 This paper examined the development of integrated care, IC, policies in Belgium over the past decade. It found that the 2014 state reform had led to a fragmentation of decisive power, which undermined efforts towards IC. This political trend towards fragmentation was at odds with the need for IC. Further research is needed to understand how public health policy competencies and the durability of IC policies would evolve.
