Across OECD countries, two in three people aged over 65 years live with at least one chronic condition often requiring multiple interactions with different providers, making them more susceptible to poor and fragmented care. This has prompted calls for making health systems more people-centred, capable of delivering high-quality integrated care. Despite promising, mostly local-level, experiences, systems remain fragmented, focused on acute care and unsuitable to solve complex needs. Moreover, assessing and comparing the benefits of integrated care remains difficult given the lack of technically sound, policy-relevant indicators. This report presents the results of the first OECD pilot of a new generation of indicators to support international benchmarking of quality of integrated care. Lessons from the pilot call for further work on: (1) expanding work on indicator development; (2) performing policy analysis to understand cross-country variations on governance models and health financing; (3) upscaling data linkage; and (4) measuring care fragmentation.
