The Cochrane Collaboration is an international non-profit organisation that aims to produce high quality systematic reviews of the effectiveness of health interventions. This work is conducted by 51 Review Groups that span a range of topics (e.g. pregnancy and childbirth, HIV/AIDS). The role of Fields within the Collaboration has been to actively engage relevant stakeholders internationally to improve the quality and relevance of reviews. Since the inception in 1996 of the Cochrane Public Health and Health Promotion Field, the Cochrane Collaboration has begun to embrace reviews related to public health and health promotion and is adapting to the changing needs of end-users. The introduction of a Cochrane health promotion and public health review group will help ensure that reviews will be oriented towards building evidence for equity and reducing inequalities and best meet the needs of decision-makers, practitioners and consumers. Our role as a Field has led to us working with a range of partners including reviewers, researchers, practitioners and consumers. Knowledge synthesis, translation and exchange (KST&E) has emerged as an issue in need of further exploration for practice to influence decision-makers and for policy to influence practitioners. 2007 will be an exciting year for evidence-informed Health Promotion and Public Health (HPPH) both within the Cochrane Collaboration and for our partners in policy, practice and research.
