what is the difference between

        "who's seen something in the first place" (a)

and
        who has reviewed
        (as in seen by *a* human being) items (b)

Are you asserting
(a) asks for each *user* "What have they seen" whereas
(b) asks for each *test result* "Which user(s)" have seen it?"

and are you designating that (b) cares only to capture a single user, 
who sets "reviewed_by_clinician" to TRUE

On the related issue of "reviewed_by..." (or even viewed by), is 
there agreement that the schema may need to capture a proxy user?

I am thinking a doctor may order tests and have to leave the office 
and later, because they know to be concerned, they want to access 
their gnumed but cannot do so from out of the office (forgot their 
USB key, or network "down", or the lab actually phoned the office to 
report a "panic value", so the office pages the doctor. The doctor 
asks their secretary "please look up and report Mrs Smith's results 
to me over the telephone". So in the schema as it exists:

- would a secretary have access to view a result?
- if not, can a secretary be permitted access, by a method in which a 
doctor gives temporary authorization and through that audit, both the 
secretary and authorizing doctor are captured.  So if this is agreed 
important, would it be through the front end that the secretary 
identifies from a pick list which doctor approved?

- would we want, in the user privilege schema, a field that that 
defines whether a particular non-clinician is eligible for that 
privilege (for example, you may permit a member of regular staff but 
not a new worker who has not yet proven their level of responsibility 
or trust)
