Rosemary Peterson, MD


Rosemary Peterson, MD is a Fellow in the Pediatric Hospital Epidemiology and Outcomes Research Training (PHEOT) program managed by the Center for Pediatric Clinical Effectiveness (CPCE) at The Children’s Hospital of Philadelphia. She is also a fellow in the division of rheumatology at CHOP and a student in the Master of Science in Clinical Epidemiology program at Penn.

Dr. Peterson received her BS in Pre-Professional Science and Psychology from the University of Notre Dame and her MD from the University of Texas Southwestern Medical School. She completed pediatrics residency at Lucile Packard Children’s Hospital at Stanford University, and then joined CHOP for fellowship in pediatric rheumatology. Her research interests are in studying outcomes in systemic juvenile idiopathic arthritis (sJIA), which has particularly high morbidity and mortality compared to other subtypes of JIA. Treatment of sJIA has undergone dramatic changes in recent years with the use of IL-1 and IL-6 inhibition. Yet, there are no existing large epidemiologic studies in the United States examining sJIA outcomes across inpatient and outpatient settings after the advent of these biologic therapies.  There are also no comparative effectiveness studies of IL-1 inhibition compared to IL-6 inhibition although these are currently used interchangeably in clinical practice. Dr. Peterson plans to use large healthcare databases to investigate outcomes of children with sJIA and identify variations in their treatment.
