The process of research is often lengthy and can be extremely arduous. It may take many years to proceed from the initial development of an idea through to the comparison of the new modalities against a current gold-standard practice. Each step along the way involves rigorous scientific review, where protocols are scrutinized by multiple scientists not only in the specific field at hand but related fields as well. In addition to scientific review, most countries require a further review by a (...) panel that will specifically address the ethics of the proposed research. In Canada, those panels are referred to as Research Ethics Boards (REB), with the United States counterparts known as Institutional Review Boards (IRB). (shrink)
