Infecciones de vías urinarias en el Hospital Universidad del Norte / Urinary tract infections in the Hospital Universidad del Norte

ABSTRACT

Objective: Determine the epidemiological behavior of the Urinary Tract Infections and thechanges in sensibility and antibiotic resistance of Escherichia coli in the Hospital Universidaddel Norte, Soledad, Atlántico. January 2005 to december 2006.Materials and methods: There was realized a descriptive study of retrospective type,with a sample of 537 cultures of the patients who consult at Hospital Universidad delNorte. The cultures were evaluated across the colonies forming units (CFU) and then theantibiograms’ reports were analyzed, annotating the information for resistance, antibioticsensibility and evaluating the epidemiological behavior of the principal antibiotics used inthe clinical practice at this institution.Results: The percentage distribution of Urinary Tract Infection f (UTI) found in 2005in women 72.9 percent, men 27.1 percent, and in 2006, women 73.8 percent, men 26.2 percent. The mostfrecuent microorganisms in 2005 were Escherichia coli (66.24 percent), Klebsiella (10.63 percent) andfor 2006 Escherichia coli (85 percent), Proteus (5.29 percent). The major rates of antibiotic resistanceof the Escherichia coli in 2005 was ampicilina, trimetoprim sulfa and ciprofloxacina. In2006 the behavior was similar, but decrease is observed in the resistance to fluoroquinolonas;the major rates of sensibility in 2005 include nitrofurantoína, ampicilina/sulbactam andaminoglucosidos in relation to 2006, in which decrease is observed in the sensibility to thefirst and the second one.Conclusion: The percentage distribution shows that UTI is more frequent in women. Thecausal microorganism of most of UTI’s cases is Escherichia coli. Decrease was demonstrated inthe rates of resistance to ampicilina, trimetoprim sulfametaxol, first generation cefalosporinesand ciprofloxacina in 2006 with relation to 2005.
