A Fuzzy Rule-Based Model for Remote Monitoring of Preterm in the Intensive Care Unit of Hospitals

The use of Remote patient monitoring (RPM) systems to monitor critically ill patients in the Intensive Care Unit (ICU) has enabled quality and real-time healthcare management. Fuzzy logic as an approach to designing RPM systems provides a means for encapsulating the subjective decision-making process of medical experts in an algorithm suitable for computer implementation. In this paper, a remote monitoring system for preterm in neonatal ICU incubators is modeled and simulated. The model was designed with 4 input variables (body temperature, heart rate, respiratory rate, and oxygen level saturation), and 1 output variable (action performed represented as ACT). ACT decides whether an alert is generated or not and also determines the message displayed when a notification is required. ACT classifies the clinical priority of the monitored preterm into 5 different fields: code blue, code red, code yellow, code green, and code black. The model was simulated using a fuzzy logic toolbox of MATLAB R2015A. About 216 IF_THEN rules were formulated to monitor the inputs data fed into the model. The performance of the model was evaluated using the confusion matrix to determine the model’s accuracy, precision, sensitivity, specificity, and false alarm rate. The experimental results obtained shows that the fuzzy-based system is capable of producing satisfactory results when used for monitoring and classifying the clinical statuses of neonates in ICU incubators.

Prototype of a computer system for managing data and video colonoscopy exams

OBJECTIVE: Develop a prototype using computer resources to optimize the management process of clinical information and video colonoscopy exams. MATERIALS AND METHODS: Through meetings with medical and computer experts, the following requirements were defined: management of information about medical professionals, patients and exams; video and image captured by video colonoscopes during the exam, and the availability of these videos and images on the Web for further analysis. The technologies used were Java, Flex, JBoss, Red5, JBoss SEAM, MySQL and Flamingo. RESULTS AND DISCUSSION: The prototype contributed to the area of colonocospy by providing resources to maintain the patients' history, tests and images from video colonoscopies. The web-based application allows greater flexibility to physicians and specialists. The resources for remote analysis of data and tests can help doctors and patients in the examination and diagnosis. CONCLUSION: The implemented prototype has contributed to improve colonoscopy-related processes. Future activities include the prototype deployment in the Service of Coloproctology and the utilization of this model to allow real-time monitoring of these exams and knowledge extraction from such structured database using artificial intelligence.

MATERIAIS E MÉTODOS: Por meio de reuniões com especialistas médicos e computacionais, definiram-se os seguintes requisitos: gestão de informações sobre profissionais médicos, pacientes e exames complementares; aquisição dos vídeos e captura de imagens a partir do videocolonoscópio durante a realização desse exame, e a disponibilidade por meio da Web para análise posterior dessas imagens. As tecnologias aplicadas foram: Java, Flex, JBOSS, Red5, JBOSS SEAM, MySQL e Flamingo. RESULTADOS E DISCUSSÃO: O protótipo contribuiu para a área de colonocospia disponibilizando recursos para manutenção de histórico de pacientes, exames e imagens. O acesso à aplicação, por meio de browser, permite maior flexibilidade aos médicos e especialistas. Os recursos para análise remota de dados e exames podem auxiliar médicos e pacientes na realização de exames e diagnósticos. CONCLUSÃO: O protótipo implementado contribuiu para melhoria de processos relacionados a exames de videocolonoscopia. Trabalhos futuros incluem implantação do protótipo no serviço de coloproctologia, bem como a extensão do modelo para o acompanhamento dos exames em tempo real e extração de conhecimento dessa base de dados estruturada por meio de inteligência artificial.
