Hi Robert, The field name can be what you suggested - what I put in was a little generic. I certainly want you to be happy.
In case there are hospitals that do not use the alt_pid field, keeping it NULL would allow them to proceed. Attempting to copy into alt_pid the value in pid if alt_pid is NULL would bring in anomalies and clash with similar numbers in the alt_pid that were not NULL in the first place. Hence the UNIQUEness for alt_pid would have to wait till you decide how to use it when alt_pid is absent (multiple NULL alt_pids should be able to exist). What is now in place is just a place holder. Please give it some thought as to how hospitals starting anew entirely in Care2x would be able to use it alongside with hospitals that intend to use Care2x for only a part of their operations whilst relying on their own HIS for others.
