HIPAA Compliance and De-identification

To be considered not electronic protected health information (ePHI) the UC implementation of TriNetX is de-identified. The UC instance of TriNetX employs a de-identified data set that excludes all of the eighteen HIPAA identifiers. This de-identification includes the following trifling modifications to the underlying data, called obfuscation:

• All ages over 89 are indicated as ≥90.
• Results will show ±x for additional obfuscation.
• Counts of less than 10 will show as <10.

The detailed, absolute data can be extracted through the Honest Broker, CHI.
