Really, all we can do is echo what the previous speakers have said. Absolutely, education and training are paramount—not just a one-time shop, though. For appropriate violence prevention strategies and training, I think there need to be ongoing simulations and practice, but that is only one piece of the puzzle.
We absolutely need appropriate facilities for our elderly people. We also need specialized units for patients who are suffering with mental health issues. As well, there are systemic challenges such as overcrowding and access to appropriate treatment.
A lot of these issues also have to be addressed, but yes, ongoing education and training certainly are part of this.
I would just look to my colleague Moninder to see what he'd like to add.
