Ethical and Policy Issues in Cluster Randomized Trials

doctor in hospital room

The gap between medical evidence and medical practice is one of the most important challenges for the health of Canadians. The cluster randomized trial (CRT) is the major methodological tool in use in the development of new interventions to bridge the gap between evidence and practice. This project brings together clinical trialists, biostatisticians, and philosophers to address ethical and policy obstacles to the conduct of CRTs. The project uses an innovative “mixed methods” approach to document current practice and analyze ethical issues. A major outcome is the development of international ethics guidelines for CRTs.
