Introduction (short description of the SIG to include in the Conference Programme) The SIG 'Evidence Based Integrated Care' is for healthcare researchers who are interested in support healthcare professionals with joined evidence for effective interventions and evidence for effective application in Integrated Care trajectories. Earlier with the members of this SIG, we debated that Integrated Care is aimed at well-organized, cost-effective processes of care delivery, provided by committed professionals which must be able to count on well-established evidence for the care interventions they provide in integrated trajectories to their patients. In providing a reference for research for creating knowledge supporting integrated care, the SIG members defined 'Evidence Based Integrated Care' covering the description of the care problem with the underlying working mechanisms, the test acceptance by patients and care providers, of both the concept of interventions and the (cost) effectiveness in the context where the complex interventions are provided. It also covers the organization of the complex interventions in the trajectory and the quality of life and societal participation of citizens or patients. Aims and Objectives Citizens want to feel supported in being able to participate as optimally as possible in society with the highest possible quality of life, at the lowest possible cost (triple aim) and with more meaning for care providers (quadruple aim). In the meantime, citizens' care needs are becoming increasingly complex, still mostly approached by more individual acting professionals at the same time resulting in fragmented care. In research regarding evidence base integrated care, practical questions are asked about the contexts in which the care under study must be provided or to which the context under study must be adapted. As such in research for evidence base integrated care for integration knowledge there is thus a constant balance between practical orientation and theoretical orientation. This concerns the ""proof in context"" (care provision) versus the ""proof of concept"" (care content). In this session we will discuss the meaning of incorporating both the perspective of ""proof of concept"" and the ""proof in context"" in integrated care research. [ABSTRACT FROM AUTHOR]
