Antibiotic resistance in treating UTIs highest in aged care facilities: study · New data from UNSW Sydney reveals that UTIs caused by E. coli in aged care facilities in Australia show higher antibiotic resistance compared to hospitals and the wider community, with a resistance rate of 20-30%. · The study, led by A/Prof. Li Zhang, also found a reduction in UTI antibiotic resistance during the COVID-19 pandemic. · This research can help guide future treatment decisions for UTIs, prompting the need for clinicians and policymakers to reevaluate trimethoprim as the first-line antibiotic for UTIs in Australia, considering the evolving resistance patterns. · The team aims to further investigate the origins of highly resistant E. coli strains in aged care facilities to better address antibiotic resistance challenges in UTI treatment.
