The user interface of docBook MD was very easy to learn. It has all the features you need in an EMR system with the ability to link patient data from multiple sources. I found it difficult at first getting used to how everything worked but once i got over that hurdle its been great! There are many different ways to customize your program so there really isn't anything bad about this software. We use this tool as our medical record software which allows us to access patients information anywhere we have internet access.
