In June 2022, a nonprofit news site called The Markup released a report stating that hospitals using Meta Pixel may be releasing patient data to Meta Platforms, Inc. (previously Facebook, Inc.). Since this report was released, many of the hospitals identified in the report removed pixel technology from their websites. In addition, some hospitals have released public breach notices and reported potential data privacy breaches to the US Department of Health and Human Services (HHS) Office of Civil Rights (OCR). Most recently, on October 20, 2022, Advocate Aurora Health, a large health system located in the Midwest, released a notice publicly announcing its potential pixel breach, which may affect as many as three million patients.
