..... It is especially difficult because you have no idea which EMR you transitioning to, and what it will be able to import. A generic .csv may be the best we can hope for as a bridge between the two.
AC gives you the option to create a .csv of all encounters, demographics, your contacts, and templates. You can also create a continuity of care record for all patients in CCD or CCR formats, which at least may be easy to get into a new EMR. While I have never done this, I don't understand what portion of that would require help from AC, as Wendell reports.
Ah, and there is the rub.
I remember more than one slick huckster sales pitch where vendors were trying to displace AC in a practice with several thousand patient records - the train always jumped the track when I asked if the pricing included converting all of the patient data.
