    Abstract Background: Contact tracing apps are potentially useful tools for supporting national COVID-19 containment strategies. Various national apps with different technical design features have been commissioned and issued by governments worldwide.
    Objective: Our goal was to develop and propose an item set that was suitable for describing and monitoring nationally issued COVID-19 contact tracing apps. This item set could provide a framework for describing the key technical features of such apps and monitoring their use based on widely available information.
    Methods: We used an open-source intelligence approach (OSINT) to access a multitude of publicly available sources and collect data and information regarding the development and use of contact tracing apps in different countries over several months (from June 2020 to January 2021). The collected documents were then iteratively analyzed via content analysis methods. During this process, an initial set of subject areas were refined into categories for evaluation (ie, coherent topics), which were then examined for individual features. These features were paraphrased as items in the form of questions and applied to information materials from a sample of countries (ie, Brazil, China, Finland, France, Germany, Italy, Singapore, South Korea, Spain, and the United Kingdom [England and Wales]). This sample was purposefully selected; our intention was to include the apps of different countries from around the world and to propose a valid item set that can be relatively easily applied by using an OSINT approach.
    Results: Our OSINT approach and subsequent analysis of the collected documents resulted in the definition of the following five main categories and associated subcategories: (1) background information (open-source code, public information, and collaborators); (2) purpose and workflow (secondary data use and warning process design); (3) technical information (protocol, tracing technology, exposure notification system, and interoperability); (4) privacy protection (the entity of trust and anonymity); and (5) availability and use (release date and the number of downloads). Based on this structure, a set of items that constituted the evaluation framework were specified. The application of these items to the 10 selected countries revealed differences, especially with regard to the centralization of the entity of trust and the overall transparency of the apps' technical makeup.
    Conclusions: We provide a set of criteria for monitoring and evaluating COVID-19 tracing apps that can be easily applied to publicly issued information. The application of these criteria might help governments to identify design features that promote the successful, widespread adoption of COVID-19 tracing apps among target populations and across national boundaries.

    Abstract Radiology has a reputation for having a high affinity to innovation - particularly with regard to information technologies. Designed for supporting the peculiarities of radiological diagnostic workflows, Radiology Information Systems (RIS) and Picture Archiving and Communication Systems (PACS) developed into widely used information systems in hospitals and form the basis for advancing the field towards automated image diagnostics. RIS and PACS can thus serve as meaningful indicators of how quickly IT innovations diffuse in secondary care settings - an issue that requires increased attention in research and health policy in the light of increasingly fast innovation cycles. We therefore conducted a retrospective longitudinal observational study to research the diffusion dynamics of RIS and PACS in German hospitals between 2005 and 2017. Based upon data points collected within the "IT Report Healthcare" and building on Rogers' Diffusion of Innovation (DOI) theory, we applied a novel methodological technique by fitting Bayesian Bass Diffusion Models on past adoption rates. The Bass models showed acceptable goodness of fit to the data and the results indicated similar growth rates of RIS and PACS implementations and suggest that market saturation is almost reached. Adoption rates of PACS showed a slightly higher coefficient of imitation (q = 0.25) compared to RIS (q = 0.11). However, the diffusion process expands over approximately two decades for both systems which points at the need for further research into how innovation diffusion can be accelerated effectively. Furthermore, the Bayesian approach to Bass modelling showed to have several advantages over the classical frequentists approaches and should encourage adoption and diffusion research to adapt similar techniques.

    Abstract Hospital CIOs play a central role in the adoption of innovative health IT. Until now, it remained unclear which particular conditions constitute their capability to innovate in terms of intrapersonal as well as organisational factors. An inventory of 20 items was developed to capture these conditions and examined by analysing data obtained from 164 German hospital CIOs. Principal component analysis resulted in three internally consistent components that constitute large portions of the CIOs innovation capability: organisational innovation culture, entrepreneurship personality and openness towards users. Results were used to build composite indicators that allow further evaluations.

    Abstract Background: While aiming for the same goal of building a national eHealth Infrastructure, Germany and the United States pursued different strategic approaches - particularly regarding the role of promoting the adoption and usage of hospital Electronic Health Records (EHR).
    Objective: To measure and model the diffusion dynamics of EHRs in German hospital care and to contrast the results with the developments in the US.
    Materials and methods: All acute care hospitals that were members of the German statutory health system were surveyed during the period 2007-2017 for EHR adoption. Bass models were computed based on the German data and the corresponding data of the American Hospital Association (AHA) from non-federal hospitals in order to model and explain the diffusion of innovation.
    Results: While the diffusion dynamics observed in the US resembled the typical s-shaped curve with high imitation effects (q = 0.583) but with a relatively low innovation effect (p = 0.025), EHR diffusion in Germany stagnated with adoption rates of approx. 50% (imitation effect q = -0.544) despite a higher innovation effect (p = 0.303).
    Discussion: These findings correlate with different governmental strategies in the US and Germany of financially supporting EHR adoption. Imitation only seems to work if there are financial incentives, e.g. those of the HITECH Act in the US. They are lacking in Germany, where the government left health IT adoption strategies solely to the free market and the consensus among all of the stakeholders.
    Conclusion: Bass diffusion models proved to be useful for distinguishing the diffusion dynamics in German and US non-federal hospitals. When applying the Bass model, the imitation parameter needs a broader interpretation beyond the network effects, including driving forces such as incentives and regulations, as was demonstrated by this study.

    Abstract Health information technology (IT) is a decisive factor for hospitals in optimizing the provision of healthcare services and many countries are interested in understanding, monitoring, and benchmarking the mechanisms of digital transformation on the national level. Part of this effort is the use of science-based maturity models to measure the level of digitization of healthcare institutions. The results of the maturity measurement are finally disseminated through science-practice dialogue concepts. The aim of this study is to develop and evaluate a technical platform to support this science-practice dialogue in the context of nationwide health IT monitoring in hospitals. Here users, the Chief Information Officer (CIO) in hospitals, provide data on the status of health IT in their institutions through a structured self-assessment on the platform. The data is analyzed and processed with scientific instruments, i.e. (1) according to scientifically established procedures of quantitative methodology and (2) in the context of current scientific findings and research questions. The individual findings are presented to the user on a dashboard. The platform comprises the six components , , , , and . All of them were developed pursuing the design science methodology. The evaluation of the platform revealed that it supports CIOs in IT strategic management. Usability tests showed that the platform increases user satisfaction. Within this study we could show how a science-practice dialogue to generate practical implications in the context of a nationwide health IT monitoring can be technically implemented.

    Title translation Verbesserung des IT-Monitorings im Gesundheitswesen durch ein elektronisches System zum Austausch zwischen Wissenschaft und Praxis
    Abstract Die Gesundheits-Informationstechnologie (IT) ist für Krankenhäuser ein entscheidender Faktor bei der Optimierung der Bereitstellung von Gesundheitsdienstleistungen. Viele Länder sind daran interessiert, die Mechanismen der digitalen Transformation auf nationaler Ebene zu verstehen, zu überwachen und zu benchmarken. Teil dieser Bemühungen ist die Nutzung von wissenschaftlich fundierten Reifegradmodellen, um den Digitalisierungsgrad der Gesundheitseinrichtungen zu messen. Die Ergebnisse der Reifegradmessung werden schließlich durch Konzepte des Wissenschaft-Praxis-Dialogs in die Breite getragen. Ziel dieser Studie sind die Entwicklung und Evaluation einer technischen Plattform zur Unterstützung dieses Wissenschaft-Praxis-Dialogs im Rahmen eines bundesweiten Gesundheits-IT-Monitorings in Krankenhäusern. Dabei stellen die Nutzer, die Chief Information Officer (CIO) in den Krankenhäusern, Daten zum Status der Gesundheits-IT in ihren Einrichtungen durch eine strukturierte Selbsteinschätzung auf der Plattform zur Verfügung. Die Daten werden mit wissenschaftlichen Instrumenten, das heißt (1) nach wissenschaftlich etablierten Verfahren der quantitativen Methodik und (2) im Kontext aktueller wissenschaftlicher Erkenntnisse und Fragestellungen, analysiert und verrechnet und den Anwendern in einem Dashboard individualisiert präsentiert.
    Die Plattform besteht aus den sechs Komponenten Datenerfassung, Indikatoren und Scores, Algorithmen, Speicherung, Datenzusammenstellungspipeline und Dashboard. Sie wurde nach den Prinzipien von Design Science entwickelt. Eine Evaluation der Plattform zeigt, dass sie Chief Information Officer bei der strategischen Steuerung ihrer IT unterstützt. Usability-Tests weisen darauf hin, dass die Plattform die Zufriedenheit bei den Nutzern steigert. In dieser Studie konnten wir zeigen, wie ein Wissenschaft-Praxis-Dialog zur Generierung praktischer Implikationen im Rahmen eines landesweiten Gesundheits-IT-Monitorings technisch umgesetzt werden kann.

    Abstract Background: Diabetes mellitus is one of the most prominent examples of chronic conditions that requires an active patient self-management and a network of specialists.
    Objectives: The aim of this study was to analyze the user and legal requirements and develop a rough technology concept for a secure and patient-centered exchange platform.
    Methods: To this end, 14 experts representing different stakeholders were interviewed and took part in group discussions at three workshops, the pertinent literature and legal texts were analyzed.
    Results: The user requirements embraced a comprehensive set of use cases and the demand for "one platform for all" which is underlined by the right for data portability according to new regulations. In order to meet these requirements a distributed ledger technology was proposed.
    Conclusion: We will therefore focus on a patient-centered application that showcases self-management and exchange with health specialists.

    Abstract Background: IT is getting an increasing importance in hospitals. In this context, major IT decisions are often made by CEOs who are not necessarily IT experts.
    Objectives: Therefore, this study aimed at a) exploring different types of IT decision makers at CEO level, b) identifying hypotheses if trust exists between these different types of CEOs and their CIOs and c) building hypotheses on potential consequences regarding risk taking and innovation.
    Methods: To this end, 14 qualitative interviews with German hospital CEOs were conducted to explore the research questions.
    Results: The study revealed three major types: IT savvy CEOs, IT enthusiastic CEOs and IT indifferent CEOs. Depending on these types, their relationship with the CIO varied in terms of trust and common language. In case of IT indifferent CEOs, a potential vicious circle of lack of IT knowledge, missing trust, low willingness to take risks and low innovation power could be identified.
    Conclusion: In order to break of this circle, CEOs seem to need more IT knowledge and/or greater trust in their CIO.

    Abstract Distributed and heterogeneous data must be integrated for health services research in a way, which is open to new requirements and easily expandable for new data sources. For data integration in the health services research domain, mainly data warehouses have been used that model data either as a dimensional or an entity-attribute-value (EAV) model. However, these data models are either not flexible enough or lack data management capabilities, which makes longitudinal data analyses more difficult. We have extended the EAV approach with data vault modelling and hereby modelled the data structures of the hospital quality reports by the Gemeinsamer Bundesauschuss (G-BA) and integrated data from the years 2011 to 2015 accordingly. This makes it possible to historicise metadata of features, in particular those of quality indicators, and establishes a high degree of extensibility towards new heterogeneous data sources. The proposed approach allows a free selection of the abstraction level for the entities to be modelled, so that a completely generic EAV model with historicised metadata can be created.
