Overview

Northwell Health is a nonprofit integrated health system headquartered in New Hyde Park, New York. It operates hospitals, outpatient facilities, physician practices, long-term-care services, rehabilitation programs, behavioral-health services, emergency medical services, medical education programs, and research activities across the New York metropolitan region. Its principal service area includes Long Island, New York City, and parts of Westchester County. The organization was created in 1997 through the combination of the North Shore Health System and the Long Island Jewish Medical Center system. For much of its history it operated under the North Shore-LIJ or North Shore–Long Island Jewish name. That identity was increasingly difficult to use as the organization expanded beyond its original Long Island base, and in 2015 the system adopted the Northwell Health name. The rebrand was intended to present the organization as a broader regional health network rather than as a system defined by two founding institutions. Northwell's service model combines hospital-based care with ambulatory and community services. Its network includes tertiary and quaternary hospitals, community hospitals, specialty facilities, urgent and primary-care locations, physician practices, home-care and hospice services, and other post-acute programs. The system also supports medical education through the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, established in partnership with Hofstra University, as well as graduate medical education and clinical research. The brand became especially visible during the COVID-19 pandemic because its hospitals treated large numbers of patients in the New York region during the first major United States outbreak. Northwell also received international attention in December 2020 when critical-care nurse Sandra Lindsay, who worked at Long Island Jewish Medical Center, became the first person in the United States to receive a COVID-19 vaccine outside a clinical trial. The event made Northwell a prominent setting in the public rollout of COVID-19 vaccination. Northwell is not a publicly traded corporation. It is a nonprofit health system governed through a board structure and supported by patient-service revenue, philanthropy, research activity, and other healthcare operations. Its brand positioning emphasizes coordinated care, clinical expertise, medical research, education, and access across a large regional network. Because the organization includes many hospitals and affiliated services, individual facilities retain their own local identities while operating within the Northwell system.

History

Northwell Health traces its institutional history to the healthcare organizations that served Long Island and the surrounding New York region before the Northwell name existed. The modern system was formed in 1997 through the merger of the North Shore Health System and the Long Island Jewish Medical Center system. The combination created a larger nonprofit network with hospital, physician, ambulatory, educational, and research capabilities. For many years, the organization was known as the North Shore-LIJ Health System, also written as North Shore–Long Island Jewish. The name reflected the system's principal founding institutions: North Shore University Hospital and Long Island Jewish Medical Center. As the network added facilities and expanded into New York City and other parts of the metropolitan area, the legacy name became less representative of the full organization. In 2015, the system introduced the Northwell Health brand. The change unified the system under a shorter name while allowing hospitals and established institutions to retain their local identities. Northwell subsequently developed as an integrated delivery system rather than solely a collection of inpatient hospitals. Its activities include acute-care hospitals, specialty hospitals, outpatient centers, emergency and urgent-care services, physician practices, home care, hospice, rehabilitation, behavioral health, long-term care, and other community programs. This structure allows the organization to manage care across different settings, although the exact services vary by facility. Education and research are central parts of Northwell's institutional identity. In partnership with Hofstra University, the system supports the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell. The medical school opened in 2011 and is connected to Northwell's clinical network, graduate medical education programs, and research enterprise. Northwell also operates or supports institutes focused on areas including cancer, cardiovascular medicine, neuroscience, pediatrics, women's health, and population health. The organization played a major role in the New York response to the COVID-19 pandemic in 2020. Its hospitals treated patients during the first regional surge, and the system publicized clinical protocols, capacity expansion, and research activity. Northwell gained further national visibility when Sandra Lindsay, a critical-care nurse at Long Island Jewish Medical Center, received a COVID-19 vaccine on December 14, 2020. The vaccination was widely recognized as the first administered in the United States outside a clinical trial and became a symbolic moment in the start of the national vaccine campaign. Northwell remains a nonprofit health system rather than a listed company. It is led by a professional executive team and governed through nonprofit institutional structures. Its current brand represents a broad regional healthcare platform whose major activities span patient care, medical education, biomedical research, public-health initiatives, and community services.
