[The professional differentiation in medical practice. A theoretical model of the process of changing]

The structure of the change process on medical professionalization has not being studied enough. The physicians are made aware of the necessity of changing their medical practice in ways that also affect their personal life. A change involves the need to plan, evaluate possibilities and resources with efficacy and outline competencies. The aim is to contribute in the design of educational strategies that promote professional change and an understanding of change, as an evolution; we describe a theoretical-schematic model based on five consecutive ordained scopes: background, intentions, planning and making decisions, carrying out decisions and achieving the goal.
