1) Caffeinated beverages (for the patients and visitors, of course). I'm so tired of people drinking a liter of Dr. Pepper and then complaining that they can't sleep. Conversely, the people that request a sleeping pill and then an hour later request a coke or cup of coffee.
2) Cable television. Instead, I think there should be a health care version of pay per view that forces people to watch documentaries about their respective primary issues and comorbidities.
Any other ideas?
