Scott A. Lorch, MD, is an attending neonatologist and Associate Chief of the Division of Neonatology at Children's Hospital of Philadelphia. He holds the Harriet and Ronald Lassin Endowed Chair in Pediatric Neonatology.
Scott A. Lorch, MD, MSCE, is a professor of pediatrics at the Perelman School of Medicine at the University of Pennsylvania. He also serves as Associate Chief and Director of Clinical and Epidemiological research of the Division of Neonatology.
Dr. Lorch received an MD from Northwestern University and a Master of Science degree in Clinical Epidemiology (MSCE) from the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania. His overarching research goal to understand the root causes for variations in health outcomes and health care utilization experienced by high-risk children, particularly those born prematurely.
He has extensive expertise in three key components: (1) quality of care assessment; (2) racial/ethnic and socioeconomic disparities of care; and (3) the role of health care organization on the outcomes of ill children. These topic areas have served as the primary areas for mentorship of 3 pre-doctorial trainees and 28 post-doctoral fellows, with over 50 publications performed by these trainees. He also has extensive experience with population-based data and the development and analysis of large patient cohorts along with expertise in the statistical methodologies such as causal inference techniques and mediation analysis.
Dr. Lorch has been an investigator on 11 federally funded projects, with current projects focusing on Access to high-quality hospital and racial/ethnic disparities in perinatal outcomes; obstetric and neonatal intensive care volume-outcome relationships; risk assessment and targeted interventions for postpartum mothers; and the role of COVID on perinatal health care use and outcomes.

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.
