If you're not an ACRO member, you should be. Per the introduction last night, these slides and this presentation will be made available to members.
Personally, I found the following slide most striking (credit to ACRO and Health Management Associates):

The Y axis is "percent change in episode payments", and the X axis is "number of services", which essentially means number of fractions. Graph on the left is conventional EBRT, graph on right is IMRT.
People are going to do what is incentivized, which is ostensibly the point of this model - under FFS, more fractions was incentivized. Looking at this, under APM, the exact opposite is incentivized. A 28.4% increase in pro fees if I keep it under 10 "services" (fractions)?? As people have rightly pointed out earlier in this thread, 5 fraction regimens for Medicare patients using non-IMRT EBRT are going to TAKE OFF in popularity, regardless of the actual strength of the data.
This is the government telling us, with our wallets, how we should practice medicine, in a ridiculously heavy-handed manner.
