The most recent version is easy to use, has great features for data collection like demographics or patient surveys as well as other useful tools such as tracking medical appointments with patients.
While it's not necessarily difficult to figure out how some things work (or lack thereof), there isn't any "getting started" type guide available at this time which would have been helpful in getting up-and running quickly. I'm working within an HIE trying to get our providers connected so we can better understand their usage patterns/utilization rates across multiple facilities - all while using very limited resources due to budget cuts by state governments.
