RESUMO

Analisar o conhecimento sobre prevenção de quedas em trabalhadores da construção civil com base em indicadores nos resultados de enfermagem NOC. Estudo transversal com 173 trabalhadores da construção civil realizado em 2013. Construiu-se um instrumento com indicadores NOC Conhecimento: prevenção de quedas de acordo às normas regulamentadoras do Ministério do Trabalho e Previdência Social. A magnitude dos indicadores construiu-se em uma escala Likert, pontuação de 1 a 5. Na análise estatística utilizou-se o teste não paramétrico de Kruskal-Wallis. Parecer favorável do Comitê de Ética em Pesquisa nº 369.361. Identificou-se diferença significativamente estatística entre o nível de escolaridade dos trabalhadores com relação aos indicadores NOC. No fator Quanto ao uso correto de dispositivos de segurança obteve-se que 20,8% com ensino fundamental completo tinham conhecimento substancial. Compete à enfermagem do trabalho promover estratégias visando à promoção da saúde do trabalhador nos ambientes de trabalho, para torná-los seguros e livres de acidentes.

To analyze the knowledge about fall prevention in construction workers based on indicators in NOC. A cross-sectional study with 173 construction workers conducted in 2013. An instrument with NOC indicators was built. Knowledge: fall prevention according to the regulatory norms of the Ministry of Labor and Social Security. The magnitude of the indicators was built on a Likert scale, scoring from 1 to 5. The non-parametric Kruskal-Wallis test was used in the analysis. Favorable opinion of the Research Ethics Committee nº 369.361. A statistically significant difference was found between the educational level of workers in relation to NOC indicators. In the factor Regarding the correct use of security devices it was obtained that 20.8% with complete elementary education had substantial knowledge. It is incumbent upon work nursing to promote strategies aimed at promoting worker health in work environments, to make them safe and free from accidents.

RESUMO

FUNDAMENTO: Há grande controvérsia quanto ao diagnóstico de Insuficiência Renal Aguda (IRA), existindo mais de 30 diferentes definições. OBJETIVO: Avaliar a incidência e os fatores de risco para desenvolvimento de IRA no pós-operatório de cirurgia cardíaca de acordo com os critérios RIFLE, AKIN e KDIGO, e comparar o poder prognóstico desses critérios. MÉTODOS: Estudo de corte transversal que incluiu 321 pacientes (62 [53 - 71] anos, 140 homens) consecutivamente submetidos a cirurgia cardíaca entre junho de 2011 e janeiro de 2012. Os pacientes foram acompanhados por 30 dias, com vistas ao desenvolvimento de um desfecho composto (mortalidade, necessidade de diálise e internação prolongada). RESULTADOS: A incidência de IRA variou de 15% - 51%, conforme o critério diagnóstico adotado. Enquanto a idade se associou ao risco de IRA nos três critérios, houve variação nos demais determinantes. Durante o acompanhamento, 89 pacientes apresentaram o desfecho e todos os critérios se associaram ao risco aumentado na análise Cox univariada e após o ajuste para idade, sexo, diabetes e tipo de cirurgia. Contudo, após novo ajuste para tempo de circulação extracorpórea e presença de baixo débito cardíaco, apenas o diagnóstico de IRA pelo critério KDIGO manteve esta associação significativa (HR= 1,89 [95% IC: 1,18 - 3,06]). CONCLUSÕES: A incidência e os fatores de risco para IRA pós-cirurgia cardíaca têm grande variação de acordo com os critérios diagnósticos utilizados. Em nossa análise, o critério KDIGO se mostrou superior ao AKIN e ao RIFLE quanto ao seu poder prognóstico.

BACKGROUND: There is considerable controversy regarding the diagnosis of Acute Kidney Injury (AKI), and there are over 30 different definitions. OBJECTIVE: To evaluate the incidence and risk factors for the development of AKI following cardiac surgery according to the RIFLE, AKIN and KDIGO criteria, and compare the prognostic power of these criteria. METHODS: Cross-sectional study that included 321 consecutively patients (median age 62 [53-71] years; 140 men) undergoing cardiac surgery between June 2011 and January 2012. The patients were followed for up to 30 days, for a composite outcome (mortality, need for dialysis and extended hospitalization). RESULTS: The incidence of AKI ranged from 15% - 51%, accordingly to the diagnostic criterion adopted. While age was associated with risk of AKI in the three criteria, there were variations in the remaining risk factors. During follow-up, 89 patients developed the outcome and all criteria were associated with increased risk in the univariate Cox analysis and after adjustment for age, gender, diabetes, and type of surgery. However, after further adjustment for extracorporeal circulation and the presence of low cardiac output, only AKI diagnosed by the KDIGO criterion maintained this significant association (HR= 1.89 [95% CI: 1.18 - 3.06]). CONCLUSION: The incidence and risk factors for AKI after cardiac surgery vary significantly according to the diagnostic criteria used. In our analysis, AKI the KDIGO criterion was superior to AKIN and RIFLE with regard its prognostic power.
