Integrated care programmes are increasingly being put in place to provide care to older people living at home. However, knowledge about further improving integrated care is limited. In fourteen integrated care sites in Europe, plans to improve existing ways of working were designed, implemented and evaluated to enlarge the understanding of what works and with what outcomes when improving integrated care. This paper provides insight into the existing ways that the sites were working with respect to integrated care, their perceived difficulties and their plans for working towards improvement.
