Biographical Information
Scott A. Lorch, MD, MSCE, is Associate Professor of Pediatrics at the University of Pennsylvania Perelman School of Medicine. He is an Attending Neonatologist and Director of the Neonatal-Perinatal Fellowship Training Program at the Children’s Hospital of Philadelphia. Dr. Lorch earned both his Bachelor of Arts in Political Science and his Medical Degree from Northwestern University in 1992 and 1996 respectively. He received his Master of Science degree in Clinical Epidemiology (MSCE) from the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania in 2003. He is Deputy Director of the Center for Outcomes Research and is centrally involved with research projects concerning racial disparities, perinatal epidemiology, health economics, and quality of care in both adult and pediatric settings. 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.
Dr. Lorch is currently the principal investigator on several federally funded projects. These projects include "Parental Trust and Racial Disparities in the Care of Discharged Premature Infants," funded by the National Institute of Child Health and Human Development, a study entitled "Impact of Obstetric Unit Closures on Pregnancy Outcomes," funded by the Agency for Healthcare Research and Quality, and a study funded by the Health Resources and Services Administration entitled "Evaluating Maternal and Neonatal Outcomes in the Provision of Obstetric Care." Dr. Lorch is also an investigator for the national Pediatric Quality Measures Program (PQMP), leading a study of the influence of various enrollment eligibility requirements on changing the assessed quality of states using the first 23 core quality measures for pediatric care published by the Agency for Healthcare Research and Quality (AHRQ).
Dr. Lorch received the Best Abstract, Child Health Call for Papers award at the AcademyHealth Annual Meeting in 2012 and the Young Investigator Award at the Perinatal Research Society Meeting in 2003. He routinely receives faculty teaching awards from the Division of Neonatal-Perinatal Medicine and honors associated with the Neonatal-Perinatal Fellowship Training Program.
