Sepsis Alliance Symposium: Precision Sepsis Care (Enduring Course)

Steven Q. Simpson, MD is Professor of Medicine at the University of Kansas in the Division of Pulmonary, Critical Care, and Sleep Medicine, where he previously served as Division Director, Director of three ICUs, Chair of the Sepsis Team, and Chair of Multidisciplinary Critical Care. He has done research in all areas of severe sepsis from molecular and cellular mechanisms, to translational studies, to quality improvement studies. He was a founder, in 2005, of the Midwest Critical Care Collaborative, a multidisciplinary and interprofessional collaborative effort to improve the quality of critical care services throughout the Midwest. In 2007, he initiated the Kansas Sepsis Project, a statewide program to improve severe sepsis care and outcomes throughout the state via continuing education both in sepsis and in quality improvement principles, and via inter-professional collaboration. He is currently heading a BCBS-sponsored sepsis collaborative among Kansas City metro area hospitals and is a contributing faculty member of the ongoing Surviving Sepsis Campaign collaboratives, leading the effort in the Midwest. He is a participant in the 2016 review and update of the Surviving Sepsis Campaign Guidelines. Dr. Simpson was the North American co-chair of the International Single Day Point Prevalence Study for Severe Sepsis and Septic Shock (IMPRESS) in the fall of 2013. During his tenure at the University of New Mexico, he contributed to the discovery of a particular form of sepsis, the Hantavirus Pulmonary Syndrome, and published numerous papers on the clinical description, the hemodynamic description, and the approach to supportive care for patients with the syndrome, including extracorporeal hemodynamic and oxygenation support. Dr. Simpson received his M.D. degree from the University of Kansas in 1983. He completed residency training in Internal Medicine at KU in 1986 and fellowship training in Pulmonary Diseases at Rush Medical College in 1989. He has been a faculty member at Rush Medical College, the University of New Mexico, and the University of Kansas. He is a regular reviewer for the journals Critical Care Medicine and CHEST, and he reviews on an ad hoc basis for Shock, the Journal of Intensive Care, JAMA, Virology, and Antiviral Therapy. He is the author of over 70 peer reviewed and invited manuscripts, book chapters, and web-based articles and presentations. Dr. Simpson was the Third Eli Lilly and Company Distinguished Scholar in Critical Care Medicine, sponsored by the American College of Chest Physicians and the Chest Foundation for his work in reducing geographic disparities for severe sepsis care (the Kansas Sepsis Project). In 2013 he delivered the Roger C. Bone Memorial Lecture at the annual international meeting of the American College of Chest Physicians, describing the Kansas Sepsis Project. Dr. Bone was Dr. Simpson’s early career mentor and was the progenitor of the criteria used throughout the world to recognize severe sepsis.

Richard Hotchkiss, MD, studied at the University of Virginia where he received both his undergraduate and medical degrees and was inducted into the Phi Beta Kappa and Alpha Omega Alpha Honor Societies. He trained in two specialties, first in Internal Medicine at Emory University School of Medicine (where he was also Chief Resident), and then in Anesthesia at the Massachusetts General Hospital. Dr. Hotchkiss pursued his interest in critical care as a Fellow at the University of Virginia and then as a Senior Fellow in the Respiratory Intensive Care Unit. In 1987, Dr. Hotchkiss moved to the Department of Anesthesiology at Washington University in St. Louis where he has remained, climbing the ranks to Professor in the Departments of Anesthesiology, Medicine, Surgery, and Molecular Biology & Pharmacology. Dr. Hotchkiss has had a long, successful career as an investigator studying the pathophysiology of sepsis. His many contributions are documented in over 200 publications. A seminal observation from his laboratory was the identification of extensive apoptotic death of immune effector cells in patients dying of sepsis. This discovery led to the concept that apoptosis-induced immunosuppression is an important pathogenic mechanism in sepsis, a finding that has changed the paradigm in search of new therapeutic approaches to this major threat to public health. A review article on sepsis by Drs. Hotchkiss and Irene Karl helped define and promulgate this concept and is now the sixth most cited review article in the New England Journal of Medicine in the last decade. Dr. Hotchkiss has been continuously funded by the National Institutes of Health for approximately 20 years and is the recipient of a number of prestigious awards, including the NIH Research Career Development Award (1995) and the NIGMS Merit Award (2003). Additional honors include serving as President of the Shock Society for which he received the Distinguished Service Award of the Society in 2007. Washington University in St. Louis honored him with its Distinguished Investigator Award in 2008.

Tim Sweeney, MD, PhD, helped invent the core Inflammatix technology and is a licensed physician and data scientist. He completed his MD/PhD at Duke University and then spent time training in the general surgery residency program at Stanford University. While training as a surgeon, he became frustrated with the current diagnostic tools for infection. During his residency research years, he completed a postdoc MS in Biomedical Informatics, during which he worked with Dr. Khatri to identify a new way to diagnose infections based on ‘reading’ the immune system. Their work designing custom informatics algorithms for sifting through heterogeneous large datasets led to the core technology on which Inflammatix is based.
