Bacteriological study of Hospital-acquired urinary tract infections in Erbil city

Abstract

Background and objectives: Urinary tract infections are amongst the most common infections, Hospital-acquired urinary tract infection increases not only morbidity and mortality but also hospital costs. The objectives of this study were to determine bacteria responsible for hospital-acquired urinary tract infection, their antibiotic sensitivities and to describe the risk factors of the infection.Methods: All urine samples fulfilling the criteria for significant bacteriuria were included in the study. Isolation and identification of bacteria was performed by standard method and susceptibility testing was determined by disk diffusion method.Results: Out of 290 patients, 133 (45.86%) have acquired hospital-acquired urinary tract infection. Older age, hospitalization and catheterization were risk factors of the infection. Escherichia coli (51.70%) and Klebsiella pneumoniae (16.33%) represented the most common isolates. The most bacteria isolates were sensitive to ciprofloxacin, rifampin and trimethoprim + sulphamethoxazole.Conclusions: To prevent hospital-acquired urinary tract infections, important factors must be taken into consideration, for example: avoid unnecessary urethral catheterization, choose narrow spectrum antibiotics according to antibiotic sensitivities, and investigate regularly the causative bacteria and their susceptibility patterns
