Scott A. Lorch, MD, MSCE, is a professor of pediatrics at the Perelman School of Medicine at the University of Pennsylvania and the Director for the Center for Clinical Epidemiology and Biostatistics. He also serves as Associate Chief of the Division of Neonatology.
Dr. Lorch received his Master of Science degree in Clinical Epidemiology (MSCE) from the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania and has been a faculty investigator at the Center for Outcomes Research centrally involved with projects concerning health economics and quality of care research in both adult and pediatric settings.
Dr. Lorch is the director of the Center for Perinatal and Pediatric Health Disparities Research and is the principal investigator on four federally funded projects. Currently he is the principal investigator of a study entitled Parental Trust and Racial Disparities in the Care of Discharged Premature Infants, funded by the National Institute of Child Health and Human Development (Grant Number 1R01HD57168); a study entitled Aggregated Complication Measure for Neonatal Quality of Care funded by the Maternal and Child Health Bureau (Grant Number R40MC05474), a three-year study funded by the Agency for Healthcare Research and Quality entitled Perinatal Regionalization and Quality of Care (Grant Number 1R01HS015696-01A2); and a four-year study funded by the Agency for Healthcare Research and Quality entitled Impact of Obstetric Unit Closures on Pregnancy Outcomes (R018661).
Dr. Lorch is also an investigator in the Pediatric Quality Metric Consortium site at The Children's Hospital of Philadelphia. He was worked with Pennsylvania and New York pediatric discharge data to examine the effects of hospital occupancy on the efficiency of pediatric hospital care, and the difference between urban and rural hospitals in terms of treatment of children. These outcomes studies were conducted at the Center for Outcomes Research, working with the COR research staff.
His work has investigated various measures of infant quality of care and analyses of systems for delivering neonatal care, specifically using an instrumental variables approach and other methods to reduce systematic biases in these types of studies.

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.
