There is a common social misuse of the word 'trauma' to apply to an emotional rather than physical event, but it really means, an actual injury from an external source. That's exactly the kind of thing ACC, and probably your employer, wants you to be more aware of.
This article has some good information about common causes of trauma from a project aimed at bringing together various data sets (St. Johns, Police, DHBs) and use them to help predict and therefore try to reduce trauma. Worth a look.
New insurtech start-ups and trends to watch among the world's leading insurers like this kind of data. They want to build hyper-personalised context sensitive insurance/risk services that you can interact with. "Should I ride on a quad bike?" You might ask your smartphone, and the machine tells you your risks, and may offer management and mitigation strategies.
