This dissertation consists of three studies that investigate the information privacy & security associated with healthcare technology use. Essay 1 PRISMA-style systematically reviews the existing literature on privacy information disclosure in IoT technology and serves as the theoretical foundation of the current research. It is crucial to comprehend why, how, and under what consequences individuals choose to disclose their personal and health information since doing so is beneficial to the company. This SLR method allows us to find those factors that significantly impact individuals' behavioral intention to disclose personal information while using IoT technologies. Essay 2 posits, develops, and tests a comprehensive theoretical framework built upon the theory of planned behavior and the health belief model to examine factors affecting willingness to disclose PHI in order to use WFDs. A research survey is designed and distributed to a crowdsourcing platform, Mechanical Turk (M-Turk). Research hypotheses are tested using partial least square – structural equation modeling (PLS-SEM). To achieve this purpose, Essay 3 extends the findings from the previous essay and further investigates the caregiver context. Therefore, we developed a novel theoretical model utilizing privacy calculus theory and the technology acceptance model to investigate the willingness of the elderly to disclose personal health information needed to use caregiver robots. Survey data were collected using crowdsourcing utilizing Amazon's Mechanical Turk (M-Turk) and Prolific. Research hypotheses are tested using partial least square – structural equation modelling (PLS-SEM). The findings provide value for academia, practitioners, and policymakers.

New developments such as 'Precision Medicine' and 'Digital Health' are emerging areas in healthcare technology, underpinned by 'convergent technology' or 'cross-industry' innovation. However, convergence results in greater uncertainty and influence from new knowledge and actors, including previously disparate technologies and capabilities, bringing specific challenges in the development of innovations. Although the literature addresses the context of technology convergence, there has been limited research reported on the how such innovation is effected in nascent ecosystems. This qualitative research addresses identified literature gaps, initially by using a combination of ecosystem actor interviews (n=39) to understand the context, followed by five longitudinal in-depth case studies at innovator organisations. Case evidence was obtained from a combination of interviews (n=62), supplemented by field observations, primary documents and evidence from publicly available sources. The data was subjected to multiple coding methods, with plausible causal mechanisms identified through case and cross-case analyses. The research findings identify a set of five interconnected micro-processes (early organisational routines) which together form a non-deterministic activity system that enables an innovator to navigate (the ecosystem), negotiate (a position within it) and nurture (the innovation and ecosystem). The research further identifies the importance of careful balancing between relationally focussed credibility-seeking and advantage-seeking actions as the main driver 'guiding' managers when developing the innovation, the associated business model(s) and value network in the evolving ecosystem. A conceptual model and framework are developed to show the interrelationships between organisational routines, the activity systems and the ecosystem. In developing organisational capabilities, it is argued that convergent innovation requires mostly incremental changes (low depth of change) across many organisational routines (high breadth of change), which reduce the uncertainty of organizational change and thus increase internal acceptance. These findings support the argument that innovators require a more 'systemic' view of innovation and governance approaches contributing to the innovation and capabilities literature. From a practice perspective, the research provides mechanisms for building relational capabilities critical to innovation delivery.

Falls often cause devastating injuries which precipitate hospital and long-term care admission and result in an increased burden on health care services. Fall prevention interventions are used to overcome fall risk factors in an ageing population. There is an increasing need for technology-assisted interventions to reduce health care costs, whilst also lessening the burden that an ageing population increasingly has on health care services. Research efforts have been spent on reducing intrinsic fall risk factors (i.e. functional ability deficits and balance impairments) in the older adult population through the use of technology-assisted interventions, but relatively little effort has been expended on extrinsic risk factors (i.e. unsuitable environmental conditions and lack of assistive equipment use), considering the drive for healthcare outside of the clinical setting into the patients' home. In the field of occupational therapy, the extrinsic fall-risk assessment process (EFAP) is a prominent preventive intervention used to promote independent living and alleviate fall risk factors via the provision of assistive equipment prescribed for use by patients in their home environment. Currently, paper-based forms with measurement guidance presented in the form of 2D diagrams are used in the EFAP. These indicate the precise points and dimensions on a furniture item that must be measured as part of an assessment for equipment. However, this process involves challenges, such as inappropriate equipment prescribed due to inaccurate measurements being taken and recorded from the misinterpretation of the measurement guidance. This is largely due to the poor visual representation of guidance that is provided by existing paper-based forms, resulting in high levels of equipment abandonment by patients. Consequently, there is a need to overcome the challenges mentioned above by augmenting the limitations of the paper-based approach to visualise measurement guidance for equipment. To this end, this thesis proposes the use of 3D visualisation technology in the form of a novel mobile 3D application (Guidetomeasure) to visualise guidance in a well-perceived manner and support stakeholders with equipment prescriptions. To ensure that the artefact is a viable improvement over its 2D predecessor, it was designed, developed and empirically evaluated with patients and clinicians alike through conducting five user-centred design and experimental studies. A mixed-method analysis was undertaken to establish the design, effectiveness, efficiency and usability of the proposed artefact, compared with conventional approaches used for data collection and equipment prescription. The research findings show that both patients and clinicians suggest that 3D visualisation is a promising development of an alternative tool that contains functionality to overcome existing issues faced in the EFAP. Overall, this research makes a conceptual contribution (secondary) to the research domain and a software artefact (primary) that significantly improves practice, resulting in implications and recommendations for the wider healthcare provision (primary).

The constant evolution of medical technology has increased the demand for managing medical devices to ensure safety and effectiveness. In this paper I will investigate how biomedical engineering has addressed the issue of equipment management and identifies strategies to successfully maintain an inventory of medical devices. Through research, on-the-job experience, and in-depth discussions with various biomedical engineering managers, I have been able to document possible equipment strategies and best practices for managing medical devices. There is really no "one size fits all" to medical equipment management due to the various clinical environments, but there are many aspects that remain necessary to ensure proper equipment safety and function while meeting or exceeding various regulatory requirements.

La chirurgie arthroscopique présente actuellement un essor très important pour le bénéfice du plus grand nombre des patients. Cependant, cette technique possède un certain nombre d'inconvénients et il est donc nécessaire pour le médecin de s'entrainer et répéter ses gestes afin de pouvoir exécuter ce type d'opération d'une façon efficace et certaine. En effet, les méthodes traditionnelles d'enseignement de la chirurgie sont basées sur l'autopsie des cadavres et l'entrainement sur des animaux. Avec l'évolution de notre société, ces deux pratiques deviennent de plus en plus critiquées et font l'objet de réglementations très restrictives. Afin d'atteindre un niveau plus élevé, de nouveaux moyens d'apprentissage sont nécessaires pour les chirurgiens. Récemment, la réalité virtuelle commence d'être de plus en plus utilisée dans la médecine et surtout la chirurgie. Les simulateurs chirurgicaux sont devenus une des matières les plus récentes dans la recherche de la réalité virtuelle. Ils sont également devenus une méthode de formation et un outil d'entrainement valable pour les chirurgiens aussi bien que les étudiants en médecine. Dans ce travail, un simulateur de réalité virtuelle pour l'enseignement de la chirurgie arthroscopique, surtout la chirurgie du poignet, a été préesenté. Deux questions principales sont abordées : la reconstruction et l'interaction 3-D. Une séquence d'images CT a été traitée afin de générer un modèle 3-D du poignet. Les deux principales composantes de l'interface du système sont illustrées : l'interaction 3-D pour guider les instruments chirurgicaux et l'interface de l'utilisateur pour le retour d'effort. Dans ce contexte, les algorithmes qui modélisent les objets en utilisant les approches de "Convex Hull" et qui simulent la détection de collision entre les objets virtuels en temps réel, sont présentés. En outre, un dispositif de retour d'effort est utilisé comme une interface haptique avec le système. Cela conduit au développement d'un système à faible coût, avec les mêmes avantages que les appareils professionnels. A cet égard, l'arthroscopie du poignet peut être simulée et les étudiants en médecine peuvent facilement utiliser le système et peuvent apprendre les compétences de base requises en sécurité, flexibilité et moindre coût

Despite defibrillation as the only effective treatment for sudden cardiac arrest (SCA), less than 15% of homes and public facilities have access to an automated external defibrillator (AED). In the United States, ineffective response to SCA cases occurring each year classifies it as a business problem for medical device manufacturing leaders, emergency responders, and bystanders. The purpose of this multicase study was to explore the marketing strategies AED manufacturing leaders use to expand their consumer customer base. Data were collected via in-depth interviews with a purposive sample of participants from 2 U.S. AED manufacturers on the east coast, 2 AED distributors, and 2 healthcare corporations in Texas, as well as a review of company materials. The framework for this study was product life cycle theory. Initial findings for expanding the U.S. AED market indicated that the market was not led by its manufacturers but by its distributors. This finding became an important theme noted from AED manufacturers in considering the consumer segment, an aftermarket from commercial marketing strategies. A common concern for the security of strategic marketing was evident across the AED manufacturer participants with reluctance to discuss business models and marketing plans. A congruent theme was the curtailment of open discussions regarding AED marketing strategies because of security and confidentiality risk. Also, limited number of approved AED manufacturers by the Federal Drug Administration minimizes AED access. Residual outcomes include improving the quality of life for the aging population while reducing the loss of the lives and costs of healthcare. Social implications include preventing sudden cardiac death by providing more accessibility of AEDs to baby boomers.

Diabetes type 1 is an autoimmune, incurable disease which requires careful monitoring and treatment to not result in life threatening complications. Managing the disease is to a great extent made by the patients themselves, implying the disease needs to be constantly taken into consideration when doing even the most simple and regular everyday tasks and activities.This study aims to examine the use of AI in everyday treatment for patients with diabetes type 1. The study investigated what areas AI is already used in diabetes care management, and where there is room for development. The purpose is to give an indication of what role AI has and potentially can have in making the life for patients with diabetes type 1 easier. The research was conducted by a combined literature review and a cross sectional multiple case-study, with semi-structured interviews with people diagnosed with diabetes type 1. The gathered data were analyzed in relation to the triangle of diabetes management and technology acceptance model 2. The first indicates what factors are of highest relevance to not create dangerous situations for a diabetic, and the second relates to whether users would accept the use of a complex technology. The result suggested wide current and further potential use of AI in creating functionality in treatment and everyday management of the disease. Further, it became evident that technological tools simplify the lives of diabetics but there are several areas where AI could be further implemented in order to improve it even further.

The minimally invasive approach of arthroscopy means less pain and faster recovery time for patients compared to open surgery. However, it implies a high difficulty of performance. Therefore, surgeon should remain at a high level of technical and professional expertise to perform such operations. Surgeon’s skills are being developed over years of surgical training on animals, cadavers and patients. Nowadays, cadavers and animal specimens present an ethical problem also the practice on real humans is usually risky. For surgeons to reach a high level, new and alternative ways of performing surgical training are required. Virtual reality technology has opened new realms in the practice of medicine. Today, virtual reality simulators have become one of the most important training methods in the medical field. These simulators allow medical students to examine and study organs or any structure of the human body in ways that were not possible few years earlier. Similarly, the surgeon as well as the medical student can gain a valuable experience by performing a particular surgery with an anatomical accuracy and realism as it is actually performed in the real world. Thus, they can practice on virtual operation before they proceed and operate on real patients. In this thesis, a virtual reality training simulator for wrist arthroscopy is introduced. Two main issues are addressed: the 3-D reconstruction process and the 3-D interaction. Based on a sequence of CT images a realistic representation of the wrist joint is obtained suitable for the computer simulation. Two main components of the computer-based system interface are illustrated: the 3-D interaction to guide the surgical instruments and the user interface for haptic feedback. In this context, algorithms that model objects using the convex hull approaches and simulate real time exact collision detection between virtual objects are presented. A force feedback device, coupled with a haptic algorithm, is used as a haptic interface with the computer simulation system. This leads in the development of a low cost system with the same benefits as professional devices. In this regard, the wrist arthroscopy can be simulated and medical students can learn the basic skills required with safety, flexibility and less cost / La chirurgie arthroscopique présente actuellement un essor très important pour le bénéfice du plus grand nombre des patients.
