Some statistical issues related to the monitoring of surgical quality will be reviewed in this presentation. The important role of risk-adjustment in healthcare, used to account for variations in the condition of patients, will be described. Some of the methods for monitoring surgical outcomes over time will be outlined and illustrated with examples. A new on-line method for designing the most frequently recommended method, the risk-adjusted Bernoulli cumulative sum chart, will be explained. The National Surgical Quality Improvement Program (NSQIP) will be described, along with a case study demonstrating significant improvements in surgical infection rates and mortality.
