A bone of contention with actual hospitals who see their ratings, and disagree with the weightings, and the comparatives, using the latent variable model. They are now coming out with a new methodology with ratings being released in April, which actual hospitals agree with be fairer, but the key is the data being used at least a year old and up to three years old. So the data is always old data, from certain aspects of reporting, so improvements take 2-3 years to get the improvements to show up in the data.

Also, CMS only uses Medicare data for the majority of the measures reported, which means not the whole picture at all

So, this is from CoachK's mouth who works with and reports to CMS
