Sure. Our surveillance system on chronic disease does track chronic disease rates and risk factors across the country. So we're able to identify areas where there seem to be higher rates of certain diseases or risk factors, and therefore help our provincial and territorial colleagues by providing that data so they can target their efforts and so we can also target our efforts collectively toward improving prevention in those locations.
We're expanding the work of our chronic disease surveillance system to get a much better sense of issues around hypertension and cardiovascular disease. Our data systems on cardiovascular disease have not been as robust as we would like them to be. Hypertension is an important public health issue in Canada, and of course with an aging population we will see more hypertensive Canadians. The good news--and we learn this through our surveillance programs--is we're among the best in the world at controlling hypertension. So those Canadians diagnosed as having hypertension are getting the drugs they need. Their hypertension is being controlled. But rates of newly diagnosed hypertension are still on the rise, and that is the kind of thing that our surveillance programs tell us. They tell us about those particular risk factors we need to be putting a priority on if in fact we're going to be successful in prevention.
