About Spine Sage

The SpineSage tool is a predictive model based on data from the Spine End Results Registry. The Spine End Results Registry is a prospectively collected data registry for all patients undergoing spine surgery at Harborview Medical Center and University of Washington Medical Center from January 1st 2003, to December 31st, 2004. Extensive co-morbidity and demographic data were defined a priori and collected prospectively for each surgical patient. Complications were defined a priori and were prospectively recorded for at least 2 years following the surgery.

Several multivariate log-binomial analyses were performed to identify and quantif risk factors for these complications after spine surgery and have been published in the peer-refereed literature. Based on these analyses, predictive models for these complications were devised and are the focus of SpineSage.
