The Reason

A Virtual Euro-Mediterranean hospital structure is expected to:

‣provide ease of access to care

‣provide shared care and continuity of care at regional, national

and international level

Enablers

‣Create a network of healthcare delivery

‣Inter-connect participating hospitals healthcare processes (crossorganizational

healthcare processes)

‣Support the cross-organizational healthcare processes by

information and communication technology (ICT)

‣ Provide integrated patient information at the point of care

(Electronic Patient Record - EPR)

‣Telemedical services

‣E-Learning

Medical Information

‣Large and increasing in size

‣Critical confidential

‣Stored at geographically dispersed healthcare units

‣Different format, structure and incompatible semantics

Electronic patient records

‣ provide secure access to integrated patient information irrespective

of the location where it has been stored

‣ support the continuity of healthcare and the shared care

‣ reduce practice variability and patient care costs

‣ improve medical decision making

Role of an EPR in VEMH

‣ Support the cross-organizational healthcare processes executed

‣ within the boundaries of a health district (e.g. the case of a patient

transfer to another healthcare organization for continuation of care),

‣ within the boundaries of a country (integrated patient data at

national level) and

‣ among the hospitals of the VEMH (e.g. a second medical opinion)

‣ Support the telemedicine services (e.g. tele-consulation)

‣ Form the basis for creating virtual healthcare workgroups at regional,

national and international level

Electronic Patient Record Requirements

‣Address the integrated information needs of the participating

hospitals

‣ Authorized access to integrated patient information.

‣ Timely patient information exchange among the participants in

healthcare delivery processes.

‣Support the collaboration and coordination needs of the participating

organizations

‣Support interoperability among heterogeneous healthcare systems.

‣Preserve existing investments on information systems made by the

participating healthcare organizations.

The web-based EPR envisaged

Web-Based EPR

‣ is based on a horizontal, process-oriented view of healthcare

delivery

‣ supports the cross-organizational healthcare processes executed

between the healthcare organizations participating in the

VEMH

‣ preserves existing investments on information systems made by

the participating healthcare organizations.

Virtual Euro-Mediterranean Hospital - V E M H

The EPR system will

‣ Provide access to already existing patient data in a standard

format and structure using the same semantics

‣ Provide tools for storing patient data

‣ Provide tools for selecting and exchanging portions of

integrated patient data (e.g. concerning a specific patient

medical problem)

‣ Provide advanced search capabilities for retrieving anonymous

patient data for knowledge acquisition, comparison of

performance and research purposes

Implementation Methodology

‣ Identify a number of cross-organizational healthcare processes

and develop corresponding process models

‣ Study these models and specify

• the collaboration and coordination needs among the

participating hospital

• the information retrieval and exchange activities

‣ Design a system architecture that enables incorporating

heterogeneous information systems

‣ Incorporate to the system a security policy

‣ Create a prototype implementation

‣ Evaluate system implementation

System architecture

‣ Service-oriented approach to support the global information

needs and the collaboration and cooperation needs of the

participating organizations

‣ Document-oriented approach (XML clinical documents

encoded into CDA)

• documents are the basic information objects

• document exchange is the basic inter-organizational

interface

‣ Web services and/or grid services implement the information

retrieval and exchange activities of the cross-organizational

healthcare processes

Proposed Technologies

‣ XML for data format

‣ XML-based CDA for structuring patient data in the form of

standard XML clinical documents

‣ ICD-10 and SNOMED terminology systems for coding patient data

using the same semantics

‣ Web services and/or grid services for producing interoperable and

flexible applications that are able to interact with existing

information systems of the hospitals
