Yes. I think that we need better sources of data than we currently have.
For instance, in most provinces there is no single source where you can find out prescriptions that have been dispensed. British Columbia is an exception. Their PharmaNet program records every prescription that has been dispensed, regardless of who has been paying for it. That kind of information, coupled with the hospital and outpatient databases that we have, could certainly help in providing more information about drugs that are being used and their adverse consequences if they occur.
