Privacy statement

The NPDA has section 251 approval to collect patient identifiable data without explicit patient consent. This data is processed and reported by the NPDA team at RCPCH, with HQIP (Healthcare Quality Improvement Partnership) as the data controller.

HQIP may approve the sharing of pseudonymised NPDA data for the purpose of academic research if stringent data protection policies and arrangements can be demonstrated by requestees and the aims of the research are approved. NPDA data will also be linked to Hospital Episodes and Statistics data produced by NHS Digital and the Patient Episodes for Wales supplied by the NWIS in order for the audit to produce reports on diabetes-related hospitalisation of children and young people.
