In 2013, the UK Government announced a major £3.8 billion healthcare initiative, the Better Care Fund. This funding was intended to be used within local health and care systems to drive closer integration, create new service efficiencies, support technological innovation and most importantly, improve outcomes for patients and people with care and support needs. This is a new experimental policy with no evaluation of early progress to date. In this position paper we propose that significant challenges lie ahead both in terms of developing new strategies for health and social care partnership development and also operationalizing these within new forms of collaborative professional working. We argue that a systems or sociotechnical approach can facilitate a better understanding of the potential challenges for integrating health and social care information systems.
