Digital transformation: How does physician’s work become affected by the use of digital health technologies?

Schultze, Jakob January 2021 (has links)
Digital transformation is evolving, and it is driving at the helm of the digital evolution. The amount of information accessible to us has revolutionized the way we gather information. Mobile technology and the immediate and ubiquitous access to information has changed how we engage with services including healthcare. Digital technology and digital transformation have afforded people the ability to self-manage in different ways than face-to-face and paper-based methods through different technologies. This study focuses on exploring the use of the most commonly used digital health technologies in the healthcare sector and how it affects physicians’ daily routine practice. The study presents findings from a qualitative methodology involving semi-structured, personal interviews with physicians from Sweden and a physician from Spain. The interviews capture what physicians feel towards digital transformation, digital health technologies and how it affects their work. In a field where a lack of information regarding how physicians work is affected by digital health technologies, this study reveals a general aspect of how reality looks for physicians. A new way of conducting medicine and the changed role of the physician is presented along with the societal implications for physicians and the healthcare sector. The findings demonstrate that physicians’ role, work and the digital transformation in healthcare on a societal level are important in shaping the future for the healthcare industry and the role of the physician in this future. / Den digitala transformationen växer och den drivs vid rodret för den digitala utvecklingen. Mängden information som är tillgänglig för oss har revolutionerat hur vi samlar in information. Mobila tekniker och den omedelbara och allmänt förekommande tillgången till information har förändrat hur vi tillhandahåller oss tjänster inklusive inom vården. Digital teknik och digital transformation har gett människor möjlighet att kontrollera sig själv och sin egen hälsa på olika sätt än ansikte mot ansikte och pappersbaserade metoder genom olika tekniker. Denna studie fokuserar på att utforska användningen av de vanligaste digitala hälsoteknologierna inom hälso- och sjukvårdssektorn och hur det påverkar läkarnas dagliga rutin. Studien presenterar resultat från en kvalitativ metod som involverar semistrukturerade, personliga intervjuer med läkare från Sverige och en läkare från Spanien. Intervjuerna fångar vad läkare tycker om digital transformation, digital hälsoteknik och hur det påverkar deras arbete. I ett fält där brist på information om hur läkare arbetar påverkas av digital hälsoteknik avslöjar denna studie en allmän aspekt av hur verkligheten ser ut för läkare. Ett nytt sätt att bedriva medicin och läkarens förändrade roll presenteras tillsammans med de samhälleliga konsekvenserna för läkare och vårdsektorn. Resultaten visar att läkarnas roll, arbete och den digitala transformationen inom hälso- och sjukvården på samhällsnivå är viktiga för att utforma framtiden för vårdindustrin och läkarens roll i framtiden.

A Conceptual Model of Behavior Change Progress for the Application within Coaching Systems to Support Sustainable Lifestyle Changes

Weck, Saskia January 2021 (has links)
Cardiovascular diseases and diabetes are increasing worldwide due to unhealthy lifestyle habits. Behavior change support systems (BCSS) are a new means of promoting a sustainable lifestyle change. These systems are more effective when behavior change theories are applied. The aim of this thesis to integrate well-known behavior change theories into a conceptual model of behavior change progress to form the basis for the BCSS. The research question of this thesis is: what parameters of behavior change should be included in a conceptual model of behavior change progress? The model was created by integrating concepts and their relationships from existing behavior change theories. Next, the model was the validated by experts in behavior change. The outcome is a conceptual framework that can be function as a tool for understanding causal relationship between behavior change concepts, for presenting feedback, and building automated assessments. Furthermore, the model extends already existing knowledge networks. / På grund av allmänhetens ohälsosamma vanor ökar Diabetes och kardiovaskulära sjukdomar i hela världen. Olika stödsystem för beteendeförändringar (BCSS) är ett nytt sätt att främja en hållbar livsstilsförändring. Dessa system är mer effektiva då beteendeförändringsteorier tillämpas. Syftet med denna avhandling är att integrera välkända teorier om beteendeförändring i en konceptuell modell av beteendeförändringsframsteg som kan ligga till grund för BCSS. Forskningsfrågan i denna avhandling är: Vilka parametrar för beteendeförändring ska ingå i en konceptuell modell för beteendeförändringsframsteg? Modellen skapades genom att integrera koncept och deras relationer från befintliga teorier om beteendeförändring. Resultatet är ett konceptuellt ramverk som kan fungera som ett verktyg för att förstå orsakssambandet mellan beteendeförändringsbegrepp, för att presentera feedback och för att bygga automatiserade bedömningar. Dessutom utökar modellen redan befintliga kunskapsnätverk.

Physical activity promotion in children using a novel smartphone game: a pilot randomized controlled trial

Lapusniak, Sam 16 March 2022 (has links)
Background: Regular physical activity (PA) is critical for children’s health and wellbeing. Despite the numerous health benefits, most Canadian children do not meet the Canadian PA guidelines. The emergence of the COVID-19 pandemic and social restrictions added new challenges to meeting the PA guidelines. Mobile health (mHealth) technology can be leveraged to promote PA among children. Combining gamification with mHealth interventions has the potential to further improve program effectiveness. Thus, “Draco” was developed as a virtual pet smartphone app to increase PA in children using self-determination theory as a framework to promote intrinsic motivation for PA. Objective: The primary objective is to evaluate the satisfaction and acceptability of the Draco app after four weeks. Secondary objectives include evaluating the preliminary effectiveness of the Draco app to improve average daily steps, average daily MVPA, perceived autonomy for PA, perceived competence for PA, and perceived relatedness to the app. Methods: 43 Canadian children, aged 8-14 years old, not meeting the Canadian PA guidelines of 60min of MVPA per day were randomly allocated to an intervention or control group. Participants in the control group used a step-tracking app for four weeks. Intervention participants were instructed to use the Draco app. Participants completed a baseline and follow-up questionnaire. PA outcomes were tracked using a Fitbit provided to each participant. Intrinsic PA motivation was assessed using an adapted version of the Intrinsic Motivation Inventory (IMI). Intrinsic motivation was assessed using the satisfaction subscale. Exit interviews were completed to determine app acceptability. Results: Participants demonstrated high levels of satisfaction and acceptability with the Draco app 2.83 (1.29). Intervention participants increased their average daily steps by 909 (1701). The control group increased their steps by 46 (1507). The Draco app had a small effect on promoting steps, MVPA, relatedness and small effects at increasing autonomy and competence. Conclusion: Participants demonstrated high levels of satisfaction and acceptability with the app. Participants in the intervention group showed greater increases in PA with small effect sizes. Preliminary evidence highlights the importance of tailoring game design to the users. Technical limitations impacted recruitment and user experiences. Additional development time should be taken to stabilize the app and add new game features for a definitive RCT. / Graduate

Att bryta osunda sociala medievanor : En studie om hur digitala interventioner upplevs i smarttelefoner

Åshamn, Albin, Wenander, Filip January 2023 (has links)
Tillgängligheten av sociala medier (SM) och ökningen av användandet har bidragit med konsekvenser som påverkar användarna negativt. Som konsekvens är det vanligt att användare försöker minska sin användning av sociala medier på egen hand genom att radera applikationer eller försöka avstå från att använda sina SM. För att minska stressen, behovet och den tid som användare spenderar på sina SM har de aktiverat digitala interventioner (DI) i sina smarttelefoner. DI i smarttelefonen är ett verktyg som är tänkt att upplysa och förhindra att användaren utför ett beteende som den vill motverka. I studien har upplevelser av att använda DI i smarttelefoner vid sociala medieanvändning undersökts med hjälp av en kvalitativ intervjustudie. I slutsatsen presenteras insikter om att användare upplever att DI kan vara ett bra hjälpmedel för förändring av sociala medievanor, men utmaningen är att det huvudsakliga ansvaret ligger på användaren. DI kan behöva erbjuda mer stöd för att undvika att deras användare faller tillbaka i osunda sociala medievanor. I studiens slutsats presenteras fem insikter om hur DI kan stödja användare till förändring av sociala medievanor. / The availability of social media (SM) and the increase in its usage have contributed to negative consequences affecting users. As a result, it is common for users to attempt to reduce their social media usage on their own by deleting applications or trying to abstain from using their SM. To reduce stress, the need, and the time spent on social media, users have activated digital interventions (DI) on their smartphones. DI on smartphones is a tool intended to inform and prevent the user from engaging in a behavior they wish to counteract. This study examined the experiences of using DI on smartphones in relation to social media usage through a qualitative interview study. The conclusion presents insights that users perceive DI as a helpful tool for changing social media habits, but the challenge lies primarily with the user. DI may need to offer more support to prevent their users from relapsing into unhealthy social media habits. The study's conclusion presents five insights on how DI can support users in changing their social media habits.

Die Generation Alpha der Digital Health Innovationen – Eine Fallstudie aus der Multiple Sklerose Versorgung

Schlieter, Hannes, Susky, Marcel, Richter, Peggy, Hickmann, Emily, Scheplitz, Tim, Burwitz, Martin, Ziemssen, Tjalf 01 March 2024 (has links)
Die digitale Transformation im Gesundheitswesen ermöglicht durch die Entwicklung zahlreicher neuer Technologien und Standards eine zunehmend individualisierte, bedarfsgerechte und berufsgruppenübergreifende Versorgung von Patienten. Diese neue Generation von Digital Health Innovationen – die Digital Health Generation Alpha (in Anlehnung an die korrespondierende Alterskohorte) – erfüllt Informations‑, Kommunikations- und Interoperabilitätsanforderungen entlang des gesamten Versorgungsprozesses, die aufgrund von abgegrenzten Leistungs- und Zuständigkeitsbereichen sowie Vergütungsregelungen oft eine unüberwindbare Hürde dargestellt haben. Im Beitrag werden mit der i) Pfadorientierung, ii) Patientenorientierung und -einbeziehung, iii) Qualitätsorientierung und iv) Integrationsfähigkeit vier zentrale Gestaltungsdimensionen von Digital Health Innovationen der Generation Alpha vorgestellt. Diese werden literaturgestützt aufgearbeitet und deren praktische Umsetzung anhand einer Fallstudie im Bereich der Versorgung von Patienten mit Multipler Sklerose aufgezeigt. Zentrale Leitfragen, konkrete Umsetzungsmaßnahmen und literaturgestützte Gestaltungsziele werden anhand eines prototypischen Vorgehensmodells beschrieben. Anhand der Fallstudie werden anschließend Implikationen für die zukünftige Digital Health Agenda abgeleitet, welche insbesondere für die Realisierung innovativer Werteversprechen und deren Integration in komplexe Zielumgebungen des Gesundheitswesens notwendig sind. / Through the development of numerous new technologies and standards the digital health care transformation progressively enables an individualized, need-based, and interprofessional treatment provision. The new generation of digital health innovations—in analogy to the age cohorts, the digital health generation alpha—can therefore fulfill information, communication, and interoperability tasks along the entire care process, that previously often represented an insurmountable challenge. The four design dimensions of digital health generation alpha are introduced: i) pathway orientation, ii) patient orientation and involvement, iii) quality orientation, and iv) integration capability. These are first discussed on basis of current literature and their practical utilization is then demonstrated in a case study on patients with multiple sclerosis. A process model for pathway development is presented that incorporates the four design dimensions and transforms a treatment process into a digital, participative, and integrated care model. Central guiding questions, concrete implementation measures and literature-based design goals are described based on the process model. Finally, implications for the future digital health agenda are derived, which are particularly necessary for the realization of innovative value propositions and their integration into complex healthcare target environments.

Digitala hälsotjänster som stöd till en hälsosam livsstil gällande kost, fysisk aktivitet och hälsosam vikt hos barn upp till 18 år : En strukturerad litteraturstudie / Digital health services as support for a healthy lifestyle regarding diet, physical activity and healthy weight in children up to 18 years of age : A structured literature study

Ebefors, Madeleine, Henriksson, Hanna January 2023 (has links)
Introduktion: Obesitas och övervikt har blivit en global epidemi. Det är fler som dör till följd av obesitas än av undervikt. Det är viktigt med tidig prevention för att förebygga övervikt och obesitas eftersom övervikt i tidig ålder ger större risk för övervikt och obesitas i vuxen ålder. Det finns cirka 370 000 hälsoappar för nedladdning, men lite forskning har gjorts om digitala hälsotjänster har effekt. Syfte: Att undersöka om digitala hälsotjänster kan stödja barn, upp till 18 år, att nå en hälsosam livsstil gällande kost och fysisk aktivitet samt hälsosam vikt. Metod: En strukturerad litteraturstudie där artiklarna analyserades tematisk. Resultat: Efter sökningar i CINAHL och Pubmed inkluderades 21 vetenskapliga originalartiklar. Artiklarna beskrev studier med barn upp till 18 år från 16 olika länder och med olika digitala hälsotjänster. Fyra teman identifierades: “Kostvanor”, “Fysisk aktivitet”, “BMI och BMI z-score”, samt “Tilltro till egen förmåga och engagemang hos barn och föräldrar”. Studien visade både signifikant och icke signifikant förändringar gällande kostförändring, fysisk aktivitet samt BMI eller BMI z-score. Vissa interventioner hade bestående effekt, andra inte. Familjerna hade en övergripande känsla av tillfredställelse att använda digitala hälsotjänster för att främja hälsosamma levnadsvanor och viktutveckling. Slutsats: Levnadsvanor gällande kost och fysisk aktivitet kan förändras med hjälp av digitala hälsotjänster. Med förändrade kostvanor och ändring av fysisk aktivitet kan det bidra till minskad förekomst av övervikt och obesitas. Förändringarna av levnadsvanor var dock inte alltid signifikanta eller bestående över tid. Mer forskning behövs. / Introduction: Obesity and overweight have become a global epidemic. More people die from obesity than from underweight. Early prevention is important to prevent overweight and obesity because overweight at an early age increase the risk of overweight and obesity in adulthood. There are about 370.000 health apps for download, but little research has been done on the effectiveness of digital health services. Aim: To investigate whether digital health service can support children up to 18 years of age to achieve a healthier lifestyle regarding eating habits and physical activity, and healthy weight. Methods: A structured literature review where the articles were analysed thematically. Results: After searches in CINAHL and PubMed, 21 scientific original articles were included. The articles described studies involving children up to 18 years from 16 different countries and with various digital health services. Four themes were identified: “Eating habits”, “Physical activities”, “BMI and BMI z-score”, and “Self-efficacy and engagement in children and parents”. The results showed both significant and non-significant changes regarding eating habits, physical activity, and BMI or BMI z-score. Some interventions had lasting effects, others did not. The families had an overall sense of satisfaction using digital health services to promote healthy lifestyle and weight development. Conclusion: Lifestyle habits related to eating habits and physical activity can be changed with the help of digital health services. These changes can contribute to reduced prevalence of overweight and obesity. However, the changes in lifestyle were not always significant or lasting over time. More research is required.

Bokningsväg till vårdbesök : Faktorer som har betydelse för hur patienter väljer att göra sin bokning – En mixad studiedesign / Booking route to healthcare visits : Factors that matters for how patients choose to make their booking - A mixed study design

Johansson Skrote, Maria, Thorold Nylin, Helén January 2023 (has links)
Introduktion: Digitala lösningar ökar inom vården och samhället. Digitala lösningar för vårdkontakt, bokning av tid samt vårdbesök finns idag och ökar i utbredning. I Vision ehälsa 2025 framhålls vikten av att hålla fokus på jämlikhet och jämställdhet när digitala verktyg utformas. Digitala lösningar kan vara en del i omställningen till en mer Nära Vård. För att kunna öka användandet av digitala lösningar inom hälso- och sjukvården kan det vara viktigt att förstå varför befintliga lösningar används eller inte används. Syfte: Syftet med studien var att fördjupa förståelsen kring hur bakomliggande faktorer såsom demografi, erfarenheter, inställningar och attityder påverkat valet av bokningssätt för patienter på Rörelse och Hälsa när de bokat förstagångsbesök till fysioterapeut. Metod: Studien genomfördes med mixad studiedesign. Registerdata användes för demografi och sambandsanalyser och intervjuer genomfördes för att få en fördjupad förståelse kring erfarenheter, inställningar och attityder. Resultat: Kvinnor använde sig i högre utsträckning av Webbtidbok än män. Patienter i ålderskategorin 20-29 år var gruppen som i högst utsträckning använde Webbtidbok, användandet minskade därefter i takt med stigande ålder. Låg ekonomisk standard och låg utbildningsnivå i vårdcentralsområdet korrelerade med lägre användning av Webbtidbok. Olika bokningsalternativ behöver finnas utifrån individers olika behov och förutsättningar. Kunskapen om Webbtidboken som alternativ var lägre än kunskapen om TeleQ. Slutsats: Ålder, kön, ekonomisk standard och utbildningsnivå kan påverka användandet av Webbtidbok. Det är av vikt att olika bokningsalternativ finns och att de är användarvänliga. Information om bokningsalternativ behöver förtydligas. / Introduction: Digital solutions are increasing in healthcare and society. Digital solutions for healthcare contact, appointment booking and healthcare visits exist today and are increasing in prevalence. It is important to maintain focus on equality and equity when digital tools are designed. Digital solutions can be a part of the transition to a more personcentred integrated care. In order to increase the use of digital solutions in healthcare, it may be important to understand why existing solutions are used or not. Aim: The aim of the study was to deepen the understanding of how underlying factors such as demographics, experiences and attitudes influenced the choice of booking method for patients booking their first appointment with a physiotherapist. Methods: The study was conducted with a mixed study design. Register data were used for demographic and correlational analyses, and interviews were conducted to gain a deeper understanding of experiences and attitudes. Results: Women used web-based self-scheduling to a greater extent than men. Patients in the age category 20-29 years used web-based self-scheduling to the highest extent, use subsequently decreased with increasing age. Low economic standard and low level of education in the Health Center area correlated with lower use online-booking. Different booking options need to be available based on individuals' different needs and qualifications. Knowledge of web-based self-scheduling was lacking. Conclusion: Age, gender, economic standard and level of education can affect the use of web-based self-scheduling. It is important that different user-friendly booking options are available. Information about booking options needs to be clarified.

Tissue Optics-Informed Hyperspectral Learning for Mobile Health

Sang Mok Park (16993905) 19 September 2023 (has links)
<p dir="ltr">Blood hemoglobin (Hgb) testing is a widely used clinical laboratory test for a variety of patient care needs. However, conventional blood Hgb measurements involve invasive blood sampling, exposing patients to potential risks and complications from needle pricks and iatrogenic blood loss. Although noninvasive blood Hgb quantification methods are under development, they still pose challenges in achieving performance comparable to clinical laboratory blood Hgb test results (i.e., gold standard). In particular, optical spectroscopy can provide reliable blood Hgb tests, but its practical utilizations in diagnostics are limited by bulky optical components, high costs, and extended data acquisition time. Mobile health (mHealth) or diagnostic colorimetric applications have a potential for point-of-care blood Hgb testing. However, achieving color accuracy for diagnostic applications is a complex matter, affected by device models, light conditions, and image file formats.</p><p dir="ltr">To address these limitations, we propose biophysics-based machine learning algorithms that combine hyperspectral learning and spectroscopic gamut-informed learning for accurate and precise mHealth blood Hgb assessments in a noninvasive manner. This method utilizes single-shot photographs of peripheral tissue acquired by onboard smartphone cameras. The palpebral conjunctiva (i.e., inner eyelid) serves as an ideal peripheral tissue site, owing to its easy accessibility, relatively uniform microvasculature, and absence of skin pigmentation (i.e., melanocytes). First, hyperspectral learning enables a mapping from red-green-blue (RGB) values of a digital camera into detailed hyperspectral information: an inverse mapping from a sparse space (tristimulus color values) to a dense space (multiple wavelengths). Hyperspectral learning employs a statistical learning framework to reconstruct a high-resolution spectrum from a digital photo of the palpebral conjunctiva, eliminating the need for complex and costly optical instrumentation. Second, comprehensive spectroscopic analyses of peripheral tissue are used to establish a unique blood Hgb gamut and design a diagnostic color reference chart highly sensitive to blood Hgb and peripheral perfusion. Informed by the domain knowledge of tissue optics and machine vision, the Hgb gamut-based learning algorithm offers device/light/format-agnostic color recovery of the palpebral conjunctiva, outperforming the existing color correction methods.</p><p dir="ltr">This mHealth blood Hgb prediction method exhibits comparable accuracy and precision to capillary blood sampling tests (e.g., finger prick) over a wide range of blood Hgb values, ensuring its reliability, consistency, and reproducibility. Importantly, by employing only a digital photograph with the Hgb gamut-learned color recovery, hyperspectral learning-based blood Hgb assessments allow noninvasive, continuous, and real-time reading of blood Hgb levels in resource-limited and at-home settings. Furthermore, our biophysics-based machine learning approaches for digital health applications can lay the foundation for the future of personalized medicine and facilitate the tempo of clinical translation, empowering individuals and frontline healthcare workers.</p>

Design of the DAVOS Study: Diabetes Smartphone App, a Fully Automatic Transmission of Data From the Blood Glucose Meter and Insulin Pens Using Wireless Technology to Enhance Diabetes Self-Management - A Study Protocol for a Randomized Controlled Trial

Grosser, Franziska, Herrmann, Sandra, Bretschneider, Maxi, Timpel, Patrick, Schildt, Janko, Bentrup, Markus, Schwarz, Peter E. H. 04 April 2024 (has links)
Background: In the treatment of diabetes mellitus, the challenge is to integrate adequate self-management into clinical care. Customization including goal setting, monitoring, and feedback could be achieved through digitization. Digital linking between different devices could simplify and promote self-management. The aim of this study is to evaluate the outcome of diabetes treatment assisted by a digital health application compared with standard diabetes therapy. - Methods: The DAVOS study is a 6-month-period prospective, multicentric, randomized controlled trial. In total, 154 diabetes patients (age ≥18; treated with insulin) will be recruited and randomized into control group or intervention group. Both groups will receive standard diabetes care. The intervention group will additionally use a diabetes app. HbA1c value will be monitored on three separate defined visits. Primary endpoint is the overall reduction of HbA1c value. Secondary endpoints (eg, usability of the app) will be determined through patient-reported outcome questionnaires. - Discussion: Through enhanced interaction of health care professionals, providers of the app, and patients, the study aims to demonstrate improvement in the self-management of diabetes. As part of the closure management, all patients will be invited to use the examined application after completion of the study. The DAVOS study will be conducted in accordance with the valid version of the present study protocol and the internationally recognized International Conference on Harmonization–Good Clinical Practice (ICH-GCP) Guidelines. Special attention will be paid to European, national, and regional requirements for the approval, provision, and use of medical devices. The study was registered in the German Register of Clinical Trials (DRKS) with number DRKS00025996.
