In the course of digitization in healthcare, personal health records (PHRs) are handled as a key solution. Despite the indisputable benefits, the adoption of PHRs is hampered by data security and data privacy concerns. Blockchain technology offers promising potential to address these issues by enabling secure transactions of sensitive data. With regards to PHRs, the blockchain can be used to manage the access to health-related data. Besides existing generic PHR architectures, we systematically identified issues for the healthcare sector that need to be considered for the development of a PHR. We subsequently derived eight meta-requirements that were consolidated into three design principles. Within a 1-year design science research project, we developed the blockchain-secured PHR prototype, OSHealthRec, and evaluated the system in four evaluation cycles. The findings of our research are twofold. On the one hand, we contribute to the design knowledge base by presenting three design principles. On the other hand, we present the development of a real, operational blockchain-secured PHR and the findings from its continuous evaluation, which may serve as useful advice for further solutions.
ZusammenfassungLehrkräfte können auf eine Vielzahl von etablierten Unterrichtsmethoden zurückgreifen, um kooperatives Lernen in den Präsenzunterricht zu integrieren. Im Distanzunterricht während der Corona-Pandemie werden diese Methoden jedoch häufig nicht eingesetzt. Dadurch gehen das gemeinschaftliche, strukturierte Lernen und die damit einhergehenden positiven Effekte auf die Schülerinnen und Schüler verloren. Eine State-of-the-Art-Analyse zeigt, dass kaum technische Lösungen existieren, die methodenbasiertes, kooperatives Lernen in einem Distanzunterricht unterstützen – und falls doch, handelt es sich um sehr spezielle Lösungen für die Umsetzung einer konkreten Unterrichtsmethode. Wir schlagen daher das Konzept eines Smart Cooperative Distance Learning Systems vor. Dabei handelt es sich um ein Multiagentensystem in einer Cloud, welches insbesondere die methodenbasierte, kooperative Ausführung von Lerneinheiten unterstützt. Ein Szenario dient zur Veranschaulichung des Smart Cooperative Distance Learning Systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
