from the Wall Street Journal ObamaCare’s Failed Cost Controls:

ObamaCare also included a provision to penalize hospitals that have high rates of readmission within 30 days. This was supposed to cut costs, and hospitals have reduced readmissions. But new data shows that mortality rates have also increased, suggesting the policy may contribute each year to 5,400 premature deaths of Medicare patients with serious heart conditions. This is another instance of the unintended consequences when government meddles in the practice of medicine. Moreover, there is no evidence that the policy has reduced overall costs, because hospitals can provide other services to make up for lower readmissions.
