There is an increased focus nationally on how to improve access to data whilst maintaining the highest standards of security and confidentiality. Secure Data Environments (SDEs) are data storage and access platforms. Dr Sian Rees, Health Innovation Oxford and Thames Valley’s Director of Community Involvement and Workforce Innovation, chairs the Thames Valley and Surrey Care Records ethics and advisory group and has been funded to establish an SDE, owned and run by the NHS, covering Buckinghamshire, Berkshire, Oxfordshire, Milton Keynes and Surrey.
