A "good catch-to-Serious Event" ratio was calculated by comparing the number of good catch reports (i.e., events submitted with harm scores A, B1, B2) to the number of Serious Event reports (i.e., harm scores E, F, G, H, I), creating a proportion that could be expressed as x:1, or simply x.
The ratio of good catches to Serious Events increased from 5.62 in 2005 (n = 33,777/6,008) to 10.34 in 2016 (n = 54,472/5,269).
