My facility just transitioned to Epic last year. It is quite a change up, especially if you are moving from a paper charting to a full EHR like we did. The training might not be all that useful, none of the trainers that did our training were nurses, just training/education specialists. As with many other things in nursing, the best learning will be done hands-on, in the trenches so to say. Be prepared for a big learning curve. One of the biggest obstacles that many nurses found was moving to a EHR they lost many of the "prompts" or reminders that they had in a paper-based system. Blood transfusion charting is a bit wonky at times, even now. Expect many things to be not quite configured for your work flow or your specific hospital policy. It really works well once you get used to it, and the legibility of progress notes and orders almost makes up for the inconvenience of learning a completely new method of charting. :)
