A total of 202,000 NHS staff were invited to participate in this survey by postal questionnaire. Responses were received from 101,000 staff, a response rate of 50% (compared to 53.7% in 2010). The results are primarily intended for use by NHS organisations to help them review and improve staff experience so that staff can provide better patient care. The Care Quality Commission will use the results from the survey to monitor ongoing compliance with essential standards of quality and safety. The NHS Commissioning Board will use the results to aid commissioning decisions. The survey will also support accountability of the Secretary of State for Health to Parliament for delivery of the NHS Constitution.
