ontologies unifying electronic health records(EHR) to share in distributed ledger technology (DLT)

Abstract

This article presents an overview of the state of the art in the thematic ontology as an information tool for the Electronic Patient Record (EHR) to be made available at Distributed Ledger Technology. In a growing context and varied volume of information on people's health, it is a challenge for the Electronic Patient Record to follow the patient wherever he goes. The general objective of the study is to obtain an overview of research carried out on ontologies to organize the information in the Electronic Patient Record to be made available at Distributed Ledger Technology, from the perspective of Information Science and its interdisciplinary relations with areas of Health and Science of Computing. The methodological trajectory uses a literature review in the three areas of knowledge, followed by a quantitative and exploratory research of dissertations, theses and articles indexed and retrieved from national and international search engines, totaling seven, for the period from 2015 to 2020. The results obtained with the search strategies indicate little exploration of ontologies to organize the information of the countless and diversified Electronic Patient Records to be shared in the new digital informational environment, at Distributed Ledger Technology. It is concluded that there is a need for more studies to articulate, in an interdisciplinary way, the interoperability of clinical systems through ontology for later use of Distributed Ledger Technology in the provision of patient health information.
