One of the challenges of Medicine is allowing for change. Doctors get trained in ways later discredited. I recall in medical school being told the majority of what we would learn will be either wrong or irrelevant by the time we were physicians – but nobody knows which parts.
Putting down old beliefs and approaches is not as easy as it sounds. Few doctors change the way they practice readily – somewhat from prudence, as this week’s news may be discredited soon afterwards.** If one is interested in “Truth” and patient care, it does mean biting the bullet and admitting your methods are outdated or just plain wrong.
Take for example the long time time honored once upon a time standard of care of blood letting. As Medicine advanced, blood letting was discarded. However, it only left after a long drawn out fight by those who swore it was useful.
Another example is the treatment of insomnia. When I was in training, insomnia was merely a symptom of something else; treat the disorder and the insomnia would dissipate. Sleeping pills were never indicated for more than two weeks. All of this is now wrong; I have to watch myself and my approach when chronic insomnia cases come through the office door.
On the flip side. I am wary to recommend treatments for which there is no great evidence to support it. I realize the placebo effect is vast; if a patient eagerly wants to try – like acupuncture – it will likely work. Yet, is this year’s “scoff” next year’s “truth” and will become standard of care? How much of what I promote today will be someday replaced or even discredited?
I continually try to keep up with the medical news, particularly in my field of psychiatry, which grows by leaps and bounds. I have to simultaneously be wary of ‘news flashes’, yet ready to change how I practice if evidence-based medicine tells me to do so.
It keeps me on my toes.
**Vitamin E has gone from ‘good’ to bad’ several times. Right now it is ‘bad’. I sense Vitamin D, now on the ‘good list’ will drop off likewise.

Right now I’m on my way to the googles to see what Blood Letting is. And you’re telling me that I’m supposed to stop my once a day 400iu of vitamin E? Oh lord.

“The latest news” suggests people who tend to bleed or have ‘blood thinners’, or People who are eating properly don’t need Vitamin E supplements.
Taking megadoses of certain types of Vitamin E (for there are 8 types) are correlated to an increased risk of prostate cancer.
So, in general, men who are eating OK shouldn’t take extra Vitamin E, unless their doctors says you need the supplementation.

So, do you think the “placebo effect” or your example of a much desired procedure such as acupuncture proving effective possibly because of the desire for it, indicate that the patient’s mental state (belief in a treatment) can actually control at least part of the outcome?

Trade with me! I’ve been in the I.T. field for near 20 years now and the changes have been nothing short of astonishing.
I recall the days of Btreive database engines and now we use innodb etc.

I think this is true of medicine because it is not an exact science and it depends on genes and peoples habits, etc…
Some people go through life with nothing to worry about and die in advanced old age in their sleep, lucky them. While others are constantly in pain or suffer from lots of weird diseases. My doctor says it depends on your genes, good genes and you get a good life. Say thank you to your parents.

Happily, most illnesses have a 50% genetic contribution, the rest is environmental. Thus, you may inherit the ‘family gun’, but you have a lot of choice whether to obtain the bullets….

Great post. Have you encountered a book called The Structure of Scientific Revolutions by Thomas Kuhn? It describes some of the processes involved in changing major scientific ideas. I’m sure many similar things happen around changing ideas in medicine.

Working in programming / software testing is just as frenetic. There is always a new language to learn, a new style of ‘doing things’ or new software/hardware with new requirements.

I didn’t get the “vitamin E is bad” memo. Since I don’t take extra vitamin E I’m not going to worry about it. And I don’t think my prostate is in imminent danger, either.

Interesting that you brought up the subject of bloodletting. I have used that example when referring to the usefullness of PSA scores to indicate prostate cancer. Someday in the future our society maylook upon using high PSA scores as totally useless in indicating prostate cancer. The medical establishment like any other authority, is always slow to admit mistakes. How long did it take the Catholic Church to apologize to Galiello?

The difference hopefully is Medicine is about science and truth: ever changing and therefore not mistaken so much as zoning in on better truths.
