Ensino das habilidades básicas de colonoscopia: os padrões de qualidade e segurança podem ser atendidos em um centro universitário / Teaching basic colonoscopy skills: quality and safety standards can be fulfilled in an outpatient university center

ABSTRACT BACKGROUND: Recent studies have shown that endoscopy fellows can perform colonoscopy effectively and safely. However, little is known about the performance of surgical residents without prior knowledge of endoscopic techniques. OBJECTIVE: To assess whether quality indicators were met at an outpatient endoscopy center and whether surgical residents, without prior upper or lower endoscopy skills, could perform colonoscopy adequately. METHODS: A prospective non-randomized cohort study was undertaken. All exams were performed either by assistant physicians or by residents. Quality measures were compared between those groups. RESULTS: A total of 2720 colonoscopies were analyzed. In the resident group, we observed older patients (57.7±12.7 years vs 51.5±14.5 years, P<0.001), a higher prevalence of screening colonoscopies (52% vs 39.4%, P<0.001) and a higher prevalence of colorectal cancer (6.4% vs 1.8%, P<0.001). The cecal intubation rate was higher in the attending group (99.9% vs 89.3%; P<0.001). The polyp detection rate was 40.8%, and no differences were observed between the studied groups. The residents had a higher rate of perforation in all exams (0.4% vs 0%; P=0.02). Postpolypectomy bleeding and 7-day readmission rates were the same (0.2%). All readmissions in 7 days occurred due to low digestive bleeding, and none required intervention. CONCLUSION: Quality indicators were met at a university outpatient endoscopy center; however, medical residents achieved lower rates of cecal intubation and higher rates of perforation than the attending physicians.

RESUMO CONTEXTO: Estudos recentes mostraram que médicos em treinamento podem realizar a colonoscopia de maneira eficaz e segura. No entanto, pouco se sabe sobre a performance dos médicos residentes de cirurgia sem o conhecimento prévio das técnicas endoscópicas. OBJETIVO: Avaliar se os indicadores de qualidade foram atendidos em um centro de endoscopia ambulatorial e se os residentes de cirurgia, sem habilidades anteriores em endoscopia alta ou baixa, realizaram a colonoscopia de forma adequada. MÉTODOS: Foi realizado um estudo de coorte prospectivo não randomizado. Todos os exames foram realizados por médicos assistentes ou residentes. Os indicadores de qualidade foram comparados entre esses grupos. RESULTADOS: Um total de 2.720 colonoscopias foram analisadas. No grupo de médicos residentes, observamos pacientes mais velhos (57,7±12,7 anos vs 51,5±14,5 anos, P<0,001), maior prevalência de colonoscopias de rastreamento (52% vs 39,4%, P<0,001) e maior prevalência de câncer colorretal (6,4% vs 1,8%, P<0,001). A taxa de intubação cecal foi maior no grupo de médicos assistentes (99,9% vs 89,3%; P<0,001). A taxa de detecção de pólipos foi de 40,8% e não foram observadas diferenças entre os grupos estudados. Os médicos residentes tiveram maior índice de perfuração (0,4% vs 0%; P=0,02). O sangramento pós-polipectomia e as taxas de readmissão em 7 dias foram iguais (0,2%). Todas as readmissões em 7 dias ocorreram devido a hemorragia digestiva baixa e nenhuma intervenção foi necessária. CONCLUSÃO: Os indicadores de qualidade foram alcançados em um centro de endoscopia universitário; no entanto, os médicos residentes alcançaram taxas mais baixas de intubação cecal e taxas mais altas de perfuração do que os médicos assistentes.

Application of Quality Metrics in Food Inspection Laboratory Management / 中国药师

Because of the particularity and the complexity of integrated management of food, government regulators must perform the whole process of quality control and trace to evaluate and judge the merits of food instead of only depending on product standards.Quality metrics is a new concept for the food industry, and can be regarded as the comprehensive evaluation and measurement for product quality and the standard for judging the quality of food products.Request for Quality Metrics Guidance for Industry was issued, which not only established a new model for the quality control of pharmaceutical industry, but also provided a new way of quality management for the inspection organization.By introducing the contents of Request for Quality Metrics Guidance for Industry issued by the US FDA, on the basis of summarization and thought, the quality management and evaluation of pharmaceutical industry was compared, and the feasibility and applicability of quality metrics management in inspection and testing field, especially in food testing field was evaluated.In this paper, the concept of quality metrics was extended to the level of food inspection laboratory management with hope to provide ideas for the future development of food quality management model.
