Abstract
For organising person centered care, an important issue is how to deal with scale. This addresses what to organise on what level (in the neighbourhood, local, in the region, or national). With the increasing complexity of organising integrated care in networks, scale issues are an ingredient of integrated care governance. However, there is a lack of empirical studies that treat scale as an object of study in itself. Scale is an outcome of the interplay between many different interests, values and perceptions of people involved in the broader social and political processes. Five factors for suitable scales are discussed, emphasising the relevance for integrated care governance. These factors show, that the classical micro-meso-macro thinking oversimplify reality and more knowledge about suitable scales is required.
