A proposed class-action lawsuit alleges that it allowed tech companies to access private patient data for advertising purposes. The complaint, filed by a California patient known as John Doe, claims that the health system’s website and patient portal contained code that granted companies—including Google, Bing, Twitter, Adobe, and Quantum Metric—access to personal information. Kaiser joins a growing list of health systems being sued over their alleged sharing of patient information with tech companies via consumer-tracking technology. The complaint asks for damages and injunctive and declaratory relief. Kaiser Permanente is the health system awaiting approval of an acquisition of Pennsylvania’s Geisinger Health System.
