Multidrug-Resistant Urinary Tract Infections in Resource-Limited Settings: Resistance Trends and Predictive Modeling

A retrospective cross-sectional study was conducted on 317 culture-confirmed UTI cases at Al-Rafa Laboratory, Ibb University, Yemen (March 2023–November 2024). Bacterial identification and antimicrobial susceptibility testing were performed using standard protocols. MDR-UTI was defined as resistance to three or more antibiotic classes. Multivariable logistic regression identified independent MDR risk factors, and model performance was assessed using receiver operating characteristic (ROC) analysis.
