Current Version

The AHRQ Quality Indicators software has been updated to Version 3.2. 

AHRQ Quality Indicators Software

The Agency for Healthcare Research and Quality (AHRQ) provides free software for organizations to apply the AHRQ Quality Indicators (QIs) to their own data to assist quality improvement efforts in acute care hospital settings. 

  • The  QI SAS Software must be run in the SAS® statistical software package that must be obtained separately.  It is often preferred by researchers who have millions of records and want to write programs that use the statistical capabilities available in SAS.
  • The QI Windows Software has a graphical user interface and is often preferred by non-programmers.  It requires SQL Server®, a free version of which may be downloaded from this page. 

Both versions include all of the AHRQ QI modules: Prevention Quality Indicators, Patient Safety Indicators, Inpatient Quality Indicators , and the Pediatric Quality Indicators Both versions are able to compute observed rates for all indicators and both versions allow the comparison of observed rates to expected rates that are specific to each population and case mix.  

QI SAS Software

The QI SAS modules are programs that run in the SAS® statistical software package. To use these modules, users must have access to SAS® which may be purchased from The SAS Institute.

All necessary components for running the software are included in the zip file, but users must provide a hospital discharge data file in the specified format. The software documentation describes the procedures for implementing the AHRQ QIs and highlights features of the analytic approach of particular interest to users. The documentation and user guide are not included in the software zip file and should be downloaded separately.

The population files are now a separate download and may be used with the PSI, IQI, PDI and PQI modules for Area-level indicators.

QI Windows Software

The QI Windows Application is easy to use with step-by-step instructions on loading your data and verifying that the data is in the format required.  Users can look at the results for individual cases, the organization as a whole, or for subgroups based on patient demographics.

  • Microsoft Windows 2000 or Windows XP
  • Microsoft .NET Framework ®  (Included)
