IADIS International Conference WWW/Internet 20102. VHCRVirtual HealthCare Record (VHCR) is the central part of our application. VHCR is not a documentrepository; instead it is a healthcare service provider. It holds data extracted from medical documents in afiner grained model than the documental model permits. The medical document from where VHCR extractedits information to populate the data structure is not lost. Integration is done by analyzing the document in itsmedical context (Episode Of Care, Health Issue) and making the necessary updates in the record. (Chronaki,2003).In effect integration and interpretation transforms the information received from the PoS from adocument based-model into our model, based on an ontology derived from HL7 RIM v3,(HL7, 2007) seeFig. 1. Documenting the health status of a patient is done by using health issues. A health issue is a singlehealth problem like asthma, a broken leg etcA health issue has a life cycle of its own spanning across a time period. In this period we can have moreepisodes of care, for example a patient with asthma has this health issue all his life.An episode of care is a workspace which logically groups relevant data from an instance of the treatment.This way a doctor can download from the VHCR only the information from the current episode. Also we useepisodes of care for a finer grained access to information, the patient can give privacy rights based on theassociation (,).Episodes of care can be active, suspended or closed at a moment in time. Closed episodes are archived forfuture reference.An episode of care consists of morecontacts. A contact is an encounterbetween a patient and a health careprovider. Each contact has as anoutcome a document, stored in arepository and interpreted by theVHCR.During a contact the health careprovider offers a number of services tothe patient. These services includeprescription of medicine, referrals forfurther analysis or specializedprocedures. These care services can beatomic or can be grouped in a careplan, a workflow of services to beexecuted and monitored locally.Results of medical analyses are alsoavailable in the health record. They canrange from blood readings to x-rayimages.Figure 1. VHCR Information Model3. VHCR IN THE HEALTHCARE ECOSYSTEMWe envision the healthcare context as a complex business digital ecosystem comprising agencies, nationaland international regulations, business processes, models and contractual framework. The stakeholders areparties with a permanent or temporary interest in the healthcare process who are represented by unique,customized avatars, implemented by software agents. (Serbanati et al, 2005) In this complex virtual world theVHCR is itself an organization of agents (Wooldridge, 2002 & Grossi et al, 2006), able to communicate withother digital components and to participate in business processes. (Huhns, 2008 & Zambonelli et al, 2001).The focus of this paper is to describe the multi-agent system of VHCR, called VHCR Agency. (see Fig. 2)273
