A Wisconsin specialty clinic that gets its Epic EHR access through Advocate Aurora Health said 134,000 patients may have had their personal and health information compromised in a data breach involving the health system, which has dual headquarters in Downers Grove, Ill., and Milwaukee.
Green Bay-based BayCare Clinic recently started notifying the patients that data such as names, appointment information and electronic health messages may have been inadvertently shared with Google or Facebook after Advocate Aurora Health had used "pixel" ad-tracking technology on its Epic patient portal, MyChart, and LiveWell app and website. Advocate Aurora Health reported the breach, which affected as many as 3 million patients, in October and said it disabled the technology.
BayCare Clinic said in the notice that "pixels would be very unlikely to result in identity theft or any financial harm, and we have no evidence of misuse or incidents of fraud stemming from this incident."
