User Guide and Technical Specification

The User Guide and Technical Specification provide direction on the rationale of the Inpatient Quality Indicators (IQIs). It also provides an overview of the methods used to identify, select, and evaluate the Agency for Healthcare Research and Quality (AHRQ) Quality Indicators (QIs), a summary of the literature based evidence, empirical rates based on the State Inpatient Databases, and detailed definitions for each IQI. Potential users of this document include hospitals, State data organizations, and hospital associations.

Covariates Used in Risk Adjustment

Two sets of covariates are  provided for the IQIs.  One group is based on a reference population that includes "Present on Admission" data (new in v3.1), and the other does not.  The two versions correspond to the two selections you may make within the QI software.  (SAS Control file, WinQI is determined automatically based on the loaded data.)
