[Management of risk of errors in health: which representation for a systemic approach?]

The management of the risk of error in Health currently configures as an institutionalized multi/hetero-professional and "complex" activity. This implicates the need to establish rules that codify the modalities of interaction among the actors, as well as rules of communication, which, defining in a clear and univocal way the terminology used, allow the different actors to understand themselves. The representation of these rules implies a systemic and global conceptual approach in which the attention is moved from "the physician's performance" to the "performance in Health": the whole System must be structured and employed in order to pretend towards a continuous improvement of Quality and Safety.
