Several Californians sued Sutter Health and MemorialCare this week over allegations that an AI transcription tool was used to record them without their consent, in violation of state and federal law.

The proposed class-action lawsuit, filed on Wednesday in federal court in San Francisco, states that, within the past six months, the plaintiffs received medical care at various Sutter and MemorialCare facilities.

During those visits, medical staff used Abridge AI. According to the complaint, this system “captured and processed their confidential physician-patient communications. Plaintiffs did not receive clear notice that their medical conversations would be recorded by an artificial intelligence platform, transmitted outside the clinical setting, or processed through third-party systems.”

The complaint adds that these recordings “contained individually identifiable medical information, including but not limited to medical histories, symptoms, diagnoses, medications, treatment discussions, and other sensitive health disclosures communicated during confidential medical consultations.”

In recent years, Abridge’s software and AI service have been rapidly deployed across major health care providers nationwide, including Kaiser Permanente, the Mayo Clinic, Duke Health, and many more.
