critical thinking

I recently got this comment which might seem reasonable to some readers:

“What is most humorous about the author and this website is how he knocks the hell out of alternative medicine and therapies yet never provides readers with any alternatives, despite claiming to be an expert. For example: it’s like needing new tyres for your car and the salesman keeps on telling you that, I’m sorry this tyre, that tyre, and that tyre is not suitable for your car either. So you ask We’ll what tyre do you recommend then and he says… No comment. Anyone can pick holes in anything that’s easy, but to offer alternatives and provide useful workable information, to complete the equation that’s what is really needed. So all the author is doing is adding negativity and problems to this world without providing any real solutions.”

Reasonable?

Not really!

Why not?

There are several reasons, for instance:

  1. Legitimate criticism is not the same as “knocking the hell” out of something.
  2. Responsible physicians do not offer ‘real solutions’ via the Internet without knowing the full details of the patient they are talking to. In my view, this would not be ethical.

“Yeah, pull the other one!” I hear my opponents mumble. “There must be general solutions to the problems you are discussing on this blog that do not need any knowledge about specific patients!”

Perhaps, let’s see.

Let me go through 5 recent posts and let me try – in deviation from my usual stance – to offer some solutions that are reasonable, ethical and responsible.

  • here I knocked the hell out of Bowen technique advertised for “a wide range of acute and chronic conditions, including back pain, sciatica, neck, shoulder and knee problems, arthritis, asthma, migraine, sports injuries and stress”. My solution: if you suffer from any of these problems, see a good physician, get a proper diagnosis and an evidence-based treatment that fits your special needs.
  • here I knocked the hell out of alternative therapies for chronic pain. My solution: if you suffer from any of these problems, see a good physician, get a proper diagnosis and an evidence-based treatment that fits your special needs.
  • Here I knocked the hell out of homeopathy which allegedly is employed “all over the world [by] doctors, nurses, midwives, vets  and other healthcare professional  who integrate  CAM therapies into their daily  practice because they see effectiveness.” My solution: if you suffer from any of these problems, see a good physician, get a proper diagnosis and an evidence-based treatment that fits your special needs.
  • Here I knocked the hell out of ‘Brain Dust’, an “adaptogenic elixir to maintain healthy systems for superior states of clarity, memory, creativity, alertness and a capacity to handle stress”. My solution: if you suffer from any of these problems, see a good physician, get a proper diagnosis and an evidence-based treatment that fits your special needs.
  • Here I knocked the hell out of homeopathy for allergic rhinitis. My solution: if you suffer allergic rhinitis, see a specialist, get a proper diagnosis and an evidence-based treatment that fits your special needs.

Sorry, am I boring you?

Yes, that’s why I don’t usually offer ‘real solutions’.

I rest my case.

You might think that the question asked in the title of this post is a bit impertinent. Let’s see whether you change your mind after reading on.

“Come along for a ten minute taster sessions and experience the Bowen Technique.
It is appropriate for a wide range of acute and chronic conditions, including back pain, sciatica, neck, shoulder and knee problems, arthritis, asthma, migraine, sports injuries and stress. Ten-minute taster sessions will be offered so that you can experience the therapy first hand. Many find their aches and pains melt away!” 

It is with these exact words that the Royal College of Nursing advertises a session on Bowen Technique to be held during their major conference on Saturday 13 – Wednesday 17 May 2017, Liverpool Arena and Convention Centre.

You may not have heard of the Bowen Technique, one of the more exotic types of alternative medicine. So, let me fill you in:

According to proponents, it is “a system of subtle and precise mobilizations called “Bowen moves” over muscles, tendons, nerves and fascia. The moves are performed using the thumbs and fingers applying only gentle, non invasive pressure. A treatment consists of a series of specific sequences of moves called procedures, with frequent pauses to allow time for the body to respond.”

Wikipedia explains: “recipients are generally fully clothed. Each session typically involves gentle rolling motions along the muscles, tendons, and fascia. The therapy’s distinctive features are the minimal nature of the physical intervention and pauses incorporated in the treatment. Proponents claim these pauses allow the body to “reset” itself. In 2015 the Australian Government’s Department of Health published the results of a review of alternative therapies that sought to determine if any were suitable for being covered by health insurance; Bowen Technique was one of 17 therapies evaluated for which no clear evidence of effectiveness was found.”

Medline lists just one single trial of Bowen Technique; it is not a clinical trial with patients but a study with healthy volunteers; here is its abstract:

The hamstring muscles are regularly implicated in recurrent injuries, movement dysfunction and low back pain. Links between limited flexibility and development of neuromusculoskeletal symptoms are frequently reported. The Bowen Technique is used to treat many conditions including lack of flexibility. The study set out to investigate the effect of the Bowen Technique on hamstring flexibility over time. An assessor-blind, prospective, randomised controlled trial was performed on 120 asymptomatic volunteers. Participants were randomly allocated into a control group or Bowen group. Three flexibility measurements occurred over one week, using an active knee extension test. The intervention group received a single Bowen treatment. A repeated measures univariate analysis of variance, across both groups for the three time periods, revealed significant within-subject and between-subject differences for the Bowen group. Continuing increases in flexibility levels were observed over one week. No significant change over time was noted for the control group.

So, whichever way we look at it, there is no evidence whatsoever that Bowen Technique is helpful for patients suffering from any condition. This clearly means that therapeutic claims made for it are bogus, and that the way the Royal College of Nursing advertised it is misleading to the point of being unethical. By definition, the promotion of bogus treatments is quackery. Ergo, the Royal College of Nursing is promoting quackery.

If that is so, there is of course another question that needs an answer: Why does the Royal College of Nursing promote quackery?

As I see it, there are several possibilities, for instance:

  • They see nothing wrong with the Bowen session.
  • They don’t know better.
  • They don’t adhere to EBM.
  • They don’t care.
  • They were asked to run the session by someone with influence.
  • They believe that nurses want this sort of thing.
  • They think it’s trendy.

I would be fascinated to hear from someone who knows the correct answer.

The BMJ has always been my favourite Medical journal. (Need any proof for this statement? A quick Medline search tells me that I have over 60 publications in the BMJ.) But occasionally, the BMJ also disappoints me a great deal.

One of the most significant disappointments was recently published under the heading of STATE OF THE ART REVIEW. A review that is ‘state of the art’ must fulfil certain criteria; foremost it should be informative, unbiased and correct. The paper I am discussing here has, I think, neither of these qualities. It is entitled ‘Management of chronic pain using complementary and integrative medicine’, and here is its abstract:

Complementary and integrative medicine (CIM) encompasses both Western-style medicine and complementary health approaches as a new combined approach to treat a variety of clinical conditions. Chronic pain is the leading indication for use of CIM, and about 33% of adults and 12% of children in the US have used it in this context. Although advances have been made in treatments for chronic pain, it remains inadequately controlled for many people. Adverse effects and complications of analgesic drugs, such as addiction, kidney failure, and gastrointestinal bleeding, also limit their use. CIM offers a multimodality treatment approach that can tackle the multidimensional nature of pain with fewer or no serious adverse effects. This review focuses on the use of CIM in three conditions with a high incidence of chronic pain: back pain, neck pain, and rheumatoid arthritis. It summarizes research on the mechanisms of action and clinical studies on the efficacy of commonly used CIM modalities such as acupuncture, mind-body system, dietary interventions and fasting, and herbal medicine and nutrients.

The full text of this article is such that I could take issue with almost every second statement in it. Obviously, this would be too long and too boring for this blog. So, to keep it crisp and entertaining, let me copy the (tongue in cheek) ‘letter to the editor’ some of us published in the BMJ as a response to the review:

“Alternative facts are fashionable in politics these days, so why not also in healthcare? The article by Chen and Michalsen on thebmj.com provides a handy set of five instructions for smuggling alternative facts into medicine.

1. Create your own terminology: the term ‘complementary and integrated medicine’ (CIM) is nonsensical. Integrated medicine (a hotly disputed field) already covers complementary and conventional medicine.

2. Pretend to be objective: Chen and Michalsen elaborate on the systematic searches they conducted. But they omit hundreds of sources which do not support their message, which cherry-picks only evidence for the efficacy of the treatments they promote.

3. Avoid negativity: they bypass any material that might challenge what they include. For instance, when discussing therapeutic risks, they omit the disturbing lack of post-marketing surveillance: the reason we lack information on adverse events. They even omit to mention the many fatalities caused by their ‘CIM’.

4. Create an impression of thoroughness: Chen and Michalsen cite a total of 225 references. This apparent scholarly attention to detail masks their misuse of many of they list. Reference 82, for example, is employed to back up the claim that “satisfaction was lowest among complementary medicine users with rheumatoid arthritis, vasculitis, or connective tissue diseases”. In fact, it shows nothing of the sort.

5. Back up your message with broad generalisations: Chen and Michalsen conclude that “Taken together, CIM has an increasing role in the management of chronic pain, but high quality research is needed”. The implication is that all the CIMs mentioned in their figure 1 are candidates for pain control – even discredited treatments such as homeopathy.

In our view, these authors render us a service: they demonstrate to the novice how alternative facts may be used in medicine.”

END OF QUOTE

I am sure you have your own comments and opinions, and I encourage you to post them here or (better) submit them to the BMJ or (best) both.

The website of the HOMEOPATHY HUB gives us intriguing access to the brain of a homeopath. It tells us that “protecting patient choice is at the heart of everything we do. Homeopathy, which is the second largest system of medicine in the world, is a form of treatment which plays a vital role in the lives of hundreds of thousands of people across the UK. There is, however, a movement to try and withdraw homeopathy from the public and make homeopathic medicines difficult to secure. Our intention is to be a central “hub” for accurate information on current campaigns to retain access to homeopathy and details on how you can get involved and make your voice heard. Without public and patient support we will not be successful.”

Here are a few of the above statements that I find doubtful:

  • protecting patient choice – choice requires reliable information; as we will see, this is not provided here;
  • second largest system of medicine in the world – really?
  • plays a vital role – where is the evidence for that claim?
  • movement to try and withdraw homeopathy from the public and make homeopathic medicines difficult to secure – nobody works towards this aim, some people are trying to stop wasting public funds on useless therapies, but that’s quite different, I find;

The HOMEOPATHY HUB recently alerted its readers to the fact that the Charity Commission (CC) is currently conducting a public consultation on whether organisations promoting the use of complementary and alternative medicines (CAM) should have charitable status (https://www.gov.uk/government/consultations/consultation-on-complementary-and-alternative-medicines) and urged its readers to defend homeopathy by responding to the CC offering a “few helpful points” to raise. These 7 points give, I think, a good insight into the thinking of homeopaths. I therefore copy them here and add a few of my own comments below:

  1. there are many types of evidence that should be considered when evaluating the effectiveness of a therapy. These include scientific studies, patient feedback and the clinical experience of  doctors  who  have trained in a CAM discipline.  Within Homeopathy there is considerable evidence which can be found (https://www.hri-research.org)
  2. many conventional therapies and drugs  have inconclusive evidence or prove to be useful in only some cases, for example SSRIs (anti-depressants).  Inconsistent evidence is often the result  of the complexity of both  the medical  condition being treated and the therapy being used. It is not indicative of a therapy that doesn’t work
  3. removing all therapies or interventions that  have inconsistent or inconclusive evidence would seriously limit the  public and the medical profession’s  ability to help treat and ease patients suffering.
  4. all over the world there are doctors, nurses, midwives, vets  and other healthcare professional  who integrate  CAM therapies into their daily  practice because they see effectiveness. They would not use these therapies if they  did  not see their patients  benefitting from them.  For example in the UK, within the NHS hospital setting, outcome studies demonstrate effectiveness of homeopathy. (http://www.britishhomeopathic.org/evidence/results-from-the-homeopathic-hospitals/)
  5. practitioners of many CAM therapies belong to registering bodies which expect their members to comply to the highest professional standards in regards to training and practice
  6. In the UK the producers and suppliers of  CAM treatments (homeopathy, herbal medicine etc) are strictly regulated
  7. as well as  providing valuable information to the  growing  number of people seeking to use CAM as part of their healthcare, CAM charities frequently fund treatment for those people, particularly the elderly and those on a low income, whose health has benefitted from these therapies but who cannot  afford them. This meets the charity’s criterion of  providing a public benefit.

MY COMMENTS

  1. “Patient feedback and the clinical experience of  doctors” may be important but is not what can be considered evidence of therapeutic effectiveness.
  2. Yes, in medicine evidence is often inconsistent; this is why we need to rely on proper assessments of the totality of the reliable data. If that fails to be positive (as is the case for homeopathy and several other forms of alternative medicine), we are well advised not to employ the treatment in question in routine healthcare.
  3. Removing all treatments for which the best evidence fails to show effectiveness – such as homeopathy – would greatly improve healthcare and reduces cost. It is one of the aims of EBM and an ethical imperative.
  4. Yes, some healthcare professionals do use useless therapies. They urgently need to be educated in the principles of EBM. Outcome studies have normally no control groups and therefore are no adequate tools for testing the effectiveness of medical interventions.
  5. The highest professional standards in regards to training and practice of nonsense will still result in nonsense.
  6. The proper regulation of nonsense can only generate proper nonsense.
  7. Yes, CAM charities frequently fund bogus treatments; hopefully (and with the help of readers of this blog), the CC will put an end to this soon.

I think these 7 points by the HOMEOPATHY HUB are a very poor defence of homeopathy. In fact, they are so bad that it is not worth analysing more closely than I did above. Yet, they do provide us with an insight into the homeopathic mind-set and show how illogical, misguided and wrong the arguments of homeopathy enthusiasts really are.

I do encourage you to give your response to the CC – it wound be hard to use better arguments than the homeopaths!!!

As the data suggesting that homeopathy is effective for improving health is – to put it mildly – less than convincing, a frantic search is currently on amongst homeopaths and their followers to identify a specific condition for which the evidence is stronger than for all conditions pooled into one big analysis. If they could show that it works for just one disease, they could celebrate this finding and henceforth use it for refuting doubters stating that highly diluted homeopathic remedies are pure placebos. One such condition is allergic rhinitis; there have been several trials suggesting that homeopathy might be effective for it, and therefore it is only logical that homeopathy-promoters want to summarise these data in order to silence sceptics once and for all.

A new paper ought to be seen in this vein. It is systematic review by the Mathie group with the stated aim “to evaluate the efficacy and effectiveness of homeopathic intervention in the treatment of seasonal or perennial allergic rhinitis (AR).”

Randomized controlled trials evaluating all forms of homeopathic treatment for AR were included in a systematic review (SR) of studies published up to and including December 2015. Two authors independently screened potential studies, extracted data, and assessed risk of bias. Primary outcomes included symptom improvement and total quality-of-life score. Treatment effect size was quantified as mean difference (continuous data), or by risk ratio (RR) and odds ratio (dichotomous data), with 95% confidence intervals (CI). Meta-analysis was performed after assessing heterogeneity and risk of bias.

Eleven studies were eligible for SR. All trials were placebo-controlled except one. Six trials used the treatment approach known as isopathy, but they were unsuitable for meta-analysis due to problems of heterogeneity and data extraction. The overall standard of methods and reporting was poor: 8/11 trials were assessed as “high risk of bias”; only one trial, on isopathy for seasonal AR, possessed reliable evidence. Three trials of variable quality (all using Galphimia glauca for seasonal AR) were included in the meta-analysis: nasal symptom relief at 2 and 4 weeks (RR = 1.48 [95% CI 1.24-1.77] and 1.27 [95% CI 1.10-1.46], respectively) favoured homeopathy compared with placebo; ocular symptom relief at 2 and 4 weeks also favoured homeopathy (RR = 1.55 [95% CI 1.33-1.80] and 1.37 [95% CI 1.21-1.56], respectively). The single trial with reliable evidence had a small positive treatment effect without statistical significance. A homeopathic and a conventional nasal spray produced equivalent improvements in nasal and ocular symptoms.

The authors concluded that the low or uncertain overall quality of the evidence warrants caution in drawing firm conclusions about intervention effects. Use of either Galphimia glauca or a homeopathic nasal spray may have small beneficial effects on the nasal and ocular symptoms of AR. The efficacy of isopathic treatment of AR is unclear.

Extracts of Galphimia glauca (GG) have been used traditionally in South America for the treatment of allergic conditions, with some reports suggesting effectiveness. A 1997 meta-analysis of 11 clinical trials (most of them of very poor quality) of homeopathic GG suggested this therapy to be effective in the treatment of AR. In 2011, I published a review (FACT 2011, 16 200-203) focussed exclusively on the remarkable set of RCTs of homeopathic Galphimia glauca (GG). My conclusions were as follows: three of the four currently available placebo-controlled RCTs of homeopathic GG suggest this therapy is an effective symptomatic treatment for hay fever. There are, however, important caveats. Most essentially, independent replication would be required before GG can be considered for the routine treatment of hay fever. Since then, no new studies have emerged.

I am citing this for two main reasons:

  • There is nothing homeopathic about the principle of using GG for allergic conditions; according to homeopathic theory GG extracts would need to cause allergies for GG to have potential as a homeopathic allergy remedy. Arguably, the GG trials should therefore have been excluded from this meta-analysis for not following the homeopathic principal of ‘like cures like’.
  • All the RCTs of GG were done by the same German research group. There is not a single independent replication of their findings!

Seen from this perspective, the conclusion by Mathie et al, that the use of either Galphimia glauca … may have small beneficial effects on the nasal and ocular symptoms of AR, seems more than a little over-optimistic.

This double-blind RCT aimed to test the efficacy of self-administered acupressure for pain and physical function in adults with knee osteoarthritis (KOA).

150 patients with symptomatic KOA participated and were randomized to

  1. verum acupressure,
  2. sham acupressure,
  3. or usual care.

Verum and sham, but not usual care, participants were taught to self-apply acupressure once daily, five days/week for eight weeks. Assessments were collected at baseline, 4 and 8 weeks. The numeric rating scale (NRS) for pain was administered during weekly phone calls. Outcomes included the WOMAC pain subscale (primary), the NRS and physical function measures (secondary). Linear mixed regression was conducted to test between group differences in mean changes from baseline for the outcomes at eight weeks.

Compared with usual care, both verum and sham participants experienced significant improvements in WOMAC pain, NRS pain and WOMAC function at 8 weeks. There were no significant differences between verum and sham acupressure groups in any of the outcomes.

The authors concluded that self-administered acupressure is superior to usual care in pain and physical function improvement for older people with KOA. The reason for the benefits is unclear and placebo effects may have played a role.

Another very odd conclusion!

The authors’ stated aim was to TEST THE EFFICACY OF ACUPRESSURE. To achieve this aim, they rightly compared it to a placebo (sham) intervention. This comparison did not show any differences between the two. Ergo, the only correct conclusion is that acupressure is a placebo.

I know, the authors (sort of) try to say this in their conclusions: placebo effects may have played a role. But surely, this is more than a little confusing. Placebo effects were quite evidently the sole cause of the observed outcomes. Is it ethical to confuse the public in this way, I wonder.

 

 

Shiatsu is one of those alternative therapies where there is almost no research. Therefore, every new study is of interest, and I was delighted to find this new trial.

Italian researchers tested the efficacy and safety of combining shiatsu and amitriptyline to treat refractory primary headaches in a single-blind, randomized, pilot study. Subjects with a diagnosis of primary headache and who experienced lack of response to ≥2 different prophylactic drugs were randomized in a 1:1:1 ratio to receive one of the following treatments:

  1. shiatsu plus amitriptyline,
  2. shiatsu alone,
  3. amitriptyline alone

The treatment period lasted 3 months and the primary endpoint was the proportion of patients experiencing ≥50%-reduction in headache days. Secondary endpoints were days with headache per month, visual analogue scale, and number of pain killers taken per month.

After randomization, 37 subjects were allocated to shiatsu plus amitriptyline (n = 11), shiatsu alone (n = 13), and amitriptyline alone (n = 13). Randomization ensured well-balanced demographic and clinical characteristics at baseline.

The results show that all the three groups improved in terms of headache frequency, visual analogue scale score, and number of pain killers and there was no between-group difference in the primary endpoint. Shiatsu (alone or in combination) was superior to amitriptyline in reducing the number of pain killers taken per month. Seven (19%) subjects reported adverse events, all attributable to amitriptyline, while no side effects were related with shiatsu treatment.

The authors concluded that shiatsu is a safe and potentially useful alternative approach for refractory headache. However, there is no evidence of an additive or synergistic effect of combining shiatsu and amitriptyline. These findings are only preliminary and should be interpreted cautiously due to the small sample size of the population included in our study.

Yes, I would advocate great caution indeed!

The results could easily be said to demonstrate that shiatsu is NOT effective. There is NO difference between the groups when looking at the primary endpoint. This plus the lack of a placebo-group renders the findings uninterpretable:

  • If we take the comparison 2 versus 3, this might indicate efficacy of shiatsu.
  • If we take the comparison 1 versus 3, it would indicate the opposite.
  • If we finally take the comparison 1 versus 2, it would suggest that the drug was ineffective.

So, we can take our pick!

Moreover, I do object to the authors’ conclusion that “shiatsu is a safe”. For such a statement, we would need sample sizes that are about two dimensions greater that those of this study.

So, what might be an acceptable conclusion from this trial? I see only one that is in accordance with the design and the results of this study:

 

POORLY DESIGNED RESEARCH CANNOT LEAD TO ANY CONCLUSIONS ABOUT THERAPEUTIC EFFICACY OR SAFETY. IT IS A WASTE OF RESOURCES AND A VIOLATION OF RESEARCH ETHICAL.

We have discussed this notorious problem before: numerous charities (such as one that treats HIV and malaria with homeopathy in Botswana, or the one claiming that homeopathy can reverse cancer) are a clear danger to public health. I have previously chosen the example of ‘YES TO LIFE’ and explained that they promote unproven and disproven alternative therapies as cures for cancer (and if you want to get really sickened, look who act as their supporters and advisors). It is clear to me that such behaviour can hasten the death of many vulnerable patients.

Yet, many such charities get tax and reputational benefits by being registered charities in the UK. The question is CAN THIS SITUATION BE JUSTIFIED?

Currently, the UK Charity commission want to answer it. Specifically, they are asking you the following question:

  • Question 1: What level and nature of evidence should the Commission require to establish the beneficial impact of CAM therapies?
  • Question 2: Can the benefit of the use or promotion of CAM therapies be established by general acceptance or recognition, without the need for further evidence of beneficial impact? If so, what level of recognition, and by whom, should the Commission consider as evidence?
  • Question 3: How should the Commission consider conflicting or inconsistent evidence of beneficial impact regarding CAM therapies?
  • Question 4: How, if at all, should the Commission’s approach be different in respect of CAM organisations which only use or promote therapies which are complementary, rather than alternative, to conventional treatments?
  • Question 5: Is it appropriate to require a lesser degree of evidence of beneficial impact for CAM therapies which are claimed to relieve symptoms rather than to cure or diagnose conditions?
  • Question 6: Do you have any other comments about the Commission’s approach to registering CAM organisations as charities?

I am sure that most readers of this blog have something to say about these questions. So, please carefully study the full document, go on the commission’s website, and email your response to: legalcharitablestatus@charitycommission.gsi.gov.uk . Don’t delay it; do it now!

THANK YOU!

On this blog, we have had (mostly unproductive) discussions with homeopath so often that sometimes they sound like a broken disk. I don’t want to add to this kerfuffle; what I hope to do today is to summarise  a certain line of argument which, from the homeopaths’ point of view, seems entirely logical. I do this in the form of a fictitious conversation between a scientist (S) and a classical homeopath (H). My aim is to make the reader understand homeopaths better so that, future debates might be better informed.

HERE WE GO:

S: I have studied the evidence from studies of homeopathy in some detail, and I have to tell you, it fails to show that homeopathy works.

H: This is not true! We have plenty of evidence to prove that patients get better after seeing a homeopath.

S: Yes, but this is not because of the remedy; it is due to non-specific effect like the empathetic consultation with a homeopath. If one controls for these factors in adequately designed trials, the result usually is negative.

I will re-phrase my claim: the evidence fails to show that highly diluted homeopathic remedies are more effective than placebos.

H: I disagree, there are positive studies as well.

S: Let’s not cherry pick. We must always consider the totality of the reliable evidence. We now have a meta-analysis published by homeopaths that demonstrates the ineffectiveness of homeopathy quite clearly.

H: This is because homeopathy was not used correctly in the primary trials. Homeopathy must be individualised for each unique patient; no two cases are alike! Remember: homeopathy is based on the principle that like cures like!!!

S: Are you saying that all other forms of using homeopathy are wrong?

H: They are certainly not adhering to what Hahnemann told us to do; therefore you cannot take their ineffectiveness as proof that homeopathy does not work.

S: This means that much, if not most of homeopathy as it is used today is to be condemned as fake.

H: I would not go that far, but it is definitely not the real thing; it does not obey the law of similars.

S: Let’s leave this to one side for the moment. If you insist on individualised homeopathy, I must tell you that this approach can also be tested in clinical trials.

H: I know; and there is a meta-analysis which proves that it is effective.

S: Not quite; it concluded that medicines prescribed in individualised homeopathy may have small, specific treatment effects. Findings are consistent with sub-group data available in a previous ‘global’ systematic review. The low or unclear overall quality of the evidence prompts caution in interpreting the findings. New high-quality RCT research is necessary to enable more decisive interpretation.

If you call this a proof of efficacy, I would have to disagree with you. The effect was tiny and at least two of the best studies relevant to the subject were left out. If anything, this paper is yet another proof that homeopathy is useless!

H: You simply don’t understand homeopathy enough to say that. I tried to tell you that the remedy must be carefully chosen to fit each unique patient. This is a very difficult task, and sometimes it is not successful – mainly because the homeopaths employed in clinical trials are not skilled enough to find it. This means that, in these studies, we will always have a certain failure rate which, in turn, is responsible for the small average effect size.

S: But these studies are always conducted by experienced homeopaths, and only the very best, most experienced homeopaths were chosen to cooperate in them. Your argument that the trials are negative because of the ineffectiveness of the homeopaths – rather than the ineffectiveness of homeopathy – is therefore nonsense.

H: This is what you say because you don’t understand homeopathy!

S: No, it is what you say because you don’t understand science. How else would you prove that your hypothesis is correct?

H: Simple! Just look at individual cases from the primary studies within this meta-analysis . You will see that there are always patients who did improve. These cases are the proof we need. The method of the RCT is only good for defining average effects; this is not what we should be looking at, and it is certainly not what homeopaths are interested in.

S: Are you saying that the method of the RCT is wrong?

H: It is not always wrong. Some RCTs of homeopathy are positive and do very clearly prove that homeopathy works. These are obviously the studies where homeopathy has been applied correctly. We have to make a meta-analysis of such trials, and you will see that the result turns out to be positive.

S: So, you claim that all the positive studies have used the correct method, while all the negative ones have used homeopathy incorrectly.

H: If you insist to put it like that, yes.

S: I see, you define a trial to have used homeopathy correctly by its result. Essentially you accept science only if it generates the outcome you like.

H: Yes, that sounds odd to you – because you don’t understand enough of homeopathy.

S: No, what you seem to insist on is nothing short of double standards. Or would you accept a drug company claiming: some patients did feel better after taking our new drug, and this is proof that it works?

H: You see, not understanding homeopathy leads to serious errors.

S: I give up.

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.
