Analysis of QoS Requirements for e-Health Services and Mapping to Evolved Packet System QoS Classes

E-Health services comprise a broad range of healthcare services delivered by using information and communication technology. In order to support existing as well as emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. In this paper, we evaluate the QoS support for e-Health services in the context of the Evolved Packet System (EPS), specified by the Third Generation Partnership Project (3GPP) as a multi-access all-IP NGN. We classify heterogeneous e-Health services based on context and network QoS requirements and propose a mapping to existing 3GPP QoS Class Identifiers (QCIs) that serve as a basis for the class-based QoS concept of the EPS. The proposed mapping aims to provide network operators with guidelines for meeting heterogeneous e-Health service requirements. As an example, we present the QoS requirements for a prototype e-Health service supporting tele-consultation between a patient and a doctor and illustrate the use of the proposed mapping to QCIs in standardized QoS control procedures

Fall Prediction and Prevention Systems: Recent Trends, Challenges, and Future Research Directions.

Fall prediction is a multifaceted problem that involves complex interactions between physiological, behavioral, and environmental factors. Existing fall detection and prediction systems mainly focus on physiological factors such as gait, vision, and cognition, and do not address the multifactorial nature of falls. In addition, these systems lack efficient user interfaces and feedback for preventing future falls. Recent advances in internet of things (IoT) and mobile technologies offer ample opportunities for integrating contextual information about patient behavior and environment along with physiological health data for predicting falls. This article reviews the state-of-the-art in fall detection and prediction systems. It also describes the challenges, limitations, and future directions in the design and implementation of effective fall prediction and prevention systems

Cognitive assisted living ambient system: a survey

The demographic change towards an aging population is creating a significant impact and introducing drastic challenges to our society. We therefore need to find ways to assist older people to stay independently and prevent social isolation of these population. Information and Communication Technologies (ICT) provide various solutions to help older adults to improve their quality of life, stay healthier, and live independently for a time. Ambient Assisted Living (AAL) is a field to investigate innovative technologies to provide assistance as well as healthcare and rehabilitation to impaired seniors. The paper provides a review of research background and technologies of AAL

Telemedicine for improving access to health care in resource-constrained areas : from individual diagnosis to strengthening health systems

In many developing countries there is an acute shortage of trained medical specialists. This does not only hamper individual patients’ access to medical diagnostics but furthermore limits the development of health systems because a major role of the specialists is the provision of continuous medical education of health care personnel. The rapid development of information and communication technologies has enabled radically new forms of virtual collaboration at a distance. So-called telemedicine enables us today to transmit knowledge to the patient rather than to only transport patients to the centres where the knowledge is available; this has promising implications in particular for remote and under-served areas. Initiated by a request from a Swiss surgeon from Solomon Islands, a project for supporting the hospital in Honiara, capital of Solomon Islands, with pathology diagnoses was started between Honiara and the Department of Pathology in Basel in 2001. After a successful start this pilot project found broad interest, and the Internet platform that had been developed was soon utilised by projects from other countries and medical disciplines. Thus, questions arose about the diagnostic accuracy of such remote diagnoses as well as about their acceptance and impact on the local health care system. The work presented here was initiated on this background. It analyses the applicability of telemedicine in the context of resource-constrained areas and in particular the possibilities to extend its impact from improving individual diagnosis towards strengthening health care systems. A central part of this project was the development of iPath, an Internet- and email-based telemedicine platform, which facilitates medical consultations, knowledge exchange and continuous education on a global scale. A particular emphasis was put on the applicability and accessibility for users from developing countries with limited infrastructure and network connectivity. The complete software was released under an open-source licence in order to allow unrestricted reuse for other institutions. The diagnostic accuracy of this form of telemedicine was studied in two projects from the field of pathology. A retrospective review of over 200 glass slides from each project revealed complete diagnostic concordance between the telemedical diagnosis and review diagnosis in 69% and 85% respectively. Clinically relevant discrepancies were found in 8% and 3.3% of all examinations. Selection of images by the non-expert and communication were found to have the greatest impact on diagnostic accuracy. Both factors can be addressed by training and organisation of workflow. In comparison to submitting material for pathological examination by courier, the turn-around time could be reduced from weeks to days or hours. Besides the more rapid availability of diagnosis, telemedicine enabled a direct dialogue between the surgeon and the pathologist and thus facilitated an implicit permanent medical education. The educational aspects of telemedicine were studied within the scope of a tele-dermatology project in South Africa. Distance collaboration with a dermatologist empowered a general practitioner based in a rural area to diagnose and treat a majority of patients with dermatological problems. Besides the direct benefit of saving the patients the cost of transportation to visit the dermatologist, the general practitioner could strengthen his own diagnostic skills under direct guidance and quality control of a specialist. As a consequence he will be able to treat more patients locally, close to their homes and families. The whole project was implemented within the local health system in order to facilitate a future inclusion of other primary care facilities. Regional telemedicine networks play a major role to ensure relevance and acceptability of consultative and educational telemedicine. Within the scope of the Ukrainian Swiss Perinatal Health Program a telemedicine component was included, and it was found that the use of regional language as well as inclusion of the regional specialists are important for the acceptance of telemedicine and should not be neglected in a era of globalisation. The presented results demonstrate that save and reliable telemedicine can be implemented with limited resources. Telemedicine is suitable in particular to strengthen existing international collaborations and to support professionally isolated medical specialists. Regional collaboration and inclusion of regional specialists are desirable if telemedicine shall help to strengthen health care systems. The application of telemedicine should not only focus on providing care to individual patients, but should explicitly incorporate skills development and capacity building of primary care staff. Organisation of work flow and communication have been found to be the most challenging task for the implementation of telemedicine networks. Resources must be invested not only in technology but more importantly in training and organisation. Utilisation of existing technological infrastructure is advisable wherever possible and greatly reduces the complexity of providing support and maintenance. The presented telemedicine platform provides an efficient tool for the organisation of interdisciplinary, regional and international telemedicine networks. We hope that the unrestricted availability of the software developed during this project will enable other institutions to utilise it for their own purpose and that they will thus be able to allocate resources on the organisation of workflow rather than technology

Telehealth Nursing Research: Adding to the Evidence-base for Healthcare

This paper reviews recent, nurse-led telehealth research with the goal of describing research findings that provide evidence for practice. Methods: Using an iterative search method, of eight electronic databases, 84 nurse-led research papers were separated into intervention research, systematic reviews and meta-analyses, and descriptive research. The main emphasis was on full text analysis of the intervention research. Results: Fifteen intervention research papers reported findings related to cardiovascular disease, diabetes mellitus, older age, young adults, early adolescents, children with special health care needs, people with a stoma, post-partum mothers and nurses. Also reviewed for useable evidence for practice were 10 systematic reviews, two meta-analyses and two papers that described reviews plus meta-analyses. Resuts: Fifty-five papers with descriptive designs are briefly described. Nurse-led intervention research is increasing knowledge about the use of telehealth technology and applications in care delivery. People with healthcare needs do better with individual attention and increased follow-up. People have a tolerance for technology used with them to advance their quality of life and healing but there is a point at which too much technology is overwhelming. Clinical research is a challenge due to the number of extraneous variables that are difficult to control and that can affect a person’s response to the research intervention. Conclusion: Continuation of nurse-led telehealth intervention research will help to ensure that technology used to support and advance care delivery will be evidence-based
