Public reporting of cardiac surgery performance: Part 2--implementation

Abstract

Appropriate implementation is essential to create a credible public reporting system. Ideally, data should be obtained from an audited clinical data registry, and structure, process, or outcomes metrics may be reported. Composite measures are increasingly used, as are measures of appropriateness, patient satisfaction, functional status, and health-related quality of life. Classification of provider performance should use statistical criteria appropriate to the policy objectives and to the desired balance of sensitivity and specificity. Public reports should use simplified visual or tabular presentation aids that maximize correct interpretation of numerical data. Because of sample size issues, and to emphasize that cardiac surgery requires team-based care, public reporting should generally be focused at the program rather than individual surgeon level. This may also help to mitigate risk aversion, the avoidance of high-risk patients.
