“They would say that, wouldn’t they?” is the quote attributed to Mandy Rice-Davies giving witness in the Profumo affair. I think, it aptly highlights some of the issues related to conflicts of interest in health care.
These days, when a researcher publishes a paper, he will in all likelihood have to disclose all conflicts of interest he might have. The aim of this exercise is to be as transparent as possible; if someone has received support from a commercial company, for example, this fact does not necessarily follow that his paper is biased, but it is important to lay open the fact so that the readers can make up their own minds.
The questionnaires that authors have to complete prior to publication of their article focus almost exclusively on financial issues. For instance, one has to disclose any sponsorship, fees, travel support or shares that one might own in a company. In conventional medicine, these matters are deemed to be the most important sources for potential conflicts of interest.
In alternative medicine, financial issues are generally thought to be far less critical; it is generally seen as an area where there is so little money that it is hardly worth bothering. Perhaps this is the reason why few journals in this field insist on declarations of conflicts of interests and few authors disclose them.
After having been a full-time researcher of alternative medicine for two decades, I have become convinced that conflicts of interest are at least as prevalent and powerful in this field as in any other area of health care. Sure, there is less money at stake, but this fact is more than compensated by non-financial issues. Quasi-evangelic convictions abound in alternative medicine and it is, I think, obvious that they can amount to significant conflicts of interest.
During their training, alternative practitioners are being taught many things which are unproven, have no basis in fact or are just plainly wrong. Eventually this schooling can create a belief system which often is adhered to regardless of the scientific evidence and which tends to be defended at all cost. As some of my readers are bound to object to this remark, I better cite an example: during their training, students of chiropractic develop a more and more firm stance against immunization which in all likelihood is due to the type of information they receive at the chiropractic college. There is no question in my mind that creeds can represent an even more powerful conflict of interest than financial matters.
Moreover, this belief is indivisibly intertwined with existential issues. In alternative medicine, there may not be huge amounts of money at stake but practitioners’ livelihoods are perceived to be at risk. If an acupuncturist, for instance, argues in favour of his therapy, he also consciously or sub-consciously is trying to protect his income.
Some might say that this not different from conventional medicine, but I disagree: if we take away one specific therapy from a doctor because it turns out to be useless or unsafe, he will be able to use another one; if we take the acupuncture needle away from an acupuncturist, we have deprived him of his livelihood.
This is why conflicts of interest in alternative medicine tend to be very acute, powerful and personal. And this is why enthusiasts of alternative medicine are incapable or unwilling to look upon any type of critical assessment of their area as anything else than an attack on their income, their beliefs, their status, their training or their person. If anyone should doubt it, I recommend studying the comments I received to previous posts of this blog.
When Mandi Rice-Davies gave evidence during the trial of Stephen Ward, the osteopath who had introduced her to influential clients, the prosecuting council noted that Lord Astor denied having had an affair with her. Mrs Rice-Davies allegedly replied “Well, he would say that, wouldn’t he?” (Actually, she did not say these exact words but something rather similar) When I read the comments following my posts on this blog, I am often reminded of this now classical quote.
When chiropractors deny that neck manipulations carry a risk, when herbalists insist that traditional herbalism is based on good evidence, when homeopaths claim that their remedies are more than placebos, I believe we should ask who, in these debates, might have a conflict of interest.
Is there a circumstance of one party in the discussion where personal interests might benefit from the argument? Who is more likely to be objective, the person whose livelihood is endangered or the independent expert who studied the subject in depth but has no axe to grind? If you ask these questions, you might conclude as I frequently do: “they would say that, wouldn’t they?”
