There's an actual program that Canada developed under the directorship of Dr. Barry Pless called CHIRP, the Canadian hospital injury reporting program. It doesn't exist in every hospital, but in the ones that do have it--primarily children's hospitals--they do collect the data. Once again, they're under-resourced to be able to take that information, package it, and give it with some prevention strategies to the people who can make the difference. You're absolutely correct. Other countries that have done this successfully have very robust surveillance systems. In Iceland, what they actually do is assign a bar code to every injury, and everything related to that injury is assigned to that bar code so they can actually quantify the costs of it. Your thinking is absolutely correct: a robust surveillance system. What's missing now is that information needs to be analyzed and then fed back to the community.
Ideally, if we had Paul Kells in every community, it would save communities, and that would be the group that would receive that information, do something, and then the surveillance group could measure if it's having any impact.
