Role-based access to patients clinical data: the InterCare approach in the region of Crete.

The basics of a particular Integrated Electronic Health Record (I-EHR) implementation are presented, as realised by the Patient Clinical Data Directory (PCDD) system. PCDD operates within the context of HYGEIAnet, the Integrated Healthcare Telematics Network of Crete. PCDD is based on a federation of autonomous information systems and provides to its authorized users alternative views of the health record as well as access and retrieval services to its geographically distributed segments. The data model of the PCDD is based on the Subjective Objective Assessment Plan (SOAP) model that originates from the primary healthcare domain. Access to detailed information on particular patients healthcare encounters is delivered via role-based authorization privileges and controls. The administration of the national healthcare organizations' business rules, for different user-groups, is made via a specially tailored and developed rule-editor.

Virtual workspaces in I2Cnet.

The objective of I2Cnet (Image Indexing by Content network) is to provide network-transparent content-based access to medical image archives as an Internet/intranet value-added service. Through a typical web browser, healthcare professionals interact with image collections, browse images similar to a query image, compare these images to images from other collections, and contribute their own images or comments. Specific I2Cnet services available on the World Wide Web (WWW) include image processing and feature extraction, content- and annotation-based search for images and image-related information, and authoring of annotations and image descriptions. Virtual workspaces provide the necessary mechanisms to support user sessions in I2Cnet, providing for service interoperability, persistence, and user interaction. In the course of a user session, which begins with a workspace log-in and ends explicitly with a workspace log-out or implicitly by exiting the browser, virtual workspaces maintain the common context.

Functional and control integration of an ICU, LIS and PACS information system.

The need for collaboration and data sharing among systems dedicated to individual functional areas and user groups has initiated major efforts towards the development of an integrated hospital information system. Major issues in the development of any integrated architecture that incorporates autonomous departmental systems include the development of commonly accepted interaction mechanisms, standardisation, the structure of the computerised patient record, its extensibility, as well as limitations multimedia data impose. This paper presents work done within project IHIS, a nationally funded project for the development of an integrated hospital information system that provides ICU staff with access to both the ICU assisting laboratory information system's data as well as radiological multimedia data.

The I2Cnet service architecture paradigm.

The main objective of the Image Indexing by Content network (I2Cnet) is to provide network-transparent content-based access to medical image archives based on a collection of interoperable Internet/intranet added-value services. This paper discusses I2Cnet, focusing on its service architecture paradigm. I2Cnet services such as image annotation, processing, description, and content-based retrieval, as well as the on-line collaboration service are presented. Exemplary user sessions are used to illustrate how virtual workspaces facilitate the interoperation of I2Cnet services, following the "network computer" approach to information management.
