I don't do clinical research any more, but occasionally I come across questions that might produce a cheap, interesting and publishable study.
What percentage of parents run out of their child's liquid antibiotic medication prior 24 hours early? My guess is that the percentage is over 70% due to normal loss, spillage, and over accurate dispensing.
Simple study, publishable unit.
For extra credit, what are the financial incentives for "precise" dispensation of liquid antibiotics?
