The following table shows data collected on Never Events from 2010/11, the first year when data was available. Never Events are serious incidents or errors that should never occur if proper safety procedures are followed. Never Events Data was collected by the National Reporting and Learning System (NRLS) and the Strategic Executive Information System (StEIS) until 2013. Since April 2013 data has been collected from StEIS only. The data from these two systems are not directly comparable due to differences in the way incidents are identified and reported. The number of events, and definitions of events contained in the Never Event List, are modified regularly, so direct year-on-year comparisons are not appropriate. The data for 2017/18 is provisional and still to be confirmed in the annual data summary.
