Our data comes from Canadian sources only. There are multiple levels of data. We get expenditure data from every province except Prince Edward Island, so we know how much a province has paid for each drug under the public drug benefit plan. That data's fine for looking at trends and spending on each individual drug and so on, but that's not really where the power of the research is.
The next level is where you have an anonymized patient code. They scramble the patient codes so no one can identify who the patient is. Every time they send us data, which is usually daily or weekly, it has the same patient code on it, so we can track people over time. You can see the dosage people are taking, which drugs they are taking, whether they are on more than one medication, and whether they have quit taking a medication. We get the same kind of information from about 5,000 or 6,000 pharmacies in Canada. That's the difference in the data.
We get those data for our analysis from two provinces, one federal organization, and just about every insurer in the country, and that's what the reports have been built upon.
