I think it's a challenge across injury issues, but certainly for concussion and the way that data is collected, we always see the tip of the iceberg. At the FPT working group, we have talked a lot about what systems already exist that could be leveraged to collect the data that is out there. What are sport organizations collecting and how can we access that or not? What are the barriers and facilitators to that?
It is a challenge across the board. I don't think any country has solved this issue around access to get a clear picture about the number and severity and, as Dr. Zemek said, the period of time concussion can take, in order to understand the real picture of the burden of concussions in Canada. I would say that as part of that research and evaluation, this is an essential component that we are missing in terms of understanding the data very clearly.
Now, data will tell us one thing. It will tell us how many. In prevention, what we also need to know are the contextual pieces of information to understand how the injury occurred. By knowing that, we can direct the prevention strategies so that we are not looking for solutions that aren't even part of the problem.
I would encourage both the numbers collection, in terms of absolute numbers, and also the contextual information, so that we can understand what solutions can be put into place.
