Prontuário eletrônico odontológico com uso da tecnologia blockchain

Abstract

The storage of patient data in medical records is performed centrally, making it difficult for patients to access this confidential data, which is notoriously detrimental to the control of this patient over dental records and the detailed monitoring of the steps of a given dental treatment. The control of dental records, for this reason, is the exclusive prerogative of dentists. The patient, in many situations, is totally unaware of the notes recorded in the chart itself. In this sense, this research aims to identify studies on the application of blockchain technology in the health area and, through this information, define the requirements of a prototype of an electronic dental record that provides for the use of blockchain technology. This is an integrative review. The guiding question of the research was: what are the applications of blockchain technology in the management of electronic health records? The bibliographic search took place in 2022, using publications (articles, dissertations and theses) from the last 10 years, in the electronic databases MEDLINE, Web of Science and Scopus. In addition, requirements and usage scenarios were identified. The integrative review retrieved 18,728 studies, using the descriptors “blockchain” or “smart contracts”. Through the application of the concepts of exclusion, inclusion and quality, 83 studies were retrieved and used in this review. The description of the scenarios helped to understand the needs, requirements and acceptability of the project and its feasibility. The blockchain platform provides the development of a decentralized application, in which the pattern of data transactions is not controlled by any intermediary organization. Entities transaction data is stored in a decentralized database in a verifiable, secure, immutable and transparent manner with time stamp and other relevant details. The number of studies on blockchains in healthcare applications continues to increase, although some applications of the technology still have imitations that remain unsolved. Despite the excellent potential and the great interest in blockchain technology, we assess that its impact on the storage of patient records remains in the documentation phase and research and clinical care applications still need to be developed. Most studies based on blockchain solutions continue in the form of new concepts and in some cases, operationally based on restricted user data. The future of blockchain technology that eliminates middlemen has immense potential to exert a significant positive effect on the storage of patient data in healthcare
