A new state-of-the-art hospital is in the works for the Stony Brook Southampton campus through a partnership between the State University at Stony Brook and Southampton Hospital, according to a nonbinding letter of intent signed by both parties and announced in a release dated Oct. 1. The 125-bed facility would join the university’s health care system, with a goal of the two hospitals’ working together to “improve health care quality and access, coordination of care, and efficiency for their patients.”
