I can give you a partial answer to your question partly because we lack the central data that would be necessary in order to properly answer your question, and that must be remedied.
What we know is that just through identifying people with prediabetes and offering them a proven coaching program to help them manage their weight and physical activity and thereby reduce the risk of developing diabetes, we can prevent nearly 60% of them from going on to develop type 2 diabetes. That would amount to, in Canada, about 110,000 people a year, or a million-plus people over the next decade. If we prevented them from developing diabetes, we could prevent, according to studies, at least 5,000 lower limb amputations every year and at least 35,000 hospitalizations every year in Canada. That would save us about $18 billion over the next 10 years in health care costs associated with treating people presenting with type 2 diabetes, by treating those amputations and the ongoing rehabilitation, and the cost of those hospitalizations.
I should say that's using an average cost per hospitalization of $6,000, which is very low for what most people with acute diabetic ketoacidosis or on dialysis would require.
