ABSTRACT

BACKGROUND: The number and specificities of telehealth service units that expanded their services and diversified with the COVID-19 pandemic in Brazil need to be discovered. The objective of this manuscript is to present a methodology for the diagnostic evaluation of 19 telehealth units from different regions of the country for federal governmental decision-making. METHODS: A cross-sectional quantitative and qualitative study was carried out in the form of a census based on administrative records with an online survey and in-depth interviews with local telehealth managers. RESULTS: Despite the discontinuity of regular funding, the results point to a diversity of initiatives and advances. Citizenship, sustainability, security, and budget management are recurring themes in the maturity analysis of telehealth services after the advent of the pandemic. CONCLUSION: It is necessary for Brazil to build a resilient model of the maturity of telehealth services that contemplates the different regional scenarios.

ABSTRACT

This article describes a proposed framework called Telehealth Service Maturity Model (TMSMM.br) for evaluating the current stage of telehealth centers in the Brazilian context. The steps included literature review, compilation and interpretation, data collection instrument, survey with center coordinators, model development, and evaluation process. The review resulted in 857 quality aspects for telehealth services, grouped into 12 themes with 34 topics. TMSMM.br consists of defining 3 foundational dimensions (themes, services, stages) and provides a standardized set of 200 requirements ordered across 5 thematic domains (structure, organization, user, operation and community) for 8 services (consultation, consultation, diagnosis, treatment and referral, education and training, social control and communication, healthcare network, and research, development, and innovation). TMSMM.br enables telehealth centers to identify and compare essential characteristics and their maturity stages.

ABSTRACT

In the last decade, industrial environments have been experiencing a change in their control processes. It is more frequent that control strategies adopt Artificial Neural Networks (ANNs) to support control operations, or even as the main control structure. Thus, control structures can be directly obtained from input and output measurements without requiring a huge knowledge of the processes under control. However, ANNs have to be designed, implemented, and trained, which can become complex and time-demanding processes. This can be alleviated by means of Transfer Learning (TL) methodologies, where the knowledge obtained from a unique ANN is transferred to the remaining nets reducing the ANN design time. From the control viewpoint, the first ANN can be easily obtained and then transferred to the remaining control loops. In this manuscript, the application of TL methodologies to design and implement the control loops of a Wastewater Treatment Plant (WWTP) is analysed. Results show that the adoption of this TL-based methodology allows the development of new control loops without requiring a huge knowledge of the processes under control. Besides, a wide improvement in terms of the control performance with respect to conventional control structures is also obtained. For instance, results have shown that less oscillations in the tracking of desired set-points are produced by achieving improvements in the Integrated Absolute Error and Integrated Square Error which go from 40.17% to 94.29% and from 34.27% to 99.71%, respectively.

ABSTRACT

Industrial environments are characterised by the non-lineal and highly complex processes they perform. Different control strategies are considered to assure that these processes are correctly performed. Nevertheless, these strategies are sensible to noise-corrupted and delayed measurements. For that reason, denoising techniques and delay correction methodologies should be considered but, most of these techniques require a complex design and optimisation process as a function of the scenario where they are applied. To alleviate this, a complete data-based approach devoted to denoising and correcting the delay of measurements is proposed here with a two-fold objective: simplify the solution design process and achieve its decoupling from the considered control strategy as well as from the scenario. Here it corresponds to a Wastewater Treatment Plant (WWTP). However, the proposed solution can be adopted at any industrial environment since neither an optimization nor a design focused on the scenario is required, only pairs of input and output data. Results show that a minimum Root Mean Squared Error (RMSE) improvement of a 63.87% is achieved when the new proposed data-based denoising approach is considered. In addition, the whole system performance show that similar and even better results are obtained when compared to scenario-optimised methodologies.

ABSTRACT

The evolution of industry towards the Industry 4.0 paradigm has become a reality where different data-driven methods are adopted to support industrial processes. One of them corresponds to Artificial Neural Networks (ANNs), which are able to model highly complex and non-linear processes. This motivates their adoption as part of new data-driven based control strategies. The ANN-based Internal Model Controller (ANN-based IMC) is an example which takes advantage of the ANNs characteristics by modelling the direct and inverse relationships of the process under control with them. This approach has been implemented in Wastewater Treatment Plants (WWTP), where results show a significant improvement on control performance metrics with respect to (w.r.t.) the WWTP default control strategy. However, this structure is very sensible to non-desired effects in the measurements-when a real scenario showing noise-corrupted data is considered, the control performance drops. To solve this, a new ANN-based IMC approach is designed with a two-fold objective, improve the control performance and denoise the noise-corrupted measurements to reduce the performance degradation. Results show that the proposed structure improves the control metrics, (the Integrated Absolute Error (IAE) and the Integrated Squared Error (ISE)), around a 21.25% and a 54.64%, respectively.

ABSTRACT

Wastewater treatment plants (WWTPs) form an industry whose main goal is to reduce water's pollutant products, which are harmful to the environment at high concentrations. In addition, regulations are applied by administrations to limit pollutant concentrations in effluent. In this context, control strategies have been adopted by WWTPs to avoid violating these limits; however, some violations still occur. For that reason, this work proposes the deployment of an artificial neural network (ANN)-based soft sensor in which a Long-Short Term Memory (LSTM) network is used to generate predictions of nitrogen-derived components, specifically ammonium ( S N H ) and total nitrogen ( S N t o t ). S N t o t is a limiting nutrient and can therefore cause eutrophication, while nitrogen in the S N H form is toxic to aquatic life. These parameters are used by control strategies to allow actions to be taken in advance and only when violations are predicted. Since predictions complement control strategies, the evaluation of the ANN-based soft sensor was carried out using the Benchmark Simulation Model N.2. (BSM2) and three different control strategies (from low to high control complexity). Results show that our proposed method is able to predict nitrogen-derived products with good accuracy: the probability of detecting violations of BSM2's limits is 86%⁻94%. Moreover, the prediction accuracy can be improved by calibrating the soft sensor; for example, perfect prediction of all future violations can be achieved at the expense of increasing the false positive rate.

ABSTRACT

Background and Introduction: In Brazil, the Telemedicine University Network (RUTE) initiative promotes collaboration between university hospitals, teaching hospitals, health professionals, and students using information and communication technology infrastructure to support special interest groups (SIGs) in health care. Health professionals in institutions belonging to RUTE plan a program of video conferences and/or web conferences to discuss specific themes. This article presents the results of an analysis of collaboration in these SIGs. Materials and Methods: This study uses descriptive statistical analysis and visualization of data contained in management reports provided by RUTE national coordinators for the period between 2007 and 2016 to evaluate the extent of participation in SIGs between institutions associated with RUTE. In this data visualization, we employ concepts from social network theory. Results: The analysis identified the most influential institutions as measured by social network theory metrics. A small number of institutions were found to have many participating SIGs, but most had only a few participating institutions (more than 130 institutions have only one participating SIG). Over the study period, a significant quantitative growth in collaboration occurred, increasing from 21 institutions and 92 participating SIGs in 2007 to 380 institutions and 1,912 participating SIGs in 2016. Conclusion: The growth in collaboration within the network indicates increasing interest and participation in telehealth initiatives in Brazil.

ABSTRACT

RESUMO Introdução A Rede Universitária de Telemedicina (Rute) é uma iniciativa que visa, no Brasil, promover a integração em telemedicina e telessaúde de hospitais universitários, hospitais certificados de ensino, faculdades de Medicina e profissionais da área da saúde por meio de infraestrutura de tecnologia da informação e comunicação e dos grupos de interesse especial (SIGs). Nesses grupos, que são criados e coordenados por instituições integrantes da Rute, profissionais de saúde e pesquisadores planejam uma agenda de videoconferências e/ou webconferências para debater temas específicos. Este artigo apresenta resultados da classificação dos SIGs da Rute em grupos homogêneos com base em sua produção em comunicação, cooperação e coordenação (3C). Métodos Foi realizado um inquérito com coordenadores dos SIGs entre abril e maio de 2016. A classificação dos SIGs em grupos homogêneos considerou as atividades desenvolvidas na rede entre 2007 e o momento da aplicação do inquérito. O estudo é retrospectivo, baseado em dados históricos das unidades, instituições e SIGs. Os coordenadores de 71 SIGs Rute foram convidados a responder. Desses, 45 SIGs ativos responderam ao inquérito de avaliação por completo e foram considerados nas análises. Resultados Quase um terço dos coordenadores respondentes (35%) declarou que seus SIGs atuam no eixo ensino, 21% atuam nos eixos de assistência e pesquisa, desenvolvimento e inovação, enquanto 12% atuam em gestão e 11% em avaliação. Foi feita a classificação dos SIGs em três grupos homogêneos - colaboração emergente, colaboração em desenvolvimento e colaboração plena - e identificado que, fora das sessões, 71% dos 45 SIGs (11 do grupo colaboração emergente e 20 do grupo em desenvolvimento) usam correio eletrônico como principal ferramenta de comunicação. Quatro SIGs do grupo colaboração plena indicaram: uso de serviço de mensagens instantâneas (1 SIG), site próprio (1 SIG) e redes sociais (2 SIGs). Conclusão Os resultados deste estudo podem não aferir com precisão a real produção e colaboração que os SIGs desenvolvem. Sugere-se, portanto, apreciar esta análise como um ponto de partida ou um referencial para a comunidade Rute. Porém, os resultados indicam que o desenvolvimento da colaboração na Rute e nos SIGs verificado nas análises é significativo, apontando uma evolução positiva para a Rute quanto ao interesse, participação e divulgação de ações em telemedicina e telessaúde no País.


ABSTRACT Introduction The Telemedicine University Network (RUTE) in Brazil is an initiative that promotes collaboration between university hospitals, teaching hospitals, health professionals, and students using information and communication technology infrastructure to support special interest groups (SIGs) in health care. Health professionals in RUTE-member institutions plan a program of video conferences and/or web conferences to discuss specific themes. This article presents the results of an analysis of the collaboration between the Special Interest Groups (SIGs) of the Telemedicine University Network (RUTE) considering the SIGs production in communication, cooperation and coordination (3C). Methods A survey was applied to SIG coordinators between April and May 2016. The classification of SIGs into homogeneous groups considered the activities developed in the network between 2007 and the time of the survey application. The study is retrospectively based on historical data from units, institutions and SIGs. The coordinators of 71 RUTE SIGs were invited to respond. Of those, forty-five active SIGs responded to the evaluation survey in its entirety and were considered in the analyses. Results Almost one third of the respondent coordinators (35%) stated that their SIG works in the education axis, 21% work in the care and research, development and innovation axes, while 12% work in management and 11% in evaluation. The SIGs were grouped into three homogeneous categories: emergent collaboration, collaborative development, and full collaboration, and it was identified that 71% of the 45 SIGs (11 in the emerging and 20 developing groups) use email as the main extra-session communication tool. Four SIGs from the full collaboration group reported: use of instant messaging service (1 SIG), own website (1 SIG) and social networks (2 SIGs). Conclusion The results of this study suggests may not accurately gauge the actual production and collaboration that SIGs develop and this analysis can be considered as a starting point or as a reference for the RUTE community. However, the results suggest significant growth in collaboration between RUTE-member SIGs, indicating a positive trend for the RUTE regarding the interest, participation and dissemination of actions in telemedicine and telehealth in the country.

ABSTRACT

Abstract. OBJECTIVE: To present a cognitive map to support the radiological diagnosis of solitary bone tumors, as well as to facilitate the determination of the nature of the tumor (benign or malignant), in pediatric patients. MATERIALS AND METHODS: We selected 28 primary lesions in pediatric patients, and we identified the findings typically associated with each of the diagnoses. The method used for the construction of the final cognitive map was the Bayesian belief network model with backward chaining. RESULTS: We developed a logical, sequential structure, in the form of a cognitive map, based on the Bayesian belief network model, with the intention of simulating the sequence of human thinking, in order to minimize the number of unnecessary interventions and iatrogenic complications arising from the incorrect evaluation of bone lesions. CONCLUSION: With this map, it will be possible to develop an application that will provide support to physicians and residents, as well as contributing to training in this area and consequently to a reduction in diagnostic errors in patients with bone lesions.

ABSTRACT

RESUMO Fundamentos As doenças da pele são causas comuns da procura de atendimento na atenção primária em saúde, e a maioria desses atendimentos é realizada por médicos não dermatologistas. Em geral, o aprendizado insuficiente na graduação se reflete na atuação clínica e, consequentemente, em atendimentos referenciados, resultando em aumento de custo. Teledermatologia é a prática da dermatologia com uso de tecnologias de informação e sistemas de comunicação para a troca de informações médicas de um paciente entre médico não dermatologista e um dermatologista (teledermatologia secundária) - nos mesmos ou em diferentes momentos e em diferentes localizações geográficas. A teledermatologia secundária promete ser melhor, mais barata e mais rápida, embora as evidências não sejam suficientes em relação ao curso clínico da doença. Objetivo Revisar a literatura sobre as evidências científicas da teledermatologia secundária na prática médica. Método Revisão da literatura, entre 1999 e 2014, de ensaios clínicos, estudos observacionais, revisões e revisões sistemáticas identificados no PubMed sobre a teledermatologia secundária na prática médica. Além desses estudos, foram incluídos ensaios clínicos mais recentes realizados no Brasil sobre acurácia ou concordância de diagnóstico da teledermatologia secundária da base bibliográfica Lilacs durante o mesmo período e outros estudos relevantes de outras bases em relação à educação médica e dados demográficos. Resultados Foram incluídos 11 estudos mais recentes e/ou relevantes quanto à amostra e ao padrão clínico de diagnóstico. O resultado desta revisão foi dividido em quatro tópicos: eficiência da teledermatologia na atenção primária em saúde; acurácia concordância ou confiabilidade do diagnóstico da teledermatologia na atenção primária em saúde em relação à consulta presencial; satisfação e qualidade de vida do paciente; custo da teledermatologia na atenção primária em saúde. A maioria desses estudos relatou boa eficiência e acurácia de diagnóstico com diminuição dos custos e melhora da qualidade de vida dos pacientes, em especial os de área rural. Conclusão O acesso à dermatologia não pode ocorrer sem gestão. Devemos identificar situações em que a teledermatologia secundária funcione melhor, como em áreas remotas ou carentes, permitindo ao paciente acesso aos dermatologistas. A eficiência e acurácia de diagnóstico da teledermatologia secundária são inferiores às da consulta presencial, mas superior à da consulta dermatológica oferecida por médicos não dermatologistas.


ABSTRACT Background Skin diseases are a common cause of service demand on the primary health care system and the majority of these services are not performed by dermatologists. In general, insufficient undergraduate training is reflected in clinical performance and, consequently, in the referenced services, resulting in increased cost. Teledermatology is the practice of dermatology using information technology and communication systems. It consists of information exchanges between a dermatologist and general practitioners (secondary teledermatology) - either simultaneously or sequentially and in different geographical locations. Secondary Teledermatology promises a more efficient, reasonable and faster treatment in dermatological care, despite insufficient evidence regarding the clinical course of the disease. Objective To review the scientific literature which presents evidence of secondary teledermatology in medical practice. Method Review of the literature from 1999 to 2014 on clinical trials, observational studies, reviews and systematic reviews identified in PubMed on secondary. teledermatology in medical practice. In addition to these studies, we have included more recent clinical trials in Brazil on the accuracy or agreement of diagnoses made through secondary teledermatology found in the Lilacs bibliographic database, during the same period as well as other relevant studies from other databases regarding medical education and demographics. Results The 11 most recent and/or relevant studies in relation to the sample and clinical standard of diagnosis were included. The result of this review was divided into four topics: teledermatology efficiency in primary health care; accuracy, compliance or reliability of the teledermatology diagnosis in primary health care in relation to face-to-face dermatology consultation; patient satisfaction and quality of life; and cost of teledermatology in primary health care. Most of these studies reported good efficiency and diagnostic accuracy with lower costs and better quality of life for patients, in particular for those living in rural areas. Conclusion Dermatology is inaccessible without management. We must identify situations in which secondary teledermatology works best, as in remote or underserved areas, allowing patients to have access to dermatologists. The efficiency and accuracy of the diagnoses made through secondary teledermatology is inferior to face-to-face dermatological consultation, but more efficient than the dermatological visits provided by general practitioners.

ABSTRACT

Objetivo: Investigar o uso de técnicas para extração de conhecimento de diagnósticos provenientes de laudos de biópsia renal. Métodos: Foram aplicadas técnicas de extração de conhecimento em um conjunto de laudos de biópsia renal do Serviço de Patologia do Hospital do Rim e Hipertensão, São Paulo. Resultados: Foram extraídos 694 diagnósticos completos diferentes do conjunto de 3.018 laudos. Foi obtida uma árvore de três níveis diagnósticos e uma nuvem de palavras com os termos extraídos dos diagnósticos. A extração de terminologia resultou em 206 termos candidatos únicos que ocorreram 20.599 vezes no corpus avaliado. Conclusão: O resultado da extração de terminologia apresentou-se como satisfatório para criar uma taxonomia sobre biópsia renal. A árvore com ligação entre diagnósticos pode auxiliar novos profissionais em treinamento na área de patologia para confecção dos laudos.


Objective: To present techniques for extracting knowledge of diagnosis from renal biopsy reports. Methods: Knowledge extraction techniques were applied in a set of reports of the Pathology service of the Kidney and Hypertension Hospital. Results: From 3,018 reports 694 different complete diagnoses were extracted. A tree with three diagnostic levels and a word cloud with terms extracted from diagnoses were obtained. The terminology extraction resulted in 206 unique candidate terms that occurred 20,599 times in the evaluated corpus. Conclusion: The results of terminology extraction is suitable to create a taxonomy about renal biopsy. Trees with link between diagnoses can help new professionals in the area of pathology for writing the reports.

ABSTRACT

This study aims to identify whether the use of concept mapping (CM) strategy assists a student to extend and revise their expertise in oncology and analyze the abilities developed in a student in order to go through theoretical to practical knowledge. This study is descriptive and qualitative, with 20 undergraduate students of the Undergraduate Nursing Course of Paulista School of Nursing of Federal University of São Paulo, Brazil. The critical incident technique and content analysis were used. There were 12 categories represented by facilities, difficulties, and learning applicability in oncology provided by CM strategy during the surgical and clinical nursing discipline. The graphics resource, CMapTools®, and the clinical case data arranged in mapping for resolution generated an active search and exercise of self-learning in oncology. Despite the challenges of the use of CM as a teaching strategy-pedagogical, the results suggested an increase of autonomy and clinical reasoning in nursing practice.

ABSTRACT

In Brazil the Telemedicine University Network (Rede Universitária de Telemedicina RUTE) is an initiative that among others promotes collaboration between university hospitals, universities, and health professionals through information technology infrastructure and special interest groups (SIGs) support. This paper presents results of analyses on collaboration during implementation and coordination activities of RUTE SIGs. This study is based on descriptive statistics and data visualization previously collected by RUTE national coordination relative to the status in July 2014. The analysis through collaboration graph identified the strongest collaboration RUTE units. The graph also highlights the collaborative relationship of RUTE units in form of communities, the most collaborative with each other in a communion in the same SIGs, and the less the collaborative units in the network. It should be stated that the most active units are also the oldest in the community.

ABSTRACT

The entire kidney transplantation process in Brazil is defined through laws, decrees, ordinances, and resolutions, but there is no defined theoretical map describing this process. From this representation it's possible to perform analysis, such as the identification of bottlenecks and information and communication technologies (ICTs) that support this process. The aim of this study was to analyze and represent the kidney transplantation workflow using business process modeling notation (BPMN) and then to identify the ICTs involved in the process. This study was conducted in eight steps, including document analysis and professional evaluation. The results include the BPMN model of the kidney transplantation process in Brazil and the identification of ICTs. We discovered that there are great delays in the process due to there being many different ICTs involved, which can cause information to be poorly integrated.

ABSTRACT

Studies show a gap between the expressions commonly used by health consumers and health professionals. To bridge this gap, consumer health vocabularies are presented as a solution. The aim of this paper is to describe an on-going project to create a consumer health vocabulary (CHV) in the Brazilian Portuguese language. This project will be developed in three phases: terms extraction and connection to compose a CHV graph structure, human validation, and computacional application development. We expect to make a CHV beta version (including approximately 5,000 valid consumer terms stored in a database graph) available. This project can contribute to the improvement of CHVs.
