma (62.5%), and results from London, Ontario were least likely (50% and 40%, respectively). Of the interventions advertised, few are scientifically supported; the majority lack evidence of efficacy, and some are potentially harmful.

[Legend to figure above: Percentage of alternative medicine clinic websites advertising at least one of diagnosis, treatment or efficacy for allergy/sensitivity or asthma. Presenting the data in this way demonstrates that the Canadian naturopath, homeopath and acupuncturist websites studied have >50% rates of making at least one health-related claim for both allergy/sensitivity and asthma.]

The authors concluded that the majority of alternative healthcare clinics studied advertised interventions for allergy and asthma. Many offerings are unproven. A policy response may be warranted in order to safeguard the public interest.

In the discussion section, the authors state: “These claims raise ethical issues, because evidence in support of many of the tests and treatments identified on the websites studied is lacking. For example, food-specific IgG testing was commonly advertised, despite the fact that the Canadian Society of Allergy and Clinical Immunology has recommended not to use this test due to the absence of a body of research supporting it. Live blood analysis, vega/electrodiagnostic testing, intravenous vitamin C, probiotics, homeopathic allergy remedies and several other tests and treatments offered all lack substantial scientific evidence of efficacy. Some of the proposed treatments are so absurd that they lack even the most basic scientific plausibility, such as ionic foot bath detoxification…

Perhaps most concerning is the fact that several proposed treatments for allergy, sensitivity or asthma are potentially harmful. These include intravenous hydrogen peroxide, spinal manipulation and possibly others. Furthermore, a negative effect of the use of invalid and inaccurate allergy testing is the likelihood that such testing will lead to alterations and exclusions in diets, which can subsequently result in malnutrition and other physiological problems…”

This survey originates from Canada, and one might argue that elsewhere the situation is not quite as bad. However, I would doubt it; on the contrary, I would not be surprised to learn that, in some other countries, it is even worse.

Several national regulators have, at long last, become aware of the dangers of advertising of outright quackery. Consequently, some measures are now beginning to be taken against it. I would nevertheless argue that these actions are far too slow and by no means sufficiently effective.

We easily forget that asthma, for instance, is a potentially life-threatening disease. Advertising of bogus claims is therefore  much more than a forgivable exaggeration aimed at maximising the income of alternative practitioners – it is a serious threat to public health.

We must insist that regulators protect us from such quackery and prevent the serious harm it can do.

Alternative medicine suffers from what might be called ‘survey overload’: there are far too much such investigations and most of them are of deplorably poor quality producing nothing of value except some promotion for alternative medicine. Yet, every now and then, one finds a paper that is worth reading, and I am happy to say that this survey (even though it has several methodological shortcomings) belongs in this category.

This cross-sectional assessment of the views of general practitioners towards chiropractors and osteopaths was funded by the Department of Chiropractic at Macquarie University. It was designed as a quantitative descriptive study using an anonymous online survey that included closed and open-ended questions with opportunities provided for free text. The target population was Australian general practitioners. Inclusion criteria included current medical registration, membership of the Royal Australian College of General Practitioners and currently practicing as a general practitioner in Australia. The data being reported here were collected between May and December, 2014.

There were 630 respondents to the online survey during this period representing a response rate of 2.6 %. Results were not uniform for the two professions. More general practitioners believed chiropractic education was not evidence-based compared to osteopathic education (70 % and 50 % respectively), while the scope of practice was viewed as similar for both professions. A majority of general practitioners had never referred a patient to either profession (chiropractic: 60 %; osteopathy: 66 %) and indicated that they would not want to co-manage patients with either profession. Approximately two-thirds of general practitioners were not interested in learning more about their education (chiropractors: 68 %; osteopaths: 63 %).

The authors concluded that this study provides an indication of the current views of Australian general practitioners towards chiropractors and osteopaths. The findings suggest that attitudes may have become less favourable with a growing intolerance towards both professions. If confirmed, this has the potential to impact health service provision. The results from this cross-sectional study suggest that obtaining representative general practitioner views using online surveys is difficult and another approach is needed to supplement or replace the current recruitment strategy.

The authors do not speculate on the reasons why the attitudes of general practitioners towards chiropractic and osteopathy might have become more critical. Therefore I decided to offer a few possibilities here. The more negative views could be due to:

  • better education of general practitioners,
  • tightening of healthcare budgets,
  • recent ‘bad press’ and loss of reputation (for instance, the BCA’s libel action against Simon Singh),
  • the work of sceptics in informing the public about the numerous bogus claims made by osteopaths and chiropractors,
  • the plethora of overtly bogus claims which nevertheless continue to be made by these practitioners on a daily basis,
  • a more general realisation that these therapies can cause very serious harm,
  • a mixture of the above factors.

Whatever the reasons are, the finding that there now seems to be a growing scepticism (in Australia, but hopefully elsewhere as well) about the value of chiropractic and osteopathy is something that cheers me up no end.

Chiropractors may not be good at treating diseases or symptoms, but they are certainly good at promoting their trade. As this trade hardly does more good than harm, one could argue that chiropractors are promoting bogus and potentially harmful treatments to fill their own pockets.

Does that sound too harsh? If you think so, please read what Canadian researchers have just published:

This study aimed to investigate the presence of critiques and debates surrounding efficacy and risk of Spinal Manipulative Therapy (SMT) on the social media platform Twitter. Specifically, it examined whether there is presence of debate and whether critical information is being widely disseminated.

An initial corpus of 31,339 tweets was compiled through Twitter’s Search Application Programming Interface using the query terms “chiropractic,” “chiropractor,” and “spinal manipulation therapy.” Tweets were collected for the month of December 2015. Post removal of tweets made by bots and spam, the corpus totalled 20,695 tweets, of which a sample (n=1267) was analysed for sceptical or critical tweets.

The results showed that there were 34 tweets explicitly containing scepticism or critique of SMT, representing 2.68% of the sample (n=1267). As such, there is a presence of 2.68% of tweets in the total corpus, 95% CI 0-6.58% displaying explicitly sceptical or critical perspectives of SMT. In addition, there are numerous tweets highlighting the health benefits of SMT for health issues such as attention deficit hyperactivity disorder (ADHD), immune system, and blood pressure that receive scant critical attention. The presence of tweets in the corpus highlighting the risks of “stroke” and “vertebral artery dissection” is also minute (0.1%).

The authors drew the following conclusions: In the abundance of tweets substantiating and promoting chiropractic and SMT as sound health practices and valuable business endeavors, the debates surrounding the efficacy and risks of SMT on Twitter are almost completely absent. Although there are some critical voices of SMT proving to be influential, issues persist regarding how widely this information is being disseminated.

I have no doubt that this paper will be sharply criticised by chiropractors, other manipulators and lobbyists of quackery. Yet I think it is an interesting and innovative approach to describe what is and is not being said on public media. The fact that chiropractors hardly ever publicly criticise or challenge each other on Twitter or elsewhere for even the most idiotic claims is, in my view, most telling.

Few people would doubt that such platforms have become hugely important in forming public opinions, and it seems safe to assume that consumers views about SMT are strongly influenced by what they read on Twitter. If we accept this position, we also have to concede that Twitter et al. are a potential danger to public health.

The survey is, however, not flawless, and the authors are the first to point that out: Given the nature of Twitter discussions and the somewhat limited access provided by Twitter’s API, it can be challenging to capture a comprehensive collection of tweets on any topic. In addition, other potential terms such as “chiro” and “spinal adjustment” are present on Twitter, which may produce datasets with somewhat different results. Finally, although December 2015 was chosen at random, there is nothing to suggest that other time frames would be significantly similar or different. Despite these limitations, this study highlights the degree to which discussions of risk and critical views on efficacy are almost completely absent from Twitter. To this I would add that a comparison subject like nursing or physiotherapy might have been informative, and that somehow osteopaths have been forgotten in the discussion.

The big question, of course, is: what can be done about creating more balance on Twitter and elsewhere? I wish I had a practical answer. In the absence of such a solution, all I can offer is a plea to everyone who is able of critical thinking to become as active as they can in busting myths, disclosing nonsense and preventing the excesses of harmful quackery.

Let’s all work tirelessly and effectively for a better and healthier future!
