The overarching goal of the Brigham and Women’s Hospital Emergency Medicine/Critical Care Fellowship program is to train the next generation of clinician-scientists through provision of extensive and intensive clinical training. Graduates of the program will be skilled in the cognitive knowledge, procedural, interpersonal skills, professional attitudes, and practical experience required to practice critical care medicine. We aim to graduate trainees that will have the clinical and research skills that will allow them to ultimately advance the practice of emergency medicine and critical care medicine as well as novel areas of scientific inquiry that will improve outcomes for all of our patients.

The curriculum includes the required 24 months of clinical training. This training period includes at least sixteen months of meaningful patient care with responsibility for inpatients with a wide range of medical and surgical diseases, with an educational emphasis on multi-system physiology and its correlation with clinical disorders. The training also includes at least twelve months of clinical training in critical care medicine, of which six months are devoted to the care of critically ill medical ICU patients, and six months are devoted to the care of critically-ill non-medical patients. There are no more than 12 months of required ICU experience in the 2-year training period.

Our curriculum is outlined below with detailed competency-based goals and includes. The critical care rotations include the BWH MICU (tertiary referral center ICU), the VA MICU (which will allow increased fellow responsibility for leading the care plan). Non-medical critical care rotations will include the BWH surgical ICU (including post-operative care, burns, neurosurgical, cardiovascular, and trauma), the BWH thoracic ICU (including post-operative care for thoracic patients and in depth training in procedures including airway management, chest tube insertion and management, and exposure to percutaneous tracheostomies), and the BWH Surgical Cardiovascular ICU and Neurosurgical ICU.

Program Governance/Leadership

The Program Evaluation Committee (PEC), which will consist of Imo Aisiku, Peter Hou, Raghu Seethala, Carolyn D'Ambrosio, and Michael Billington, will document formal, systematic evaluation of the curriculum at least annually, and will be responsible for rendering a written Annual Program Evaluation. The program will monitor and track fellow performance, faculty development, graduate performance, program quality, and will use the results of annual fellow and faculty evaluation of the program to improve the program, including progress on the previous year's action plan. The PEC will prepare a written plan of action to document initiative to improve performance in one of the areas described above and delineate how they will be measured and monitored.
