Sadly, the Washington Post once again falls for acupuncture pseudoscience

It’s like playing whac-a-mole. No matter how many times I write a column showing that some wildly implausible practice is nonsense, new articles pop up claiming “Hey, look at this! It really works!”

So I’m going to try to whack another mole, because people can be harmed by bad information, especially when it comes in the form of medical advice.

Recently the Washington Post ran a column under the headline, “Does acupuncture work for chronic pain? Here’s what the science says.” (The column first appeared back in July, but the Post’s website promoted it again just last week.)

Before giving you the Post’s answer, let me give you the correct answer. No! Not “maybe” or “sometimes” or “we’re not sure.” Acupuncture doesn’t treat anything, and it carries a real risk of harm, particularly from infections. I’ll get to that below.

I’ve written on this topic many times before (in 2013, in 2012, in 2010, and more), and I’ve even called out the Washington Post for their pro-acupuncture pseudoscience (see this column, which I wrote in 2016). The physicians over at Science-Based Medicine have debunked more acupuncture studies than I can count; they’ve even created a special webpage (which I highly recommend) dedicated to explaining the bogus claims that acupuncture proponents make.

Acupuncture, in case you don’t know this, is a practice where people who call themselves acupuncturists (they are not doctors) stick needles into your body to “treat” various conditions. The claim is that these needles can manipulate your vital life force, or “qi”, which runs along supposed acupuncture lines throughout your body.

That’s just wrong. Modern biology has taught us a whole lot about human physiology, and there just aren’t any lines with mystical forces flowing through them. There are nerve fibers, true, but acupuncturists don’t use those. (And if their needles were piercing nerves, it would hurt like heck.)

Acupuncture and qi are part of Traditional Chinese Medicine, or TCM, a collection of largely ineffective and sometimes very harmful folk beliefs. TCM’s popularity started to grow in the mid-20th century when Chairman Mao launched a propaganda campaign pushing it. Mao himself never used TCM, but his government couldn’t afford real medicine, so they convinced people that inexpensive folk medicine was just as good. It wasn’t.

But I digress.

Acupuncturists claim to treat many conditions, but they especially like to claim that they can treat chronic pain, for at least a couple of reasons. First, pain is inherently subjective, so the only way to measure if a treatment is working is to ask the patient. This makes it hard to study objectively. And second, pain symptoms usually wax and wane, even without any treatment. Patients usually want treatment when the pain is at its worst, which means once the pain subsides, the patients will give credit to whatever they were doing at that time. So pain is fertile ground for people selling quack treatments.

Now let’s get to that column in the Washington Post. The column promises to tell you “what the science says,” and it quickly gets to the point, saying yes, it does! First it puts forward the logically flawed (and non-scientific) claim that hey, the U.S. Medicare system now covers acupuncture for back pain, so it must be effective.

Ugh, where do I start? Well, like it or not, Medicare approval of a treatment doesn’t mean the treatment works. (And conversely, some treatments that work are approved for coverage by Medicare.) So that’s just a logical fallacy. I wish it were true that Medicare was purely science-driven, but both the federal and state government have been lobbied for years by acupuncturists (and other purveyors of dubious therapies) to provide public tax dollars to cover their practices. For a deeper dive into these lobbying efforts, I recommend the lengthy takedown by Jann Bellamy explaining that acupuncture is “legalized quackery.”

The Post article then goes on to discuss the science, for which it relies primarily on a single study, a meta-analysis published in 2019 by Andrew Vickers. (The column was written by Dr. Trisha Pasricha, who has sterling credentials, including training at Johns Hopkins Medicine where I also work. Alas, good credentials don’t always mean that you can trust the holder of those credentials, and this is one of those instances.)

Vickers has published multiple meta-analyses, and if he’s shown anything, it’s how easy it is to cherry-pick from the (extensive) acupuncture literature and find studies that prove whatever point you want to make. The Post column asserts that Vickers used 39 “high-quality” studies, but that is debatable. Many of the studies were done in China, which (as Science-Based Medicine physicians David Gorksi and Steven Novella have pointed out) virtually never publishes a negative study of acupuncture.

I’ve done a deep dive into one of Vickers meta-analyses of acupuncture–an earlier one–for one of my medical school classes, where I use it to illustrate how bad studies can be mis-reported by scientists themselves and by the media. I don’t have time to go through it here, but among other problems, Vickers doesn’t seem to understand how placebo controls work.

Here’s what I mean by cherry-picking. Vickers went through 100’s of studies to pick the 39 that he included. One of those supposedly high-quality studies looked at acupuncture for knee arthritis. That study found that both acupuncture and sham acupuncture (the placebo arm) and the same small effect on knee pain, and that patients who received no treatment at all reported more pain than patients. The authors of the study (and Vickers) concluded–wrongly–that because acupuncture was better than nothing, it must be working. Wrong! If you don’t beat the placebo, then your treatment fails.

For a drug trial, failing to beat the placebo means the game is over. But with acupuncture, it means “more studies are needed,” and the whac-a-mole game continues.

Oh, and I should add that as far as knee arthritis goes, the reduction in pain in both the acupuncture and placebo group was much less than has been reported in studies that use ibuprofen.

That’s right, ibuprofen is far better than acupuncture. Not to mention cheaper and more convenient.

If this weren’t enough, a more recent study has already contradicted the Vickers study as physician-blogger Steven Novella pointed out in a recent column. Novella wrote that “the evidence is too low quality to conclude that acupuncture works, as desperate as proponents are to say we can reach that conclusion.” So no, Dr. Pasricha, the latest science does not say that acupuncture works. Quite the opposite.

I’m still understating how badly acupuncture has failed every well-designed study to test its effectiveness. Studies have shown that placing the needles in random locations works just as well as using so-called acupuncture points. Other studies showed that sham acupuncture, where the needles don’t pierce the skin but where subjects believe they did, also works just as well. And “expert” acupuncturists can’t agree on the locations of acupuncture points.

And don’t get me started on acupuncture and the risk of infection. Acupuncturists aren’t trained in real medicine, and they don’t use proper sterile procedures. This means that they don’t necessarily sterilize their hands, or your skin at all of those points where they’re plunging needles into you. There have been thousands reports of infections due to acupuncture (dating back decades), some of them fatal. And because acupuncturists aren’t part of the medical system, we can be virtually certain that infections are under-reported.

Acupuncture isn’t going away any time soon, because people are making money from it, and no matter how many studies show that it’s nothing more than a fiction, those people will keep insisting on more studies. Plus they can point to hundreds of poorly-done studies that claim to show benefits, and argue–as the Post column does too–that “more research is needed.” I’m not making this up: that precise phrase appears in Dr. Pasricha’s article.

There are even scientific journals entirely devoted to acupuncture (here and here, for example), and they make money too, for the for-profit publishers that produce them. So you can be sure that more studies are coming, and some of them will be positive, even though acupuncture is utterly ineffective.

Even so, the Washington Post can and should do better. Here’s my (free) advice for those considering acupuncture: save your money, and just take some ibuprofen.

Washington Post's Science section descends into pseudoscience

The Washington Post has some bad news about migraines.
Every Tuesday, the Washington Post has a special section devoted to Health and Science. It’s usually my favorite section, with features such as “medical mysteries” and highlights of the latest news from the world of science.

Not this week. Instead, the front page of the section featured a lengthy article that was a long anecdote by a woman who firmly believes that acupuncture cured her migraines. The title gave me a feeling of dread: “Acupuncture needles stung, but they cured my migraines” (the online version linked here has a different title). As I feared, there wasn't a whit of science in it.

Let’s get one thing out of the way first: acupuncture is rank pseudoscience. It’s based on a primitive, pre-scientific notion of a “vital force” (for which no evidence exists), usually called qi, that runs through the body along meridians (no evidence for these either). Plunging needles into the meridians is supposed to manipulate this vital force and cure all sorts of things, ranging from pain to infections to cancer. All of this is nonsense. If you want to know more, I recommend Acupuncture Watch; or see Ben Kavoussi’s article explaining how postmodernism, with its notion that all truth is relative, has allowed acupuncture and other mystical, archaic beliefs to gain traction in medical practice; or check out Jann Bellamy’s discussion of acupuncture as “legalized quackery”.

I’ve written about the nonsense that is called acupuncture before (in 2013, and in 2012, and in 2010), so I won’t rehash that here. But it’s really disheartening to see a great (or once-great?) newspaper devote a large chunk of its weekly science section to pseudoscience.

Back to this week’s nonsense article. In this lengthy piece, author Margarita Gokun Silver describes how she began to experience debilitating migraines after the age of 40, which grew worse over time. She tried pain relievers, which worked at first but then stopped working. One expensive pill worked for the migrations but gave her severe nausea. Eventually, she writes, “exhausted by these side effects, I turned again to the Internet.”

Great. Now, there’s nothing wrong with looking for solutions in the Internet–we all do it. But this is an article in the Washington Post Science section! Nowhere does the author describe anything resembling actual science. Instead, she describes how she discovered a “breakthrough” in her yoga class, when another yoga student suggested acupuncture. She decided to give it a try.

(You might be wondering, who is Margarita Gokun Silver? She describes herself as a writer, novelist, and painter–not a scientist or a doctor.)

After several acupuncture sessions, the author tells us, her migraines seemed less frequent, and eventually she decided she was cured. She still gets migraines, but when they get bad she uses acupuncture again. This, she tells us, is her cure.

The entire story is a classic example of how we can fool ourselves into thinking that whatever we tried last is what worked. Migraines come and go, and this woman’s story is not unusual. She had a long series of bad migraines that eventually subsided, and she still gets them. When they were at their worst, she tried everything she could find, and when the episodes became less frequent, she gave full credit to acupuncture. She might just as well have tried chocolate milk, and then written an article claiming “chocolate milk cured my migraines!”

I don’t blame the author (well, not much) for wrongly believing that correlation equals causation. But we have scientific methods that are really, really good at figuring out if a treatment works. Scientists have already looked at this particularly claim, and the bottom line is that acupuncture doesn’t cure migraines. If you don’t believe me, then read the article about treating migraines by Dr. Steven Novella, a Yale neurologist who specializes in headaches, and look at his summary of how not to treat migraines, which points out that
“acupuncture proponents have been able to change the rules of clinical research so that essentially negative or worthless studies of acupuncture are presented as positive.”
Last week's Washington Post Science section was a major fail. I can't imagine why they gave a lengthy forum to a non-scientist to write about pseudoscience. If they wanted to feature a story about migraines, there's plenty of good science out there, even if there's no magical cure. What's next, Washington Post? Will you invite Jenny McCarthy to write about vaccines and autism, or Gwyneth Paltrow to discuss detox treatments? I sure hope not.

Medicare data reveals that U.S. wastes half a billion dollars per year on chiropractic

Hold on, you're about to get "adjusted."
Ten days ago, the federal government released a huge data set detailing how it spent $77 billion in Medicare funds in 2012 to over 880,000 health care providers. The release of this data is part of a new transparency effort by the government, which many of us applaud.

The data reveal some troubling things.

Most news organizations focused on who the biggest beneficiaries are: the New York Times described how just 100 doctors received $610 million. A Washington Post story focused on the top 10 Medicare billers, including one ophthalmologist in Florida who was paid $20 million by Medicare, mostly to cover Lucentis, a drug for macular degeneration. The Post pointed out that Medicare would have saved over $10 million if that doctor used Avastin, which is equally effective. “Medicare pays a doctor more for injecting the more expensive drug,” the Post pointed out.

But until now, no one has pointed out another, far more egregious waste revealed by the Medicare data: we are spending a huge amount of money on the highly dubious practice known as chiropractic.

To be precise, the 2012 Medicare data reveals that in 2012, Medicare paid $496 million for chiropractic.

This is a stunning amount. It dwarfs the funding that NIH wastes on alternative medicine through NCCAM, which is itself an egregious waste of money.

Chiropractors are not medical doctors. They primarily treat back pain, but they claim to treat a wide range of other conditions, which some of them believe are related to mis-alignments of the spine, called subluxations. This belief has no scientific basis. Nevertheless, chiropractors have succeeded in convincing the government to cover their treatments through Medicare.  

Now we know how successful they have been: half a billion dollars a year spent “adjusting” the spines of patients, all funded by Medicare.

(And they have recently been lobbying furiously, as I wrote last summer, to force private health care providers to cover chiropractic and other alternative practices under Obamacare.)

But wait, you might ask, don’t chiropractors provide pain relief? And don’t they have medical degrees? Well, on the second question, the answer is that they have special Doctor of Chiropractic (D.C.) degrees, which are given out by just 15 special chiropractic colleges in the U.S. The entire field was invented out of thin air by D.D. Palmer in 1895, and later popularized by his son. In his book-length expose Chiropractic Abuse: An Insider's Lament, chiropractor Preston Long lists "20 things most chiropractors won't tell you," including
  1. "Chiropractic theory and practice are not based on ... knowledge related to health, disease, and health care. 
  2. Many chiropractors promise too much.
  3. Our education is vastly inferior to that of medical doctors."
These are just the first three: you can see the full list in a review of Long's book by physician Harriet Hall, or read the book itself.

Sam Homola, a retired chiropractor, summarized his concerns about chiropractic in an article at Science-Based Medicine. Homola concluded that 
“There is no credible evidence to support the use of spinal manipulation for anything other than uncomplicated mechanical-type back pain and … no evidence at all to support chiropractic subluxation theory.”
Perhaps most alarming, especially given that Medicare is paying for millions of treatments per year, is that chiropractic manipulation can cause a stroke, by causing a tear in a major artery running through the neck. As reported recently in the Journal of Neurosurgery:
“Chiropractic manipulation of the cervical spine can produce dissections ... of the vertebral and carotid arteries. These injuries can be severe, requiring endovascular stenting and cranial surgery. In this patient series, a significant percentage (31%, 4/13) of patients were left permanently disabled or died as a result of their arterial injuries.” [Albuquerque et al., J. Neurosurg 2011 115(6):1197-1205]
If this weren’t enough to cause concern, many chiropractors are also anti-vaccine, a problem that is apparently serious enough that some chiropractors themselves have spoken out against the anti-vaxxers in their own ranks.

Over a century ago, D.D. Palmer believed, mistakenly, that he cured a man’s deafness by manipulating his neck. His son built Palmer’s beliefs into a profitable business, but neither of them would have dreamed that the U.S. government would one day spend half a billion dollars per year on chiropractic manipulations. 

If we want to start controlling the cost of Medicare, here’s an easy first step: stop covering chiropractic. We will save $496 million a year, and people’s health will improve.

Stabbing kids with needles: malpractice, or just a very bad idea?


Yesterday's Washington Post featured a terribly researched article titled "Kids and needles is sometimes a good match: Acupuncture can help with pain."

Imagine: a one-year-old boy arrives at an emergency room in New York at 3 a.m. with an asthma attack.  He is slow to respond to a nebulizer treatment.  Enter Dr. Stephen Cowan, who decides to use acupuncture.  That's right, he stabs a one-year-old baby with multiple needles to treat asthma.  According to Dr. Cowan, the boy "reacted calmly" and improved.  The article doesn't provide any more details.

This is appalling.  Sticking needles into a baby has never been shown to have any effectiveness at treating asthma, and we do have treatments that work.  In all likelihood, the nebulizer did work, in the case that Dr. Cowan related to the reporter, but Dr. Cowan mistakenly credits his acupuncture treatment.

Stephen Cowan is a aggressively self-promoting doctor, who claims on his website that he can treat both autism and ADHD with acupuncture and other forms of Chinese Medicine.  He also describes how he convinces children to let him stick needles into them.  He states his belief in mystical "vital energy" or qi, one of the wacky pseudoscientific notions at the core of acupuncture beliefs.  His claims are little more than a modern, mystical version of the claims made by 19th-century snake oil salesman.

The Washington Post story also revealed that Children's National Medical Center in Washington, D.C. recently treated a 17-year-old girl with pancreatitis by stabbing needles into her stomach and other places.  There is no evidence that this works, but the girl's doctor believes it does.  The girl reportedly wasn't harmed, fortunately.

The doctor at Children's Hospital, Jennifer Anderson, is an anesthesiologist who is also an acupuncturist.  In the story, she said "I often treat patients with chronic issues" with acupuncture.  This is frightening: a doctor at a major medical center is telling children, most of whom are too young to even think of questioning the wisdom of a doctor, that sticking them with needles will help their pain.  Dr. Anderson admitted that "she often does two to three treatments a week at first on a child."  So she admits to stabbing many sharp needles into children and telling them that the treatments will help their pain.  She argues that the children report that this is "helpful."

This is perilously close to child abuse.  Children want to please adults, and if an adult tells them something is good for them, especially if an authority figure tells them, they are extremely unlikely to disagree. They'll just swallow the medicine, or endure the treatment, and then tell the adult what she wants to hear.  Dr. Anderson seems unaware of this.  And Children's National Medical Center, a generally outstanding hospital, should be seriously concerned that one of its anesthesiologists is practicing quack medicine on children, who are perhaps the most vulnerable of all patients.

Let's be clear: acupuncture is based on nonsense.  Scientists have gone to great pains to study it, and the conclusion can be stated simply: acupuncture does not work.  (And yes, I know about the latest meta-analysis claiming that acupuncture works.  Dr. Steven Novella has already explained why that analysis is "completely useless.")  If acupuncture were a drug being tested by a pharmaceutical company, it would have been abandoned long ago.  Its proponents are no better than any big pharma company that pushes a drug that it knows to be ineffective.

Acupuncture is worse than ineffective: because it's an invasive procedure, there is a small but real risk of harm.  As I wrote last year in The Atlantic, acupuncturist sometimes cause infections, which can lead to rare but serious complications.  Acupuncturists protest (often) that they use sterile needles, but this very protest reveals their ignorance: most infections are caused by bacteria already present on the skin, which enter through the puncture wound.

Parents: don't let an acupuncturist stick needles into your kids.  Read the science first, and avoid - no, run screaming from - any practitioner who claims that he can adjust the "qi" in your child.
