Balance of Power

Actually, in order to be able to build Battlefield Medicine, you need at least 5 hospitals in your cities. It's useful even on higher difficulties, too.
Personally, I don't usually go researching Medicine->Sanitation. I play with slightly looser placement, CxxxC with some CxxC in the mix, so some cities can have more than 12 tiles and hospitals is of great benefit. If I do get Sanitation, I'll build hospitals in cities that can grow productively. But if I don't get it, then I don't.
I believe most people don't go for Sanitation due to the nature of CxxC spacing that doesn't allow a city to be able to grow past size 12 without some food bonuses. A hospital is no good if the city can't produce enough food to support 13+ population. Plus metropolises produce pollution, and I can imagine some players would rather not be bothered with pollution popping up every turn. Being able to grow past size 12 is a boost to commerce and production, but with that growth you'll need to pay attention to happiness issues; bigger cities are harder to keep happy. Battlefield Medicine is nice (very nice) but is by no means a gamebreaker IMHO.
