Orna Intrator

Orna Intrator, Director of the Geriatrics and Extended Care Data and Analysis Center

Dr. Intrator is a long-term care researcher at the Canandaigua VA Medical Center and the University of Rochester. Trained in statistics and applied mathematics, one of the foci of Dr. Intrator’s VA research is Veteran’s use of nursing homes across health care systems and the quality of care delivered, with particular attention to the implications for health policies and organizational management. Dr. Intrator and her team developed the VA Residential History File (RHF) which pulls together claims and assessment data from VA, Medicare and Medicaid enrollment, claims, utilization and assessments, as well as other data sets. These data sets are then standardized and organized along a timeline to facilitate analyses.  Dr. Intrator is currently examining the system-wide impact of provision of geriatrics and extended care services.
