The Trouble With Placebos
The latest NEJM features a big story about a small trial, with only 39 patients in the end, on the potential for placebos to relieve patients’ experience of symptoms. This follows other recent reports on the subjective effectiveness of pseudo-pharmacology.
My point for today is that placebos are problematic in health care with few exceptions. First, in clinical trials, patients sometimes agree to take what might be a placebo so that researchers can measure effects of a drug, by comparison. A second instance is, possibly, when doctors treat children. Even then, I’m not sure it’s wise to “train” kids to take a pill and expect to feel better.
The relationship of an adult patient with a physician involves, or should involve, trust and mutual respect. A person cannot possibly give informed consent for a treatment he or she doesn’t know about. So if the doctor’s giving a placebo to the patient, and making the decision for the patient because it might help, that diminishes the patient’s autonomy, or self-determination. In simpler terms, it’s condescending.
You might consider the hypothesis that there’s nothing wrong with something if it makes you, or someone else, feel better. But that’s kind of like saying the ends justify the means.
A placebo is, by definition, manipulative. I wouldn’t want any doctor to treat me that way.
