Gil,
They don't enter edit mode unless they are entering data or really needing a complex view of the history.
Al,
They don't have to give a reason for deacivation of a problem, just a medication. They usually add comments in the deactivation reason if they have time.
The product is relatively simple in that you can get data into the history of a problem many different ways, but in the end you can view the history with just a double click on the problem and then review in Chronological Reverse Order.
Here is a screenshot of the problems for 20 items on a elderly real Cardiology Patient Deidentified for a 180 patient a day 6 provider Cardiology Practice:

And by double clicking on a problem, like I did on the Blue Highlighted Item there, you can get the history for the item. By right Clicking you can add items to the problme. Of course there are many different places where this commentary and history gets updated. Here is the history, double click, less then a second, then Ok button to close. I don't really see many of our physicians clicking every Gosh Darn problem in the list. Oh looks like you had Chicken Pox, let me see when you had it was it age 8 or 9. Yeah right.

Gil, our practices can configure or add any problems they want to the Practices, Individual Physicians, or All category. It is easy for say the primary care provider to have one diagnosis for unspecified condition of the heart and for the cardio doc to have 10 entries custom for the same diag code, unspecified condition of the heart.

I think again we are talking 6 one way and a half dozen another. In the end though all these data elements are used in many different places in different ways by different practices. So the EMR has to be able to accomodate all these different users needs, not be built around any one mans concepts.
eMedRec is the compilation of ideas from over 50 active Beta Physicians. In reality we don't know crap about Medical Environments (After 18 years we have learned enough to be dangerous), that is why we let our users tell us what the hell they want and we build it for them after concensus from nearly all the providers.
