- W4221027786 abstract "Abstract Background: Increasing antimicrobial resistance in uropathogens is a clinical challenge to emergency physicians as antibiotics should be selected before an infecting pathogen or its antibiotic resistance profile is confirmed. This single-center retrospective study evaluated patients diagnosed with upper urinary tract infection (UTI) in the emergency department (ED) between January 2020 and June 2021 to develop a predictive model for antibiotic resistance of uropathogens, using machine learning (ML) algorithmsResults: Forty variables were used to train the model for predicting resistance to ciprofloxacin and the presence of ESBL of urinary pathogens. Model performance with the XGBoost Gradient-Boosted Decision Tree (GBDT) was compared with that of empirical treatment (ET) according to effectiveness of antibiotic selected and appropriateness of selection with respect to antibiotic stewardship. Two prediction models using different decision thresholds were developed. The probability of using ineffective antibiotics in the ED was significantly lowered by 13.3% in the GDBT 0.25 using a decision threshold of 0.25 than in the ET model. Further, the rate of appropriate use of narrow-spectrum antibiotics was higher by 7.4 times in the GBDT 0.44 model than in the ET model, while the ineffectiveness level was maintained.Conclusions: An ML model is potentially useful for predicting antibiotic resistance, improving the effectiveness and appropriateness of empirical antimicrobial treatment in patients with upper UTI in the ED. The model could be a point-of-care decision support tool to guide clinicians towards individualized antibiotic prescription." @default.
