Attorneys working with ClassAction.org are investigating whether a class action lawsuit can be filed against Tenet Healthcare Corporation, one of the largest for-profit healthcare systems in the country, over concerns that it may have shared certain patients’ private information without permission.
They believe patients who used the following California hospitals’ websites, which are or were operated by Tenet, may be affected:
- Fountain Valley Regional Hospital
- Lakewood Regional Medical Center
- Los Alamitos Medical Center
- Doctors Hospital of Manteca
- Emanuel Medical Center
- San Ramon Regional Medical Center
- Placentia-Linda Hospital
- Hi-Desert Medical Center
Specifically, the attorneys have reason to believe Tenet may have used tracking tools that secretly collected data about patients as they interacted with its websites and then transmitted this information to Facebook and Google.
These tools could have been used to track any information input by users as they navigated the sites, revealing sensitive data about their medical symptoms, conditions and treatments.
How Could Tenet Be Violating My Privacy?
Many website operators use tracking tools on their websites to gather data about their users.
One such tool, called the Meta pixel, can be embedded on any webpage and programmed to capture nearly every action a visitor takes on the page, such as the buttons they click, the searches they perform and the content they view. This data can then be used by both the website operator and Meta to better target advertisements to their users.
Google’s tracking tool, which transmits data to Google Analytics, functions similarly.
Attorneys are specifically looking into whether the websites mentioned above used the Meta pixel and Google Analytics in a manner that exposed patients’ personal and medical information. It’s possible that this data was shared with Meta along with each person’s Facebook ID, which is a unique identifier that could potentially be used to match the person’s information with their individual Facebook profile.
These suspected data-sharing practices may violate certain wiretapping laws, which prohibit the interception and disclosure of an individual’s electronic communications without their consent.
How Could a Lawsuit Help?
A class action lawsuit, if filed and successful, could help compensate those affected by Tenet’s suspected data-sharing practices. It also has the potential to ensure that Tenet handles patients’ data appropriately moving forward.
