I suppose this is dependent on how much you trust the doctor(s) in question, but, in general, a specialist I trust 'filling out a form' is somewhat reassuring; there's nothing sufficiently bad that they're breaking routine.

When programming, something that makes you think "yup, I'll do that as soon as there's time" is much better (for planning/PM) and more routine than "hmm, not sure, I'll try", right? I think the same applies to personal medicine - routine and boring forms are better than puzzled investigations.
