Institution: University of Virginia School of Medicine
Grant Title: Mortality
Risk Adjustment Using Hospital Claims Data
Grant Number: K02 HS011419
Total Award: $198,300
Project Description: This research had four
- Develop improved public domain mortality risk adjustment
models for use with administrative data.
- Rigorously validate the developed
models in independent data sets.
- Compare the new model's statistical
performance to that of existing alternatives.
- Provide Internet-based
public access to the developed risk adjustment models.
Career Goals: Dr. Stukenborg is an
Assistant Professor in the Department of Health Evaluation Sciences at the
University of Virginia School of Medicine in Charlottesville. He received his
Ph.D. in Health Services Research at the Virginia Commonwealth University in Richmond. His expertise lies in the analysis of population-based data
Progress to Date: This grant has been
completed. The research activities supported by this award demonstrate that
mortality risk adjustment methods can be meaningfully improved by using
present-at-admission diagnoses to identify comorbid disease. Models using
present-at-admission diagnoses obtain better discrimination between predicted
survival and in-patient death, better calibration across ranges of higher
mortality risk, and explain more of the observed variation in mortality risk
than the other models considered during the research.
