Introduction:

urine culture is the primary tool for diagnosing urinary tract infections, but positive results vary widely.

Objective:

to describe urine culture results in outpatients attending the laboratory of the Centro Médico Nacional-Hospital Nacional during the 2022-2023 period.

Methodology:

this was an observational, descriptive, cross-sectional study with an analytical component. Patients over 15 years of age who attended the Laboratory Service of the Centro Médico Nacional-Hospital Nacional with a urine culture request and who agreed to participate in the study were included.

Results:

a total of 900 patients were included, aged 38.9±17.0 years (range 15-91 years), 756 (84 %) were female, of whom 337 (44.9 %) were pregnant. Of the total patients, 98 (10.9 %) had positive urine cultures, with Escherichia coli being the most common microorganism isolated in 74 (75.5 %) and Klebsiella pneumoniae in 9 (9.2 %). Multivariate analysis found significant differences in positive results based on sex (Wald 2.306; p = 0.021), history of urinary tract infection (W 2.891; p = 0.004), and history of urinary catheter use (W 2.676; p = 0.007).

Conclusion:

the frequency of positive urine cultures in the outpatient population of the Centro Médico Nacional-Hospital Nacional was 10.9 %, with Escherichia coli and Klebsiella pneumoniae being the most common microorganisms.
