Abstract

INTRODUCTION: Catheter-associated bloodstream infection (CA-BSI) is the most common nosocomial infection in neonatal intensive care units. There is evidence that care bundles to reduce CA-BSI are effective in the adult literature. The aim of this study was to reduce CA-BSI in a Brazilian neonatal intensive care unit by means of a care bundle including few strategies or procedures of prevention and control of these infections. METHODS: An intervention designed to reduce CA-BSI with five evidence-based procedures was conducted. RESULTS: A total of sixty-seven (26.7%) CA-BSIs were observed. There were 46 (32%) episodes of culture-proven sepsis in group preintervention (24.1 per 1,000 catheter days [CVC days]). Neonates in the group after implementation of the intervention had 21 (19.6%) episodes of CA-BSI (14.9 per 1,000 CVC days). The incidence of CA-BSI decreased significantly after the intervention from the group preintervention and postintervention (32% to 19.6%, 24.1 per 1,000 CVC days to 14.9 per 1,000 CVC days, p=0.04). In the multiple logistic regression analysis, the use of more than 3 antibiotics and length of stay >8 days were independent risk factors for BSI. CONCLUSIONS: A stepwise introduction of evidence-based intervention and intensive and continuous education of all healthcare workers are effective in reducing CA-BSI.INTRODUÇÃO: As infecções de corrente sanguínea associadas ao cateter (ICS-AC) são as infecções hospitalares mais frequentes em unidades de terapia intensiva neonatais. O objetivo do nosso estudo foi reduzir as ICS-AC através de um pacote de medidas de cuidados incluindo algumas estratégias de controle e prevenção destas infecções. MÉTODOS: Foi realizada uma intervenção desenhada para reduzir as infecções de corrente sanguínea associadas ao cateter com cinco procedimentos de base. RESULTADOS: Um total de 67 (26,7%) ICS-AC foi observado. Houve 46 (32%) episódios de sepse com critério microbiológico (24,1 por 1.000 catater dias(CVC-dias). Os neonatos do grupo, após a implementação da intervenção, tiveram 21 (19,6%) episódios de ICS-AC (14,9 por 1.000 CVC-dias). A incidência de ICS-AC reduziu significantemente entre os grupos pré-intervenção e pós-intervenção após a implementação das medidas (32% para 19.6%, 24.1 por 1.000 CVC-dias para 14.9 por 1.000 CVC-dias, p=0.04). Na análise de regressão logística múltipla, o uso de > três antibióticos e tempo de hospitalização > 8 dias foram fatores de risco independentes para ICS. CONCLUSÕES: A introdução de uma intervenção baseada em evidências e a educação intensiva e continuada de todos os profissionais de saúde são efetivas para a redução de ICS-AC.
