Table displays pairwise correlations of 10 quality measures across the 306 HRRs. PQI composites and 30‐day readmissions are adjusted for age, sex, age/sex interaction, and health status. Each measure was coded such that a higher score was associated with better performance for each of the indicators (high scores for readmissions and PQIs represent good quality.) Bonferroni correction adjusted for multiple comparisons for the 45 pairwise comparisons (individual tests at α = .001).
DMARDs, disease‐modifying antirheumatic drugs; PQIs, prevention quality indicators.
