Difficult and contentious, but it needs to happen
It is difficult to reach solid conclusions from the data Paul. Although rich, the data is a small subset of the big picture, and the meta data released by CMS is so limited that it certainly doesn't help the enthusiastic amateur either. But, as you say, something has to be done about runaway healthcare costs. Shining a light, however weakly, onto the economics is one step. Without tranparency and competition there will be no change. So a bold move by CMS, but hopefully this is just the start with more datasets and more detailed data to come.
