- Data Integration in the Brazilian Public Health System for Tuberculosis: Use of the Semantic Web to Establish InteroperabilityPublication . Pellison, Felipe Carvalho; Rijo, Rui Pedro Charters Lopes; Lima, Vinicius Costa; Crepaldi, Nathalia Yukie; Bernardi, Filipe Andrade; Galliez, Rafael Mello; Kritski, Afrânio; Abhishek, Kumar; Alves, DomingosBackground: Interoperability of health information systems is a challenge due to the heterogeneity of existing systems at both the technological and semantic levels of their data. The lack of existing data about interoperability disrupts intra-unit and inter-unit medical operations as well as creates challenges in conducting studies on existing data. The goal is to exchange data while providing the same meaning for data from different sources. Objective: To find ways to solve this challenge, this research paper proposes an interoperability solution for the tuberculosis treatment and follow-up scenario in Brazil using Semantic Web technology supported by an ontology. Methods: The entities of the ontology were allocated under the definitions of Basic Formal Ontology. Brazilian tuberculosis applications were tagged with entities from the resulting ontology. Results: An interoperability layer was developed to retrieve data with the same meaning and in a structured way enabling semantic and functional interoperability. Conclusions: Health professionals could use the data gathered from several data sources to enhance the effectiveness of their actions and decisions, as shown in a practical use case to integrate tuberculosis data in the State of São Paulo.
- Establishment of Access Levels for Health Sensitive Data Exchange through Semantic WebPublication . Lima, Vinicius Costa; Alves, Domingos; Pellison, Felipe Carvalho; Yoshiura, Vinicius Tohoru; Crepaldi, Nathalia Yukie; Rijo, Rui, Rui Pedro Charters LopesData exchange in health information systems must be carefully planned and needs to be protected from unauthorized access due to sensibility of stored content. Security aspects like authentication, authorization and encryption must be considered in this context. The main goal of this article is to present the implementation of security mechanisms to a semantic API that allows data extraction from a regional health information system designed to create notifications and to follow patients diagnosed with Tuberculosis. Data semantically tagged will be mapped individually to several access levels. It will be showed how external systems can connect, authenticate and retrieve only authorized data that are classified in the scope of its maximum access level.
- From guidelines to decision-making: using mobile applications and semantic web in the practical case of guides to support patientsPublication . Lima, Vinicius Costa; Rijo, Rui Pedro Charters Lopes; Pellison, Felipe Carvalho; Lima, Ricardo Roberto de; Correia, Ricardo João Cruz; Giuriati, Henrique Tresmonde; Alves, DomingosThe use of guidelines, procedures and recommendations is very common and also a simple way to structure, organize and retrieve relevant information that, in turn, may impact on patient care. However, it is necessary to expedite the retrieval of stored information. By simplifying the access to the desired data, it is possible to make the process practical, fast and intuitive for the health professional. The main goal of this article is to present a development approach for a project that proposes decision-making tools, based on guidelines, to assist health professionals in the care process of patients with specific diseases (or a combination of them). These tools will be developed for use on mobile devices and as a web-based system, which will transform a passive and declarative manual into an interactive tool that will provide not only data and information, but also knowledge through semantic web paradigm. Further, we will show an example of usability and feasibility of the proposed application through a functional prototype developed for Android platform.
