A conceptual framework for integrating the home into patient-centered healthcare processes: Analysis, solution strategies and realization using health enabling technologies

Assistierende Gesundheitstechnologien (AGT) und technische Assistenzsysteme, auch ohne Medizinbezug, können das altersunabhängige Bedürfnis nach komfortablem und sicherem Wohnen in Wohlbefinden gewinnbringend adressieren. Die Einbindung der Wohnung in dieser gesamtheitlichen Perspektive ist nicht beschrieben und die Akteure der entsprechenden Professionen können, aufgrund fehlenden Wissens über sozio-technische Potentiale der Wohnung, im Aufbau von Versorgungsszenarien nicht auf ihre Fähigkeiten zurückgreifen. Ziel der Dissertation ist es, einen Rahmen aus Methoden, Lösungsstrategien und einem exemplarischen Integrationsszenario zur Einbindung der Wohnung in medizinische Versorgungsprozesse zu geben und dabei insbesondere ihre Funktion als neuartigen Gesundheitsstandort zu betrachten. Auf Basis eines sozi-technischen Rollenmetamodells wurden insgesamt elf Rollen herausgearbeitet. Die Wohnung als Messinstrument, Datenspeicher, Informationsquelle, Entscheidungsunterstützungssystem, Diagnostisches Instrument, Therapeut und Aktor, Sozialer Integrator, Präventionsinstrument, Pflegesystem, Gesundheitsmanager und Forschungssystem. Die Rollenhandlungen lassen sich aus den sechs Realisierungsprojekten in die Wirkungsfelder Komfort & Sicherheit, umfassende Pflege und erweiterte medizinische Versorgung mit den Methoden Infrastruktur, Dienstleistung und Netzwerk einteilen, eingefasst von den Prinzipien Öffentlichkeit, Nachhaltigkeit und Wissenschaft. Diese drei Dimensionen bilden das Rahmenkonzept für die "Modellstadtinitiative Braunschweig: Vision Wohnen 2031" als exemplarisches Integrationsszenario und Strategiedokument. Die Instanziierung zeigt, die Wohnung gibt Raum, handelt und verbindet. Sie schafft Beziehungen zwischen ärztlichen, pflegerischen und sozialen Akteuren inter- und multidisziplinärer Versorgungsprozesse mit dem Ziel eines mehrdimensionalen, ganzheitlichen Wohlbefindens. Sie ist transprofessionaler Akteur und Handlungsraum über die medizinische Domäne hinaus zur synergetischen Erfüllung von Zielen anderer Gewerke, wie der Energieoptimierung oder dem Gebäudeschutz.Health-enabling Technologies (HET) and assistive devices, even without medical purpose, can profitably address age-independent well-being in terms of comfortable, safe and healthy living. The integration of homes in this holistic perspective is not described and the actors of the corresponding professions cannot utilize the homes' abilities in the development of care scenarios due to a lack of knowledge about socio-technical potentials of homes. Objective of this dissertation is to provide a framework of methods, strategies and an exemplary integration scenario for integration of the home into healthcare processes and, in particular, to consider its function as a novel healthcare location. Based on a socio-technical role metamodel, a total of eleven roles were identified from six healthcare process models. The home as measuring instrument, data store, information source, decision support system, diagnostic instrument, therapist and actuator, social integrator, prevention system, nursing system, carepath manager and research system. The role actvities can be divided from the six implementation projects into the three application domains comfort & safety, comprehensive care and extended medical care, using the methods infrastructure, service and network, framed by three principles openness, sustainability and science. These three dimensions form the conceptual framework for the "Modellstadtinitiative Braunschweig: Vision Wohnen 2031" as exemplary integration scenario and strategy document. The instantiation shows, that the home gives space, takes action and connects. It creates relationships between medical, nursing and social actors in interdisciplinary and multidisciplinary care processes with the aim of multidimensional, holistic well-being. It is a transprofessional actor and room for action beyond the healthcare domain to synergistically fulfill goals of other domains, such as energy optimization or building protection

Unobtrusive Health Monitoring in Private Spaces: The Smart Home

With the advances in sensor technology, big data, and artificial intelligence, unobtrusive in-home health monitoring has been a research focus for decades. Following up our research on smart vehicles, within the framework of unobtrusive health monitoring in private spaces, this work attempts to provide a guide to current sensor technology for unobtrusive in-home monitoring by a literature review of the state of the art and to answer, in particular, the questions: (1) What types of sensors can be used for unobtrusive in-home health data acquisition? (2) Where should the sensors be placed? (3) What data can be monitored in a smart home? (4) How can the obtained data support the monitoring functions? We conducted a retrospective literature review and summarized the state-of-the-art research on leveraging sensor technology for unobtrusive in-home health monitoring. For structured analysis, we developed a four-category terminology (location, unobtrusive sensor, data, and monitoring functions). We acquired 912 unique articles from four relevant databases (ACM Digital Lib, IEEE Xplore, PubMed, and Scopus) and screened them for relevance, resulting in n=55 papers analyzed in a structured manner using the terminology. The results delivered 25 types of sensors (motion sensor, contact sensor, pressure sensor, electrical current sensor, etc.) that can be deployed within rooms, static facilities, or electric appliances in an ambient way. While behavioral data (e.g., presence (n=38), time spent on activities (n=18)) can be acquired effortlessly, physiological parameters (e.g., heart rate, respiratory rate) are measurable on a limited scale (n=5). Behavioral data contribute to functional monitoring. Emergency monitoring can be built up on behavioral and environmental data. Acquired physiological parameters allow reasonable monitoring of physiological functions to a limited extent. Environmental data and behavioral data also detect safety and security abnormalities. Social interaction monitoring relies mainly on direct monitoring of tools of communication (smartphone; computer). In summary, convincing proof of a clear effect of these monitoring functions on clinical outcome with a large sample size and long-term monitoring is still lacking

Facilitating Inter-Domain Synergies in Ambient Assisted Living Environments

Current Ambient Assisted Living (AAL) environments lack integration of sensors and actuators of other sub-domains. Creating technical and organizational integration is addressed by the BASIS project (Build Automation by a Scalable and Intelligent System), which aims to build a cross-domain home bus system. The main objective of this paper is to present an overview of design, architecture and state of realization of BASIS by describing the requirements development process, underlying hardware design and software architecture. We built a distributed system of one independent building manager with several redundantly meshed segment controllers, each controlling a bus segment with any number of bus nodes. The software system layer is divided into logical partitions representing each sub-domain. Structured data storage is possible with a special FHIR based home centered data warehouse. The system has been implemented in six apartments running under daily living conditions. BASIS integrates a broad range of sub-domains, which poses challenges to all project partners in terms of a common terminology, and project management methods, but enables development of inter-domain synergies like using the same sensor and actuator hardware for a broad range of services and use cases

Health-Enabling Technologies for Telerehabilitation of the Shoulder: A Feasibility and User Acceptance Study

BACKGROUND: After discharge from a rehabilitation center the continuation of therapy is necessary to secure already achieved healing progress and sustain (re-)integration into working life. To this end, home-based exercise programs are frequently prescribed. However, many patients do not perform their exercises as frequently as prescribed or even with incorrect movements. The telerehabilitation system AGT-Reha was developed to support patients with shoulder diseases during their home-based aftercare rehabilitation. OBJECTIVES: The presented pilot study AGT-Reha-P2 evaluates the technical feasibility and user acceptance of the home-based telerehabilitation system AGT-Reha. METHODS: A nonblinded, nonrandomized exploratory feasibility study was conducted over a 2-year period in patients' homes. Twelve patients completed a 3-month telerehabilitation exercise program with AGT-Reha. Primary outcome measures are the satisfying technical functionality and user acceptance assessed by technical parameters, structured interviews, and a four-dimensional questionnaire. Secondary endpoints are the medical rehabilitation success measured by the active range of motion and the shoulder function (pain and disability) assessed by employing the Neutral-0 Method and the standardized questionnaire "Shoulder Pain and Disability Index" (SPADI), respectively. To prepare an efficacy trial, various standardized questionnaires were included in the study to measure ability to work, capacity to work, and subjective prognosis of work capacity. The participants have been assessed at three measurement points: prebaseline (admission to rehabilitation center), baseline (discharge from rehabilitation center), and posttherapy. RESULTS: Six participants used the first version of AGT-Reha, while six other patients used an improved version. Despite minor technical problems, all participants successfully trained on their own with AGT-Reha at home. On average, participants trained at least once per day during their training period. Five of the 12 participants showed clinically relevant improvements of shoulder function (improved SPADI score > 11). The work-related parameters suggested a positive impact. All participants would recommend the system, ten participants would likely reuse it, and seven participants would have wanted to continue their use after 3 months. CONCLUSION: The findings show that home-based training with AGT-Reha is feasible and well accepted. Outcomes of SPADI indicate the effectiveness of aftercare with AGT-Reha. A controlled clinical trial to test this hypothesis will be conducted with a larger number of participants

On Teaching International Courses on Health Information Systems: Lessons Learned during 16 Years of Frank – van Swieten Lectures on Strategic Information Management in Health Information Systems

Background: Health information systems (HIS) are one of the most important areas for biomedical and health informatics. In order to professionally deal with HIS well-educated informaticians are needed. Because of these reasons, in 2001 an international course has been established: The Frank – van Swieten Lectures on Strategic Information Management of Health Information Systems. Objectives: Reporting about the Frank – van Swieten Lectures and about our students‘ feedback on this course during the last 16 years. Summarizing our lessons learned and making recommendations for such international courses on HIS. Methods: The basic concept of the Frank – van Swieten lectures is to teach the theoretical background in local lectures, to organize practical exercises on modelling sub-information systems of the respective local HIS and finally to conduct Joint Three Days as an international meeting were the resulting models are introduced and compared. Results: During the last 16 years, the Universities of Amsterdam, Braunschweig, Heidelberg/Heilbronn, Leipzig as well as UMIT were involved in running this course. Overall, 517 students from these universities participated. Our students‘ feedback was clearly positive. The Joint Three Days of the Frank – van Swieten Lectures, where at the end of the course all students can meet, turned out to be an important component of this course. Based on the last 16 years, we recommend common teaching materials, agreement on equivalent clinical areas for the exercises, support of group building of international student groups, motivation of using a collaboration platform, ensuring quality management of the course, addressing different levels of knowledge of the students, and ensuring sufficient funding for joint activities. Conclusions: Although associated with considerable additional efforts, we can clearly recommend establishing such international courses on HIS, such as the Frank – van Swieten Lectures
