Ah, I see your point :-)
Here is the kind of data that I know would be useful for some clinicians I work with in the UK:
1 - symptoms from the last week (cough, breathlessness, sputum, nasal discharge, diarrhoea)
2 - effects on life: visits to physician, antibiotic therapy, days off work / school
3 - for home therapy, batch numbers medications and site and number of attempts for needle.
So my question is, what other kinds of data would your clinicians find useful, or would you like to collect as a patient?
