Alternative Revenue Stream for Private Practice Physicians – Research Investigator

Clinical research is the only way [for a physician in the managed care era] to make a boat payment, quips David Stark, M.D.

With increasing frequency, pharmaceutical and medical device companies are turning to physicians in private practice, rather than academic medical centers, to serve as investigators overseeing the 60,000-odd clinical trials each year, between 80 and 90% of which are funded by industry as opposed to, say, NIH. Academic medical centers are losing the “business,” having fallen from 63% to 26% as the site for clinical research between 1994 and 2004. While it might be argued that trials in the private practice setting produce superior results because they occur under circumstances that more closely resemble how the drug or device will actually be used if approved by the FDA, there are significant risks attendant to this phenomenon that have received too little attention.

The ultimate question is whether physicians can compartmentalize the competing incentives that exist in advising patients about whether to pursue conventional therapy or participate in a clinical trial. This is especially true if the physician is being handsomely compensated for each patient she recruits into a trial, and is exacerbated when the physician also has other financial relationships with the trial sponsor (the drug or device company) for, say, speaking and consulting gigs. Clinical Research in the Private Office Setting — Ethical Issues The recruitment process for clinical trials is the longest and most costly part of the process - prospective participants have to undergo testing to see if they qualify for the study, and federal law requires that they receive significant amounts of information and have ample opportunity to have their questions answered pre-enrollment. A per capita payment contingent upon successful enrollment of the patient will tempt a physician to fudge on this process and enroll unqualified subjects. This not only may put them at risk because they are too sick, but also skew the research results because they’re not sick enough. Bonuses for meeting enrollment goals only make it worse.

Without impugning physician integrity, how realistic it is for physicians to serve in the dual capacity of treating physician and researcher? Studies have repeatedly confirmed “therapeutic misconception” whereby study participants believe, no matter how clearly told to the contrary, that they are “patients” receiving treatment, rather than “subjects” of research who may be receiving a placebo or an experimental drug. This phenomenon is certainly exacerbated when the patient’s treating physician is doubling as the investigator of the clinical trial. Most patients continue to believe that their own personal physician would be driven solely by their best interests. Ironically, some people have more faith in an experimental intervention when they learn that the investigator has a “piece of the action.”

Obviously, significant policy and legal questions arise from this practice, and a more holistic approach to the question of the best way to encourage clinical trials while safeguarding the interests of trial subjects is beyond what I can attempt here. But one possible approach could be drawn from informed consent law — whether statutory or common law, which should require physician disclosure of conflicts of interest to patients. Imagine the beginning of a conversation between doctor and patient/potential research subject:

Doctor: “Just so you know, if you agree to participate in this clinical trial, I get paid $1000 by the manufacturer of the product being tested, but if you don’t, and you just want regular treatment, I’ll only get paid $60 by your insurance company. But, in fairness, that’s because a clinical trial is a lot more work for me….”

But to be honest, I don’t really believe in this solution either. Most recipients of this information either don’t understand it, or have no idea what to do with it, or both. Some fear that too much confusing information might kill trials altogether, which would be a terrible outcome. And there are certainly reasons to fear that such trials are becoming harder to run, to the point where they’re not worth the money. Ultimately, I guess, I want to control how physicians get paid to serve as investigators — the Goldilocks Solution — not too much, and not too little. I want them to be paid just right, so that they are willing to conduct clinical trials, but aren’t tempted to act other than in the patient’s best interest. Of course, what is just right and how to enforce it poses its own problems.

Drug Study Fails to Mention Risk of Death to Test Subjects

Danse Macabre, XLVII, The Blind Man. Hans Holbein the Younger (1497 or 1498 to 1543)

As reported recently in the Boston Globe, a federal probe found that heart attack survivors enrolled in a clinical trial conducted in over 120 sites nationally had not been adequately informed of the safety risks of the study, including the risk of death.

The process under study, chelation, involves “periodic infusions of a drug– in this case, disodium EDTA.” The infusions are being tested in conjunction with the ingestion of high doses of  vitamins and minerals. However, according to the federal probe, “in 2008 FDA removed disodium EDTA from the FDA’s approved list and withdrew of approval of new drug applications for disodium EDTA.” Test subjects were not informed that disdodium EDTA “is no longer FDA approved for any use and has been removed from the market because of safety concerns.”

Funded by the National Heart, Lung and Blood Institute and the National Center for Complementary and Alternative Medicine, the study has over 1,500 subjects. Though researchers suspended enrollment last August due to the investigation, federal officials allowed the study to continue pending further findings of the probe, a decision that has been highly criticized.

In addition to the deficiencies regarding the  informed consent of study participants, the Boston Globe reported that the investigation found that several co-investigators involved in the study had been disciplined for “substandard practices” or had been involved in insurance fraud. Three were convicted felons. Federal officials explained that they found the substandard practices and convictions of the principal investigators “concerning” but not a reason to “automatically preclude an investigator from participating in research.”

The U.S. Office of Human Research Protections detailed the findings of the investigation and required corrective actions in a letter to the three medical institutions heading the study. In response to the investigation’s findings, the study modified the consent form to recognize death as a “rare complication of the EDTA [chelation] infusions.” The Office of Human Research Protections has also requested further modification of the form to disclose that disodium EDTA had been removed from the market.

Despite the change in consent form, questions remain about the acceptability of the risks posed by the study. As the Globe reports, critics of the study, including the head of bioethics at the University of Pennsylvania, Arthur Caplan, have charged that the risks posed by the study are unethical. The complaint against the study filed with the Office of Human Research Protections noted that since “the mid-1970’s court documents and newspapers have reported at least 30 deaths associated with intravenous EDTA.”

The probe is the lastest in a string of major investigations of clinical trials, including the continuing investigation into payments by device maker Medtronic to Dr. Timothy Kulko (who is accused of falsifying author names and  study results), and the Synthes indictment for allegations that its subsidiary, Norian, conspired to conduct unauthorized clinical trials that placed subjects at risk of death without properly informing them of the risks. In the Synthes/Norian matter, three patients are believed to have died as a result of the use of the companies’ bone cement products.
