- SAS Macro to Compare the SIR to 1 February 2014 [SAS - 7 KB]
This macro can be used to calculate the SIR to 1 comparison, consistent with the methods used by NHSN.
- SAS Macro to Compare 2 SIRs February 2014 [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 February 2014 [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 February 2014 [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 February 2014 [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 June 2015 [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.
- Risk Adjustment for Healthcare Facility-Onset C. difficile and MRSA Bacteremia Laboratory-identified Event Reporting in NHSN March 2013 [PDF - 416 KB]
This report describes the risk modeling that CDC applied to LabID event CDI and MRSA bacteremia data submitted to NHSN, the results of which have been incorporated into the analysis options in the NHSN application.
