Abstract

PINEDA-POSADA, Mariana et al. Risk factors for the development of community-acquired urinary tract infection, by extended-spectrum beta-lactamase producing microorganisms, at two hospitals in Bogotá, Colombia. Infect. [online]. 2017, vol.21, n.3, pp.141-147. ISSN 0123-9392.  https://doi.org/10.22354/in.v21i3.670.

Aims:

To determine risk factors for the development of community-acquired urinary tract infection, by extended-spectrum beta-lactamase producing microorganisms, in adult patients.

Materials and methods:

A case-control study in the period from January 2012 to May 2015, in two hospitals in Bogota, Colombia. Matching for age, year of isolation, microorganism and gender. We excluded patients with a history of infection with extended-spectrum beta-lactamase producing microorganisms in the last month and urinary infection associated with health care.

Results:

555 patients were analyzed.185 cases and 370 controls. 462 patients (83.2%) from Fundación Clínica Shaio and 93 (16.8%) from Hospital Santa Clara. Identified risk factors: recurrent urinary tract infection (OR= 2.13, 95% CI= 1.48 - 3.07), chronic kidney disease (OR= 1.56, 95% CI= 1.07 - 2.27), previous use of antibiotics (OR= 3.46, 95% CI= 2.48 - 5.35), recent hospitalization (OR= 3.0, 95% CI= 1.96 to 2.45), diabetes mellitus (OR= 1.61, 95% CI= 1.06 - 2.45) and upper urinary tract infection (OR= 2.64, 95% CI= 1.61 - 4.32).

Conclusions:

The risk factors community-acquired urinary tract infection, by extended-spectrum beta-lactamase producing microorganisms, were in order of frequency: history of recent antibiotic therapy, prior hospitalization, the presence of high urinary infection, history of recurrent urinary tract infection, chronic kidney disease and diabetes mellitus. The described risk factors are consistent with the main findings described in the literature.
