D3.2 Evaluation results of the test plans implemented during real events

Strong expectations on electronic exchanges or shared medical documents from healthcare professionals and patients are pushing decision makers and stakeholders to develop quickly efficient and structured data enabled health IT infrastructures. One of the challenges of this paradigm shift is to provide at the point of care interoperable solutions in full compliance with regulations, ethics, organizational and technical states of the art. This paper describes this approach developed as a four steps process and defines the basic concepts for designing an interoperability infrastructure. For each of the steps, examples will be provided and discussed accordingly with the different interoperability layers (legal, policy, process, information and technical) developed in the Refined eHealth European Interoperability Framework (ReEIF) (eHealth Network, 2015).

This problem is particularly acute in cancerology because patients may be treated for many years and undergo a variety of examinations. Recent advances in technology make it feasible to gain access to medical records anywhere and anytime, allowing the physician or the patient to gather information from an "ephemeral electronic patient record". However, this easy access to data is accompanied by the requirement for improved security (confidentiality, traceability, integrity, ...) and this issue needs to be addressed. In this paper we propose and discuss a decentralised approach based on recent advances in information sharing and protection: Grid technologies and watermarking methodologies. The potential impact of these technologies for oncology is illustrated by the examples of two experimental cases: a cancer surveillance network and a radiotherapy treatment plan. It is expected that the proposed approach will constitute the basis of a future secure "google-like" access to medical records.

We address the issue of integrating anatomical pathology department to the healthcare enterprise. The pathology workflow from order to report, including specimen process and image acquisition was modeled. Corresponding integration profiles were addressed by expansion of the IHE (Integrating the Healthcare Enterprise) initiative. Implementation using respectively DICOM Structured Report (SR) and DICOM Slide-Coordinate Microscopy (SM) was tested. The two main integration profiles--pathology general workflow and pathology image workflow--rely on 13 transactions based on HL7 or DICOM standard. We propose a model of the case in anatomical pathology and of other information entities (orders, image folders and reports) and real-world objects (specimen, tissue samples, slides, etc). Cases representation in XML schemas, based on DICOM specification, allows producing DICOM image files and reports to be stored into a PACS (Picture Archiving and Communication System.

This objective could appear easy to reach but only in theory because in practice many name are misspelled or erroneous and a great attention has to be paid to define what is the best identifier to link medical record. As a linkage using less informative identifiers could lead to linkage errors, it is essential to quantify the information associated to each identifier. The aim of this study was to estimate the discriminating power of different identifiers susceptible to be used in a record linkage process. This work showed the interest of three identifiers when linking data concerning a same patient using an automatic procedure based on the method proposed by Jaro; the date of birth, the first and the last names seemed to be the more appropriate identifiers. Including a poorly discriminating identifier like gender did not improve the results. Moreover, adding a second christian name, often missing, increased linkage errors. On the contrary, it seemed that using a phonetic treatment adapted to the French language could improve the results of linkage in comparison to the Soundex. However, whatever, the method used it seems necessary to improve the quality of identifier collection as it could greatly influence linkage results.

La plupart de ces tentatives ont échoué, principalement pour deux raisons liées aux difficultés de mise en place d'un identifiant unique pour le patient et à l'absence de standardisation des dossiers médicaux. Dans cet article nous discutons l'intérêt d'une solution pragmatique reposant sur l'accès aux données déjà collectées et stockées de façon décentralisée, grâce à la mise en place d'un système de recherche et d'accès aux données réparties du patient. L'originalité de cette procédure repose sur des avancées technologiques, notamment les techniques de grille et de tatouage. Les données déjà standardisées pourraient bénéficier d'une gestion centralisée. Ceci conduirait à mettre en place un système mixte (décentralisé pour les données standardisées et centralisé pour les données déjà standardisées). ABSTRACT. For more than 20 years, many countries have been trying to set up a standardized medical record (regional or national). Most have not reached this goal, essentially due to two main difficulties related to patient identification, and the standardization of medical records. We propose here the non-centralized management of medical records relying on a specific procedure that gives the patient access to his distributed medical data, wherever it is located. The originality of this procedure relies on new advances in technology, which make it possible to envisage access to medical records anywhere and anytime, thanks to Grid and watermarking methodologies. Of course, all existing standardised information could be more easily centralised. As a consequence, a mixed system (decentralised for unstructured data and centralised for already structured data) could be proposed.
