Policy makers and continuing educators often face difficult decisions about which educational and quality assurance interventions to provide. Where possible, such decisions are best informed by rigorous evidence, such as that provided by systematic reviews. The Cochrane Collaboration is an international organization that aims to help people make well-informed decisions about health care by preparing, maintaining, and ensuring the accessibility of systematic reviews of the benefits and risks of health care interventions. International collaborative review groups prepare Cochrane reviews for publication in The Cochrane Library, a collection of databases available on CD-ROM and the World Wide Web and updated quarterly. The Cochrane Effective Practice and Organization of Care Group (EPOC) aims to prepare and maintain systematic reviews of professional, financial, organizational, and regulatory interventions that are designed to improve professional practice and the delivery of effective health services. EPOC has 17 reviews and 20 protocols published in Issue 3, 2000, of the Cochrane Library, with further protocols in development. We also have undertaken an overview of previously published systematic reviews of professional behavior change strategies. Our specialized register contains details of over 1,800 studies that fall within the group's scope. Systematic reviews provide a valuable source of information for policy makers and educators involved in planning continuing education and quality assurance initiatives and organizational change. EPOC will attempt to keep the Journal of Continuing Education in the Health Professions informed on an ongoing basis about new systematic reviews that it produces in the area of continuing medical education and quality assurance.
