Key result
Publication of performance data and voluntary quality improvement initiatives were associated with 41% and 24% decreases in risk-adjusted CABG mortality rates between 1987 and 1993, respectively.
Large-scale interventions such as public reporting of performance data and voluntary quality improvement consortiums have been associated with significant reductions in CABG mortality.
The burgeoning outcomes measurement industry has generated growing attention to steps that governments and organizations can take to promote better outcomes. In an era of growing belief in market forces and disquiet with regulation, publishing information for consumers and providing technical assistance to providers have special appeal. A leader in the former has been New York State, which has published statewide information on mortality rates of coronary artery bypass graft (CABG) centers and surgeons. Three years ago, Hannan and colleagues¹reported that publication of performance had been followed by a 41% decrease in risk-adjusted CABG mortality rates in New York between 1987 and 1993. They argued that publication played a significant role in the decline. Last year, O'Connor and colleagues²reported a 24% decrease in risk-adjusted mortality between 1987 and 1993 in the Northern New England Cardiovascular Disease Study Group, which is a voluntary quality improvement consortium of

Stephen F. Jencks (1997) conducted an editorial in Coronary artery bypass graft (CABG). Publication of performance data was evaluated on Risk-adjusted CABG mortality rates. Publication of performance data and voluntary quality improvement initiatives were associated with 41% and 24% decreases in risk-adjusted CABG mortality rates between 1987 and 1993, respectively.
