N2 - Reporting of risk-adjusted surgical outcomes is commonly used to compare providers and track changes over time. Preferred graphical methods use the relationship of the observed to the expected values of outcome events, including their ratio (O/E), and the cumulative sum (CUSUM) of their differences over time, called Risk-Adjusted CUSUM (RA-CUSUM) or Variable Life Adjusted Display (VLAD). We demonstrate these methods using operative mortality data for 7255 isolated coronary artery bypass graft patients from January 2014 to June 2017. RA-CUSUM and VLAD are excellent techniques to display risk-adjusted outcomes and, unlike O/E, can provide continuous monitoring as performance varies over time.
