I’ve just uploaded the final text of Big Data: Destroyer of Informed Consent which is due to appear Real Soon Now in a special joint issue of the Yale Journal of Health Policy, Law, and Ethics and the Yale Journal of Law and Technology. This pre-publication version has everything the final version will have except the correct page numbers. Here’s the abstract:
The ‘Revised Common Rule’ took effect on January 21, 2019, marking the first change since 2005 to the federal regulation that governs human subjects research conducted with federal support or in federally supported institutions. The Common Rule had required informed consent before researchers could collect and use identifiable personal health information. While informed consent is far from perfect, it is and was the gold standard for data collection and use policies; the standard in the old Common Rule served an important function as the exemplar for data collection in other contexts.
Unfortunately, true informed consent seems incompatible with modern analytics and ‘Big Data’. Modern analytics hold out the promise of finding unexpected correlations in data; it follows that neither the researcher nor the subject may know what the data collected will be used to discover. In such cases, traditional informed consent in which the researcher fully and carefully explains study goals to subjects is inherently impossible. In response, the Revised Common Rule introduces a new, and less onerous, form of “broad consent” in which human subjects agree to as varied forms of data use and re-use as researchers’ lawyers can squeeze into a consent form. Broad consent paves the way for using identifiable personal health information in modern analytics. But these gains for users of modern analytics come with side-effects, not least a substantial lowering of the aspirational ceiling for other types of information collection, such as in commercial genomic testing.
Continuing improvements in data science also cause a related problem, in that data thought by experimenters to have been de-identified (and thus subject to more relaxed rules about use and re-use) sometimes proves to be re-identifiable after all. The Revised Common Rule fails to take due account of real re-identification risks, especially when DNA is collected. In particular, the Revised Common Rule contemplates storage and re-use of so-called de-identified biospecimens even though these contain DNA that might be re-identifiable with current or foreseeable technology.
Defenders of these aspects of the Revised Common Rule argue that ‘data saves lives.’ But even if that claim is as applicable as its proponents assert, the effects of the Revised Common Rule will not be limited to publicly funded health sciences, and its effects will be harmful elsewhere.
An earlier version, presented at the Yale symposium which the conference volume memorializes, engendered significant controversy — the polite form of howls of rage in a few cases — from medical professionals looking forward to working with Big Data. Since even the longer final version is shorter, and if only for that reason clearer, than much of what I write I wouldn’t be surprised if the final version causes some fuss too.
The enticing ad ran on the bottom right of page A9 of today’s New York Times.
