This study describes the use of so-called alternative medicine (SCAM) among older adults who report being hampered in daily activities due to musculoskeletal pain. The characteristics of older adults with debilitating musculoskeletal pain who report SCAM use is also examined. For this purpose, the cross-sectional European Social Survey Round 7 from 21 countries was employed. It examined participants aged 55 years and older, who reported musculoskeletal pain that hampered daily activities in the past 12 months.
Of the 4950 older adult participants, the majority (63.5%) were from the West of Europe, reported secondary education or less (78.2%), and reported at least one other health-related problem (74.6%). In total, 1657 (33.5%) reported using at least one SCAM treatment in the previous year.
The most commonly used SCAMs were:
- manual body-based therapies (MBBTs) including massage therapy (17.9%),
- osteopathy (7.0%),
- homeopathy (6.5%)
- herbal treatments (5.3%).
SCAM use was positively associated with:
- younger age,
- physiotherapy use,
- female gender,
- higher levels of education,
- being in employment,
- living in West Europe,
- multiple health problems.
(Many years ago, I have summarized the most consistent determinants of SCAM use with the acronym ‘FAME‘ [female, affluent, middle-aged, educated])
The authors concluded that a third of older Europeans with musculoskeletal pain report SCAM use in the previous 12 months. Certain subgroups with higher rates of SCAM use could be identified. Clinicians should comprehensively and routinely assess SCAM use among older adults with musculoskeletal pain.
I often mutter about the plethora of SCAM surveys that report nothing meaningful. This one is better than most. Yet, much of what it shows has been demonstrated before.
I think what this survey confirms foremost is the fact that the popularity of a particular SCAM and the evidence that it is effective are two factors that are largely unrelated. In my view, this means that more, much more, needs to be done to inform the public responsibly. This would entail making it much clearer:
- which forms of SCAM are effective for which condition or symptom,
- which are not effective,
- which are dangerous,
- and which treatment (SCAM or conventional) has the best risk/benefit balance.
Such information could help prevent unnecessary suffering (the use of ineffective SCAMs must inevitably lead to fewer symptoms being optimally treated) as well as reduce the evidently huge waste of money spent on useless SCAMs.
My second entry into this competition is so special that I will show you its complete, unadulterated abstract. Here it is:
To compare the safety differences between Chinese medicine (CM) and Western medicine (WM) based on Chinese Spontaneous Reporting Database (CSRD).
Reports of adverse events (AEs) caused by CM and WM in the CSRD between 2010 and 2011 were selected. The following assessment indicators were constructed: the proportion of serious AEs (PSE), the average number of AEs (ANA), and the coverage rate of AEs (CRA). Further comparisons were also conducted, including the drugs with the most reported serious AEs, the AEs with the biggest report number, and the 5 serious AEs of interest (including death, anaphylactic shock, coma, dyspnea and abnormal liver function).
The PSE, ANA and CRA of WM were 1.09, 8.23 and 2.35 times higher than those of CM, respectively. The top 10 drugs with the most serious AEs were mainly injections for CM and antibiotics for WM. The AEs with the most reports were rash, pruritus, nausea, dizziness and vomiting for both CM and WM. The proportions of CM and WM in anaphylactic shock and coma were similar. For abnormal liver function and death, the proportions of WM were 5.47 and 3.00 times higher than those of CM, respectively.
Based on CSRD, CM was safer than WM at the average level from the perspective of adverse drug reactions.
Perhaps there will be readers who do not quite understand why I find this paper laughable. Let me try to answer their question by suggesting a few other research subjects of similar farcicality.
- A comparison of the safety of vitamins and chemotherapy.
- A study of the relative safety of homeopathic remedies and antibiotics.
- An investigation into the risks of sky diving in comparison with pullover knitting.
- A study of the pain caused by an acupuncture needle compared to molar extraction.
In case my point is still not clear: comparing the safety of one intervention to one that is fundamentally different in terms of its nature and efficacy does simply make no sense. If one wanted to conduct such an investigation, it would only be meaningful, if one would consider the risk-benefit balance of both treatments.
The fact that this is not done here discloses the above paper as an embarrassing attempt at promoting Traditional Chinese Medicine.

So-called alternative medicine (SCAM) use has been increasingly prevalent among Americans, whereas its relationship with medical non-adherence is unknown. Using the National Health Interview Survey, this analysis evaluated the use of SCAM modalities and their association with cost-related nonadherence to medical care (CRN) among older Americans by gender strata.
Americans, aged 50 or above in the 2012 National Health Interview Survey, were included to evaluate the use of SCAM modalities and their association with CRN. SCAM modalities were categorized as the use of the following in the past 12 months:
- 1) herbal supplements;
- 2) chiropractic or osteopathic manipulations;
- 3) massage;
- 4) Yoga, tai chi, or qigong;
- 5) Mantra/mindfulness/spiritual meditation,
- 6) acupuncture;
- 7) mind-body therapy;
- 8) other SCAM modalities including homeopathy, naturopathy, traditional healers, energy healing therapy, biofeedback, hypnosis, and craniosacral therapy.
CRN was defined as needing medical care but not receiving it due to costs and/or having medical care delayed due to costs in the past 12 months. The investigators developed a multivariable logit model to assess the association of the use of SCAM modalities and CRN controlling for patients age, gender, race, ethnicity, insurance status (Medicare, Medicaid, VA/Tri-care, no-insurance, or private insurance), and comorbid conditions (diabetes, arthritis, back and neck problems, heart condition, stroke, lung and breathing problems, and cancer).
A total of 16,360 older Americans were included in the analysis, with 11,278 (68.9%) reporting at least one SCAM modality use, and 1,992 (12.2%) of them reported CRN. Among the 8 SCAM modalities, compared to those not using SCAM, those who used chiropractic were 94% more likely (p=0.01), those who used Mantra/mindfulness/spiritual meditation were 106% more likely (p<0.01), and those using other modalities were 42% more likely (p=0.07) to report CRN. In contrast, those who used mind-body therapy were 43% less likely (p=0.04) to report CRN. The other 4 modalities did not achieve statistically significant levels although the odds ratios were mostly greater than 1.
The authors argue that the differential association between the SCAM modality use and CRN suggested a complex relationship between the utilization of SCAM and patients’ non-adherence to medical care. It is possible that the out-of-pocket payments for those services significantly increased patients’ cost burden and thus made the use of other medical care unaffordable, and it’s also possible that those who already had low resources were more likely to seek SCAM to substitute for more expensive conventional care. Either of these scenarios would present a serious challenge.
The authors concluded that both men and women are more likely to report financial distress while using various SCAM modalities.
These findings are not easy to interpret. To me, they suggest that, in the US, many consumers have been persuaded to prioritize SCAM over conventional medicine, even if they can ill afford it. It throws a dim light on the US society where some folks seem to struggle to pay for what is essential while continuing to afford the superfluous.
In my view, in a just and non-decadent society, conventional healthcare must be free for everyone at the point of delivery, and SCAM is at best an extra that those who want it should pay out of their own pocket.
I have repeatedly reported about what has been happening with homeopathy in France. For many decades, it had a free ride. Things began to change some 10 years ago.
- In 2014, our book was published in French. I might be fooling myself, but I do hope that it helped to start a ball rolling.
- Subsequently, French skeptics began raising their voices against quackery in general and homeopathy in particular.
- In 2015, Christian Boiron, boss of Boiron, stated about people opposing homeopathy that “Il y a un Ku Klux Klan contre l’homéopathie” THERE IS A KU KLUX KLAN AGAINST HOMEOPATHY”.
- In 2018, 124 doctors published an open letter criticizing the use of so-called alternative medicine (SCAM).
- In the same year, the Collège National des Généralistes Engseignants, the national association for teaching doctors, pointed out that there was no rational justification for the reimbursement of homeopathics nor for the teaching of homeopathy in medical schools, and they stated bluntly that it is necessary to abandon these esoteric methods, which belong in the history books.
- Also in 2018, the University of Lille announced its decision to stop its course on homeopathy. The faculty of medicine’s dean, Didier Gosset, said: It has to be said that we teach medicine based on proof – we insist on absolute scientific rigor – and it has to be said that homeopathy has not evolved in the same direction, that it is a doctrine that has remained on the margins of the scientific movement, that studies on homeopathy are rare, that they are not very substantial. Continuing to teach it would be to endorse it.
- In 2019, the French Academies of Medicine and Pharmacy published a document entitled ‘L’homéopathie en France : position de l’Académie nationale de médecine et de l’Académie nationale de pharmacie’. It stated that L’homéopathie a été introduite à la fin du XVIIIe siècle, par Samuel Hahnemann, postulant deux hypothèses : celle des similitudes (soigner le mal par le mal) et celle des hautes dilutions. L’état des données scientifiques ne permet de vérifier à ce jour aucune de ces hypothèses. Les méta-analyses rigoureuses n’ont pas permis de démontrer une efficacité des préparations homéopathiques. The academies concluded that no French university should offer degrees in homeopathy, and that homeopathy should no longer be funded by the public purse: “no homeopathic preparation should be reimbursed by Assurance Maladie [France’s health insurance] until the demonstration of sufficient medical benefit has been provided. No university degree in homeopathy should be issued by medical or pharmaceutical faculties … The reimbursing of these products by the social security seems aberrant at a time when, for economic reasons, we are not reimbursing many classic medicines because they are more or less considered to not work well enough …”
- Only weeks later, the French health regulator (HAS) recommended with a large majority the discontinuation of the reimbursement of homeopathic products.
- The health minister, Agnès Buzyn, announced “Je me tiendrai à l’avis de la Haute Autorité de santé”.
- Consequently, the powerful French homeopathy lobby mounted political pressure, including a petition with over 1000000 signatures.
- President Macron allegedly was hesitant and considered a range of options, including a reduction of the percentage of reimbursement.
- Apparently, the minister stood up for science and, as rumored, even put her job on the line.
- In July 2019, she announced the end of reimbursement and was quoted saying “J’ai toujours dit que je suivrais l’avis de la Haute Autorité de santé (HAS), j’ai donc décidé d’engager la procédure de déremboursement total“
Since then, homeopathy has indeed been banned from reimbursement. Here is a short update on the current situation:
After the disengagement of the French Social Security system, the world leader in homeopathy has been trying to convince complementary health insurance companies to take up the torch of large-scale reimbursement. Its seduction operation includes a third-party payment solution to boost sales.
From 1 January 2021, homeopathy is no longer reimbursed by Social Security. In March 2020, Boiron, the largest producer of homeopathics, began a restructuring that led to the loss of 560 jobs in France and the closure of one-third of its 31 production and distribution sites. On Thursday, the site of Chauray (Deux-Sèvres) closed after 33 years of activity.
… The CEO of Boiron, Valérie Lorentz-Poinsot, does not have words strong enough to describe the decision of the former Minister of Health, Agnès Buzyn, to delist homeopathy. Since the view issued in June 2019 by the French Health Authority (HAS) noting the ineffectiveness of 1,100 of these products previously reimbursed by the French health service, the reimbursement of homeopathics was reduced from 30% to 15% in 2020, then to 0% on 1 January 2021.
Oh, I almost forgot to mention: the stocks in Boiron roughly halved during the last 3 years
I am pleased to report that our ‘resident homeopathic doctor’ from Germany, Dr. Heinrich Huemmer, posted a review of my new book on Amazon. As his comments are in German, I translated them which was not easy because they are confusing and confused. Now that it’s done, I cannot resist the temptation to show them to you (the references were inserted by me, and refer to my comments below):
First of all, the author, who as a scientist  once had a thoroughly positive attitude towards homeopathy [and in a meta-analysis even attested to it significantly positive results in a certain clinical picture ], explains the principles and procedures in homeopathy in a clear and objective manner.
In explaining the principle of potentization, however, Ernst’s one-dimensional and completely unscientific matter-bound, quasi-medieval understanding of science shines through for the first time. With the assertion, “both the dilution and the similarity rule contradict the laws of nature” he clearly reveals his unscientific thinking, whereby he could have easily relativized this by an inserted differentiation “presently, known laws of nature”.  And not even the following sentence “…we understand very well that it can function only if the known laws of nature would be invalid” is agreed by critically thinking natural scientists.  Also the assertion: “The totality of this evidence does not show that homeopathic remedies would be no more than placebo”, is countered by a well-known – belonging to the skeptic movement – expert of the homeopathic study situation with the remark: “Furthermore, you should read my statements and those of the INH more carefully again: Our statement is that there is no robust/reliable/convincing evidence for efficacy beyond placebo. ALSO NOT “NONE” but “none conclusive”, which yes makes a difference in absolute numbers. Just like “no beer” is different than “not a good beer”. ”  Since patients usually turn to homeopathy only when so-called scientific medicine negates their illnesses and accordingly has nothing to offer them , Ernst’s reference to the fact that patients could “endanger their health” is to be seen as a cheap attempt at discrediting.  The reference that this assessment comes from the Australian National Health and Medical Research Council is not without a particularly piquant note, since this NHMRC may have to be held responsible for a particularly infamous attempt at scientific fraud to the disadvantage of homeopathy.  Also, the alleged “fact” that “[positive] experiences […] are the result of a long, empathetic, sympathetic encounter with a homoeopath…” can be disproved by immediate – also diagnostically verified – cures, which occurred immediately without a long admission or which failed to appear even after several intensive anamneses under most sympathetic admission against all expectations….. Finally Ernst’s argument “the benefit-cost-argument of homeopathy is not positive” is an absolute air number, because the saving of 1 €/patient and year (in case of abolition of the homeopathy-reimbursement) would not even allow a free new glasses-nose-pad…. 
- I am not sure where Homeopathy Heinrich Huemmer (HHH) got the claim from that I, as a scientist, once had a thoroughly positive attitude towards homeopathy. This is not even remotely true! As a very young clinician (40 years ago), I once was quite impressed by homeopathy, never as a scientist (for full details, see my memoir). What HHH seems to display here is his very own misunderstanding about science and scientists: if they are for real (i.e. not pseudoscientists like many of those who research homeopathy), scientists try not to let their personal attitudes get in the way of good science.
- I presume that HHH refers here to this meta-analysis: Homeopathy for postoperative ileus? A meta-analysis. I fear that HHH has yet to learn how to read a scientific paper. Our conclusions were: There is evidence that homeopathic treatment can reduce the duration of ileus after abdominal or gynecologic surgery. However, several caveats preclude a definitive judgment. These results should form the basis of a randomized controlled trial to resolve the issue.
- This made me laugh! Does HHH think that only the handful of homeopathic loons who claim that homeopathy has a scientific basis in the unknown laws of nature are truly scientific? And all the rest are unscientific?
- I doubt that anyone can understand this passage, perhaps not even HHH. My conclusion that “the totality of this evidence does not show that homeopathic remedies are more than placebo” merely expresses what even most homeopaths would admit and is unquestionably correct.
- This statement is untrue in more than one way. Firstly, responsible clinicians never tell a patient that they have nothing more to offer, simply because this is never the case – there is always something a good clinician can do for his/her patient, even if it is just in terms of palliation or moral support. Secondly, we know that German patients opt to use homeopathy for all sorts of reasons, including as first-line therapy and not as a last resort.
- In the book, I refer (and reference the source) to the phenomenon that many homeopaths discourage their patients from vaccination. Unfortunately, this is no ‘cheap attempt’, it is the sad reality. HHH does not even try to dispute it.
- HHH does not like the NHMRC report. Fair enough! But he omits to mention that, in the book, I list a total of 4 further official verdicts. Does HHH assume they are all fraudulent? Is there perhaps a worldwide conspiracy against homeopathy?
- We all know that HHH is enormously proud of his only publication to which he refers here (on this blog, he must have mentioned it a dozen times). However, in the book, I refer to an RCT for making my point. Which is more convincing, a case report or an RCT?
- Here HHH simply demonstrates that he has not understood the concept of cost-effectiveness.
So, what we have here is a near-perfect depiction of a homeopath’s way of thinking. But there is worse in HHH’s comment< I fear.
My book (of 224 pages) scrutinizes – as even its title states – not one but 40 types of so-called alternative medicine (SCAM); 20 of the most effective and 20 of the most dangerous SCAMs. In addition, it covers (in ~ 50 pages) many general topics (like ‘WHAT IS EVIDENCE? or WHY IS SCAM SO POPULAR?). It includes over 200 references to published papers. Yet, HHH reviews and judges the book by commenting exclusively on the meager 5 pages dedicated to homeopathy!
If that does not exemplify the limitations of the homeopathic mind, please tell me what does.
THANK YOU, HHH, FOR MAKING THIS SO CLEAR TO US!
About one in three individuals have elevated blood pressure. This is bad news because hypertension is one of the most important risk factors for cardiovascular events like strokes and heart attacks. Luckily, there are many highly effective approaches for treating elevated blood pressure (diet, life-style, medication, etc.), and the drug management of hypertension has improved over the last few decades.
But unfortunately all anti-hypertensive drugs have side-effects and some patients look towards so-called alternative medicine (SCAM) to normalise their blood pressure. Therefore, we have to ask: are SCAMs effective treatments for hypertension? Because of the prevalence of hypertension, this is a question of great importance for public health.
In 2005, I addressed the issue by publishing a review entitled ‘Complementary/alternative medicine for hypertension: a mini-review‘. Here is its abstract:
Many hypertensive patients try complementary/alternative medicine for blood pressure control. Based on extensive electronic literature searches, the evidence from clinical trials is summarised. Numerous herbal remedies, non-herbal remedies and other approaches have been tested and some seem to have antihypertensive effects. The effect size is usually modest, and independent replications are frequently missing. The most encouraging data pertain to garlic, autogenic training, biofeedback and yoga. More research is required before firm recommendations can be offered.
Since the publication of this paper, more systematic reviews have become available. In order to get an overview of this evidence, I conducted a few simple Medline searches for systematic reviews (SRs) of SCAM published between 2005 and today. I included only SRs that were focussed on just one specific therapy as a treatment of just one specific condition, namely hypertension (omitting SRs with titles such as ‘Alternative treatments for cardiovascular conditions’). Reviews on prevention were also excluded. Here is what I found (the conclusions of each SR is quoted verbatim):
- A 2020 SR of auricular acupressure including 18 RCTs: The results demonstrated a favorable effect of auricular acupressure to reduce blood pressure and improve sleep in patients with hypertension and insomnia. Further studies to better understand the acupoints and intervention times of auricular acupressure are warranted.
- A 2020 SR of Chinese herbal medicines (CHM) including 30 studies: CHM combined with conventional Western medicine may be effective in lowering blood pressure and improving vascular endothelial function in patients with hypertension.
- A 2020 SR of Tai chi including 28 RCTs: Tai Chi could be recommended as an adjuvant treatment for hypertension, especially for patients less than 50 years old.
- A 2020 SR of Tai chi including 13 trials: Tai chi is an effective physical exercise in treating essential hypertension compared with control interventions.
- A 2020 SR of Tai chi including 31 controlled clinical trials: Tai Ji Quan is a viable antihypertensive lifestyle therapy that produces clinically meaningful BP reductions (i.e., 10.4 mmHg and 4.0 mmHg of SBP and DBP reductions, respectively) among individuals with hypertension.
- A 2020 SR of pycnogenol including 7 trials: the present meta-analysis does not suggest any significant effect of pycnogenol on BP.
- A 2019 SR of Policosanol including 19 studies: Policosanol could lower SBP and DBP significantly; future long term studies are required to confirm these findings in the general population.
- A 2019 SR of dietary phosphorus including 14 studies: We found no consistent association between total dietary phosphorus intake and BP in adults in the published literature nor any randomized trials designed to examine this association.
- A 2019 SR of ginger including 6 RCTs: ginger supplementation has favorable effects on BP.
- A 2019 SR of corn silk tea (CST) including 5 RCTs: limited evidence showed that CST plus antihypertensive drugs might be more effective in lowering blood pressure compared with antihypertensive drugs alone.
- A 2019 SR of blood letting including 7 RCTs: no definite conclusions regarding the efficacy and safety of BLT as complementary and alternative approach for treatment of hypertension could be drew due to the generally poor methodological design, significant heterogeneity, and insufficient clinical data.
- A 2019 SR of Xiao Yao San (XYS) including 17 trials: XYS adjuvant to antihypertensive drugs maybe beneficial for hypertensive patients in lowering BP, improving depression, regulating blood lipids, and inhibiting inflammation.
- A 2019 SR of Chinese herbal medicines including 9 RCTs: Chinese herbal medicine as complementary therapy maybe beneficial for postmenopausal hypertension.
- A 2019 Cochrane review of guided imagery including 2 trials: There is insufficient evidence to inform practice about the use of guided imagery for hypertension in pregnancy.

- A 2018 SR of acupuncture including 30 RCTs: there is inadequate high quality evidence that acupuncture therapy is useful in treating hypertension.
- A 2018 SR of co-enzyme Q10 including 17 RCTs: CoQ10 supplementation may result in reduction in SBP levels, but did not affect DBP levels among patients with metabolic diseases.
- A 2018 SR of a traditional Chinese formula Longdanxiegan decoction (LDXGD) including 9 trials: Due to poor methodological quality of the included trials, as well as potential reporting bias, our review found no conclusive evidence for the effectiveness of LDXGD in treating hypertension.
- A 2018 SR of viscous fibre including 22 RCTs: Viscous soluble fiber has an overall lowering effect on SBP and DBP.
- A 2017 SR of yoga breathing exercise (pranayama) including 13 studies: The pranayama’s effect on BP were not robust against selection bias due to the low quality of studies. But, the lowering BP effect of pranayama is encouraging.
- A 2017 SR of dietary nitrate supplementation including 13 trials: Positive effects of medium-term dietary nitrate supplementation on BP were only observed in clinical settings, which were not corroborated by more accurate methods such as 24-h ambulatory and daily home monitorings.
- A 2017 SR of Vitamin D supplementation including 8 RCTs: vitamin D is not an antihypertensive agent although it has a moderate SBP lowering effect.

ALMOST 100 NEW SRs!
To be honest, if I had known the volume of the material, I would probably not have tackled this task. Since the publication of my mini-review in 2005, there has been an explosion of similar papers:
- 1 in 2005
- 2 in 2006
- 3 in 2007
- 2 in 2008
- 1 in 2009
- 4 in 2010
- 2 in 2011
- 8 in 2012
- 8 in 2013
- 12 in 2014
- 12 in 2015
- 6 in 2016
- 9 in 2017
- 7 in 2018
- 12 in 2019
As this is based on very simple Medline searches, the list is certainly not complete. Despite this fact, several conclusions seem to emerge:
- There is no shortage of SCAMs that have been tested for hypertension.
- Most seem to have positive effects; in many cases, they seem too good to be true.
- Many of the SRs are of poor methodological quality, based on poor quality primary studies, published in less than reputable journals. Some SRs, for instance, include studies without a control group which is likely to lead to false-positive overall conclusions about the effectiveness of the SCAM in question.
- In recent years, there are more and more SRs by Chinese authors focussed on Chinese herbal mixtures that are unknown and unobtainable outside China. These SRs are invariably based on studies published in Chinese language in journals that are inaccessible. This means it is almost impossible for the reader, reviewer or editor to check their accuracy. The reliability of the conclusions of these SRs must therefore be doubted.
- Most of the primary studies included in the SRs lack long-term data. Thus the usefulness of the SCAM in question is questionable.
- With several of the SCAMs, the dose of the treatment and treatment schedule is less than clear. For instance, one might ask how frequently a patient should have acupuncture to control her hypertension.
- Some of the SCAMs assessed in these SRs seem of doubtful practicality. For instance, it might not be feasible nor economical for patients to receive regular acupuncture to manage their blood pressure.
- Several contradictions emerge from some of the SRs of the same modality. This is particularly confusing because SRs are supposed to be the most reliable type of evidence. In most instances, however, the explanation can easily be found by looking at the quality of the SRs. If SRs are based on uncontrolled studies, or if they fail to critically evaluate the reliability of the included primary trials, they are likely to arrive at conclusions that are too positive. Examples for such confusion are the multiple SRs of co-enzyme Q10 or the three yoga SRs of 2014.
- Because of this confusion, SCAM advocates are able to select false-positive SRs to support their opinion that SCAM is effective.
- Despite a substantial amount of positive evidence, none of the SCAMs have become part of the routine in the management of hypertension. A 2013 statement by the American Heart Association entitled Beyond medications and diet: alternative approaches to lowering blood pressure: a scientific statement from the american heart association concluded that it is reasonable for all individuals with blood pressure levels >120/80 mm Hg to consider trials of alternative approaches as adjuvant methods to help lower blood pressure when clinically appropriate. A suggested management algorithm is provided, along with recommendations for prioritizing the use of the individual approaches in clinical practice based on their level of evidence for blood pressure lowering, risk-to-benefit ratio, potential ancillary health benefits, and practicality in a real-world setting.
What lessons might this brief overview of SRs teach us? I think the following points are worth considering:
- Systematic reviews are the best type of evidence we have for estimating the effectiveness of treatments. But it is essential that they include a strong element of CRITICAL evaluation of the primary studies. Without it, a SR is incomplete and potentially counter-productive.
- The primary studies of SCAM are far too often of poor quality. This means that researchers should thrive to improve the rigour of their investigations.
- Both poor-quality primary studies and uncritically conducted SRs are prone to yielding findings that are too good to be true.
- Editors and reviewers have a responsibility to prevent the publication of trials and SRs that are of poor quality and thus likely to mislead us.
- Those SCAMs that have shown promising effects on hypertension (for instance Tai chi) should now be submitted to further independent scrutiny to find out whether their efficacy and usefulness can be confirmed, for instance, by 24-h ambulatory and daily home blood pressure monitoring and studies testing their acceptability in real life settings. Subsequently, we ought to determine whether the SCAM in question can be reasonably integrated in routine blood pressure management.
- The adjunctive use of a SCAM that has been proven to be effective and practical seems a reasonable approach. Yet, it requires proper scientific scrutiny.
- There is a paucity of cost-effectiveness studies and investigations of the risks of SCAM which needs to be addressed before any SCAM is considered for routine care.
The Lightning Process (LP) is a commercial programme developed by Phil Parker based on ideas from osteopathy, life coaching and neuro-linguistic programming. It has been endorsed by celebrities like Martine McCutcheon and Esther Rantzen, who credits it for her daughter’s recovery from ME. Parker claims that LP works by teaching people to use their brain to “stimulate health-promoting neural pathways”. One young patient once described it as follows: “Whenever you get a negative thought, emotional symptom, you are supposed to turn on one side and with your arm movements in a kind if stop motion, just say STOP very firmly and that is supposed to cut off the adrenaline response.”
Allegedly, the LP teaches individuals to recognize when they are stimulating or triggering unhelpful physiological responses and to avoid these, using a set of standardized questions, new language patterns and physical movements with the aim of improving a more appropriate response to situations. The LP involves three group sessions on consecutive days where participants are taught theories and skills, which are then practised through simple steps, posture and coaching.
A few days ago, someone asked my help writing to me: Norwegian newspaper is attacking patients for objecting to a clinical trial of the lightning process which is horrible quackery. LP is being backed by some people in Norwegian health authorities. Could you bring attention to how disgraceful this is please? I promised to look into it. Hence this post.
My searches located just one single trial. It seems to be the only controlled clinical study available. Here it is:
Design: Pragmatic randomised controlled open trial. Participants were randomly assigned to SMC or SMC+LP. Randomisation was minimised by age and gender.
Setting: Specialist paediatric CFS/ME service.
Patients: 12-18 year olds with mild/moderate CFS/ME.
Main outcome measures: The primary outcome was the the 36-Item Short-Form Health Survey Physical Function Subscale (SF-36-PFS) at 6 months. Secondary outcomes included pain, anxiety, depression, school attendance and cost-effectiveness from a health service perspective at 3, 6 and 12 months.
Results: We recruited 100 participants, of whom 51 were randomised to SMC+LP. Data from 81 participants were analysed at 6 months. Physical function (SF-36-PFS) was better in those allocated SMC+LP (adjusted difference in means 12.5(95% CI 4.5 to 20.5), p=0.003) and this improved further at 12 months (15.1 (5.8 to 24.4), p=0.002). At 6 months, fatigue and anxiety were reduced, and at 12 months, fatigue, anxiety, depression and school attendance had improved in the SMC+LP arm. Results were similar following multiple imputation. SMC+LP was probably more cost-effective in the multiple imputation dataset (difference in means in net monetary benefit at 12 months £1474(95% CI £111 to £2836), p=0.034) but not for complete cases.
Conclusion: The LP is effective and is probably cost-effective when provided in addition to SMC for mild/moderately affected adolescents with CFS/ME.
The trial was designed as an ‘A+B versus B’ study which practically always generates a positive outcome. It did not control for placebo effects and is, in my humble view, worthless and arguably unethical. It certainly does not warrant the conclusion that LB is effective or cost-effective.
I do not doubt that the LP-children improved, but I see no reason to believe that this had anything to do with LP. It could have been (and most likely was) caused by the intense attention that these kids received over three days. Giving them a daily ice-cream and some kindness might (and probably would) have produced even better outcomes.
So, what do we call a therapy for which numerous, far-reaching claims are being made, which is based on implausible assumptions, which is unproven, and for which people have to pay dearly?
The last time I looked, it was called quackery.
[If you do not like black humour or sarcasm, please do NOT read this post!!!]
Donald Trump just announced that, at Easter, he wants to see churches packed, his way of saying the lock-down is over because it is damaging the economy. Many others have put forward similar arguments and have pointed out that caring for the vulnerable, sick, old, etc. creates an economic burden that might eventually kill more people than it saves (see for instance ‘Economic crash could cost more lives than coronavirus, study warns‘).
Many people have also argued that homeopathy is unjustly vilified because it is truly a wholesome and safe medicine that should be used routinely. The notion here is that, alright, the evidence is not brilliant, but 200 years of experience and millions of fans cannot be ignored.
I have been wondering whether these two lines of thinking could not be profitably combined. Here is my suggestion based on the following two axioms.
- The economy is important for all our well-being.
- Homeopaths have a point in that the value of experience must not be ignored.
What follows is surprisingly simple: in view of the over-riding importance of the economy, let’s prioritise it over health. As it would look bad to deny those poor corona victims all forms of healthcare, let’s treat them homeopathically. This would make lots of people happy:
- those who think the economy must take precedent,
- those who fear the huge costs of saving corona patients (homeopathy is very cheap),
- those who argued for decades that we never gave homeopathy a fighting chance to show its worth.
There is a downside, of course. There would be a most lamentable mortality rate. But, to paraphrase Dominic Cummings, if a few oldies have to snuff it, so be it!
Once we get used to this innovative approach – I suggest we call it integrative medicine – we might even consider adopting it for other critical situations. When we realise, for instance, that the pension pots are empty, we could officially declare that homeopathy is the ideal medicine for anybody over 60.
What do you think?
Homeopathy has had a long and profitable ride in France; nowhere else in Europe is it more popular, nowhere in Europe are the profit margins higher, and nowhere have I seen pharmacists pushing so hard to earn a few extra Euros on useless homeopathic remedies.
But, since a few months, sceptics have started to raise their voices and object to homeopathic reimbursement (currently at the rate of 30%) and to homeopathy in general.
- A group of doctors protested against homeopathy by publishing an open letter in ‘Le Figaro’.
- The French Academies of Medicine and Pharmacy published a report confirming the lack of evidence for homeopathy.
- The medical school in Lille suspended its degree in homeopathy.
The French health secretary, the oncologist Dr Agnès Buzyn, reacted wisely, in my view. She initially stated that the effect of homeopathy is ‘probably a placebo effect‘. Subsequently, she asked the regulator, La Haute Autorite de Sante (HAS), to look into the matter and prepare a full analysis of the evidence. This report has now been published.
An article in ‘FRANCE INFO’ reports that HAS found no good evidence in support of the ~ 1 200 homeopathic remedies currently on the French market. The document is currently being considered by Dr Buzyn who will announce her decision about reimbursement in June. It is considered to be highly likely that she will stop reimbursement.
If so, consumers will soon have to pay in full for homeopathic preparations out of their own pocket. In addition, they would have to pay the VAT, and it is foreseeable that this change would signal the end of the French consumers’ love affair with homeopathy. This development is bound to seriously hurt Boiron, the world’s largest producer of homeopathics. The firm has already announced that they suspended its trading on the stock market and is now arguing that the move would endanger its sizable workforce.
The question I now ask myself is whether Boiron is powerful enough to do something about all this. Personally, I have been impressed by the rational approach of Dr Buzyn. She will no doubt see through Boiron’s bogus argument of saving a form of obsolete quackery in the name of employment. Therefore, I expect that the days of homeopathy’s reimbursement in France are counted.
(For those who can read French, I add the original ‘ FRANCE INFO’ article below.)
Avis définitif en juin
Cet avis avait été réclamé par la ministre de la Santé il y a plusieurs mois face à la montée de la polémique entre médecins pro et anti-homéopathie. 124 médecins avaient relancé le débat l’an dernier en qualifiant les homéopathes de “charlatans”.
Désormais, lors d’une phase contradictoire, les laboratoires vont pouvoir répondre à la HAS, qui rendra son avis définitif en juin. La ministre de la Santé, Agnès Buzyn, avait par le passé annoncé qu’elle se rangerait à cet avis.
1 000 emplois menacés, selon Boiron
Les pro-homéopathie eux, s’insurgent. Selon eux, les granules ne coûtent que 130 millions d’euros par an à la Sécurité sociale, contre 20 milliards pour les médicaments classiques. Et il existe d’après eux, au minimum, un effet placebo. Pour les laboratoires Boiron, leader mondial du secteur, si l’homéopathie n’est plus remboursée, ce sont 1 000 emplois qui sont directement menacés.
Par ailleurs, dans un communiqué commun, trois laboratoires (Boiron, Lehning et Weleda) s’émeuvent de découvrir à travers un média la teneur d’un avis d’une agence indépendante qui devait être tenu confidentiel. Les laboratoires Boiron précisent à franceinfo qu’ils n’ont pas encore reçu le projet d’avis de la Haute autorité de santé. Boiron, entreprise française cotée, annonce “suspendre” son cours de bourse.
Whenever there are discussions about homeopathy (currently, they have reached fever-pitch both in France and in Germany), one subject is bound to emerge sooner or later: its cost. Some seemingly well-informed person will exclaim that USING MORE HOMEOPATHY WILL SAVE US ALL A LOT OF MONEY.
Of course, homeopathic remedies tend to cost, on average, less than conventional treatments. But that is beside the point. A car without an engine is also cheaper than one with an engine. Comparing the costs of items that are not comparable is nonsense.
What we need are proper analyses of cost-effectiveness. And these studies clearly fail to prove that homeopathy is a money-saver.
Even researchers who are well-known for their pro-homeopathy stance have published a systematic review of economic evaluations of homeopathy. They included 14 published assessments, and the more rigorous of these investigations did not show that homeopathy is cost-effective. The authors concluded that “although the identified evidence of the costs and potential benefits of homeopathy seemed promising, studies were highly heterogeneous and had several methodological weaknesses. It is therefore not possible to draw firm conclusions based on existing economic evaluations of homeopathy“.
Probably the most meaningful study in this area is an investigation by another pro-homeopathy research team. Here is its abstract:
This study aimed to provide a long-term cost comparison of patients using additional homeopathic treatment (homeopathy group) with patients using usual care (control group) over an observation period of 33 months.
Health claims data from a large statutory health insurance company were analysed from both the societal perspective (primary outcome) and from the statutory health insurance perspective (secondary outcome). To compare costs between patient groups, homeopathy and control patients were matched in a 1:1 ratio using propensity scores. Predictor variables for the propensity scores included health care costs and both medical and demographic variables. Health care costs were analysed using an analysis of covariance, adjusted for baseline costs, between groups both across diagnoses and for specific diagnoses over a period of 33 months. Specific diagnoses included depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache.
Data from 21,939 patients in the homeopathy group (67.4% females) and 21,861 patients in the control group (67.2% females) were analysed. Health care costs over the 33 months were 12,414 EUR [95% CI 12,022-12,805] in the homeopathy group and 10,428 EUR [95% CI 10,036-10,820] in the control group (p<0.0001). The largest cost differences were attributed to productivity losses (homeopathy: EUR 6,289 [6,118-6,460]; control: EUR 5,498 [5,326-5,670], p<0.0001) and outpatient costs (homeopathy: EUR 1,794 [1,770-1,818]; control: EUR 1,438 [1,414-1,462], p<0.0001). Although the costs of the two groups converged over time, cost differences remained over the full 33 months. For all diagnoses, homeopathy patients generated higher costs than control patients.
The analysis showed that even when following-up over 33 months, there were still cost differences between groups, with higher costs in the homeopathy group.
A recent analysis confirms this situation. It concluded that patients who use homeopathy are more expensive to their health insurances than patients who do not use it. The German ‘Medical Tribune’ thus summarised the evidence correctly when stating that ‘Globuli are m0re expensive than conventional therapies’. This quote mirrors perfectly the situation in Switzerland which as been summarised as follows: ‘Globuli only cause unnecessary healthcare costs‘.
But homeopaths (perhaps understandably) seem reluctant to agree. They tend to come out with ever new arguments to defend the indefensible. They claim, for instance, that prescribing a homeopathic remedy to a patient would avoid giving her a conventional treatment that is not only more expensive but also has side-effects which would cause further expense to the system.
To some, this sounds perhaps reasonable (particularly, I fear, to some politicians), but it should not be reasonable argument for responsible healthcare professionals.
Because it could apply only to the practice of bad and unethical medicine: if a patient is ill and needs a medical treatment, she does certainly not need something that is ineffective, like homeopathy. If she is not ill and merely wants a placebo, she needs assurance, compassion, empathy, understanding and most certainly not an expensive and potentially harmful conventional therapy.
To employ the above analogy, if someone needs transport, she does not need a car without an engine!
So, whichever way we twist or turn it, the issue turns out to be quite simple:
WHITHOUT EFFECTIVENESS, THERE CAN BE NO COST-EFFECTIVENESS!
