It has been reported that Karnataka’s Deputy Chief Minister, Dr CN Ashwathnarayan, has launched eight products, several of which fall in the category of so-called alternative medicine (SCAM), aimed at mitigating COVID-19, developed by various start-ups at Bangalore Bioinnovation Centre (BBC). Dr CN Ashwathnarayan said the launch of the products shows that Karnataka has emerged as a leading state in developing solutions to fight the COVID 19 pandemic.

Here are short descriptions of the innovations:

  • Padma Vitals +: Developed by Innovator start-up Dr. Madan Gopal of Cardiac Design labs,Padma Vitals + is a  centralized monitoring system for ECG, respiration, Spo2 and body temperature, which can measure the vitals continuously and the analysis sent through telemetry, with an alerting system embedded in it. The device is much needed for contactless monitoring of patients during COVID 19 Pandemic. The product has been validated at Narayana Hrudayalaya.
  • Malli’s Cordytea: Developed by Dr. Moushmi Mondal from Mallipatra Neutraceuticals, this product is an Immunity booster tea prepared from medicinal mushroom – Cordyceps. The mushroom variety grown under laboratory conditions is developed by the Innovator. Cordicepin, an active ingredient is known to have anti-viral properties too. In the COVID 19 times, it will be helpful in boosting the immunity levels. The product has been patented and is approved by FSSAI.
  • CD4 Shield : Developed by Dr. Vijay Lanka and his team from Stabicon, this product is a chewable tablet containing curcumin and Vitamin B12. Both the ingredients fight inflammation and infection. The product ensures activation of innate immunity by activating CD4+, CD8+ and IFN 1 to virus specific effect and has immunomodulatory properties. It also reduces cytokine storm in response to viral infection. The product is approved by FSSAI.
  • BeamRoti : Developed by Dr. Srinivas from Aspartika, the product is an immunity booster chapati having mixture of herbs recommended by AYUSH ministry. The ingredients have been prepared using supercritical fluid extraction technology to ensure optimum concentration of herbal extract reaches the body. The chapatis are easy to store with good shelf life and Patent application has been filed. The product is approved by FSSAI.
  • Immune booster daily drops: Developed by Dr. Srinivas from Aspartika, the product is an immunity booster drop having mixture of herbs recommended by AYUSH ministry. The ingredients have been prepared using supercritical fluid extraction technology to ensure optimum concentration of herbal extract reaches the body by mixing just one drop of the product in a glass of hot water. The product is approved by FSSAI.
  • VegPhal – Fruit and Vegetable Sanitizer: Developed by Deepak Bhajantri from Krimmi Biotech, this fruit and vegetable sanitizer is prepared using edible ingredients effective against microbes and removal of pesticides. It is chorine and alcohol free.
  • Water Sanitizer – Kitchen Tap: The product is developed by Ravi Kumar from Biofi and is a miniaturized version of UV purifier that can be attached to a water tap and kill 99% of microbes including viruses such as phages.
  • nti-Micobial HVAC module: The product is developed by Ravi Kumar from Biofi and is a module that can be fitted to HVAC system to ensure circulating air is sanitized. This is especially useful during COVID 19 times as many enclosed spaces in which AC circulated air may be contaminated. Based on UV-silver titanium dioxide technology, the product is patented and has been validated.

Karnataka is of course a state in the south western region of India. The region has so far about one million COVID-19 cases, while almost 12 000 people have died. One would therefore very much hope that the newly launched innovations can make a difference.

But will they?

As far as the SCAM-related products (e.g. ‘immune boosters’) are concerned, I see no convincing evidence to assume that they are effective. If anyone has information to the contrary, please let me know.

But why not? They can’t do any harm!

Sadly, I am am not so sure. I see the potential for considerable harm from all the useless SCAMs that are being promoted left right and centre for protecting the public against COVID-19. Firstly, there is the financial harm of paying for products that are useless. Secondly, ineffective effords might distract from finding and adhering to efforts that are effective. Thirdly, believing in a SCAM that does not work will create a sense of false security which, in turn, renders consumers more vulnerable to catch the virus.

As always in healthcare, even harmless interventions that do not work can become dangerous, as they lead to neglecting effective measures. I shudder to think of how many deaths have been caused by the many SCAM merchants who see the current pandemic as an opportunity.

Numerous so-called alternative medicines (SCAMs) have been touted as the solution for COVID-19. In fact, it is hard to find a SCAM that is not claimed to be useful for corona patients. Crucially, such claims are being made in the complete absence of evidence. A recent paper offers a bibliometric analysis of global research trends at the intersection of SCAM and COVID-19.

SCOPUS, MEDLINE, EMBASE, AMED and PSYCINFO databases were searched on July 5, 2020. All publication types were included, however, articles were only deemed eligible, if they made mention of one or more SCAMs for the potential prevention, treatment, and/or management of COVID-19 or a health issue indirectly resulting from the COVID-19 pandemic. The following eligible article characteristics were extracted: title; author names, affiliations, and countries; DOI; publication language; publication type; publication year; journal (and whether it is TICAM-focused); 2019 impact factor, and TICAMs mentioned.

A total of 296 eligible articles were published by 1373 unique authors at 977 affiliations across 56 countries. The most common countries associated with author affiliation included:

  • China,
  • the United States,
  • India,
  • Italy.

Four journals had published more that 10 papers each on the subject:

  • Chinese Traditional and Herbal Drugs,
  • Journal of Biomolecular Structure & Dynamics,
  • Zhongguo Zhongyao Zazhi (China Journal of Chinese Materia Medica),
  • Pharmacological Research

The vast majority of articles were published in English, followed by Chinese. Eligible articles were published across 157 journals, of which 33 were SCAM-focused; a total of 120 journals had a 2019 impact factor, which ranged from 0.17 to 60.392. A total of 327 different SCAMs were mentioned across eligible articles, with the most common ones including:

  • traditional Chinese medicine (n = 94),
  • vitamin D (n = 67),
  • melatonin (n = 16),
  • phytochemicals (n = 12),
  • general herbal medicine (n = 11).

The Canadian author concluded that this study provides researchers and clinicians with a greater knowledge of the characteristics of articles that been published globally at the intersection of COVID-19 and SCAM to date. At a time where safe and effective vaccines and medicines for the prevention and treatment of COVID-19 have yet to be discovered, this study provides a current snapshot of the quantity and characteristics of articles written at the intersection of SCAM therapies and COVID-19.

If anyone repeated the research today, I fear that the number of different SCAMs would have at least doubled. There is simply no form of SCAM that would not have joined the bandwagon of snake-oil salesmen trying to make a quick buck or satisfying their dangerous delusion of a panacea. Today (11/12/2020) my very quick Medline search on just a few SCAMs resulted in the following:

  • Herbal medicine: 253
  • Dietary supplement: 139
  • Acupuncture: 68
  • Homeopathy (not mentioned at all above): 20
  • Chiropractic: 13
  • Naturopathy: 6

One of the most chilling reads during my ‘rough and ready’ trawl through the literature was an article co-authored by a Viennese professor who has featured repeatedly on this blog. Here is its abstract:

Successful homeopathic prescriptions are based on careful individualization of symptoms, either for an individual patient or collectively in the case of epidemic outbreaks. The ongoing COVID-19 pandemic was initially represented as a severe acute respiratory illness, with eventual dramatic complications. However, over time it revealed to be a complex systemic disease with manifestations derived from viral-induced inflammation and hypercoagulability, thus liable to affect any body organ or system. As a result, clinical presentation is variable, in addition to variations associated with several individual and collective risk factors. Given the extreme variability of pathology and clinical manifestations, a single, or a few, universal homeopathic preventive Do not split medicine(s) do not seem feasible. Yet homeopathy may have a relevant role to play, inasmuch as the vast majority of patients only exhibit the mild form of disease and are indicated to self-care at home, without standard monitoring, follow-up, or treatment. For future pandemics, homeopathy agencies should prepare by establishing rapid-response teams and efficacious lines of communication.

The Canadian author of the above paper did not analyse how many of the papers he included would make therapeutic claims. I suspect that the majority did. In this context, one of the clearest indications of how deluded SCAM practitioners tend to be during these difficult times was provided by this paper:

Coronavirus disease 2019 (COVID-19), caused by a new coronavirus, first appeared in late 2019. What initially seemed to be a mild influenza quickly revealed itself as a serious and highly contagious disease, and the planet was soon faced with a significant morbidity and mortality associated with this pathogen. For homeopathy, shunned during its 200 years of existence by conventional medicine, this outbreak is a key opportunity to show potentially the contribution it can make in treating COVID-19 patients. This should be done through performance of impeccably controlled, prospective, randomized clinical trials, with publication of their findings in well-ranked conventional medicine journals. If the homeopathy community fails to take advantage of this rare opportunity, it might wait another century for the next major pandemic.

I must admit, I felt vaguely sick while reading it.

I was alerted to an interview published in an anthroposophical journal with Prof. Dr. med. Harald Matthes. He is the clinical director of the ‘Gemeinschaftskrankenhauses Havelhöhe‘, a hospital of anthroposophic medicine in Berlin where apparently some COVID-19 patients are presently being treated. Anthroposophic medicine is a medical cult created by the mystic, Rudolf Steiner, about 100 years ago that lacks a basis in science, facts or common sense. Here is the two passages from that interview that I find most interesting (my translation/explanation is below):

Es gibt bisher kein spezifisches Covid-19 Medikament aus der konventionellen Medizin. Remdesivir führt in Studien zu keinem signifikant verbesserten Überleben, sondern lediglich zu einer milden Symptomreduktion. Die anfänglich große Studie vor allem an Universitätskliniken mit Hydrochloroquin und Azithromycin erbrachte sogar eine Steigerung der Todesrate. Daher haben anthroposophische Therapiekonzepte mit Steigerung der Selbstheilungskräfte eine große Bedeutung erfahren. Wichtige anthroposophische Arzneimittel waren dabei das Eisen als Meteoreisen oder als Ferrum metallicum praep., der Phosphor, das Stibium sowie das Cardiodoron® und Pneumodoron®, aber auch Bryonia (Zaunrübe) und Tartarus stibiatus (Brechweinstein). Die Erfolge waren sehr gut, da in Havelhöhe bisher kein Covid-19 Patient verstorben ist, bei einer sonstigen Sterblichkeit von ca. 30% aller Covid-19-Intensivpatienten…

100 Jahre Bazillentheorie und die Dominanz eines pathogenetischen Medizinkonzeptes haben zu der von Rudolf Steiner bereits 1909 vorausgesagten Tyrannei im Sozialen geführt. Der Mensch hat ein Mikrobiom und Virom, das unverzichtbar für seine Immunität ist und von der Quantität mächtiger als der Mensch selbst (Mikrobiom 1014 Bakterien mit ca. 1200 Spezies z.B. im Darm bei nur 1012 Körperzellen).

Matthes explains that, so far, no medication has been demonstrated to be effective against COVID-19 infections. Then he continues: “This is the reason why anthroposophic therapies which increase the self-healing powers have gained great importance”, and names the treatments used in his hospital:

  • Meteoric Iron (a highly diluted anthroposophic remedy based on iron from meteors),
  • Ferrum metallicum praep. (a homeopathic/anthroposophic remedy based on iron),
  • Phosphor (a homeopathic remedy based on phosphor),
  • Stibium (a homeopathic remedy based on antimony),
  • Cardiodoron (a herbal mixture used in anthroposophical medicine),
  • Pneumodoron (a herbal mixture used in anthroposophical medicine containing).

Matthes also affirms (my translation):

“The success has so far been very good, since no COVID-19-patient has died in Havelhöhe – with a normal mortality of about 30% of COID_19 patients in intensive care…

100 years of germ theory and the dominance of a pathogenetic concept of medicine have led to the tyranny in the social sphere predicted by Rudolf Steiner as early as 1909. Humans have a microbiome and virom that is indispensable for their immunity and more powerful in quantity than humans themselves (microbiome 1014 bacteria with about 1200 species e.g. in the intestine with only 1012 somatic cells)…”

_________________

The first 4 remedies listed above are highly diluted and contain no active molecules. The last two are less diluted and might therefore contain a few active molecules but in sub-therapeutic doses. Crucially, none of the remedies have been shown to be effective for any condition.

The germ theory of disease which Matthes mentions is, of course, a bit more than a ‘theory’; it is the accepted scientific explanation for many diseases, including COVID-19.

I have cold sweats when I think of anthroposophical doctors who seem to take it less than seriously, while treating desperately ill COVID-19 patients. If I were allowed to ask just three questions to Matthes, I think, it would be these:

  1. How did you obtain fully informed consent from your patients, including the fact that your remedies are unproven and implausible?
  2. If you think your results are so good, are you monitoring them closely to publish them urgently, so that other centres might learn from them?
  3. Do you feel it is ethical to promote unprovn treatments during a health crisis via a publicly available interview before your results have been formally assessed and published?

Recent comments on this blog prompted me to look into a very strange therapeutic and diagnostic device used by some practitioners of so-called alternative medicine (SCAM):

The OBERON provides the most unique tool for scanning the various organs and systems of the physical body without having to make a medical or surgical intrusion. Developed by Russian scientists since the early 1990’s, the OBERON is the most revolutionary computer programmed invention available in the world today for analyzing and treating all the body’s organs and functions.

This device scans each organ or tissue on a cellular level. It compares the measurements to a database of thousands of referenced conditions and their diagnosis. OBERON uses a special emitter to modulate the carrier frequency for the cell communication and it uses special sensor trigger readers built into headphones to read the cells own signals.

OBERON finds out how stressed an organ is, and if there are any diseases developing, how much the cells are influenced by a specific disease, and which micro organisms and bacteria are in the area at the time of the scan.

BENEFITS OF THE OBERON:
 Rebalances the body so that it can start to heal itself!
 Makes intrusive and embarrassing examinations a THING OF THE PAST!!!!
 Quick examination (in seconds) with immediate results
 Replaces dozens of traditional diagnostic methods.
 Finds weaknesses in the skeleton, organs, blood, tissue, etc.
 There are no side effects, unpleasantness or injury after treatment
 Bio-resonance META-therapy
 A print out of the report on findings can be taken at the end of the session…

The method is based on an analysis of the brain stems electromagnetic waves which contain the complete information of the entire organism. This information is read by a sensor. A frequency transmitter aimed at the projection area of the brain stem stimulates this electromagnetic radiation.

Meta- Therapy repairs the organism using a diversity of modulated electromagnetic waves. This treatment stimulates the body’s own functions so that they solve the problem and it stimulates the immune defense and is a very good supplement or alternative to traditional treatment. The patient can follow on the screen how the organ progressively gets better, and afterwards one can take a new measurement showing the improvement…

Sounds fantastic?

Yes, indeed – fantastic as in fantasy!

Almost as much relation to reality as OBERON, king of the fairies in medieval literature.

The modern OBERON device is being used by infamous proponents of integrated medicine like Dr Julian Kenyon who already made an appearance on this blog. On his website, Kenyon published a paper in which he provides details about the OBERON. To a lay person, the sciency text might look like science; however, this impression would be false. The ‘study’ Kenyon mentioned is not on Medline. In fact, Dr Kenyon (former associate of the late George Lewith) has merely 4 Medline-listed papers:

  1. Physiological and psychological explanations for the mechanism of acupuncture as a treatment for chronic pain. Lewith GT, Kenyon JN.Soc Sci Med. 1984;19(12):1367-78. doi: 10.1016/0277-9536(84)90026-1.PMID: 6085191 Review.
  2. Is electrodermal testing as effective as skin prick tests for diagnosing allergies? A double blind, randomised block design study. Lewith GT, Kenyon JN, Broomfield J, Prescott P, Goddard J, Holgate ST.BMJ. 2001 Jan 20;322(7279):131-4. doi: 10.1136/bmj.322.7279.131.PMID: 11159567 Free PMC article. Clinical Trial.
  3. Randomised double-blind trial on the immediate effects of naloxone on classical Chinese acupuncture therapy for chronic pain. Kenyon JN, Knight CJ, Wells C. Acupunct Electrother Res. 1983;8(1):17-24. doi: 10.3727/036012983816715064.PMID: 6135300 Clinical Trial.
  4. Food sensitivity, a search for underlying causes. Case study of 12 patients. Kenyon JN.Acupunct Electrother Res. 1986;11(1):1-13. doi: 10.3727/036012986816359238.PMID: 2872775

And what about other researchers? Aren’t there ANY decent studies of the OBERON?

Not as far as I can see (if anyone does know of peer-reviewed research, please let me know).

So, what is the conclusion?

My conclusion is this:

There is no evidence that the OBERON does anything useful other than putting money in the bank accounts of those charlatans who use or manufacture it.

And what does that make Kenyon and all the other SCAM practitioners using the OBERON or similar devices?

I leave it to you to decide.

 

Misinformation by chiropractors is unfortunately nothing new and has been discussed ad nauseam on this blog. It is tempting to ask whether chiropractors have lost (or more likely never had) the ability to ditinguish real information from misinformation or substantiated from unsubstantiated claims. During the pandemic, the phenomenon of chiropractic misinformation has become even more embarrassingly obvious, as this new article highlights.

Chiropractors made statements on social media claiming that chiropractic treatment can prevent or impact COVID-19. The rationale for these claims is that spinal manipulation can impact the nervous system and thus improve immunity. These beliefs often stem from nineteenth-century chiropractic concepts. The authors of the paper are aware of no clinically relevant scientific evidence to support such statements.

The investigators explored the internet and social media to collect examples of misinformation from Europe, North America, Australia and New Zealand regarding the impact of chiropractic treatment on immune function. They discussed the potential harm resulting from these claims and explore the role of chiropractors, teaching institutions, accrediting agencies, and legislative bodies.

The authors conclude as follows: In this search of public media in Europe, North America, New Zealand, and Australia, we discovered many cases of misinformation. Claims of chiropractic treatment improving immunity conflict with the advice from authorities and the scientific consensus. The science referenced by these claims is missing, flawed or has no clinical relevance. Consequently, their claims about clinical effectiveness are spurious at best and misleading at worst. However, our examples cannot be used to make statements about the magnitude of the problem among practitioners as our samples were not intended to be representative. For that reason, we also did not include an analysis of the arguments provided in the various postings. In view of the seriousness of the topic, it would be relevant to conduct a systematic study on a representative sample of public statements, to better understand these issues. Our search illustrates the possible danger to public health of misinformation posted on social media and the internet. This situation provides an opportunity for growth and maturation for the chiropractic profession. We hope that individual chiropractors will reflect on and improve their communication and practices. Further, we hope that the chiropractic teaching institutions, regulators, and professional organisations will always demonstrate responsible leadership in their respective domains by acting to ensure that all chiropractors understand and uphold their fiduciary duties.

Several previous papers have found similar things, e.g.: Twitter activity about SMT and immunity increased during the COVID-19 crisis. Results from this work have the potential to help policy makers and others understand the impact of SMT misinformation and devise strategies to mitigate its impact.

The pandemic has crystallised the embarrassment about chiropractic false claims. Yet, the phenomenon of chiropractors misleading the public has long been known and arguably is even more important when it relates to matters other than COVID-19. Ten years ago, we published this paper:

Background: Some chiropractors and their associations claim that chiropractic is effective for conditions that lack sound supporting evidence or scientific rationale. This study therefore sought to determine the frequency of World Wide Web claims of chiropractors and their associations to treat, asthma, headache/migraine, infant colic, colic, ear infection/earache/otitis media, neck pain, whiplash (not supported by sound evidence), and lower back pain (supported by some evidence).

Methods: A review of 200 chiropractor websites and 9 chiropractic associations’ World Wide Web claims in Australia, Canada, New Zealand, the United Kingdom, and the United States was conducted between 1 October 2008 and 26 November 2008. The outcome measure was claims (either direct or indirect) regarding the eight reviewed conditions, made in the context of chiropractic treatment.

Results: We found evidence that 190 (95%) chiropractor websites made unsubstantiated claims regarding at least one of the conditions. When colic and infant colic data were collapsed into one heading, there was evidence that 76 (38%) chiropractor websites made unsubstantiated claims about all the conditions not supported by sound evidence. Fifty-six (28%) websites and 4 of the 9 (44%) associations made claims about lower back pain, whereas 179 (90%) websites and all 9 associations made unsubstantiated claims about headache/migraine. Unsubstantiated claims were made about asthma, ear infection/earache/otitis media, neck pain,

Conclusions: The majority of chiropractors and their associations in the English-speaking world seem to make therapeutic claims that are not supported by sound evidence, whilst only 28% of chiropractor websites promote lower back pain, which is supported by some evidence. We suggest the ubiquity of the unsubstantiated claims constitutes an ethical and public health issue.

It makes it clear that the misleading information of chiropractors is a serious problem. And I find it disappointing to see that so little has been done about it, and that progress seems so ellusive.

This, of course, begs the question, where does all this misinformation come from? The authors of the new paper stated that beliefs often stem from nineteenth-century chiropractic concepts. This, I believe, is very true and it gives us an important clue. It suggests that, because it is good for business, chiro schools are still steeped in obsolete notions of pseudo- and anti-science. Thus, year after year, they seem to churn out new generations of naively willing victims of the Dunning Kruger effect.

We have often heard it said on this blog and elsewhere that chiropractors are making great strides towards reforming themselves and becoming an evidence-based profession. In view of the data cited above, this does not ring all that true, I am afraid. Is the picture that emerges not one of a profession deeply embroiled in BS with but a few fighting a lost battle to clean up the act?

One of my last posts re-ignited the discussion about the elementary issue of informed consent, specifically about informed consent for chiropractors. As it was repeatedly claimed that, in Australia, informed consent is a legal requirement for all chiros, I asked on Wednesday 11 November 2020 at 07:12

FOUR QUESTIONS TO DC + CRITICAL CHIRO (CC):

1) what does the law say about informed consent for Australian chiros?
2) what info exactly do you have to provide?
3) who monitors it?
4) what published evidence do we have about compliance?

CC then posted this reply:

Here we go again you demand evidence while providing little if any for your own assumptions (poor case studies do not count. The pleural of anecdote does not equal evidence whether it’s from chiro’s or you).
We have been over this many times over many years, I cite research/provide links yet you still find it challenging to take it onboard. It is human nature to feel obligated once making a public statement to defend it no matter how much evidence is sent your way. So not surprising.

“1) what does the law say about informed consent for Australian chiros?”
It is all freely available on the national regulators website (as you know and as I have referenced in the past):
https://www.chiropracticboard.gov.au/Codes-guidelines/Code-of-conduct.aspx
https://www.chiropracticboard.gov.au/Search.aspx?q=Informed+consent
Some research by chiropractors on this topic (cited many times in the past):
Risk Management for Chiropractors and Osteopaths. Informed consent
A Common Law Requirement (2004):
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2051308/
Quick advanced PubMed with filters set to “Chiropractic” AND “Informed consent”.
https://www.ncbi.nlm.nih.gov/pmc/?term=(Chiropractic)+AND+Informed+consent
Not rocket science
Latest paper that you wrote an ill informed blog on and the comments were not going as you expected (So I expected you to double down like Donald Trump with a new blog within days. Your getting predictable).
https://chiromt.biomedcentral.com/articles/10.1186/s12998-020-00342-5
This paper questions the legal implications of vertebral subluxations with high powered legal input and is a broadside by evidence based chiropractors against vitalistic chiropractors. You respond a snide fantasy informed consent dialogue when you should be supporting the authors:
https://edzardernst.com/2020/11/informed-consent-why-chiropractors-dont-like-it/

“2) what info exactly do you have to provide?”
“4) what published evidence do we have about compliance?”
We have discussed this as well. It is a common law requirement for every profession and is checked upon re-registration by AHPRA every year and by the professional indemnity insurers every year. No informed consent, no registration and no professional indemnity insurance.
Checked AHPRA’s panel decisions and went back 5 YEARS and found ONE decision relating to informed consent:
https://www.ahpra.gov.au/Publications/Panel-decisions.aspx

“3) who monitors it?”
Another of your tired old arguments that we have discussed many times over the years.
In the UK there is the “‘Chiropractic Reporting and Learning System’ (CRLS)” but this is set up by the association representing chiropractors and not the registration board that advocates for patients. Right idea and step in the right direction, wrong organization.
Here years ago there was a trial of an adverse event reporting system in a Melbourne emergency department systematically collected relevant AE information on all professions which was sent to the relevant board for investigation.
It was supported by doctors and chiropractors while physio’s were not involved. A doctor involved told me it was killed off by ER doctors who “snivelled” about the extra paperwork.
There is no AE reporting system for physio’s, chiro’s, osteo’s, GP’s in private practice etc.
Over the years you have harped on and on about this topic as if it is a failing purely of the chiropractic profession when we have supported initiatives for its implementation.
You have also kept up with the research even commenting on an chiropractic researcher on AE’s Charlotte Leboeuf-Yde (who you highly regard) yet ignored until you could take issue with two sentences written in a blog then you wrote this hatchet blog:
https://edzardernst.com/2017/04/we-have-an-ethical-legal-and-moral-duty-to-discourage-chiropractic-neck-manipulations/
So you are asking for evidence yet willfully ignore an author who “I have always thought highly of Charlotte’s work”.

Stop the cynical cherry picked blogs and start supporting the researchers and reformers otherwise you are just someone standing on the sidelines blindly throwing grenades. You do not care who you hit or the damage you do to the chiropractors leading the reform you demand yet consistently fail to support.

____________________________________

I thought the tone of this response was oddly aggressive and found that CC had failed to understand some of my questions. Yet the link to the chiro’s code of conduct https://www.chiropracticboard.gov.au/Codes-guidelines/Code-of-conduct.aspx was useful. This is what it says about informed consent:

3.5 Informed consent
Informed consent is a person’s voluntary decision about healthcare that is made with knowledge and understanding of the benefits and risks involved. A useful guide to the information that chiropractors need to give to patients is available in the National Health and Medical Research Council (NHMRC) publication General guidelines for medical practitioners in providing information to patients.3 The NHMRC guidelines cover the information that chiropractors should provide about their proposed management or approach, including the need to provide more information where the risk of harm is greater and likely to be more serious, and advice about how to present information. Good practice involves:
a) providing information to patients in a way they can understand before asking for their consent
b) providing an explanation of the treatment/care recommended, its likely duration, expected benefits and cost, any alternative(s) to the proposed care, their relative risks/benefits, as well as the likely consequences of no care
c) obtaining informed consent or other valid authority before undertaking any examination or investigation, providing treatment/care (this may not be possible in an emergency) or involving patients in teaching or research, including providing information on material risks
 d) consent being freely given, without coercion or pressure
 e) advising patients, when referring a patient for investigation or treatment/ care, that there may be additional costs, which they may wish to clarify before proceeding
 f) obtaining (when working with a patient whose capacity to give consent is or may be impaired or limited) the consent of people with legal authority to act on behalf of the patient, and attempting to obtain the consent of the patient as far as practically possible
 g) being mindful of additional informed consent requirements when supplying or prescribing products not approved or made in Australia, and
h) documenting consent appropriately, including considering the need for written consent for procedures that may result in serious injury or death.
_______________________________________
This does indeed clarify some of my questions. Related to the fictional patient with neck pain who consults a chiropractor in my previous post, this means the chiro must inform the patient that:
  • the chiro suggests a manipulation of the neck;
  • this often involves forcing a spinal joint beyond its physiological range of motion;
  • the treatment will be short but needs repeating several times during the coming weeks;
  • the expected benefits are a reduction of pain and improvement of motion;
  • the total cost of the treatment series will be xy;
  • there are many other treatment options for neck pain;
  • most of these have a better risk/benefit profile than neck manipulation;
  • having no treatment for neck pain at all is likely to lead to full resolution of the problem over time.

Apart from any doubts that chiropractors would actually comply with these requirements, the question remains: is the listed information sufficient? Does it outline a truly a fully informed consent? I think that essential aspects of informed consent are missing.

  • The code does not explicidly require an explanation about the possible harms of spinal manipulation (i.e. 50% of all patients will suffer mild to moderate adverse effects lasting 2-3 days, and occasionally patients will have a stroke of which some have died).
  • Moreover, the code mentions EXPECTED benefits, but not benefits supported by evidence. Chiros may well EXPECT their treatment to work, but what does the evidence show? As often discussed on this blog, the evidence is negative or very week, depending how you want to interpret it. The code does not require a chiro to inform his patients about this fact.

So, the way I see it, the code does not expressedly demand the chiro to explain his patient that the treatment he is being asked to consent to is

  1. not supported by sound evidence for effectiveness,
  2. nor that the treatment is burdened with significant risks.

And what about the other questions listed above? An Australian chiropractor who will remain anonymous gave me the following answers:

Who monitors Informed Consent?
 
The short answer here is nobody monitors informed consent.  Typically informed consent is a side issue whenever a negligence claim is made.  Similarly, clinical records are a side issue as well.   Thus, when a patient alleges they were injured a complaint is lodged.  As part of the investigation consideration is given regarding the consent process.  If the analysis determines that the adverse outcome was maloccurence rather than negligence  but valid consent was not obtained, the practitioner will still face disciplinary action. 
 
As we are all too well aware, the Boards show little or no desire to be proactive.  I have yet to see any results from the pilot advertising audit project which began approximately 2 years ago.
 
What published evidence have we ab​out compliance?
 
Good question.  To my knowledge Langworthy & Flemming’s 2005 paper is the only one looking at compliance.  Their results suggest that the majority of respondents would be unable to successfully defend a negligence in consent liability charge.  In my experience providing expert opinions in Australian cases, valid consent was not obtained in a single case.  The most bizarre case had the practitioner their expert argue that consent obtained 7 years prior to the injury was still valid.

Yet, Australian chiropractors claim that they abide by the ethical imperative of informed consent. Are they taking the Mickey?

Perhaps not. Perhaps they are merely trying to make sure they do not lose the majority of their clientele. As I already pointed out in my previous post, fully informed consent would make most chiropractic patients turn round and run a mile.

I was alerted to an outstanding article by an unusual author, a law firm, on the subject of chiropractic. Allow me to quote a few passages from it (without changing a word or adding a comment):

When Katie May passed away suddenly from a stroke at just 34 years old, it was initially ruled an accident. After further investigation, a coroner determined the stroke that claimed the model and single mother’s life was caused by injuries sustained during neck manipulation by a chiropractor. And Ms. May is not the first to be affected by this seemingly harmless procedure…

What health issues can be caused by chiropractic manipulation?

Chiropractors typically use their hands to apply pressure to joints, aiming to help alleviate pain and improve body function. This is referred to as a chiropractic adjustment.

Adjustments are commonly performed for neck and/or back pain. Although the Mayo Clinic says the risk of a serious complication is relatively small, these complications can include:

  • A herniated disk, or worsening of an existing herniated disk
  • Compression of nerves in the lower spinal column
  • Stroke, which can result in paralysis or death

The last item on this list is particularly concerning.

Patients who receive neck manipulation are at risk for a stroke caused by vertebral artery dissection. Located in the neck, the vertebral arteries supply blood to the brain and can be torn by stretching and sudden force applied during a neck adjustment.

Studies have shown that vertebral artery dissection occurs in approximately 1 in 100,000 people and can be caused by something as simple as cracking your neck.

How could a chiropractor be responsible for a patient’s injury?

Although the risk of being seriously injured by a chiropractor is low, tragic accidents can and do happen. If you or a loved one believe you have been the victim of medical malpractice, please contact an experienced personal injury attorney.

Explaining how an injury or medical error occurred will help your attorney determine the potential liability of a chiropractor and any other involved parties. A chiropractor’s liability could fall into a legal category such as:

  • Failure to Diagnose a Medical Condition – The chiropractor breaches a duty of care to their patients by failing to diagnose an underlying medical condition. This could occur when a patient reveals or exhibits symptoms of a severe issue, such as a stroke, and is not referred for appropriate medical attention.
  • Lack of Informed Consent – A patient is treated without being properly informed of the potential risks or side effects, and experiences an injury from that treatment.
  • Negligent Manipulation – The patient’s body is adjusted by the chiropractor in such a way that it causes a new injury or worsens an existing injury. This could also include manipulation of a patient who is pregnant and goes into premature labor.
  • Chiropractic Induced Injury – A patient suffers injury, permanent irreversible damage such as paralysis or wrongful death as the direct result of a chiropractic manipulation.

To find out whether or not you may have a case, please discuss your concerns with a qualified personal injury attorney.

What should I do if I think I have been injured by chiropractic manipulation?

A personal injury attorney can help recover compensation for victims of medical malpractice, including those who have experienced a chiropractic injury. Surviving loved ones can also pursue their case after a family member’s wrongful death.

An attorney will help you collect documents, photos and other items pertaining to your case – but staying organized early in the process will be helpful. Try to preserve important documents, such as:

  • Photographs before and after treatment
  • Medical records and medical bills
  • Receipts, appointment confirmations and other paperwork from your chiropractor

There is a time limit to file a medical malpractice lawsuit, referred to as a statute of limitations…

The issue of informed consent has made regular appearances on this blog. It is important and has many intriguing aspects, particularly for so-called alternative medicine (SCAM). On the one hand, it is a ‘conditio sine qua non’ for any form of healthcare, while, on the other hand, it is a near impossibility in SCAM practice.

In this new article published in a chiro-journal, the authors review the origins of informed consent and trace the duty of disclosure and materiality through landmark medical consent cases in four common law (case law) jurisdictions. The duty of disclosure has evolved from a patriarchal exercise to one in which patient autonomy in clinical decision making is paramount. Passing time has seen the duty of disclosure evolve to include non-medical aspects that may influence the delivery of care. The authors argue that a patient cannot provide valid informed consent for the removal of vertebral subluxation. Further, vertebral subluxation care cannot meet code of conduct standards because it lacks an evidence base and is practitioner-centered.

The uptake of the expanded duty of disclosure has been slow and incomplete by practitioners and regulators. The expanded duty of disclosure has implications, both educative and punitive for regulators, chiropractic educators and professional associations. The authors discuss how practitioners and regulators can be informed by other sources such as consumer law. For regulators, reviewing and updating informed consent requirements is required. For practitioners it may necessitate disclosure of health status, conflict of interest when recommending “inhouse” products, recency of training after attending continuing professional development, practice patterns, personal interests and disciplinary findings.

The authors conclude that, ultimately such matters are informed by the deliberations of the courts. It is our opinion that the duty of a mature profession to critically self-evaluate and respond in the best interests of the patient before these matters arrive in court.

In their paper, the authors also provide a standard list of items required for ‘informed’ consent:

(1) emphasizing the patient’s role in shared decision-making

(2) disclosure of information

a. explaining the patient’s medical status including diagnosis and prognosis

b. describing the proposed diagnostic and therapeutic intervention, including the likelihood and effect of associated risks and benefits of the proposed action, including material risks

c. discussing alternatives to the proposed intervention, including doing nothing

(3) prompting and answering patient questions related to the proposed course of action (NB. this involves probing for understanding, not simply asking ‘do you have any questions’), and

(4) eliciting the patient’s preference (usually by signature). (NB. A signed form is not consent. The conversation between the clinician and the patient or carer is the true process of obtaining informed consent. The signature on the consent form is proof that the conversation took place and that the patient understood and agreed.)

The authors of this article – I do commend it to all chiropractors – take a mostly judicial view of informed consent (for an ethical perspective on the subject, I recommend our book). They do not discuss, whether chiropractors do, in fact, adhere to the ethical imperative of informed consent. As I have stated before, there is not much research on this issue. But the little that does exist fails to show that chiropractors care much about it.

But why?

If it’s an ethical imerative, why do chiropractors not abide by it?

The answer to this question is not difficult to find. Just imagine a conversation between a chiropractor (C) and a patient with neck pain (P):

  • P: What’s your diagnisis?
  • C: You are suffering from acute neck pain.
  • P: Thanks, that much was clear to me. What do you suggest I do?
  • C: I will perform a manipulation of your neck, if you agree.
  • P: Why would this help?
  • C: It can realign the vertebrae that are out of place, simply put.
  • P: And my pain will disappear?
  • C: Sometimes it does, yes.
  • P: But will it disappear quicker than without manipulation.
  • C: Some of the evidence says so.
  • P: Ok, but what does the most reliable evidence say?
  • C: It is not entirely clear cut.
  • P: Hmm, that does not sound too good.
  • P: So, tell me, are there any risks?
  • C: About 50% of patients suffer from minor to moderate pain for 2-3 days afterwards.
  • P: That’s a lot!
  • P: Anything else?
  • C: In some cases, neck manipulation was followed by a stroke.
  • P: Gee that’s bad; how often has this happened?
  • C: We know of about 500 such cases.
  • P: Heavens!
  • C: Now, do you want the treatment or not?
  • P: How much will you charge?
  • C: Only 60 Euros per session.
  • P: You mean I have to come back for more, each time risking a stroke?
  • C: Well… You don’t have to.
  • P: Thanks for the info; I am off. Cherio!

I rest my case. 

 

I want to thank our friend ‘OLD BOB’ for alerting me to Patrick Holford’s comment on a recent trial of vitamin C for COVID-19. Here are three short quotes from Holford:

… Overall, 5 out 26 people (19%) died in the vitamin C group while 10 out of 28 (36%) receiving the placebo died. That means that vitamin C almost halved the number of deaths. Those on vitamin C were 60% more likely to survive.

… Of those most critically ill, 4 people (18%) in the vitamin C group died, compared to 10 (50%) in the placebo group. That’s two-thirds less deaths. Statistically this meant that of those most critically ill who were given vitamin C, they were 80% less likely to die…

… now there is another proven treatment – vitamin C…

And here is the abstract of the actual trial Holford refers to:

Background: No specific medication has been proven effective for the treatment of patients with severe coronavirus disease 2019 (COVID-19). Here, we tested whether high-dose vitamin C infusion was effective for severe COVID-19.

Methods: This randomized, controlled, clinical trial was performed at 3 hospitals in Hubei, China. Patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the ICU were randomly assigned in as 1:1 ratio to either the high-dose intravenous vitamin C (HDIVC) or the placebo. HDIVC group received 12 g of vitamin C/50 ml every 12 hours for 7 days at a rate of 12 ml/hour, and the placebo group received bacteriostatic water for injection in the same way. The primary outcome was invasive mechanical ventilation-free days in 28 days(IMVFD28). Secondary outcomes were 28-day mortality, organ failure, and inflammation progression.

Results: Only fifty-six critical COVID-19 patients were ultimately recruited due to the early control of the outbreak. There was no difference in IMVFD28 between two groups. During the 7-day treatment period, patients in the HDIVC group had a steady rise in the PaO2/FiO2 (day 7: 229 vs. 151 mmHg, 95% CI 33 to 122, P=0.01). Patients with SOFA scores ≥3 in the HDIVC group exhibited a trend of reduction in 28-day mortality (P=0.06) in univariate survival analysis. IL-6 in the HDIVC) group was lower than that in the placebo group (19.42 vs. 158.00; 95% CI -301.72 to -29.79; P=0.04) on day 7.

Conclusion: This pilot trial showed that HDIVC might show a potential signal of benefit for critically ill patients with COVID-19, improving oxygenation even though it failed to improve IMVFD28.

The following points are, I think, worth mentioning:

  • This was, according to its authors, a PILOT study.
  • It was far too small (n=56) to provide reliable results on mortality.
  • The trial authors know that and interpret their findings with sufficient caution.
  • The primary endpoint, the IMVFD28, showed NO significant difference between the groups.
  • The secondary endpoint: HDIVC infusion exhibited a non-significant trend of reduction in 28-day mortality (P=0.06).
  • In more severe patients (SOFA score ≥3), univariate survival analysis and Cox regression showed a similar results (P=0.07, HR, 0.32 [95% CI 0.10-1.06]).

And what does all of this mean? It means that, in this pilot study, vitamin C failed to produce a significant result. Only in a subgroup analysis related to a secondary endpoint was there a slight advantage of vitamin C. This effect is, of course, interesting and needs further investigation (I am sure that is happening as we speak). It could have some clinical significance but, just as likely, it could just be due to chance. There is not way of knowing which is which.

In other words, to hype the findings and to even make statements such as ‘now there is another proven treatment, vitamin C’ is not just exaggerated, it is irresponsible.

This begs the question: why does Mr Holford do it? In case you don’t already know about this man, go on the Internet, and you will quickly find possible answers. Here is an excerpt from his Wiki page which might give you a clue:

Patrick Holford is a British author and entrepreneur who endorses a range of controversial vitamin tablets. As an advocate of alternative nutrition and diet methods, he appears regularly on television and radio in the UK and abroad. He has 36 books in print in 29 languages. His business career promotes a wide variety of alternative medical approaches such as orthomolecular medicine, many of which are considered pseudoscientific by mainstream science and medicine.

Holford’s claims about HIV and autism are not in line with modern medical thought, and have been criticised for putting people in danger and damaging public health.

In 2006 Holford was discovered to be using his PR advisor to delete critical content from his Wikipedia page…

Holford has been the subject of criticism for his promotion of medically dubious techniques and products including hair analysis, his support of the now struck off doctor Andrew Wakefield, and advocating the use of “non-drug alternatives for mental health” for which he has been given an award by the Church of Scientology-backed Citizens Commission on Human Rights.

SAY NO MORE!

It is today exactly 8 years that I am writing this blog. To mark the occasion, I am trying to write my shortest post ever. It focusses on a question that has often occupied my mind and rarely leaves the comments sections of this blog: What makes a healthcare professional use a bogus SCAM therapy? Think, for instance, of any practitioner of homeopathy. What makes him or her tick? Why does (s)he practice homeopathy and not real medicine? After years of thinking about it, the answer turns out to be really quite simple. There are only three possibilities:

Practitioners who employ disproven treatments either

try to con you

or

they have been conned themselves

or

both.
