Answering Our Critics, Part 1 of 2

Some people don’t like what we have to say on Science-Based Medicine. Some attack specific points while others attack our whole approach. Every mention of complementary and alternative medicine (CAM) elicits protests in the Comments section from “true believer” users and practitioners of CAM. Every mention of a treatment that has been disproven or has not been properly tested elicits testimonials from people who claim to have experienced miraculous benefits from that treatment. In previous articles I have compiled the criticisms of what I wrote about Protandim and Isagenix. It’s instructive to read through them. We welcome rational and substantive criticism, but most of these comments are neither.

Our critics keep bringing up the same old memes, and it occurred to me that rather than try to answer them each time, it might be useful to list those criticisms and answer them here. In future, when the same points are raised, we could save time and effort by linking to this page and citing the reference number. I know this list is not comprehensive, and I hope our readers will point out anything I’ve omitted. Here are some of the criticisms we keep hearing:

1. Big Pharma is paying you to promote their products and discredit CAM.

No it isn’t. We are not Pharma shills. We are not paid anything for writing this blog. We do not get money from pharmaceutical companies. We do not accept gifts from drug companies. We do not get kickbacks for prescribing certain drugs. We have no incentive to favor drugs over other treatments. Incidentally, critics who prefer natural remedies to pharmaceuticals should note that many CAM diet supplements are sold by subsidiaries of Big Pharma. (more…)

“How do you feel about Evidence-Based Medicine?”

That was the question asked on a Medscape Connect discussion

I did a double-take. How do you feel? Could anybody object to the idea of basing treatments on evidence? The doctor who started the discussion asked:

Besides using EBM, a lot of my prescribing comes from anecdotal experience and intuition. How about you? Where do you get your information from that you use to treat your patients? Do you always ascribe to EBM, or do you deviate from it with certain medical conditions/patients?

I had naively thought that my profession uniformly embraced EBM. How could they not? The commenters broke my bubble big-time. Some of them summarily reject EBM… although it appears that what they are rejecting is not what I understand EBM to mean. (more…)

The Role of Experience in Science-Based Medicine

Before we had EBM (evidence-based medicine) we had another kind of EBM: experience-based medicine. Mark Crislip has said that the three most dangerous words in medicine are “In my experience.” I agree wholeheartedly. On the other hand, it would be a mistake to discount experience entirely. Dynamite is dangerous too, but when handled with proper safety precautions it can be very useful in mining, road-building, and other endeavors.

When I was in med school, the professor would say “In my experience, drug A works better than drug B.” and we would take careful notes, follow his lead, and prescribe drug A unquestioningly. That is no longer acceptable. Today we ask for controlled studies that objectively compare drug A to drug B. That doesn’t mean the professor’s observations were entirely useless: experience, like anecdotes, can draw attention to things that are worth evaluating with the scientific method.

We don’t always have the pertinent scientific studies needed to make a clinical decision. When there is no hard evidence, a clinician’s experience may be all we have to go on. Knowing that a patient with disease X got better following treatment Y is a step above having no knowledge at all about X or Y. A small step, but arguably better than no step at all. (more…)
