Interactive tele-radiological segmentation systems for treatment and diagnosis

Author: Dr. L. Gortzis

Telehealth is the exchange of health information and the provision of health care services through electronic information and communications technology, where participants are separated by geographic, time, social and cultural barriers. The shift of telemedicine from desktop platforms to wireless and mobile technologies is likely to have a significant impact on healthcare in the future.

Estimating the success of e-health collaborative services: the THEMIS framework

Author: Dr. L. Gortzis

This study proposes a prototype framework (THEMIS) for estimating algebraically the success (S) of the electronic health collaborative services (e-HCS) and examines two hypotheses: first, that the S estimation of an e-HCS, developed by a third-party vendor, demands a ‘shrunk formative model’ and second that causal relationships between the involved dimensions (FFP, CO, COSTS) do exist, and their parameters affect the S – from weakly to strongly and vice-versa.

Coordinating effectively a heart attack pre-hospital service process using constraint optimization programming

Author: C. Pylarinou Author: Dr. L. Gortzis Author: S. Zimeras

The most crucial factor when dealing with heart attack incidents is the fast and accurate diagnosis and pre hospital service of the patient. Considering the need of handling time efficiently, emphasis is paid on the interval time management starting from the moment the incident is recognized up to the time the patient is in an emergency unit.

Selecting Healthcare Information Systems Provided By Third-Party Vendors: A Mind Map Beyond The Manuals

Author: Dr. L. Gortzis

The selection of a new healthcare information system (HIS) has always been a daunting process for clinicians, health care providers and policy makers. The objective of this study is to present the lessons learned and the main findings from several relevant case studies to support this process.

e-Health: Are there expert patients out there?

Author: Dr. L. Gortzis

The patients' ability to perform healthcare measurements by themselves using the information communication technologies (ICT) is a valuable variable. But are there 'expert patients' out there? The objective of the present study is to address this question. In Scenario A, participants performed measurements themselves using a portable biosignal device (PBD) in 'bedside settings'.

Investigating the prognostic accuracy of standardized data mining algorithms in Intensive Care Unit

Author: Dr. L. Gortzis et al.

Modern clinicians use scalable data mining models to evaluate their hypotheses. The purpose of this paper is to present the lessons learned in solving prognostic problems in Intensive Care Unit (ICU) by using data mining models developed with standardized algorithms as an alternative solution to clinical assessment tools.

Predicting ICU survival: A meta-level approach

Author: Dr. L. Gortzis et al.

The performance of separate Intensive Care Unit (ICU) status scoring systems vis-à-vis prediction of outcome is not satisfactory. Computer-based predictive modeling techniques may yield good results but their performance has seldom been extensively compared to that of other mature or emerging predictive models.

Tracing and cataloguing knowledge in an e-health cardiology environment

Author: Dr. L. Gortzis

In an e-health cardiology environment, the current knowledge engineering systems can support two knowledge processes; the knowledge tracing, and the knowledge cataloguing. We have developed an n-tier system capable of supporting these processes by enabling human collaboration in each phase along with, a prototype scalable knowledge engineering tactic. A knowledge graph is used as a dynamic information structure. Biosignal data (values of HR, QRS, and ST variables)

Portable biomedical devices: a critical issue during telecare services design

Author: Dr. L. Gortzis et al.

The selection of a portable biomedical device (PBD) is a key issue regarding telecare service design. The objective of this study is to investigate the accuracy parameters of a PBD under different settings and levels. By using a commercial PBD, trials were performed in a referral cardiology center and on the Olympia Explorer of the Royal Olympia Cruises, and the Superfast XII of Superfast Ferries.

Collaborative work during interventional radiological procedures based on a multicast satellite-terrestrial network

Author: Dr. L. Gortzis et al.

Collaboration is a key requirement in several contemporary interventional radiology procedures (IRPs). This work proposes a multicast hybrid satellite system capable of supporting advanced IRP collaboration, and evaluates its feasibility and applicability. Following a detailed IRP requirements study, we have developed a system which supports IRP collaboration through the employment of a hybrid satellite-terrestrial network, a prototype multicast version of wavelet based interactive communication system

Clinical Teleradiology: Collaboration over the Web During Interventional Radiology Procedures

Author: Dr. L. Gortzis

Web-based collaborative clinical teleradiology can be looked upon as a set of services for quality assurance that enables expertise sharing and furthers health education opportunities. In particular, this set of services is a requisite of optimizing the final outcomes: structuring a common collaborative educational basis able to connect simultaneously

Optimizing the interventional cardiology facility: services integration in routine workflowy

Author: Dr. L. Gortzis et al.

Integration of administrative and clinical data, imaging, and expert services, although challenging,is a key requirement in contemporary interventional cardiology facilities (ICF). We propose a workflow-oriented hybrid system to support the ICF and investigate its feasibility and effectiveness in a referral medical center. We have developed a Java-powered hybrid system (NetCARDIO), able to support over web synchronous and asynchronous data management, real time multimedia data telemonitoring and continuous telementoring.

Designing and redesigning medical telecare services: a forces-oriented model

Author: Dr. L. Gortzis

Medical telecare services' designing and redesigning still remains a challenging issue since it often depends on how a number of socio-technological issues are framed. This work has two key objectives; the former is to theoretically analyze the nature of a telecare environment by developing a model that reveals potential areas of analysis and the latter is to support designing and redesigning medical telecare services by formulating a strategy as well as a number of 'state of the art' guidelines.

Clinical-Oriented Collaboration Over the Web During Interventional Radiology Procedures

Author: Dr. L. Gortzis

Multidisciplinary collaboration is a key requirement in several contemporary interventional radiology procedures (IRPs). We proposed a hybrid system (NetAngio) to enable "on the fly” heterogeneous collaboration to support IRP providing intraoperating essential services, and investigate its feasibility and effectiveness in a referral medical center. We have developed a Web-based, cost-effective structure, able to support real-time mentoring, image manipulation, and education services beyond the boundaries.

Design and implementation of a web-enabled haematological system

Author: Dr. L. Gortzis

This work describes the design and the implementation of a web-enabled integrated haematological system, named e-HS. The proposed system runs on a set of distributed network nodes providing useful haematological services. These services include patient-oriented data management, digitized histopathological slides (DHS) acquisition, teleconsulting facilities, etc.The objective of e-HS is to supply web-enabled services according to haematological requirements, implement a distributed storage scheme for DHS, and provide a common database containing all haematological laboratory results by using eXtensible Markup Language (XML) and web technologies.

Tele-diagnostic and Therapeutic Guidance in Urology

Author: Dr. L. Gortzis

To design a Web-based network for diagnostic and therapeutic guidance in urology.We designed an architectural model of a low-cost multimedia Web platform that runs on a collection of distributed collaborative network nodes to provide a set of urologist-oriented Web-enabled services. Any node of the platform was able to share patient-oriented data via automated processes with appropriate authorization, confidentiality, and high-security protocols.
