Gewertz & Cohen Lab
The Gewertz and Cohen Laboratory, directed by Bruce Gewertz, MD, and Tara Cohen, PhD, seeks to understand the relationships among task, team, technology and environment to create a patient- and practitioner-centered healthcare system that delivers high-quality, safe care at affordable cost. Our research takes a multidisciplinary approach to in-depth understanding of the current challenges faced in delivering trauma and surgical care and pursues improvements through enhancing the integration of technology and teamwork. The Gewertz and Cohen Lab also leverages expertise from a range of experts and industries to translate quality and safety lessons into improved surgical outcomes.
The Gewertz and Cohen Lab has ongoing collaborations with Embry-Riddle Aeronautical University, Daytona Beach; Medical University of South Carolina, Charleston; University of Washington, Seattle; University of Wisconsin-Madison; University of Central Florida, Orlando; Madigan Army Medical Center, Joint Base Lewis-McChord, Washington, The Stephenson Foundation, Menlo Park, California and leading synergistic companies. These collaborations enable the Gewertz and Cohen Laboratory to pool international expertise for the benefit of our partners within Cedars-Sinai and deliver innovative, high-quality research to ensure that our findings can be used immediately to enhance patient care.
To further the expansion of our research, Cedars-Sinai has designed and built an experimental simulation space that features flexible moving walls, equipment on movable ceiling tracks that pivot around surgical teams, a range of realistic equipment, and a state-of-the-art control room and video data collection system. Conference suites and debriefing rooms are also housed in the research space. The architectural design is designed to foster creative solutions to complex surgical-care logistical challenges and to offer a unique space for experimenting with and reconfiguring the interactions among teams, workspaces and equipment for 21st-century care.
The Gewertz and Cohen Laboratory is affiliated with the Cedars-Sinai Surgery Department.
Bruce L. Gewertz, MD, is Surgeon-in-Chief, Chair of the Department of Surgery, Vice Dean for Academic Affairs and Vice President for Interventional Services. He was educated at Pennsylvania State University and Jefferson Medical College, now the Sidney Kimmel Medical College, in the combined BS/MD five-year program.
