Assessment of nationally recommended antibiotics for treatment of UTI in U.S.-Mexico border emergency departments
Abstract
BACKGROUND: Urinary tract infections (UTIs) seen in the emergency department are commonly treated as an outpatient with oral antibiotics. Given that antibiotics are available for over-the-counter purchase in Mexico, there is speculation that potential misuse and overuse of antibiotics in United States-Mexico border areas could lead to antibiotic resistance patterns that would render some empiric treatments for UTIs less effective. The purpose of this study was to examine the effectiveness of Infectious Disease Society of America (IDSA) guideline-recommended antibiotics for treatment of outpatient UTI diagnosed in the emergency department. Data were collected from a county hospital on the U.S.-Mexico border with a metropolitan area of over 2 million people. Secondary analysis included frequency of urine culture isolated, resistance rates of urine pathogens, and prescriber habits.
METHODS: This study was a retrospective chart review of adult patients diagnosed and treated for UTI from August 1, 2019, to February 29, 2020. Culture results of included patients were analyzed against in vitro-tested antibiotics. Bacterial isolate frequency, resistance rates, and prescribing habits were collected.
RESULTS: A total of 985 patient charts were reviewed, of which 520 patients met inclusion criteria for analysis of prescribing habits. Of these, 329 positive bacterial culture growths were included in the analysis of antibiotic resistance rates. Oral antibiotics with comparatively lower…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 520 participants or records.
