RESUMO
Abstract Background Arterial hypertension affects around 30% of the Brazilian adult population, showing a direct and progressive relationship with an increased risk of cardiovascular diseases (CVDs). In this context, adjustments in the calibration and physical constitution of sphygmomanometers are essential conditions for obtaining correct blood pressure (BP) measurements. Objectives Analyze the profile and quality of sphygmomanometers used in various sectors of a health education institution in Belo Horizonte, Minas Gerais. Methods The present study conducted a cross-sectional, observational, and non-interventional study to assess adherence to various quality parameters of the sphygmomanometers available in the outpatient clinic, emergency department, and ward of an educational institution in the municipality of Belo Horizonte. Results We analyzed 78 devices, in which high rates of adherence were identified for velcro/pins, 93.5% (73/78); bulbs/rubbers, 92.1% (70/76); valves, 93.4% (71/76); the seal of the National Institute of Metrology, Quality, and Technology (INMETRO), 97.4% (76/78); and the clock, 92.1% (70/76). However, these parameters showed no statistical significance. Institutions (hospital/outpatient clinic) recorded higher calibration rates, 75% (39/52, p<0.001), in accordance with the deadlines stipulated by INMETRO, and the cuff/equipment compatibility showed its highest value (52%) among students (32/61, p = 0.004). Conclusion Our study showed that 38.4% (30/78) of the devices did not presented some type of inadequacy, with outpatient-owned devices had the highest compliance rate (p = 0.015). These findings are worrisome, as they can lead to inaccurate BP measurements.
RESUMO
Fundamento: A hipertensão arterial é o principal fator de risco cardiovascular. A qualidade técnica dos esfigmomanômetros é condição fundamental para obtenção da correta medida da pressão arterial. Objetivos: Avaliar o perfil dos esfigmomanômetros disponíveis nos serviços de urgências de Belo Horizonte, Minas Gerais. Métodos: Realizamos um estudo transversal, observacional e não intervencionista para avaliar o perfil dos esfigmomanômetros disponíveis nos prontos atendimentos de adultos de hospitais públicos e privados do município de Belo Horizonte. Avaliamos 337 aparelhos de 25 hospitais, sendo 15 públicos (do total de 16) e 10 privados (do total de 12). Resultados: Foram observadas inadequações dos equipamentos em relação à validação pelo Instituto Nacional de Metrologia, Qualidade e Tecnologia INMETRO, em 26% (88/337) dos equipamentos; calibração vencida em 39% (132/337) e não correspondência de marca aparelho/braçadeira em 54% (188/337). Em 13 dos 25 hospitais (52%), não havia disponibilidade de manguitos para braços de diferentes tamanhos além do padrão. Houve superioridade de adequação dos aparelhos aneroides e de mercúrio dos hospitais privados (p = 0,038 e p < 0,001, respectivamente) e dos eletrônicos nos públicos (p < 0,001). Conclusão: Conclui-se que 78% dos esfigmomanômetros disponíveis nos serviços de urgência/emergência de uma das maiores capitais brasileiras apresentavam inadequações técnicas, e em metade dos serviços não havia manguitos de diferentes tamanhos. Tal fato representa um alerta para a situação dos equipamentos disponíveis para atendimento da população no país
Background: Hypertension is the main risk factor for cardiovascular diseases. Technical quality of sphygmomanometers is a prerequisite for the correct measurement of arterial pressure. Objectives: To evaluate sphygmomanometers available in emergency services in the city of Belo Horizonte, Brazil. Methods: We performed a cross-sectional, observational, non-interventional study to evaluate characteristics of the sphygmomanometers available in adult emergency services of public and private hospitals in the city of Belo Horizonte, Brazil. We evaluated 337 sphygmomanometers of 25 hospitals 15 (of 16) public hospitals and 10 (of 12) private hospitals. Results: Twenty-six percent (88/337) of devices were considered inadequate regarding the INMETRO (National Institute of Metrology, Quality and Technology) standards, 39.2% (132/337) for calibration dates, and 54% (188/337) for the mismatching between cuff's and device's brands. In 13 of 25 hospitals (52%), there were no spare cuffs in different sizes for different arm circumferences. Higher adequacy was found for aneroid and mercury sphygmomanometers used in private hospitals (p = 0.038 and p < 0.001, respectively) and electronic devices used in public hospitals (p < 0.001) compared with others.Conclusion: Seventy-eight percent of sphygmomanometers available in emergency services had technical inadequacies, and half of these services had no spare cuffs in different sizes available. These findings serve as a warning of the conditions of the equipment used in healthcare services provided to the general population in Brazil
