A descriptive, retrospective cross-sectional study on the age wise distribution and antimicrobial resistance patterns of clinical bacterial isolates in a hospital in Al-Hilla city 2024-2025

Antimicrobial resistance (AMR) has become a global public health concern, with increasing prevalence across all age groups. This study aimed to evaluate the distribution and resistance patterns of bacterial pathogens isolated from patients of different age groups in a hospital in Al_ Hilla during the years 2024 _ 2025. A retrospective analysis was conducted using laboratory data from bacterial cultures and antibiotic sensitivity tests. The results showed that multidrug-resistant organisms (MDR) were most prevalent among elderly patients, while younger age groups exhibited higher susceptibility to commonly used antibiotics. Escherichia coli and p. aeruginosa were the most frequently isolated organisms. The findings highlight the need for age-specific antibiotic stewardship strategies and continuous surveillance to combat the rise of drug-resistant infections.
