  • All of the identified airway incidents contained at least one of the sequences shown above. We then selected all of the incidents that contained at least one of these letter sequences from the sample of all patient safety incidents submitted to the NPSA during the defined time frame. Incidents include a location field, and we excluded ‘intensive care’, ‘high dependency’ and ‘critical care’ from our search results.

  • For initials, all letter spaces and full stop combinations were included.
