Study Shows Time Savings for Medical Experts Due to Moni-ICU Surveillance (October 15, 2009)—A first, small accuracy and impact study on Moni/Surveillance-ICU, our software for the early identification and continuous monitoring of hospital-acquired infections in intensive care units (ICUs), was carried out. The HELICS-based definitions of the various episodes of infection were evaluated by both human infection control experts and automated Moni/Surveillance-ICU computations. This was done for 99 patients with a total of 1007 patient days. Specificity was 100% and sensitivity 90.3%. There are still some data import and rule definition problems through non-digitizable medical data, but overall time savings for the medical specialists was almost 85% (a total of 70 h). To be presented at the 13th World Congress on Medical and Health Informatics MEDINFO 2010, 12 to 15 September 2010, Cape Town, South Africa.

Arden-Syntax-Based CDS Software with Service-Oriented Architecture (SOA) (October 15, 2009)—Medexter Healthcare announces the completion of its Arden-Syntax-based clinical decision support software with SOA. In its core, it contains an Arden Syntax compiler and an Arden Syntax engine. In order to communicate with host medical information systems (in the broadest sense), an Arden Syntax server programmed in Java encapsulates the engine and provides interfaces for a well-defined communication (e.g., SOAP, REST, XML, or HL7) to the outside, which includes incoming and outgoing requests.

Processing Gradual Information with Fuzzy Arden Syntax (October 15, 2009)—A report on "Processing gradual information with Fuzzy Arden Syntax" with examples from clinical decision support was prepared and will be presented at the 13th World Congress on Medical and Health Informatics MEDINFO 2010, 12 to 15 September 2010, Cape Town, South Africa.

Monitoring of Hospital-Acquired Infections in ICUs, Vienna General Hospital (October 6, 2009)—Medexter Healthcare put into operation its latest Moni/Surveillance-ICU software for identification and monitoring of hospital-acquired infections in adult patients at intensive care units (ICUs) of the Vienna General Hospital/Medical University of Vienna (AKH Wien/MUW). This software replaces the Moni-IV system that has been running since July 2007. Like its counterpart for neonatal ICUs, it accesses patient care data collected by the installed Philips CareVue intensive-care medical information systems at the connected 12 ICUs (96 beds). The software monitors the incoming routine data for signs of hospital-acquired blood stream infections, ICU-acquired pneumonias, urinary tract infections, and central venous catheter-related infections, and provides the infection control personnel of the Vienna General Hospital with the results. Technically, Moni/Surveillance-ICU is based on web-services made available in the AKH Wien-wide intranet, and on an extended knowledge base, implemented in form of Arden Syntax medical logic modules (MLMs), extended by fuzzy set and fuzzy logic methods. The cockpit surveillance application allows detailed case-specific interactive analyses of the detected results. The results are updated routinely every day, but may by renewed on request if an epidemic situation calls for close monitoring.

Monitoring of Hospital-Acquired Infections in NICUs, Vienna General Hospital (October 2, 2009)—Medexter Healthcare puts into operation its recently developed Moni/Surveillance-NICU software for the automated, knowledge-based identification and monitoring of hospital-acquired infections at the neonatal intensive care units (NICUs) of the Vienna General Hospital/Medical University of Vienna, Austria (AKH Wien/MUW). This software is connected to the Philips CareVue intensive-care medical information systems at the three NICUs (36 beds) of the Department of Pediatrics and Adolescent Medicine of the AKH Wien/MUW, where it keeps various forms of blood stream infections and ICU-acquired pneumonias under surveillance. Technically, Moni/Surveillance-NICU is based on web-services, made available in the AKH Wien-wide intranet, and on an extended knowledge base, implemented in form of Arden Syntax medical logic modules (MLMs), extended by fuzzy set and fuzzy logic methods. The results are provided to both the infection control personnel of the Department of Pediatrics and Adolescent Medicine and the infection control unit of the Vienna General Hospital; a cockpit-like, interactive access allows for detailed patient case analyses on a real-time, daily basis.

Fuzziness in the Arden Syntax (September 22, 2009)—Medexter Healthcare partners with the Arden Syntax Special Interest Group (SIG) of Health Level Seven (HL7), thereby extending Arden Syntax to Fuzzy Arden Syntax, developed by Medexter. The commonly decided timeline aims at including Fuzzy Arden Syntax into one of the next Arden Syntax versions, tentatively in 2011.

Arden Syntax Special Interest Group of HL7, Atlanta (September 22, 2009)—The Arden Syntax Special Interest Group (SIG) of Health Level Seven (HL7) welcomed Medexter Healthcare’s commentaries on the Arden Syntax versions 2.5, 2.6, and 2.7 during its meeting at the 23rd Annual Plenary and Working Group Meeting of HL7 in Atlanta, GA, U.S.A. The results of this analysis will be incorporated into future Arden Syntax specifications.

Research Project: Arden Syntax Software and Dräger's ICM System, Erlangen (September 9, 2009)—Within a joint research project with Dräger Medical AG & Co. KG, the Department for Medical Informatics at the University of Erlangen, Germany, ordered a license and support package of the medexter-Arden Syntax rule engine software for research and teaching purpose. Part of the intended work is the interconnection of Dräger’s critical care information management system ICM (intensive care manager) with Medexter’s Arden Syntax software to achieve high-level decision support functionality.

International Conference on Medical Informatics Europe MIE 2009, Sarajevo (September 4, 2009)—Our CEO and Scientific Head, Professor Klaus-Peter Adlassnig, acted as the Scientific Program Chair of the XXII International Conference on Medical Informatics Europe MIE 2009 that was held in Sarajevo, Bosnia and Herzegovina, from 30 August to 2 September 2009. The conference included 171 scientific oral and 21 poster presentations, 5 tutorials, 16 workshops, and 9 keynote lectures, and attracted about 400 participants from 38 different countries. The scientific topics presented there ranged from national and trans-national eHealth roadmaps, health information and electronic health record systems, systems interoperability and communication standards, medical terminology and ontology approaches, and social networks to Web, Web 2.0, and Semantic Web solutions for patients, health personnel, and researchers. Furthermore, they included quality assurance and usability of medical informatics systems, specific disease management and telemedicine systems, drug safety, clinical decision support and medical expert systems, clinical practice guidelines and protocols, as well as issues on privacy and security. Moreover, bioinformatics, biomedical modeling and simulation, medical imaging and visualization and, last but not least, learning and education through medical informatics systems were part of the included topic areas.

Arden Syntax Version 2.7 Implemented (August 7, 2009)—Shortly after the successful upgrade to Arden Syntax version 2.6, Medexter Healthcare announces the completion of implementation of HL7's Arden Syntax version 2.7. This version features an enhanced assignment operator to allow assignment to individual elements in a list and nested attributes in objects. In addition, the object initialization statement has been enhanced to support assigning to named attributes. Corrections/updates to features introduced in previous versions and a reorganization of the evoke slot chapter are also included. The Arden Syntax compiler by Medexter is now able to process Arden Syntax MLMs written in Arden Syntax versions 2.1, 2.5, 2.6, and 2.7.
