Understanding the implementation of complex interventions in health care: the normalization process model.

摘要: Background: The Normalization Process Model is a theoretical model that assists in explaining the processes by which complex interventions become routinely embedded health care practice. It offers framework for process evaluation and also comparative studies of interventions. focuses on factors promote or inhibit routine embedding Methods: A formal theory structure used to define model, its internal causal relations mechanisms. broken down show it consistent adequate generating accurate description, systematic explanation, production rational knowledge claims about workability integration Results: explains normalization reference four demonstrated operationalization (interactional workability, relational integration, skill-set contextual integration). Conclusion: adequate. Repeated calls theoretically sound evaluations randomized controlled trials interventions, policy-makers who call proper understanding implementation processes, emphasize value conceptual tools like Model.
