The NUCLEUS integrated electronic patient dossier breakthrough and concepts of an open solution

This paper addresses the requirements of healthcare providers and hospital managers vis-à-vis electronic patient records that can be integrated. It starts from some critical failure factors, found with previous attempts to standardise the electronic health record. Standardisation appears to be the key issue: the subject of standardisation requires delicate positioning. Technology must provide us with the means to obtain the standardised foundation for an integrated health record concept, which can be completely configured and customised to meet the requirements of health professionals and institutions involved. NUCLEUS, project A2025 in the AIM programme, has taken on this endeavour, and with good success. This paper summarises the benefits of this approach for various categories of people interested in using electronic patient records. Moreover, it illustrates NUCLEUS' contribution to achieving seamless integration of care. Furthermore, this paper explains the conceptual innovations that have been achieved in the NUCLEUS project. It consolidates the main concept of Act Management, structuring the professional primary process as well as the interprofessional communication. These concepts are subsequently expanded to include the key elements of the NUCLEUS integrated electronic patient record. Next, the paper reflects on what has appeared to be one of the critical success factors of the electronic patient record: its configuration and customisation facilities. These facilities make it possible to access the patient record at various intuitive aggregation levels and to make the integrated patient record 'look like' the individually specialised record of the respective healthcare professionals. Finally, the paper addresses various topics required to facilitate the successful implementation and operation of the NUCLEUS integrated electronic patient record like security, integrity, message communication, distribution, heterogeneity and the context of the hospital information system.
