Conflict of interest in medicine

Recent news reports described an "ethical lapse" by a prominent New York City cancer specialist. In research published in prominent medical journals, he failed to disclose millions of dollars in payments he had received from drug and healthcare companies that were related to his research. Why is this such a big deal? Disclosing any potential conflict of interest is considered essential for the integrity of medical research. The thinking is that other researchers, doctors, patients, regulators, investors - everyone! - has a right to know if the researcher might be biased, and that measures have been taken to minimize the possibility of bias.

Is it an advertisement or research?

One way to think about the importance of full disclosure regarding medical research is to ask: is the information I'm reading or hearing about coming from a paid spokesperson? If so, it may be the equivalent of an advertisement. Or, is it from a researcher without a financial stake in the results? The answer matters. While the information may be valid either way, the way it's delivered, how alternative explanations for the results are considered, and the skepticism (or enthusiasm) surrounding the findings can vary a lot depending on whether the source has a vested interest in a study's results.

One of my favorite examples of how bias can affect how medical information is delivered is the way pain relievers (such as ibuprofen or naproxen) are described in ads. There are more than 20 of them available, and for most conditions their effectiveness is about the same. And that's exactly how a researcher with no financial ties to the makers of these drugs might describe them: in clinical trials, they are equally effective. But a company's television ad might claim that "nothing's proven stronger for your headaches" than their medication. Factually, both ways of presenting the information are true. But knowing the source of the information and whether it might be biased can make a big difference in how you interpret that information.

Why you should care about conflict of interest in medicine

Medical schools, hospital systems, and other institutions that employ doctors generally require disclosure of outside income. But do their patients want to know? Would it matter to you if your doctor accepted gifts, meals, or cash payments from drug companies?

There's been enough concern about the answers to these questions that the federal government set up a website to post information about payments doctors receive from drug companies, medical device makers, and others. Perhaps you've heard of it. It's called OpenPayments,* a disclosure program mandated by the Sunshine Act that posts these financial relationships online for public viewing. It's been up and running for several years. But the impact of this program is not clear; many of my patients have never heard of it, and most people have never looked up their own doctors on the site.

*In the interest of full disclosure, my name appears in Open Payments: However, it's for consulting with the Institute for Healthcare Improvement, an independent healthcare organization. They provided grants to encourage shared decision making and understanding of treatment options for patients with rheumatoid arthritis. A pharmaceutical company sponsored the program but has no role in promoting any particular medication.

Other ethical issues your doctor might face

Even if your doctor doesn't accept payments from pharmaceutical companies, he or she may have to consider other ethical questions, such as:

• Is it acceptable to own his or her own testing equipment? While it may be more convenient for patients, studies show that when a practice performs (and charges for) its own lab or imaging tests (such as a scanner for osteoporosis screening), more tests tend to be ordered.
• Should he or she meet with representatives from pharmaceutical companies who are promoting their latest drugs? Some physicians get updates regarding new medications from drug reps (along with gifts of minor value, such as pens or lunch), but this may lead to higher rates of prescribing newer, higher priced drugs when older, cheaper options would be just as good.
• Should your doctor attend medical meetings where drug companies sponsor the speaker (complete with dinner in a fancy restaurant)? Again, the information presented may be accurate but biased.
• Is it reasonable for doctors to receive payments to enroll patients in a study sponsored by a drug company? This is a common practice, and it's likely that the financial arrangement is not always disclosed to the patient.

And these are just a few of the many ethical dilemmas that many doctors face.

What do you think?

Many doctors I know are insulted by the suggestion that they "can be bought" by a charismatic drug rep bearing gifts. But a number of studies show these practices work. Large pharmaceutical companies spend millions on doctors to market, educate, and perform clinical trials. They would not invest so much money if it didn't work.

Does any of this concern you? Do you think the case of the NYC doctor is unusual and that most doctors navigate the ethical minefields of modern medicine successfully? Let me know!
