Abstract

Introduction: Urinary tract infection (UTI) is a serious health problem affecting millions of people every year. Inappropriate antibiotic prescriptions put patients at risk and lead to bacterial resistance and elevated costs.

Aims: Study aims were to assess the prevalence and antibiotic-treatment patterns of community acquired UTIs, prevalence and types of antibiotic-prescribing errors, and the cost of inappropriate antibiotic use.

Methods: This was a retrospective cross-sectional study conducted over a 3-month period in an emergency department in Saudi Arabia.

Results: During the study period, 1,449 patients were diagnosed with UTIs, including pediatric (18.6%), adult (59.2%), and elderly (22.2%) patients. The overall prevalence of UTIs was 9.9% of total visits. Broad-spectrum antibiotics were prescribed for 85% of patients. Three main antibiotics were prescribed: cephalosporin (39%), penicillin (26%), and fluoroquinolone (22%). The overall prevalence of inappropriate antibiotic prescription with at least one type of error was 46.2% (pediatrics 51%, adults 46%, elderly 47%). Errors were dose (37%), duration (11%), frequency (6%), and antibiotic selection (2.4%). Dose error was significantly greater in pediatric patients (P=0.001). Duration error was higher among adults and the elderly (P=0.014). Significantly more inappropriate cephalosporin prescriptions were seen in adults (P=0.001), while penicillin had significantly higher errors in pediatric patients. Positive urine culture was seen in 34.9% of patients, and the most common microorganism was Escherichia coli (51%). The mean cost of care for one episode of UTI was US$134.56±$31.34 (95% CI $132.94-$136.17). Treatment of UTI was more costly in women (63.9% of total cost), adults (59.2%), and those using broad-spectrum antibiotics (86.5%). There were statistically significant associations among sex, age, spectrum of antibiotic, category of antibiotic, and inappropriate cost.

Conclusion: The results revealed a significant level of inappropriate use of antibiotics in the treatment of UTIs in the emergency department.
