LuMiR: A Region-wide Virtual Healthcare Record (2008)
This article is the first synthetic and relatively complete presentation of the LuMiR project, carried out in the Basilicata region within the Italian RMMG program. It sets the general direction of the project: the transition from organizational-centric services to collaborative and patient-centric care processes, supported by a regional infrastructure of web services having the Virtual Healthcare Record at its center.

Title: LuMiR: A Region-wide Virtual Healthcare Record
Authors: Mariangela Contenti, Gregorio Mercurio, Fabrizio L. Ricci, Luca D. Serbanati
Year: 2008
Type: article / project communication
Theme: medical informatics, regional interoperability, VHR, HL7, SOA
The article places LuMiR within the Italian e-Health programs and presents it as the implementation of the RMMG program in Basilicata, centered on a regional Virtual Healthcare Record.
The article's figures
The article contains the following important figures:
- Figure 1 – the context of the LuMiR system, with the V-EHR in the center and its links with EMRs, laboratories, radiology, pharmacy, regional systems and the patient themselves.
- Figure 2 – the stratified architecture of the system, with local components, adapters, proxies, the broker and the VHR.
- Figure 3 – the LuMiR conceptual model centered on Contact and Episode of Care.
- Figure 4 – the D-MIM of the VHR services realization area.
Conceptual contribution and place of the work
Although the article is a collective work, it is important to me because it sets down for the first time, in a public and relatively concentrated form, several ideas that will return throughout my subsequent research in medical informatics: the Virtual Healthcare Record as an active longitudinal core, modeling on contacts and episodes of care, as well as the transition from a purely documentary interoperability to an integration closer to the real care processes.
In this sense, the article marks an intermediate stage between the general idea of a virtual clinical record and the later developments that will lead to the Digital Healthcare Ecosystem, agentification and, much later, the Health Digital State.
Large description
1. The Italian context and the RMMG program
The article begins by placing the project within the context of Italian e-Health policies: Tavolo di Sanità Elettronica, the IBSE core infrastructure and the Rete dei Medici di Medicina Generale e Pediatri di Libera Scelta program. LuMiR is presented as the regional enactment of this program in Basilicata, with the participation of all public health organizations in the region.
2. The transition from the organizational model to the patient-centric one
One of the most important things stated here is that the current medical environment requires interdisciplinary processes, fast access to relevant information at the point of care and decision support to avoid errors and provide adequate treatments. In this context, LuMiR is defined as a system meant to support the move from organisation-centric services to patient-centric services, based on inter-organizational cooperation and information exchange between stakeholders.
3. The VHR as the core of the platform
From a technological and conceptual point of view, the core of the project is the Virtual Healthcare Record, described as a distributed platform that integrates clinical information from medical events occurring throughout the citizen's life. The VHR receives clinical and administrative data about medical encounters, and in return provides the health status, medical history and ongoing treatments of Basilicata citizens.
4. From the clinical document to the medical event
The article clearly shows that digitally signed HL7 CDA clinical documents remain the primary source of information, but they do not represent the conceptual center of the system. The relevant information is extracted from these documents, associated with the clinical event that generated them, and integrated into the VHR. In parallel, the documents are stored and published through IBIS services. This mechanism makes it possible both to preserve the legal validity of the documents, and to reorganize the information into a more clinically useful form.
5. Stratified architecture
One of the clearest contributions of the article is the presentation of the LuMiR architecture. This is made up of three layers: the SPCoop infrastructure for cooperation between public administrations, the intermediate layer with IBIS and common services for authentication / authorization / transactions, and an upper SOA layer where participating applications exchange HL7 v3 messages and HL7 CDA documents, using request/reply and publish/subscribe interactions. On top of these layers, the authors already see the possibility of building composite services and executable workflows.
6. Contact and Episode of Care
Beyond architecture, the article also contains a very important conceptual step: the LuMiR information model is centered on two concepts, Contact and Episode of Care. A contact represents a set of relevant health services provided during a patient encounter, and these services belong to one or more episodes of care, each referring to a health problem. In addition, the model is divided into four main areas: contacts and episodes, clinical guidelines, individual treatment plans and the actual realization of services.
7. A shift in focus: from the document to the VHR informational domain
Perhaps the most significant statement in the final part of the article is that the modeling activity was not focused on clinical documents, but on the informational domain of the VHR. This choice clearly shows that the intention of the project was not just to build a document persistence and routing system, but a richer informational core, capable of supporting continuity of care and clinically meaningful queries.
8. The article's place in subsequent evolution
Viewed retrospectively, the 2008 text is still very close to the logic of regional interoperability infrastructures and HL7 / CDA / IBIS standards. But precisely within this framework it already introduces the seeds of further developments: the VHR as an entity richer than a repository, the contact as a more relevant unit than the isolated document, the episode of care as a longitudinal unit and the idea that, on top of the infrastructure, composite services, workflows and process-oriented applications can appear. From here, in the following years, it will lead to the Digital Healthcare Ecosystem and agent-oriented architectures.
