Relationship Between Provider Experience and Cardiac Performance Measures in Outpatients (from the NCDR)

Compliance with cardiac performance measures for guideline-directed medical therapy remains suboptimal. There is a compelling need to identify modifiable factors that influence compliance rates, so that these factors can be addressed as targets of quality improvement. This study examines the relationship between cardiovascular provider experience and compliance with performance measures for outpatients with coronary artery disease (CAD), heart failure, and atrial fibrillation in the PINNACLE Registry. We hypothesize that providers who have been practicing longer, especially those further out from certification who may not be required to recertify, will have lower compliance rates with key cardiac performance measures. Using clinical data from January 1, 2013 to March 31, 2014 in the PINNACLE Registry, we employed a multilevel hierarchical logistic regression analysis to examine the relationship between cardiac performance measures and provider experience, defined by the number of years since initial cardiology board certification (<10 years vs 10 to 20 years vs ≥20 years). We found a significant difference in compliance in 4 out of 9 outpatient cardiac performance measures between providers with different experience levels. Providers with ≥20 years since certification were less compliant with 3 out of the 4 statistically different performance metrics; however, the absolute difference between performance measures by provider experience level was small. In conclusion, performance on several key cardiovascular quality measures demonstrate a statistically significant negative association with physician experience-level defined by years since initial cardiology certification, but the clinical significance of this finding is unclear.
