Brendan G. Carr, MD, MA, MS is a Professor of Emergency Medicine, Vice Chair for Healthcare Policy in the Department of Emergency Medicine, and Associate Dean for Healthcare Delivery Innovation at Sidney Kimmel Medical College at Thomas Jefferson University. He completed residency in emergency medicine and a fellowship in trauma & surgical critical care at the University of Pennsylvania. Following clinical training Dr. Carr entered the Robert Wood Johnson Foundation's Clinical Scholars Program where he received formal training in research methods and a Master of Science Degree in Health Policy Research. In addition to faculty and clinical responsibilities, Dr. Carr is also the Director of the Emergency Care Coordination Center at the US Department of Health and Human Services.

Dr. Carr has written over 100 peer reviewed manuscripts, serves as a reviewer for over a dozen peer-reviewed journals, and as an editor for Annals of Emergency Medicine. His research focuses on understanding how the organization of emergency care impacts outcomes in unplanned critical illness. He has studied outcomes and delivery systems for trauma, stroke, cardiac arrest, and sepsis. His most recent work focuses on the underlying drivers of variability in health outcomes and developing novel approaches to align incentives in order to improve population health.

Research Projects

Dr. Carr’s core work focuses on understanding the underlying drivers of variability in health outcomes and developing novel approaches to align incentives in order to improve health. Current large-scale projects focus on utilizing patient-level claims data to study outcomes for emergency care sensitive conditions including trauma, sepsis, and out-of-hospital cardiac arrest. The Population Science Research (PSR) group, led by Dr. Carr, is developing attribution methods that can be used to develop population-based quality measures and incentive structures. PSR also studies interventions that can leverage expertise within a region to improve the coordination of healthcare delivery, and policy levers that could improve alignment between health system priorities and community needs. Dr. Carr and his research group use traditional quantitative health services research methods including regression and hierarchical modeling, as well as geospatial clustering approaches and machine and deep learning methods to generate a novel understanding of how changes in care delivery can impact changes in outcomes.

Geography of Acute Care

This work is a 5-year study (9/2014 – 9/2019) funded by the Agency for Healthcare Research and Quality. The overarching goal of this study is to empirically derive novel healthcare coalitions and the corresponding catchment areas that can be used to describe and incentivize the achievement of population health.

A Population-Based Approach to Improve Outcomes after Out-of-Hospital Cardiac Arrest

This work is a 5-year study (4/2018 – 1/2023) funded by the National Heart, Lung, and Blood Institute. This project uses state-of-the art spatial methods to define the geographic boundaries of Out-of-Hospital-Cardiac-Arrest (OHCA) service areas and to then benchmark system performance across communities for the entire US. Our methods define the community based on where patients with OHCA live and receive their care. The long-term goal of this project is to empower communities to hold the public health and health systems that serve them accountable for the health of the population.
