Massachusetts General Hospital (Mass General) is hardly general. The 200-year-old acute care hospital is Harvard Medical School's original and largest teaching hospital. With some 950 beds, Mass General has its main campus in Boston and operates several health centers in surrounding communities. Its specialized medical departments include cancer, cardiology and heart surgery, neurology and neurosurgery, and diabetes and endocrinology. As a leading research facility, Mass General hosts a number of clinical drug and device trials and has an annual research budget of more than $785 million. The hospital is a founding member of the Partners HealthCare System (along with Brigham and Women's).
