Hurray, I can hear the Champagne corks popping: this month is ‘National Chiropractic Months’ in the USA – a whole month! This has depleted my stock of the delicious fizz already in the first three days.
Now that my bottles are empty (is there a chiropractic cure for a hang-over?), I must find other ways to celebrate. How about a more sober look at what has been published in the medical literature on chiropractic during the last few days?
A quick look into Medline identifies several articles of interest. The very first one is a case-report:
Spinal epidural hematoma (SEH) occurring after chiropractic spinal manipulation therapy (CSMT) is a rare clinical phenomenon. Our case is unique because the patient had an undiagnosed cervical spinal arteriovenous malformation (AVM) discovered on pathological analysis of the evacuated hematoma. Although the spinal manipulation likely contributed to the rupture of the AVM, there was no radiographic evidence of the use of excessive force, which was seen in another reported case. As such, patients with a known AVM who have not undergone surgical intervention should be cautioned against symptomatic treatment with CSMT, even if performed properly. Regardless of etiology, SEH is a surgical emergency and its favorable neurological recovery correlates inversely with time to surgical evacuation.
This is important, I think, in more than one way. Many chiropractors simply deny that their manipulations cause serious complications of this nature. Yet such cases are being reported with depressing regularity. Other chiropractors claim that excessive force is necessary to cause the damage. This paper seems to refute this notion quite well, I think.
But let’s not be inelegant and dwell on this unpleasant subject; it might upset chiros during their month of celebration.
The next article fresh from the press is a survey – chiropractors are very fond of this research tool, it seems. It produced a lot of intensely boring data – except for one item that caught my eye: the authors found that ‘virtually all Danish chiropractors working in the primary sector made use of manipulation as one of their treatment modalities.’
Why is that interesting? Whenever I point out that there is no good evidence that chiropractic manipulations generate more good than harm, chiropractors tend to point out that they do so much more than that. Manipulations are not administered to all their patients, they say. This survey is a reminder (there is plenty more evidence on this issue) of the fact that the argument is not very convincing.
Another survey which has just been published in time for the ‘celebratory month’ is worth mentioning. It reports the responses of patients to questions about chiropractic by providing the ‘positive angle’, e.g.: ‘Most (61.4%) respondents believed that chiropractic care was effective at treating neck and back pain…’ Just for the fun of it, I thought it might be worth doing the opposite: 39% did not believe that chiropractic care was effective at treating neck and back pain… If we use this approach, the new survey also indicates that about half of the respondents did not think chiropractors were trustworthy, and 86% have not consulted a chiropractor within the last year.
Oh, so sorry – I did not mean to spoil the celebrations! Better move on then!
A third survey assessed the attitudes of Canadian obstetricians towards chiropractic. Overall, 70% of respondents did not hold a positive views toward chiropractic, 74% did not agree that chiropractic had a role in treatment of non-musculoskeletal conditions, 60% did not refer at least some patients for chiropractic care each year, and comments of the obstetricians revealed concerns regarding safety of spinal manipulation and variability among chiropractors.
And now I better let you get on with your well-deserved celebrations and look for another bottle!
The question why patients turn to homeopathy – or indeed any other disproven treatment – has puzzled many people. There has been a flurry of research into these issues. Here is the abstract of a paper that I find very remarkable and truly fascinating:
Interviews with 100 homeopathic patients in the San Francisco Bay Area show that for the most part the patients are young, white and well-educated, and have white-collar jobs; most had previously tried mainstream medical care and found it unsatisfactory. Among the reasons for their dissatisfaction were instances of negative side effects from medication, lack of nutritional or preventive medical counseling, and lack of health education. Experiences with conventional physicians were almost evenly divided: nearly half of the subjects reported poor experiences, slightly fewer reported good experiences. Three quarters of the patients suffered from chronic illness and about half considered their progress to be good under homeopathic care. The majority were simultaneously involved in other nontraditional health care activities.
If you read the full article, you will see that the authors make further important points:
- Patients who use alternative treatments are by no means ignorant or unsophisticated.
- Most of these patients use other treatments in parallel – but they seem to attribute any improvements in their condition to homeopathy.
- Dissatisfaction with conventional medicine seems the prime motivation to turn to homeopathy. In particular, patients need more time with their clinician and want to share the responsibility for their own health – and these needs are met by homeopaths better than by conventional doctors.
- Most homeopaths (63%) adhere to Hahnemann’s dictum that homeopathic remedies must never be combined with other treatments. This renders then potentially dangerous in many situations.
At this point you might say BUT WE KNEW ALL THIS BEFORE! True! Why then do I find this paper so remarkable?
It is remarkable mostly because of its publication date: 1978! In fact, it may well be the very first of hundreds of similar surveys that followed in the years since.
The questions I ask myself are these:
- IF WE KNEW ALL THIS SINCE ALMOST 40 YEARS, WHY HAVE WE NOT DONE MORE ABOUT IT?
- WHY ARE WE SO UNSUCCESSFUL IN GETTING THE FACTS THROUGH TO OUR PATIENTS?
- WHY HAVE WE NOT MANAGED TO IMPROVE CONVENTIONAL MEDICINE SUCH THAT PATIENTS STOP CONSULTING QUACKS?
- WHY ARE WE STILL CONDUCTING SURVEY AFTER SURVEY WHEN THE EMBARRASSING FACTS ARE PLAIN TO SEE?
Homeopathy is very popular in India – at least this is what we are being told over and over again. The notion goes as far as some sources assuming that homeopathy is quintessential Indian (see below). One Website, informs us that homeopathy is the third most popular method of treatment in India, after Allopathy and Ayurveda. It is estimated that there are about quarter million homeopaths in India. Nearly 10,000 new ones add to this number every year. The legal status of homeopathy in India is very much at par with the conventional medicine.
Another website currently advises the Indian population as well as heath tourists from abroad about homeopathy in the following terms:
Homeopathic medicines have various benefits. Some of them are as follows:
- Such medicines can be given to infants, children, pregnant or nursing woman
- If by chance, wrong medication is prescribed, it is not going to have any ill-effect
- These medicines can be taken along with other medications
- Homeopathic treatment can be used by anyone
- The medicines work on the eradication of the symptoms so that illness never comes back
- These medicines can be stored for a longer span of time and are inexpensive as well
- Homeopathy has a holistic approach and deals with mind, body and emotions
- These medicines are non-invasive and extremely effective
- These medicines can be administered easily
- Homeopathy useful in a number of health problems
Homeopathic Remedies, for Diseases and Conditions
- Acute fevers
- Sore throats
- Mild depression
- Injuries with blunt objects
- Loss of appetite
But is it really true that so many Indian consumers swear by homeopathy, or is that just one of the many myths from the realm of quackery that stubbornly refuse to disappear ?
A survey recently conducted by Indian National Sample Survey Office might provide some answers. It revealed that 90 per cent of the Indian population rely on conventional medicine. Merely 6% trusted what the investigators chose to call ‘Indian systems of medicine’, e. g. ayurveda, unani and siddha, homeopathy and yoga and naturopathy.
Odd? Not really! There are several plausible explanations for this apparent contradiction:
- The popularity of homeopathy in India could be a myth promoted by apologists.
- The figures could be correct, and many Indian patients could use homeopathy not because they believe in it but because they cannot afford effective treatments.
- The claim of homeopathy’s popularity could refer to the past, while the recent survey clearly relates to the present.
Whatever the true answer might be, I think this little news story is an instructive example for the fact that the ‘argumentum ad populum’ is a fallacy that easily can mislead us.
I will state my position up front: THERE IS NO CHILDHOOD CONDITION FOR WHICH CHIROPRACTIC SPINAL MANIPULATION GENERATES MORE GOOD THAN HARM. What is more, I have published evidence (published here, here, here, and here, for instance) to support this statement. If you disagree with it, this is the place and time to do so – and please don’t forget to cite the evidence that supports your statements.
Given that there is very little reliable evidence in this area, I find it surprising that so many chiropractors continue to treat kids. Not true! I hear some chiropractors shout, we do not often treat children. Who is correct? Clearly, we need data to answer this question.
The objective of a new paper was to investigate characteristics of clinical chiropractic practice, including the age of pediatric patients, the number of reports of negative side effects (NSEs), the opinions of doctors of chiropractic on treatment options by patient age groups, the conditions seen and the number of treatment sessions delivered by conditions and by patient age.
An Internet cross-sectional survey was conducted in 20 European countries with 4109 chiropractors invited to reply. The 19 national associations belonging to the European Chiropractic Union and the Danish Chiropractic Association were asked to participate. Respondents were asked to self-report characteristics of their practices.
Of the 956 (23.3%) participating chiropractors, 921 reported 19821 pediatric patients per month. Children represented 8.1% of chiropractors’ total patient load over the last year. A total of 557 (534 mild, 23 moderate, and 0 severe) negative (adverse) side effects were reported for an estimated incidence of 0.23%. On the given treatment statements, chiropractors reported varying agreement and disagreement rates based on patient age. The 8309 answers on conditions were grouped into skeletal (57.0%), neurologic (23.7%), gastrointestinal (12.4%), infection (3.5%), genitourinary (1.5%), immune (1.4%), and miscellaneous conditions (0.5%). The number of treatment sessions delivered varied according to the condition and the patient age.
The authors of this survey concluded that this study showed that European chiropractors are active in the care of pediatric patients. Reported conditions were mainly skeletal and neurologic complaints. In this survey, no severe NSEs were reported, and mild NSEs were infrequent.
In my view, a more appropriate conclusion might be that MANY EUROPEAN CHIROPRACTORS ARE ACTIVE IN QUACKERY.
Recently, I was sent an interesting press release; here it is in full:
A new study has shed light on how cancer patients’ attitudes and beliefs drive the use of complementary and alternative medicine. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may help hospitals develop more effective and accessible integrative oncology services for patients.
Although many cancer patients use complementary and alternative medicine, what drives this usage is unclear. To investigate, a team led by Jun Mao, MD and Joshua Bauml, MD, of the Abramson Cancer Center at the University of Pennsylvania’s Perelman School of Medicine, conducted a survey-based study in their institution’s thoracic, breast, and gastrointestinal medical oncology clinics.
Among 969 participants surveyed between June 2010 and September 2011, patients who were younger, those who were female, and those who had a college education tended to expect greater benefits from complementary and alternative medicine. Nonwhite patients reported more perceived barriers to the use of complementary and alternative medicine compared with white patients, but their expectations concerning the medicine’s benefits were similar. Attitudes and beliefs about complementary and alternative medicine were much more likely to affect patients’ use than clinical and demographic characteristics.
“We found that specific attitudes and beliefs — such as expectation of therapeutic benefits, patient-perceived barriers regarding cost and access, and opinions of patients’ physician and family members — may predict patients’ use of complementary and alternative medicine following cancer diagnoses,” said Dr. Mao. “We also found that these beliefs and attitudes varied by key socio-demographic factors such as sex, race, and education, which highlights the need for a more individualized approach when clinically integrating complementary and alternative medicine into conventional cancer care.”
The researchers noted that as therapies such as acupuncture and yoga continue to demonstrate clinical benefits for reducing pain, fatigue, and psychological distress, the field of integrative oncology is emerging to bring complementary and alternative medicine together with conventional care to improve patient outcomes. “Our findings emphasize the importance of patients’ attitudes and beliefs about complementary and alternative medicine as we seek to develop integrative oncology programs in academic medical centers and community hospitals,” said Dr. Bauml. “By aligning with patients’ expectations, removing unnecessary structural barriers, and engaging patients’ social and support networks, we can develop patient-centered clinical programs that better serve diverse groups of cancer patients regardless of sex, race, and education levels.”
And here is the abstract of the actual article:
Complementary and alternative medicine (CAM) incorporates treatments used by cancer survivors in an attempt to improve their quality of life. Although population studies have identified factors associated with its use, to the best of the authors knowledge, assessment of why patients use CAM or the barriers against its use have not been examined to date.
The authors conducted a cross-sectional survey study in the thoracic, breast, and gastrointestinal medical oncology clinics at an academic cancer center. Clinical and demographic variables were collected by self-report and chart abstraction. Attitudes and beliefs were measured using the validated Attitudes and Beliefs about CAM (ABCAM) instrument. This instrument divides attitudes and beliefs into 3 domains: expected benefits, perceived barriers, and subjective norms.
Among 969 participants (response rate, 82.7%) surveyed between June 2010 and September 2011, patient age ≤65 years, female sex, and college education were associated with a significantly greater expected benefit from CAM (P<.0001 for all). Nonwhite patients reported more perceived barriers to CAM use compared with white patients (P<.0001), but had a similar degree of expected benefit (P = .76). In a multivariate logistic regression analysis, all domains of the ABCAM instrument were found to be significantly associated with CAM use (P<.01 for all) among patients with cancer. Attitudes and beliefs regarding CAM explained much more variance in CAM use than clinical and demographic variables alone.
Attitudes and beliefs varied by key clinical and demographic characteristics, and predicted CAM use. By developing CAM programs based upon attitudes and beliefs, barriers among underserved patient populations may be removed and more patient centered care may be provided.
Why do I find this remarkable?
The article was published in the Journal CANCER, one of the very best publications in oncology. One would therefore expect that it contributes meaningfully to our knowledge. Remarkably, it doesn’t! Virtually every finding from this survey had been known or is so obvious that it does not require research, in my view. The article is an orgy of platitudes, and the press release is even worse.
But this is not what irritates me most with this paper. The aspect that I find seriously bad about it is its general attitude: it seems to accept that alternative therapies are a good thing for cancer patients which we should all welcome with open arms. The press release even states that, as therapies such as acupuncture and yoga continue to demonstrate clinical benefits for reducing pain, fatigue, and psychological distress, the field of integrative oncology is emerging to bring complementary and alternative medicine together with conventional care to improve patient outcomes.
I might be a bit old-fashioned, but I would have thought that, before we accept treatments into clinical routine, we ought to demonstrate that they generate more good than harm. Should we not actually show beyond reasonable doubt that patients’ outcomes are improved before we waffle about the notion? Is it not our ethical duty to analyse and think critically? If we fail to do that, we are, I think, nothing other than charlatans!
This article might be a mere triviality – if it were not symptomatic of what we are currently witnessing on a truly grand scale in this area. Integrative oncology seems fast to deteriorate into a paradise for pseudoscience and quacks.
Not much is known about the interactions of real doctors (by this I mean people who have been to medical school) and chiropractors who like to call themselves ‘doctors’ or ‘DCs’ but have never been to medical school. Therefore this recent article is of particular interest, in my view.
The purpose of this paper was to identify characteristics of Canadian chiropractors (DCs) associated with the number of patients referred by medical doctors (MDs). For this purpose, secondary data analyses were performed on the 2011 cross-sectional survey of the Canadian Chiropractic Resources Databank survey which included 81 questions about the practice of DCs. Of the 6533 mailed questionnaires, 2529 (38.7%) were returned and 489 did not meet our inclusion criteria. In total, the analysed sample included 2040 respondents.
The results show that, on average, DCs reported receiving 15.6 (SD 31.3) patient referrals from MDs per year. Nearly one-third of the respondents did not receive any. The type of clinic (multidisciplinary with MD), the province of practice (Atlantic provinces), the number of treatments provided per week, the number of practicing hours, rehabilitation and sports injuries as the main sector of activity, prescription of exercises, use of heat packs and ultrasound, and the percentage of patients referred to other health care providers were associated with a higher number of MD referrals to DCs. The percentage of patients with somatovisceral conditions, using a particular chiropractic technique (hole in one and Thompson), taking own radiographs, being the client of a chiropractic management service, and considering maintenance/wellness care as a main sector of activity were associated with fewer MD referrals.
The authors concluded that Canadian DCs who interacted with other health care workers and who focus their practice on musculoskeletal conditions reported more referrals from MDs.
One could criticise this survey for a number of reasons, for instance:
- the response rate was low,
- the sample was small,
- the data are now 4 years old and might be obsolete.
Despite these flaws, the paper does seem to reveal some relevant things. What I find especially interesting is that:
- the level of referrals from doctors to chiropractors seems exceedingly low,
- dubious chiropractic activities such as maintenance therapy or treatment of non-spinal conditions led to even less referrals.
To me, that implies that Canadian doctors are, on the one hand, willing to co-operate with chiropractors. On the other hand, they remain cautious about the high level of quackery in this profession.
All this means really is that Canadian doctors are responsible and aim to adhere to evidence-based practice…in contrast to many chiropractors, I hasten to add.
The principal aim of this survey was to map centres across Europe that provide public health services and operating within the national health system in integrative oncology.
Information was received from 123 (52.1 %) of the 236 centres contacted. Forty-seven out of 99 responding centres meeting inclusion criteria (47.5 %) provided integrative oncology treatments, 24 from Italy and 23 from other European countries. The number of patients seen per year was on average 301.2 ± 337. Among the centres providing these kinds of therapies, 33 (70.2 %) use fixed protocols and 35 (74.5 %) use systems for the evaluation of results. Thirty-two centres (68.1 %) were research-active.
The alternative therapies most frequently provided were acupuncture 26 (55.3 %), homeopathy 19 (40.4 %), herbal medicine 18 (38.3 %) and traditional Chinese medicine 17 (36.2 %); anthroposophic medicine 10 (21.3 %); homotoxicology 6 (12.8 %); and other therapies 30 (63.8 %).
Treatments were mainly directed to reduce adverse reactions to chemo-radiotherapy (23.9 %), in particular nausea and vomiting (13.4 %) and leucopenia (5 %). The alternative treatments were also used to reduce pain and fatigue (10.9 %), to reduce side effects of iatrogenic menopause (8.8 %) and to improve anxiety and depression (5.9 %), gastrointestinal disorders (5 %), sleep disturbances and neuropathy (3.8 %).
The authors concluded that mapping of the centres across Europe is an essential step in the process of creating a European network of centres, experts and professionals constantly engaged in the field of integrative oncology, in order to increase, share and disseminate the knowledge in this field and provide evidence-based practice.
WHAT EVIDENCE-BASED PRACTICE?
Where is the evidence that homeopathy or homotoxicology or Chinese medicine are effective for any of the conditions listed above? The answer, of course, is that it does not exist.
I fear the results of this survey show foremost one thing: ‘integrative oncology’ is little else but a smokescreen behind which quacks submit desperate patients to bogus treatments.
Chiropractors like to promote themselves as primary healthcare professionals. But are they? A recent survey might go some way towards addressing this question. It was based on a cross sectional online questionnaire distributed to 4 UK chiropractic associations. The responses were collected over a period of two months from March 26th 2012 to May 25th 2012.
Of the 2,448 members in the 4 participating associations, 509 chiropractors (~21%) completed the survey. The results of the survey show that the great majority of UK chiropractors surveyed reported evaluating and monitoring patients in regards to posture (97.1%), inactivity/overactivity (90.8%) and movement patterns (88.6%). Slightly fewer provided this type of care for psychosocial stress (82.3%), nutrition (74.1%) and disturbed sleep (72.9%). Still fewer did so for smoking (60.7%) and over-consumption of alcohol (56.4%). Verbal advice given by the chiropractor was reported as the most successful resource to encourage positive lifestyle changes as reported by 68.8% of respondents. Goal-setting was utilised by 70.7% to 80.4% of respondents concerning physical fitness issues. For all other lifestyle issues, goal-setting was used by approximately two-fifths (41.7%) or less. For smoking and over-consumption of alcohol, a mere one-fifth (20.0% and 20.6% respectively) of the responding chiropractors set goals.
The authors of this survey concluded that UK chiropractors are participating in promoting positive lifestyle changes in areas common to preventative healthcare and health promotion areas; however, more can be done, particularly in the areas of smoking and over-consumption of alcohol. In addition, goal-setting to support patient-provider relationships should be more widespread, potentially increasing the utility of such valuable advice and resources.
When I saw that a new UK-wide survey of chiropractic has become available, I had great expectations. Sadly, they were harshly disappointed. I had hoped that, after going to the considerable trouble of setting up a nationwide survey of this nature, we would have some answers to the most urgent questions that currently plague chiropractic and are amenable to study by survey. In my view, some of these questions include:
- How many chiropractors actually see themselves as primary care professionals?
- What conditions do chiropractors treat?
- Specifically how many of them believe they can treat non-spinal conditions effectively?
- How many chiropractors regularly treat children?
- For which conditions?
- How many patients get X-rayed by chiropractors?
- How many are in favour of vaccinations?
- How many are aware of adverse effects of spinal manipulation?
- How chiropractors obtain informed consent before starting treatment?
- What percentage of chiropractors use spinal manipulation?
- What other treatments are used how often?
- How often do chiropractors advise their patients about medications prescribed by real doctors?
- How often do they refer patients to other health care providers?
All of these questions are highly relevant and none of them has recently been studied. But, sadly, the new paper does not answer them. Why? As I see it, there are several possibilities:
- Chiropractors do not find these questions as relevant as I do.
- They do not want to know the answers.
- They do not like to research issues that might shine a bad light on them.
- They view research mostly as a promotional exercise.
- They did research (some of) these questions but do not dare to publish the results.
- They will publish the results in a separate paper.
It would be interesting to hear from the authors which possibility applies.
How often have we heard it on this blog and elsewhere?
- chiropractic is progressing,
- chiropractors are no longer adhering to their obsolete concepts and bizarre beliefs,
- chiropractic is fast becoming evidence-based,
- subluxation is a thing of the past.
American chiropractors wanted to find out to what extent these assumptions are true and collected data from chiropractic students enrolled in colleges throughout North America. The stated purpose of their study is to investigate North American chiropractic students’ opinions concerning professional identity, role and future.
A 23-item cross-sectional electronic questionnaire was developed. A total of 7,455 chiropractic students from 12 North American English-speaking chiropractic colleges were invited to complete the survey. Survey items encompassed demographics, evidence-based practice, chiropractic identity and setting, and scope of practice. Data were collected and descriptive statistical analyses were performed.
A total of 1,243 questionnaires were electronically submitted. This means the response rate was 16.7%. Most respondents agreed (34.8%) or strongly agreed (52.2%) that it is important for chiropractors to be educated in evidence-based practice. A majority agreed (35.6%) or strongly agreed (25.8%) the emphasis of chiropractic intervention is to eliminate vertebral subluxations/vertebral subluxation complexes. A large number of respondents (55.2%) were not in favor of expanding the scope of the chiropractic profession to include prescribing medications with appropriate advanced training. Most respondents estimated that chiropractors should be considered mainstream health care practitioners (69.1%). About half of all respondents (46.8%) felt that chiropractic research should focus on the physiological mechanisms of chiropractic adjustments.
The authors of this paper concluded that the chiropractic students in this study showed a preference for participating in mainstream health care, report an exposure to evidence-based practice, and desire to hold to traditional chiropractic theories and practices. The majority of students would like to see an emphasis on correction of vertebral subluxation, while a larger percent found it is important to learn about evidence-based practice. These two key points may seem contradictory, suggesting cognitive dissonance. Or perhaps some students want to hold on to traditional theory (e.g., subluxation-centered practice) while recognizing the need for further research to fully explore these theories. Further research on this topic is needed.
What should we make of these findings? The answer clearly must be NOT A LOT.
- the response rate was dismal,
- the questionnaire was not validated
- there seems to be little critical evaluation or discussion of the findings.
If anything, these findings seem to suggest that chiropractors want to join evidence based medicine, but on their own terms and without giving up their bogus beliefs, concept and practices. They seem to want the cake and eat it, in other words. The almost inevitable result of such a development would be that real medicine becomes diluted with quackery.
Complementary treatments have become a popular (and ‘political correct’) option to keep desperate cancer patients happy. But how widely accepted is their use in oncology units? A brand-new article tried to find the answer to this question.
The principal aim of this survey was to map centres across Europe prioritizing those that provide public health services and operating within the national health system in integrative oncology (IO). A cross-sectional descriptive survey design was used to collect data. A questionnaire was elaborated concerning integrative oncology therapies to be administered to all the national health system oncology centres or hospitals in each European country. These institutes were identified by convenience sampling, searching on oncology websites and forums. The official websites of these structures were analysed to obtain more information about their activities and contacts.
Information was received from 123 (52.1 %) out of the 236 centres contacted until 31 December 2013. Forty-seven out of 99 responding centres meeting inclusion criteria (47.5 %) provided integrative oncology treatments, 24 from Italy and 23 from other European countries. The number of patients seen per year was on average 301.2 ± 337. Among the centres providing these kinds of therapies, 33 (70.2 %) use fixed protocols and 35 (74.5 %) use systems for the evaluation of results. Thirty-two centres (68.1 %) had research in progress or carried out until the deadline of the survey. The complementary and alternative medicines (CAMs) more frequently provided to cancer patients were acupuncture 26 (55.3 %), homeopathy 19 (40.4 %), herbal medicine 18 (38.3 %) and traditional Chinese medicine 17 (36.2 %); anthroposophic medicine 10 (21.3 %); homotoxicology 6 (12.8 %); and other therapies 30 (63.8 %). Treatments are mainly directed to reduce adverse reactions to chemo-radiotherapy (23.9 %), in particular nausea and vomiting (13.4 %) and leucopenia (5 %). The CAMs were also used to reduce pain and fatigue (10.9 %), to reduce side effects of iatrogenic menopause (8.8 %) and to improve anxiety and depression (5.9 %), gastrointestinal disorders (5 %), sleep disturbances and neuropathy (3.8 %).
As so often with surveys of this nature, the high non-response rate creates a problem: it is not unreasonable to assume that those centres that responded had an interest in IO, while those that failed to respond tended to have none. Thus the figures reported here for the usage of alternative therapies might be far higher than they actually are. One can only hope that this is the case. The idea that 40% of all cancer patients receive homeopathy, for instance, is hardly one that is in accordance with the principles of evidence-based practice.
The list of medical reasons for using largely unproven treatments is interesting, I think. I am not aware of lots of strong evidence to show that any of the treatments in question would generate more good than harm for any of the conditions in question.
What follows from all of this is worrying, in my view: thousands of desperate cancer patients are being duped into having bogus treatments paid for by their national health system. This, I think, begs the question whether these most vulnerable patients do not deserve better.
