Beyond the click: Pixel tracking technologies and patient data security in hospitals

Area of Science:

• Health Informatics
• Cybersecurity
• Digital Health

Background:

• Digital tracking technologies are widely used for data collection.
• Their implementation in healthcare raises significant patient privacy and security concerns.
• Existing regulations like HIPAA may not fully cover modern tracking methods.

Purpose of the Study:

• To conduct a large-scale empirical analysis of pixel tracking on US hospital websites.
• To investigate the relationship between pixel tracking and data breach risks.
• To identify potential gaps in current healthcare privacy regulations.

Main Methods:

• Utilized historical website data from the Wayback Machine (2012-2023).
• Analyzed the presence and type of pixel tracking technologies on a sample of US hospital websites.
• Correlated pixel tracking usage with reported data breaches.

Main Results:

• 66% of analyzed hospital websites employed pixel tracking technologies.
• Third-party pixel usage was found to significantly increase the risk of data breaches.
• Tracking pixels often operate outside the scope of traditional healthcare privacy regulations like HIPAA.

Conclusions:

• Pixel tracking presents an underrecognized cybersecurity vulnerability in healthcare.
• There is a critical need to reevaluate privacy safeguards and regulatory oversight for digital tracking in hospitals.
• Addressing these risks is essential as healthcare increasingly adopts digital tools.
