Importantly, policies on regulation and competition need to stimulate integrated care, which requires clarity for all stakeholders about how the rules around competition and integration will be interpreted in practice. The evolution of such models does not need to be standardised, and can be tailored to the specific health needs of local communities. A review of six initiatives1 considered successful in increasing integration found that, although they spanned five countries and differed in their design and payment systems, a common denominator was the high degree of bundling in their payment systems, with a single budget used to pay for multiple components of a person’s health and social care (Hagbjer, 2012). Several initiatives also integrated the delivery of health and social care in one organisation.
