Nosocomial infections (NI) represent a major problem of public health not only due to its high frequency, but to its consequences reflected in terms of morbidity, mortality, length of hospital stay and healthcare costs, variables used as indicators of health services quality. Objective: To determine the frequency of nosocomial urinary tract infection (NUTI) at the medicine services at a general hospital, the most frequent microorganism isolated, its antibiotic sensibility, related factors, and the patient’s demographic characteristics. Material and Methods: A cross sectional study was conducted on 48 hours at the Hospital Nacional Cayetano Heredia. Were selected all the patients with symptomatic NUTI and asymptomatic bacteriuria according to the standard definition of the Centers for Diseases Control and Prevention (CDC). Results: Including patients with symptomatic NUTI and asymptomatic bacteriuria the prevalence rate was 12%. Tuberculosis and nephro-urologic disease were releated in independent form to NUTI presence. The most frequent microorganism isolated was E. coli followed by Klebsiella pneumoniae. Of the E.coli isolated, were resistant to ciprofloxacin 5/5, ceftriaxone 3/5, amikacin and gentamicin 1/5. Conclusions: Our NUTI frequency was 12%. The stocks of E. coli isolated showed high resistance to first-line antibiotics like ciprofloxacin and ceftriaxone, but high sensibility to aminoglicosides.
