ABSTRACT

OBJECTIVE:

Although urinary tract infections (UTIs) are the most common hospital-acquired infections, the epidemiology of these UTIs is not well defined in Turkey. The aim of this surveillance study was to determine micro-organisms responsible for UTI, their antibiotic sensitivities and to describe the incidence and risk factors of nosocomial urinary tract infections (NUTI). SUBJECTS AND

METHODS:

This was a prospective surveillance study including cases of NUTI in intensive care units and various inpatient clinics. This study was carried out between November 2000 and January 2002. The following information was recorded patients' age, gender, type of infection (hospital-acquired), presence of urinary catheter, intensive care unit admission, duration of hospital stay, type of organisms isolated and their antimicrobial susceptibility. The diagnosis of NUTI was based on criteria established by the Centers for Disease Control, Atlanta. Mini Api and conventional culture methods were used to determine the causative agents. The agents were isolated on eosin methylene blue agar and 5sheep blood agar Statistical analyses of data were by chi-square test and logistic regression.

RESULTS:

In this study, 618 (2.1) nosocomial infections (NIs) were determined in 29,778 patients, and 178 of these infections were NUTI (28.8, 178/618). The mean age of NUTI patients was 61.0 +/- 19.4 years (0-91 years) and 82 NUTI patients (46.1) were male and 96 (53.9) were female. The most frequently isolated micro-organism was Escherichia coli (31.4) followed by Candida spp (21.3), Klebsiella spp (10.6) and Enterococcus spp (6.9). Compared to the rate of other NIs, the rate of NUTI increased by 1.011 times per year of age, by 2.052 times in females and by 3.83 times in patients with urinary catheters (p < 0.05). The most effective antibiotics against Gram-negative bacteria were found to be imipenem and meropenem.

CONCLUSIONS:

Important factors to prevent NUTI are to avoid unneces...
RESUMEN

OBJETIVO:

Aunque las infecciones del tracto urinario (ITU) son las que con mayor frecuencia se adquieren en los hospitales, su epidemiología no se halla bien definida en Turquía. El objetivo de este estudio de vigilancia fue determinar los microorganismos responsables de la ITU, sus sensibilidades antibióticas, y describir la incidencia y los factores de riesgo de las infecciones del tracto urinario nosocomiales (ITUN). SUJEITOS Y

MÉTODOS:

Este fue un estudio prospectivo de vigilancia que incluyó casos de ITUN en unidades de cuidados intensivos y en varias clínicas de ingreso. El estudio se llevó a cabo entre noviembre de 2000 y enero de 2002. Se registró la siguiente información edad del paciente, sexo, tipo de infección (adquirida en el hospital), presencia de catéter urinario, ingreso a la unidad de cuidados intensivos, duración de la estadía hospitalaria, y el tipo de organismo aislado así como su susceptibilidad antimicrobiana. El diagnóstico de ITUN se basó en criterios establecidos por los Centros de Control de Enfermedades, Atlanta. El sistema Mini Api y métodos de cultivo convencionales fueron usados con el propósito de determinar los agentes causantes. Los agentes causantes fueron aislados sobre agar-eosina-azul de metileno y agar sangre de oveja a 5%. El análisis estadístico de los datos se realizó usando la prueba de chi-cuadrado y regresión logística.

RESULTS:

En este estudio, se determinaron 618 (2.1%) infecciones nosocomiales (IN) en 29 778 pacien-tes, y 178 de estas infecciones resultaron ser INTU (28.8%, 178/618). La edad media de los pacientes de INTU fue 61.0 B1 19.4 años (0–91 años) y 82 pacientes de INTU (46.1%) fueron varones y 96 (53.9%) fueron hembras. El micro-organismo más frecuentemente aislado fue Escherichia coli (31.4%), seguido por Candida spp (21.3%), Klebsiella spp (10.6%) y Enterococcus spp (6.9%). En comparación con la tasa de otras IN, la tasa de INTU aumentó 1.011 veces por año de edad, 2.052 veces en las...
