A cloud service for graphical user interfaces generation and electronic health record storage

Abstract

The development of archetype-based Health Information Systems (HIS) allows the creation of interoperable mechanisms for the Electronic Health Record (EHR) as well as improvements for application maintenance and upgrades. However, we identified a lack of an approach or tool to build dynamic archetype-based data schema in heterogeneous database. This article presents a cloud service able to build Graphical User Interface (GUI) and data schema for use in the healthcare sector. Using data attributes, terminologies and constraints extracted from EHR archetypes, it dynamically generates GUI and data schema in heterogeneous databases. In order to persist EHR data, we used the concept of polyglot persistence to store structured data in a relational database, while non-structured data is stored in a NoSQL database. Finally, we validated the proposed service in a hospital located in northeastern Brazil and demonstrate how health professionals can build GUI for use in the healthcare sector without depending on a software development team.
