Local Authority ‘Children Looked After’ (CLA) data is linked with health data that is held in the NWL’s Whole Systems Integrated Care (WSIC) platform, to help better understand the needs of children within a Local Authority. Bi-borough and Harrow are piloting this data sharing, with IG already in place and approved to enable the data to be shared directly to WSIC. Combining this data will help improve developmental, safeguarding, and wellbeing outcomes for children and young people, by providing analysis which gives a more informed understanding of children and young people. Analysis of the impacts of the wider determinants of health would also be possible, helping NHS Practitioners, DCSs, and their teams to identify and prioritise opportunities for development and improvement of the service offer, to best support the most vulnerable children and young people and their families. Specific use cases could include: •Understanding the health needs of children in contact with children’s services, by analysing specific health events experienced across cohorts, such as, long-term conditions e.g., Mental Health, and A&E visits. •Geographically mapping the level of need within a Local Authority, using the combined data to inform the level of need, using data points such as the proportion of children: in contact with children’s services, with mental health conditions, visiting A&E, with care plans.
