We know that about 6.5% of hospital admissions in Canada are the result of non-adherence, or people not taking their medication. In light of the present over-capacity in hospitals, to decrease that by 6.5% would be significant. In Canada, non-adherence is estimated to cost between $7 billion and $9 billion per year. In the U.S., the costs are $100 to $300 billion in avoidable health costs. That has been costed out, and there is a large cost attributable to people not being able to take their medications.
