Mount Sinai Health System

Mount Sinai Health System is a nonprofit academic medical system centered in New York City. It was established in 2013 through the combination of the Mount Sinai Medical Center and Continuum Health Partners, bringing together Mount Sinai Hospital and several hospitals formerly operated through Continuum. The system’s institutional roots are older: Mount Sinai Hospital opened in Manhattan in the nineteenth century, while several component hospitals have histories extending into the nineteenth and early twentieth centuries. The organization operates as an integrated health system rather than as a single hospital. Its activities include inpatient and emergency care, outpatient medicine, specialty and subspecialty services, ambulatory surgery, rehabilitation, behavioral health, community health programs, medical education, biomedical research, and clinical trials. Its principal academic partner is the Icahn School of Medicine at Mount Sinai, which conducts research and trains physicians, scientists, nurses, and other health professionals. The system also supports graduate medical education and a broad network of faculty and community physicians. The flagship institution is The Mount Sinai Hospital on the Upper East Side of Manhattan. Other major New York City facilities and brands have included Mount Sinai Morningside, Mount Sinai West, Mount Sinai Beth Israel, Mount Sinai Brooklyn, New York Eye and Ear Infirmary of Mount Sinai, and Mount Sinai South Nassau on Long Island. The system has also operated or affiliated with ambulatory, rehabilitation, specialty, and community-based sites. Service lines span cardiology, cancer, neurosciences, transplantation, orthopedics, women’s and children’s health, geriatrics, gastroenterology, emergency medicine, and population health. Mount Sinai’s positioning combines tertiary and quaternary referral care with a large urban delivery network. The system treats patients from New York and the wider region while serving local communities through primary care, emergency departments, outpatient clinics, and public-health initiatives. Its research identity is particularly associated with precision medicine, genomics, immunology, artificial intelligence, neuroscience, cancer, and health-equity research, although the scope of its academic work is much broader. The system has faced the operational pressures common to large urban hospitals, including high labor costs, capital requirements, uneven demand across campuses, and the financial effects of the COVID-19 pandemic. It has consequently pursued restructuring, service-line changes, outpatient expansion, partnerships, and cost-management measures. In 2024, longtime chief executive Kenneth L. Davis was succeeded by Brendan G. Carr, marking a leadership transition after more than a decade of system development under Davis. Mount Sinai remains a private nonprofit health system and is not a publicly traded company.

The history of Mount Sinai Health System combines the development of Mount Sinai Hospital with that of several independent New York hospitals that later became part of a common organization. Mount Sinai Hospital was founded in Manhattan in the nineteenth century to provide care to Jewish immigrants and other underserved New Yorkers. It evolved into a major teaching and research hospital and later became the central institution of the Mount Sinai Medical Center. The medical center developed close ties with medical education and research, ultimately becoming associated with the Icahn School of Medicine at Mount Sinai. Other component institutions followed separate paths. Continuum Health Partners was created in the 1990s through the consolidation of several New York hospitals, including Beth Israel Medical Center, St. Luke’s-Roosevelt Hospital Center, and New York Eye and Ear Infirmary. These hospitals served dense Manhattan and Brooklyn communities and maintained their own clinical identities, specialties, and local relationships. Their combination with Mount Sinai reflected the broader movement toward integrated delivery systems in the New York market, where hospitals sought scale in purchasing, information technology, physician organization, specialty care, and population health. In 2013, Mount Sinai Medical Center and Continuum Health Partners combined to form Mount Sinai Health System. The transaction brought the institutions under a common governance and operating structure while preserving recognizable hospital and specialty brands. The new system was designed to link community hospitals and ambulatory care with a major academic medical center, allowing patients to move among primary, specialty, inpatient, and highly complex referral services. Kenneth L. Davis, who had led Mount Sinai Medical Center, became the system’s chief executive. During the following decade, Mount Sinai invested in clinical integration, research capacity, outpatient facilities, digital health, and specialty programs. It expanded its regional presence through institutions such as Mount Sinai South Nassau and maintained a large network of physician practices and ambulatory locations. The Icahn School of Medicine remained a core part of the enterprise, supporting research in genomics, neuroscience, cancer, immunology, artificial intelligence, and other fields while providing the academic workforce for the hospitals. The COVID-19 pandemic placed exceptional pressure on the system’s New York hospitals in 2020. Mount Sinai became prominent in clinical treatment, public communication, epidemiological work, and research on testing, therapeutics, immunity, and post-acute illness. The pandemic also exposed the financial and operational vulnerability of urban hospital systems, contributing to later efforts to redesign services, improve efficiency, and balance inpatient capacity with outpatient and community care. Mount Sinai’s subsequent strategy has included concentration of some complex services, ambulatory growth, digital and virtual care, systemwide quality initiatives, and closer coordination among hospitals and physician practices. Some campus plans, especially those involving Mount Sinai Beth Israel, have generated public and regulatory scrutiny because of their effects on emergency and inpatient capacity in Lower Manhattan. In 2024, Brendan G. Carr became president and chief executive officer, succeeding Davis. The system continues to operate as a private nonprofit academic health system serving New York City and surrounding communities.
