Another misleading case of ethics dumping - compensation for research injury


Another case in the book on Ethics dumping concerns the issue of compensation for research injury, written by Cong Yali: Legal and Ethical Issues of Justice: Global and Local Perspectives on Compensation for Serious Adverse Events in Clinical Trials

The case is about a phase III trial of a drug developed by the pharmaceutical company Bayer to prevent blood clots in patients after knee surgery. The clinical trial compared this drug administered once a day as a tablet against another standard anti blood clot prevention method given by injection. Two weeks after surgery the patients underwent a clinical examination and a test for blood clot formation by angiography. One patient experienced a reaction shortly after completion of the angiography: low blood pressure, chest tightness, cough and sweating. The likely diagnosis was hypovolemic shock, and the patient was treated with a saline solution and dopamine. After about one hour blood pressure was stabilized and after an additional 90 minutes the patient had recovered. The patient was discharged, but returned the next day because she was not feeling well, and was admitted to the hospital again. The doctors suspected possible pulmonary embolism as a result of a blood clot formation. They did a comprehensive examination and ordered bed rest and anticoagulant therapy. After two weeks the patient was discharged but pulmonary embolism had been excluded. Because of the necessary bed rest there was a worry that normal rehabilitation of the knee after the operation would be hampered, resulting in possible loss of function. The event was reported as a serious adverse event.

The patient wanted compensation for this adverse event. Typically, in order to be awarded compensation for research injury the patient needs to show that the cause of the adverse event was a procedure done for research purposes and that there is a compensable injury. Since the patient was discharged from the hospital, and the company had already paid the hospital bill, the patient would have to demonstrate that there is a persistent loss of function or other injury after discharge. The patient, however, refused to undergo an examination by a physician to provide evidence of such persistent injury. The company therefore naturally rejected the claim, since there was no injury to be compensated.

Instead of bringing a suit against the company based on the presence of persistent injury, the plaintiff brought a breach of contract case against Bayer. Basically, the plaintiff claimed that by signing the informed consent form to take part in the trial sponsored by Bayer, the plaintiff had entered into a contract with Bayer. This contract specified that the insurance is available for research injury. Since anaphylactic shock after angiography is mentioned in the informed consent form as a possible risk of angiography, this event should be covered by the insurance contract, and consequently by the contract between the plaintiff and Bayer. According to the insurance policy the maximum compensation amount is 500.000 Euros for each patient. This would cover all possible injuries, and it would therefore be reasonable that the plaintiff was awarded a portion of this amount for her injury. 150.000 Euros was estimated as a reasonable proportion given the seriousness of the adverse event. The court decided to award the plaintiff an amount of 50.000 Euros, the plaintiff appealed this decision. The appeal was denied, and the plaintiff was awarded 50.000 which was paid by Bayer.
The author of this chapter identifies three specific ethical issues raised by this case. First there is the cost of litigation, second is the variations in compensation between countries, and third is the inequality between the sponsor and the research subject in terms of access to resources. The second issue is to a large degree a result of differences in national laws, and would be outside the scope of most issues related to ethics. The first and the third are essentially the same: Proving causality between research participation and injury is difficult and can result in costly court procedures. This is indeed a challenge that needs more attention in research ethics. It may be possible to suggest procedures that can ease the burdens of proving causation in cases of presumed research injury. The problem is that the case that is presented in the chapter does not illustrate this problem at all, because it was not tried as a research injury case, but as a breach of contract case.

First, there is the denial of the patient to undergo an examination to provide evidence of injury. This is a necessary condition for any case of research injury compensation. Second, it is not even clear that there is a probable causal relationship between the research procedures and the adverse event. There is no disagreement that it was not caused by the investigational drug. It could either be caused by the angiography if it was a reaction to that procedure, or it could be caused by the surgery if it was a case of pulmonary embolism as a result of the blood clot. The clinical record leaves both options open. If caused by the surgery it was definitely not caused by a research procedure. If caused by the angiography it is less clear. On the one hand the procedure could be seen as part of the research to establish one of the endpoints of the study (deep vein thrombosis) or it could be seen as clinical follow to detect thrombosis and treat it if it is identified. In that case the procedure is actually of benefit to the patient even though there is an extremely small risk of shock.  Based on the questionable causal relationship and the fact that there was no evidence of injury it is likely that any court in any of the other countries where the trial also recruited patients would have awarded any research injury compensation.

The patient, however, decided to try this case as a breach of contract case. The court agreed that it could be brought forward on that basis and did award 50.000 Euros to the plaintiff on that basis. It seems that the court argued that any adverse event mentioned in the informed consent form automatically gives rise to a compensation claim, in proportion to its severity based on a maximum award of 500.000. This would be independent of whether the event led to any persistent injury. The experience of the event itself, whether it was caused by the research procedures or not, should be compensated.

It may very well be that this is an appropriate legal analysis of the case based on Chinese law. From an international perspective it is highly unusual and would probably be rejected by the legal systems in many countries. The case description, however, gives the reader no reason to believe that this is an accepted legal analysis in China. It was reached by a lower court, there is no reference to other court decisions, and there is no legal analysis of the reasoning of the court by an expert in Chinese law. Given the uniqueness and extraordinary nature of the decision by the court, one would have expected that the chapter contained some legal analysis. Instead it is basically an account of the reasoning of this particular court supplemented with information from the plaintiff’s family.

By now it is generally accepted that if a person is injured as a result of research participation they should be compensated for that injury. The difficult, unresolved issues are about one should understand that requirement. One issue concerns the requirement that there is a causal relationship between the research participation and the injury. Clearly, not all bad things that happen to people who are in research should be compensated. People may die in traffic accidents, they may suffer other injuries, or they may get unrelated diseases. In clinical research, the underlying disease or the ordinary treatment for the condition may also cause injury. Only injury that is caused by procedures done for research purposes should be compensated. The challenge is often how to identify what is caused by the research and what is caused by something else. Another issue concerns how much a person should be compensated. There is no disagreement that direct expenses related to treating the injury should be compensated, and expenses related to long-term effects of the injury. This could be economic loss because of need for rehabilitation or diminished ability to work, resulting in salary loss or reduction. Provisions for any additional compensation, such as for the fact that one has been injured, for the emotional effects of injury, or for the restriction in activities that one can carry out, but which do not result in any economic loss, vary between countries. It would have been useful to have some discussion of these issues in this chapter and in this book. Instead we get a misleading description of what appears to be a unique case, without any attempt at legal analysis by experts in Chinese Law. And it is difficult to see that this is a typical case of “ethics dumping”, and should form any basis for recommendations about funding decisions by the European Commission.

The court's decision is given here (in Chinese).
