| Summary: | Introduction: Urinary Tract Infections (UTI) are an important cause of morbidity in the community, constituting one of the main reasons for hospitalization, and the fourth cause of healthcare-associated infection. The objectives of this study were to determine the frequency of community-acquired UTI (CA-UTI) with need of hospitalization and healthcare-associated UTI (HA-UTI), their risk factors, etiologic agents and their antimicrobial susceptibility spectrum.
Methods: A prospective and analytic study was conducted, in which all admissions regarding CA-UTI with need of hospitalization and HA-UTI were evaluated during the period between 2016 and 2017 in two university hospitals.
Results: A total of 279 episodes of UTI in hospitalized patients were identified and, among those, 178 episodes corresponded to CA-UTI and 101 to HA-UTI. On average, patients were 60 years old in both groups. HA-UTI were more frequently associated with kidney transplant, recurrent UTI and chronic kidney disease compared with CA-UTI. The instrumentation of urinary tract within the previous month was more frequent in HA-UTI (75.2% vs 32.6%, p<0.001). Escherichia coli was the most frequent isolated microorganism (62.9% in CA-UTI and 56.4% in HA-UTI), followed by Klebsiella pneumoniae and Pseudomonas aeruginosa. A total of 101 multidrug resistant microorganisms were isolated, of which 53.5% were CA-UTI, and were associated with male patients, use of antimicrobials within the previous three months, chronic kidney disease and recurrent UTI.
Main conclusion: It is of great importance for the institutions to identify the local antimicrobial susceptibility spectrum of UTI in order to stablish adequate empiric treatments. |
