ABSTRACT
BACKGROUND: Little is known about the procedural characteristics, case volumes, and mortality rates for early- vs non-early-career interventional cardiologists in the United States.
OBJECTIVES: This study examined operator-level data for patients who underwent percutaneous coronary intervention (PCI) between April 2018 and June 2022.
METHODS: Data were collected from the National Cardiovascular Data Registry CathPCI Registry, American Board of Internal Medicine certification database, and National Plan and Provider Enumeration System database. Early-career operators were within 5 years of the end of training. Annual case volume, expected mortality and bleeding risk, and observed/predicted mortality and bleeding outcomes were evaluated.
RESULTS: A total of 1,451 operators were early career; 1,011 changed their career status during the study; and 6,251 were non-early career. Overall, 514,540 patients were treated by early-career and 2,296,576 patients by non-early-career operators. The median annual case volume per operator was 59 (Q1-Q3: 31-97) for early-career and 57 (Q1-Q3: 28-100) for non-early-career operators. Early-career operators were more likely to treat patients presenting with ST-segment elevation myocardial infarction and urgent indications for PCI (both P < 0.001). The median predicted mortality risk was 2.0% (Q1-Q3: 1.5%-2.7%) for early-career and 1.8% (Q1-Q3: 1.2%-2.4%) for non-early-career operators. The median predicted bleeding risk was 4.9% (Q1-Q3: 4.2%-5.7%) for early-career and 4.4% (Q1-Q3: 3.7%-5.3%) for non-early-career operators. After adjustment, an increased risk of mortality (OR: 1.08; 95% CI: 1.05-1.17; P < 0.0001) and bleeding (OR: 1.08; 95% CI: 1.05-1.12; P < 0.0001) were associated with early-career status.
CONCLUSIONS: Early-career operators are caring for patients with more acute presentations and higher predicted risk of mortality and bleeding compared with more experienced colleagues, with modestly worse outcomes. These data should inform institutional practices to support the development of early-career proceduralists.
