What is the best way to control the escalation of medical charges

I asked this question in the Wisdom of the Crowd - What is the best way to control the escalation of medical charges

40% said we should set a medical fee guideline for each treatment.

36% said we should negotiate the fee for each treatment at national level.

24% said that the government should audit the fee charged for each treatment that exceed the benchmark.

None said that a co-payment should be imposed.
