Effectiveness of oral antibiotics in managing extended-spectrum B-lactamase urinary tract infections: A retrospective analysis
Abstract
Background: Urinary tract infections caused by extended-spectrum beta-lactamase organisms pose a significant concern worldwide. Given the escalating prevalence of drug resistance and the limited data on the effectiveness of oral antibiotics in treating these infections, this study aimed to assess the clinical outcomes in adult patients with extended-spectrum beta-lactamase urinary tract infections treated with oral antibiotics. Methods: A retrospective observational cohort study was conducted at King Abdulaziz Medical City, Saudi Arabia, from January 2018 to December 2021. It included patients ⩾18 years with complicated or uncomplicated urinary tract infections from extended-spectrum beta-lactamase Enterobacterales and treated with oral antibiotics as step-down or mainstay therapy. All-cause clinical failure within 30 days post-discharge was evaluated as the efficacy outcome. Statistical analyses were performed using SPSS software. Results: Out of 643 screened patients, 152 patients met the inclusion criteria. The patients were divided into oral step-down therapy (51.3%) and oral-only (48.7%) groups. The majority (69.1%) were females, with a mean age of 62 years. Complicated urinary tract infections were diagnosed in (75.5%) of cases, and the predominant pathogen was E. coli (79.6%). Clinical failure was observed in 23.1% in the oral step-down group and 13.5% in the oral-only group, with no significant difference ( p = 0.128). Total antibiotics duration was significantly…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 643 participants or records.
