UKHSA National Patient Safety Alerts
National Patient Safety Alerts (NatPSAs) are official notices giving instructions to NHS bodies on how to prevent risks which might cause serious harm or death.
NatPSAs are only issued for safety-critical reasons that will impact on patient safety, with strict criteria.
The threshold is 鈥榤ore likely than not of one or more potentially avoidable deaths or disability in healthcare in England in a year鈥�.
NatPSAs are targeted at senior management in healthcare organisations for system-wide action, sent through the Central Alerting System (CAS).
The UK Health Security Agency (UKHSA) is accredited to publish NatPSAs to ask healthcare providers to take action to prevent or reduce the impact of a threat to public health from:
- communicable diseases, such as outbreaks of infectious disease, microbial contamination of products (but not medical devices)
- non-infectious hazards, such as exposure to radiation and chemicals
- supply disruption such as vaccines
In line with UKHSA鈥檚 responsibilities for public protection, the organisation will, from time to time, need to issue such alerts.
