Background: antibiotic resistance is a major problem, being carbapenem-resistant microorganisms the paradigm of multiresistance. Urinary tract is the most frequent site of infection, being the decision of treating its isolation an added difficulty due to the patient’s profile. Methods: descriptive transversal unicentric and retrospective study involving 106 patients with carbapenem-resistant microorganism in an urine culture. Epidemiological, clinical, microbiological characteristics and antibiotic treatment descriptive variables were gathered, and a rating scale was used to score the treatment based on the “Medication Appropiateness Index”. Results: considering the inclusion terms, 106 of the total 175 cultures reviewed were taken, with a male percentage of 62.3% with an average age of 70.6 years old, mainly from home and 4.9 points in Charlson's index. The isolation of the microorganism was nosocomial origin up to 32.45%, 65.1% corresponded to K. pneumoniae and producing strains of OXA-48. It was applied treatment in 72 patients, 60 of which were monotherapy, being carbapenems the widest drug used. From the total sample, 9 patients died, only 3 of them caused by urinary infection. No statistically significant differences were found among the patients who received antibiotic treatment classified as inadequate versus adequate, except for age, being the considerably younger (p=0.019) those who received an adequated qualification. Globally, only 33% got an adequate qualification in the treatment. From this comparative, no differences were found among the infection characteristics nor were they on the election of monotherapy versus bi-therapy. When looking at the scale design criteria there were no differences among the patients who died and those who did not. Conclusions: being a comparable population with other studies and dealing exclusively with tract urinary infections, it could be that despite an overall unfavorable treatment, this did not influence both the evolution of the patients and other more severe infections.
