Science, Reason, Ethics, and Modern Medicine, Part 3: Implausible Claims and Formal Ethics Statements
The Ethics of Implausible Medical Claims (IMC)
In Part 2 of this series* we learned from David Katz, MD, a key member of the Yale School of Medicine’s “integrative medicine” program, that he had been “pushed toward integrative medicine by the needs of [his] patients.” We also learned that Dr. Katz’s rationale for this decision justifies a wide range of quackery—both in principle and in fact. I had previously alluded to arguments like those of Dr. Katz in a comment on SBM several months ago:
…we must be true to medical ethics, no matter what else we do. If that means losing a few patients, so be it. Patients are free agents, and we can only do so much to influence them. To the extent that we don’t do that as well as we might (which is obviously true in some cases), we might do better. But our ethical obligation is to science and truth; it is not, as many modern physicians would have it and as much as we may lament sometimes losing patients to woo, to seducing patients to stick with us no matter what, if the “what” includes engaging in a charade about “integration” or “complementary therapies”…
Realizing that some might argue that physicians’ obligations to patients ought to trump their obligations to “science and truth,” I later revised that statement:
Several weeks ago I argued here that a physician’s primary ethical obligation is to science and truth. In retrospect I probably should have put it a slightly different way: a physician’s primary ethical obligation is the same as everyone else’s. It is to honesty and integrity. For physicians, however, that means being true to real medical knowledge, among other things, and real medical knowledge comes from science.
In spite of that revision, two readers whose opinions I respect challenged my assertion. Dr. Peter Moran’s worthy efforts to educate patients about the realities of “alternative” cancer treatments are considerable. Here on SBM he has repeatedly challenged us to explain how, when confronted with testimonials of “alternative” cures, we ought to respond without using “a high-handed, ‘we know best’ stance” and thus “appear to want to distance [ourselves] from the intimate concerns of [our] patients.” I was thinking mainly of him when I wrote the revision above, because on this key topic—how to respond ethically, but with compassion, to patients who want to believe in implausible treatments—I’ve come to think of Dr. Moran as the “conscience” of Science-Based Medicine. Those with cancer, he has reminded us, “are folk very like you and me who are simply grasping at any straw that might save or prolong their lives.” His take on why IMCs are appealing to those with less ominous problems is well-developed and agrees with my own, mostly. We part ways, however, when he concludes (also here and here) that ethical physicians might have good reasons—unlike Dr. Katz’s—to entertain benign, if implausible treatments:
