For Yale New Haven Hospital, 2016 was a year of change, challenge and growth. While we again faced state budget cuts, hospital taxes, a gubernatorial moratorium on affiliations and regulatory challenges this year, we continued to provide greater value to our patients and invest in clinical programs, facilities and technology resources.
U.S. News & World Report again recognized Yale New Haven Hospital among the best in the nation in 11 adult and six pediatric specialties.
Patient volume increased this year, and we finished 2016 with an operating margin of 3.2 percent. We discharged 79,490 inpatients and handled about 1.3 million outpatient visits. We completed the fourth year of our integration with the Hospital of Saint Raphael and, since 2012, the integration has saved about $291 million in operating costs. At the same time, we have invested more than $100 million in capital improvements on the Saint Raphael Campus.
This year we celebrated the 20th anniversary of the Yale New Haven Health System, which has benefited our Hospital, as well as Bridgeport and Greenwich hospitals and Northeast Medical Group. We also changed our brand to reflect the increasing importance and strength that Yale New Haven Health offers, and we added two new hospitals—Lawrence + Memorial and Westerly—to our Health System.
Our achievements in in 2016 would not have been possible without the dedication and contributions of our physicians, employees and volunteers, as well as the guidance and commitment of our board members and the generous support of donors and friends in the community. Thank you for bringing strength to Yale New Haven Hospital as we continue our service to others.
