I can just add a very small anecdote from northern British Columbia. We don't live in the far north, but we certainly have challenges with turnover.
I totally agree with what Jake and Gwen have said about the challenge of practitioners coming in who don't know the context of what they're stepping into. One of the things we've done is we have small groups of communities across the upper two-thirds of British Columbia. They're almost like in traditional groupings. We engage with them, as the Northern Health authority. I also work with them. One of the questions we ask them as we prepare for these folks coming into community is, “If I was a new health practitioner coming to your community, what would you want me to know?”
Northern Health has supported them in developing resources, and we have all kinds of resources now: DVDs, elders speaking, and all kinds of teaching materials to start to mitigate some of that in-and-out stuff and give them some background before they actually get there.
