CP-IS is a new data sharing system that is being piloted in certain areas. The idea of it is that it will provide very brief information for unscheduled medical appointments e.g. A&E, walk-in centres, out of hours GPs, paediatric wards, maternity units and ambulance services. The information shared is only for children on a CP plan or look after children.
This is a good development but it is still extraordinary how little data is available if a child crosses local authority boundaries. Of course safeguarding adults is even more woolly and there is no CP-IS equivalent for adults.
