In this case the result is basically useless. AFAICT this is quite rare.

IMHO it would only be doctors who do "create new patient" (as they may know 
this is a new patient,
for example they got a phone call)

In Australia
        - there is no offical number which is guaranteed unique to any 
(families can share a single number), plus an individual is identified to the 
by several numbers (I have 6)
        - no number which is common to all citizens. Foreigners, ncluding 
longterm residents
also often have no number also.
Babies often don't get registered until they first present to a doctor
(they are not registered at birth and frequently remain completely numberless
until 3-4 months of age, often older in isolated areas)

We already have an unmatched_result table.
IMHO we should just add a simple flag so seen but unmatchable results can be 
(and brought back as the need arises)

Presumably unmatched results which hang around for weeks and weeks will have to 
be discarded
(but remain in the audit tables, so they are never truly gone)

we now have a "comment" field for this and other purposes.
