Do ADT^A11 msgs cancel/discharge all messages for an acct?

Jun 2, 2011

Acct = account? And account = admission. I presume. On that basis, the definition of A11 is :

For “admitted” patients, the A11 event is sent when an A01 (admit/visit notification) event is cancelled, either because of an erroneous entry of the A01 event, or because of a decision not to admit the patient after all

Well, the A11 is for either where it was an erroneous entry, or where it was a real entry that was cancelled due to real world events.

In the first case, it’s gone, and will never be heard from again. In the second case.. maybe. This is where it depends on the way the implementer of the sending system reads the spec, and their problem.

I **think **that having sent an A11, that should be it. No more messages on the episode, and a new one created.

But what if the A11 itself is sent erroneously? There’s no cancel a cancel message, so it’s unpredictable whether a system will use some other event to magically bring it back to life, or go with a new admission. And since there’s no real clear definition of how to use PV1-19 (Visit Number), it may not even be clear whether a new episode with the same episode details is a different episode or not.
