Most people are familiar with the basics of the placebo effect: an ailing
patient is given some kind of fake medical treatment (a sugar pill, an
injection of a simple saline solution, etc.) and told that it is a drug that
will treat what ails them. Despite the fact that whatever they just took has no
pharmacological effects whatsoever, the patient (at least temporarily) reports
a significant improvement in their symptoms.
This is a fascinating illustration of how complex the
interactions between the mind and body can be. Of course, it also makes testing
new drugs or therapies more difficult: if a new treatment appears to be
effective, how can we tell it’s not simply a result of the placebo effect? Modern
clinical trials work around this problem by giving half of the test subjects
the real treatment, and the other half a fake treatment, without telling them
what they’re getting. If the real treatment is more effective than the placebo,
the people conducting the study know that the drug is actually causing the
desired effect.
The placebo (Latin for “I shall please”) effect has been
known for centuries, well before the advent of modern medicine. It was first
reported in the 1700s when doctors discovered that patients’ symptoms could be
somewhat relieved simply by telling them that they were taking an effective
medicine. Until very recently, the placebo effect has been viewed as little
more than a curiosity or annoyance.
Over the last 10 years, however, there has been a renewed
interest in placebos as a treatment in their own right. New studies have shown
that placebo effects can produce objectively-observable changes in a patient’s
body. For example, a fake painkiller triggers the brain to produce its own
natural painkillers. In one study, patients suffering chronic pain were given
inert treatments, while being told it was morphine. Predictably, they reported
some improvement in their pain. However, some of those patients were, without
their knowledge, given a drug which temporarily blocks the effects of morphine.
The result? The placebo was far less effective. This illustrated the fact that
there’s far more going on with the placebo effect than we once thought.
An article
in the Boston Globe raises a very thorny question: if placebos can, in some
cases, be almost as effective as real medicine, without the side effects or
financial cost, shouldn’t they be considered as a valid treatment option? Now,
obviously, there are plenty of things we know placebos can’t do: a transfusion
of strawberry Kool-Aid instead of blood isn’t going to save a patient from
bleeding to death, and a fake heart transplant isn’t going to save a patient’s
life. Placebos seem to work best when treating symptoms, rather than the
underlying causes of disease. Then again, some medications that almost all of
us have taken at some point in our lives (aspirin, cold medicine, etc.) do
nothing to treat the underlying causes of a disease, but they do alleviate the
symptoms.
So, all of this seems to indicate that doctors should start
adding placebos to their arsenal of treatment options, right? Well, maybe. I
wouldn’t be writing about this if there weren’t some serious legal concerns.
First, and perhaps most obviously, placebos only seem to
work if the patient believes they’re getting real treatment. One of the
cornerstones of modern medical ethics is “informed consent,” meaning that,
before treatment is given, the patient (1) has to consent to the treatment, and
(2) has to have all the information necessary to make a reasonably-informed
decision on the matter. You can probably see where this is going. Placebos seem
to work best (if at all) when the patient believes they’re getting an actual
drug. This means that delivering an effective placebo is impossible if informed
consent is a requirement.
Furthermore, even if placebos do have some legitimate
medical applications, they’ll certainly be quite limited, probably to treating
mild pain, depression, and other somewhat subjective (though no less real)
ailments. However, the fact that these treatments are basically free might make
it very tempting for penny-pinching doctors and health insurers (both public
and private) to include them in their treatments, without a patient’s knowledge
or consent.
As the law currently stands, this would almost certainly
constitute fraud. Fraud, after all, involves lying to someone to induce them
into buying a product or service, and thereby causing them harm. It’s easy to
see how this could happen, especially if a provider gets a little over-zealous,
or overestimates what can be accomplished with a placebo.
Additionally, if a doctor decides that a symptom can be
alleviated just as effectively with a placebo as with real medicine, but turns
out to be wrong, thereby injuring a patient, he or she would almost certainly
be liable for medical malpractice. After all, doctors are expected to exercise
the skill and knowledge that their years of medical training have given them.
Failure to do so, when it results in an injury to the patient, is medical
malpractice and grounds for a lawsuit.
In addition to fraud, prescribing a placebo in place of real
medicine, in the hopes that it will produce the same effect at a fraction of
the price, would almost certainly constitute malpractice if it could be shown
(which would be likely in many cases) that the patient would have gotten better
results with real medicine (and if the medicine was approved by the FDA, this
has already necessarily been proven).
Obviously, before doctors could even consider this as a
valid treatment option, much more medical research would be needed. On top of
that, the ethical and legal questions would have to be resolved. Of course, our
legal system works in such a way that tough legal questions are often answered
with test cases. It’s not exactly clear how many doctors would be willing to
put their careers and reputations on the line to test the legality of these
types of treatments. Time will tell.
