FAQs About Our Bodies, Our Data

What is Our Bodies, Our Data by Adam Tanner about?

Our Bodies, Our Data exposes the multi-billion-dollar trade in anonymized medical records, prescriptions, and insurance claims sold by data brokers to pharmaceutical companies, insurers, and marketers. Adam Tanner investigates how this hidden industry prioritizes profit over patient privacy, highlighting risks of re-identification and the lack of comprehensive health records for actual care.

Who should read Our Bodies, Our Data?

This book is essential for healthcare professionals, policymakers, privacy advocates, and anyone concerned about data ethics. It offers critical insights for patients seeking to understand how their medical information is commercialized without consent.

Is Our Bodies, Our Data worth reading?

Yes—Tanner’s investigative rigor and clear storytelling make it a landmark work on medical privacy. It sheds light on systemic exploitation in healthcare data markets, offering a compelling case for regulatory reform.

How does medical data get sold without patient consent?

Hospitals, pharmacies, and insurers sell anonymized records to data brokers like IMS Health (now IQVIA), which aggregate billions of patient profiles. These dossiers—stripped of names but retaining identifiers like birth year and doctor details—are monetized for drug marketing and research.

What are the risks of re-identifying anonymized medical data?

Advanced algorithms can cross-reference anonymized data with public records to reveal identities, exposing patients to discrimination, insurance denial, or employment issues. Tanner warns that purported “anonymization” often fails to protect privacy.

Tanner argues that while corporations profit from patient data, individuals struggle to access unified health records. This paradox undermines care quality while enabling unchecked commercial exploitation.

What solutions does Adam Tanner propose for medical data privacy?

The book advocates for patient ownership of health data, transparency in data sales, and stricter regulations akin to European GDPR. Tanner emphasizes empowering individuals to control how their information is shared.

How does Our Bodies, Our Data compare to Tanner’s previous work What Stays in Vegas?
