ABSTRACT
INTRODUCCIÓN: Stenotrophomonas maltophilia origina raramente brotes nosocomiales. MÉTODOS: Descripción de un brote y la intervención realizada. Se comparó la incidencia acumulada (IA) en el periodo epidémico (PE) y preepidémico (PPE). Se realizaron cultivos ambientales. RESULTADOS: Ocurrieron 5 casos durante el PE con una IA de 3% (IC 95% 0,4-6), 4,8 veces superior a la del PPE. S. maltophilia creció en 6 grifos y el brote se controló tras su retirada. CONCLUSIÓN: desde el punto de vista de la prevención, es importante controlar determinados reservorios para evitar brotes nosocomiales
INTRODUCTION: Stenotrophomonas maltophilia is an infrequent cause of nosocomial outbreaks. METHODS: Outbreak report and intervention study. The accumulated incidence (AI) of the epidemic period (EP) was compared with AI of the pre-epidemic period (PEP). RESULTS: During EP, five cases were identified. AI was 3% (IC 95% 0,4-6), 4,8 times higher than the AI of PEP. S. maltophilia was isolated from the tap water faucets. The outbreak was controlled after removing the faucets. CONCLUSION: It is important to control environmental reservoirs to prevent outbreaks
