The Occupational Health Field in the

It is the aim of the Cochrane Collaboration to gather, summarise and disseminate evidence of health care interventions. Recently, the Occupational Health Field has started to do so for occupational health interventions. In this article we would like to describe the organisation and the methods used by the Field. First, the use of research information to improve the quality of occupational health practice is explained. Next, the process and contents of Cochrane Reviews are described. The pros and cons of Cochrane Reviews are listed and what occupational health practitioners can learn from it. There is a great variety of occupational health interventions that requires flexibility in which research design to use. The Occupational Health Field will enhance our understanding of the effectiveness of occupational health interventions in the coming years.
