An optimal code for patient identifiers.

How to distinguish 1 billion individuals by an identifier consisting of eight characters, allowing a reasonable amount of error detection or even error correction? Our solution of this problem is an optimal code over a 32-character alphabet that detects up to two errors and corrects one error as well as a transposition of two adjacent characters. The corresponding encoding and error checking algorithms are available for free; they are also embedded as components of the pseudonymisation service that is used in the TMF-the German telematics platform for health research networks.

Secondary use of the EHR via pseudonymisation.

The Electronic Health Record (EHR) has many secondary uses, such as health economy and health care research, or disease specific clinical or epidemiological research. For these uses in general the patient identity is not needed, therefore the data must be anonymised or pseudonymised. Whereas for one-time use of the data this procedure is straightforward, long-term data accumulation or the necessity of re-identification require a more sophisticated approach. This paper describes possible model architectures, developed for medical research networks, but useful in other contexts as well.
