Antimicrobial resistance (AMR) is a substantial threat in Saudi Arabia. We focus on Methicillin-Resistant S. aureus (MRSA), carbapenem-resistant strains, Extended-Spectrum Beta-Lactamases (ESBL) producers, and colistin-resistance. We analyzed 559 samples (blood, urine, wound specimens). ESBLs were the most prevalent (55%), followed by MRSA (22%), combined ESBL and CRE resistance (18%). The ESBL phenotype had a colistin resistance of 71.3%, while ESBL and CRE phenotypes had 22.9%, and CRE had 5.8%. The age group 50+ had 58.7% resistance phenotypes. Urine samples had 49% prevalence of resistant phenotypes, while the highest rate according to ward location was at the OPD (55.8%).
The study highlights critical trends of AMR, emphasizing the urgency to antibiotic regulations, professional development for healthcare professionals, and local studies on AMR for targeted intervention.
