Dr. Chiotos is a graduate of the College of William and Mary and the George Washington University School of Medicine, and recently earned a Master’s of Science in Clinical Epidemiology from the University of Pennsylvania. She completed pediatrics residency training at Children’s Hospital of Philadelphia (CHOP), followed by a combined fellowship in pediatric infectious diseases and pediatric critical care medicine.
Dr. Chiotos joined the faculty at the University of Pennsylvania in 2017 and is currently an Assistant Professor of Anesthesia, Critical Care, and Pediatrics with a secondary appointment in pediatric infectious diseases.
Dr. Chiotos’ research focuses on the epidemiology of antibiotic resistant organisms in the pediatric intensive care unit setting as well as antibiotic stewardship in this population. She is involved with several quality improvement initiatives surrounding optimizing antibiotic use and diagnostic evaluation for patients with suspected sepsis at CHOP.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
