A smaller SIR denotes better performance
*Estimated using total number of U.S. MRSA Bloodstream Infections and total number of U.S. Hospital Patient Days
**Negative values increases performance with a smaller SIR, postive values decreases performance with a larger SIR
Non-Risk Adjusted SIR was calculated using a ratio of the hospital’s observed cases / the hospital’s Non-Risk Adjusted Perdicted Cases
Non-Risk Adjusted Perdicted Cases was calucated by multiplying the Non-Risk Adjusted National Infection Rate by the number of facility Patient Days
Non-Risk Adjusted National Infection Rate equals the the sum of the national total Observed Cases divided by the national total number of Patient Days
N equaled 3917 U.S. facilities
