Appendix C: State-Level Bivariate Analysis—State PQI Rates Related to Other Factors, Taken One at a Time

This appendix shows the factors for which State-specific data could be found to compare to the State-specific Prevention Quality Indicators (PQI) included in the 2005 NHQR based on 2001 discharge data from the SID. State-level PQI rates are shown below with whether or not they were correlated with these factors. The results shaded in yellow below denote statistically significant correlations. The direction of the relationship and the percent of variation across States explained by the data element are also shown.

(Bold text denotes statistically significant results.)

Key to Conclusions about Associations Found in Appendix A, Tables 1-3, column 3:

+ = positive association, statistically significant at p<0.05, between QI rates and rates of the other characteristics across the states

- = negative association, statistically significant as explained above

ns = "Not Significant", denotes a statistically insignificant association.

Additional Notations:

** Number of cases reported by States was insufficient to complete analysis

*** Data unavailable for four (4) States; regressions run using remaining 29 States
