Research ethics

Informed consent and therapeutic misconception

The conventional wisdom about research participants is that 'true informed consent is impossible' and that 'research participants misunderstand the purpose and the risks and benefits of research because they are so desperate.' But do we really need to be that pessimistic? Perhaps these beliefs also reflect our failure to accurately understand the participants' perspective. For example, in a series of studies, we have shown that when a participant seems to not understand the purpose of research, it is most likely due to their not interpreting (in the way we intend them) the questions we are using to measure their understanding. Kevin Weinfurt has reminded us of this common fallacy among researchers in a recent article. This research draws on considerations of pragmatics.

Part of this confusion is also likely due to the widespread belief that, since the primary purpose of research is societal or scientific, there is something wrong with participants in clinical trials being motivated by a desire for therapeutic benefit. But this confuses motivation with understanding. (People are motivated by money in buying a lottery ticket but they aren't confused about what it is--a gamble). In fact, this confusion keeps us from providing the kind of information that would be useful to people who are in fact motivated by desire for benefit. Several of my studies are designed to probe this issue. For example, many early phase research informed consent forms use the phrase "it is not guaranteed that you will benefit" as though benefit is so likely that the question really is about whether it is certain or not. Or when available effective treatments are withheld in order to test a new drug, we seldom tell the subjects all that we should about what they are giving up.

Pragmatic RCTs and Comparative Effectiveness Trials

Comparative effectiveness research (CER) compares two or more already-in-use treatments (often FDA approved) to determine which is the most effective. Although most of this research is observational ('big data' research of medical records), CER can also involve head-to-head randomized clinical trials (RCTs). Drug companies have little incentive to conduct head-to-head trials. But such studies could be invaluable in keeping down overall health care costs.

Since such studies involve treatments that are already used in clinical practice (i.e., they do not involve novel or experimental treatments with a lot of unknowns), some have argued that perhaps such studies add no additional risk beyond the risks of usual treatment. Some have argued, based on this line of reasoning, that some CER studies do not even need informed consent. I have doubts about this line of reasoning.

My work focuses on how to analyze research risks in CER RCTs, whether informed consent can be ethically waived in some CER RCTs, and when traditional written informed consent may be not only unnecessary but less than ideal.

IRB Reform

The IRB system wastes money and resources on oversight of extremely low risk, non-controversial research that do not need it. Those resources could better be used to improve oversight of more risky and controversial studies.
