Background And ObjectivesThe IDSA has published guidelines for the treatment of urinary tract infections, recommending limiting treatment to symptomatic patients and pregnant females. Our objective is to elucidate current practice patterns among emergency physicians (EPs) in treating positive urine cultures in various clinical situations.MethodsThis study employed a cross-sectional design utilizing a questionnaire addressing nine common scenarios encountered by EPs in the follow-up of a positive urine culture. The questionnaire was conducted using RedCap and distributed via email to current and former physicians and residents across our hospital network. Demographic information included years of training and practice setting. For each of nine clinical scenarios, Physicians were asked if they would treat with antibiotics. Results were then analyzed by tabulating percentage of responses and 95% confidence intervals.ResultsOf 120 respondents, 40.8% worked in academic centers with emergency medicine residencies, 37.5% in large community hospitals, and 20.67% in small community hospitals. Responses came from 14 residents, 33 attendings < 5 years out of training, 23 attendings 5-9 years out of training, 37 attendings 10-20 years out of training, and 13 attendings > 20 beyond training. Asymptomatic young women were treated by 34.2% (95% CI 25.91-43.46%) while asymptomatic elderly women were treated by 50% (95% CI 40.79-59.21%) of EPs. All EPs (95% CI 96.13-100%) chose to treat a symptomatic male and 99.2% (95% CI 94.77-99.96%) chose to treat an asymptomatic pregnant female. Elderly females after a fall were treated by 63.3% (95% CI 54-71.8%) of EPs while elderly males with confusion and a fall were treated by 96.7% (95% CI 91.18-98.93%). Asymptomatic males with a chronic Foley catheter were treated by 28.2% (95% CI 20.67-37.4%) of EPs and 46.7% (95%CI 37.59-55.97%) would treat an asymptomatic middle-aged female with diabetes. Finally, 92.5% (95% CI 85.85-96.3%) of EPs chose to treat an asymptomatic kidney transplant patient.ConclusionEPs in varied training stages and practice settings have significant practice variation in the treatment of positive urine cultures, particularly in the geriatric population, often prescribing antibiotics to patients where clear, specific and data-driven IDSA guidelines suggest treatment is unnecessary and potentially harmful.© 2022.
