Of course, one way of looking at this is when we have an expensive drug prescribed when less expensive drugs are available, or when quite often drugs are prescribed when they should not be prescribed and when other non-pharmacological therapies—by, for example, chiropractors, physiotherapists, or social work counsellors—are often as effective, or more effective, without the side effects of medication.
To a certain extent, the fact that we have so much mis-prescribing of drugs is a failure of the health professions but also specifically of how we organize primary health care. We still have most family doctors in Canada working not with a professional team of social workers, physiotherapists, chiropractors, and others who could deliver non-drug therapies.
They also are still not working with electronic health records. Canada's record there is very poor compared with other countries.
