Then the electronic health records system began in Tuscaloosa, Alabama, at a smaller location. Then during the next two years we rolled it out across the country using what we called key sites, which were divided into 22 veterans integrated service networks. I think Ms. Patterson talked to you about that. Each of those networks had a lead site or a key site where they had a clinical champion and a team that actually did the implementation.
So the complete implementation of our electronic health record was about a two-year timeframe. Then over the last decade it increased incrementally over time with the components that are used, until finally seven or eight years ago it was mandated for complete use. We had challenges. For example, it was easier to get the primary care and medical physicians using the system than it was to get the surgeons to use the system. We had different challenges in different parts of the medical centre itself.
