Short report of joint event organised by London Health and Care Integration Collaborative, SCIE and PPL on the theme of joint working to deliver better care. The event was attended by over 70 people in London with an interest in or involved in delivering integrated care. It aimed to enable participants to hear the views of experts, share learning and practice about what works, and learn about practical steps they can take to develop joint working and ensure it works effectively. Areas covered included developing an effective communications and engagement strategy, leading co-ordinated, co-located teams, and co-producing change with people who use services. The report provides summaries of the plenary sessions and discussion at the event. Key messages include, that: prevention, early intervention and integrated care are all linked; leaders are able to look beyond their own organisation to the needs of the system overall; we need to see communities and people as assets with contributions to make; and that getting staff buy in and valuing staff contributions and ideas is critical.
