OK, now *that* is an interesting point you make. It might well be worth to eventually introduce
the notion of "freezing" an encounter.

This could happen at an appropriate point in time after a new encounter has been started. However, I am not sure how much that really buys us because we are essentially freezing the state of the EMR anyways when we dump the database, hash the dump and have the hash signed by a digital notary. Which one of our users does on a regular basis. Such a signed dump hash includes all audit trail
information as available at the point in time of dumping.

The best answer to the above may be to be able to express the EMR as it existed for a particular patient at a certain point in time. If a patient last saw a doctor at 2PM August 5, 2008 and if the issue becomes what the doctor found, what the doctor advised, and what the doctor did as of 2PM on August 5, 2008 then it should be possible to provide an EMR export that expresses what was in the record at that point in time.

In other words, if notes which were committed at 2PM were subsequently altered later on the same day, or at some later point in time when news of a complaint or adverse outcome surfaced, it would be important to be able to provide an EMR export that included the normally-hidden audited versions, along with time stamps.

The module could optionally exclude entries altered or added after a certain point in time however these could be important if they included legitimate clarifications and could be simply ignored by the reviewer when irrelevant. The module could also optionally limit the export to certain selected issues of interest.
