Authors' conclusion

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.

Study context

Population
Patients undergoing Percutaneous Coronary Intervention (PCI) in the US (NCDR CathPCI Registry), April 2018–June 20221,011 operators changed status
Participants
1,451 vs 6,251
Exposure
Early-career vs non-early-career interventional cardiologists
  • Early careern = 1,451
  • Non-early careern = 6,251reference
