The Division of Acute Care Surgery and Critical Care team comprises highly skilled, board-certified attending (senior-level) surgeons, fellows, and residents (licensed doctors who are supervised by senior surgeons), nurse practitioners, registered nurses, physician assistants, and professional support staff. Each member of our team is dedicated to providing exemplary care to patients, excellent service to referring physicians, and valuable educational and training programs to health care providers and the general community.
The members of our team, all of whom have extensive experience in caring for acutely ill or injured patients, work collaboratively with a multidisciplinary group of physician specialists and other caregivers throughout the Beth Israel Deaconess Medical Center community. Our team approach ensures that patients benefit from well-coordinated, multidisciplinary care tailored to their specific needs.
We also offer the services of social workers to help patients and family members cope with any psychological or social issues that may arise as a result of a serious injury or illness. In addition, patients have access to a broad range of other care providers, including physical therapists, respiratory therapists, nurse case managers, and many others.
