I have published many articles on the risks of various alternative treatments (see for instance here, here, here, here, here and here) – not because I am alarmist but because I have always felt very strongly that, for a researcher into alternative medicine, the most important issue must be to make sure users of these therapies are as safe as possible. Usually I differentiated between direct and indirect risks. The former relate to the risks of the treatment and include, for instance, liver damage caused by a herbal remedy or stroke due to neck manipulation. The latter are mainly due to the poor, often irresponsible advice given by many therapists.

A recent article adopted the same terminology when reviewing the risks of alternative medicine specifically for cancer patients. As the indirect risks are often neglected, I will here quote the relevant section of this paper in full:

…Health care physicians and oncology experts have an ethical responsibility to initiate the communication regarding the use of complementary therapies with cancer patients. However, according to data obtained from this literature review, oncology doctors and physicians will discuss complementary therapies only when a patient him/herself raises this issue within a consultation. This passive attitude was linked to a lack of sufficient scientific evidence for positive outcomes of complementary therapies found in high quality randomized controlled trials (RCTs). Oncology nurses, on the other hand, sometimes actively promote complementary modalities that they find to correspond with their vision of holistic care.

According to the included studies, complementary providers often differ from conventional health care providers in their understanding of treatment concepts, philosophies and diagnostic procedures. This leads to different models of disease causality (cells, blood, nerves vs. energy, vital force, meridians) and treatment philosophy (reductionism vs. holism). As many complementary providers are philosophically oriented towards personal and spiritual growth, patients may feel guilty if the disease continues to advance despite the patients’ best spiritual and mental efforts. According to Broom and colleagues, such philosophies may also give patients false hope of recovery.

Another indirect risk connected to the combination of conventional and complementary treatment in cancer care is the lack of regulation and standardized education in many countries. Currently, there are, for example, no standard training requirements for complementary providers working in cancer care or any other health care setting in the EU. According to Mackareth et al., complementary providers in England need specific training to learn how to practice safely.

Moreover, there is a need for common medical terminology to bridge the communication gap between health care providers working outside the conventional health care system. Common medical terminology may reduce the existing communication gap between conventional and complementary providers about mutual patients. To minimize communication gap between physicians, oncology experts and complementary providers, a medical complementary record should include a treatment plan with conventional and complementary diagnosis, explanation of terminology, possible treatment interactions, description of the complementary treatment plan and goals. If possible, the quality of any complementary supplement given should be reported.

END OF QUOTE

As I said, I find it important to discuss the indirect risks of alternative medicine, and I am therefore pleased that the authors of this article addressed them. At the same time, I find their text remarkably tame.

Why are they not more open and forceful about what, after all, amounts to a serious public health issue? The answer might be simpler than expected: most of them are affiliated with the ‘National Research Center in Complementary and Alternative Medicine (NAFKAM), UiT The Arctic University of Norway, Tromsø, Norway’. Could it be that open warnings about outright quackery is not what suits this unit?

So, what might be an open and frank approach to discussing the indirect risks of alternative medicine? In my view, it should make several points abundantly clear and transparent:

  • Alternative practitioners (APs) are usually not trained to advise patients responsibly, particularly in cases serious disease.
  • The training of APs is often inadequate and sometimes resembles more to brain-washing than to proper education.
  • Consequently, APs often woefully over-estimate what their therapy can achieve.
  • The patients of APs are often desperate and ready to believe even the tallest tales.
  • APs have a huge conflict of interest – in order to make a living they need to treat as many patients as possible and are therefore not motivated to refer them to more suitable care.
  • APs are frequently in denial when it comes to the risks of their treatments.
  • APs are not educated such that they understand the full complexities of serious illness.
  • As a result, APs far too often misguide their patients to make tragically wrong choices thus putting their health at serious risk.
  • In most countries, the regulators turn a blind eye to this huge problem.

These are by no means trivial  points, and they have nothing to do with a ‘turf war’ between conventional and alternative medicine. They relate to our ethical duty to keep our patients as safe as we can. It has been estimated that, in oncology alone, 1 – 5% of deaths are due to patients opting to have alternative instead of conventional treatments. This amounts to an unbearably high absolute number of patients dying prematurely due to the indirect risks of alternative medicine.

It is high time, I think, that we tackle this issue systematically and seriously.

Stable angina is a symptom of coronary heart disease which, in turn, is amongst the most frequent causes of death in developed countries. It is an alarm bell to any responsible clinician and requires causal, often life-saving treatments of which we today have several options. The last thing a patient needs in this condition is ACUPUNCTURE, I would say.

Yet acupuncture is precisely the therapy such patients might be tempted to employ.

Why?

Because irresponsible or criminally naïve acupuncturists advertise it!

Take this website, for instance; it informs us that a meta-analysis of eight clinical trials conducted between 2000 and 2014 demonstrates the efficacy of acupuncture for the treatment of stable angina. In all eight clinical trials, patients treated with acupuncture experienced a greater rate of angina relief than those in the control group treated with conventional drug therapies (90.1% vs 75.7%)….

I imagine that this sounds very convincing to patients and I fear that many might opt for acupuncture instead of potentially invasive/unpleasant but life-saving intervention. The original meta-analysis to which the above promotion referred to is equally optimistic. Here is its abstract:

Angina pectoris is a common symptom imperiling patients’ life quality. The aim of this study is to evaluate the efficacy and safety of acupuncture for stable angina pectoris. Clinical randomized-controlled trials (RCTs) comparing the efficacy of acupuncture to conventional drugs in patients with stable angina pectoris were searched using the following database of PubMed, Medline, Wanfang and CNKI. Overall odds ratio (ORs) and weighted mean difference (MD) with their 95% confidence intervals (CI) were calculated by using fixed- or random-effect models depending on the heterogeneity of the included trials. Total 8 RCTs, including 640 angina pectoris cases with 372 patients received acupuncture therapy and 268 patients received conventional drugs, were included. Overall, our result showed that acupuncture significantly increased the clinical curative effects in the relief of angina symptoms (OR=2.89, 95% CI=1.87-4.47, P<0.00001) and improved the electrocardiography (OR=1.83, 95% CI=1.23-2.71, P=0.003), indicating that acupuncture therapy was superior to conventional drugs. Although there was no significant difference in overall effective rate relating reduction of nitroglycerin between two groups (OR=2.13, 95% CI=0.90-5.07, P=0.09), a significant reduction on nitroglycerin consumption in acupuncture group was found (MD=-0.44, 95% CI=-0.64, -0.24, P<0.0001). Furthermore, the time to onset of angina relief was longer for acupuncture therapy than for traditional medicines (MD=2.44, 95% CI=1.64-3.24, P<0.00001, min). No adverse effects associated with acupuncture therapy were found. Acupuncture may be an effective therapy for stable angina pectoris. More clinical trials are needed to systematically assess the role of acupuncture in angina pectoris.

In the discussion section of the full paper, the authors explain that their analysis has several weaknesses:

Several limitations were presented in this meta-analysis. Firstly, conventional drugs in control group were different, this may bring some deviation. Secondly, for outcome of the time to onset of angina relief with acupuncture, only one trial included. Thirdly, the result of some outcomes presented in different expression method such as nitroglycerin consumption. Fourthly, acupuncture combined with traditional medicines or other factors may play a role in angina pectoris.

However, this does not deter them to conclude on a positive note:

In conclusion, we found that acupuncture therapy was superior to the conventional drugs in increasing the clinical curative effects of angina relief, improving the electrocardiography, and reducing the nitroglycerin consumption, indicating that acupuncture therapy may be effective and safe for treating stable angina pectoris. However, further clinical trials are needed to systematically and comprehensively evaluate acupuncture therapy in angina pectoris.

So, why do I find this irresponsibly and dangerously misleading?

Here a just a few reasons why this meta-analysis should not be trusted:

  • There was no systematic attempt to evaluate the methodological rigor of the primary studies; any meta-analysis MUST include such an assessment, or else it is not worth the paper it was printed on.
  • The primary studies all look extremely weak; this means they are likely to be false-positive.
  • They often assessed not acupuncture alone but in combination with other treatments; consequently the findings cannot be attributed to acupuncture.
  • All the primary studies originate from China; we have seen previously (see here and here) that Chinese acupuncture trials deliver nothing but positive results which means that their results cannot be trusted: they are false-positive.

My conclusion: the authors, editors and reviewers responsible for this article should be ashamed; they committed or allowed scientific misconduct, mislead the public and endangered patients’ lives.

We have become used to bogus claims made by homeopaths – far too much so, I would argue. Therefore, we let the vast majority of their bogus claims pass without serious objections. Yet exposing bogus claims would be an important task, particularly when they relate to serious conditions. Doing this might even save lives!

According to the website of the ‘HOMEOPATHIC DOCTOR’, homeopathy is mild in nature and tends to modify the body’s natural immunity. It is the responsibility of the immune system of the body to protect it from all sorts of damage, whether from bacteria or viruses or from any other disease. It also helps in repairing any damage that may occur at any time. Homeopathic medicines help strengthen the natural immunity of the body so that it can perform its natural functions in a more efficient manner.

5 Best Homeopathic remedies for Ulcerative Colitis

In my experience, homeopathic medicines like Merc Sol, Baptisia, Nux Vomica, Arsenic Album and Phosphorus have been found to be quite effective in the treatment of Ulcerative Colitis…

Merc Sol- One of the best homeopathic medicines for ulcerative colitis with blood and tenesmus

When there is too much bleeding with tenesmus and other symptoms, Merc Sol is one of the best homeopathic medicines for ulcerative colitis. There are frequent stools with blood being discharged almost every time. The patient is a sweaty sort of patient who keeps on sweating most of the time. Creeping sort of chilliness may be felt in the back.

Nux Vomica- One of the best homeopathic remedies for ulcerative colitis due to high life

When the problem has occurred from living a high life, Nux Vomica is one of the best homeopathic remedies for ulcerative colitis. Excess of alcohol, stimulants like tea and coffee, late night partying and other habits incident to modern lifestyle can contribute to such a problem. The patient is usually a chilly sort of patient who cannot tolerate cold. He is unusually angry and that too at trifles.

Arsenic Album – One of the best homeopathic medicines for ulcerative colitis with anxiety and restlesness

When the predominant symptoms are the mental symptoms of anxiety and restlessness, Arsenic Album is one of the best homeopathic medicines for ulcerative colitis. The patient gets anxious, worried and restless for no rhyme or reason. There may be weakness which may be disproportionately more than the problem. There is increased thirst for water, though the patient takes a small quantity or a sip at a time.

Baptisia – One of the best homeopathic remedy for ulcerative colitis with low grade fever

When there is low grade fever present along with other symptoms, Baptisia is one of the best homeopathic remedy for ulcerative colitis. The patient has great muscular soreness all over the body as if bruised and beaten. Appetite is reduced or next to nil. At the same time, there is constant desire for water. Stools are very offensive, thin and watery.

Phosphorus – One of the best homeopathic medicine for ulcerative colitis with increased thirst for cold water

When there is intense thirst for cold water, Phosphorus is one of the best homeopathic medicine for ulcerative colitis. The patient is usually tall and thin. The diarrhoea is copious. Stool is watery and profuse bleeding may be present. Patient feels too weak and more so after passing a stool.

The ‘HOMEOPATHIC DOCTOR’s first statement was ‘in my experience…’? Unfortunately most patients will not understand what this expression truly means when written by a homeopath. It means THERE IS NOT A JOT OF EVIDENCE FOR ANY OF THIS. Had he stated this clearly, it would probably have been the only correct sentence in the whole article.

People who understand medicine a bit might laugh at such deluded clinicians and their weird, unethical recommendations. However, patients who are chronically ill and therefore desperate might take them seriously and follow their advice. Patients who suffer from potentially life-threatening diseases like ulcerative colitis might then cause serious damage to themselves or even die.

And this is precisely the reason why I will continue to expose these charlatans for what they are: irresponsible, unethical, uninformed, dangerous quacks

For far too many proponents of alternative medicine, belief in alternative methods seems disappointingly half-hearted. Not so for this enthusiast who invented an alternative form of resuscitation – but sadly failed.

This article explains:

A Russian woman spent more than 4 months trying to bring her dead husband back to life. How?  With the help of holy water and prayer!

The retired therapist said she didn’t report the death of her 87-year-old husband because she believed she could revive him by sprinkling holy water on his body and reading prayers. The woman’s bizarre secret was revealed when she accidentally flooded the apartment below, and a neighbour forced his way into her home to turn off the water. He found the almost completely mummified husband laying on the living-room couch. Forensic pathologists determined that the man had been dead for 4 – 6 months, but found no traces of violence on his body and concluded he had died of natural causes.

Neighbours said that they did sense a strange smell coming out of the apartment, but didn’t think anything of it. The deceased had suffered a serious injury to his leg in 2015 and had been bed-ridden since then. Therefore his disappearance from public view went unnoticed. To make sure nobody interfered with her resuscitations, the woman told everyone that he was fine, but too tired for receiving guests. Even the couple’s children were asked not to visit.

The 76-year-old woman who had worked as a doctor for most of her life, became interested in the occult and obsessed with the work of Leonid Konovalov, a Russian psychic who stars in a television show where he tries to communicate with the dead. “When we started talking to the woman, it turned out that she was fascinated by alternative medicine and believed that, by sprinkling holy water on her husband, she would be able to bring him back, to revive him,” Chief investigator commented.

Is there a lesson in this story?

Perhaps this one: conviction in one’s methods might be good, but evidence is better.

This sad story was reported across the world. It is tragic and, at the same time, it makes me VERY angry. A women lost her life after giving birth due to the incompetence of her midwife. On this website, we learn the following gruesome details:

Many question the culpability of Australian midwife Gaye Demanuele in the wake of the investigations into the death of Caroline Lovell during her home birth in 2012. And while Demanuele played a major role in Lovell’s passing, a closer look may show the real culprit: homeopathy. In January 2012, Demanuele, an outspoken home birth advocate, served as senior midwife in Lovell’s home birth. After giving birth, Lovell experienced severe blood loss and begged to call an ambulance. According to the investigating coroner, Demanuele refused several times, never checking her patient’s blood pressure or effectively monitoring her blood loss. Demanuele instead tried a homeopathic “remedy” to relieve Lovell’s anxiety. Only after Lovell fainted in a pool of her own blood and went into cardiac arrest was she taken to a hospital, where she died 12 hours later…

We know that many midwifes are besotted with alternative medicine. Their love-affair with quackery had to lead to serious harm sooner or later. This story is thus tragic and awful – but it is not surprising.

What makes me angry, is the complete lack of critical comment from homeopaths and their professional organisations. Where are the homeopaths who state clearly and categorically that the use of homeopathic remedies in the situation described above (and indeed in midwifery generally) is not based on sound evidence? In fact, it is criminal charlatanry!

Homeopaths are usually not lost for words.

Where is the homeopathic organisation stating that a bleeding patient does not need homeopathy?

How should we interpret this deafening silence?

Does it mean that those homeopaths who quietly tolerate charlatanry are themselves charlatans?

If so, would this not be 100% of them?

If you ever receive an email from ‘edzardernst@yahoo.com’, please be aware that it is not from me. It comes from some clown who seems to want to pretend to be me.

How do I know? I received a short email from that very person. Here is its full text in all its beauty:

You are the most bullshit person i know who claim to be a good doctor by putting other professions down. you are a killer because of your false information.”

What does that tell us about the identity of the author?

  1. He does not seem to be an admirer of my work.
  2. He feels strongly about something.
  3. He does not mince his words.
  4. He does not write very good English.
  5. He is not very well-informed [I do not think that I ever claimed to be a ‘good doctor’].
  6. He is factually wrong [I have not ever killed anyone for any reason].

What he presumably wants to express is that, in his view, the information I publish on this blog and perhaps elsewhere has the potential to kill patients. This is a somewhat disturbing assumption because the opposite is truly my intention.

It is a great pity that the author of these lines did not manage to be a little more specific.

  1. Does he [somehow, I presume the author is male] think that, by warning readers of all sorts of quackery and outright health fraud, I might kill someone?
  2. Does he believe that my repeated warnings about the lack of good evidence for alternative medicine drive patients into the arms of even more dangerous clinicians?
  3. Or is he just an unfortunate sufferer of a serious mental condition such as paranoia?

As I am totally in the dark here and cannot even begin to answer these questions, I will leave it to you, the readers of this post, to decide.

Or perhaps the author of this charming email wants to enlighten us?

Many people seem to believe that homeopathy is harmless. It is a belief that can easily be shown to be wrong, and this blog has repeatedly done just that. Perhaps the best researched issue here is the stance of many homeopaths against vaccination.  But this is by no means all.

There are uncounted books, articles and websites which mislead consumers into believing that they can cure their illnesses with homeopathy. Take the website of ‘STAR HOMEOPATHY’ for instance. This organisation makes fantastic promises:

Star homeopathy, a chain of super specialty homeopathic clinic’s founded by a group of practically high qualified doctors with the vision to provide the best medical treatment in a scientific and most advanced way with the use of latest clinical knowledge and medical diagnostic equipment.

We at star homeopathy, confidently say that we accurately diagnose the disease condition and treat all chronic diseases very efficiently without harming the patient’s body.

Such statements are bound to inspire confidence to many people who are chronically ill and frustrated with the fact that they need to take drugs for the rest of their lives to stay alive. Patients suffering from diabetes, for instance. They might hope that STAR HOMEOPATHY has a solution for them. And true enough, they do:

How Homoeopathy helps to cure Diabetes?

In homeopathy, diabetes is seen as a reflection of the body’s inability to function optimally. There is an imbalance that results in the body’s incapacity to effectively utilize the insulin that it produces, or to produce sufficient insulin for its needs. While symptoms often disappear after conventional treatment, the vital force does not. Homoeopathy can be used effectively in the treatment of diabetes. Here we mainly concentrate on functioning of the pancreas in efficient insulin production. The metabolic condition of a patient suffering from diabetes requires both therapeutic and nutritional measures to correct the illness. Homeopathy can regulate sugar metabolism while helping to resolve the metabolic disturbances that lead to diabetes. Furthermore, homeopathy helps stimulate the body’s self-healing powers in order to prevent complications such as open leg sores and other dysfunctions of the blood vessel, loss of vision, kidney failure. Homeopathic treatment does not target one illness, an organ, a body part or a symptom. Remedies are prescribed based on an assembly of presenting symptoms, their stresses in life.

Commonly indicated Homoeopathic remedies:

Syzygium: A most useful remedy in diabetes mellitus. No other remedy causes in so marked degree the diminution and disappearance of sugar in the urine. Prickly heat in upper part of the body; small red pimples itch violently. Great thirst, weakness, emaciation. Very large amounts of urine.. Diabetic ulceration.. Syzygium Jambolanum has marked action on diabetes mellitus as it causes marked diminution of sugar in urine. Great thirst with weakness, emaciation inspite of proper nutritious diet. Profuse urination of high specific gravity. Small red pimples with much itching. Syzygium Jambolanum also helps in treating old ulcers of skin associated with diabetes mellitus.

Uranium nitricum: Uranium Nitricum is a chief diuretic remedy. There is copious urination with incontinence of urine. It is indicated in glycosuria with increased urination, emaciation and tympanites. Uranium Nitiricum also helps in enuresis, the patient is unable to retain urine without pain. Burning in urethra, with very acid urine. There is a tendency to great emaciation, debility and general dropsy. Causes glycosuria and increased urine. Is known to produce nephritis, diabetes, degeneration of the liver, high blood pressure and dropsy. Its therapeutic keynote is Great emaciation, debility and tendency to ascites and general dropsy. Backache and delayed menses. Dry mucous membranes and skin.

Lycopodium: Diabetes. Anger during disease. Lost of self confidence. The right side conditions works well and thus improve the liver and kidney functioning as conditions Neuropathy. There is constipation due to inactivity of the rectum. Impotence. Intense desire for sweets.

So, if you think that homeopathy is harmless, think again!

Following this advice, could mean the death of many diabetics.

No treatment for which hugely exaggerated claims abound can ever be safe.

If we listen to acupuncturists and their supporters, we might get the impression that acupuncture is totally devoid of risk. Readers of this blog will know that this is not quite true. A recent case report is a further reminder that acupuncture can cause serious complications; in extreme cases it can even kill.

A male patient in his late forties died right after an acupuncture treatment. A medico-legal autopsy disclosed severe haemorrhaging around the right vagus nerve in the neck. All other organs were normal, and laboratory findings revealed nothing significant. Thus, the authors of this case-report concluded that the man most probably died from severe vagal bradycardia and/or arrhythmia resulting from vagus nerve stimulation following acupuncture: To the best of our knowledge, this is the first report of a death due to vagus nerve injury after acupuncture.

In total, around 100 deaths have been reported after acupuncture in the medical literature. ‘This is a negligible small figure’ claim acupuncture fans. True, it is a small number, but it could just be the tip of a much larger ice-berg: there is no reporting system that could possibly pick up severe complications, and in the absence of such a scheme, nobody can name reliable incidence rates. And even if the numbers of severe complications and deaths are small – even a single fatality would seem one too many.

The deaths that are currently on record are mostly due to bilateral pneumothorax or cardiac tamponade. The present case of vagus nerve injury seems to be ‘a first’. Perhaps we should watch out for similar events?

IF WE DON’T LOOK, WE DON’T SEE.

Few subjects make chiropractors more uneasy than a discussion of the safety of their spinal manipulations. Many chiropractors flatly deny that there are any risks at all. However, the evidence seems to tell a different story.

The purpose of a new review was to summarise the literature for cases of adverse events in infants and children treated by chiropractors or other manual therapists, identifying treatment type and if a preexisting pathology was present. English language, peer-reviewed journals and non-peer-reviewed case reports discussing adverse events (ranging from minor to serious) were systematically searched from inception of the relevant searchable bibliographic databases through March 2014. Articles not referring to infants or children were excluded.

Thirty-one articles met the selection criteria. A total of 12 articles reporting 15 serious adverse events were found. Three deaths occurred under the care of various providers (1 physical therapist, 1 unknown practitioner, and 1 craniosacral therapist) and 12 serious injuries were reported (7 chiropractors/doctors of chiropractic, 1 medical practitioner, 1 osteopath, 2 physical therapists, and 1 unknown practitioner). High-velocity, extension, and rotational spinal manipulation was reported in most cases, with 1 case involving forcibly applied craniosacral dural tension and another involving use of an adjusting instrument. Underlying preexisting pathology was identified in a majority of the cases.

The authors concluded that published cases of serious adverse events in infants and children receiving chiropractic, osteopathic, physiotherapy, or manual medical therapy are rare. The 3 deaths that have been reported were associated with various manual therapists; however, no deaths associated with chiropractic care were found in the literature to date. Because underlying preexisting pathology was associated in a majority of reported cases, performing a thorough history and examination to exclude anatomical or neurologic anomalies before applying any manual therapy may further reduce adverse events across all manual therapy professions.

This review is a valuable addition to our knowledge about the risks of spinal manipulations. My own review summarised 26 deaths after chiropractic manipulations. In several of these instances, the age of the patient had not been reported. Therefore the above conclusion (no deaths associated with chiropractic) seems a little odd.

The following text is a shortened version of the discussion of my review which, I think, addresses most of the pertinent issues.

 numerous deaths have been associated with chiropractic. Usually high-velocity, short-lever thrusts of the upper spine with rotation are implicated. They are believed to cause vertebral arterial dissection in predisposed individuals which, in turn, can lead to a chain of events including stroke and death. Many chiropractors claim that, because arterial dissection can also occur spontaneously, causality between the chiropractic intervention and arterial dissection is not proven. However, when carefully evaluating the known facts, one does arrive at the conclusion that causality is at least likely. Even if it were merely a remote possibility, the precautionary principle in healthcare would mean that neck manipulations should be considered unsafe until proven otherwise. Moreover, there is no good evidence for assuming that neck manipulation is an effective therapy for any medical condition. Thus, the risk-benefit balance for chiropractic neck manipulation fails to be positive.

Reliable estimates of the frequency of vascular accidents are prevented by the fact that underreporting is known to be substantial. In a survey of UK neurologists, for instance, under-reporting of serious complications was 100%. Those cases which are published often turn out to be incomplete. Of 40 case reports of serious adverse effects associated with spinal manipulation, nine failed to provide any information about the clinical outcome. Incomplete reporting of outcomes might therefore further increase the true number of fatalities.

This review is focussed on deaths after chiropractic, yet neck manipulations are, of course, used by other healthcare professionals as well. The reason for this focus is simple: chiropractors are more frequently associated with serious manipulation-related adverse effects than osteopaths, physiotherapists, doctors or other professionals. Of the 40 cases of serious adverse effects mentioned above, 28 can be traced back to a chiropractor and none to a osteopath. A review of complications after spinal manipulations by any type of healthcare professional included three deaths related to osteopaths, nine to medical practitioners, none to a physiotherapist, one to a naturopath and 17 to chiropractors. This article also summarised a total of 265 vascular accidents of which 142 were linked to chiropractors. Another review of complications after neck manipulations published by 1997 included 177 vascular accidents, 32 of which were fatal. The vast majority of these cases were associated with chiropractic and none with physiotherapy. The most obvious explanation for the dominance of chiropractic is that chiropractors routinely employ high-velocity, short-lever thrusts on the upper spine with a rotational element, while the other healthcare professionals use them much more sparingly.

[REFERENCES FOR THE ABOVE STATEMENTS CAN BE FOUND IN MY REVIEW]

Adverse events have been reported extensively following chiropractic.  About 50% of patients suffer side-effects after seeing a chiropractor. The majority of these events are mild, transitory and self-limiting. However, chiropractic spinal manipulations, particularly those of the upper spine, have also been associated with very serious complications; several hundred such cases have been reported in the medical literature and, as there is no monitoring system to record these instances, this figure is almost certainly just the tip of a much larger iceberg.

Despite these facts, little is known about patient filed compensation claims related to the chiropractic consultation process. The aim of a new study was to describe claims reported to the Danish Patient Compensation Association and the Norwegian System of Compensation to Patients related to chiropractic from 2004 to 2012.

All finalized compensation claims involving chiropractors reported to one of the two associations between 2004 and 2012 were assessed for age, gender, type of complaint, decisions and appeals. Descriptive statistics were used to describe the study population.

338 claims were registered in Denmark and Norway between 2004 and 2012 of which 300 were included in the analysis. 41 (13.7%) were approved for financial compensation. The most frequent complaints were worsening of symptoms following treatment (n = 91, 30.3%), alleged disk herniations (n = 57, 19%) and cases with delayed referral (n = 46, 15.3%). A total financial payment of €2,305,757 (median payment €7,730) were distributed among the forty-one cases with complaints relating to a few cases of cervical artery dissection (n = 11, 5.7%) accounting for 88.7% of the total amount.

The authors concluded that chiropractors in Denmark and Norway received approximately one compensation claim per 100.000 consultations. The approval rate was low across the majority of complaint categories and lower than the approval rates for general practitioners and physiotherapists. Many claims can probably be prevented if chiropractors would prioritize informing patients about the normal course of their complaint and normal benign reactions to treatment.

Despite its somewhat odd conclusion (it is not truly based on the data), this is a unique article; I am not aware that other studies of chiropractic compensation  claims exist in an European context. The authors should be applauded for their work. Clearly we need more of the same from other countries and from all professions doing manipulative therapies.

In the discussion section of their article, the authors point out that Norwegian  and Danish chiropractors both deliver approximately two million consultations annually. They receive on average 42 claims combined suggesting roughly one claim per 100.000 consultations. By comparison, Danish statistics show that in the period 2007–2012 chiropractors, GPs and physiotherapists (+ occupational therapists) received 1.76, 1.32 and 0.52 claims per 100.000 consultations, respectively with approval rates of 13%, 25% and 21%, respectively. During this period these three groups were reimbursed on average €58,000, €29,000 and €18,000 per approved claim, respectively.

These data are preliminary and their interpretation might be a matter of debate. However, one thing seems clear enough: contrary to what we frequently hear from apologists, chiropractors do receive a considerable amount of compensation claims which means many patients do get harmed.
