Insights

Racial disparities in coronary artery bypass graft surgery (CABG) care have declined. While access to high-quality surgeons improved for Black patients, gaps in overall surgical access persist.

Area of Science:

  • Cardiovascular Surgery
  • Health Disparities Research
  • Health Services Research

Background:

  • Persistent racial disparities exist in US medical care, particularly for African American patients.
  • Minority patients have lower utilization rates for coronary artery bypass graft surgery (CABG).
  • Black patients often receive care from surgeons with poorer performance records compared to white patients.

Purpose of the Study:

  • To examine the persistence of disparities in CABG care, including surgical access and access to high-quality surgeons.
  • To investigate potential causes for the observed decline in these disparities in recent years.

Main Methods:

  • Retrospective analysis of Medicare inpatient and physician claims and New York State Cardiac Surgery Reports.
  • Comparison of CABG access and surgeon quality for white and Black patients between two periods: 1997-1999 and 2001-2003.
  • Measurement of patient numbers by race and surgeon quality using risk-adjusted mortality rates.

Main Results:

  • Disparities in CABG care between white and Black patients have declined between the late 1990s and early 2000s.
  • The decline in disparities appears linked to increased surgical capacity among all surgeons.
  • Gaps in overall access to CABG surgery between racial groups still remain.

Conclusions:

  • While disparities in CABG care have decreased, they have not been entirely eliminated.
  • Increased surgical capacity may have contributed to reduced disparities in accessing high-quality surgeons.
  • Further efforts are needed to address remaining barriers to equitable access to CABG surgery.
