Westchester Medical Center Health Network

Westchester Medical Center Health Network operates as an integrated healthcare system that delivers acute medical services across several hospitals and care centers in the Hudson Valley region of New York State. The network includes facilities such as HealthAlliance Hospital in Kingston, Margaretville Hospital in Margaretville, and Mountainside Residential Care Center, which together provide inpatient, outpatient, emergency, and specialty care to the communities they serve. Its core mission is to offer comprehensive clinical services ranging from routine primary care to complex tertiary treatments, supported by a workforce of physicians, nurses, and allied health professionals. The organization maintains a regional referral role, accepting patients from surrounding counties for advanced procedures and critical care interventions. In addition to hospital-based services, the network oversees residential care and rehabilitation programs that support long‑term patient recovery. By coordinating services across its member sites, the health network aims to improve access, continuity of care, and health outcomes for a diverse patient population.

The health network’s scale is reflected in its multi‑facility footprint, which enables it to serve a broad geographic area encompassing urban, suburban, and rural communities throughout the Hudson Valley. While specific patient volume or employee counts are not disclosed in the available sources, the presence of multiple acute care hospitals and residential care centers indicates a substantial regional presence. Distinguishing attributes of the organization include its emphasis on patient safety and its readiness to activate emergency protocols during disruptions, as demonstrated by the October 2023 cyberattack that affected IT systems across HealthAlliance Hospital, Margaretville Hospital, and Mountainside Residential Care Center. During that incident, the network instituted system‑wide shutdowns, diverted ambulances, and transferred patients to other network facilities while maintaining emergency walk‑in care for assessment and stabilization. The response involved collaboration with federal law enforcement agencies such as the FBI, a third‑party cybersecurity firm, and state health authorities, highlighting the organization’s capacity to engage external experts under crisis conditions. Throughout the restoration effort, the network prioritized clear communication with patients, staff, and the broader community to maintain trust and transparency. These characteristics underscore the network’s role as a resilient regional healthcare provider committed to safeguarding public health even amid operational challenges.
