Homeopathy has a long history in Canada. In 1842, James Lilli was probably the first Canadian homeopath to begin practicing in Toronto. Joseph J. Lancaster, who had studied in New York, began practicing sometime in the 1840s in Ontario. The ‘Homeopathic Medical Society of Canada’ was established in 1854 in Hamilton, Ontario.
Since these early days much has changed. At present, all health care professions in Ontario are governed by the ‘Regulated Health Professions Act’ which allows all health-care professions the same right to practice. This law upholds the belief that the public has the right to choose what health care it wishes, and that the government should only intervene to regulate where a profession poses a significant risk of harm to the public. Only allopathic professions are currently regulated, and, in Ontario, doctors are censured if they practice homeopathy.
All schools of homeopathy in Canada offer ‘diplomate status’ and all offer three-year, part-time courses (one or two weekends per month plus perhaps one or two evenings per week). There are no legal doctorate or university degree programs for homeopathy in Canada. A doctorate in any field other than allopathic medicine cannot legally be used while practicing homeopathy.
I have been reliably informed that the regulation of homeopathy in Ontario is about to change. A transitional council of the ‘College of Homeopaths of Ontario’ had already been appointed in September 2009. The next step in the regulatory process is now imminent. On April 1 this year, Ontario will proclaim the ‘Homeopathy Act’. The bill will further empower the ‘College of Homeopaths of Ontario’. This regulatory body will hence forth have control over who gets to call themselves a homeopath. In addition, it will also have a complaint tracking system.
This moves comes only days after the ‘Australian National Health and Medical Research Council’ has published the most thorough and independent assessment of homeopathy in the history of this form of alternative therapy. It concluded that homeopathy should not be used to treat health conditions that are chronic, serious, or could become serious. People who choose homeopathy may put their health at risk if they reject or delay treatments for which there is good evidence for safety and effectiveness.
In view of the fact that homeopathy has been disproven as a treatment that fails to have a positive risk/benefit balance, the move of the regulators in Ontario seems pure madness to me. It sends the wrong signal to consumers and gives credibility to a form of quackery.
In a nutshell: EVEN THE BEST REGULATION OF NONSENSE WILL RESULT IN NONSENSE!
I have argued since many years that pharmacists should not be selling or promoting homeopathic and other remedies for which there is no proof of efficacy – the last time I published my view on this matter is even less than a week ago: Personally, I would go another step further and remind pharmacists who sell homeopathic remedies to the unsuspecting public that it is unethical to pretend they are more than placebos.
Despite my insistence and despite the fact that many agree with me (at least privately), there are precious few pharmacists who actually do something meaningful about the current situation. And there is very little visible change: in the UK, it is currently hard to find a pharmacy where homeopathic remedies are not on the shelves, and certainly all the major chains seem to put money before health care ethics.
I am, of course, speaking about the situation in the UK, France, Germany and some other European countries. Perhaps elsewhere things are different?
A NZ website seems to indicate that ‘down under’ the pharmacists are getting more active. Some strongly argue against unproven or disproven remedies in pharmacies:
Firstly, …it’s not a case that “pharmacists ‘should’ only be selling health products for which there is credible evidence of efficacy” (alterations mine, emboldened) but that they are obliged to—but choose not to. Their ethical guidelines state -
[PHARMACISTS] MUST:… Only purchase, supply or promote any medicine, complementary therapy, herbal remedy or other healthcare product where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.
…Secondly, the argument that ‘other businesses sell junk remedies therefore we shall’ is unsound. One of the key points about the ethical regulations for pharmacies is that customers should be able to walk into a store and have an expectation that the remedies within the store are basically sound. If other businesses elect to be unsound, that’s poor health practice, but no justification to do likewise. On the face of it, it would seem that the profit motive is ruling over sound and ethical practice.
Thirdly, that some GPs subscribe placebos should have no standing in this. There is some arguments for GPs to prescribe placebo remedies in some cases; others would argue that education is a better response in most cases. Either way—and just my opinion—it seems to me that GPs prescribing homeopathic remedies encourages people to think these have real remedial effects. I don’t work within the industry, but I am sure are ways of offering placebos that avoid using off-the-shelf commercial products. One might be that patients only get placebo ‘treatments’ via prescription.
…Fourthly, Pharmacy Today encourages that “pharmacies need to reconsider their stance in the light of this report”***. While this is an excellent idea, and one I thoroughly support, I suspect the underlying driver isn’t the report, but media presence on the topic. There is a long trail of evidence over many years showing that homeopathic remedies are not effective for anything.
The Australian study*** that prompted the latest round of interest drew this statement,
Based on the assessment of the evidence of effectiveness of homeopathy, NHMRC concludes that there are no health conditions for which there is reliable evidence that homeopathy is effective.
Homeopathy should not be used to treat health conditions that are chronic, serious, or could become serious. People who choose homeopathy may put their health at risk if they reject or delay treatments for which there is good evidence for safety and effectiveness. People who are considering whether to use homeopathy should first get advice from a registered health practitioner.* Those who use homeopathy should tell their health practitioner and should keep taking any prescribed treatments.
The National Health and Medical Research Council expects that the Australian public will be offered treatments and therapies based on the best available evidence.
…Why were the relevant professional bodies not onto this evidence sooner?…
I might add another one: why are the European professional bodies of pharmacy doing so little about this ongoing breach of their own ethical codes?
(*** the report that the author refers to is the one by the Australian National Health and Medical Research Council we discussed on this blog a few days ago.)
According to Bloomberg Markets, A Nelson & Co Ltd. manufactures and markets natural healthcare products. The company offers arnica creams that provide natural first aid for bruises; plant and flower based remedies that help in managing the emotional demands of everyday life; and over-the-counter homeopathic medicines for everyday ailments, such as relief from travel sickness and relief for the symptoms of hay fever. It also provides hemorrhoid relief creams and soothing hygienic wipes; anti-blemish range products for various skin types and age groups; multi-purpose cream that helps to soothe and restore skin; iron supplements; teething granules that provide relief from the symptoms and discomfort of teething; a range of creams, ointments, and sprays for a range of common skin conditions/complaints; and a range of commonly used herbal remedies. The company offers products for ailments, including aches and pains, mild anxiety, babies and children, colds and minor infections, digestion, emotional health, energy, everyday stresses, first aid, getting older, pets, quit smoking, skin, sleep, travel, and women’s health. It also operates a clinic; and a pharmacy that offers homeopathy and complementary healthcare products. The company offers its products through its pharmacy in the United Kingdom; and distributors in Europe, Latin America, and internationally. It also serves customers online. The company was formerly known as Armbrecht, Nelson & Co. The company was founded in 1860 and is based in London, United Kingdom with subsidiary offices in Boston, Massachusetts; and Hamburg, Germany. A Nelson & Co Ltd. operates as a subsidiary of Nelson and Russell Holdings Ltd.
In the journal ‘Chemist and Druggist’ we find an article informing us that, in 1930, Nelsons Homeopathic Pharmacy was approached by Dr Edward Bach who wanted help making and selling his products. He had created 38 flower remedies to rebalance emotions and later created an emergency remedy, a combination of five flower remedies that became Rescue. The relationship between Nelsons and the Dr Edward Bach Centre, based at Dr Bach’s former home at Mount Vernon in Oxfordshire, continues to this day and both the Bach Original Flower Remedies and Rescue are key ranges for Nelsons.
Nelson’s homeopathic pharmacy has a proud history:
Ernst Louis Armbrecht, a German pharmacist and disciple of Samuel Hahnemann, came to London and founded Nelsonsin 1860. Since then, Nelsons has been supplying homeopathic medicines. “Our wish today” they state “is the same as 152 years ago: to make homeopathy accessible and to provide the highest standards of medicine and advice.”
The highest standards of medicine and advice? It seems that the Advertising Standards Authority (ASA) disagrees. A recent ASA Adjudication on A Nelson & Co Ltd deals with an advertisement by Nelsons for ‘Bach Rescue Night’ which stated “I CAN’T SWITCH OFF…The RESCUE NIGHT range helps your mind switch off, so you can enjoy a natural night’s sleep”
A freelance health writer had challenged whether the claims “I can’t switch off … Rescue Night range helps your mind switch off, so you can enjoy a natural night’s sleep” was an authorised health claim in the EU Register of Nutrition and Health Claims for Foods (the EU Register).
The ASA noted that, according to EC Regulation 1924/2006 on Nutrition and Health Claims made on Foods (the Regulation), which was reflected in the CAP Code, only health claims which appeared on the list of authorised health claims (the Register) could be made in ads promoting foods, including food supplements. Health claims were defined as those that stated, suggested or implied that a relationship existed between a food category, a food or one of its constituents and health.
The ASA furthermore stated: We acknowledged Rescue Remedy’s assertion that their ad had not made specific claims to aid sleep or that it improved sleep. However, we considered that the use of visuals such as a crescent moon and stars on a dark background, that the letter ‘O’ in the word “OFF” resembled a simple on/ off light switch image, the text “… you can enjoy a natural night’s sleep” and the name of the product “Rescue Night” was likely to give the impression to consumers that it was a product that would aid sleep or that it would help consumers fall asleep easily. We understood that ‘unwanted thoughts’ was one reason why consumers might find it difficult to get to sleep and, again, considered this added to the impression that the product would contribute positively to sleep. We therefore considered that the ad made a health claim related to sleep involving a food item.
We understood that some Bach Flower Remedies contained levels of alcohol which would preclude them from bearing health claims altogether, however, we noted that Bach Rescue Night was alcohol free. We acknowledged Rescue Remedy’s points regarding EFSA and ‘on hold’ claims for botanicals. We understood that ‘on hold’ claims for such botanicals could be used in marketing, provided such use had the same meaning as the proposed claim and they were used in compliance with applicable existing national provisions (in this case the CAP Code). However, Rescue Remedy did not provide evidence that relevant proposed claims for white chestnut, or any of the other product ingredients were ‘on hold’. Nevertheless, we understood that there were no ‘on hold’ claims entered onto the Register for white chestnut or the other product ingredients. Furthermore, ‘on hold’ claims should also be supported with adequate substantiation which we did not receive.
Because the ad made health claims relating to Bach Rescue Night as a sleep aid and we had not seen evidence that relevant claims for the botanical ingredients contained in the product were ‘on hold’, we concluded that the ad breached the Code.
The ad breached CAP Code (Edition 12) rules 15.1, 15.1.1 and 15.7 (Food, food supplements and associated health or nutritional claims).
The ASA ruled that the ad must not appear again in its current form. We told A Nelson & Co Ltd t/a rescueremedy.co.uk not to make health claims for botanical ingredients if they did not comply with the requirements of the Regulation.
I am afraid that such a ruling will have very little effect on the sale of Bach Flower Remedies. In case you have any doubt, I should mention that these inventions of Dr Bach are not supported by good evidence. Here is the abstract of my systematic review on the subject:
Bach flower remedies continue to be popular and its proponents make a range of medicinal claims for them. The aim of this systematic review was to critically evaluate the evidence for these claims. Five electronic databases were searched without restrictions on time or language. All randomised clinical trials of flower remedies were included. Seven such studies were located. All but one were placebo-controlled. All placebo-controlled trials failed to demonstrate efficacy. It is concluded that the most reliable clinical trials do not show any differences between flower remedies and placebos.
Bach Flower Remedies have no effect whatsoever!
Come to think of it, this is not entirely true: they obviously keep the ASA busy, they exploit the gullible public, and they are clearly good for the cash flow at Nelson’s.
Reflexology is the treatment of reflex zones, usually on the sole of the feet, with manual massage and pressure. Reflexologists assume that certain zones correspond to certain organs, and that their treatment can influence the function of these organs. Thus reflexology is advocated for all sorts of conditions. Proponents are keen to point out that their approach has many advantages: it is pleasant (the patient feels well with the treatment and the therapist feels even better with the money), safe and cheap, particularly if the patient does the treatment herself.
Self-administered foot reflexology could be practical because it is easy to learn and not difficult to apply. But is it also effective? A recent systematic review evaluated the effectiveness of self-foot reflexology for symptom management.
Participants were healthy persons not diagnosed with a specific disease. The intervention was foot reflexology administered by participants, not by practitioners or healthcare providers. Studies with either between groups or within group comparison were included. The electronic literature searches utilized core databases (MEDLINE, EMBASE, Cochrane, and CINAHL Chinese (CNKI), Japanese (J-STAGE), and Korean databases (KoreaMed, KMbase, KISS, NDSL, KISTI, and OASIS)).
Three non-randomized trials and three before-and-after studies met the inclusion criteria. No RCTs were located. The results of these studies showed that self-administered foot reflexology resulted in significant improvement in subjective outcomes such as perceived stress, fatigue, and depression. However, there was no significant improvement in objective outcomes such as cortisol levels, blood pressure, and pulse rate. We did not find any randomized controlled trial.
The authors concluded that this study presents the effectiveness of self-administered foot reflexology for healthy persons’ psychological and physiological symptoms. While objective outcomes showed limited results, significant improvements were found in subjective outcomes. However, owing to the small number of studies and methodological flaws, there was insufficient evidence supporting the use of self-performed foot reflexology. Well-designed randomized controlled trials are needed to assess the effect of self-administered foot reflexology in healthy people.
I find this review quite interesting, but I would draw very different conclusions from its findings.
The studies that are available turned out to be of very poor methodological quality: they lack randomisation or rely on before/after comparisons. This means they are wide open to bias and false-positive results, particularly in regards to subjective outcome measures. Predictably, the findings of this review confirm that no effects are seen on objective endpoints. This is in perfect agreement with the hypothesis that reflexology is a pure placebo. Considering the biological implausibility of the underlying assumptions of reflexology, this makes sense.
My conclusions of this review would therefore be as follows: THE RESULTS ARE IN KEEPING WITH REFLEXOLOGY BEING A PURE PLACEBO.
Henry Louis Mencken (1880-1956) was an outspoken American journalist, essayist and literary critic famous for his vitriolic attacks on what he considered to be the hypocrisy of much of American life. In 1924, he published an essay on chiropractic which, I think, is still poignant today. I take the liberty of reproducing here in a slightly abbreviated form.
This preposterous quackery [chiropractic] flourishes lushly in the back reaches of the Republic, and begins to conquer the less civilized folk of the big cities. As the old-time family doctor dies out in the country towns, with no competent successor willing to take over his dismal business, he is followed by some hearty blacksmith or ice-wagon driver, turned into a chiropractor in six months, often by correspondence… [Chiropractic] pathology is grounded upon the doctrine that all human ills are caused by pressure of misplaced vertebrae upon the nerves which come out of the spinal cord — in other words, that every disease is the result of a pinch. This, plainly enough, is buncombe. The chiropractic therapeutics rest upon the doctrine that the way to get rid of such pinches is to climb upon a table and submit to a heroic pummeling by a retired piano-mover. This, obviously, is buncombe doubly damned.
…Any lout with strong hands and arms is perfectly equipped to become a chiropractor. No education beyond the elements is necessary. The takings are often high, and so the profession has attracted thousands of recruits — retired baseball players, work-weary plumbers, truck-drivers, longshoremen, bogus dentists, dubious preachers, cashiered school superintendents. Now and then a quack of some other school — say homeopathy — plunges into it. Hundreds of promising students come from the intellectual ranks of hospital orderlies.
…[The chiropractor’s] trade is mainly with ambulant patients; they must come to his studio for treatment. Most of them have lingering diseases; they tour all the neighborhood doctors before they reach him. His treatment, being nonsensical, is in accord with the divine plan. It is seldom, perhaps, that he actually kills a patient, but at all events he keeps any a worthy soul from getting well.
…But chiropractic, of course, is not perfect. It has superb potentialities, but only too often they are not converted into concrete cadavers. The hygienists rescue many of its foreordained customers, and, turning them over to agents of the Medical Trust, maintained at the public expense, get them cured. Moreover, chiropractic itself is not certainly fatal: even an Iowan with diabetes may survive its embraces. Yet worse, I have a suspicion that it sometimes actually cures. For all I know (or any orthodox pathologist seems to know) it may be true that certain malaises are caused by the pressure of vagrant vertebra upon the spinal nerves. And it may be true that a hearty ex-boilermaker, by a vigorous yanking and kneading, may be able to relieve that pressure. What is needed is a scientific inquiry into the matter, under rigid test conditions, by a committee of men learned in the architecture and plumbing of the body, and of a high and incorruptible sagacity. Let a thousand patients be selected, let a gang of selected chiropractors examine their backbones and determine what is the matter with them, and then let these diagnoses be checked up by the exact methods of scientific medicine. Then let the same chiropractors essay to cure the patients whose maladies have been determined. My guess is that the chiropractors’ errors in diagnosis will run to at least 95% and that their failures in treatment will push 99%. But I am willing to be convinced.
Where is there is such a committee to be found? I undertake to nominate it at ten minutes’ notice. The land swarms with men competent in anatomy and pathology, and yet not engaged as doctors. There are thousands of hospitals, with endless clinical material. I offer to supply the committee with cigars and music during the test. I offer, further, to supply both the committee and the chiropractors with sound wet goods. I offer, finally, to give a bawdy banquet to the whole Medical Trust at the conclusion of the proceedings.
I imagine that most chiropractors would find this comment rather disturbing. However, I do like it for several reasons:
- it is refreshingly politically incorrect; today journalists seem to be obsessed with the notion of ‘balance’ thus often creating the impression that there are two valid sides to an issue where, in fact, there is only one;
- it gets right at the heart of several problems which have plagued chiropractic from its beginning;
- it even suggests a way to establishing the truth about the value of chiropractic which could easily been followed some 90 years ago;
- finally it predicts a result of such a test – and I would not be surprised, if it turned out to be not far from the truth.
Please let me know what you think, regardless of whether you are a chiropractor or not.
Chapter 5 of my memoir is entitled ‘OFF WITH HIS HEAD’. It describes the role that Prince Charles played in promoting what he now likes to call ‘integrated medicine’. The weird thing is that he was instrumental in creating my Exeter chair…and eventually in getting it shut down. Here is a short sample to whet your appetite:
With the wisdom of hindsight, it is clear to me now that my hope of bringing the scientific method to bear on alternative medicine was doomed from the start. Reason cannot negotiate with unreason any more than fire and water can commingle peacefully. In either case, a great deal of spitting and hissing is bound to ensue—and precious little else.
Soon after arriving in Exeter, in 1993, I learnt of the long-standing interest Prince Charles had in alternative medicine: he had asked via my Vice Chancellor for a copy of my inaugural lecture, and I remember being delighted at this request. As I never give lectures or speeches from a script, I even composed a summary specifically for him. In return, I received a polite note of thanks from one of his secretaries. This is great, I thought.
I was thrilled that someone as influential as Prince Charles would be interested in my work. What could be better than having support in such high places? Surely, there would come the time when I could meet the Prince and have an open exchange of views. I had no doubt that he would be keenly aware of the obvious necessity for rigorous research—in fact, he often enough had publicly stressed it—and would thus support my research endeavours.
How wrong can one be? Prince Charles turned out to be no supporter of my work. To the contrary: he seemed to be a staunch advocate of unreason and a formidable opponent of any attempt to bring science or critical thinking to bear on alter-native medicine. What is more, subsequent events suggested to me that his intervention played a part in the closure of my unit.
Chinese proprietary herbal medicines (CPHMs) are a well-established and a hugely profitable part of Traditional Chinese Medicine (TCM) with a long history in China and elsewhere; they are used for all sorts of conditions, not least for the treatment of common cold. Many CPHMs have been listed in the ‘China national essential drug list’ (CNEDL), the official reference published by the Chinese Ministry of Health. One would hope that such a document to be based on reliable evidence – but is it?
The aim of a recent review was to provide an assessment on the potential benefits and harms of CPHMs for common cold listed in the CNEDL.
The authors of this assessment were experts from the Chinese ‘Centre for Evidence-Based Medicine’ and one well-known researcher of alternative medicine from the UK. They searched CENTRAL, MEDLINE, EMBASE, SinoMed, CNKI, VIP, China Important Conference Papers Database, China Dissertation Database, and online clinical trial registry websites from their inception to 31 March 2013 for clinical studies of CPHMs listed in the CNEDL for common cold.
Of the 33 CPHMs listed in the 2012 CNEDL for the treatment of common cold, only 7 had any type of clinical trial evidence at all. A total of 6 randomised controlled trials (RCTs) and 7 case series (CSs) could be included in the assessments.
All these studies had been conducted in China and published in Chinese. All of them were burdened with poor study design and low methodological quality, and all had to be graded as being associated with a very high risk of bias.
The authors concluded that the use of CPHMs for common cold is not supported by robust evidence. Further rigorous well designed placebo-controlled, randomized trials are needed to substantiate the clinical claims made for CPHMs.
I should state that it is, in my view, most laudable that the authors draw such a relatively clear, negative conclusion. This does certainly not happen often with papers originating from China, and George Lewith, the UK collaborator in this article, is also not known for his critical attitude towards alternative medicine. But there are other, less encouraging issues here to mention.
In the discussion section of their paper, the authors mention that the CNEDL has been approved by the Chinese Ministry of Public Health and is currently regarded as the accepted reference point for the medicines used in China. They also explain that the CNEDL was officially launched and implemented in August 2009. The CNEDL is now up-dated every 3 years, and its 2012 edition contains 520 medicines, including 203 CPHMs. The CPHMs listed in CNEDL cover 137 herbal remedies for internal medicine, 11 for surgery, 20 for gynaecology, 7 for ophthalmology, 13 for otorhinolaryngology and 15 for orthopaedics and traumatology.
Moreover, the authors inform us that about 3,100 medical and clinical experts had been recruited to evaluate the safety, effectiveness and costs of CPHMs. The selection process of medicines into CNEDL was strictly in accordance with the principle that they ‘must be preventive and curative, safe and effective, affordable, easy to use, think highly of both Chinese and Western medicine’. A detailed procedure for evaluation is, however, not available because the files are confidential.
The authors finally state that their paper demonstrates that the selection of CPHMs into the CNEDL is less likely to be ‘evidence-based’ and revealed the sharp contrast between the policy and priority given to by the Chinese government to Traditional Chinese Medicine(TCM).
This surely must be a benign judgement, if there ever was one! I would say that the facts disclosed in this review show that TCM seems to exist in a strange universe where commercial interests are officially allowed to reign supreme over patients’ interests and public health.
Neck pain is a common problem which often causes significant disability. Chiropractic manipulation has become one of the most popular forms of alternative treatment for such symptoms. This seems surprising considering that neck manipulations are neither convincingly effective nor free of adverse effects.
The current Cochrane review on this subject could not be clearer: “Done alone, manipulation and/or mobilization were not beneficial; when compared to one another, neither was superior.” In the absence of compelling evidence for efficacy, any risk of neck manipulation would tilt the risk/benefit balance into the negative.
Adverse effects of neck manipulations range from mild symptoms, such as local neck tenderness or stiffness, to more severe injuries involving the spinal cord, peripheral nerve roots, and arteries within the neck. A recent paper reminds us that another serious complication has to be added to this already long list: phrenic nerve injury.
The phrenic nerve is responsible for controlling the contractions of the diaphragm, which allows the lungs to take in and release air and make us breathe properly. The phrenic nerve is formed from C3, C4, and C5 nerve fibres and descends along the anterior surface of the scalenus anterior muscle before entering the thorax to supply motor and sensory input to the diaphragm. Its anatomic location in the neck leaves it vulnerable to traumatic injury. Phrenic nerve injury can result in paralysis of the diaphragm and often leads to deteriorating function of the diaphragm, which can lead to partial or complete paralysis of the muscle and, as a result, serious breathing problems.
Patients who experience such problems may require emergency medical treatment or surgery. Sudden, severe damage to the phrenic nerve can make it impossible for the diaphragm to contract on its own. In order to make sure that the patient can breathe, a breathing tube needs to be inserted, a process called intubation. Artificial respiration would then be required.
American neurologists published a case report of a healthy man who consulted a chiropractor for his neck pain. Predictably, the chiropractor employed cervical manipulation to treat this condition. The result was bilateral diaphragmatic paralysis.
Similar cases have been reported previously, for instance, here and here and here and here. Damage to other nerves has also been documented to be a possible complication of spinal manipulation, for instance, here and here.
The authors of this new case report conclude that physicians must be aware of this complication and should be cautious when recommending spinal manipulation for the treatment of neck pain, especially in the presence of preexisting degenerative disease of the cervical spine.
I know what my chiropractic friends will respond to this post:
- I am alarmist,
- I cherry-pick articles that are negative for their profession,
- these cases are extreme rarities,
- conventional medicine is much more dangerous.
To this I reply: Imagine a conventional therapy about which the current Cochrane review says that it has no proven effect for the condition in question. Imagine further that this therapy causes mild to moderate adverse effects in about 50% of all patients in addition to very dramatic complications which are probably rare but, as no monitoring system exists, of unknown frequency. Imagine now that the professionals using this treatment more regularly than any other clinicians steadfastly deny that the risk/benefit balance is way out of kilter.
Would you call someone who repeatedly tries to warn the public of this situation ‘alarmist’?
Would you not consider the professionals who continue to practice the therapy in question to be irresponsible?
A recent article from THE CHIROPRACTIC REPORT entitled ‘Media Criticism – Whether and How to Respond’ has caught my attention. It provides detailed and, in my view, quite remarkable advice to chiropractors as to how they should react to criticism. Here is an excerpt:
…the easiest media comment to challenge is one that makes an absolute claim – for example Salzberg’s claim that the practice of chiropractic is “highly dubious.” It also means that an effective response should usually not be absolute – claiming for example that chiropractic care can cure, or a specific chiropractic treatment is proven effective for, a specific condition.
Let’s explore this with an example. In 2008 a British journalist, Simon Singh, while promoting a new book he had co-authored that was heavily critical of chiropractic and complementary and alternative medicine in general, wrote an article in the Guardian newspaper in which he claimed that “there is not a jot of evidence” that chiropractic treatment can help children with “colic, sleeping and feeding problems . . . and prolonged crying.” In other words, a black and white claim.
There was and is evidence. Singh was wrong. How might you respond to this? Here are your options for reply, from the outspoken to the restrained:
a. Chiropractic is proven effective for the cure of infantile colic.
b. Spinal manipulation is proven effective for the cure of infantile colic
c. Manual treatments are proven effective for the cure of infantile colic
d. Chiropractic/spinal manipulation/ manual therapies may be effective in reducing the symptoms of infantile colic.
e. Where spinal joint dysfunction/subluxation is found, chiropractic/spinal manipulation/manual therapies may be effective in reducing abnormal and incessant crying in infants medically diagnosed as having infantile colic
f. Chiropractic care has a central focus of assessing and correcting spinal joint dysfunction/subluxation and its biomechanical and physiological effects, and where these are addressed many symptoms may be reduced including those associated with infantile colic.
The first three options are as black and white as Singh’s statement, and are not supported by the evidence. Some studies say yes, some no. All the other options, which have appropriate qualifiers and shades of gray, are supported by sound evidence.
Much of that evidence is referred to and referenced in the March 2010 issue of this Report, available online at www.chiropracticreport.com/pastissues. To answer Singh effectively one only has to produce some of the good quality research and question how he can be credible when he says “there is not a jot of evidence”.
With respect to evidence, in this context that means evidence published in peer-reviewed scientific journals. You may decide to comment on one or more anecdotal case reports from your practice to give your response greater human interest, but this will mean nothing unless supported by higher levels of published evidence.
Am I the only one to find this remarkable?
Am I wrong in interpreting this as detailed instructions to mislead the public?
Are these instructions not merely advice to defend chiropractic commercial interests at the expense of public health?
How can this be ethical?
How often have we heard it on this blog and elsewhere?
- chiropractic is progressing,
- chiropractors are no longer adhering to their obsolete concepts and bizarre beliefs,
- chiropractic is fast becoming evidence-based,
- subluxation is a thing of the past.
American chiropractors wanted to find out to what extent these assumptions are true and collected data from chiropractic students enrolled in colleges throughout North America. The stated purpose of their study is to investigate North American chiropractic students’ opinions concerning professional identity, role and future.
A 23-item cross-sectional electronic questionnaire was developed. A total of 7,455 chiropractic students from 12 North American English-speaking chiropractic colleges were invited to complete the survey. Survey items encompassed demographics, evidence-based practice, chiropractic identity and setting, and scope of practice. Data were collected and descriptive statistical analyses were performed.
A total of 1,243 questionnaires were electronically submitted. This means the response rate was 16.7%. Most respondents agreed (34.8%) or strongly agreed (52.2%) that it is important for chiropractors to be educated in evidence-based practice. A majority agreed (35.6%) or strongly agreed (25.8%) the emphasis of chiropractic intervention is to eliminate vertebral subluxations/vertebral subluxation complexes. A large number of respondents (55.2%) were not in favor of expanding the scope of the chiropractic profession to include prescribing medications with appropriate advanced training. Most respondents estimated that chiropractors should be considered mainstream health care practitioners (69.1%). About half of all respondents (46.8%) felt that chiropractic research should focus on the physiological mechanisms of chiropractic adjustments.
The authors of this paper concluded that the chiropractic students in this study showed a preference for participating in mainstream health care, report an exposure to evidence-based practice, and desire to hold to traditional chiropractic theories and practices. The majority of students would like to see an emphasis on correction of vertebral subluxation, while a larger percent found it is important to learn about evidence-based practice. These two key points may seem contradictory, suggesting cognitive dissonance. Or perhaps some students want to hold on to traditional theory (e.g., subluxation-centered practice) while recognizing the need for further research to fully explore these theories. Further research on this topic is needed.
What should we make of these findings? The answer clearly must be NOT A LOT.
- the response rate was dismal,
- the questionnaire was not validated
- there seems to be little critical evaluation or discussion of the findings.
If anything, these findings seem to suggest that chiropractors want to join evidence based medicine, but on their own terms and without giving up their bogus beliefs, concept and practices. They seem to want the cake and eat it, in other words. The almost inevitable result of such a development would be that real medicine becomes diluted with quackery.
