Dr. Jim Christenson is an emergency physician at St. Paul’s Hospital and was appointed as Professor and Head of the Academic Department of Emergency Medicine at UBC in September 2010. He is keenly interested in developing a well connected community of emergency physicians across the province and in galvanizing the faculty in the Department to support and facilitate the best care possible in the 101 hospital emergency departments in British Columbia.
From 2005 to 2010 he was the Vice-President, Medical Programs for the Emergency and Health Services Commission (EHSC) and embraced the challenge of optimizing care in the prehospital emergency setting. A keen interest in the best clinical practice during resuscitation motivated involvement in the CPR Guidelines process and extensive volunteer work with the Heart and Stroke Foundation of Canada and the American Heart Association.
Dr. Christenson’s primary research interest is in resuscitation. He is the Principal Investigator for the BC Resuscitation Outcomes Consortium and has been involved in various aspects of cardiac arrest and trauma research for 25 years. The Resuscitation Outcomes Consortium is a network of 10 academic and prehospital/emergency care centers across North America. It is funded by the US National Heart, Lung and Blood Institute, the Canadian Institute for Circulatory and Respiratory Health and the Heart and Stroke Foundation of Canada. The Consortium continues to run clinical trials in promising new therapies in resuscitation and maintain registries in cardiac arrest and major trauma. As a result of an active focus on the quality of resuscitation, the chance of survival in BC from an out-of-hospital cardiac arrest has risen from 6.6% in 2006 to 14.2% in 2011. These improved outcomes mean that every year 150 more British Columbians survive sudden unexpected death than just a few years ago.
Dr. Christenson is committed to further increases in survival through improvements in the pre-hospital resuscitation and post-resuscitation phases of care across BC.
