Risk factors and drug resistance of adult community-onset urinary tract infections caused by

To evaluate the prevalence, resistance and risk factors of community-onset urinary tract infections (COUTIs) caused by extended-spectrum β-lactamase-producing A retrospective case-control study. The Affiliated Dazu Hospital of Chongqing Medical University (also known as The People's Hospital of Dazu Chongqing), a 1000-bed tertiary hospital in China. This study encompassed adult patients diagnosed with community-acquired urinary tract infections (UTIs) caused by The risk factors for COUTIs caused by ESBL-EC were evaluated using a case-control design, defining patients who were diagnosed with UTIs and had an ESBL-positive urine culture as the case group and patients who were diagnosed with UTIs and had an ESBL-negative urine culture as the control group. Perform drug susceptibility testing and resistance analysis on isolated ESBL-EC. In total, 394 cases of COUTIs caused by Our results revealed high ESBL-EC detection rates. COUTIs caused by ESBL-EC are more likely to occur in patients with parenchymal tumour, a history of urolithiasis stone fragmentation, a history of urological surgery, hospitalisation within 6 months, indwelling catheter outside the hospital and use of third-generation cephalosporins. These patients were highly resistant to penicillins, cephalosporins and quinolones.
