The Child Health Interim Application (CHIA) is currently live in 10 primary care trusts (PCTs) in the London area. Supporting manual systems continue to operate for some aspects of the system's functionality, which remain under development. Software to enable PCTs to generate COVER reports from the live system is expected to be deployed into the live system in April 2007. Meanwhile, COVER reports for each PCT, using live CHIA data, are being produced centrally on a quarterly basis in line with Health Protection Agency submission requirements. However, due to a backlog of data, which have not yet been loaded on to the CHIA system, some PCTs have requested their data are not published until local data quality queries have been addressed.
Successful deployments of child health systems by the national programme for information technology have already taken place in 48 PCTs across the programme's north-east and eastern cluster areas. The system enables production of the required statutory reports, and a robust data migration and checking procedure is in place, ensuring successful migrations of demographic and clinical data to the new system, which provides a fully integrated patient record across primary care. Experience has shown that the key variable around successful implementation and operation is the quality of local record keeping standards and processes.
