Thomas G Weiser, MD
Assistant Professor of Surgery (General Surgery) at the Stanford University Medical Center
Bio I am a general and trauma surgeon, and surgical intensivist. I treat and care for injured patients and those with acute surgical emergencies, and manage critically ill surgical patients in the Intensive Care Unit.
My research is focused on evaluating the role of surgical care in the delivery of health services in resource poor settings, particularly low and middle income countries. I am interested in barriers to access and provision of surgical care, the quality of surgical services, and outcomes research. My current projects focus on quality and cost effectiveness of care, and strategies for improving the safety and reliability of surgical delivery in resource poor settings. I have been involved in surgical program assessment projects in Cambodia, India, the UK, and the United States. From 2006-2009 I was part of the World Health Organization’s Safe Surgery Saves Lives program where we quantified the global volume of surgery and created, implemented, evaluated, and promoted the WHO Surgical Safety Checklist.
