I've used at least 4 EMR's including residency and medical school. I'm a little newer at this, so started with EMR from day one and never have used a paper chart. The downside is I probably write way too much, much more than any sane person would ever write by hand. (Side note: typing most important class from high school.) I found the VA system cumbersome; Logician worked well for a very large practice, but required a lot of 'clicky clicky', ECW took a solid 2 weeks of training to even get proficient, and that is for a fairly tech savvy doctor. I loved AC from the day I tried it. I could tell it was designed by people like us, that actually use it. I have the feeling as we go along that it is continually getting better. The bugs bother me, and are sometimes a real problem. But this is one company where you can actually get an American human on the line for tech support and a company that changes the program, making it better and better. I love AC - and to answer your question, it is easy compared to most!
