    AbstractCanadian healthcare is a fundamental part of society. Challenges such as the aging baby boomer generation require the healthcare industry to meet higher demands while using fewer resources. Computer systems designed to record and report physical health properties of an individual personcan be used in part to accomplish this task. In this paper, we present the architecture of a hypothetical multi-agent system designed to provide healthcare information about specific patients through continuous monitoring. The resulting data from the system is accessible by the patient to whom it belongs as well as his or her healthcare professional. Furthermore, the proposed system utilizes an adaptive user interface for the purpose of improving the overall experience for users with poor vision or motor skills. Specifically, we focus on the implementation of several of the key components involved in the adaptive user interface: learning component and the user model. To demonstrate the feasibility of the implementation two scenarios are provided. We conclude with several possible future directions for this research

    In this work, an automatic and intelligent system for integrated healthcare processes management is developed on a constraint based system. This project has been carried out in collaboration with a real assisted repro-duction clinic. Our goal is to improve the efficiency of the clinic by facilitating the management of the integrated healthcare system. This is very important in an environment in which the healthcare processes present complex temporal and resource constraints.Ministerio de Economía y Competitividad TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED

    Measurement system for the evaluation of alternating pressure redistribution mattresses using pressure relief index and tissue perfusion – a preliminary study

    Get PDF
    Clinicians who are selecting dynamic support surfaces such as alternating pressure redistribution mattresses (APRMs) for the prevention and treatment of pressure ulcers are faced with commercial literature that predominantly reports on magnitudes of interface pressures, rather than on additional parameters. The aim of this preliminary study was to generate a pressure relief index (PRI) to evaluate dynamic support surfaces using the magnitude of interface pressures as well as their duration. Data for generating a PRI were captured from 11 subjects on two different dynamic support surfaces using three different, arbitrarily selected, interface pressure thresholds. Tissue perfusion measurements were used to evaluate the reliability of the calculated PRI. The results demonstrate a good relationship (r=0.7) between PRI and tissue perfusion values. The generated PRI appears to be a reliable indicator of the recovery time allowed below a given interface pressure and is therefore a useful parameter for selecting appropriate dynamic support surfaces

    Design and implementation of a secure and user-friendly broker platform supporting the end-to-end provisioning of e-homecare services

    We designed a broker platform for e-homecare services using web service technology. The broker allows efficient data communication and guarantees quality requirements such as security, availability and cost-efficiency by dynamic selection of services, minimizing user interactions and simplifying authentication through a single user sign-on. A prototype was implemented, with several e-homecare services (alarm, telemonitoring, audio diary and video-chat). It was evaluated by patients with diabetes and multiple sclerosis. The patients found that the start-up time and overhead imposed by the platform was satisfactory. Having all e-homecare services integrated into a single application, which required only one login, resulted in a high quality of experience for the patients

    Using System Analysis and Personas for e-Health Interaction Design

    Today, designers obtain more central roles in product and service development (Perks, Cooper, & Jones, 2005). They have to deal with increasingly complicated problems, like integrating the needs of various stakeholders while taking care about social, ethical and ecological consequences of their designs. To deal with this demanding design situation, they need to apply new methods to organize the available information and to negotiate the stakeholder’s perspectives. This paper describes how systems analysis supports the design process in a complex environment. In a case study, we demonstrate how this method enables designers to describe user requirements for complex design environments while considering the perspectives of various stakeholders. We present a design research project applying cybernetic systems analysis using the software ''System-Tools'' (Vester, 2002). Results from the analysis were taken to inform the design of an electronic patient record (EPR), considering the particularities of the German health care system. Based on the analysis, we developed a set of requirements for every stakeholder group, detailing the patients' perspective with persona descriptions. We then picked a main persona as reference for the EPR design. We describe the resulting design sketch and discuss the value of cybernetic systems analysis as a tool to deal with complex social environments. The result shows how the method helps designers to structure and organize information about the context and identify fruitful intervention opportunities for design.

    User-centered visual analysis using a hybrid reasoning architecture for intensive care units

    Get PDF
    One problem pertaining to Intensive Care Unit information systems is that, in some cases, a very dense display of data can result. To ensure the overview and readability of the increasing volumes of data, some special features are required (e.g., data prioritization, clustering, and selection mechanisms) with the application of analytical methods (e.g., temporal data abstraction, principal component analysis, and detection of events). This paper addresses the problem of improving the integration of the visual and analytical methods applied to medical monitoring systems. We present a knowledge- and machine learning-based approach to support the knowledge discovery process with appropriate analytical and visual methods. Its potential benefit to the development of user interfaces for intelligent monitors that can assist with the detection and explanation of new, potentially threatening medical events. The proposed hybrid reasoning architecture provides an interactive graphical user interface to adjust the parameters of the analytical methods based on the users' task at hand. The action sequences performed on the graphical user interface by the user are consolidated in a dynamic knowledge base with specific hybrid reasoning that integrates symbolic and connectionist approaches. These sequences of expert knowledge acquisition can be very efficient for making easier knowledge emergence during a similar experience and positively impact the monitoring of critical situations. The provided graphical user interface incorporating a user-centered visual analysis is exploited to facilitate the natural and effective representation of clinical information for patient care

    Accessing Patient Records in Virtual Healthcare Organisations

    No full text
    The ARTEMIS project is developing a semantic web service based P2P interoperability infrastructure for healthcare information systems that will allow healthcare providers to securely share patient records within virtual healthcare organisations. Authorisation decisions to access patient records across organisation boundaries can be very dynamic and must occur within a strict legislative framework. In ARTEMIS we are developing a dynamic authorisation mechanism called PBAC that provides a means of contextual and process oriented access control to enforce healthcare business processes. PBAC demonstrates how healthcare providers can dynamically share patient records for care pathways across organisation boundaries
