Maintenance Care is an approach whereby patients have chiropractic manipulations even when symptom-free. Thus, it is an ideal method to keep chiropractors in clover. Previous reviews concluded that evidence behind this strategy is lacking. Since then, more data have emerged. It was therefore timely to review the evidence.
Fourteen original research articles were included in the review. Maintenance Care was defined as a secondary or tertiary preventive approach, recommended to patients with previous pain episodes, who respond well to chiropractic care. Maintenance Care is applied to approximately 30% of Scandinavian chiropractic patients. Both chiropractors and patients believe in the efficacy of Maintenance Care. Four studies investigating the effect of chiropractic Maintenance Care were identified, with disparate results on pain and disability of neck and back pain. However, only one of these studies utilized all the existing evidence when selecting study subjects and found that Maintenance Care patients experienced fewer days with low back pain compared to patients invited to contact their chiropractor ‘when needed’. No studies were found on the cost-effectiveness of Maintenance Care.
The authors concluded that knowledge of chiropractic Maintenance Care has advanced. There is reasonable consensus among chiropractors on what Maintenance Care is, how it should be used, and its indications. Presently, Maintenance Care can be considered an evidence-based method to perform secondary or tertiary prevention in patients with previous episodes of low back pain, who report a good outcome from the initial treatments. However, these results should not be interpreted as an indication for Maintenance Care on all patients, who receive chiropractic treatment.
I have to admit, I have problems with these conclusions.
- Maintenance Care is not normally defined as secondary or tertitary prevention. It also includes primary prevention, which means that chiropractors recommend it for just about anyone. By definition it is long term care, that is not therapeutically necessary, but performed at regular intervals to help prevent injury and enhance quality of life. This form of care is provided after maximal therapeutic benefit is achieved, without a trial of treatment withdrawal, to prevent symptoms from returning or for those without symptoms to promote health or prevent future problems.
- I am not convinced that the evidence would be positive, even if we confined it to secondary and tertiary prevention.
To explain my last point, let’s have a look at the 4 RCT and check whether they really warrant such a relatively positive conclusion.
FIRST STUDY For individuals with recurrent or persistent non-specific low back pain (LBP), exercise and exercise combined with education have been shown to be effective in preventing new episodes or in reducing the impact of the condition. Chiropractors have traditionally used Maintenance Care (MC), as secondary and tertiary prevention strategies. The aim of this trial was to investigate the effectiveness of MC on pain trajectories for patients with recurrent or persistent LBP.
This pragmatic, investigator-blinded, two arm randomized controlled trial included consecutive patients (18–65 years old) with non-specific LBP, who had an early favorable response to chiropractic care. After an initial course of treatment, eligible subjects were randomized to either MC or control (symptom-guided treatment). The primary outcome was total number of days with bothersome LBP during 52 weeks collected weekly with text-messages (SMS) and estimated by a GEE model.
Three hundred and twenty-eight subjects were randomly allocated to one of the two treatment groups. MC resulted in a reduction in the total number of days per week with bothersome LBP compared with symptom-guided treatment. During the 12 month study period, the MC group (n = 163, 3 dropouts) reported 12.8 (95% CI = 10.1, 15.5; p = <0.001) fewer days in total with bothersome LBP compared to the control group (n = 158, 4 dropouts) and received 1.7 (95% CI = 1.8, 2.1; p = <0.001) more treatments. Numbers presented are means. No serious adverse events were recorded.
MC was more effective than symptom-guided treatment in reducing the total number of days over 52 weeks with bothersome non-specific LBP but it resulted in a higher number of treatments. For selected patients with recurrent or persistent non-specific LBP who respond well to an initial course of chiropractic care, MC should be considered an option for tertiary prevention.
SECOND STUDY Back and neck pain are associated with disability and loss of independence in older adults. Whether long‐term management using commonly recommended treatments is superior to shorter‐term treatment is unknown. This randomized clinical trial compared short‐term treatment (12 weeks) versus long‐term management (36 weeks) of back‐ and neck‐related disability in older adults using spinal manipulative therapy (SMT) combined with supervised rehabilitative exercises (SRE).
Eligible participants were ages ≥65 years with back and neck disability for ≥12 weeks. Coprimary outcomes were changes in Oswestry Disability Index (ODI) and Neck Disability Index (NDI) scores after 36 weeks. An intent‐to‐treat approach used linear mixed‐model analysis to detect between‐group differences. Secondary analyses included other self‐reported outcomes, adverse events, and objective functional measures.
THIRD STUDY A prospective single blinded placebo controlled study was conducted. To assess the effectiveness of spinal manipulation therapy (SMT) for the management of chronic nonspecific low back pain (LBP) and to determine the effectiveness of maintenance SMT in long-term reduction of pain and disability levels associated with chronic low back conditions after an initial phase of treatments. SMT is a common treatment option for LBP. Numerous clinical trials have attempted to evaluate its effectiveness for different subgroups of acute and chronic LBP but the efficacy of maintenance SMT in chronic nonspecific LBP has not been studied. Sixty patients, with chronic, nonspecific LBP lasting at least 6 months, were randomized to receive either (1) 12 treatments of sham SMT over a 1-month period, (2) 12 treatments, consisting of SMT over a 1-month period, but no treatments for the subsequent 9 months, or (3) 12 treatments over a 1-month period, along with “maintenance spinal manipulation” every 2 weeks for the following 9 months. To determine any difference among therapies, we measured pain and disability scores, generic health status, and back-specific patient satisfaction at baseline and at 1-, 4-, 7-, and 10-month intervals. Patients in second and third groups experienced significantly lower pain and disability scores than first group at the end of 1-month period (P = 0.0027 and 0.0029, respectively). However, only the third group that was given spinal manipulations (SM) during the follow-up period showed more improvement in pain and disability scores at the 10-month evaluation. In the nonmaintained SMT group, however, the mean pain and disability scores returned back near to their pretreatment level.SMT is effective for the treatment of chronic nonspecific LBP. To obtain long-term benefit, this study suggests maintenance SM after the initial intensive manipulative therapy.
FORTH STUDY Evidence indicates that supervised home exercises, combined or not with manual therapy, can be beneficial for patients with non-specific chronic neck pain (NCNP). The objective of the study is to investigate the efficacy of preventive spinal manipulative therapy (SMT) compared to a no treatment group in NCNP patients. Another objective is to assess the efficacy of SMT with and without a home exercise program.Ninety-eight patients underwent a short symptomatic phase of treatment before being randomly allocated to either an attention-group (n = 29), a SMT group (n = 36) or a SMT + exercise group (n = 33). The preventive phase of treatment, which lasted for 10 months, consisted of meeting with a chiropractor every two months to evaluate and discuss symptoms (attention-control group), 1 monthly SMT session (SMT group) or 1 monthly SMT session combined with a home exercise program (SMT + exercise group). The primary and secondary outcome measures were represented by scores on a 10-cm visual analog scale (VAS), active cervical ranges of motion (cROM), the neck disability index (NDI) and the Bournemouth questionnaire (BQ). Exploratory outcome measures were scored on the Fear-avoidance Behaviour Questionnaire (FABQ) and the SF-12 Questionnaire. Our results show that, in the preventive phase of the trial, all 3 groups showed primary and secondary outcomes scores similar to those obtain following the non-randomised, symptomatic phase. No group difference was observed for the primary, secondary and exploratory variables. Significant improvements in FABQ scores were noted in all groups during the preventive phase of the trial. However, no significant change in health related quality of life (HRQL) was associated with the preventive phase. This study hypothesised that participants in the combined intervention group would have less pain and disability and better function than participants from the 2 other groups during the preventive phase of the trial. This hypothesis was not supported by the study results. Lack of a treatment specific effect is discussed in relation to the placebo and patient provider interactions in manual therapies. Further research is needed to delineate the specific and non-specific effects of treatment modalities to prevent unnecessary disability and to minimise morbidity related to NCNP. Additional investigation is also required to identify the best strategies for secondary and tertiary prevention of NCNP.
I honestly do not think that the findings from these 4 small trials justify the far-reaching conclusion that Maintenance Care can be considered an evidence-based method… For that statement to be evidence-based, one would need to see more and better studies. Therefore, the honest conclusion, I think, is that maintenance care is not supported by sound evidence for effectiveness; as chiropractic manipulations are costly and not risk-free, its risk/benefit balance fails to be positive. Therefore, this approach cannot be recommended.
I almost forgot!
This would have been no good, after all, Charles has for decades been the most influential supporter of so-called alternative medicine (SCAM) in the UK. He is one of SCAM’s greatest proponent.
So, here is my up-dated, extended and illustrated summary of his achievements in this area.
HAPPY BIRTHDAY CHARLES!
Charles went on a journey of ‘spiritual discovery’ into the wilderness of northern Kenya. His guru and guide at the time was Laurens van der Post (later discovered to be a fraud and compulsive fantasist and to have fathered a child with a 14-year old girl entrusted to him during a sea voyage).
Van der Post wanted to awake Charles’ mind and attune it to the vitalistic ideas of Carl Jung’s ‘collective unconscious’, and it is this belief in vitalism that provides the crucial link to alternative medicine: virtually every form of alternative therapies is based on the assumption that some sort of vital force exists. Charles was so taken by van der Post that he made him the godfather of Prince William. After Post’s death, he established an annual lecture in his honour (the lecture series was discontinued after Van der Post was discovered to be a fraud).
Some time in the 1970s, Charles met Jimmy Saville and befriended him. Apparently, Saville later advised Charles on several occasions in various health-related matters.
Throughout the 1980s, Charles lobbied for the statutory regulation of chiropractors and osteopaths in the UK. In 1993, this finally became reality. These two SCAM professions are to this day the only ones regulated by statute in the UK.
Osteopathy has strong Royal links: Prince Charles is the President of the GOsC; Princess Diana was the President of the GCRO; and Princess Anne is the patron of the British School of Osteopathy (statement dated 2011).
In 1982, Prince Charles was elected as President of the British Medical Association (BMA) and promptly challenged the medical orthodoxy by advocating alternative medicine. In a speech at his inaugural dinner as President, the Prince lectured the medics: ‘Through the centuries healing has been practised by folk healers who are guided by traditional wisdom which sees illness as a disorder of the whole person, involving not only the patient’s body, but his mind, his self-image, his dependence on the physical and social environment, as well as his relation to the cosmos.’ The BMA-officials ordered a full report on alternative medicine which promptly condemned this area as implausible nonsense.
Six years later, a second report, entitled Complementary Medicine – New Approaches to Good Practice, heralded an astonishing about-turn stating that: “the demand for non-conventional therapies had become so pressing that organised medicine in Britain could no longer ignore its contribution”. At the same time, however, the BMA set in motion a further chapter in the history of SCAM by insisting that it was “unacceptable” to allow the unrestricted practice of non-conventional therapies, irrespective of training or experience.
In 1993, Charles founded his lobby group which, after being re-named several times, ended up being called the ‘Foundation for Integrated Health’ (FIH). It was closed down in 2010 amidst allegations of money laundering and fraud. Its chief executive, George Gray, was later convicted and went to jail. The FIH had repeatedly been a little economical with the truth.
In 2000, Charles wrote an open letter to The Times stating that…It makes good sense to evaluate complementary and alternative therapies. For one thing, since an estimated £1.6 billion is spent each year on them, then we want value for our money. The very popularity of the non-conventional approaches suggests that people are either dissatisfied with their orthodox treatment, or they find genuine relief in such therapies. Whatever the case, if they are proved to work, they should be made more widely available on the NHS…But there remains the cry from the medical establishment of “where’s the proof?” — and clinical trials of the calibre that science demands cost money…The truth is that funding in the UK for research into complementary medicine is pitiful…So where can funding come from?…Figures from the department of complementary medicine at the University of Exeter show that less than 8p out of every £100 of NHS funds for medical research was spent on complementary medicine. In 1998-99 the Medical Research Council spent no money on it at all, and in 1999 only 0.05 per cent of the total research budget of UK medical charities went to this area…
In 2001, Charles worked on plans to help build a model hospital of integrated medicine. It was to train doctors to combine conventional medicine and alternative treatments, such as homeopathy, Ayurvedic medicine and acupuncture, and was to have up to 100 beds. The prince’s intervention marked the culmination of years of campaigning by him for the NHS to assign a greater role to alternative medicine. Teresa Hale, founder of the Hale Clinic in London, said: “Twenty-five years ago people said we were quacks. Now several branches, including homeopathy, acupuncture and osteopathy, have gained official recognition.” The proposed hospital, which was due to open in London in 2003/4, was to be overseen by Mosaraf Ali, who runs the Integrated Medical Centre (IMC) in London. But the hospital never materialised.
This might be due to Mosaraf Ali falling in disrepute: Raj Bathija, 69 and from India, went for a massage at the clinic of Dr Mosaraf Ali and his brother Imran in 2005 after suffering from two strokes. However, he claims that shortly after the treatment, his legs became pale and discoloured. Four days afterwards, Mr Bathija was admitted to hospital, where he had to have both legs amputated below the knee due to a shortage of blood. According to Mr Bathija, Dr Ali and his brother were negligent in that they failed to diagnose his condition and neglected to advise him to go to hospital. His daughter Shibani said: “My father was in a wheelchair but was making progress with his walking. He hoped he might become a bit more independent. With the amputations, that’s all gone.” Dr Ali was sued (if anyone knows the outcome of this case, please let me know).
At the age of 53, Mrs Parker Bowles went on a trek to the Himalayas to ‘re-energise’ her spirits and encourage her to give up smoking. She was in a party of 12 accompanied by the Prince of Wales’s favourite health guru, Dr Mosaraf Ali. Mrs Parker Bowles subsequently became a regular visitor to Dr Ali’s London practice where she has been encouraged to take up yoga both to combat her back pain and to help her give up smoking.
In the same year, Charles published an editorial in the BMJ promoting his ideas around integrative medicine. Its title: THE BEST OF BOTH WORLDS.
In 2003, Prince Charles’ FIH launched a five-year plan which outlined how to improve access to alternative therapies.
In 2004, Charles publicly supported the Gerson diet as a treatment for cancer and Prof Baum, an eminent oncologist, was invited to respond in an open letter to the British Medical Journal: …Over the past 20 years I have treated thousands of patients with cancer and lost some dear friends and relatives to this dreaded disease…The power of my authority comes with knowledge built on 40 years of study and 25 years of active involvement in cancer research. Your power and authority rest on an accident of birth. I don’t begrudge you that authority but I do beg you to exercise your power with extreme caution when advising patients with life-threatening diseases to embrace unproven therapies.
In 2005, the ‘Smallwood-Report’ was published; it had been commissioned by Charles and paid for by Dame Shirley Porter to inform health ministers. It stated that up to 480 million pounds could be saved, if one in 10 family doctors offered homeopathy as an “alternative” to standard drugs for asthma. Savings of up to 3.5 billion pounds could be achieved by offering spinal manipulation rather than drugs to people with back pain. Because I had commented on this report, Prince Charles’ first private secretary asked my vice chancellor to investigate my alleged indiscretion; even though I was found to be not guilty of any wrong-doing, all local support at Exeter stopped which eventually led to my early retirement. ITV later used this incident in a film entitled THE MEDDLING PRINCE, I later published a full account of this sad story in my memoir.
In a 2006 speech, Prince Charles told the World Health Organisation in Geneva that alternative medicine should have a more prominent place in health care and urged every country to come up with a plan to integrate conventional and alternative medicine into the mainstream. But British science struck back. Anticipating Prince Charles’s sermon in Geneva, 13 of Britain’s most eminent physicians and scientists wrote an “Open Letter” which expressed concern over “ways in which unproven or disproved treatments are being encouraged for general use in Britain’s National Health Service.” The signatories argued that “it would be highly irresponsible to embrace any medicine as though it were a matter of principle.”
In 2008, The Times published my letter asking the FIH to withdraw two guides promoting alternative medicine, stating: “the majority of alternative therapies appear to be clinically ineffective, and many are downright dangerous.” A speaker for the FIH countered the criticism by stating: “We entirely reject the accusation that our online publication Complementary Healthcare: A Guide contains any misleading or inaccurate claims about the benefits of complementary therapies. On the contrary, it treats people as adults and takes a responsible approach by encouraging people to look at reliable sources of information… so that they can make informed decisions. The foundation does not promote complementary therapies.”
In 2009, the Prince held talks with the health Secretary to persuade him to introduce safeguards amid a crackdown by the EU that could prevent anyone who is not a registered health practitioner from selling remedies. This, it seems, was yet another example of Charles’ disregard of his constitutional role.
In the same year, Charles urged the government to protect alternative medicine because “we fear that we will see a black market in herbal products”, as Dr Michael Dixon (LVO,2015; OBE 2001), then medical director of Charles’ FIH, put it.
In 2009, the health secretary wrote to the prince suggesting a meeting on the possibility of a study on integrating complementary and conventional healthcare approaches in England. The prince had written to Burnham’s predecessor, Alan Johnson, to demand greater access to complementary therapies in the NHS alongside conventional medicine. The prince told him that “despite waves of invective over the years from parts of the medical and scientific establishment” he continued to lobby “because I cannot bear people suffering unnecessarily when a complementary approach could make a real difference”. He opposed “large and threatened cuts” in the funding of homeopathic hospitals and their possible closure. He complained that referrals to the Royal London homeopathic hospital were increasing “until what seems to amount to a recent ‘anti-homeopathic campaign’”. He warned against cuts despite “the fact that these homeopathic hospitals deal with many patients with real health problems who otherwise would require treatment elsewhere, often at greater expense”.
In 2009, it was announced that the ‘College of Integrated Medicine’ (the name was only later changed to ‘College of Medicine’, see below) was to have a second base in India. An Indian spokesman commented: “The second campus of the Royal College will be in Bangalore. We have already proposed the setting up of an All India Institute of Integrated Medicine to the Union health ministry. At a meeting in London last week with Prince Charles, we finalized the project which will kick off in July 2010”.
In 2010, Charles publicly stated that he was proud to be perceived as ‘an enemy of the enlightenment’.
In 2010, ‘Republic’ filed an official complaint about FIH alleging that its trustees allowed the foundation’s staff to pursue a public “vendetta” against a prominent critic of the prince’s support for complementary medicines. It also suggested that the imminent closure of Ernst’s department may be partly down to the charity’s official complaint about him after he publicly attacked its draft guide to complementary medicines as “outrageous and deeply flawed”.
In 2010, former fellows of Charles’ disgraced FIH launched a new organisation, The College of Medicine’ supporting the use of integrated treatments in the NHS. One director of the college is Michael Dixon, a GP in Cullompton, formerly medical director of the Foundation for Integrated Health. My own analysis of the activities of the new college leaves little doubt that it is promoting quackery.
In 2011, after the launch of Charles’ range of herbal tinctures, I had the audacity to publicly criticise Charles for selling the Duchy Herbals detox tincture which I named ‘Dodgy Originals Detox Tincture’.
In 2011, Charles forged a link between ‘The College of Medicine’ and an Indian holistic health centre (see also above). The collaboration was reported to include clinical training to European and Western doctors in ayurveda and homoeopathy and traditional forms of medicine to integrate them in their practice. The foundation stone for the extended campus of the Royal College known as the International Institution for Holistic and Integrated Medicine was laid by Dr Michael Dixon in collaboration with the Royal College of Medicine.
In 2012, Charles was nominated for ‘THE GOLDEN DUCK AWARD’ for his achievements in promoting quackery. However, Andrew Wakefield beat him to it; Charles certainly was a deserving runner-up.
In 2013, Charles called for society to embrace a broader and more complex concept of health. In his article he described a vision of health that includes the physical and social environment, education, agriculture and architecture.
In 2013, Charles’ Highgrove enterprise offered ‘baby-hampers’ for sale at £195 a piece and made a range of medicinal claims for the products it contained. As these claims were not supported by evidence, there is no way to classify them other than quackery.
By 2013, the ‘Association of Osteomyologists’ were seeking to become regulated by statute, with the help of Prince Charles as their patron. The chairman and founder of this organisation was knighted for services to alternative medicine. Osteomyologists encourage the use of techniques including cranio-sacral therapy and claim that “we all know that Colleges, Institutions, and Medical Practitioners, are brain washed from the very outset into believing that their discipline is the only way to go.”
In November 2013, Charles invited alternative medicine proponents from across the world, including Dean Ornish, Michael Dixon, chair of College of Medicine, UK and Issac Mathai of Soukya Foundation, Bangalore, to India for a ‘brain storm’ and a subsequent conference on alternative medicine. The prince wanted the experts to collaborate and explore the possibilities of integrating different systems of medicines and to better the healthcare delivery globally, one of the organisers said.
In June 2014, BBC NEWS published the following 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. On this blog, I have pointed out that the research in question was fatally flawed and that Charles, once again, overstepped the boundaries of his constitutional role.
In 2015, two books were published which are relevant in this context. My memoir A SCIENTIST IN WONDERLAND recounts most of my dealings with Charles and his sycophants, including how an intervention from his first private secretary eventually led to the closure of my department. The book by Catherine Meyer CHARLES, THE HEART OF A KING is far less critical about our heir to the throne; it nevertheless severely criticises his stance on alternative medicine.
In October 2015, the Guardian obtained the infamous “black spider memos” which revealed that Charles had repeatedly lobbied politicians in favour of alternative medicine (see also above).
In 2016, speaking at a global leaders summit on antimicrobial resistance, Prince Charles warned that Britain faced a “potentially disastrous scenario” because of the “overuse and abuse” of antibiotics. The Prince explained that he had switched to organic farming on his estates because of the growing threat from antibiotic resistance and now treats his cattle with homeopathic remedies rather than conventional medication. “As some of you may be aware, this issue has been a long-standing and acute concern to me,” he told delegates from 20 countries “I have enormous sympathy for those engaged in the vital task of ensuring that, as the world population continues to increase unsustainably and travel becomes easier, antibiotics retain their availability to overcome disease… It must be incredibly frustrating to witness the fact that antibiotics have too often simply acted as a substitute for basic hygiene, or as it would seem, a way of placating a patient who has a viral infection or who actually needs little more than patience to allow a minor bacterial infection to resolve itself.”
In 2017, the ‘College of Medicine’ mentioned above was discretely re-named ‘College of Medicine and Integrated Health’
In the same year, Charles declared that he will open a centre for alternative medicine in the recently purchased Dumfries House in Scotland. Currently, the College of Medicine and Integrated Health is offering two-day Foundation Courses at this iconic location. Gabriel Chiu, a US celebrity cosmetic and reconstructive surgeon, and his wife Christine, joined the Prince of Wales as he opened the integrated health and wellbeing centre on the Dumfries House Estate in East Ayrshire in 2019. As he unveiled a plaque at the event, Prince Charles said: “I’m so glad that all of you have been able to get here today, particularly because I could not be more proud to see the opening of this new integrated health centre at Dumfries House. It’s something I’ve been wanting to do for the last 35 years. I’m also so proud of all the team at Dumfries House who built it, an all in-house team.
“To reach this point where we can now offer a range of social prescribing opportunities is enormously encouraging and I hope it will be able to make some difference to a lot of the health issues that exist in this area.”
Also in 2017, ‘Country News’ published an article about our heir to the throne stating that Prince of Wales has revealed he uses homeopathic treatments for animals on his organic farm at Highgrove to help reduce reliance on antibiotics, the article stated. He said his methods of farming tried wherever possible to ‘‘go with the grain of nature’’ to avoid dependency on antibiotics, pesticides and other forms of chemical intervention.
In 2018, The Prince of Wales accompanied the Prime Minister of India, Narendra Modi, to the Science Museum in London, and praised Asian medicine practices. The heir to the throne and the Indian Prime Minister then jointly unveiled a plaque for the UK’s first centre of excellence for Indian traditional medicine.
In the same year, it was revealed that UK farmers are being taught how to treat their livestock with homeopathy “by kind permission of His Royal Highness, The Prince Of Wales”
In 2019, the Faculty of Homeopathy announced that His Royal Highness The Prince of Wales had accepted to become Patron of the Faculty of Homeopathy. Dr Gary Smyth, President of the Faculty of Homeopathy comments, “As the Faculty celebrates its 175th anniversary this year, it is an enormous honour for us to receive the Patronage of His Royal Highness The Prince of Wales and I am delighted to announce this news today.” Charles’ move amazed observers who saw it as a deliberate protest against the discontinuation of reimbursement of homeopathy by the NHS.
In 2019, Prince Charles said that yoga had “proven beneficial effects on both body and mind,” and has “tremendous social benefits” that help build “discipline, self-reliance and self-care.”
So again, Happy Birthday Your Royal Highness – and please don’t forget: it’s not too late to start doing good in the realm of healthcare by supporting good science, critical thinking and evidence-based medicine.
The World Federation of Chiropractic (WFC) claim to have been at the forefront of the global development of chiropractic. Representing the interests of the profession in over 90 countries worldwide, the WFC has advocated, defended and promoted the profession across its 7 world regions. Now, the WFC have formulated 20 principles setting out who they are, what they stand for, and how chiropractic as a global health profession can, in their view, impact on nations so that populations can thrive and reach their full potential. Here are the 20 principles (in italics followed by some brief comments by me in normal print):
1. We envision a world where people of all ages, in all countries, can access the benefits of chiropractic.
That means babies and infants! What about the evidence?
2. We are driven by our mission to advance awareness, utilization and integration of chiropractic internationally.
One could almost suspect that the drive is motivated by misleading the public about the risks and benefits of spinal manipulation for financial gain.
3. We believe that science and research should inform care and policy decisions and support calls for wider access to chiropractic.
If science and research truly did inform care, it would soon be chiropractic-free.
4. We maintain that chiropractic extends beyond the care of patients to the promotion of better health and the wellbeing of our communities.
The best example to show that this statement is a politically correct platitude is the fact that so many chiropractors are (educated to become) convinced that vaccinations are undesirable or harmful.
5. We champion the rights of chiropractors to practice according to their training and expertise.
I am not sure what this means. Could it mean that they must practice according to their training and expertise, even if both fly in the face of the evidence?
6. We promote evidence-based practice: integrating individual clinical expertise, the best available evidence from clinical research, and the values and preferences of patients.
So far, I have seen little to convince me that chiropractors care a hoot about the best available evidence and plenty to fear that they supress it, if it does not enhance their business.
7. We are committed to supporting our member national associations through advocacy and sharing best practices for the benefit of patients and society.
Much more likely for the benefit of chiropractors, I suspect.
8. We acknowledge the role of chiropractic care, including the chiropractic adjustment, to enhance function, improve mobility, relieve pain and optimize wellbeing.
Of course, you have to pretend that chiropractic adjustments (of subluxations) are useful. However, evidence would be better than pretence.
9. We support research that investigates the methods, mechanisms, and outcomes of chiropractic care for the benefit of patients, and the translation of research outcomes into clinical practice.
And if it turns out to be to the detriment of the patient? It seems to me that you seem to know the result of the research before you started it. That does not bode well for its reliability.
10. We believe that chiropractors are important members of a patient’s healthcare team and that interprofessional approaches best facilitate optimum outcomes.
Of course you do believe that. Why don’t you show us some evidence that your belief is true?
11. We believe that chiropractors should be responsible public health advocates to improve the wellbeing of the communities they serve.
Of course you do believe that. But, in fact, many chiropractors are actively undermining the most important public health measure, vaccination.
12. We celebrate individual and professional diversity and equality of opportunity and represent these values throughout our Board and committees.
What you should be celebrating is critical assessment of all chiropractic concepts. This is the only way to make progress and safeguard the interests of the patient.
13. We believe that patients have a fundamental right to ethical, professional care and the protection of enforceable regulation in upholding good conduct and practice.
The truth is that many chiropractors violate medical ethics on a daily basis, for instance, by not obtaining fully informed consent.
14. We serve the global profession by promoting collaboration between and amongst organizations and individuals who support the vision, mission, values and objectives of the WFC.
Yes, those who support your vision, mission, values and objectives are your friends; those who dare criticising them are your enemies. It seems far from you to realise that criticism generates progress, perhaps not for the WFC, but for the patient.
15. We support high standards of chiropractic education that empower graduates to serve their patients and communities as high value, trusted health professionals.
For instance, by educating students to become anti-vaxxers or by teaching them obsolete concepts such as adjustment of subluxation?
16. We believe in nurturing, supporting, mentoring and empowering students and early career chiropractors.
You are surpassing yourself in the formulation of platitudes.
17. We are committed to the delivery of congresses and events that inspire, challenge, educate, inform and grow the profession through respectful discourse and positive professional development.
You are surpassing yourself in the formulation of platitudes.
18. We believe in continuously improving our understanding of the biomechanical, neurophysiological, psychosocial and general health effects of chiropractic care.
Even if there are no health effects?!?
19. We advocate for public statements and claims of effectiveness for chiropractic care that are honest, legal, decent and truthful.
Advocating claims of effectiveness in the absence of proof of effectiveness is neither honest, legal, decent or truthful, in my view.
20. We commit to an EPIC future for chiropractic: evidence-based, people-centered, interprofessional and collaborative.
And what do you propose to do with the increasing mountain of evidence suggesting that your spinal adjustments are not evidence-based as well as harmful to the health and wallets of your patients?
What do I take out of all this? Not a lot!
Perhaps mainly this: the WFC is correct when stating that, in the interests of the profession in over 90 countries worldwide, the WFC has advocated, defended and promoted the profession across its 7 world regions. What is missing here is a small but important addition to the sentence: in the interests of the profession and against the interest of patients, consumers or public health in over 90 countries worldwide, the WFC has advocated, defended and promoted the profession across its 7 world regions.
There is a long-standing debate on the question whether the use of homeopathy saves money. Homeopathy fans usually insist that it does. Even the Smallwood report commissioned by Prince Charles claimed that the NHS could save pots of money, if GPs only used more homeopathy.
And it is true, of course: on average homeopathics are cheaper than drugs. Therefore, replacing drugs with homeopathics would be a cost-saving. But, in healthcare, we cannot think like this; if we did, this logic would tell us that not doing anything at all would be even cheaper.
Somehow, we need to factor into the equation the effectiveness of the interventions that we are evaluating. The way to do this is to conduct proper cost-effectiveness analyses. And the reliable evidence from such assessments fails to confirm the notion that homeopathy might save us money.
So, why did I entitle this post HOW TO SAVE MONEY WITH HOMEOPATHY?
Because, it is true: you can save money, if you adhere to my instructions!
If you or a friend of yours are ill and therefore tempted by the numerous claims of homeopaths, please follow this simple step by step procedure:
- Go to your library, find a reliable book (I recommend this one), inform yourself what homeopathy truly is and absorb in the fact that a typical homeopathic remedy contains exactly zero active molecules.
- Read a bit further and check out what the best evidence from rigorous clinical trials tells us about the effectiveness of homeopathy.
- Go to a pharmacy that specialises in homeopathic products.
- Ask the pharmacist which homeopathic remedies she recommends for the ailment you suffer from.
- Ask the pharmacist to tell you what these would cost.
- Tell the pharmacist what you have just learnt about the evidence.
- Ask her kindly not to mislead customers in future.
- Go home.
- Repeat 3 – 8 as often as you can.
I think you have to agree that by following my instructions, you have saved exactly the amount of money that the pharmacist quoted.
And for those for whom this advice comes too late, because they already have at home a selection of homeopathic remedies, I have the following cost-saving trick: use them for sweetening your tea or coffee. This saves you the cost of buying sugar – every little bit helps!
I have reported about the French activities against homeopathy before (see here and here). Yesterday, this article brought considerable more clarity into the situation. Here is my (not entirely literal) translation and below the French original:
Unsurprisingly, the French health regulator (HAS) has voted on Wednesday with a very large majority (only one vote against) for the discontinuation of the reimbursement of homeopathic products. This decision, which is not denied by the health ministry, will be officially announced this Friday morning by the president of the authority, Prof Dominique Le Guludec, during a press conference. Then it will be up to the health minister, Agnès Buzyn, to decide or not on the discontinuation of reimbursement.
‘I will follow the advice of the health authority‘ the health minister declared only recently. This advice is the direct consequence of a first meeting of the commission which took place in Mid May and gave an opinion that already went into that direction. The laboratories concerned had the right to be heard and to present their view. Obviously this was not convincing.
Sans surprise, la Commission de la transparence de la Haute autorité de santé a voté ce mercredi à la très grande majorité (une seule voix contre) le déremboursement des produits homéopathiques. Cette décision, que ne dément pas le ministère de la Santé, sera annoncée officiellement vendredi matin par la présidente de la Haute Autorité de santé, la professeur Dominique Le Guludec, au cours d’une conférence de presse. A charge ensuite à la ministre de la Santé, Agnès Buzyn, de décider ou non ce déremboursement.
«Je me tiendrai à l’avis de la Haute Autorité de santé», a encore récemment déclarée la ministre. Cet avis est la conséquence directe d’une première réunion, qui s’est tenue à la mi mai, de la dite Commission, qui avait alors rendu un avis transitoire, allant clairement dans ce sens. Comme le stipule le processus, les laboratoires concernées avaient le droit d’être entendus et de se défendre. Manifestement, ces derniers n’ont pas convaincus.
A new paper reminds us that so-called alternative medicine (SCAM) has been increasing in the United States and around the world, particularly at medical institutions known for providing rigorous evidence-based care. The use of SCAM may cause harm to patients through interactions with prescribed medications or by patients choosing to forego evidence-based care. SCAM may also put financial strain on patients as most SCAM expenditures are paid out-of-pocket.
Despite these drawbacks, patients continue to use SCAM due to a range of reasons, e.g. media promotion of SCAM therapies, dissatisfaction with conventional healthcare, a desire for more holistic care. Given the increasing demand for SCAM, many medical institutions now offer SCAM services. Several leaders of SCAM centres based at a highly respected academic medical institution have publicly expressed anti-vaccination views, and non-evidence-based philosophies run deep within SCAM.
Although there are financial incentives for institutions to provide SCAM, it is important to recognize that this legitimizes SCAM and may cause harm to patients. The poor regulation of SCAM allows for the continued distribution of products and services that have not been rigorously tested for safety and efficacy.
As I have tried to point out many times, the potential for harm caused by the increasing integration of SCAM can thus be summarised as follows:
- direct harm due to adverse effects such as toxicity of an herbal remedy, stroke after chiropractic manipulation, pneumothorax after acupuncture;
- direct harm through the use of bogus diagnostic techniques;
- direct harm by using materials from endangered species;
- indirect harm through incompetent advice such as recommendation not to immunize or discontinue prescribed medications;
- neglect due to using SCAM instead of an effective therapy for a serious condition;
- harm due to medicalising trivial states of reduced well-being;
- financial harm due to the costs of SCAM;
- harm through making a mockery of evidence-based medicine;
- harm caused by undermining rational thinking in the society at large;
- harm caused by inhibiting medical progress and research.
In case you see other ways in which SCAM can cause harm, please let me know by posting a comment.
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!
Robert Verkerk, Executive & scientific director, Alliance for Natural Health (ANH), seems to adore me (maybe that’s why I kept this post for Valentine’s Day?). In 2006, he published this article about me (it is lengthy, and I therefore shortened a bit, but feel free to study it in its full beauty):
START OF QUOTE
PROFESSOR EDZARD ERNST, the UK’s first professor of complementary medicine, gets lots of exposure for his often overtly negative views on complementary medicine. He’s become the media’s favourite resource for a view on this controversial subject…
The interesting thing about Prof Ernst is that he seems to have come a long way from his humble beginnings as a recipient of the therapies that he now seems so critical of. Profiled by Geoff Watts in the British Medical Journal, the Prof tells us: ‘Our family doctor in the little village outside Munich where I grew up was a homoeopath. My mother swore by it. As a kid I was treated homoeopathically. So this kind of medicine just came naturally. Even during my studies I pursued other things like massage therapy and acupuncture. As a young doctor I had an appointment in a homeopathic hospital, and I was very impressed with its success rate. My boss told me that much of this success came from discontinuing main stream medication. This made a big impression on me.’ (BMJ Career Focus 2003; 327:166; doi:10.1136/bmj.327.7425.s166)…
After his early support for homeopathy, Professor Ernst has now become, de facto, one of its main opponents. Robin McKie, science editor for The Observer (December 18, 2005) reported Ernst as saying, ‘Homeopathic remedies don’t work. Study after study has shown it is simply the purest form of placebo. You may as well take a glass of water than a homeopathic medicine.’ Ernst, having done the proverbial 180 degree turn, has decided to stand firmly shoulder to shoulder with a number of other leading assailants of non-pharmaceutical therapies, such as Professors Michael Baum and Jonathan Waxman. On 22 May 2006, Baum and twelve other mainly retired surgeons, including Ernst himself, bandied together and co-signed an open letter, published in The Times, which condemned the NHS decision to include increasing numbers of complementary therapies…
As high profile as the Ernsts, Baums and Waxmans of this world might be—their views are not unanimous across the orthodox medical profession. Some of these contrary views were expressed just last Sunday in The Sunday Times (Lost in the cancer maze, 10 December 2006)…
The real loser in open battles between warring factions in healthcare could be the consumer. Imagine how schizophrenic you could become after reading any one of the many newspapers that contains both pro-natural therapy articles and stinging attacks like that found in this week’s Daily Mail. But then again, we may misjudge the consumer who is well known for his or her ability to vote with the feet—regardless. The consumer, just like Robert Sandall, and the millions around the world who continue to indulge in complementary therapies, will ultimately make choices that work for them. ‘Survival of the fittest’ could provide an explanation for why hostile attacks from the orthodox medical community, the media and over-zealous regulators have not dented the steady increase in the popularity of alternative medicine.
Although we live in a technocratic age where we’ve handed so much decision making to the specialists, perhaps this is one area where the might of the individual will reign. Maybe the disillusionment many feel for pharmaceutically-biased healthcare is beginning to kick in. Perhaps the dictates from the white coats will be overruled by the ever-powerful survival instinct and our need to stay in touch with nature, from which we’ve evolved.
END OF QUOTE
Elsewhere, Robert Verkerk even called me the ‘master trickster of evidence-based medicine’ and stated that Prof Ernst and his colleagues appear to be evaluating the ‘wrong’ variable. As Ernst himself admitted, his team are focused on exploring only one of the variables, the ‘specific therapeutic effect’ (Figs 1 and 2). It is apparent, however, that the outcome that is of much greater consequence to healthcare is the combined effect of all variables, referred to by Ernst as the ‘total effect’ (Fig 1). Ernst does not appear to acknowledge that the sum of these effects might differ greatly between experimental and non-experimental situations.
Adding insult to injury, Ernst’s next major apparent faux pas involves his interpretation, or misinterpretation, of results. These fundamental problems exist within a very significant body of Prof Ernst’s work, particularly that which has been most widely publicised because it is so antagonistic towards healing cultures that have in many cases existed and evolved over thousands of years.
By example, a recent ‘systematic review’ of individualised herbal medicine undertaken by Ernst and colleagues started with 1345 peer-reviewed studies. However, all but three (0.2%) of the studies (RCTs) were rejected. These three RCTs in turn each involved very specific types of herbal treatment, targeting patients with IBS, knee osteoarthritis and cancer, the latter also undergoing chemotherapy, respectively. The conclusions of the study, which fuelled negative media worldwide, disconcertingly extended well beyond the remit of the study or its results. An extract follows: “Individualised herbal medicine, as practised in European medical herbalism, Chinese herbal medicine and Ayurvedic herbal medicine, has a very sparse evidence base and there is no convincing evidence that it is effective in any [our emphasis] indication. Because of the high potential for adverse events and negative herb-herb and herb-drug interactions, this lack of evidence for effectiveness means that its use cannot be recommended (Postgrad Med J 2007; 83: 633-637).
Robert Verkerk has recently come to my attention again – as the main author of a lengthy report published in December 2018. Its ‘Executive Summary’ makes the following points relevant in the context of this blog (the numbers in his text were added by me and refer to my comments below):
- This position paper proposes a universal framework, based on ecological and sustainability principles, aimed at allowing qualified health professionals (1), regardless of their respective modalities (disciplines), to work collaboratively and with full participation of the public in efforts to maintain or regenerate health and wellbeing. Accordingly, rather than offering ‘fixes’ for the NHS, the paper offers an approach that may significantly reduce the NHS’s current and growing disease burden that is set to reach crisis point given current levels of demand and funding.
- A major factor driving the relentlessly rising costs of the NHS is its over-reliance on pharmaceuticals (2) to treat a variety of preventable, chronic disorders. These (3) are the result — not of infection or trauma — but rather of our 21st century lifestyles, to which the human body is not well adapted. The failure of pharmaceutically-based approaches to slow down, let alone reverse, the dual burden of obesity and type 2 diabetes means wider roll-out of effective multi-factorial approaches are desperately needed (4).
- The NHS was created at a time when infectious diseases were the biggest killers (5). This is no longer the case, which is why the NHS must become part of a wider system that facilitates health regeneration or maintenance. The paper describes the major mechanisms underlying these chronic metabolic diseases, which are claiming an increasingly large portion of NHS funding. It identifies 12 domains of human health, many of which are routinely thrown out of balance by our contemporary lifestyles. The most effective way of treating lifestyle disorders is with appropriate lifestyle changes that are tailored to individuals, their needs and their circumstances. Such approaches, if appropriately supported and guided, tend to be far more economical and more sustainable as a means of maintaining or restoring people’s health (6).
- A sustainable health system, as proposed in this position paper, is one in which the individual becomes much more responsible for maintaining his or her own health and where more effort is invested earlier in an individual’s life prior to the downstream manifestation of chronic, degenerative and preventable diseases (7). Substantially more education, support and guidance than is typically available in the NHS today will need to be provided by health professionals (1), informed as necessary by a range of markers and diagnostic techniques (8). Healthy dietary and lifestyle choices and behaviours (9) are most effective when imparted early, prior to symptoms of chronic diseases becoming evident and before additional diseases or disorders (comorbidities) have become deeply embedded.
- The timing of the position paper’s release coincides not only with a time when the NHS is in crisis, but also when the UK is deep in negotiations over its extraction from the European Union (EU). The paper includes the identification of EU laws that are incompatible with sustainable health systems, that the UK would do well to reject when the time comes to re-consider the British statute books following the implementation of the Great Repeal Bill (10).
- This paper represents the first comprehensive attempt to apply sustainability principles to the management of human health in the context of our current understanding of human biology and ecology, tailored specifically to the UK’s unique situation. It embodies approaches that work with, rather than against, nature (11). Sustainability principles have already been applied successfully to other sectors such as energy, construction and agriculture.
- It is now imperative that the diverse range of interests and specialisms (12) involved in the management of human health come together. We owe it to future generations to work together urgently, earnestly and cooperatively to develop and thoroughly evaluate new ways of managing and creating health in our society. This blueprint represents a collaborative effort to give this process much needed momentum.
My very short comments:
- I fear that this is meant to include SCAM-practitioners who are neither qualified nor skilled to tackle such tasks.
- Dietary supplements (heavily promoted by the ANH) either have pharmacological effects, in which case they too must be seen as pharmaceuticals, or they are useless, in which case we should not promote them.
- I think ‘some of these’ would be more correct.
- Multifactorial yes, but we must make sure that useless SCAMs are not being pushed in through the back-door. Quackery must not be allowed to become a ‘factor’.
- Only, if we discount cancer and arteriosclerosis, I think.
- SCAM-practitioners have repeatedly demonstrated to be a risk to public health.
- All we know about disease prevention originates from conventional medicine and nothing from SCAM.
- Informed by…??? I would prefer ‘based on evidence’ (evidence being one term that the report does not seem to be fond of).
- All healthy dietary and lifestyle choices and behaviours that are backed by good evidence originate from and are part of conventional medicine, not SCAM.
- Do I detect the nasty whiff a pro-Brexit attitude her? I wonder what the ANH hopes for in a post-Brexit UK.
- The old chestnut of conventional medicine = unnatural and SCAM = natural is being warmed up here, it seems to me. Fallacy galore!
- The ANH would probably like to include a few SCAM-practitioners here.
Call me suspicious, but to me this ANH-initiative seems like a clever smoke-screen behind which they hope to sell their useless dietary supplements and homeopathic remedies to the unsuspecting British public. Am I mistaken?
Chronic back pain is often a difficult condition to treat. Which option is best suited?
A review by the US ‘Agency for Healthcare Research and Quality’ (AHRQ) focused on non-invasive nonpharmacological treatments for chronic pain. The following therapies were considered:
- mind-body practices,
- psychological therapies,
- multidisciplinary rehabilitation,
- mindfulness practices,
- manual therapies,
- physical modalities,
Here, I want to share with you the essence of the assessment of spinal manipulation:
- Spinal manipulation was associated with slightly greater effects than sham manipulation, usual care, an attention control, or a placebo intervention in short-term function (3 trials, pooled SMD -0.34, 95% CI -0.63 to -0.05, I2=61%) and intermediate-term function (3 trials, pooled SMD -0.40, 95% CI -0.69 to -0.11, I2=76%) (strength of evidence was low)
- There was no evidence of differences between spinal manipulation versus sham manipulation, usual care, an attention control or a placebo intervention in short-term pain (3 trials, pooled difference -0.20 on a 0 to 10 scale, 95% CI -0.66 to 0.26, I2=58%), but manipulation was associated with slightly greater effects than controls on intermediate-term pain (3 trials, pooled difference -0.64, 95% CI -0.92 to -0.36, I2=0%) (strength of evidence was low for short term, moderate for intermediate term).
This seems to confirm what I have been saying for a long time: the benefit of spinal manipulation for chronic back pain is close to zero. This means that the hallmark therapy of chiropractors for the one condition they treat more often than any other is next to useless.
But which other treatments should patients suffering from this frequent and often agonising problem employ? Perhaps the most interesting point of the AHRQ review is that none of the assessed nonpharmacological treatments are supported by much better evidence for efficacy than spinal manipulation. The only two therapies that seem to be even worse are traction and ultrasound (both are often used by chiropractors). It follows, I think, that for chronic low back pain, we simply do not have a truly effective nonpharmacological therapy and consulting a chiropractor for it does make little sense.
What else can we conclude from these depressing data? I believe, the most rational, ethical and progressive conclusion is to go for those treatments that are associated with the least risks and the lowest costs. This would make exercise the prime contender. But it would definitely exclude spinal manipulation, I am afraid.
And this beautifully concurs with the advice I recently derived from the recent Lancet papers: walk (slowly and cautiously) to the office of your preferred therapist, have a little rest there (say hello to the staff perhaps) and then walk straight back home.
In 1995, Dabbs and Lauretti reviewed the risks of cervical manipulation and compared them to those of non-steroidal, anti-inflammatory drugs (NSAIDs). They concluded that the best evidence indicates that cervical manipulation for neck pain is much safer than the use of NSAIDs, by as much as a factor of several hundred times. This article must be amongst the most-quoted paper by chiropractors, and its conclusion has become somewhat of a chiropractic mantra which is being repeated ad nauseam. For instance, the American Chiropractic Association states that the risks associated with some of the most common treatments for musculoskeletal pain—over-the-counter or prescription nonsteroidal anti-inflammatory drugs (NSAIDS) and prescription painkillers—are significantly greater than those of chiropractic manipulation.
As far as I can see, no further comparative safety-analyses between cervical manipulation and NSAIDs have become available since this 1995 article. It would therefore be time, I think, to conduct new comparative safety and risk/benefit analyses aimed at updating our knowledge in this important area.
Meanwhile, I will attempt a quick assessment of the much-quoted paper by Dabbs and Lauretti with a view of checking how reliable its conclusions truly are.
The most obvious criticism of this article has already been mentioned: it is now 23 years old, and today we know much more about the risks and benefits of these two therapeutic approaches. This point alone should make responsible healthcare professionals think twice before promoting its conclusions.
Equally important is the fact that we still have no surveillance system to monitor the adverse events of spinal manipulation. Consequently, our data on this issue are woefully incomplete, and we have to rely mostly on case reports. Yet, most adverse events remain unpublished and under-reporting is therefore huge. We have shown that, in our UK survey, it amounted to exactly 100%.
To make matters worse, case reports were excluded from the analysis of Dabbs and Lauretti. In fact, they included only articles providing numerical estimates of risk (even reports that reported no adverse effects at all), the opinion of exerts, and a 1993 statistic from a malpractice insurer. None of these sources would lead to reliable incidence figures; they are thus no adequate basis for a comparative analysis.
In contrast, NSAIDs have long been subject to proper post-marketing surveillance systems generating realistic incidence figures of adverse effects which Dabbs and Lauretti were able to use. It is, however, important to note that the figures they did employ were not from patients using NSAIDs for neck pain. Instead they were from patients using NSAIDs for arthritis. Equally important is the fact that they refer to long-term use of NSAIDs, while cervical manipulation is rarely applied long-term. Therefore, the comparison of risks of these two approaches seems not valid.
Moreover, when comparing the risks between cervical manipulation and NSAIDs, Dabbs and Lauretti seemed to have used incidence per manipulation, while for NSAIDs the incidence figures were bases on events per patient using these drugs (the paper is not well-constructed and does not have a methods section; thus, it is often unclear what exactly the authors did investigate and how). Similarly, it remains unclear whether the NSAID-risk refers only to patients who had used the prescribed dose, or whether over-dosing (a phenomenon that surely is not uncommon with patients suffering from chronic arthritis pain) was included in the incidence figures.
It is worth mentioning that the article by Dabbs and Lauretti refers to neck pain only. Many chiropractors have in the past broadened its conclusions to mean that spinal manipulations or chiropractic care are safer than drugs. This is clearly not permissible without sound data to support such claims. As far as I can see, such data do not exist (if anyone knows of such evidence, I would be most thankful to let me see it).
To obtain a fair picture of the risks in a real life situation, one should perhaps also mention that chiropractors often fail to warn patients of the possibility of adverse effects. With NSAIDs, by contrast, patients have, at the very minimum, the drug information leaflets that do warn them of potential harm in full detail.
Finally, one could argue that the effectiveness and costs of the two therapies need careful consideration. The costs for most NSAIDs per day are certainly much lower than those for repeated sessions of manipulations. As to the effectiveness of the treatments, it is clear that NSAIDs do effectively alleviate pain, while the evidence seems far from being conclusively positive in the case of cervical manipulation.
In conclusion, the much-cited paper by Dabbs and Lauretti is out-dated, poor quality, and heavily biased. It provides no sound basis for an evidence-based judgement on the relative risks of cervical manipulation and NSAIDs. The notion that cervical manipulations are safer than NSAIDs is therefore not based on reliable data. Thus, it is misleading and irresponsible to repeat this claim.
