The interim auditor general says he was shocked to see the difference in price that some regions are paying for prescription drugs compared to others.
Michel Samson compared two groups that negotiate the price of large batches of drugs for Quebec's hospitals. There are four groups who conduct this work for different regions of Quebec.
In a third of the cases he looked at, the price difference for the same drug was 10 percent or higher.
In one case, one group paid 892% more than another for the same medication.
"Yes, we were shocked by the size of the difference, it's sure," says Samson, who said the price difference can not be explained by the volume of doses being bought.
He says the different groups do not discuss with each other what they are paying for drugs. And, he says, no one in the health ministry is doing that for them.
