Infeccion urinaria relacionada con sonda uretral en pacientes críticos ingresados en UCI Datos descriptivos del estudio ENVIN-UCI


, : Infeccion urinaria relacionada con sonda uretral en pacientes críticos ingresados en UCI Datos descriptivos del estudio ENVIN-UCI.

Describir la evoluci n de las tasas nacionales de las infecciones urinarias relacionada con sonda uretral (IU-SU), as como la de sus etiolog as y marcadores de multirresistencia. Estudio observacional, prospectivo, de participaci n voluntaria y multic ntrico desde el 1 de abril al 30 de junio entre los a os 2005 y 2010. Unidades de Cuidados Intensivos (UCI) que participaron en el registro ENVIN-UCI en el periodo de estudio. Se han incluido todos los pacientes ingresados en las UCI participantes y portadores de sonda urinaria durante m s de 24 horas (78.863 pacientes) La vigilancia de los pacientes ha sido continua hasta el alta de UCI o un m ximo de 60 d as. Se han definido las IU-SU siguiendo los criterios del CDC y su frecuencia se expresa como densidad de incidencia (DI) en relaci n al n mero de d as de paciente-SU. Han presentado una o m s IU-SU 2.329 (2,95%) pacientes. La DI de IU-SU ha disminuido desde 6,69 a 4,18 episodios por 1.000 d as de SU desde el a o 2005 al a o 2010 (p<0,001). En la etiolog a han predominado los bacilos gramnegativos (55,6-61,6%), seguido de hongos (18,7-25,2) y de los cocos grampositivos (17,1-25,9%). En el a o 2010, han aumentado las cepas de E. coli resistentes a ciprofloxacino (37,1%) y de P. aeruginosa resistente a imipenem (36,4%) y ciprofloxacino (37,1%). Disminuci n de las tasas de IU-SU, manteni ndose la misma distribuci n de etiolog a e increment ndose las resistencia en los BGN, en especial el E. coli y P. aeruginosa. To describe trends in national catheter-related urinary tract infection (CRUTI) rates, as well as etiologies and multiresistance markers. An observational, prospective, multicenter voluntary participation study was conducted from 1 April to 30 June in the period between 2005 and 2010. Intensive Care Units (ICUs) that participated in the ENVIN-ICU registry during the study period. We included all patients admitted to the participating ICUs and patients with urinary catheter placement for more than 24hours (78,863 patients). Patient monitoring was continued until discharge from the ICU or up to 60 days. CRUTIs were defined according to the CDC system, and frequency is expressed as incidence density (ID) in relation to the number of urinary catheter-patients days. A total of 2329 patients (2.95%) developed one or more CRUTI. The ID decreased from 6.69 to 4.18 episodes per 1000 days of urinary catheter between 2005 and 2010 (p<0.001). In relation to the underlying etiology, gramnegative bacilli predominated (55.6 to 61.6%), followed by fungi (18.7 to 25.2%) and grampositive cocci (17.1 to 25.9%). In 2010, ciprofloxacin-resistant E. coli strains (37.1%) increased, as well as imipenem-resistant (36.4%) and ciprofloxacin-resistant (37.1%) strains of P. aeruginosa. A decrease was observed in CRUTI rates, maintaining the same etiological distribution and showing increased resistances in gramnegative pathogens, especially E. coli and P. aeruginosa..
