APEQPT: why do we ask when it's being completed when we know? And consequences.

[RudolfCardinal]

The APEQPT task (but not APEQ-CPFT-Perinatal) asks "Date & Time the Assessment Tool was Completed". This is a bit incongruous because

• creation datetime is automatically collected for all tasks, and this question is probably an accidental hangover from the paper version;
• the HTML server display doesn't show this field, q_datetime;
• I noticed it because the task framework doesn't prepopulate q_datetime (unsurprisingly), but the FHIR framework relies on that field for its standard datetime field, rather than when_created. So FHIR export crashes for this task in the unit tasks.

I'm working on the broader FHIR Questionnaire problem, but on this point -- should we just remove the question and field? It's something we ask the user that we already know automatically and it leads to some confusion. I don't think there is much real risk in deleting it from existing data (since it it effectively duplicates when_created), but that's the point most worth considering. (There is a free-text comments field, so we could even do a database migration that appends a string containing this date/time to the free-text field before deleting the superfluous one... but that may be unnecessary.)

@RudolfCardinal To me it doesn't make sense to have this as a question unless the dates and times are likely to be different from when_created. I can imagine a scenario where on Wednesday a clinician might create an electronic record from a paper questionnaire filled in by the patient on Tuesday, but this wouldn't apply to an anonymous questionnaire on a tablet filled in by a patient.

The FHIR export could just use when_created, couldn't it?

[RudolfCardinal]

Yes, agree. I'll alter the FHIR bit now, but the APEQPT will be a separate database migration so I'll hang on for now on that.
