Abstract: This article explores the application of professional practice models in nursing. Particular reference is made to the magnet hospital model and the concept of shared governance. Key principles from these models are explored in relation to the implementation of a professional practice model in an intensive care environment. Historical, cultural and professional factors that may be seen as barriers to the implementation of this professional practice model are also explored. In conclusion, the article identifies recommendations that may contribute to a successful implementation and duration of a model in practice.
