Investigations

We can investigate patient safety concerns that occur in England during the provision of healthcare services, and that have or may have implications for the safety of patients.

Our investigations can consider healthcare provided in the NHS and the independent sector. Where an investigation relates to an incident that did not occur in the NHS, we must consider whether NHS systems and practices could be improved because of our investigation.


We can also be directed to investigate a patient safety concern by the Secretary of State for Health and Social Care.
