[ES] La constante evolución de la tecnología y la búsqueda de nuevas aplicaciones que mejoren la vida de las personas ha llevado a la incorporación de estas tecnologías en el organismo. Las redes inalámbricas de área corporal (WBAN) son un buen ejemplo de esto, que consisten en redes de comunicaciones ubicadas en el propio cuerpo, tanto en la superficie como implantadas en su interior mediante el uso de dispositivos inalámbricos. Estas redes utilizan el cuerpo humano como medio de transmisión, por lo que debe evaluarse la influencia del mismo sobre la propagación. Además, las nuevas generaciones de comunicaciones móviles se están moviendo hacia el uso de frecuencias cada vez más altas, como las ondas milimétricas, que son más sensibles a la presencia de cualquier objeto en el entorno, incluidos los humanos. La investigación y el diseño de antenas y dispositivos que tengan en cuenta el cuerpo humano requiere pruebas en el entorno donde se supone que deben usarse. Los fantomas se convierten en una herramienta para evaluar la transmisión de señales electromagnéticas en un medio equivalente al cuerpo para evitar la experimentación en humanos o animales. Además de eso, se puede estudiar la influencia de estas ondas electromagnéticas sobre los propios tejidos en cuanto a la tasa de absorción específica (SAR). / [CA] L'evolució constant de la tecnologia i la recerca de noves aplicacions que milloren la vida de les persones ha portat a la incorporació d'aquestes tecnologies en l'organisme. Les xarxes sense fils d'àrea corporal (WBAN) són un bon exemple d'açò, que consisteixen en xarxes de comunicacions ubicades al propi cos, tant en la superfície com implantades en el seu interior mitjançant l'ús de dispositius sense fils. Aquestes xarxes empren el cos humà com a medi de transmissió, per la qual cosa se n'ha d'avaluar la influència sobre la propagació. A més, les noves generacions de comunicacions mòbils s'estan movent cap a l'ús de freqüències cada vegada més altes, com les ones mil·limètriques, que són més sensibles a la presència de qualsevol objecte en l'entorn, incloent-hi els humans. La investigació i el disseny d'antenes i dispositius que tinguen en compte el cos humà requereix proves en l'entorn on se suposa que han d'usar-se. Els fantomes esdevenen una eina per a avaluar la transmissió de senyals electromagnètics en un medi equivalent al cos per tal d'evitar l'experimentació en humans o animals. A més d'això, es pot estudiar la influència d'aquestes ones electromagnètiques sobre els teixits mateixos en relació amb la taxa d'absorció específica (SAR). / [EN] The constant evolution of technology and the search for new applications that improve people's lives has led to the arrival of the incorporation of these technologies in the organism. Wireless body area networks (WBANs) are a good example of this, consisting of communications networks located in the body itself, both on the surface and implanted inside it through the use of wireless devices. These networks use the human body as the transmitting medium, so its influence over the propagation has to be assessed. Besides, new generations of mobile communications are moving towards the use of higher frequencies, as the millimetre waves, which are more sensitive to the presence of any object in the environment, including humans. The research and design of antennas and devices that take into account the human body requires testing in the environment where these are supposed to be used. Phantoms become a tool for evaluating the transmission of electromagnetic signals in a body-equivalent medium in order to avoid experimentation on humans or animals. In addition to that, the influence of these electromagnetic waves over the tissues themselves can be studied with regard to the specific absorption rate (SAR). / This thesis has been possible thanks to the funding contribution of the Universitat Polit`ecnica de Val`encia through the PAID-01-16 programme.

Recent years have seen an influx of medical technologies capable of remotely monitoring the health and behaviours of individuals to detect, manage and prevent health problems. Known collectively as personal health monitoring (PHM), these systems are intended to supplement medical care with health monitoring outside traditional care environments such as hospitals, ranging in complexity from mobile devices to complex networks of sensors measuring physiological parameters and behaviours. This research project assesses the potential ethical implications of PHM as an emerging medical technology, amenable to anticipatory action intended to prevent or mitigate problematic ethical issues in the future. PHM fundamentally changes how medical care can be delivered: patients can be monitored and consulted at a distance, eliminating opportunities for face-to-face actions and potentially undermining the importance of social, emotional and psychological aspects of medical care. The norms evident in this movement may clash with existing standards of 'good' medical practice from the perspective of patients, clinicians and institutions. By relating utilitarianism, virtue ethics and theories of surveillance to Habermas' concept of colonisation of the lifeworld, a conceptual framework is created which can explain how PHM may be allowed to change medicine as a practice in an ethically problematic way. The framework relates the inhibition of virtuous behaviour among practitioners of medicine, understood as a moral practice, to the movement in medicine towards remote monitoring. To assess the explanatory power of the conceptual framework and expand its borders, a qualitative interview empirical study with potential users of PHM in England is carried out. Recognising that the inherent uncertainty of the future undermines the validity of empirical research, a novel epistemological framework based in Habermas' discourse ethics is created to justify the empirical study. By developing Habermas' concept of translation into a procedure for assessing the credibility of uncertain normative claims about the future, a novel methodology for empirical ethical assessment of emerging technologies is created and tested. Various methods of analysis are employed, including review of academic discourses, empirical and theoretical analyses of the moral potential of PHM. Recommendations are made concerning ethical issues in the deployment and design of PHM systems, analysis and application of PHM data, and the shortcomings of existing research and protection mechanisms in responding to potential ethical implications of the technology.

A challenge for the clinical management of Parkinson's disease (PD) is the large within- and between-patient variability in symptom profiles as well as the emergence of motor complications which represent a significant source of disability in patients. This thesis deals with the development and evaluation of methods and systems for supporting the management of PD by using repeated measures, consisting of subjective assessments of symptoms and objective assessments of motor function through fine motor tests (spirography and tapping), collected by means of a telemetry touch screen device. One aim of the thesis was to develop methods for objective quantification and analysis of the severity of motor impairments being represented in spiral drawings and tapping results. This was accomplished by first quantifying the digitized movement data with time series analysis and then using them in data-driven modelling for automating the process of assessment of symptom severity. The objective measures were then analysed with respect to subjective assessments of motor conditions. Another aim was to develop a method for providing comparable information content as clinical rating scales by combining subjective and objective measures into composite scores, using time series analysis and data driven methods. The scores represent six symptom dimensions and an overall test score for reflecting the global health condition of the patient. In addition, the thesis presents the development of a web-based system for providing a visual representation of symptoms over time allowing clinicians to remotely monitor the symptom profiles of their patients. The quality of the methods was assessed by reporting different metrics of validity, reliability and sensitivity to treatment interventions and natural PD progression over time. Results from two studies demonstrated that the methods developed for the fine motor tests had good metrics indicating that they are appropriate to quantitatively and objectively assess the severity of motor impairments of PD patients. The fine motor tests captured different symptoms; spiral drawing impairment and tapping accuracy related to dyskinesias (involuntary movements) whereas tapping speed related to bradykinesia (slowness of movements). A longitudinal data analysis indicated that the six symptom dimensions and the overall test score contained important elements of information of the clinical scales and can be used to measure effects of PD treatment interventions and disease progression. A usability evaluation of the web-based system showed that the information presented in the system was comparable to qualitative clinical observations and the system was recognized as a tool that will assist in the management of patients.

L’accessibilité à des soins de santé pour une population habitant une région éloignée au Québec représente un défi de taille pour le Ministère de la santé et des services sociaux. Des solutions, telles que la télésanté, ont été présentées afin de pallier ce problème. Le RUIS McGill a ainsi développé un programme de téléobstétrique afin de desservir une population de femmes inuites à grossesse à risque élevé (GARE) habitant le Nunavik. L’objectif de ce mémoire fut de comprendre l’impact du service de téléobstétrique du RUIS McGill sur la santé des femmes et de leur nouveau-né ainsi que sur les coûts de santé et l’utilisation des services suite à son implantation au Centre de santé et de services sociaux Inuulitsivik sur la côte de la baie d’Hudson. Les femmes inuites à grossesse à risque élevé et leurs enfants de la région de la baie d’Hudson du Nunavik, éloignés des services obstétriques spécialisés, sont visés. Le service de téléobstétrique permet un accès aux obstétriciens du RUIS McGill localisés à Montréal. Un devis quasi-expérimental est utilisé pour examiner trois hypothèses portant sur l’état de santé des mères et des enfants, sur l’utilisation des services de santé et sur leurs coûts. Le service de téléobstétrique est devenu fonctionnel en 2006, offrant la possibilité de constituer une étude avant-après à deux groupes de femmes, soit celles ayant accouché avant 2006 (prétest) et celle ayant accouché après 2012 (post-test). La collecte de donnée se fit, dans son intégralité, par l’entremise des dossiers médicaux papier des participantes permettant l’analyse de 47 dossiers pour le prétest et de 81 dossiers pour le post-test. L’exécution d’analyse de covariance, de régression logistique et du test non paramétrique de Mann-Witney permit de conclure que le prétest et le post-test ne différent que sur deux variables, soient le poids à la naissance, plus faible dans le post-test et la pression artérielle de la mère à la naissance, plus élevée dans le post-test. Pour l’ensemble des autres variables portant sur les trois hypothèses à l’étude, les résultats de ce mémoire ne démontrent aucune différence significative entre les deux groupes démontrant ainsi qu’une même qualité de soins a été conservée suite à l’implantation du programme de téléobstétrique. Sur la base des résultats, ce mémoire recommande de revoir et modifier les objectifs du programme; de partager les bornes de communication de télésanté avec d’autres spécialités; d’entreprendre une évaluation du programme axée sur les coûts; de suivre rigoureusement l’utilisation du programme pour en maximiser l’efficacité et le potentiel; d’établir un tableau de bord; et d’entreprendre une étude évaluative comparative dans un service de téléobstétrique comparable. / Health care accessibility to the population located in a remote region of Quebec represents a challenge for the Ministère de la santé et des services sociaux. Solution such as telemedicine has been used to mitigate this issue. Therefore RUIS McGill has developed a teleobstetric program helping Inuit women in Nunavik with their risky pregnancy. This thesis’s objective is to understand the impact of the RUIS McGill teleobstetric program on the mother and her new born health plus the cost and utilization of health services following its implementation in the Inuulitsivik Health & and Social Services Centre located on Hudson Bay Shore. Inuit women at high risk pregnancy and their children in the region of Nunavik's Hudson Bay, who are far away from specialist in obstetric, are targeted. The teleobstetric program provides access to the RUIS McGill obstetricians located in Montreal. A quasi- experimental design was used to examine three hypotheses about the mothers and their children health, the use of health services and their costs. The teleobstetric program became operational in 2006, providing the ability to be a before-after study with two groups of women, those who delivered before 2012 (pre-test) and those who delivered after 2006 (post-test). The data collection took place, in its entirety, through paper medical records of the participants allowing the analysis of 47 cases for the pre-test and 81 cases for the post-test. Variance and covariance’s analysis, logistical regression and the non-parametric Mann-Witney test has allowed to conclude that the pre-test and post-test are different for only two variables which is the weight at birth, lower in the post-test and for the blood pressure of the mother at birth, higher in the post-test. For all other variables based on the three hypothesis of this thesis, results show no significate difference between pre-test and post-test, illustrating that the same level of quality has been conserved after the implementation of the teleobstetric program. Based on results, this thesis recommends reviewing and modifying the program’s objectives; sharing telehealth communication terminals with other specialties; undertaking an assessment of the cost-based program; strictly monitor the use of the program to maximize efficiency and potential; establishing a dashboard; and undertaking a comparative evaluation study in a comparable teleobstetric service.

Telemedizin ist der Einsatz von Telekommunikation und Informatik, um medizinische Dienstleistungen zu erbringen oder zu unterstützen, wenn die Teilnehmer räumlich getrennt sind. Die einzelnen telemedizinischen Anwendungen sind im Vordringen begriffen. Telemedizin ist allerdings kein eigenes Fachgebiet, sondern eine Methode, herkömmliche medizinische Maßnahmen zu unterstützen und zu verbessern. Da die Teilnehmer telemedizinischer Anwendungen nicht am selben Ort und zur selben Zeit agieren müssen, ist Telemedizin prädestiniert für die Überwindung der Sektorierung des Gesundheitssystems. Telemedizin kann insbesondere Rationalisierungsreserven mobilisieren und medizinische Dienstleistungen effektiver und effizienter gestalten. Ungeachtet dessen gibt es fünf Problemfelder, die beobachtet und weiter entwickelt werden müssen, um Telemedizin auch für die Zukunft möglich zu machen: Die unterschiedlichen Kommunikationsstandards müssen harmonisiert werden, damit der Datenfluß zwischen den Teilnehmer optimiert werden kann. Krankenkassen und Leistungserbringer müssen gemeinsam eine solide Basis für die Finanzierung derjenigen telemedizinischen Dienstleistungen etablieren, die dem Stand der wissenschaftlichen Erkenntnis entsprechen. Telemedizin mit Auslandsbeteiligung zieht in der Regel haftungsrechtliche Kollisionen nach sich, die von den Teilnehmern durch eine Rechtswahl- und eine Gerichsstandsvereinbarung vermieden werden können. Die sozialrechtlichen Möglichkeiten, insbesondere solche, Praxisnetze zu bilden, müssen noch in Einklang mit den berufsrechtlichen Vorgaben gebracht werden, da diese einer überörtlichen Leistungserbringergemeinschaft und einer entsprechenden Information des Patienten zum Teil noch im Weg stehen.Die durch die Telemedizin neu entstehenden Möglichkeiten der Kommunikation müssen durch zusätzliche Maßnahmen für Datenschutz und Datensicherheit flankiert werden. Insbesondere bei Datenübertragungen ins Ausland sollten sich die Teilnehmer durch eine gesonderte Einwilligung des Patienten in diesen Datenfluß absichern. / Telemedicine is the use of information and telecommunication technologies to provide and support health care when distance separates the participants. The single uses of telemedicine are growing in quality and quantity. Telemedicine, however, is not a medical field of its own, but a tool that can be used in most fields of medicine to enhance and support communication procedures. Since the participants must not act at the same time and at the same venue, telemedicine is bound to overcome the sectoral boundaries in a health system, which is separated in an outpatient and an inpatient world. Telemedicine can help to mobilise the health systems rationalisation potential and make procedures more effective and more efficient. There still are five tasks that have to be observed and to be solved, to make telemedicine possible in the future: Harmonisation of communicational standards must progress to optimise communication between the participants. Health insurance funds and medical persons must cooperate to insure a solid basis of financing for telemedicinal procedures that are state of the art. Participants of cross-border telemedicine must be aware of colliding laws and are well advised to agree upon the law to be applied and the court in charge. The professional law for doctors in Germany must be reconciled with the managed care concepts of practice networks that are legally permissible in terms of social law. Data protection and data security must be ensured under the new conditions of telemedicine. Especially cross-border data flow should be based on the informed consent of the patient involved

This thesis employs data-mining techniques and modern information and communication technology to develop methods which may improve efficiency of prevention oriented telemedical programs. In particular this thesis uses the ITAREPS program as a case study and demonstrates that an extension of the program based on the proposed methods may significantly improve the program's efficiency. ITAREPS itself is a state of the art telemedical program operating since 2006. It has been deployed in 8 different countries around the world, and solely in the Czech republic it helped prevent schizophrenic relapse in over 400 participating patients. Outcomes of this thesis are widely applicable not just to schizophrenic patients but also to other psychotic or non-psychotic diseases which follow a relapsing path and satisfy certain preconditions defined in this thesis. Two main areas of improvement are proposed. First, this thesis studies various temporal data-mining methods to improve relapse prediction efficiency based on diagnostic data history. Second, latest telecommunication technologies are used in order to improve quality of the gathered diagnostic data directly at the source.

La gestion électronique des données médicales consiste autant dans le simple traitement automatisé des données personnelles que dans le partage et l'échange de données relatives à la santé. Son encadrement juridique est assuré, à la fois, par les règles communes au traitement automatisé de toutes les données personnelles et par celles spécifiques au traitement des données médicales. Cette gestion, même si elle constitue une source d'économie, engendre des problèmes de protection de la vie privée auxquels le gouvernement français tente de faire face en créant l'un des meilleurs cadres juridiques au monde, en la matière. Mais, de grands chantiers comme celui du dossier médical personnel attendent toujours d'être réalisés et le droit de la santé se voit devancer et entraîner par les progrès technologiques. Le développement de la télésanté bouleverse les relations au sein du colloque singulier entre le soignant et le soigné. L'extension des droits des patients, le partage de responsabilité, l'augmentation du nombre d'intervenants, le secret médical partagé constituent de nouveaux enjeux avec lesquels il faut, désormais compter. Une autre question cruciale est celle posée par le manque d'harmonisation des législations augmentant les risques en cas de partage transfrontalier de données médicales / The electronic management of medical data is as much in the simple automated processing of personal data in the sharing and exchange of health data . Its legal framework is provided both by the common rules to the automated processing of all personal data and those specific to the processing of medical data . This management , even if it is a source of economy, creates protection issues of privacy which the French government tries to cope by creating one of the best legal framework in the world in this field. However , major projects such as the personal health record still waiting to be made and the right to health is seen ahead and lead by technological advances . The development of e-health disrupts relationships within one dialogue between the caregiver and the patient . The extension of the rights of patients , sharing responsibility , increasing the number of players , the shared medical confidentiality pose new challenges with which we must now count. Another crucial question is posed by the lack of harmonization of legislation increasing the risks in cross-border sharing of medical

Syftet med uppsatsen är att kartlägga behovet av en testbädd för telemedicinska produkter och att analysera krav som medicintekniska företag ställer på en testbäddsmiljö för samverkan med sjukvården. Målet har varit att konkretisera resultatet i en kommersialiseringsplan för Karolinska Testbädd för Telemedicin och eHälsa, vid Medicinsk Teknik på Karolinska Universitetssjukhuset. Vid genomförandet av undersökningen har totalt 19 intervjuer och ytterligare 6 telefonintervjuer genomförts med dels representanter från medicintekniska företag och sjukvården och dels med samarbetsstrukturer för medicinsk teknik och möjliga finansiärer. En enkätundersökning har genomförts för att kvantifiera resultatet från intervjuerna. Webbutskick har gjorts till 279 företag med verksamhet inom områdena medicinsk teknik, IT och telekom. Uppsatsen beskriver hur den kliniska forskningen inom området medicinsk teknik har förändrats de senaste decennierna och hur situationen ser ut idag. Utmaningar som den svenska hälso- och sjukvården står inför presenteras, som demografiska förändringar, ökade sjukvårdskostnader, dyrare behandlingsmetoder och färre kommersialiserade innovationer inom medicinsk teknik.  Omständigheter som påverkar produktutveckling för hälso- och sjukvården belyses, dels genom den regulatoriska gränsdragningen mellan IT-produkter och medicintekniska produkter och dels utifrån en genomgång av forskning inom produkt- och tjänsteutveckling och utifrån de frågor kring hur företag bedriver produktutveckling som ställts i intervjuerna och i webbenkäten. Resultatet visar att företagen i högsta grad är beroende av samarbete med sjukvården i olika faser av sin produktutvecklingsprocess och att flera företag uttrycker ett behov av en testbäddsstruktur. Företagen samarbetar med vården framförallt för att det möjliggör att utveckla mer vårdanpassade produkter. Samarbete med vården ger kortare utvecklingstider och därmed minskade utvecklingskostnader. Det förenklar även arbetet med validering av produkters funktionalitet. Flera företag har utarbetade samarbeten direkt in på vårdavdelningar, medan andra i dagsläget saknar nödvändiga samarbetsstrukturer. Studien har identifierat ett flertal företag som visat intresse för ett samarbete med Testbädden och ytterligare ett antal som har önskat att få mer information om vad Testbädden kan erbjuda. I kommersialiseringsplanen föreslås Karolinska Testbädd för Telemedicin och eHälsa fokusera på sin nisch samt vidareutveckla den kompetens som företagen saknar. Testbädden bör arbeta vidare med att utveckla både externa kontakter och den interna samverkansorganisationen på Karolinska för att möjliggöra effektiva, smidiga och kvalitativa samarbeten mellan företag och sjukhusets avdelningar. / The purpose is to study the demand for a testbed for telemedicine and to analyze the medical device-developing companies’ requirements on the testbed’s facilities when collaborating with the healthcare sector in their product development. The study’s aim is to result in a commercialization plan for Karolinska Testbed for telemedicine and eHealth, at the department of Biomedical Engineering at Karolinska University Hospital. During the study, 19 interviews and 6 telephone-interviews has been held with people from the medical device industry, hospitals, potential funders and collaboration structures which foster medical device development. A web-survey has been sent to 279 companies within the fields of medical technologies, IT and telecom, to quantify the results from the interviews. The study describes how the clinical research on medical technologies has changed over the last decades and what the situation is like today. Present and forthcoming challenges to the Swedish health care system is presented, like demographic changes, increasing healthcare-costs, expensive treatments and the scarcity of medical device innovations being commercialized. Obstacles affecting the medical device development are studied, including the regulatory differences between IT and medical devices. An analysis of the research on product and service development is also looked at from the perspectives on how the medical device companies develop their products, which is derived from both interviews and the web-survey. The result shows that medical device companies rely upon the ability to collaborate with the hospitals in different phases of their product development process and that there is an extensive need for a testbed structure amongst companies. The companies that collaborate with hospitals do it primarily because it makes their products more adaptive to functioning in the settings of healthcare, time to market and development costs can be decreased and it facilitates the process when validating the functionality of their products. Several companies have their ways of collaborating with hospital wards whilst others explicitly lack indispensable collaboration structures. The study has identified some companies which have shown interest in collaborating with Testbed Karolinska for telemedicine and eHealth and other ones whom wish to receive more information on what the testbed can offer them. In the commercialization plan it is suggested that Karolinska Testbed for telemedicine and eHealth shall focus on their niche and elaborate the competency which the companies doesn’t have. It is also suggested that the Testbed continues the work with developing the internal organization within Karolinska to enable efficient, flexible and qualitative collaboration between companies and the clinics at Karolinska University Hospital.

Metodologia – Como método optou-se por um estudo exploratório através de pesquisa bibliográfica buscando dados na literatura de experiências internacionais que pudessem fundamentar este estudo. Comparou-se os resultados de serviços de teletriagem implantados em 5 países. Aplicando a metodologia de Kim e Mauborgne buscou-se identificar o tipo de inovação introduzida e seu impacto nos custos e benefícios advindos da inovação. Resultados – Os resultados da análise dos dados mostram que os serviços de teletriagem das experiências internacionais conseguiram reduzir a utilização dos serviços de urgência e emergência e levaram os usuários a priorizar a atenção primária nos sistemas de saúde. Limitações – A principal limitação da pesquisa é que se baseia em experiências internacionais. Houve limitação de tempo e recursos para realização de testes laboratoriais, experimentais e para desenvolvimento de projetos pilotos que pudessem ser aplicado numa pesquisa de campo. Aplicabilidade do trabalho – Os resultados do trabalho permitiram recomendar sua aplicação em estudos com testes e pesquisas de campo, experimentos e simulações realísticas, em serviços de telessaúde no Brasil. Contribuições para a sociedade - O estudo sugere que os serviços de teletriagem teriam potencial de gerar benefícios para os usuários do Sistema Único de Saúde gerando educação em saúde, orientação para o autocuidado e fortalecimento das políticas de atenção primária em saúde. Originalidade – Pelo nosso conhecimento, este é o primeiro estudo que relaciona com teletriagem para os sistemas universais de saúde no Brasil. / Purpuse - This thesis of masters had as main objective to study the existence or not of benefits to the users in the adoption of the teletriage in the healthcare systems. Design/Methodology - As method, we opted for an exploratory study through bibliographical research seeking data in the literature of international experiences that could base this study. The results of teletriage services implemented in 5 countries were compared. Applying the Kim and Mauborgne methodology sought to identify the type of innovation introduced and its impact on the costs and benefits of innovation. Findings - The results of the data analysis show that the telephone triage services of the international experiences have managed to decrease the use of emergency/urgent care services and have led users to prioritize primary care in health systems. Research limitations - The main limitation of the research is that it is based on international experiences. There was limited time and resources for laboratory and experimental tests and pilot project development that could be applied in fieldwork. Practical implications - The results of the study allowed to recommend its application in studies with tests and fieldwork, experiments and realistic simulations, in telehealth services in Brazil. Social implications - The study suggests that teletriage services would have the potential to produce benefits for the users of the Brazilian Public Healthcare System, generating health education, orientation for self-care and strengthening of primary health care policies. Originality - To our knowledge, this is the first study that relates to telegraphy for universal health systems in Brazil.
