Coronary Artery Bypass Graft: Hospital Performance Ratings, 2023
119 state-licensed hospitals performed adult CABG surgery during 2022-2023. The statewide isolated CABG mortality rate for 2023 was 2.0%. This was a decrease from the 2022 mortality rate of 2.5%, and represents a 30.3% decrease since 2003, the first year of mandated reporting.
Coronary Artery Bypass Graft (CABG) surgery outcomes reports are based on data collected by the Department of Health Care Access and Information (HCAI) California Cardiovascular Outcomes Reporting Program (CCORP). The reports and visualizations provide quality ratings for the state-licensed hospitals that perform coronary artery bypass graft surgery. During 2022-2023, 119 state-licensed hospitals performed adult CABG surgery.
The performance ratings are based on four key risk-adjusted outcomes: operative mortality for isolated CABG, operative mortality for CABG + Valve, post-operative stroke, and isolated CABG 30-day readmission.
Key Findings
- The statewide isolated CABG mortality rate for 2023 was 2.0%. This was a decrease from the 2022 mortality rate of 2.5%, and represents a 30.3% decrease since 2003, the first year of mandated reporting.
- The operative mortality rate for CABG + Valve surgery in California was 5.4% in 2022-2023. This rate was lower than the 2021-2022 rate of 5.7%.
- The post-operative stroke rate for isolated CABG surgery in California was 1.4% in 2022-2023. This rate was lower than the post-operative stroke rate from 2021-2022 of 1.5%.
- The statewide hospital all-cause unplanned 30-day readmission rate was 11.2% for those who underwent isolated CABG surgery in 2022-2023. This rate was lower than the 2021-2022 rate of 11.3%.
- There is no consensus on an optimal usage rate for internal mammary artery (IMA), so performance ratings are not given. The IMA average usage rate for all hospitals was 99.3% in 2023, 99.4% in 2022, and 89.6% in 2003.
