Dear Smart People -
I would be interested in your take on a chronic issue - when is it really safe to have two users in the same chart document at the same time. I have reviewed all the Centricity help topics (we are on CPS 12.0) on concurrent access and it doesn't all ring true. The main thing I want to avoid, of course, is losing any data due to concurrent use.
Our experience has been - adding in-house lab results (using a VFE form) is safe, but entering vaccines (using a CCC form) can be problematic.
What patterns have you smart people noticed?
Thanks, Harriett
To clarify, do you mean 2 open updates in the same chart, or 2 users in the same update?
I believe ours (also CPS 12.0) consistently indicates an update is locked when another users is actively editing. I don't think there's a way around that other than by releasing the document locks in the database.

To clarify: I am most interested in two concurrent users in the same update. Thank you.
Others may disagree with this opinion re: Centricity, but being the cautious type I would advise one user in an update at a time. If you think about a real life example a patient has a paper chart and it can only be accessed in one spot at a time. If you have more than one user in the visit at the same time, entering the same data point at the same time, whose value wins? You start moving down the road of having issues with the ACID properties of the database.

Others can speak more authoritatively on how Centricity manages database consistency, but I imagine, this is why there are document locks at times during the visit.
