Prior Antibiotic Use Increases Risk of Urinary Tract Infections Caused by Resistant Escherichia coli among Elderly in Primary Care: A Case-Control Study (vol 11, 1382, 2022)

Summary: We investigated the impact of prior antibiotic use on multi-resistant Escherichia coli urinary tract infections (UTIs) among elderly patients in general practice. The study found that exposure to antibiotics within 90 days prior to the UTI episode significantly increased the odds of resistance to all four antibiotics. Mecillinam showed the lowest increase in resistance, suggesting it as a favorable antibiotic choice.
