[...] To find out about the experiences, challenges and insights of using data to effect system change in the long-term care sector in Ontario, we taped semi-structured interviews at the beginning, midway through and at the end of the study in the intervention sites and at the beginning and the end at the control sites. [...] Thus we aimed our program of research at understanding what conditions and factors support the diffusion and sustained implementation of evidence-informed practices and models of nursing services across the healthcare system. [...] During the symposium, we learned about other models of systems change being introduced including the Blueprint for Health in Vermont, USA; and reforms in Adelaide, Australia and the National Health System in the UK.
