What is the Healthcare Safety Investigation Branch?

Our investigations look at factors that have harmed or may harm NHS patients. We work closely with patients, families and healthcare staff affected by patient safety incidents, and we never attribute blame or liability.


Our investigations are delivered through two programmes: national and maternity. There are differences in how they are carried out and how reports are published but the aims are the same: to share learning and to make safety recommendations that improve safety at a national level.
