The following are the standardized infection ratios — observed to expected infection rates — for surgical site infections after abdominal hysterectomy for every state and Washington, D.C.
SIRs that are less than one indicate the state had fewer SSIs after hysterectomy than would have been predicted. SIRs greater than one indicate infection rates were higher than would be predicted.
For SIRs less than one, subtracting the SIR from one shows the percent decrease in SSIs from the baseline (an SIR of 0.80 means there was a 20 percent reduction from baseline). For SIRs greater than one, subtracting one from the SIR shows the percent increase (an SIR of 1.35 means there was a 35 percent increase from baseline).
Here, states are listed from smallest to largest SIR, or from the states with the lowest infection rates to the highest infection rates as compared with expected infection rates.
Note: States' SIRs show their individual progress in reducing SSIs after abdominal hysterectomy and are not meant to compare actual SSI rates among states. Data was updated April 16 and comes from CMS' Hospital Compare database.
