Unfolding this means that past history is anything that came
up during an encounter (eg it was the title of an episode) and
later was deemed significant enough to keep around for one
reason or another. Which would mean it had become a
clin_health_issue. Good. (Note that not everything need to
have come up in one of *our* encounters. They patient may just
tell us about it, eg. relate what is traditionally known as
"past medical history".)

I agree. I would, however, enhance that last point to
"anything new that has come up pretty recently and is not
closed yet" - IOW a clin_episode that isn't closed yet.

Sure, the current progress note input widget - ugly as it may
be - allows to create new episodes. I am currently working on
allowing it to create clin_health_issues (IOW past history
items) when the keyword "phx" is typed in (will pop up a past
history edit area).

If formattable in advance what would be the point in delaying
the import until the encounter ?

If imported during the encounter why would we want to use a
"file format" instead of a widget ?

IOW what is the *source* of phx items you are referring to,
here ? Another - legacy - EMR ?

Absolutely! In fact, we (Carlos and me that is) are combining
several concepts brought forth and laid foundation for by the
fine works of Richard and Ian: The resizing STC SOAP widget
with keyword popups, the edit area and the phrasewheel. In the
SOAP STC a keyword would popup an edit area of PHX which would
contain phrasewheels to facilitate rapid, context-supported,
dedicated input of PHX items.

Another place to allow adding/deleting/moving/modifying
episodes/encounters/issues is the EMR tree. Foundations for
that were laid by Syan.

Exactly. I am trying to find out (and getting confident that it
is) whether a clin_health_issue is sufficiently identical to a
past history item. It so seems given the additions I already
made to clin_health_issue (age_noted, is_confidential*,

 * until better implemenatation of confidentiality in 1.x ...

Sure but is there value in capturing the "has been operated"
state in a dedicated field in the backend as opposed to simply
naming the past history item (eg clin_health_issue)
appropriately, eg "s/p appendekt (Crohn)" vs. "s/p appendekt
(post-abdo-pain)" ?  The advantage would, of course be to be
able to reliably *query* on the state of that operation flag.
Is that worth it I ask ??  If clinicians jump up and tell me
"Why of course! Because..." I'll attribute this to my newbie
state in medicine and add the field to the backend. I suspect
there is value because Richard does have the field. That's why
I am so stubborn in asking for the reasons.

Most definitely. In fact, the current (eg. 0.1) implementation
does not really attach codes to rows. It simply provides
code/system combinations associated with a term (free text) -
which then just happens to match a given narrative somewhere
in, say, a soaP row.

Sure, in that case I'd add a clin_health_issue
"s/p appendectomy (elective/Crohn's)". Richer descriptions as
to the how, why, and when could be attached to that health
issue via some proxy episode (closed) linking a few SOAP rows
as needed.
