- 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.
- Data quality in tuberculosis: the case study of two ambulatories in the state of São Paulo, BrazilPublication . Yamaguti, Verena Hokino; Vicentine, Fernanda Bergamini; Lima, Inacia Bezerra de; Zago, Laís; Rodrigues, Lídia Maria Lourençon; Alves, Domingos; Crepaldi, Nathalia Yukie; Rijo, Rui Pedro Charters Lopes; Ruffino-Netto, AntónioTuberculosis is the second leading responsible cause of death from infectious diseases. Tuberculosis effective control and related activities depends on the use of different systems that aim to assist and monitor patients through managing their health data, and facilitating the activities of several health professionals. However, we noticed disparities in the information provided by some systems, which can negatively impact planning and decision-making. The study is defined as a quantitative and descriptive study of patients’ data during the treatment of tuberculosis in two different ambulatories. The data was collected from four different sources, including three information systems and the local patient archive in the ambulatories. Collected data was cleansed and standardized for semantic and structure, which allowed data comparison and analysis for its reliability and completeness. Low reliability scores are due to the absence of a semantic standard and the careless validation on recording of data by the professionals. Therefore, this study was able to effectively detect inconsistencies between the different data sources, stressing the need of health standards for data consistency, interoperability, and promoting data quality.
- 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.
- Satisfaction evaluation of health professionals in the usability of software for monitoring the tuberculosis treatmentPublication . Crepaldi, Nathalia Yukie; Lima, Inácia Bezerra de; Vicentine, Fernanda Bergamini; Rodrigues, Lídia Maria Lourençon; Yamaguti, Verena Hokino; Sanches, Tiago Lara Michelin; Ruffino-Netto, Antonio; Alves, Domingos; Rijo, Rui Pedro Charters LopesThe evaluation of health software from the point of view of the health professionals is critical for its success. The work aims to present one of the steps, in this case the usability evaluation, of a more comprehensive protocol of how health software can be evaluated. A software for monitoring tuberculosis treatment (SISTB) was used to test the proposed protocol. The Computer System Usability Questionnaire was the instrument chosen to evaluate software usability. Its adaptation to Portuguese (from Brazil) was performed through three pretests, which obtained high internal consistency, using the Cronbach alpha reliability analysis. SISTB was deployed in three of four referral outpatient clinics for tuberculosis, in the city of Ribeirão Preto, state of São Paulo, Brazil. After three months, health professionals answered the questionnaire. All outpatients presented satisfactory results for usability, showing that the satisfaction degree with software is good and that three months are sufficient for adaptation in relation to the SISTB use. Despite the good acceptance, some suggestions have been proposed, showing that software should be in constant development to facilitate the service of those who use it.
- Towards a Clinical Trial Protocol to Evaluate Health Information Systems: Evaluation of a Computerized System for Monitoring Tuberculosis from a Patient Perspective in BrazilPublication . Crepaldi, Nathalia Yukie; Bezerra de Lima, Inacia; Vicentine, Fernanda Bergamini; Rodrigues, Lídia Maria Lourençon; Sanches, Tiago Lara Michelin; Ruffino-Netto, Antonio; Alves, Domingos; Rijo, Rui, Rui Pedro Charters LopesAssessment of health information systems consider different aspects of the system itself. They focus or on the professional who will use the software or on its usability or on the software engineering metrics or on financial and managerial issues. The existent approaches are very resources consuming, disconnected, and not standardized. As the software becomes more critical in the health organizations and in patients, becoming used as a medical device or a medicine, there is an urgency to identify tools and methods that can be applied in the development process. The present work is one of the steps of a broader study to identify standardized protocols to evaluate the health information systems as medicines and medical devices are evaluated by clinical trials. The goal of the present work was to evaluate the effect of the introduction of an information system for monitoring tuberculosis treatment (SISTB) in a Brazilian municipality from the patients’ perspective. The Patient Satisfaction Questionnaire and the Hospital Consumer Assessment of Healthcare Providers and Systems were answered by the patients before and after the SISTB introduction, for comparison. Patients from an outpatient clinic, formed the control group, that is, at this site was not implanted the SISTB. Descriptive statistics and mixed effects model were used for data analysis. Eighty-eight interviews were conducted in the study. The questionnaire’s results presented better averages after the system introduction but were not considered statistically significant. Therefore, it was not possible to associate system implantation with improved patient satisfaction. The HIS evaluation need be complete, the technical and managerial evaluation, the safety, the impact on the professionals and direct and/or indirect impact on patients are important. Developing the right tools and methods that can evaluate the software in its entirety, from the beginning of the development cycle with a normalized scale, are needed.
