Statements circulated by dozens of Manitoba chiropractors are misleading and potentially harmful, says a public health expert.
"There is no evidence that chiropractic is effective in treating cancer and autism and any of those things that they are apparently claiming that they can treat," said Dr. Alan Katz, director of the Manitoba Centre for Health Policy.
A CBC News analysis of company websites and Facebook pages of every registered chiropractor in Manitoba found several dozen examples of statements, claims and social media content at odds with many public health policies or medical research.
- Offers of treatments for autism, Tourette's syndrome, Alzheimer's disease, colic, infections and cancer.
- Anti-vaccination literature and recently published letters to the editor from chiropractors that discourage vaccination.
- An article claiming vaccines have caused a 200 to 600 per cent increase in autism rates.
- A statement that claims the education and training of a chiropractor is "virtually identical" to that of a medical doctor.
- Discouraging people from getting diagnostic tests such as CT scans, colonoscopies and mammograms.
- An informational video discouraging the use of sunscreen.
Dr. Katz reviewed the examples gathered by the CBC I-Team and labelled most of them "misinformation."
"It misleads the public in two areas. Firstly, those who choose to go for chiropractic care, particularly for things like infection and autism and things that we know they're not going to be beneficial for, it misleads those individuals and gives them false hope for treatment that will not be effective," he said.
"Putting these things up on their website also puts the doubt in the minds of others about what we do know works, and as a result those people may not seek the right type of care for conditions that could deteriorate if they don't seek that care."
Vaccination and immunizations outside scope of practice
The Manitoba Chiropractors Association declined an interview request but did say it would review the content.
The Manitoba Chiropractors Association has previously addressed certain issues with its membership through an internal communication.
"In Manitoba, the administration of 'vaccination and immunization' currently falls outside the scope of chiropractic practice," the communication said. It also cautioned members that:
- "Chiropractors may be liable for opinions they provide to patients/public in circumstances where it would be reasonably foreseeable that the individual receiving the opinion would rely on it.
- "Providing professional opinions on the issue of vaccination and immunization would likely be found by a court to be outside the scope of practice of a chiropractor."
The association also said, "The degree to which a chiropractor can or cannot discuss 'vaccination and immunization' or other health-care procedures that are outside the scope of practice with a patient is currently being reviewed by the board of directors."
CBC News reached out to several chiropractors for comment about their online content. Calls and emails were either not returned, or interview requests were declined.
'We encourage Manitobans to get vaccinated': province
Manitoba is the only province in the country that universally covers a portion of chiropractic treatments for all residents, to a limit of 12 visits per year.
The fact that members of a regulated health profession are actively disseminating questionable medical information while benefiting from public funds is cause for concern, Katz said.
"Should we as a society be paying for the services of professionals, and I use that word loosely, that are advocating care that is contrary to the official public policy?"
Manitoba's health minister didn't comment on the issue, but Manitoba Health provided a statement after it was given examples of the information.
Anti-vax letters to the editor prompted CBC investigation
A letter by Winnipeg chiropractor Henri Marcoux was published last February in Manitoba's francophone weekly newspaper La Liberté, in response to an article in which a regional health authority expert was interviewed about influenza immunizations.
Marcoux wrote that he does not recommend flu vaccines, calling them "toxic." He further stated that the flu virus actually "purifies our systems" and said that he believes flu vaccines are "driven by a vast operation orchestrated by pharmaceutical companies."
People should instead focus on general wellness — which includes chiropractic treatment — to stave off the flu, he wrote.
Now-retired chiropractor and long-time anti-vaccination advocate Gérald Bohémier wrote a later letter in support of Marcoux that also appeared in La Liberté.
- Chiropractic neck procedures cause strokes, say survivors
- Manitoba clinic avoiding opioids in chronic pain management
Letters then poured in from members of the community, including a resident and two physicians who took exception to these statements.
Marcoux told the CBC's French service, Radio-Canada, that he does not believe his views are at odds with public health.
He stands by his letter, he said, adding if society as a whole took health and wellness more seriously — rather than trying to treat symptoms — the need for vaccines would dissipate or never would have existed in the first place.
