Actually, we're NOT a hospital. I work for a company that does medical case management, and a part of that is indentifying members who have continuing problems and complications, because those people might be appropriate for case management.

As for the test data, I agree totally. Unfortunately, I'm not the DBA, so I don't have any control over that. However, I can tell you that having test data in the production database has been an issue here. That data was entered by a nurse/trainer who had no understanding of why test data in a production database is a bad thing. That kind of thing is no longer being done. The DBA says that the test data can not be removed. I'm not sure why.
