TITLE: The Monitoring of Surgical Outcome Quality


Some statistical issues related to the monitoring of surgical outcome quality will be reviewed in this presentation. The important role of risk-adjustment in healthcare, used to account for variations in the health conditions of patients, will be described. Several of the methods for monitoring outcome quality over time, including a new one, will be outlined and illustrated with examples. The advantages of using the conditional false alarm rate metric will be emphasized.
