In addition to supporting basic surgical needs, the Department is an integral part of obstetrical and maternity cases in Labor and Delivery, Endoscopy, Interventional Radiology, MRI and CT scan studies, the Cardiac Catherization Lab, EP Studies and the Emergency Room.

    Since 2002, Stamford Hospital has partnered with U.S. Acute Care Solutions (USACS) to provide Physician and Physician Assistant coverage to our Emergency Department. USACS is the largest physician owned Emergency Medicine group in the country. Currently USACS provides care to more than 6 million patients annually in over 200 hospitals located across 20 states. Physician ownership means that local leaders are committed to growing with hospital partners to deliver superior patient care. USACS clinicians staff the adult Emergency Department at Stamford Hospital along with the Pediatric Emergency Department and the Immediate Care Center at the Tully Health Center.

    Patient experience is at the center of everything we do for patients. Most patients arriving to the Emergency Department will be placed directly in a treatment room and will bypass the waiting room. The majority of Emergency Department patients are seen by one of our Board-Certified providers within 30 minutes of arrival. A rigorous quality assurance program ensures that the best possible care is delivered to each and every patient. The Stanford Hospital Emergency Department has exceeded national benchmarks in providing quality care to patients with life-threatening emergencies such as heart attack, stroke and sepsis.

    The Department of Medicine at Stamford Health is a big tent, a “department of departments.” It encompasses 17 divisions representing diverse medical specialties, including more than 250 physicians as well as advanced practice nurses, nurse practitioners and physician assistants. These providers reflect a spectrum of practice arrangements, from affiliated community physicians to members of the Stamford Health Medical Group to hospital-based and contracted groups. Our residency program includes 21 housestaff in postgraduate years (PGY) 1 – 3, including 2 PGY-3 Chief Residents. Graduates of the training program have entered subspecialty fellowship programs or started careers as hospitalists or primary care physicians. Medical students from the Vagelos College of Physicians of Columbia University rotate on medicine and primary care clerkships in our department, and are joined by students from other medical schools on senior student electives and sub-internships. Nearly 100 of our attending physicians hold faculty appointments at Columbia.
