• SAS Macro to Compare 2 SIRs February 2014 [SAS – 5K]

  This macro can be used to perform a comparison between two SIRs, consistent with the methods used by NHSN.

• SAS Macro to Compare 2 Incidence Density Rates February 2014 [SAS – 4K]

  This macro can be used to perform a comparison between two incidence density rates (e.g., CAUTI rates), consistent with the methods used by NHSN.
