In the lion's den? Experiences of interaction with research ethics committees.

Research ethics review is an important process, designed to protect participants in medical research. However, it is increasingly criticised for failing to meet its aims.

They highlight some problems faced by reviewers and researchers and propose a two-stage ethical review process that would alert researchers to the committee's concerns and allow them to give a more considered response.
