Health data is one of the most valuable data and highly sensitive. Its careful handling is essential in today' s digitalized world and cloud technology use for sharing. Health Information Systems facilitate the storage and accessibility of health data for better care along the patient path. As the integration of all historical patient data, the Electronic Health Record is at the heart of health data management. The centralization of stored health data represents a single point of failure and trust, making data exchange across institutions difficult and insecure. Blockchain technology builds on consensus mechanisms and immutable chains of blocks for validating and securing data transactions as a modern decentralized approach. The application of blockchain technology for Electronic Health Records is promising but still a young concept. Due to the wide range of discussion, this paper aims at identifying risks by using blockchain technology in the eHealth sector. Based on a systematic literature review, various authors' argumentations and findings are examined and concluded to set up the empirical study. The semistructured qualitative interview study aims to find out the threats of blockchain. The paper concludes with an overall discussion and some implementation recommendations.
In this paper, the authors discussed Enterprise Interoperability (EI) in Mergers and Acquisitions (M&A) transactions focusing on ERP systems. Essential connections to practice are drawn through a discussion of use cases with experts from the fields of M&A, IT, and ERP. The research question is defined as: What are the core influencing factors determining interoperability profiles, and what will the future look like regarding the ERP dimension? Based on eleven experts and qualitative content analysis, relevant findings on EI implementation scenarios are extracted. There are different approaches to achieve Enterprise Interoperability, depending on the context of the M&A transaction. Finally, the crucial decision factors are given in the findings and show the future development of ERP systems integrations. Current results suggest that fast and easy EI is a critical requirement to meet the increasing need for flexibility and ERP systems are at the core of these developments.
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.
