My reaction from a 4 provider mixed specialty/IM practice is this:
The 4 of us have different styles, and even philosophies of what the different sections of the chart should mean. Personally, my HPI is very narrative as is my plan, with other sections more granular. Highly granular reports not only annoy me but offer me little useful information. If I got, for example, a long list of nerve velocity times from you with no thorough interpretation and lists of suggestions, then I think the patient is poorly served no matter how many reports you can generate.
AC mixes fairly well with Medware, but not perfectly yet. We can live with that.
At the end of the day, I want a system that allows me to generate and store a record that says what I want in common english that explains my thought processes and plans clearly. All other considerations are secondary. AC does well at this.
