Use of a HAPI FHIR Server and Development of a Multi-user Web Interface for Visualization and Analysis of Data from Patients with Diabetes Mellitus

Estimates show that from 2019 to 2045, the number of people with Diabetes Mellitus could increase from 463 million to 700 million. Brazil follows this trend, and studies have shown that the country is the third country with the highest expenditure on diabetes. Studies with secure and interoperable databases are necessary to manage the disease. The Institute of Biomedical Engineering of the Federal University of Santa Catarina is developing the Screening for Diabetes Complications project, which seeks to collect, process, store and analyse data from patients with Diabetes Mellitus. This article presents the implementation of a HAPI FHIR server, which meets the HL7 FHIR communication standard, and an ElasticSearch server to complement and facilitate requests to the FHIR server. It also presents the development of a web interface, using an MVC architecture, for multiple users to visualize and analyze the collected data, meeting the General Data Protection Law requirements in Brazil.
