No, this person is kind of right. It didn't really make sense to me, so I did some digging, and overuse is a big issue with healthcare costs, but it's not as simple as 'people need to stop asking for antibiotics!' It's a systematic issue that's affected from top to bottom. From where our (mostly privately funded) biomedical research is directed, to doctors overusing procedures that arent benefictial and underusing ones that are (plus all the factors on why that is), to patients being uniformed. It's been an interesting evening, but unfortunately, it doesn't seem like I've really found any solid answers on what to do other than 'more research', so it was an unsatisfying end.
