Yesterday, BBC NEWS published the following interesting text about a BBC4 broadcast entitled ‘THE ROYAL ACTIVIST’ aired on the same day:
Prince Charles has been a well-known supporter of complementary medicine. According to a… former Labour cabinet minister, Peter Hain, it was a topic they shared an interest in.
“He had been constantly frustrated at his inability to persuade any health ministers anywhere that that was a good idea, and so he, as he once described it to me, found me unique from this point of view, in being somebody that actually agreed with him on this, and might want to deliver it.”
Mr Hain added: “When I was Secretary of State for Northern Ireland in 2005-7, he was delighted when I told him that since I was running the place I could more or less do what I wanted to do.***
“I was able to introduce a trial for complementary medicine on the NHS, and it had spectacularly good results, that people’s well-being and health was vastly improved.
“And when he learnt about this he was really enthusiastic and tried to persuade the Welsh government to do the same thing and the government in Whitehall to do the same thing for England, but not successfully,” added Mr Hain.
*** obviously there is no homeopathic remedy for megalomania (but that’s a different story)
SPECTACULARLY GOOD RESULTS?
Let’s have a look at the ‘trial’ and its results. An easily accessible report provides the following details about it:
From February 2007 to February 2008, Get Well UK ran the UK’s first government-backed complementary therapy pilot. Sixteen practitioners provided treatments including acupuncture, osteopathy and aromatherapy, to more than 700 patients at two GP practices in Belfast and Derry.
The BBC made an hour long documentary following our trials and tribulations, which was broadcast on BBC1 NI on 5 May 2008.
Aims and Objectives
The aim of the project was to pilot services integrating complementary medicine into existing primary care services in Northern Ireland. Get Well UK provided this pilot project for the Department for Health, Social Services and Public Safety (DHSSPS) during 2007.
The objectives were:
- To measure the health outcomes of the service and monitor health improvements.
- To redress inequalities in access to complementary medicine by providing therapies through the NHS, allowing access regardless of income.
- To contribute to best practise in the field of delivering complementary therapies through primary care.
- To provide work for suitably skilled and qualified practitioners.
- To increase patient satisfaction with quick access to expert care.
- To help patients learn skills to improve and retain their health.
- To free up GP time to work with other patients.
- To deliver the programme for 700 patients.
The results of the pilot were analysed by Social and Market Research, who produced this report.
The findings can be summarised as follows:
Following the pilot, 80% of patients reported an improvement in their symptoms, 64% took less time off work and 55% reduced their use of painkillers.
In the pilot, 713 patients with a range of ages and demographic backgrounds and either physical or mental health conditions were referred to various complementary and alternative medicine (CAM) therapies via nine GP practices in Belfast and Londonderry. Patients assessed their own health and wellbeing pre and post therapy and GPs and CAM practitioners also rated patients’ responses to treatment and the overall effectiveness of the scheme.
• 81% of patients reported an improvement in their physical health
• 79% reported an improvement in their mental health
• 84% of patients linked an improvement in their health and wellbeing directly to their CAM treatment
• In 65% of patient cases, GPs documented a health improvement, correlating closely to patient-reported improvements
• 94% of patients said they would recommend CAM to another patient with their condition
• 87% of patient indicated a desire to continue with their CAM treatment
Painkillers and medication
• Half of GPs reported prescribing less medication and all reported that patients had indicated to them that they needed less
• 62% of patients reported suffering from less pain
• 55% reported using less painkillers following treatment
• Patients using medication reduced from 75% before treatment to 61% after treatment
• 44% of those taking medication before treatment had reduced their use afterwards
Health service and social benefits
• 24% of patients who used health services prior to treatment (i.e. primary and secondary care, accident and emergency) reported using the services less after treatment
• 65% of GPs reported seeing the patient less following the CAM referral
• Half of GPs said the scheme had reduced their workload and 17% reported a financial saving for their practice
• Half of GPs said their patients were using secondary care services less.
Impressed? Well, in case you are, please consider this:
- there was no control group
- therefore it is not possible to attribute any of the outcomes to the alternative therapies offered
- they could have been due to placebo-effects
- or to the natural history of the disease
- or to regression towards the mean
- or to social desirability
- or to many other factors which are unrelated to the alternative treatments provided
- most outcome measures were not objectively verified
- the patients were self-selected
- they would all have had conventional treatments in parallel
- this ‘trial’ was of such poor quality that its findings were never published in a peer-reviewed journal
- this was not a ‘trial’ but a ‘pilot study’
- pilot studies are not normally for measuring outcomes but for testing the feasibility of a proper trial
- the research expertise of the investigators was close to zero
- the scientific community merely had pitiful smiles for this ‘trial’ when it was published
- neither Northern Ireland nor any other region implemented the programme despite its “spectacularly good results”.
So, is the whole ‘trial’ story an utterly irrelevant old hat?
Certainly not! Its true significance does not lie in the fact that a few amateurs are trying to push bogus treatments into the NHS via the flimsiest pseudo-research of the century. The true significance, I think, is that it shows how Prince Charles, once again, oversteps the boundaries of his constitutional role.
If you are pregnant, a ‘breech presentation’ is not good news. It occurs when the fetus presents ‘bottom-down’ in the uterus. There are three types:
- Breech with extended legs (frank) – 85% of cases
- Breech with fully flexed legs (complete)
- Footling (incomplete) with one or both thighs extended
The significance of breech presentation is its association with higher perinatal mortality and morbidity when compared to cephalic presentations. This is due both to pre-existing congenital malformation, increased incidence of breech in premature deliveries and increased risk of intrapartum trauma or asphyxia. Caesarean section has been adopted as the ‘normal’ mode of delivery for term breech presentations in Europe and the USA, as the consensus is that this reduces the risk of birth-related complications.
But Caesarian section is also not a desirable procedure. Something far less invasive would be much more preferable, of course. This is where the TCM-practitioners come in. They claim they have the solution: moxibustion, i.e. the stimulation of acupuncture points by heat. But does it really work? Can it turn the fetus into the correct position?
This new study aimed to assess the efficacy of moxibustion (heating of the acupuncture needle with an igniting charcoal moxa stick) with acupuncture for version of breech presentations to reduce their rate at 37 weeks of gestation and at delivery. It was a randomized, placebo-controlled, single-blind trial including 328 pregnant women recruited in a university hospital center between 33 4/7 and 35 4/7 weeks of gestation. Moxibustion with acupuncture or inactivated laser (placebo) treatment was applied to point BL 67 for 6 sessions. The principal endpoint was the percentage of fetuses in breech presentation at 37 2/7 weeks of gestation.
The results show that the percentage of fetuses in breech presentation at 37 2/7 weeks of gestation was not significantly different in both groups (72.0 in the moxibustion with acupuncture group compared with 63.4% in the placebo group).
The authors concluded that treatment by moxibustion with acupuncture was not effective in correcting breech presentation in the third trimester of pregnancy.
You might well ask why on earth anyone expected that stimulating an acupuncture point would turn a fetus in the mother’s uterus into the optimal position that carries the least risk during the process of giving birth. This is what proponents of this technique say about this approach:
During a TCM consultation to turn a breech baby the practitioner will take a comprehensive case history, make a diagnosis and apply the appropriate acupuncture treatment. They will assess if moxibustion might be helpful. Practitioners will then instruct women on how to locate the appropriate acupuncture points and demonstrate how to safely apply moxa at home. The acupuncture point UB 67 is the primary point selected for use because it is the most dynamic point to activate the uterus. Its forte is in turning malpositioned babies. It is located on the outer, lower edge of both little toenails. According to TCM theory, moxa has a tonifying and warming effect which promotes movement and activity. The nature of heat is also rising. This warming and raising effect is utilised to encourage the baby to become more active and lift its bottom up in order to gain adequate momentum to summersault into the head down position. This technique can also be used to reposition transverse presentation, a situation where the baby’s has its shoulder or back pointing down, or is lying sideways across the abdomen.
Not convinced? I can’t say I blame you!
Clearly, we need to know what the totality of the most reliable evidence shows; and what better than a Cochrane review to inform us about it? Here is what it tells us:
Moxibustion was not found to reduce the number of non-cephalic presentations at birth compared with no treatment (P = 0.45). Moxibustion resulted in decreased use of oxytocin before or during labour for women who had vaginal deliveries compared with no treatment (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.13 to 0.60). Moxibustion was found to result in fewer non-cephalic presentations at birth compared with acupuncture (RR 0.25, 95% CI 0.09 to 0.72). When combined with acupuncture, moxibustion resulted in fewer non-cephalic presentations at birth (RR 0.73, 95% CI 0.57 to 0.94), and fewer births by caesarean section (RR 0.79, 95% CI 0.64 to 0.98) compared with no treatment. When combined with a postural technique, moxibustion was found to result in fewer non-cephalic presentations at birth compared with the postural technique alone (RR 0.26, 95% CI 0.12 to 0.56).
In other words, there is indeed some encouraging albeit not convincing evidence! How can this be? There is no plausible explanation why this treatment should work!
But there is a highly plausible explanation why the results of many of the relevant trials are false-positive thus rendering a meta-analysis false-positive as well. I have repeatedly pointed out on this blog that practically all Chinese TCM-studies report (false) positive results; and many of the studies included in this review were done in China. The Cochrane review provides a strong hint about the lack of rigor in its ‘plain language summary’:
The included trials were of moderate methodological quality, sample sizes in some of the studies were small, how the treatment was applied differed and reporting was limited. While the results were combined they should be interpreted with caution due to the differences in the included studies. More evidence is needed concerning the benefits and safety of moxibustion.
So, would I recommend moxibustion for breech conversion? I don’t think so!
An article in the ‘Huffpost Healthy Living’ recently discussed “the top three things that surprise people about acupuncture”. On closer inspection, they turn out to be the top three untruths about acupuncture. Here is (in italics and slightly abbreviated) what the article said.
Acupuncture is not just for pain
…It’s true that acupuncture can work wonders on pain conditions…However, acupuncture can alleviate a wide variety of ailments that have nothing to do with physical pain. Whether you have digestive issues, gynecological conditions, emotional concerns such as anxiety and depression, asthma, seasonal allergies, you name it, acupuncture can help address your symptoms.
Acupuncturists go to school for a long time
People tend to be unaware of the extent to which acupuncturists train to become licensed in their profession. Many assume becoming an acupuncturist is similar to becoming a massage therapist or Reiki practitioner or yoga instructor… At minimum, a licensed acupuncturist in the United States has been to three years of graduate school. Four years is more common. They hold master’s degrees. Some acupuncturists with doctorates have studied at the graduate level for five-plus years. Upon graduating from an accredited school, all acupuncturists must pass multiple board exams to become licensed in their state. In addition to the academic and state requirements for practicing acupuncture, many acupuncturists seek hands-on training and mentorship in the form of apprenticeships and continuing education seminars.
Acupuncture is relaxing
Acupuncture needles are surprisingly thin. They do not bear any resemblance to needles that are used for injections or to draw blood… In most cases, the insertion of acupuncture needles does not hurt…Once the needles are in, they start working their magic, which is where the relaxation part comes in. Acupuncture helps shift your body out of sympathetic mode (fight or flight) and into parasympathetic mode (rest and digest). It mellows out the nervous system, decreases muscular tension, and helps quiet internal chatter…
AND NOW THE FACTS:
1) There is not a single condition for which the evidence is truly compelling demonstrating that acupuncture is more than a placebo. Certainly there is no good evidence that acupuncture works for digestive issues, gynecological conditions, emotional concerns such as anxiety and depression, asthma or seasonal allergies.
2) In most countries, anyone can call themselves an acupuncturist, regardless of background or training.
3) The relaxing element of an acupuncture session is foremost the fact that patients lie down and have to keep still for 20 minutes or so. The insertion of needles does cause mild pain in many patients, and the claim about parasympathetic mode is mostly phantasy.
I despair about the nonsense that is published about alternative medicine on a daily basis – not because I have an axe to grind, but because it misleads patients into making wrong therapeutic decisions.
A recent meta-analysis evaluated the efficacy of acupuncture for treatment of irritable bowel syndrome (IBS) and arrived at bizarrely positive conclusions.
The authors state that they searched 4 electronic databases for double-blind, placebo-controlled trials investigating the efficacy of acupuncture in the management of IBS. Studies were screened for inclusion based on randomization, controls, and measurable outcomes reported.
Six RCTs were included in the meta-analysis, and 5 articles were of high quality. The pooled relative risk for clinical improvement with acupuncture was 1.75 (95%CI: 1.24-2.46, P = 0.001). Using two different statistical approaches, the authors confirmed the efficacy of acupuncture for treating IBS and concluded that acupuncture exhibits clinically and statistically significant control of IBS symptoms.
As IBS is a common and often difficult to treat condition, this would be great news! But is it true? We do not need to look far to find the embarrassing mistakes and – dare I say it? – lies on which this result was constructed.
The largest RCT included in this meta-analysis was neither placebo-controlled nor double blind; it was a pragmatic trial with the infamous ‘A+B versus B’ design. Here is the key part of its methods section: 116 patients were offered 10 weekly individualised acupuncture sessions plus usual care, 117 patients continued with usual care alone. Intriguingly, this was the ONLY one of the 6 RCTs with a significantly positive result!
The second largest study (as well as all the other trials) showed that acupuncture was no better than sham treatments. Here is the key quote from this trial: there was no statistically significant difference between acupuncture and sham acupuncture.
So, let me re-write the conclusions of this meta-analysis without spin, lies or hype: These results of this meta-analysis seem to indicate that:
- currently there are several RCTs testing whether acupuncture is an effective therapy for IBS,
- all the RCTs that adequately control for placebo-effects show no effectiveness of acupuncture,
- the only RCT that yields a positive result does not make any attempt to control for placebo-effects,
- this suggests that acupuncture is a placebo,
- it also demonstrates how misleading studies with the infamous ‘A+B versus B’ design can be,
- finally, this meta-analysis seems to be a prime example of scientific misconduct with the aim of creating a positive result out of data which are, in fact, negative.
It is almost 10 years ago that Prof Kathy Sykes’ BBC series entitled ALTERNATIVE MEDICINE was aired. I had been hired by the BBC as their advisor for the programme and had tried my best to iron out the many mistakes that were about to be broadcast. But the scope for corrections turned out to be narrow and, at one stage, the errors seemed too serious and too far beyond repair to continue with my task. I had thus offered my resignation from this post. Fortunately this move led to some of my concerns being addressed after all, and they convinced me to remain in post.
The first part of the series was on acupuncture, and Kathy presented the opening scene of a young women undergoing open heart surgery with the aid of acupuncture. All the BBC had ever shown me and asked me to advise on was the text – I had never seen the images. Kathy’s text included the statement that the patient was having the surgery “with only needles to control the pain.” I had not objected to this statement in the firm belief that the images of the film would back up this extraordinary claim. As it turned out, it did not; the patient clearly had all sorts of other treatments given through intra-venous lines and, in the film, these were openly in the view of Kathy Sykes.
This overt contradiction annoyed not just me but several other people as well. One of them was Simon Singh who filed an official complaint against the BBC for misleading the public, and eventually won his case.
The notion that acupuncture can serve as an alternative to anaesthesia or other surgical conditions crops up with amazing regularity. It is important not least because is often used as a promotional tool with the implication that, IF ACUPUNCTURE CAN ACHIVE SUCH DRAMATIC EFFECTS, IT MUST BE AN INCREDIBLY USEFUL TREATMENT! It is therefore relevant to ask what the scientific evidence tells us about this issue.
This was the question we wanted to address in a recent publication. Specifically, our aim was to summarise recent systematic reviews of acupuncture for surgical conditions.
Thirteen electronic databases were searched for relevant reviews published since 2000. Data were extracted by two independent reviewers according to predefined criteria. Twelve systematic reviews met our inclusion criteria. They related to the prevention or treatment of post-operative nausea and vomiting as well as to surgical or post-operative pain. The reviews drew conclusions which were far from uniform; specifically for surgical pain the evidence was not convincing. We concluded that “the evidence is insufficient to suggest that acupuncture is an effective intervention in surgical settings.”
So, Kathy Sykes’ comment was misguided in more than just one way: firstly, the scene she described in the film did not support what she was saying; secondly, the scientific evidence fails to support the notion that acupuncture can be used as an alternative to analgesia during surgery.
This story has several positive outcomes all the same. After seeing the BBC programme, Simon Singh contacted me to learn my views on the matter. This prompted me to support his complaint against the BBC and helped him to win this case. Furthermore, it led to a co-operation and friendship which produced our book TRICK OR TREATMENT.
After a traumatic brain injury (TBI) the risk of stroke is significantly increased. Taiwanese researchers conducted a study to find out whether acupuncture can help to protect TBI patients from stroke. They used Taiwan’s National Health Insurance Research Database to conduct a retrospective cohort study of 7409 TBI patients receiving acupuncture treatment and 29,636 propensity-score-matched TBI patients without acupuncture treatment as controls. Both TBI cohorts were followed for up to two years and adjusted for immortal time to measure the incidence and adjusted hazard ratios (HRs) of new-onset stroke.
TBI patients with acupuncture treatment (4.9 per 1000 person-years) had a lower incidence of stroke compared with those without acupuncture treatment (7.5 per 1000 person-years), with a HR of 0.59 (95% CI = 0.50-0.69) after adjustment for sociodemographics, coexisting medical conditions and medications. The association between acupuncture treatment and stroke risk was investigated by sex and age group (20-44, 45-64, and ≥65 years). The probability curve with log-rank test showed that TBI patients receiving acupuncture treatment had a lower probability of stroke than those without acupuncture treatment during the follow-up period (p<0.0001).
The authors conclude that patients with TBI receiving acupuncture treatment show decreased risk of stroke compared with those without acupuncture treatment. However, this study was limited by lack of information regarding lifestyles, biochemical profiles, TBI severity, and acupuncture points used in treatments.
I want to congratulate the authors for adding the last sentence to their conclusions. There is no plausible mechanism that I can think of by which acupuncture might bring about the observed effect. This does not mean that an effect does not exist; it means, however, that it is wise to be cautious and to not jump to conclusions which later need to be revised. The simplest interpretation, by far, of the observed phenomenon is that those patients opting to have acupuncture were, on average, less ill and therefore had a lower risk of stroke.
Having said that, the findings are, I think, intriguing enough to conduct further investigations – provided they are rigorous and eliminate the confounders that prevented this study from arriving at more definitive conclusions.
One of the questions I hear regularly is ‘HOW DO THE EFFECTS OF THIS ALTERNATIVE TREATMENT COMPARE TO THOSE OF CONVENTIONAL OPTIONS’? Take acupuncture in the management of osteoarthritis, for instance. There is some encouraging evidence suggesting it might help. The most recent systematic review that I know of concluded that “acupuncture provided significantly better relief from knee osteoarthritis pain and a larger improvement in function than sham acupuncture, standard care treatment, or waiting for further treatment.” However, in order to estimate its value in practice, we ought to know whether it is as good as or perhaps even better than standard treatments. In other words, what we really want to know is its relative effectiveness.
Data to evaluate the relative effectiveness of acupuncture or other alternative therapies are hard to come by. Ideally, one would require clinical trials which provide direct comparisons between the alternative and the conventional therapy. Sadly, such studies are scarce or even non-existent. Therefore we might have to rely on more indirect evidence. A new paper could be a step in the right direction.
The aim of this systematic review was to critically evaluate existing osteoarthritis (OA) management guidelines to better understand potential issues and barriers.
A systematic review of the literature in MEDLINE published from January 1, 2000 to April 1, 2013 was performed and supplemented by bibliographic reviews, following PRISMA guidelines and a written protocol. Following initial title and abstract screening, two authors independently reviewed full-text articles; a third settled disagreements. Two independent reviewers extracted data into a standardized form. Two authors independently assessed guideline quality; three generated summary recommendations based on the extracted guideline data.
Overall, 16 articles were included in the final review. There was broad agreement on recommendations by the various organizations. For non-pharmacologic modalities, education/self-management, exercise, weight loss if overweight, walking aids as indicated, and thermal modalities were widely recommended. For appropriate patients, joint replacement was recommended; arthroscopy with debridement was not recommended for symptomatic knee OA. Pharmacologic modalities most recommended included acetaminophen/paracetamol for first line treatment and oral or topical NSAIDs for second line therapy. Intra-articular corticosteroids were generally recommended for hip and knee OA. Controversy remains about the use of acupuncture, knee braces, heel wedges, intra-articular hyaluronans, and glucosamine/chondroitin.
I think that this tells us fairly clearly that, compared to other options, acupuncture is not considered to be an overwhelmingly effective treatment for osteoarthritis by those who understand that condition best. Several other therapies seem to be preferable because the evidence is clearer and stronger and their effect sizes is larger. This, I think begs the question whether it is in the best interest of patients or indeed ethical to ignore this knowledge and recommend acupuncture as a treatment of osteoarthritis.
More generally speaking, we should always bear in mind that it is not enough proving a therapy to be effective; we usually also need to consider what else is on offer. And if you think that this is rather complex, you are, of course, correct – but wait until someone mentions issues such as safety and cost of all the relevant therapeutic options.
Advocates of alternative medicine are incredibly fond of supporting their claims with anecdotes, or ‘case-reports’ as they are officially called. There is no question, case-reports can be informative and important, but we need to be aware of their limitations.
A recent case-report from the US might illustrated this nicely. It described a 65-year-old male patient who had had MS for 20 years when he decided to get treated with Chinese scalp acupuncture. The motor area, sensory area, foot motor and sensory area, balance area, hearing and dizziness area, and tremor area were stimulated once a week for 10 weeks, then once a month for 6 further sessions.
After the 16 treatments, the patient showed remarkable improvements. He was able to stand and walk without any problems. The numbness and tingling in his limbs did not bother him anymore. He had more energy and had not experienced incontinence of urine or dizziness after the first treatment. He was able to return to work full time. Now the patient has been in remission for 26 months.
The authors of this case-report conclude that Chinese scalp acupuncture can be a very effective treatment for patients with MS. Chinese scalp acupuncture holds the potential to expand treatment options for MS in both conventional and complementary or integrative therapies. It can not only relieve symptoms, increase the patient’s quality of life, and slow and reverse the progression of physical disability but also reduce the number of relapses and help patients.
There is absolutely nothing wrong with case-reports; on the contrary, they can provide extremely valuable pointers for further research. If they relate to adverse effects, they can give us crucial information about the risks associated with treatments. Nobody would ever argue that case-reports are useless, and that is why most medical journals regularly publish such papers. But they are valuable only, if one is aware of their limitations. Medicine finally started to make swift progress, ~150 years ago, when we gave up attributing undue importance to anecdotes, began to doubt established wisdom and started testing it scientifically.
Conclusions such as the ones drawn above are not just odd, they are misleading to the point of being dangerous. A reasonable conclusion might have been that this case of a MS-patient is interesting and should be followed-up through further observations. If these then seem to confirm the positive outcome, one might consider conducting a clinical trial. If this study proves to yield encouraging findings, one might eventually draw the conclusions which the present authors drew from their single case.
To jump at conclusions in the way the authors did, is neither justified nor responsible. It is unjustified because case-reports never lend themselves to such generalisations. And it is irresponsible because desperate patients, who often fail to understand the limitations of case-reports and tend to believe things that have been published in medical journals, might act on these words. This, in turn, would raise false hopes or might even lead to patients forfeiting those treatments that are evidence-based.
It is high time, I think, that proponents of alternative medicine give up their love-affair with anecdotes and join the rest of the health care professions in the 21st century.
There are numerous types and styles of acupuncture, and the discussion whether one is better than the other has been long, tedious and frustrating. Traditional acupuncturists, for instance, individualise their approach according to their findings of pulse and tongue diagnoses as well as other non-validated diagnostic criteria. Western acupuncturists, by contrast, tend to use formula or standardised treatments according to conventional diagnoses.
This study aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice of a Chinese-born medical doctor trained in both western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups who received either standardized acupuncture or individualized acupuncture. 10 to 15 treatments based on individual symptoms were given with two treatments per week.
The main outcome measure was the area under the curve (AUC) summarizing eight weeks of daily rated pain severity measured with a visual analogue scale. No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7; standardized acupuncture 1482.9; group difference, 285.8).
The authors concluded that individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain.
But perhaps it matters whether the acupuncturist is thoroughly trained or has just picked up his/her skills during a weekend course? I am afraid not: this analysis of a total of 4,084 patients with chronic headache, lower back pain or arthritic pain treated by 1,838 acupuncturists suggested otherwise. There were no differences in success for patients treated by physicians passing through shorter (A diploma) or longer (B diploma) training courses in acupuncture.
But these are just one single trial and one post-hoc analysis of another study which, by definition, cannot be fully definitive. Fortunately, we have more evidence based on much larger numbers. This brand-new meta-analysis aimed to evaluate whether there are characteristics of acupuncture or acupuncturists that are associated with better or worse outcomes.
An existing dataset, developed by the Acupuncture Trialists’ Collaboration, included 29 trials of acupuncture for chronic pain with individual data involving 17,922 patients. The available data on characteristics of acupuncture included style of acupuncture, point prescription, location of needles, use of electrical stimulation and moxibustion, number, frequency and duration of sessions, number of needles used and acupuncturist experience. Random-effects meta-regression was used to test the effect of each characteristic on the main effect estimate of pain. Where sufficient patient-level data were available, patient-level analyses were conducted.
When comparing acupuncture to sham controls, there was little evidence that the effects of acupuncture on pain were modified by any of the acupuncture characteristics evaluated, including style of acupuncture, the number or placement of needles, the number, frequency or duration of sessions, patient-practitioner interactions and the experience of the acupuncturist. When comparing acupuncture to non-acupuncture controls, there was little evidence that these characteristics modified the effect of acupuncture, except better pain outcomes were observed when more needles were used and, from patient level analysis involving a sub-set of 5 trials, when a higher number of acupuncture treatment sessions were provided.
The authors of this meta-analysis concluded that there was little evidence that different characteristics of acupuncture or acupuncturists modified the effect of treatment on pain outcomes. Increased number of needles and more sessions appear to be associated with better outcomes when comparing acupuncture to non-acupuncture controls, suggesting that dose is important. Potential confounders include differences in control group and sample size between trials. Trials to evaluate potentially small differences in outcome associated with different acupuncture characteristics are likely to require large sample sizes.
My reading of these collective findings is that it does not matter which type of acupuncture you use nor who uses it; the clinical effects are similar regardless of the most obvious potential determinants. Hardly surprising! In fact, one would expect such results, if one considered that acupuncture is a placebo-treatment.
For those who know about the subject, this is an old hat, of course. But for many readers of this blog, it might be news: ‘Traditional’ Chinese Medicine (TCM) is not nearly as traditional as it pretends to be. In fact, it is an artefact of recent creation. The man who has been saying that for years is Professor Paul Unschuld, one of the leading sinologist worldwide and an expert who has written many books and journal articles on the subject.
During an interview given in 2004, he defined TCM as “an artificial system of health care ideas and practices generated between 1950 and 1973 by committees in the People’s Republic of China, with the aim of restructuring the vast and heterogenous heritage of Chinese traditional medicine in such a way that it fitted the principles–Marxist Maoist type democracy and modern science and technology on which the future of the PRC was to be built…[the Daoist underpinning for TCM] is incorrect for two reasons. First . . . TCM is a product of Communist China. Second, even if we were to apply the term TCM to pre-revolutionary Chinese medicine, the Daoist impact should be considered minimal.”
In a much more recent interview entitled INVENTION FROM THE FAR EAST which he gave to DER SPIEGEL (in German), he explained this in a little more detail (I have tried to translate his words as literally as possible):
What is being offered in our country to patients as TCM is a construct that was created in China on an office desk which has been altered further on its way to the West.
Already at the beginning of the 20th century, reformers and revolutionaries urged that the traditional medicine in China should be abolished and that the western form of medicine should be introduced instead. Traditional thinking was seen as backwards and it was held responsible for the oppressing superiority of the West. The introduction of Western natural sciences, medicine and technology was also thought later, after the foundation of the People’s Republic, to be essential for rendering the country competitive again. Since the traditional Chinese medicine could not be totally abolished then because it offered a living to many citizens, it was reduced to a kernel, which could be brought just about in line with the scientific orientation of the future communist society. In the 1950s and 60s, an especially appointed commission had been working on this task. The filtrate which they created from the original medical tradition was hence forward to be called TCM vis a vis foreigners.
There is little more to add, I think - perhaps just two brief after-thoughts. TCM is a most lucrative export article for China. So don’t expect Chinese officials to rid TCM of the highly marketable ‘TRADITIONAL’ label. And remember: the ‘appeal to tradition’ argument is a fallacy anyway.
