UW Medicine

UW Medicine is a United States-based healthcare organization that provides medical services to patients and maintains protected health information as part of its clinical and administrative operations. The organization handles sensitive patient data including names, addresses, account numbers, medical record numbers, details of treatment providers, and descriptions of medical services, which are integral to patient care, billing, and record-keeping. This data management situates UW Medicine within the broader healthcare sector, where entities are entrusted with personal health information and must adhere to regulatory standards for privacy and security. Its operational scope involves direct patient interactions and reliance on various service vendors, creating a landscape where data protection and third-party risk management are essential components of its compliance and operational frameworks. The nature of its work requires secure handling of health records to support treatment continuity and administrative functions, aligning with common practices among medical providers.

In June 2022, UW Medicine experienced a data security incident tied to its mail service vendor, Kaye-Smith, which was targeted by a ransomware attack. This third-party breach compromised the protected health information of approximately 3,800 individuals, exposing data elements such as patient names, addresses, account numbers, medical record numbers, provider details, and descriptions of medical services, while Social Security numbers, birth dates, and financial data remained unaffected. The incident affected multiple healthcare organizations using the same vendor, including Geisinger and Seattle Children's, illustrating the shared risks across the healthcare supply chain. Kaye-Smith, as the responsible third party, managed the notification process for affected individuals, highlighting the contractual dependencies healthcare entities have on external partners for certain operational services. This event underscores UW Medicine's exposure to cybersecurity threats through vendor relationships and the critical importance of overseeing third-party data handling practices. The breach also reflects the organization's experience in navigating data security incidents within the regulatory environment governing healthcare information protection.
