User Guide and Technical Specification

The User Guide and Technical Specification provide direction on the rationale of the Prevention Quality Indicators (PQIs). 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 PQI. 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 PQIs.  One group is based on age and sex exclusively, and the other is based on age, sex and the socioeconomic decile of each county.  The two versions correspond to the two selections you may make within the QI software.  (SAS Control file, WinQI Report Options)
