Accuracy of wearable electronic device compared to manual and automatic methods of blood pressure determination.

Blood pressure (BP) is the main biomarker for monitoring patients, as its lack of control above values considered normal is a modifiable risk factor for target organ damage. The aim of this study is to evaluate the accuracy of the wearable electronic device photoplethysmography technology (PPG) Samsung Galaxy Watch 4 in determining BP in young patients compared to manual and automatic methods of BP determination. This is a quantitative and cross-sectional study, following validation protocols for wearable devices and BP measurement. It was carried out with twenty healthy young adults, in which BP was measured using four instruments, namely, standard sphygmomanometer device (manual), automatic arm oscillometric device (reference), wrist oscillometric device, and Smartwatch PPG. Eighty systolic blood pressure (SBP) and diastolic blood pressure (DBP) readings were observed. SBP means manual 118 ± 2.20,arm 113 ± 2.54, wrist 118 ± 2.51, and PPG (smartwatch) 113 ± 2.58. Among means, arm and PPG difference is 0.15, arm and wrist 4.95, arm and manual 4.45 wrist with PPG. The mean DBP manual 76.7 ± 1.84, arm 73.6 ± 1.92, wrist 79.3 ± 1.87, and PPG 72.2 ± 1.38. Among means, the difference between the arm and PPG is 1.4 and arm and hand 3.5 mmHg. The correlation shows PPG with manual, arm, and wrist. There was a strong SBP correlation and a moderate DBP correlation between the methods tested, evidencing the accuracy of the PPG smartwatch in relation to the reference method.

O Caminho se Faz ao Caminhar: Novas Perspectivas da Educação Médica no Contexto da Pandemia / The Path Is Made by Walking it: New Perspectives for Medical Education in the Pandemic Context

Resumo: Introdução: Este relato aborda os aspectos relacionados à experiência vivenciada durante a pandemia da Covid-19, na vigência da suspensão das atividades presenciais da Universidade do Estado do Rio Grande do Norte (UERN), e apresenta a estratégia desenvolvida por meios digitais para mitigar os impactos no processo formativo de futuros médicos e na atenção à saúde de mulheres e adolescentes. Participaram três professoras do Departamento de Ciências Biomédicas (DCB-UERN), 31 estudantes do curso de Medicina, 12 residentes do Programa de Residência Médica em Ginecologia e Obstetrícia (PRMGO) da UERN/Prefeitura Municipal de Mossoró (PMM), dois técnicos e 150 pacientes, em espaços virtuais e nos cenários de práticas do PRMGO da UERN/PMM, em ambulatórios de ginecologia e obstetrícia (GO) da FACS/UERN e no Programa de Extensão Pró-Mulher. Relato de Experiência: Realizaram-se 18 webinários multiprofissionais, além da utilização de um aplicativo para acompanhamento no pré-natal, redes sociais como ferramentas de promoção da saúde e desenvolvimento de pesquisa e um instrumento de avaliação da qualidade da informação em saúde. Discussão: Ações de apoio ao estudante e o estímulo ao desenvolvimento docente contribuem para a redução dos impactos da pandemia, nas dimensões da educação e da atenção à saúde. O envolvimento de estudantes na produção de materiais educativos e a realização de palestras e sessões demonstrativas por meios remotos podem promover a aprendizagem e o desenvolvimento de competências médicas. Entretanto, o uso das tecnologias digitais na educação médica e na atenção à saúde implica enorme responsabilidade ética, social e política perante a salvaguarda dos direitos humanos, devendo ser assegurada a utilização adequada e segura das tecnologias. Conclusão: Em cenários desafiadores no interior do Rio Grande do Norte, na Região Nordeste, é possível promover a aprendizagem significativa e contribuir para o desenvolvimento de competências médicas mediante a inclusão digital genuína, com ações integradoras e interdisciplinares, cujos benefícios poderão ser ampliados por políticas afirmativas que contemplem as características e os indicadores regionais, de modo a diminuir as assimetrias.

Abstract: Introduction: This study reports on an experience during the COVID-19 pandemic, where in view of the suspension of face-to-face activities at the Universidade do Estado do Rio Grande do Norte (UERN), a strategy was developed using digital resources, aimed at mitigating the negative impacts on the training of future doctors and health care of women and adolescents. The work involved the participation of three professors from the Department of Biomedical Sciences (DCB - UERN), 31 medical students, 12 residents of the Medical Residency Program in Gynecology and Obstetrics (PRMGO) at UERN / Prefeitura Municipal de Mossoró (PMM), two technicians and 150 patients, in virtual spaces and in the practice scenarios of the PRMGO, the Gynecology and Obstetrics (GO) Outpatient Clinic at FACS/UERN, and the Pro-Women Outreach Program. Experience report: 18 multi-disciplinary webinars were held; an application for monitoring prenatal care was used, as well as social networks as tools for promoting health, research development and an instrument for assessing the quality of the health information. Discussion: Actions to support students and encourage teacher development contribute to reducing the impacts of the pandemic on aspects of education and health care. Student engagement, the development of educational products, and holding remote lectures and demonstration sessions can promote learning and the development of medical skills, but, in to guarantee the safeguarding of human rights, the use of digital technologies in medical education and health care implies great ethical, social and political responsibility, and so the appropriate and safe use of technologies must be ensured. Conclusion: In challenging scenarios in the interior of Rio Grande do Norte, Northeast Brazil, it was possible to promote meaningful learning and contribute to the development of medical skills through genuine digital inclusion, based on integrative, interdisciplinary actions, the benefits of which can be broadened by affirmative policies that address regional characteristics and indicators, and reduce asymmetries.
