This retrospective cohort study in a tertiary hospital in southern China found that inappropriate empirical antibiotic treatment for urinary tract infections caused by E. coli was associated with longer hospital length of stay. Empirical use of fluoroquinolones for UTIs should be avoided to reduce healthcare costs and bacterial resistance.
Objectives: We aimed to determine the clinical impact of inappropriate empirical antibiotic treatment (IEAT) compared with appropriate empirical antibiotic treatment (AEAT) in hospitalised patients with urinary tract infections (UTIs) caused by Escherichia coli (E. coli). Methods: This retrospective cohort study included adult patients with a primary diagnosis of UTI who were treated with empirical antibiotics at a tertiary hospital in southern China over a 2-year period. Clinical data of patients who received IEAT were compared with those of patients receiving AEAT. We used multivariable logistic regression to identify the predictors for receiving IEAT and the risk factors affecting clinical outcomes. Results: A total of 213 patients were enrolled (median age, 61 years), of whom 103 (48.4%) received IEAT. IEAT was associated with empirical use of fluoroquinolones, male sex and age-adjusted Charlson comorbidity index (aCCI) score > 6. Hospital length of stay (LOS) was longer for patients who received IEAT than for those who received AEAT (13.6 +/- 8.6 days vs. 10.8 +/- 7.9 days; P = 0.008). IEAT was an independent risk factor for longer LOS along with aCCI score >= 2, lung disease and cardiac disease. Conclusion: Empirical use of fluoroquinolones for UTIs should be avoided, especially in male patients with aCCI score > 6. Improved empirical antimicrobial therapy may have a beneficial impact in reducing bacterial resistance and healthcare costs by decreasing the LOS. Therefore, interventions to promote indepth antibiotic stewardship programmes in China are needed.
