Hi list,

It has been very interesting for me to follow your discussion about
modeling of health data. I do not have a much health-data-specific
experience to offer (yet), but I do recognize a few patterns from modeling
in many other domains.

Allow me to pitch in with an idea for solving the specific problem in this
thread.

Why not always allow free-text and ask the user to use her own words first,
then ask to pick from a set of restricted classes incl. the famous 'other'?

I understand there can be reasons that has to do with 'effective typing'.
It might be faster to pick from a list of codes, than to write a few words.
But I think a well-designed html-application would allow a user to click
the text field, type in a few letters, get suggestions from previously used
phrases, then tab on to dropdown next to, select from a list of available
classes and then move on.

Another argument against "free text first, then selection of class" could
be the unease of free text in registers and databases. But I would consider
the free text a very valuable piece of information and I don’t see any
reasons not to collect as many as possible. They don't cost much in terms
of either bandwidth or storage in modern it-systems.

What do you think about this idea?
