Archives Of Internal Medicine: Hospital Cost Of Care, Quality Of Care, And Readmission Rates - This study compares patients treated for pneumonia and congestive heart failure (CHF) and finds that high-cost hospitals don't always deliver better care. The researchers, who based their analysis on the data from 3,146 hospitals in the 2004 to 2006 Medicare Provider Analysis and Review (MedPAR), report that "risk-adjusted costs of care for CHF and pneumonia varied widely between hospitals, although hospital cost-of-care patterns seemed stable over time and correlated across conditions."
