Increasingly, countries are integrating personalised public services to enhance access to, and the experience of those services to significantly improve outcomes for service users. Integrated services are particularly valuable for those with multiple and complex needs who require a range of tailored and, in some cases, specialised supports and services from more than one agency or service provider. Service specialisation can make it difficult for these service users to get the right mix of services and at the right time that best meet their needs. This paper provides a summary of how countries are integrating services to improve the lives and outcomes of care experienced by young people, people with disabilities, and people leaving prison. The paper is intended for policymakers who are seeking new or improved approaches to improving the outcomes of those who rely on personalised services.
