Arden Syntax: Technical Integration III (July 7, 2014)—Intelligent eHealth solutions often demand technical integration IIIpatient data from different sources such as hospital, laboratory, and intensive care information systems or—out of performance or legal reasons—a strict separation of patient data gathering and intelligent processing is necessary. In these cases, Medexter's Arden Syntax server, including its rule engine and its database connector, accesses a project-specific data warehouse (which can be quite general and extended). This data warehouse receives "raw" patient data through communication servers or import routines from any external data source (in HL7/XML/batch or other formats). The received data trigger the rule engine (when appropriate), and the data warehouse makes data available for further processing in the Arden Syntax server. The data warehouse can in return store the final or even the intermediate results generated by rule processing. These results may subsequently either be transferred back to the calling host application for presentation or—if the data warehouse is part of a separate solution—to the solution's presentation layer. The stored results may be used for reporting and benchmarking, or for data and knowledge mining. By introducing such an architecture, autonomous add-on clinical decision support systems are established. An example is Medexter's Moni system, which monitors and reports on hospital-acquired infections in intensive care units with adult and neonatal patients.

Arden Syntax: Technical Integration II (July 7, 2014)—The second form of interconnecting Medexter's suite of Artechnical integration IIden Syntax software with host systems and external patient data sources is to call MLMs and events through SOAP or RESTful web services, but to access patient data directly from data sources through a so-called server connector (being an add-on to the Arden Syntax server). This server connector can be used to query patient data through SOAP or RESTful web services that are offered by the host system to access its data, or it comes as a database connector that connects directly to a database to access data (e.g., SQL database). In addition, the server connector can also be developed in such a way as to access data in arbitrary formats (e.g., XML). Technically, the server connector is a template for realizing various operable connectors. Examples are (a) the connection of Medexter's Arden Syntax server with the EPIC hospital information system (via web services provided by EPIC), (b) with the VistA system by the Department of Veterans Affairs (again through web services, here provided by VistA), and (c) accessing SQL databases through Medexter's database connector to obtain patient data from routine patient databases or from databases for research (and teaching).

Arden Syntax: Technical Integration I (July 7, 2014)—The Arden Syntax server harbors the Arden Syntax medical logic modules (MLMs). These technical integrationknowledge packages are written, tested, and compiled using the integrated Arden Syntax development environment (IDE). To connect the server with host systems and data sources, Medexter offers three basic forms of technical integration into different health information technology (IT) environments. Using the first form of integration, MLM and event calls are realized by SOAP or RESTful web services, with the respective service also transferring the necessary data required for MLM processing. Examples are (a) the connection between Medexter's Arden Syntax server and Siemens' (Xetra: SIE, NYSE: SI, LSE: SIE, SWX: SIN) hospital information system via SOAP web services, and (b) calling of and providing data for the iPhone and iPad App Hepaxpert via RESTful web services.

Fuzziness in Healthcare-Associated Infection Monitoring (June 25, 2014)—At the Annual Meeting of the North American Fuzzy Information Processing Society (NAFIPS) that was held as part of the IEEE 2014 conference on Norbert Wiener in the 21st Century, our CEO and Scientific Head Prof. Dr. Klaus-Peter Adlassnig presented a paper on "Fuzziness in Healthcare-Associated Infection Monitoring and Surveillance". The paper was co-authored by members of the Medical University of Vienna.

Arden Syntax Lecture, Dortmund (June 5, 2014)—At the Department of Computer Science of the FH Dortmund (University of Applied Sciences and Arts) in Dortmund, Germany, Klaus-Peter Adlassnig, CEO and Scientific Head of Medexter Healthcare, gave overall three well received lectures on different topics: Firstly, an introductory lecture on Arden Syntax, its Fuzzy Logic component, ArdenML, as well as on possible technical integrations, secondly, about clincial decision support in practice, and thirdly, concerning the use of intelligent systems in healthcare and the question of responsibility.

eHealth Summit Austria 2014, Vienna (May 22–23, 2014)In the end of May, the eHealth Summit Austria took place P1040038 rin the picturesque setting of the Schönbrunn Palace in Vienna. Medexter participated in the event as exhibitor as part of the trade fair. Additionally, members of the Medexter Healthcare team contributed to the scientific conference in form of overall 6 lectures. Inspiring discussions about our approach and products as well as promising meetings with prospective customers ensued.

Scientific contributions at eHealth Summit Austria 2014, Vienna (May 22–23, 2014)Univ.-Prof. Dr. Klaus-Peter Adlassnig (CEO) and DI Karsten Fehre (research and development) held a workshop in cooperation with Univ.-Prof. Dr. Michael Binder (Medical University of Vienna) and Mag. Dr. Stefan Sabutsch (ELGA GmbH and head of HL7 Austria) on "HL7-Standards zur medizinischen Wissensverarbeitung: Arden-Syntax und ArdenML". Addressing the topic "mHealth and Telehealth", Dr. Philipp Meng presented a "Framework for Near-Field-Communication-Based Geo-Localization and Personalization for Android-Based Smartphones—Application in Hospital Environments". DI Alexander Seitinger participated in the finale of the conference's student competition with "An Arden-Syntax-Based Clinical Decision Support Framework for Medical Guidelines—Lyme Borreliosis as an Example". Talking about "Monitoring von unerwünschten Arzneimittelwirkungen – für Klinik, Qualitätsmanagement und Pharmakovigilanz", CEO Prof. Dr. Klaus-Peter Adlassnig contributed to the ongoing discussion regarding "Medication Safety". Additionally, a presentation entitled "Towards a Global IT System for Personalized Medicine: The Medicine Safety Code Initiative" was given by Mag. Dr. Matthias Samwald on the topic "eMedication and Drug Safety". The final highlight of Medexter's presentation activities was a software demonstration by CEO Prof. Dr. Klaus-Peter Adlassnig showing the possibilities of "Healthcare-Associated Infection Surveillance and Bedside Alerts" using the surveillance tool Moni (Monitoring of Nosocomial Infections)an application developed by Medexter Healthcare and in use in several hospitals.

Arden Syntax Training, Vienna (May 21, 2014)In cooperation with HL7 Austria, Medexter hosted a one-day Arden Syntax training course at the FH Technikum in Vienna. Attendees were Germans and Austrians who were either interested beginners in the Arden Syntax or were already using it and looking for a more detailed insight into the field. Contents discussed included Arden Syntax, Fuzzy Arden Syntax, ArdenML, software components, technical integration, and clinical applications. Find material here.

Conference on Data Safety in Healthcare, Berlin (May 13, 2014)—At the 2nd GDD-Fachtagung on data safety in healthcare "Datenschutz und Datensicherheit im Gesundheitswesen", CEO Prof. Dr. Klaus-Peter Adlassnig contributed to the discussion regarding the issue of responsibility for intelligent and autonomous IT systems in his lecture "Intelligente und autonome Systeme in der Medizin - Wer trägt die Verantwortung?".

ConhIT 2014, Berlin (May 6–8, 2014)—For the fifth time, Medexter Healthcare attended conhit 2014the Connecting Healthcare IT (conhIT) trade fair in Berlin/Germany. Medexter's clinical decision support products where presented in our booth and interesting conversations as well as intensive discussions with present and prospective customers took place. Additionally, the Medexter booth was part of the guided tour "Interoperability" with focus on applications, where selected exhibitors showed their topic-related IT solutions.
