This third report from the California CABG Mortality Reporting Program (CCMRP) presents findings from analyses of data collected from 77 of California's 121 hospitals that regularly performed CABG surgery and uses in-hospital mortality as the key outcome measure.

This third and final report provides a comprehensive description of the program, including the methodologies used, the risk model, and detailed statistical results and data summaries for the 77 participating hospitals.

The 2000-2002 report tracks 73 percent of coronary artery bypass surgeries performed in California’s hospitals and confirms findings from previous reports - volunteer hospitals are the better performing hospitals and hospitals with a higher volume of surgeries (greater than 200 per year) tend to have better outcomes.

The results indicate that although not all low volume hospitals have poor performance, there is a clear relationship between high volume and lower mortality.
