• A Guide to Using the NHSN Macros May 2021 [PDF – 537 KB]
  This document describes the macros that are used in NHSN, and provides guidance and examples on how to run them in SAS and interpret the results.

NHSN Macros

• SAS Macro to Compare the SIR to 1 or Other Nominal Value May 2021 [SAS – 5 KB]
  This macro can be used to compare the SIR to a single nominal value, consistent with the methods used by NHSN.
• SAS Macro to Compare 2 SIRs May 2021 [SAS – 5 KB]
  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 May 2021 [SAS – 5 KB]
  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.
• SAS Macro to Compare 2 Proportions May 2021 [SAS – 6 KB]
  This macro can be used to perform a comparison between two proportions (e.g., catheter device utilization ratios), consistent with the methods used by NHSN.
• SAS Macro for a Single Incidence Density Rate May 2021 [SAS – 3 KB]
  This macro can be used to perform confidence interval testing around a single incidence density rate (e.g., CLABSI rate), consistent with methods used by NHSN.
• SAS Macro for a Single Proportion May 2021 [SAS – 3 KB]
  This macro can be used to perform confidence interval testing around a single proportion (e.g., healthcare worker flu vaccination percentages). This macro can also be used to compare a single proportion to a benchmark value, consistent with methods used by NHSN.
