Care pathways are complex interventions in complex systems: New European Pathway Association framework

Care pathway implementation is characterised by a dual complexity. A care pathway itself represents a complex intervention with multiple interacting and interdependent intervention components and outcomes. The organisations in which care pathways are being implemented represent complex systems that need to be directed at change through an in-depth understanding of their external and internal context in which they are functioning in. This study sets out a new evidence-based and pragmatic framework that unpacks how intervention mechanisms, intervention fidelity and care context are converge and represent interacting processes that determine success or failure of the care pathway. We recommend researchers looking to increase the effectiveness of care pathway implementation and accelerate improvement of desired outcomes to adopt this framework from inception to implementation of the intervention.
