Hastings Center Report special report on ethical oversight of learning health care systems

The longstanding ethical framework for protecting human volunteers in medical research needs to be replaced because it is outdated and can impede efforts to improve health care quality, assert leaders in bioethics, medicine, and health policy in two companion articles in a Hastings Center Report special report, "Ethical Oversight of Learning Health Care Systems." One of the authors calling for a new approach is the main architect of the current ethical framework.

Seven commentaries in the publication, written by leaders with national responsibility for ethical oversight of medical research and efforts to improve health care quality, find areas of agreement and offer critiques.

In an accompanying editorial, co-guest editors Mildred Z. Solomon, President of The Hastings Center and Ann C. Bonham, Chief Scientific Officer at the American Association of Medical Colleges, wrote that by inviting these commentaries, they aimed to "provoke a national conversation." According to Solomon, "The challenge is to design oversight that adequately protects patients without impeding the kinds of data collection activities we need to improve health care quality, reduce disparities, and bring down our rate of medical errors." (See video of Dr. Solomon on the importance of this debate.)

For nearly four decades, protection of human participants in medical research has been based on the premise that there is a clear line between medical research and medical treatment. But, the two feature articles argue, that distinction has become blurred now that health care systems across the country are beginning to collect data from patients when they come in for treatment or follow-up. The Institute of Medicine has recommended that health care organizations do this kind of research, calling on them to become "learning health care systems."

In particular, the articles challenge the prevailing view that participating in medical research is inherently riskier and provides less benefit than receiving medical care. They point out that more than half of medical treatments lack evidence of effectiveness, putting patients at risk of harm. On the other hand, some kinds of clinical research are no riskier than clinical care and are potentially more beneficial; an example is comparative effectiveness research to find out which of two or more widely used interventions for a particular condition works best for which patients.

"Relying on this faulty research-practice distinction as the criterion that triggers ethical oversight has resulted in two major problems," the authors write. First, it has led to "delays, confusion, and frustrations in the regulatory environment" when institutional review boards, which are responsible for the ethical oversight of research with human subjects, have difficulty distinguishing between research and clinical practice. Second, it has "resulted in a morally questionable public policy in which many patients are either underprotected from clinical practice risks (when exposed to interventions of unproven effectiveness or to risks of medical error) or overprotected from learning activities that are of low risk . . . and that stand to contribute to improving health care safety, effectiveness, and value."
