Aim. The paper presents the development and structure of a generic stroke care simulation model, used in designing of a stroke unit in Sweden. Background and rationale. Designing new health care spaces is a multifaceted process; requiring multi-professional (nurses, other healthcare professionals, building planners and architects) involvement. To secure that the patients’ interest are in focus the different stakeholders need to analyze and develop a common understanding of the care processes that are to take place in the new space. Modeling and simulation is one significant method, making it possible to depict the dynamic structure of the system and experiment with the model, asking “what – ifs” questions. Methods. System dynamics, a modeling method was used to develop the model. The iterative and group-modeling process included development of a quantified model (with a multi-professional design team, based on evidence from the literature, and a survey from stroke care experts), and validation of the model. Results. The dynamic care model developed included variables that are essential in modern care, such as patient-participation, care-planning, and teamwork. Conclusion. The presented generic model provides a framework for exploring, comprehending, and communicating complex ideas about stroke care.
