RESUMO

This article illustrates the maturation process of innovative technologies in the healthcare domain. The role and the involvement of the stakeholders are explained, as well their interaction in the ecosystem. We focus on how the synergy between partners improves efficiency, boosts product development and accelerates market access. The spiral of the innovation concept is introduced to illustrate the different stages ensuring the correct development of a medical technology. This iterative cycle drives the product maturation, according to medical needs and feedback, and ensures the correct implementation of the innovation in the clinical framework. We finally illustrate how the innovation process is applied to successful drive the ongoing SERENE-IoT project: the spiral of innovation concept is specifically adapted to fit with the project requirements with the final ibjective to identify a panel of medico-economic indicators and to establish the medical service delivered and the opportunities in order to capture the full benefit of the proposed technology.

RESUMO

Information value chain theory provides a straightforward approach to information system evaluation and design. It first separates the different benefits and costs that might be associated with the use of a given information technology at different stages along a value chain stretching from user interaction to real world outcome. Next, using classical decision theoretic measures such as probabilities and utilities, the resulting value chain can be used to create a profile for a particular technology or technology bundle. Value chain analysis helps focus on the reasons for system implementation success or failure. It also assists in making comparative assessments amongst different solutions, to understand which might be best suited for different clinical contexts.

RESUMO

Both the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT) aim at understanding better why users accept or reject a given technology, and how user acceptance can be improved through technology design. Two case studies are presented where TAM and UTAUT were successfully used in a health care setting to predict technology adoption. Both models have found popularity in health care. However, recent reviews show that TAM and UTAUT failed to provide stable predictive capabilities for acceptance and use of technologies in health care. Reasons for this may be the specific context of health care, where not only the technology, but also socio-organizational and cultural factors influence technology acceptance.

RESUMO

Distributed cognition theory posits that our cognitive tasks are so tightly coupled to the environment that cognition extends into the environment, beyond the skin and the skull. It uses cognitive concepts to describe information processing across external representations, social networks and across different periods of time. Distributed cognition lends itself to exploring how people interact with technology in the workplace, issues to do with communication and coordination, how people's thinking extends into the environment and sociotechnical system architecture and performance more broadly. We provide an overview of early work that established distributed cognition theory, describe more recent work that facilitates its application, and outline how this theory has been used in health informatics. We present two use cases to show how distributed cognition can be used at the formative and summative stages of a project life cycle. In both cases, key determinants that influence performance of the sociotechnical system and/or the technology are identified. We argue that distributed cognition theory can have descriptive, rhetorical, inferential and application power. For evidence-based health informatics it can lead to design changes and hypotheses that can be tested.

RESUMO

Technologies are often viewed as the route to better, safer and more efficient care, but technology projects rarely deliver all the benefits expected of them. Based on a literature review and empirical case studies, we developed a framework (NASSS) for studying the non-adoption, abandonment and challenges to scale-up, spread and sustainability of technology-supported change efforts in health and social care. Such projects meet problems usually because they are too complex - and because the complexity is sub-optimally handled. NASSS consists of six domains - the illness or condition, the technology, the value proposition, the individuals intended to adopt the technology, the organisation(s) and the wider system - along with a seventh domain that considers how all these evolve over time. The NASSS framework incorporates a number of other theories and analytic approaches described elsewhere in this book. It is not intended to offer a predictive or formulaic solution to technology adoption. Rather, NASSS should be used to generate a rich and situated narrative of the multiple influences on a complex project; to identify parts of the project where complexity might be reduced; and to consider how individuals and organisations might be supported to handle the remaining complexities better.

RESUMO

Solar cell industry produces high quantities of waste in form of broken, damaged, and rejected cells, whereas milling and filtering practices are typically used to recover the valuable materials (Al, Ag and Si) from such Waste Solar Cell Wafers (WSCWs). This recycling approach has its disadvantages, e.g. excessive energy consumption and dust emission causing loss of valuable metals. To fulfil the concept of Zero Waste for WSCWs, the authors present a sustainable technology for liberation of valuable metals from WSCWs and synthesis of added value products, in particular Ag nanoparticles and Al microparticles. The suggested technology consisted of three different approaches combined to liberate each material individually. The technology started with an Al layer disintegration process using Dimethyl Sulfoxide (as an eco-friendly and sustainable solvent) supported by ultrasonic treatment to break van der Waals' bonding between spherical Al microparticles that compose the Al paste layer, thus liberating Al in microparticle suspension form with particle size ∼3 µm, recovery rate >98%. After that, leaching by nitric acid and other eco-friendly reagents (Sodium Chloride, Ammonia solution and glucose syrup) assisted by ultrasonic treatment was used to dissolve Ag and later precipitate it in form of nanoparticles with avg. size 30 nm, yield >92%. Finally, etching using paste containing phosphoric acid was done to remove anti-reflection coating and purify the Si substrate with final recovery rate >99%. SEM-EDS, XRD, FTIR, and TEM were used for analysis of extracted materials as well as changes in the solvent. Investigation was also concerned with determining economic/global warming impacts of the technology.

RESUMO

In this paper we elaborate a preliminary framework to fill this gap and describe the potential contributions of HFE to improve digital health interventions, at the macro, meso and micro level of a health system. Researchers present a practical approach, integrated with some limited reflections on methodological aspects, recently covered in a position paper [8], while previously in conference series and handbooks. This paper presents a HFES perspective on digital health - from the macro, meso and micro level to improve patient safety and delivery of quality care. Experts in HFE can play a key role in creating evidence for an ethical and effective design of digital health intervention and providing support to their implementation and evaluation at the macro, meso and micro level. This framework may help to integrate HFE at the different levels of the system and following the tracks of organization, technology and human factors.

RESUMO

This paper presents preliminary results from a larger project led with the French company Auxivia. The latter offers a smart drinking glass (SDG), supporting monitoring daily water intakes of elderly people and helping identify residents to encourage. Contexts and work organizations can deeply differ from a nursing home to another and can impact the use of the SDG. Based on a comparison between two nursing homes, we unveil the impact of both work organizations on the integration of technology requirements. We discuss the results by providing recommendations to improve the integration of SDGs in various work organizations.

RESUMO

Security, privacy, transparency, consent, and data sharing are major challenges that healthcare institutions must address today. The explosion of the Internet of Things (IoT), the enactment of the General Data Protection Regulation (GDPR), the growing trend of patients self-managing their diseases, and the eagerness of patients to share their self-collected health data with primary and secondary health organisations further increase the complexity of these challenges. Smart contracts, based on blockchain technology, can be a legitimate approach for addressing these challenges. Smart contracts define rules and penalties in an agreement, enforce those rules, and render them irrevocable. This paper presents a state-of-the-art review (as of May 2018) of the possible usages of smart contracts in healthcare and focuses on data sharing between patients, doctors, and institutions.

RESUMO

Experiences and outcomes of critically ill patients reflect quality of intensive care. The aim of this study was twofold: a) to investigate factors affecting patients' experiences to Intensive Care Units (ICUs) and b) to measure patients' post discharge Health-Related Quality of Life (HRQOL). METHODS: A cross-sectional study with retrospective data collection was carried out. The participants (n=108) were discharged patients from four ICUs of three military hospitals in Athens. Telephone interviews were conducted using the "Patient Empowerment Questionnaire" and "Quality of life Questionnaire". RESULTS: Patients suffering from pain (p<0.001), polytraumatized or patients underwent a "non-scheduled surgery" (p=0.001) reported worse sleep at night. Mechanical ventilation was associated positively with pain relief (p=0.021). Extended length of stay (p<0.001), bad health status prior ICU admission (p=0.005), "polytrauma" and "non-scheduled surgery" patients (p=0.032), mechanical ventilation (p=0.005) and pain during ICU stay (p=0.04) were correlated with worse HRQOL after discharge. CONCLUSIONS: ICU staff must consider the factors that affected patients' experiences during their ICU stay and worsened HRQOL after discharge. Adoption of new technological innovations could help them to improve the quality of intensive care provided.

RESUMO

One of the major problems that a national health system face is the lack of a unified clinical data management. In Greece, the critical and sensitive medical data generated during a patient lifetime are fragmented in one or more hospitals and healthcare services are not characterized by a 'continuity' factor. There is not the appropriate technological and administrative infrastructure for a unified patient medical history, prescriptions, laboratory tests or therapeutic plan. Technological, administrative and economic factors have led to this situation. We propose the integration and implementation of a blockchain network as a complementary technology to the existing information systems, so reliable and effective information management could be provided by a healthcare organization or the national healthcare system. Blockchain technology could be implemented as a bridge that can provide information systems interoperability within a hospital or between different hospitals.

RESUMO

The blockchain is one of the most popular information technologies and, at the same time, it was discredited by stories about crashes of multiple cryptocurrency projects. Even though this technology has recently found application in many areas not related to cryptocurrencies, mainly for security purposes, the attitude towards it remains wary. Herein we shall try to demonstrate that blockchain is something going far beyond cryptocurrency and security issues, and may become one of the fundamental information technologies in future healthcare.

RESUMO

New and alternative sanitation systems are increasingly discussed and find their way into implementation. However, discussions on sanitation concepts often are held in a rather emotional way. Furthermore, not all the available sanitation concepts might be known to the decision maker. The work presented here attempts to contribute to a good discussion and decision making process by compiling available technologies, by defining easy-to-implement criteria for a sustainability assessment method and by integrating these results into a simulation tool which allows to visualize the related resource fluxes (e.g. those on nutrients, such as N, P and K) and to analyse different sanitation options with regard to their capital and operational costs and with regard to environmental impact criteria such as greenhouse gas emissions. Whilst the calculations are to be considered as being approximate in their nature (due to uncertainties or lack of suitable input data), this tool allows the planners, with sometimes little modelling experience, to consider the characteristics of sanitation systems. Whilst starting from earlier work, such as Eawag's Sanitation Compendium and work on material flow analysis, work described in this contribution merges resource flux modelling, easy-to-use simulation and visualization and methods of life cycle assessment and life cycle costing. The simulation tool is freely available on https://www.ifak.eu/en/products/sampsons.

RESUMO

The immersive technologies of Virtual and Augmented Reality offer a new medium for visualisation. Where previous technologies allowed us only two-dimensional representations, constrained by a surface or a screen, these new immersive technologies will soon allow us to experience three dimensional environments that can occupy our entire field of view. This is a technological breakthrough for any field that requires visualisation, and in this chapter I explore the implications for medical visualisation in the near-to-medium future.First, I introduce Virtual Reality and Augmented Reality respectively, and identify the essential characteristics, and current state-of-the-art, for each. I will then survey some prominent applications already in-use within the medical field, and suggest potential use cases that remain under-explored. Finally, I will offer practical advice for those seeking to exploit these new tools.

RESUMO

Dementia is on the rise as our population ages and it is still untreatable. Our global society is changing but so is our technological landscape. Virtual Reality has been around for a while but it has not been widely adopted within the general healthcare sector, never mind for niche use cases, that is until now….

RESUMO

3D digital technologies have advanced rapidly over recent decades and they can now afford new ways of interacting with anatomical and cultural artefacts. Such technologies allow for interactive investigation of visible or non-observable surfaces, haptic generation of content and tactile experiences with digital and physical representations. These interactions and technical advances often facilitate the generation of new knowledge through interdisciplinary and sympathetic approaches.Scientific and public understanding of anatomy are often enhanced by clinical imaging technologies, 3D surface scanning techniques, 3D haptic modelling methods and 3D fabrication systems. These digital and haptic technologies are seen as non-invasive and allow scientists, artists and the public to become active investigators in the visualisation of, and interaction with, human anatomy, remains and histories.Face Lab is a Liverpool John Moores University research group that focuses on creative digital face research; specifically the further development of a 3D computerized craniofacial depiction system, utilizing 3D digital technologies in facial analysis and identification of human remains for forensic investigation, or historical figures for archaeological interpretation.This chapter explores the affordances of such interactions for the non-destructive production of craniofacial depiction, through a case-study based exploration of Face Lab workflow.

RESUMO

OBJECTIVE: To calculate the cost and assess the results on implementing technological resources that can prevent medication errors. METHODS: A retrospective, descriptive-exploratory, quantitative study (2007-2015), in the model of case study at a hospital in the Brazilian Southeastern Region. The direct cost of each technology was calculated in the drug chain. Technological efficacy was observed from the reported series of the indicator incidence of medication errors. RESULTS: Thirteen technologies were identified to prevent medication errors. The average cost of these technologies per year in the prescription stage was R$ 3.251.757,00; in dispensing, R$ 2.979.397,10; and in administration, R$ 4.028.351,00. The indicator of medication error incidence decreased by 97.5%, gradually between 2007 to 2015, ranging from 2.4% to 0.06%. CONCLUSION: The average cost per year of the organization to implement preventive technologies in the drug chain totaled up R$ 10.259.505,10. There was an average investment/year of R$ 55,72 per patient and its association with smaller indicator of incidence of medication errors confirms a satisfactory result in this reported series regarding such investment.
