    Abstract [en]

    Based on some identified problems and challenges to the current healthcare system, this paper proposes architecture for developing e-health system to meet the challenges and resolve some problems. The architecture is based on a solid theoretical model of human activity, and it has properties such as sustainability, generality, and expandability. We demonstrate the properties of the architecture through an ongoing research project. We concluded that this architecture can be widely used to integrate various small scale applications of e-health systems and to resolve some current design problems such as interoperability and knowledge sharing.

    Activity Theory Ontology for Knowledge Sharing in E-health2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    Knowledge sharing has become an imperative and challenging issue in the E-health field for improving total quality of services. However, since the E-health subject is a multi-disciplinary and cross-organizational area, to have shared concepts, vocabulary plus a specification of its intended meaning, namely an ontology, has been an obstacle to develop e-health system. We will in this paper propose a knowledge sharing ontology on the basis of Activity Theory. We believe that Activity Theory can provide high level and rich ontology for the developers of E-health system to encompass the multi-disciplinary and cross-organizational knowledge. We validate our approach in the end by demonstrating our project IMIS (Integrated Mobile Information System for Healthcare) that uses the activity theory as ontological architecture for the construction of the whole system.

    Heterogeneous Knowledge Sharing in eHealth: Modeling, Validation and Application2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Knowledge sharing has become an important issue in the eHealth field for improving the quality of healthcare service. However, since eHealth subject is a multidisciplinary and cross-organizational area, knowledge sharing is a serious challenge when it comes to developing eHealth systems. Thus, this thesis studies the heterogeneous knowledge sharing in eHealth and proposes a knowledge sharing ontology. The study consists of three main parts: modeling, validation and application.

    In the modeling part, knowledge sharing in eHealth is studied from two main aspects: the first aspect is the heterogeneous knowledge of different healthcare actors, and the second aspect is the interactivities among various healthcare actors. In this part, the contribution is to propose an Activity Theory based Ontology (ATO) model to highlight and represent these two aspects of eHealth knowledge sharing, which is helpful for designing efficient eHealth systems.

    In the validation part, a questionnaire based survey is conducted to practically validate the feasibility of the proposed ATO model. The survey results are analyzed to explore the effectiveness of the proposed model for designing efficient knowledge sharing in eHealth. Further, a web based software prototype is constructed to validate the applicability of the ATO model for practical eHealth systems. In this part, the contribution is to explore and show how the proposed ATO model can be validated.

    In the application part, the importance and usefulness of applying the proposed ATO model to solve two real problems are addressed. These two problems are healthcare decision making and appointment scheduling. There is a similar basic challenge in both these problems: a healthcare provider (e.g., a doctor) needs to provide optimal healthcare service (e.g., suitable medicine or fast treatment) to a healthcare receiver (e.g., a patient). Here, the optimization of the healthcare service needs to be achieved in accordance with eHealth knowledge which is distributed in the system and needs to be shared, such as the doctor’s competence, the patient’s health status, and priority control on patients’ diseases. In this part, the contribution is to propose a smart system called eHealth Appointment Scheduling System (eHASS) based on ATO model.

    This research work has been presented in eight conference and journal papers, which, along with an introductory chapter, are included in this compilation thesis.

    Activity Theory based Ontology Model for efficient Knowledge Sharing in eHealth2017Ingår i: E-Health Telecommunication Systems and Networks, ISSN 2167-9517, E-ISSN 2167-9525, Vol. 6, s. 31-45Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Knowledge sharing has become an important issue that challenges the efficient healthcare delivery in eHealth system. It also rises as one of the mostdemanding applications with reference to dynamic interactivities among various healthcare actors (e.g. doctors, nurses, patients, relatives of patients). Inthis paper, we suggest an activity theory based ontology model to represent various healthcare actors. The goal of the suggested model is to enhance inte-ractivities among these healthcare actors for conducting more efficient knowledge sharing, which helps to design eHealth system. To validate the feasibilityof suggested ontology model, three typical use cases are further studied. A questionnaire based survey is carried out and the corresponding survey resultsare reported, together with the detailed discussions.

    A new Software Framework for Heterogeneous Knowledge Sharing in Healthcare system2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    Today’s demand for healthcare is dramatically increasing as the factor of the aging population and expectations growing during the past few years. This leads to the need of substantial healthcare services with innovative technologies developed from both industry and academia. Designing an efficient healthcare system is however a sophisticated process due to different research issues with the requirement for the provision of high-quality healthcare services. Connected to this requirement, the focus of many studies done so far is widely laid on a well-known problem called knowledge sharing. In recent years, knowledge sharing raises as one of the most demanding applications with references to the dynamic inter-activity among different healthcare actors and the complex data structures involved in this application. Suitable solution approach to knowledge sharing can enhance the efficiency of healthcare delivery, and thus improving the quality of healthcare services. The corresponding development tasks can be accomplished by using different methodologies such as analytical approaches, simulation experiments and practical measurements on the real healthcare system.In our work, the problem of heterogeneous knowledge sharing in the healthcare system is considered. Here, the heterogeneous aspect is expressed in terms ofdifferent healthcare actors and the associated characterizations. To do this, we suggest a new software framework, which mainly consists of three components. The first component is about the ontology based activity theory, which is used to scientifically represent the healthcare actors together with their relationships and interactions. The second component refers to an overlay decision maker, which is responsible for dealing with the decision-making activities such as appointment scheduling. Its advantage is to jointly consider various healthcare parameters and different algorithms for decision-making purposes. Based on these two components, the third component provides the theoretical models to conduct the numerical analysis and performance evaluation on the particular healthcare service.

    Using P2P Technology to Achieve eHealth Interoperability2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    Abstract—eHealth is an emerging area that boosts up with advancement in Information and Communication Technology (ICT). Due to variety of eHealth solutions developed by different IT firms with no unified standards, interoperability issue has raised. In this paper, a case study in Blekinge County healthcare organizations has been conducted for understanding the contexts of eHealth interoperability issues. Then a peer-to-peer (P2P) model based on JXTA platform is implemented to solve the identified eHealth interoperability problems. According to the test result of the prototype, the suggested syntactic level interoperability among healthcare organizations has been achieved.

    On Performance of Prioritized Appointment Scheduling for Healthcare2017Ingår i: TRANSACTIONS ON EMERGING TELECOMMUNICATIONS TECHNOLOGIESArtikel i tidskrift (Refereegranskat)
    Abstract [en]

    Designing the appointment scheduling is a challenging task for the development of healthcare system. The efficient solution approach can provide high quality of healthcare service between care providers (CP) s and care receivers (CR) s. In this paper, we consider the healthcare system with the heterogeneous CRs in terms of urgent and routine CRs. Our suggested model assumes that the system gives the service priority to the urgent CRs by allowing them to interrupt the ongoing routine appointments. An appointment handoff scheme is suggested for the interrupted routine appointments, and thus the routine CRs can attempt to re-establish the appointment scheduling with other available CPs. With these considerations, we study the scheduling performance of the system by using Markov chains based modeling approach. The numerical analysis is reported and the simulation experiment is conducted to validate the numerical results.

    eHASS: A Smart Appointment Scheduling System for eHealth2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    In the eHealth system, the appointment scheduling is an important task for the delivery of healthcare service among different healthcare actors. The key procedure is to do the decision making on the selection of suitable appointments between the care providers and the care receivers. The appointment decisionis a sophisticated problem in terms of how to efficiently deal with various parameters of involved healthcare actors. To solve this problem, we suggest a smart system called eHealth Appointment Scheduling System (eHASS). eHASS takes into account both heterogeneous aspects and interoperability requirements of eHealth system. As such, eHASS is capable of jointly considering various appointment characterizations and decision making algorithms for conducting appointment scheduling. The paper reports the eHASS architecture as well as the related work-in-progress.
