A paired comparison [A15] was performed of the four weeks immediately before intervention and the four weeks post-intervention. Table 3 demonstrates these values. [A16] The mean frequency of occurrence of adverse events pre-intervention was 0.25 with [A17] an SD of 0.5 in errors related to assessment while the mean frequency of events related to intervention was 0.5

and the SD was 0.58 for errors related to intervention. Post-performance of the simulation activity
