Hospitals don't even track revision rates (the proportion of the time where a second surgery is required to 'fix' issues from the first), largely because some surgeons cause many problems, and don't want to see the numbers. It's a tragic state of affairs that leads to a great deal of suffering, and I am very pessimistic about the probability of meaningful reform.

They certainly do track it because Medicare will not pay for a second hospital stay in many cases.

Beware of unintended consequences though, hospitals are less inclined to permit riskier surgeries on unhealthy patients if they think the risk of readmissions is too high. Good luck getting your knee replacement if you are a 300lb diabetic smoker.
