In 2017, England’s National Health Service (NHS) implemented the Learning from Deaths program which requires NHS Secondary Care Trusts (NSCT) to report, investigate, and learn from potentially preventable deaths. This study focuses on what NCSTs learned during the first three years of the program, the actions taken in response and their impact, and engagement with Learning from Deaths. Trusts appear to have varied understanding and use of the term ‘learning’ and not all specified the impact their actions had on patient safety.
