Summary Hospital Information Systems have been emerging towards Health (HIS) for more than a decade. spread across institutional borders, and regional health networks are being supported. Furthermore, E-Health is starting to become reality. In the same time, HIS functionality has significantly improved: systems by far comprehensive, providing essential information knowledge care professionals, supporting quality management, improving patient safety, means inform patients. Old new problems,...

This article describes the design of a generator tool for rapid application development. The is an integral part healthcare information system, and newly developed applications are embedded into system from very beginning. tool-generated based on document oriented user interaction paradigm. A significant feature support intra- interdepartmental clinical processes by means providing flow between different groups. For flexible storage applications, generic EAV-type (Entity-Attribute-Value)...

Healthcare information systems play an important role in improving healthcare quality. As providing increasingly changes from isolated treatment episodes towards a continuous medical process involving multiple professionals and institutions, there is obvious need for system to support processes span the whole network. A suitable architecture such must take into account that it has work as integral part of complex socio-technical with changing conditions requirements. We have surveyed core...

Abstract Based on the results of an extensive market analysis and technology assessment, this paper summarizes state art in web compares it with needs integration hospital information systems. Web intranet have evolved to a core for distributed computing The advantage platform independent distribution has led euphoric visions future integrated However, true takes more than transparent access heterogeneous sources. To overcome essential problems related autonomous systems is important find...

Summary Objectives: To elaborate main system characteristics and relevant deployment experiences for the health information (HIS) Orbis®/ OpenMed, which is in widespread use Germany, Austria, Switzerland. Methods: In a phase of 3 years 1.200 bed university hospital, where underwent significant improvements, system’s functionality its software design have been analyzed detail. We focus on an integrated CASE tool generating embedded clinical applications incremental evolution. present...

Summary Objectives: To analyze and to optimize interdisciplinary clinical processes, introduce an IT-supported model for demand-driven system evolution in healthcare, demonstrate the feasibility of approach a example present evaluation. Methods: System change management are viewed as two sides same coin, thus formal methods process analysis IT were embedded into goal-oriented model. Based on model, Failure Mode Effects Analysis (FMEA) computer simulation performed. A tool rapid application...

Summary Objectives To identify core challenges and first steps on the way to sustainable information systems in healthcare. Methods Recent articles healthcare technology related from Medical Informatics Computer Science were reviewed analyzed. Core that couldn’t be solved over years are identified. Results The two problem areas process integration, meaning effectively embed IT-systems into routine workflows, reduce effort for interconnecting independently developed IT-components. Standards...

Inadequate availability of patient information is a major cause for medical errors and affects costs in healthcare. Traditional integration healthcare does not solve the problem. For chronic diseases multimorbidity, significance yet increasing. Applying document-oriented paradigm to mediated publish-subscribe infrastructure allows foster inter-institutional exchange The goal proposed architecture provide between strict autonomous institutions, bridging gap primary secondary care, following...

In healthcare, inter-institutional process support implicates decentralized and ad-hoc workflows. From the perspective of system integration, autonomy sites which are participating in a healthcare network is mostly untouchable. Traditional activity-oriented workflow models or content-oriented do not provide adequate such environments scenarios. The objective alpha-Flow approach to enable distributed, with initially unknown sets actors institutions. its document-oriented model, electronic...

Inter-institutional collaboration among physicians becomes increasingly important and yet, it’s unrealistic to assume that cooperation can be supported via a homogeneous system which is pre-installed in every organization. Instead will typically have their own autonomous systems support internal processes. Traditional activity-oriented workflow models or content-oriented process do not resolve inter-institutional integration challenges. The authors present the a-Flow approach for distributed...

We present Massive Multiuser Event Infrastructure (M2etis), a configurable publish-subscribe middleware. M2etis uses discrete-event simulations and regression methods to translate declarative descriptions of event types in terms the application domain an optimal configuration. Configuration decisions are based on Quality-of-Service (QoS) requirements conducted by configuration component at design-time minimize performance impacts run-time.
