What column will this be?
clin.substance_intake.is_long_term
Is it better boolean as above or would it be better to be categorical
clin.substance_intake.category
values {short-term, long-term, NULL} default = NULL
Also in this table, I wondered for a moment I wondered
whether .duration could take either an interval-based value (when
known exactly) or when not known exactly could take the value of short-
term or long-term
I suspect the data type "interval" would allow only a time-based value
therefore it would have to be some other field.
That would beg the question as to any conceptual +- programmatic
interaction with duration?
IOW:
if duration is null, the category of medication could be short-term or
long-term
if the medication category is long-term, does that mean the duration
should be nulled?
do we acknowledge potential ambiguity between
duration as "intended"
duration as "elapsed time since started .clin_when"
duration as 'how long did they take it, if they stopped on or before
today"
if a duration is specified and is understood to mean "as intended or
post-hoc actual", should a specified duration be construed to mean
short-term, or maybe still the medication could be intended as long-
term with the duration used to pre-specify a plan of reassessment?
If the latter, then there would be neither conceptual nor programmatic
linkage between duration and category, and the meaning of duration
should be clarified to be
Intended duration of use (whether total, or until reassessment), or
actual duration if stopped, if known
