The ideology of evidence-base medicine (EBM) has dramatically altered the way we think, conceptualize, philosophize and practice medicine. One of its major pillars is the appraisal and classification of evidence. Although important and beneficial, this process currently lacks detail and is in need of reform. In particular, it largely focuses on three key dimensions (design, [type I] alpha error and beta [type II] error) to grade the quality of evidence and often omits other crucial aspects of evidence such as biological (...) plausibility, reproducibility, generalizability, temporality, consistency and coherence. It also over-values the randomized trial and meta-analytical techniques, discounts the biasing effect of single centre execution and gives insufficient weight to large and detailed observational studies. Unless these aspects are progressively included into systems for grading, evaluating and classifying evidence and duly empirically assessed (according to the EBM paradigm), the EBM process and movement will remain open to criticism of being more evidence-biased than evidence-based.

This is a comprehensive and practical guide to the ethical issues raised by different kinds of medical research, and is the first such book to be written with the needs of the researcher in mind. Clearly structured and written in a plain and accessible style, the book covers every significant ethical issue likely to be faced by researchers and research ethics committees. The author outlines and clarifies official guidelines, gives practical advice on how to adhere to these, and suggests procedures (...) in areas where official recommendations are vague or absent. This invaluable handbook will help researchers identify and address the ethical issues at an early stage in the design of their studies, to avoid unnecessary delay and to safeguard the wellbeing of patients and healthy volunteers. It will also be extremely useful to members of research ethics committees. (shrink)

This is the first in a series of five papers on the role, remit and function of research ethics committees which are intended to provide for REC members a broad understanding of the most important issues in research ethics and governance. The first considers the rationale for having ethics review by committee at all; seeking to explain why ethics committees, as we currently have them, are so important to the wider system of governing research.

Recent policy in relation to clinical research proposals in the UK has distinguished between two types of review: scientific and ethical. This distinction has been formally enshrined in the recent changes to research ethics committee structure and operating procedures, introduced as the UK response to the EU Directive on clinical trials. Recent reviews and recommendations have confirmed the place of the distinction and the separate review processes. However, serious reservations can be mounted about the science/ethics distinction and the policy of (...) separate review that has been built upon it. We argue here that, first, the science/ethics distinction is incoherent, and, second, that RECs should not only be permitted to consider a study’s science, but that they have anobligation do so.
