One in 10 Canadians are not able to adhere to their prescriptions due to the cost of prescription drugs, found Michael Law et al. in the Canadian Medical Association Journal. But more than just numbers, the study asked who are those one in 10 and found something truly troubling. The people in Canada who are the most unlikely to adhere to prescription medication due to cost are: those who do not have drug insurance (public or private), those who earn the lowest income ($20,000 or less), and those who are in the poorest health or have multiple conditions -- in other words, those who could benefit the most from pharmacare.
Our need for pharmacare
Two-thirds of Canadians pay out-of-pocket for prescription drugs each year, which totals $4.6 billion or 17.5 per cent of total spending on prescription drugs. Almost 10 per cent of Canadians reported not filling or renewing a prescription or trying to make a prescription last longer because of out-of-pocket expenses.
While 26.5 per cent of people who reported cost-related nonadherence to prescription drugs had no drug coverage, 6.8 per cent of Canadians who did have drug insurance reported cost-related nonadherence. This meant that lacking insurance was associated with a four-fold increase in the odds of cost-related nonadherence to prescription drugs. Not having drug insurance was the largest associated factor with cost-related nonadherence. This is also the area that the study's authors found to be the most amenable to being addressed through changes to public policy.
