The utilization of blockchain has previously been studied mainly in cryptocurrencies and in the digital economy and financial world related applications. However, it has been noted recently that technology has great potential in areas that could benefit society at larger scale also, in activities that do not involve money, currency, trade, financial markets or other economic activities. This bachelor\u2019s thesis focuses on the possibilities of utilizing blockchain in the healthcare sector, more specifically in the management of electronic health records (EHR). The aim of the thesis is to map the current state of research related to the subject and to find out what challenges are currently associated with electronic health record systems (EHRS), what added value the main features of blockchain technology could bring to electronic health record management and what challenges still need to be addressed in order to truly realize its potential. The study found that current electronic health record systems face certain challenges in terms of system interoperability as well as data privacy and security. In addition, many of these systems are centralized in a single location, which may pose risks, for example in the case of data breaches or natural disasters. However, traditional database systems are still the most commonly used structure in the system architecture of electronic health record systems. The features of decentralization, immutability,\nverifiability, transparency, and encryption algorithms enabled by block-chain technology were seen as a possible solution to address some of those key challenges electronic health record systems are facing. However, challenges in blockchain\u2019s scalability and storage capacity management, as well as in data security and interoperability, as well as in cultural and social adoption, have so far been identified hampering its larger-scale adoption in this area. This bachelor\u2019s thesis has been implemented as a literature review, in which material that meets the criteria of scientific research has been searched from selected databases with selected and defined keywords.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2021-07-02T09:45:00Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-07-02T09:45:00Z (GMT).
