Silver Book Fact
Risk-adjusted mortality ratios in hospitals
Based on 2000-2002 mortality rates for Medicare beneficiaries, there is a 33-percentage point spread between the risk-adjusted mortality ratios achieved in the best 10% of hospitals and the bottom 10%. If hospitals with mortality rates that are higher than expected brought deaths down to levels that were expected given their patient mix, the improvement would save approximately 17,000-21,000 lives per year.
