Dr. Fitzgerald's research focuses on the impact of pediatric sepsis on renal dysfunction. She examines biomarkers that may be helpful in predicting renal dysfunction in septic acute kidney injury, and the impact of resuscitative therapies and pharmacometrics in sepsis on the development of sepsis-related renal dysfunction.
Bio
Dr. Fitzgerald's research focuses on the impact of pediatric sepsis on renal dysfunction. She examines biomarkers that may be helpful in predicting renal dysfunction in septic acute kidney injury, and the impact of resuscitative therapies and pharmacometrics in sepsis on the development of sepsis-related renal dysfunction.
In collaboration with a multidisciplinary team in the CHOP PICU, she developed and implemented the CHOP PICU severe sepsis pathway in 2012, a set of recommendations for severe sepsis management in the PICU. In 2016, she took on the role of physician lead for Hospital-wide sepsis quality improvement/sepsis governance committee at CHOP.
In parallel with these quality improvement and regulatory efforts, Dr. Fitzgerald has been collaborating in sepsis-related clinical research at CHOP, with a focus on sepsis epidemiology. She and Scott Weiss, MD, MSCE, led an international pediatric severe sepsis epidemiologic study that studied pediatric severe sepsis in 128 pediatric intensive care units in 26 countries and described the prevalence, etiologies, therapies, and outcomes of pediatric severe sepsis. Together with Fran Balamuth, MD, PhD, and Dr. Weiss, she has studied the impact of timely sepsis therapies on outcome in children with sepsis locally at CHOP.

Pediatric septic acute kidney injury: personalizing antibiotic dosing through understanding acute kidney injury risk factors and biomarker profiles.
National Institutes of Health
01/2020 – 12/2024
This study will evaluate urine biomarkers to improve early detection of those at risk for pediatric sepsis-associated acute kidney injury, determine potentially modifiable risk factors related to medication therapies for sepsis that are associated with risk of acute kidney injury progression, use these biomarkers and risk factors to improve pharmacologic models predicting appropriate antibiotic dosing, and test these new pharmacologic models for antibiotic dose adjustments in a pilot trial.

BioPorto Diagnostics, Inc.
3/2022 – 3/2027
This prospective observational clinical study aims to validate the performance of urine NGAL to detect acute kidney injury in critically ill pediatric patients.
