Clinical audits and registries

NHS England runs clinical audits and registries for the health and care system in England. We help partners like the Department of Health and the Healthcare Quality Improvement Partnership compare the performance of health and care services against standards and national trends so that they can improve patient outcomes.

Clinical audits and registries are developed and delivered by the Clinical Audits and Registries Management Service (CARMS), working collaboratively with clinical specialists, patient representatives and universities. We are commissioned by various organisations, including government, charities and academia.

Clinical audit is a way to find out if healthcare is being provided in line with standards and lets care providers, commissioners and patients know where their service is doing well, and where there could be improvements. The aim is to allow quality improvement to take place where it will be most helpful and will improve outcomes for patients. Registries collect data about the health status of patients and the health care they receive over varying periods of time.


Go to the Clinical Audit Platform page to find out how to submit data to our audits and registries.
