On March 28, the Southern California Chapter held its 27th annual Workshop in Applied Statistics. Arlene Ash, research professor of medicine and public health at Boston University School of Medicine, gave an informative seminar, titled "The Vital Importance of Adjusting for Patient Risk: Risk Adjustment in Health Services Research." The workshop provided an introduction to the major conceptual, practical, technical, and policy issues related to risk adjustment in health services research. Specific topics covered included the need for risk adjustment, the major dimensions of risk, the strengths and limitations of different data sources for risk adjustment, the use of multivariable models for risk adjustment, and performance measures for risk adjustment models, as well as the use of propensity scores and instrumental variables as enhancements to standard modeling.
