Abstract (English): |
Introduction. Multidrug resistant (MDR) microorganisms represent a threat for patients admitted in Intensive Care Units (ICUs). The objective of the present study is to analyse the results of epidemiological surveillance cultures for these microorganisms in one of these units. Material and methods. General ICU. Retrospective analysis, descriptive statistics. Analysis of epidemiological surveillance cultures for MDR microorganisms in 2015. Studied microorganisms: Methicillin-resistant Staphylococcus aureus (MRSA), ESBL-and/or carbapenemase-producing Klebsiella pneumoniae (CESBL-KP) and MDR Acinetobacter baumannii (MDRAB). Results. One thousand, two hundred and fifty nine patients admitted. A total of 2,234 specimens from 384 patients were analysed (690, 634, 62 and 286 were rectal, throat, nasal and skin swabs respectively). Global APACHE II was 18.3 ± 8 versus 21.7 ± 7.8 in patients colonized/infected on admission. Global mortality was 19.7% versus 22.3% in patients colonized/infected on admission. The higher sensitivities achieved with the different samples for the different microorganism detection were as follows. MRSA: 79% and 90% for nasal and nasal + throat swabs, respectively. MDRAB: 80% and 95% for throat and throat + rectal swabs, respectively. CESBL-KP: 95% and 98% for rectal and rectal + throat swabs, respectively. 94 out of the 384 patients (24.4%) were colonized/infected with MDR at admission. 134 patients (10.6% of the total patients admitted) were colonized/infected with a total of 169 MMR during the hospital stay. MRSA has the earliest colonization/infection (9.2 ± 6.4days) and ESBL-producing Enterobacteriaceae, the latest (18.7± 16.4 days). Conclusions. 24.4% of patients were colonized/infected by MDR at admission. Nasal, throat and rectal swabs were the most effective specimens for recovering MRSA, MDRAB and CESBL-KP, respectively. The combination of two specimens improves MDR detection except for CESBL-KP. Skin swabs are worthless. The most prevalent MDR at admission were ESBL-producing Enterobacteriaceae while the most frequent hospital acquired MDR was MDRAB. [ABSTRACT FROM AUTHOR] |

Introducción. Los microorganismos multirresistentes (MMR) suponen una amenaza para los pacientes ingresados en las Unidades de Cuidados Intensivos (UCIs). El objetivo de este estudio es analizar los resultados de los cultivos de vigilancia epidemiológica de dichos microorganismos en una de estas unidades. Material y métodos. UCI polivalente. Análisis retrospectivo, estadística descriptiva. Análisis de cultivos de vigilancia epidemiológica para MMR. Microorganismos estudiados: Staphylococcus aureus resistente a meticilina (SARM), Klebsiella pneumoniae productora de BLEE y/o carbapenemasa (KPBLEEC) y Acinetobacter baumannii multirresistente (ABMR). Resultados. 1.259 pacientes ingresados. Se analizaron 2.234 muestras (exudado rectal 690, faríngeo 634, nasal 624, cutáneo 286) procedentes de 384 pacientes. La mayor rentabilidad alcanzada con las diferentes muestras para los distintos microorganismos fue: SARM, exudado nasal 79%, nasal + faríngeo 90%. ABMR: faríngeo 80%, faríngeo + rectal 95%. KPBLEE-C: rectal 95%, faríngeo + rectal 98%. De los 384 pacientes 94 (24,4%) estaban colonizados/infectados al ingreso con alguno de estos microorganismos. Durante su estancia, 134 pacientes (10,6% del total de pacientes ingresados) se colonizaron/infectaron por un total de 169 microorganismos. La colonización/infección más precoz fue para SARM (9,2 ± 6,4 días) y la más tardía para enterobacterias productoras de BLEE (18,7±16,4 días). Conclusiones. El 24,4% de los pacientes estaban colonizados/infectados por MMR al ingreso. Las muestras más rentables fueron exudado nasal para SARM, faríngeo para ABMR y rectal para KPBLEE-C. La asociación de dos muestras mejora la detección, excepto en KPBLEE-C. Los exudados cutáneos son poco rentables. El MMR más frecuente al ingreso son las enterobacterias productoras de BLEE y el adquirido intra UCI el ABMR. [ABSTRACT FROM AUTHOR] |
