GECDAC Leadership

Orna Intrator

Orna Intrator, PhD, Director

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.

Ciaran Phibbs

Ciaran S. Phibbs, PhD, Associate Director

Dr. Phibbs is a research economist whose primary research interests include the interaction of hospital competition with costs, demand and outcomes; and perinatal and neonatal care. These interests have led him to study how hospitals and patient characteristics affect the demand for hospital services, and define hospital markets, hospital scale economies and capacity utilization; how Neonatal Intensive Care Units care effects neonatal mortality, the effects of nurse staffing on patient outcomes; the effectiveness of clinical interventions; and the demand for VA services and Veterans’ choice between VA and non-VA services. Dr. Phibbs is also a professor in the Department of Pediatrics – Neonatal and Developmental Medicine at Stanford University.
