The design of the VistA system anticipated the requirement to create new
data elements (fields) indefinitely into the future.  VistA provide for a
formal method of allowing for the addition of data elements without adverse
impact.  It is, however, a matter for competent (master craftsman)
personnel.

Likewise, the underlying M(UMPS) technology does not carry a penalty for the
presence of unused data elements in the database.

There is, unfortunately, no easy remedy for the problem of how new data
elements appear in the application software dialogs and processing there of.
The presence of unwanted dialog related to data elements not being used,
such as SSN, is also an significant problem to be overcome.

Any existing system that presents the difficulties about which you are
asking, Mark, will require some substantial investment to adapt to your
specific circumstances.

The question is:  Which SET OF PROBLEMS to you want to be working on?

Choose your poison, Mark.  ...but, drink some poison you must.  :-)

Regards,

Richard.
