A change in the way health care and research is defined could translate into big savings for institutions, according to bioethicists from Johns Hopkins whose study will be published in The Hastings Center Report. The researchers suggest the nation's current ethical paradigm is outdated, and calls for those in the health care field to move toward a learning health care system. UTMB’s Dr. Howard Brody said the current model separates the health care system into research, practice and a gray zone. The gray zone, Brody said, is activity that is not designed to benefit the patient directly, but is supposed to improve quality of care in the system.
