Description and uses of the Delphi method in health sciences research

Abstract

This manuscript deals with an overview of the Delphi technique, from its origin to the stages that constitute the premise to achieve its goal: to reach a consensus among experts. The dynamics of the technique focus on a complex problem, hence resulting in a series of questions that will guide the coordinating group, analyzing and checking the flowing information between the expert group and the coordinating group. Within this process arises timely feedback, an important element in achieving a level of agreement among experts. The technique is useful for research in the area of the health sciences, one of the strengths of this technique is not requiring the presence of the experts, and the dynamics of information management is handled through postal mail or Internet. Experts in the field of health sciences are often professionals with full and complex agendas, but through the use of communication technologies it is possible to have them contribute their judgments and opinions in an efficient manner, making it possible to complete this type of research projects.
