To me, this is the strongest argument for a centralised health system, such as the UK NHS. When you have one organisation responsible for health as a whole rather than just treatment, you can make better decisions. The usual example I give is that it's cheaper to give out the contraceptive pill than deal with pregnancies, but the same thinking applies to broader disease and health.
