HOW GOOD ARE
In December 2012, federal health officials redistributed an estimated $964 million in Medicare payments to hospitals based on the quality of care patients received — it's effectively a pay-for-performance program.
The amount of money isn't huge — it's roughly 1 percent of total Medicare payments — but the index used to calculate the financial bonuses and penalties does provide one clear measurement of hospital quality.
How did officials measure quality? Two ways: "Measures of timely and effective medical care" and surveys of patients' hospital experience. The two sets of measurements are weighted and combined in a 100-point index.
