National Health Service (NHS) England conducts annual assurance of NHS bodies in England’s readiness to respond to emergencies using its Core Standards for emergency preparedness, resilience, and response (EPRR). This review assessed whether the first complete EPRR assurance after England’s coronavirus disease (COVID-19) pandemic national response was performed successfully.

The primary outcome of interest was the quantity of information regarding applicable Core Standards held by NHS England at the end of that assurance. Secondary outcomes were variations between the number of applicable Core Standards and information held by NHS bodies about the number of applicable Core Standards.

NHS England recorded the correct number of applicable Core Standards for 88 of the 124 NHS trusts in England which provided general hospital accommodation and services in relation to accidents or emergencies. It recorded an incorrect number of standards for 13 trusts and did not record the number of standards for 23 trusts.

NHS England’s EPRR assurance resulted in correct data not being recorded for over a quarter of the above NHS trusts. This review may also be of interest to other state-level bodies that rely on the high-level assurance of their ability to provide health care during emergencies.
