Things have changed over time. I can tell you how things work right now with prescriptions provided on base. We have a system that, whether a prescription to a military member is obtained in a civilian pharmacy or on base, it is entered into the same system, as long as the individual uses his or her Blue Cross card when they go to a civilian pharmacy.
These things are all tracked through a single system, but we have not had that system throughout our history. We've only had it the last 10 or so years. Nothing is foolproof, but I do think we're in a much better position now than we were in the past to track these sorts of things.
We also have an electronic health record now, since the mid-2000s, which also allows us much better access to information. Previously, when we were using paper-based records, things would be entered there and sometimes papers would get misplaced, as can happen. Now, with things being entered directly into this electronic health record, it is a permanent record that clinicians have access to no matter where the patient is working.
