There is quite a bit of art to the practice of medicine: knowing how to get and to give information to a patient, how to create a sense of worry without creating a feeling of panic, how to use the best available science to help them maintain or return to health. Underlying all of the art is the science: what blood pressure is likely to be harmful in a particular patient? What can I offer to mitigate this harm? This science is developed over years by observation and systematic study. We have a very good idea of what blood pressure levels are optimal to prevent heart attacks in various populations. These data are hard-won. It has taken decades and it continues.
If a researcher were to discover a promising, new blood pressure intervention, they would have a long way to go from bench to bedside. They would have to prove as well as possible that it is safe and effective—and from a science-based medicine perspective, that it is even plausible. If the discovery is a drug that relaxes blood vessels, or a type of exercise, we have good reason to believe it might work and can go on to figuring out if it does work. If the intervention is wearing plaid every day, we have little reason to think this would be effective, and it probably isn’t worth the time and cost of looking into it.
The well-respected journal Cancer has just wasted space in the study of wearing plaid. Well, not really; it’s worse than that. The article is called, “Complementary medicine for fatigue and cortisol variability in breast cancer survivors: A Randomized Controlled Trial.” There is nothing that isn’t wrong with this study, and if it weren’t published in a major journal, it might even be light comedy.
Tragedy wins the day, however, because cancer is a big deal, and I don’t like it when people mess around with cancer.
