I wonder how much this is solely technical. Sure, if it's something like asthma medication or insulin, its' completely superfluous. But if I remember correctly, doctors have a few incentives for this. Part of them rather good, like a fear of over-medication, part of them related to budgets with the insurance companies etc.

The health industry is very weird from top to bottom. True for most countries, but Germany certainly adds a few cherries on top. Or at least massively diluted cherry essences…
