    ABSTRACT: The modeling of clinical guidelines in order to apply them in computerized medical tools is a challenging and laborious task. In this project we show that conditional subordination links - a temporal relation concept of TimeML - can be used to describe condition-based activities in a guideline. Therefore, we extend the specification of TimeML concerning events and subordination links. Subsequently, linguistic and semantic rules are developed to automatically generate annotations for these links and classify them as relevant for the clinical care path. Finally, the evaluation of the method shows that this categorization supports the task of the guideline modeling expert.

    ABSTRACT: Timely feedback on surgical technique is an important aspect of surgical skill training in any learning environment, be it virtual or otherwise. Feedback on technique should be provided in real-time to allow trainees to recognize and amend their errors as they occur. Expert surgeons have typically carried out this task, but they have limited time available to spend with trainees. Virtual reality surgical simulators offer effective, repeatable training at relatively low cost, but their benefits may not be fully realized while they still require the presence of experts to provide feedback. We attempt to overcome this limitation by introducing a real-time feedback system for surgical technique within a temporal bone surgical simulator. Our evaluation study shows that this feedback system performs exceptionally well with respect to accuracy and effectiveness.

    ABSTRACT: Significant improvements in the field of diagnostic methods and therapeutic options achieved during the last decade allow the early diagnosis, accurate follow-up and individual indication for the treatment with highly efficacious therapeutic agents in a wide range of ophthalmological pathologies. The burden on health care systems is extremely high, as treatment and diagnostic follow up has to be repeated in a regular manner. Whereas the treatment can only be applied in tertiary care centers (eye clinics), follow-up and management mainly depends on the OCT technology, which is becoming available at many field ophthalmologists' practices. This article describes the OphthalNet project, a network which optimizes collaboration between eye clinics and field ophthalmologists based on medical guidelines, workflow support and the future use of electronic infrastructure.

    ABSTRACT: Natural Orifice Translumenal Endoscopic Surgery is an emerging procedure that requires training and adoption to be successful. Currently no objective performance metrics exist for evaluating skills for NOTES. In this work, we have improved upon our previous study on objective performance metrics using kinematic measures by introducing two new measures, the flex and the roll and recruiting more subjects to increase the statistical power. The measures were evaluated in a transgastric NOTES appendectomy procedure performed with ex-vivo organs using the EASIE-R<sup>TM</sup> trainer box. Four motion tracking sensors attached to an endoscope were used to measure the scope position and orientation to compute the kinematic measures. Results from our study showed that completion time, economy of motion, jerk and roll of the scope are valid kinematic measures to differentiate between expert and novice NOTES surgeons.

    ABSTRACT: Dealing with data from different source domains is of increasing importance in today's large scale biomedical research endeavours. Within the European Network for Cancer research in Children and Adolescents (ENCCA) a solution to share such data for secondary use will be established. In this paper the solution arising from the aims of the ENCCA project and regulatory requirements concerning data protection and privacy is presented. Since the details of secondary biomedical dataset utilisation are often not known in advance, data protection regulations are met with an identity management concept that facilitates context-specific pseudonymisation and a way of data aggregation using a hidden reference table later on. Phonetic hashing is proposed to prevent duplicated patient registration and re-identification of patients is possible via a trusted third party only. Finally, the solution architecture allows for implementation in a distributed computing environment, including cloud-based elements.

    ABSTRACT: Situation awareness (SA) is a critical non-technical skill which affects outcome during emergency medical endeavors. Using a modified self-report instrument a significant increase of SA was found during multiplayer virtual world CPR team training among 12 medical students. Further a correlation between SA and attention was noted. Being a vital factor during the process of video-game play, we argue that this skill is suitably practiced using this training method.

    ABSTRACT: There are several intra-operative use cases which require the surgeon to interact with medical devices. We used the Leap Motion Controller as input device and implemented two use-cases: 2D-Interaction (e.g. advancing EPR data) and selection of a value (e.g. room illumination brightness). The gesture detection was successful and we mapped its output to several devices and systems.

    ABSTRACT: The paper describes the first, preclinical evaluation of a dietary logging application developed at the University of Pannonia, Hungary. The mobile user interface is briefly introduced. The three evaluation phases examined the completeness and contents of the dietary database and the time expenditure of the mobile based diet logging procedure. The results show that although there are substantial individual differences between various dietary databases, the expectable difference with respect to nutrient contents is below 10% on typical institutional menu list. Another important finding is that the time needed to record the meals can be reduced to about 3 minutes daily especially if the user uses set-based search. Conclusion: a well designed user interface on a mobile device is a viable and reliable way for a personalized lifestyle support service.

    ABSTRACT: Providing real-time, interactive immersive surgical training has been a key research area in telemedicine. Earlier approaches have mainly adopted videotaped training that can only show imagery from a fixed view point. Recent advances on commodity 3D imaging have enabled a new paradigm for immersive surgical training by acquiring nearly complete 3D reconstructions of actual surgical procedures. However, unlike 2D videotaping that can easily stream data in real-time, by far 3D imaging based solutions require pre-capturing and processing the data; surgical trainings using the data have to be conducted offline after the acquisition. In this paper, we present a new real-time immersive 3D surgical training system. Our solution builds upon the recent multi-Kinect based surgical training system [1] that can acquire and display high delity 3D surgical procedures using only a small number of Microsoft Kinect sensors. We build on top of the system a client-server model for real-time streaming. On the server front, we efficiently fuse multiple Kinect data acquired from different viewpoints and compress and then stream the data to the client. On the client front, we build an interactive space-time navigator to allow remote users (e.g., trainees) to witness the surgical procedure in real-time as if they were present in the room.

    ABSTRACT: This work presents a pWeb - a new language and compiler for parallelization of client-side compute intensive web applications such as surgical simulations. The recently introduced HTML5 standard has enabled creating unprecedented applications on the web. Low performance of the web browser, however, remains the bottleneck of computationally intensive applications including visualization of complex scenes, real time physical simulations and image processing compared to native ones. The new proposed language is built upon web workers for multithreaded programming in HTML5. The language provides fundamental functionalities of parallel programming languages as well as the fork/join parallel model which is not supported by web workers. The language compiler automatically generates an equivalent parallel script that complies with the HTML5 standard. A case study on realistic rendering for surgical simulations demonstrates enhanced performance with a compact set of instructions.

    ABSTRACT: The aim of this study is to investigate modelling- and visualisation methods and tools for transparent, reproducible and comprehensible information management of patient probabilistic graphical models such as Multi-Entity Bayesian Networks (MEBN). In therapy planning environments, models provide the knowledge base to assist physicians in their decision making process and are typically at the heart of a networked information system. The topic of user interface design (UID) and specifically GUIs needs to be addressed in this context in a very creative manner, if the aim is to make complex models easier for the user to understand and to manage. As a basis for preparing a demonstration to show a proof of concept for the visualisation of MEBNs, the visualization tool called "ANTz" is being proposed here and used as the preferred visualisation tool.

    ABSTRACT: The PATIENT manikin (Physical Anatomical Trainer Instrumented for Education and Non-subjective Testing) is designed with the conflicting needs of a highly modular system for ultimate scenario flexibility and cost containment, and a highly realistic system. PATIENT provides a unique combination of capital and disposable components, with each organ treated as a limited-reuse component. The organs contain unobtrusive instrumentation which informs the PATIENT control unit of the organ status. The control unit can adjust whole-body parameters to reflect the local physiology. PATIENT enables tailored simulations, from Point of Injury training of basic life support, through hospital training including surgical interventions.

    ABSTRACT: Our understanding and use of simulation based training has evolved from simply practicing or learning performance in an accurate re-creation of the operating room as first envisaged by anaesthetist simulation pioneers. The efficacy of simulation training has been quantitatively demonstrated in prospective, randomized, double blinded studies. Simulation training models used in these studies have varied from bespoke models for training intra-corporeal suturing skills, VR emulation models for basic laparoscopic skill acquisition through to full physics VR simulations for the learning of endovascular skills. The understanding of why specific simulation models are effective needs to be better understood by trainers, researchers and engineers if simulation based training is to deliver on its potential for more advanced skills training but more importantly for the acquisition of procedural wisdom. This development will require a better understanding and more forthright approach to the issue of simulation fidelity.

    ABSTRACT: Introduction/Background: Health information exchange (HIE) is the secure, electronic transfer and/or accessibility of clinical data among healthcare providers. In the United States (US), the consent process for participation varies state to state. New York State (NYS) mandates written patient consent. The purpose of this study was to examine workflow and perceptions related to obtaining HIE consent in an HIV clinic. Methods: We used contextual inquiry to observe the HIE consent-related workflow of four registration clerks for a total of 4 hours on two weekdays and subsequently created a flow chart and sequence model diagram. Clerks were also interviewed and the resulting narrative data were coded into themes. Results: Observational and interview data suggested that patient privacy/confidentiality/trust, high volume workflow, and multiple competing demands affect the patient HIE consent process. Conclusions: Additional qualitative data needs to be gathered from the perspectives of patients and clinicians about the HIE consent process.

    ABSTRACT: Although ICT-enabled clinical practices have been widely accepted by the Western medical society, informatics applications for traditional Chinese medicine (TCM) are under developed. An integrated traditional Chinese medicine clinical practice support system (TCMCPSS) has been developed to enhance data integration automation and treatment planning decision support of clinical practice of TCM. The acceptance of TCMCPSS had been assessed by 26 TCM physicians based on information clarity, clinical relevancy, and theoretical relevancy through a survey questionnaire using the 5-points Likert Scale. The average acceptance rate was 3.76. One hundred and fifty-four participants were recruited for the TCMCPSS feasibility study and reported the acceptance rate of 90%. The results indicated that while consumers were ready to embrace TCM practice assisted by informatics technologies, TCM physicians concerned more about the usefulness of the system and preserved caution to adopt TCMCPSS.

    ABSTRACT: Health self-management is important in the care of patients with chronic kidney disease. It is possible to improve the efficiency of patient self-management through the use of mobile technology and related software. This study is divided into three stages: 1. analysis of need: through observation, interview and content analysis of the chronic kidney disease health management manual; 2. design of system prototype: establish interface and system function; 3. prototype evaluation: evaluate whether the prototype designed by this study meets user needs. The system prototype includes: daily record, laboratory examination results, trend graphs, information search, sharing, communications and settings. Prototyping is done with Pencil Project for interface design and linking. The prototype is then exported in PDF format for mock-up simulation. Evaluation results: overall score was 4.01±0.60 leaning towards "agree", the highest score was ease of use (4.25±0.6), followed by easy to learn (4.15±0.68), acceptance (4.01±0.61), reliability (3.87±0.6) and functionality (3.83±0.49). The results show positive attitude towards the system.

    ABSTRACT: The objective of this study is to propose a Cloud Computing based platform for sleep behavior and chronic disease collaborative research. The platform consists of two main components: (1) a sensing bed sheet with textile sensors to automatically record patient's sleep behaviors and vital signs, and (2) a service-oriented cloud computing architecture (SOCCA) that provides a data repository and allows for sharing and analysis of collected data. Also, we describe our systematic approach to implementing the SOCCA. We believe that the new cloud-based platform can provide nurse and other health professional researchers located in differing geographic locations with a cost effective, flexible, secure and privacy-preserved research environment.

    ABSTRACT: Patients today are demanding greater access to and control of their health information. Personal Health Records (PHRs) are paving the way for patients to update, maintain and share their comprehensive medical information. The opportunity to develop and maintain a PHR is equally as important for those individuals in the disabled community who face many unique challenges to access health information. The project, conducted as part of our graduate course, explored the use of Second Life to educate the disabled community on Virtual Ability Island (VAI) about the importance of PHRs. The project examined the tools needed to offer such a presentation for the disabled community and identified legal, ethical, social, or public challenges for PHR use. The project outcomes indicated a desire for knowledge and genuine concerns by the attendees regarding PHRs. The authors note that more research is needed to make this technology available to all.
