Antibiotic Resistance Pattern of Urinary Tract Infections Among Patients with Recent Antibiotic Use: A Cross-sectional Study

 With the increasing rate of bacterial resistance and the emergence of multidrug-resistant pathogens, urinary tract infections (UTIs) are now among the most important public health problems worldwide.

 This study aimed to investigate the antibiotic resistance patterns of UTIs in Shahid Rahimi and Shohada-ye Ashayer hospitals of Khorramabad, Iran, in 2021.

 In this cross-sectional study, 250 patients with UTI were included. Demographic characteristics and data related to the pathogen types and antibiogram were collected from their medical files and recorded in a researcher-made checklist. The collected data were analyzed by Stata software version 14 at a 5% significance level.

 The study population consisted of 163 women (65.2%) with a mean age of 54.52 ± 10.12 and 87 men (34.8%) with a mean age of 51.87 ± 12.01. The most common pathogens reported were Escherichia coli (41.20%), followed by Staphylococcus saprophyticus (20.80%), and Klebsiella pneumonia (18.40%). The most frequently reported resistances were against Amoxicillin (59.2%), followed by Ampicillin (53.6%), while the least reported were Imipenem (11.6%), followed by Amikacin (17.6%).

 A high rate of resistance was observed against the commonly used antibiotics. It is crucial to prescribe antibiotics, particularly those with relatively low resistance rates (such as imipenem and amikacin), cautiously to prevent bacterial resistance against antimicrobial agents.
