Our investigators are central to what we do. They oversee our investigations from start to finish. They operate independently of any other organisation, including the Care Quality Commission (CQC), Department of Health and NHS organisations.

Investigators work closely with patients and their families and carers, healthcare staff, trusts, hospitals and other healthcare providers in England. 

Their work includes: 

  • gathering information
  • interviewing anyone thought to be relevant to the investigation
  • preserving evidence within data protection guidelines.
