Eventos gerenciais e assistenciais como interferências na carga de trabalho / Managerial and assistance events such as workload interference / Eventos gerenciales y de asistencia como interferencia en la carga de trabajo

Objetivo: Analisar eventos no processo de trabalho gerencial e assistencial da enfermagem, como interferências na carga de trabalho de enfermagem em Unidade de Terapia Intensiva. Métodos: Estudo epidemiológico, transversal, de série histórica na análise da carga de trabalho. Foram realizadas aferições do Nursing Activities Score entre 2007 a 2014. Os eventos foram divididos em ações gerenciais e assistenciais. Resultados: O Nursing Activities Score foi aplicado 35262 vezes em 4731 pacientes. Entre as intervenções gerenciais, a carga de trabalho foi maior na vigência da Resolução da Diretoria Colegiada nº. 26 da Agência Nacional de Vigilância Sanitária concomitante ao aumento da proporção de pacientes por enfermeiro (p<0,001), na implantação dos sítios assistenciais (p<0,001) e na expansão da unidade (p<0,001). Entre as intervenções assistenciais, houve aumento da carga de trabalho no período de incorporação tecnológica (p<0,001), credenciamento de transplante hepático (p<0,001) e implantação de bundle de controle de infecção (p<0,001). Conclusão: Os eventos no processo de trabalho gerencial e assistencial da enfermagem que tiveram como objetivo melhorar a qualidade da assistência, constituem fatores que interferem na carga de trabalho da enfermagem em UTI, uma vez que esta tem aumentado ao longo dos anos.

Objective: To analyze events in the managerial and care work process, such as interferences in the nursing workload in the Intensive Care Unit. Methods: Epidemiological, cross-sectional, historical series study on workload analysis. Measurements of the Nursing Activities Score were carried out between 2007 and 2014. The events were divided into managerial and assistance actions. Results: The Nursing Activities Score was applied 35262 times to 4731 patients. Among management interventions, the workload was greater under the Directors' Collegiate Resolution no. 26 of the National Health Surveillance Agency concomitant to the increase in the proportion of patients per nurse (p<0.001), in the implantation of assistance sites (p<0.001) and in the expansion of the unit (p<0.001). Among assistance interventions, there was an increase in the workload in the period of technological incorporation (p<0.001), accreditation of liver transplantation (p<0.001) and implantation of an infection control bundle (p<0.001). Conclusion: Interventions that aimed to improve the quality of care are factors that interfere with the nursing workload in the ICU, whereas it has increased over the years. (AU)

Objetivo: Analizar eventos en el proceso de trabajo gerencial y asistencial, como interferencias en la carga de trabajo de enfermería en la Unidad de Cuidados Intensivos. Métodos: Estudio epidemiológico, transversal, de serie histórica sobre análisis de carga de trabajo. Las mediciones del Puntaje de Actividades de Enfermería se realizaron entre 2007 y 2014. Los eventos se dividieron en acciones gerenciales y asistenciales. Resultados: El puntaje de actividades de enfermería se aplicó 35262 veces a 4731 pacientes. Entre las intervenciones de gestión, la carga de trabajo fue mayor bajo la Resolución del Consejo Colegiado no. 26 de la Agencia Nacional de Vigilancia Sanitaria concomitante al aumento de la proporción de pacientes por enfermera (p <0,001), en la implantación de sitios asistenciales (p <0,001) y en la ampliación de la unidad (p <0,001). Entre las intervenciones asistenciales, hubo un aumento de la carga de trabajo en el período de incorporación tecnológica (p <0,001), acreditación de trasplante hepático (p <0,001) e implantación de un paquete de control de infecciones (p <0,001). Conclusion: Las intervenciones dirigidas a mejorar la calidad de la atención son factores que interfieren con la carga de trabajo de enfermería en la UCI, mientras que se ha incrementado con los años.

Molecular epidemiology of methicillin-resistant Staphylococcus aureus in the Brazilian primary health care system.

OBJECTIVE: To evaluate the molecular epidemiology and to georeference Staphylococcus aureus isolated from wounds and nares of patients seen at Basic Health Units (BHUs) of a Brazilian city. METHODS: Observational, cross-sectional study conducted from 2010 to 2013. A total of 119 S. aureus strains isolated from the wounds and nares of 88 patients were studied. The isolates were characterised by identifying virulence genes encoding enterotoxins A-E, haemolysins α, ß and δ, exfoliatins A, B and D, biofilm production, Panton-Valentine Leukocidin and toxic shock syndrome toxin 1, and by pulsed-field gel electrophoresis (PFGE), multilocus sequence and spa typing. RESULTS: Eighteen methicillin-resistant Staphylococcus aureus (MRSA) (6 SCCmec type II and 12 SCCmec type IV) and 101 (85%) MSSA were identified. PFGE typing resulted in the formation of eight clusters, with STs 1, 5, 8, 30, 188, 1176 and 1635 and spa type t002 being the predominant types among MSSA. The 18 MRSA belonged to STs 5, 8 and 1176 and spa types t002 and t062. CONCLUSION: The results demonstrate widespread dissemination of MSSA and MRSA clones carrying haemolysin, biofilm and toxin genes. Kernel density estimation revealed the highest density of S. aureus in the 4, 5 and 8 BHUs.

OBJECTIF: Evaluer l'épidémiologie moléculaire et géoréférencer le Staphylococcus aureus isolé de plaies et de narines de patients vus dans les unités sanitaires de base (BHU) d'une ville brésilienne. MÉTHODES: Etude observationnelle transversale réalisée de 2010 à 2013. Au total, 119 souches de S. aureus isolées de plaies et de narines de 88 patients ont été étudiées. Les isolats ont été caractérisés par l'identification de gènes de virulence codant pour les entérotoxines AE, les hémolysines α, ß et δ, les exfoliatines A, B et D, la production de biofilm, la leucocidine de Panton-Valentine et la toxine 1 du syndrome de choc toxique, et par typage par électrophorèse sur gel en champ pulsé (PFGE), séquence multilocus et spa. RÉSULTATS: Dix-huit SARM (6 de type II SCCmec et 12 de type IV SCCmec) et 101 (85%) SASM ont été identifiés. Le typage PFGE a résulté à l'obtention de huit grappes, dont STs 1, 5, 8, 30, 188, 1176 et 1635 et le type spa t002 étant les types prédominants parmi les SASM. Les 18 SARM appartenaient aux STs 5, 8 et 1176 et aux types de spa t002 et t062. CONCLUSION: Les résultats démontrent une dissémination étendue des clones de SASM et de SARM portant les gènes de l'hémolysine, de biofilm et de toxine. L'estimation de la densité par noyau a révélé la densité la plus élevée de S. aureus dans les 4, 5 et 8 BHU.

Prevalence of and risk factors associated with the presence of Staphylococcus aureus in the chronic wounds of patients treated in primary health care settings in Brazil

Abstract INTRODUCTION: Wounds can be colonized by methicillin-resistant Staphylococcus aureus (MRSA). METHODS: We evaluated the prevalence of S. aureus and MRSA in the wounds of patients treated at Basic Health Units in Brazil and identified risk factors associated with their presence. RESULTS: The prevalence rates of S. aureus and MRSA were 51.5% and 8.7%, respectively. There was a correlation between the presence of S. aureus in wounds and nostrils (p<0.01). A positive association was detected between S. aureus infection and previous benzylpenicillin use (p=0.02). No associations were observed for MRSA. CONCLUSIONS: Multidrug-resistant pathogens are present in primary healthcare settings in Brazil.
