According to the Institute of Medicine:
- More people die each year from medical errors than from motor vehicle accidents, breast cancer or AIDS.
- From 1983 to 1993 there was a 250% increase in the number of deaths caused by medication errors.
- As of 2008, JCAHO reports the number of Sentinel Events (unexpected deaths and serious injuries) reported each year continues to rise.
Conversely, in the Nuclear Power Industry, since the Three Mile Island accident in 1979, the World Association of Nuclear Operators reports:
- The number of significant events continue to decrease and is 45 times lower today than in 1989.
- The Industrial Safety Accident Rate (workplace injuries) is nearly 10 times lower than it was immediately following the Three Mile Island accident due to error reduction practices.
At the same time safety has improved in the Nuclear Industry, production costs have gone down.
