This page forms part of a resource on medication related patient safety alerts issued  by the National Patient Safety Agency (NPSA) between 2002 and 2012 – more details can be found here  – you will also find links to resources developed by SPS to support the implementation of some of the alerts. Please use any material at those links with caution. NPSA Alerts were only updated to reflect changes in current safety knowledge or clinical care until the point their ‘action compete date’ was reached. Some of these ‘action complete’ dates for NPSA Alerts, Safety Notices and Rapid Response Reports are now over fifteen years in the past, and no NPSA publications have been updated since the closure of the NPSA in 2012.
