Building application-related patient identifiers: what solution for a European country?

We propose a method utilizing a derived social security number with the same reliability as the social security number. We show the anonymity techniques classically based on unidirectional hash functions (such as the secure hash algorithm (SHA-2) function that can guarantee the security, quality, and reliability of information if these techniques are applied to the Social Security Number). Hashing produces a strictly anonymous code that is always the same for a given individual, and thus enables patient data to be linked. Different solutions are developed and proposed in this article. Hashing the social security number will make it possible to link the information in the personal medical file to other national health information sources with the aim of completing or validating the personal medical record or conducting epidemiological and clinical research. This data linkage would meet the anonymous data requirements of the European directive on data protection.

Proposal of a French health identification number interoperable at the European level.

The French ministry of Health is setting up the Personal Medical Record (PMR). This innovative tool has long been expected by French Health Authorities, Associations of Patients, other Health's associations, those defending Individual Liberties and the French National Data Protection Authority. The PMR will lead to improvements in many areas such as Diagnosis (Research and monitoring) Healthcare (Management of emergencies, urgent situations, Temporal health monitoring and evaluation), Therapy (Cohorts of patients for Clinical trials and epidemiological studies). The PMR will foster safe healthcare management, clinical research and epidemiological studies. Nevertheless, it raises many important questions regarding duplicates and the quality, precision and coherence of the linkage with other health data coming from different sources. The currently planned identifying process raises many questions with regard to its ability to deal with potential duplicates and to perform data linkage with other health data sources. Through this article, using the electronic health records, we develop and propose an identification process to improve the French PMR. Our proposed unique patient identifier will guarantee the security, confidentiality and privacy of the personal data, and will prove to be particularly useful for health planning, health policies and research as well as clinical and epidemiological studies. Finally, it will certainly be interoperable with other European health information systems. We propose here an alternative identification procedure that would allow France to broaden the scope of its PMR project by making it possible to contribute to public health research and policy while increasing interoperability with European health information systems and preserving the confidentiality of the data.

How to manage secure direct access of European patients to their computerized medical record and personal medical record.

The multiplication of the requests of the patients for a direct access to their Medical Record (MR), the development of Personal Medical Record (PMR) supervised by the patients themselves, the increasing development of the patients' electronic medical records (EMRs) and the world wide internet utilization will lead to envisage an access by using technical automatic and scientific way. It will require the addition of different conditions: a unique patient identifier which could base on a familial component in order to get access to the right record anywhere in Europe, very strict identity checks using cryptographic techniques such as those for the electronic signature, which will ensure the authentication of the requests sender and the integrity of the file but also the protection of the confidentiality and the access follow up. The electronic medical record must also be electronically signed by the practitioner in order to get evidence that he has given his agreement and taken the liability for that. This electronic signature also avoids any kind of post-transmission falsification. This will become extremely important, especially in France where patients will have the possibility to mask information that, they do not want to appear in their personal medical record. Currently, the idea of every citizen having electronic signatures available appears positively Utopian. But this is yet the case in eGovernment, eHealth and eShopping, world-wide. The same was thought about smart cards before they became generally available and useful when banks issued them.

Unique patient concept: a key choice for European epidemiology.

The French Ministry of Health is setting up the personal medical record (PMR or DMP for Dossier Médical Personnel in French). This innovating tool is highly expected and will be extremely useful for the therapeutic follow-up as well as for epidemiological studies on which public health policies are based. Therefore the currently planned identifying process should prevent any epidemiological use of these data. Numerous scientific organisations have alerted government powers about the threat that this impairment represents, and they wish to promote some secure procedures that exist, which have already proved their efficiency at the national and international level.
