Covariates Used in Risk Adjustment

Two sets of covariates are  provided for the PSIs.  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.)
